Notes to Consolidated Financial Statements [Abstract]
Significant Accounting Policies And Other Financial Data	SEMPRA ENERGY AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	NOTE 1. SIGNIFICANT ACCOUNTING POLICIES AND OTHER FINANCIAL DATA
	PRINCIPLES OF CONSOLIDATION
	Sempra Energy
	Sempra Energy’s Consolidated Financial Statements include the accounts of Sempra Energy, a California-based Fortune 500 energy-services holding company, and its consolidated subsidiaries and variable interest entities (VIEs). Sempra Energy’s principal operating units are
	San Diego Gas & Electric Company (SDG&E) and Southern California Gas Company (SoCalGas), which are separate, reportable segments;
	Sempra International, which includes our Sempra South American Utilities and Sempra Mexico reportable segments; and
	Sempra U.S. Gas & Power, which includes our Sempra Renewables and Sempra Natural Gas reportable segments.
	We provide descriptions of each of our segments in Note 16.
	We refer to SDG&E and SoCalGas collectively as the California Utilities, which do not include the utilities in our Sempra International and Sempra U.S. Gas & Power operating units. Sempra Global is the holding company for most of our subsidiaries that are not subject to California utility regulation. All references in these Notes to “Sempra International,” “Sempra U.S. Gas & Power” and their respective reportable segments are not intended to refer to any legal entity with the same or similar name.
	Our Sempra Mexico segment includes the operating companies of our subsidiary, Infraestructura Energética Nova, S.A.B. de C.V. (IEnova), as well as certain holding companies and risk management activity. We discuss IEnova below under “Noncontrolling Interests – Sale of Noncontrolling Interests.”
	Sempra Energy uses the equity method to account for investments in affiliated companies over which we have the ability to exercise significant influence, but not control. We discuss our investments in unconsolidated entities in Notes 3 and 4.
	SDG&E
	SDG&E’s Consolidated Financial Statements include its accounts and the accounts of a VIE of which SDG&E is the primary beneficiary, as we discuss below under “Variable Interest Entities.” SDG&E’s common stock is wholly owned by Enova Corporation, which is a wholly owned subsidiary of Sempra Energy.
	SoCalGas
	SoCalGas’ Consolidated Financial Statements include its accounts and the de minimis accounts of inactive subsidiaries. SoCalGas’ common stock is wholly owned by Pacific Enterprises (PE), which is a wholly owned subsidiary of Sempra Energy.
	BASIS OF PRESENTATION
	This is a combined report of Sempra Energy, SDG&E and SoCalGas. We provide separate information for SDG&E and SoCalGas as required. References in this report to “we,” “our” and “Sempra Energy Consolidated” are to Sempra Energy and its consolidated entities, unless otherwise indicated by the context. We have eliminated intercompany accounts and transactions within the consolidated financial statements of each reporting entity.
	Regulated Operations
	Sempra South American Utilities has controlling interests in two electric distribution utilities in South America, Chilquinta Energía S.A. (Chilquinta Energía) in Chile and Luz del Sur S.A.A. (Luz del Sur) in Peru and their subsidiaries. Sempra Natural Gas owns Mobile Gas Service Corporation (Mobile Gas) in southwest Alabama and Willmut Gas Company (Willmut Gas) in Mississippi, and Sempra Mexico owns Ecogas México, S. de R.L. de C.V. (Ecogas) in northern Mexico, all natural gas distribution utilities. The California Utilities, Sempra Natural Gas’ Mobile Gas and Willmut Gas, and Sempra Mexico’s Ecogas prepare their financial statements in accordance with the provisions of accounting principles generally accepted in the United States of America (U.S. GAAP) governing regulated operations, as we discuss below under “Regulatory Matters.” We discuss revenue recognition at our utilities in “Revenues–Utilities” below.
	Use of Estimates in the Preparation of the Financial Statements
	We have prepared our Consolidated Financial Statements in conformity with U.S. GAAP. This requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes, including the disclosure of contingent assets and liabilities at the date of the financial statements. Although we believe the estimates and assumptions are reasonable, actual amounts ultimately may differ significantly from those estimates.
	Subsequent Events
	We evaluated events and transactions that occurred after December 31, 2014 through the date the financial statements were issued, and in the opinion of management, the accompanying statements reflect all adjustments necessary for a fair presentation.
	REGULATORY MATTERS
	Effects of Regulation
	The accounting policies of our regulated utility subsidiaries in California, SDG&E and SoCalGas, conform with U.S. GAAP for regulated enterprises and reflect the policies of the California Public Utilities Commission (CPUC) and the Federal Energy Regulatory Commission (FERC).
	The California Utilities prepare their financial statements in accordance with U.S. GAAP provisions governing regulated operations. Under these provisions, a regulated utility records regulatory assets, which are generally costs that would otherwise be charged to expense, if it is probable that, through the ratemaking process, the utility will recover those assets from customers. To the extent that recovery is no longer probable, the related regulatory assets are written off. Regulatory liabilities generally represent amounts collected from customers in advance of the actual expenditure by the utility. If the actual expenditures are less than amounts previously collected from ratepayers, the excess would be refunded to customers, generally by reducing future rates. Regulatory liabilities may also arise from other transactions such as unrealized gains on fixed price contracts and other derivatives or certain deferred income tax benefits that are passed through to customers in future rates. In addition, the California Utilities record regulatory liabilities when the CPUC or the FERC requires a refund to be made to customers or has required that a gain or other transaction of net allowable costs be given to customers over future periods.
	Determining probability of recovery requires significant judgment by management and may include, but is not limited to, consideration of:
	the nature of the event giving rise to the assessment;
	existing statutes and regulatory code;
	legal precedents;
	regulatory principles and analogous regulatory actions;
	testimony presented in regulatory hearings;
	proposed regulatory decisions;
	final regulatory orders;
	a commission-authorized mechanism established for the accumulation of costs;
	status of applications for rehearings or state court appeals;
	specific approval from a commission; and
	historical experience.
	Our other natural gas distribution utilities, Mobile Gas, Willmut Gas and Ecogas, also apply U.S. GAAP for regulated utilities to their operations.
	We provide information concerning regulatory assets and liabilities below in “Regulatory Balancing Accounts” and “Regulatory Assets and Liabilities” and in Notes 13 and 14.
	Regulatory Balancing Accounts
	The following table summarizes our regulatory balancing accounts at December 31.

	Over- and undercollected regulatory balancing accounts reflect the difference between customer billings and recorded or CPUC-authorized costs, primarily commodity costs. Amounts in the balancing accounts are recoverable (receivable) or refundable (payable) in future rates, subject to CPUC approval. Balancing account treatment eliminates the impact on earnings from variances in the covered costs from authorized amounts. Absent balancing account treatment, variations in the cost of fuel supply and certain operating and maintenance costs from amounts approved by the CPUC would increase volatility in utility earnings.
	We provide additional information about regulatory matters in Notes 13, 14 and 15.
	Regulatory Assets and Liabilities
	We show the details of regulatory assets and liabilities in the following table, and discuss each of them separately below.

In the tables above:
Regulatory assets arising from fixed-price contracts and other derivatives are offset by corresponding liabilities arising from purchased power and natural gas commodity and transportation contracts. The regulatory asset is increased/decreased based on changes in the fair market value of the contracts. It is also reduced as payments are made for commodities and services under these contracts.
Regulatory assets arising from the San Onofre Nuclear Generating Station (SONGS) plant closure are associated with SDG&E’s investment in SONGS as of the plant closure date and the cost of operations since Units 2 and 3 were taken offline, as we discuss further in Note 13.
Regulatory assets arising from costs related to wildfire litigation are costs in excess of liability insurance coverage and amounts recovered from third parties, as we discuss in Note 14 under “Excess Wildfire Claims Cost Recovery” and Note 15 under “SDG&E — 2007 Wildfire Litigation.”
Deferred taxes recoverable in rates are based on current regulatory ratemaking and income tax laws. SDG&E and SoCalGas expect to recover net regulatory assets related to deferred income taxes over the lives of the assets that give rise to the accumulated deferred income tax liabilities.
Regulatory assets/liabilities related to pension and other postretirement benefit obligations are offset by corresponding liabilities/assets and are being recovered in rates as the plans are funded.
Regulatory assets related to unamortized losses on reacquired debt are recovered over the remaining amortization periods of the losses on reacquired debt. These periods range from 5 months to 13 years for SDG&E and from 7 years to 11 years for SoCalGas.
Regulatory assets related to environmental costs represent the portion of our environmental liability recognized at the end of the period in excess of the amount that has been recovered through rates charged to customers. We expect this amount to be recovered in future rates as expenditures are made.
The regulatory asset related to the legacy meters removed from service and replaced under the Smart Meter Program is their undepreciated value. SDG&E is recovering this asset over a remaining 3-year period in ratebase.
The regulatory asset related to Sunrise Powerlink fire mitigation is offset by a corresponding liability for the funding of a trust to cover the mitigation costs. SDG&E expects to recover the regulatory asset in rates as the trust is funded over a remaining 55-year period. We discuss the trust further in Note 15.
FAIR VALUE MEASUREMENTS
We apply recurring fair value measurements to certain assets and liabilities, primarily nuclear decommissioning and benefit plan trust assets and other miscellaneous derivatives. “Fair value” is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).
A fair value measurement reflects the assumptions market participants would use in pricing an asset or liability based on the best available information. These assumptions include the risk inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. Also, we consider an issuer’s credit standing when measuring its liabilities at fair value.
We establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows:
Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Our Level 1 financial instruments primarily consist of listed equities, U.S. government treasury securities and exchange-traded derivatives.
Level 2 – Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including:
quoted forward prices for commodities
time value
current market and contractual prices for the underlying instruments
volatility factors
other relevant economic measures
Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Our financial instruments in this category include domestic corporate bonds, municipal bonds and other foreign bonds, primarily in the Nuclear Decommissioning Trusts and in our pension and postretirement benefit plans, and non-exchange-traded derivatives such as interest rate instruments and over-the-counter (OTC) forwards and options.
Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value from the perspective of a market participant. Substantially all of our Level 3 financial instruments are related to congestion revenue rights (CRRs) at SDG&E.
CASH AND CASH EQUIVALENTS
Cash equivalents are highly liquid investments with maturities of three months or less at the date of purchase.
RESTRICTED CASH
Restricted cash at Sempra Energy, including amounts at SDG&E discussed below, was $40 million and $49 million at December 31, 2014 and 2013, respectively. Of this, $11 million and $24 million was classified as current and $29 million and $25 million was classified as noncurrent at December 31, 2014 and 2013, respectively.
SDG&E had $19 million and $31 million of restricted cash at December 31, 2014 and 2013, respectively, which represents funds held by a trustee for Otay Mesa VIE (see “Variable Interest Entities—Otay Mesa VIE” below) to pay certain operating costs. Of this, $8 million and $6 million was classified as current and $11 million and $25 million was classified as noncurrent at December 31, 2014 and 2013, respectively.
Sempra Mexico had restricted cash of $18 million classified as noncurrent and $12 million classified as current at December 31, 2014 and 2013, respectively, representing funds to pay for rights of way, license fees, permits, topographic surveys and other costs pursuant to trust agreements related to a pipeline project.
Sempra Renewables had restricted cash of $3 million and $6 million classified as current at December 31, 2014 and 2013, respectively, primarily representing funds held in accordance with debt agreements at Copper Mountain Solar 1.
COLLECTION ALLOWANCES
We record allowances for the collection of trade and other accounts and notes receivable, which include allowances for doubtful customer accounts and for other receivables. We show the changes in these allowances in the table below:
COLLECTION ALLOWANCES

Write-offs of uncollectible accounts		-10		-9		-10
Allowances for collection of receivables at December 31	$	17	$	12	$	14
We evaluate accounts receivable collectibility using a combination of factors, including past due status based on contractual terms, trends in write-offs, the age of the receivable, counterparty creditworthiness, economic conditions and specific events, such as bankruptcies. Adjustments to the allowance for doubtful accounts are made when necessary based on the results of analysis, the aging of receivables, and historical and industry trends.
We write off accounts receivable in the period in which we deem the receivable to be uncollectible. We record recoveries of accounts receivable previously written off when it is known that they will be received.
INVENTORIES
The California Utilities value natural gas inventory by the last-in first-out (LIFO) method. As inventories are sold, differences between the LIFO valuation and the estimated replacement cost are reflected in customer rates. Materials and supplies at the California Utilities are generally valued at the lower of average cost or market.
Sempra South American Utilities, Sempra Mexico and Sempra Natural Gas value natural gas inventory and materials and supplies at the lower of average cost or market. Sempra Mexico and Sempra Natural Gas value liquefied natural gas (LNG) inventory by the first-in first-out method.
The components of inventories by segment are as follows:

U.S. TREASURY GRANTS
At December 31, 2012, we had receivables for U.S. Treasury grants based on eligible costs at certain of our renewable generating facilities. During the first quarter of 2013, the federal government imposed automatic federal budget cuts, known as “sequestration,” as required by The Budget Control Act of 2011. As a result, we recorded a reduction to our grants receivable of $23 million and a reversal of income tax benefit of $5 million during the first quarter of 2013. Later in 2013, we received $238 million in cash for the remaining grants receivable.
INCOME TAXES
Income tax expense includes current and deferred income taxes from operations during the year. We record deferred income taxes for temporary differences between the book and the tax basis of assets and liabilities. Investment tax credits from prior years are amortized to income by the California Utilities over the estimated service lives of the properties as required by the CPUC. At our other businesses, we reduce the book basis of the related asset by the amount of investment tax credit earned. At Sempra Renewables, production tax credits are recognized in income tax expense as earned.
The California Utilities, Mobile Gas and Willmut Gas recognize
regulatory assets to offset deferred tax liabilities if it is probable that the amounts will be recovered from customers; and
regulatory liabilities to offset deferred tax assets if it is probable that the amounts will be returned to customers.
We currently do not record deferred income taxes for basis differences between financial statement and income tax investment amounts in non-U.S. subsidiaries and non-U.S. joint ventures because their cumulative undistributed earnings are indefinitely reinvested.
When there are uncertainties related to potential income tax benefits, in order to qualify for recognition, the position we take has to have at least a “more likely than not” chance of being sustained (based on the position’s technical merits) upon challenge by the respective authorities. The term “more likely than not” means a likelihood of more than 50 percent. Otherwise, we may not recognize any of the potential tax benefit associated with the position. We recognize a benefit for a tax position that meets the “more likely than not” criterion at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon its effective resolution.
Unrecognized tax benefits involve management’s judgment regarding the likelihood of the benefit being sustained. The final resolution of uncertain tax positions could result in adjustments to recorded amounts and may affect our results of operations, financial position and cash flows.
We provide additional information about income taxes in Note 6.
GREENHOUSE GAS ALLOWANCES
The California Utilities, Sempra Mexico and Sempra Natural Gas are required by California Assembly Bill 32 to acquire greenhouse gas allowances for every metric ton of carbon dioxide equivalent emitted into the atmosphere during electric generation and natural gas transportation. We record greenhouse gas allowances at the lower of weighted average cost or market, and include them in Other Current Assets and Sundry on the Consolidated Balance Sheets based on the dates that they are required to be surrendered. We measure the compliance obligation, which is based on emissions, at the carrying value of allowances held plus the fair value of additional allowances necessary to satisfy the obligation. We include the obligation in Other Current Liabilities and Deferred Credits on the Consolidated Balance Sheets based on the dates that the allowances will be surrendered. We remove the assets and liabilities from the balance sheets as the allowances are surrendered.
The California Utilities expect that costs and revenues associated with the greenhouse gas program will be recorded through Regulatory Balancing Accounts on the Consolidated Balance Sheets.
RENEWABLE ENERGY CERTIFICATES
Renewable energy certificates (RECs) represent property rights established by governmental agencies for the environmental, social, and other nonpower qualities of renewable electricity generation. A REC, and its associated attributes and benefits, can be sold separately from the underlying physical electricity associated with a renewable-based generation source in certain markets.
Retail sellers of electricity obtain RECs through renewable power purchase agreements, internal generation or separate purchases in the market to comply with renewable portfolio standards established by the governmental agencies. RECs are the mechanism used to verify renewable portfolio standards compliance. The cost of RECs is recorded in Cost of Electric Fuel and Purchased Power, which is recoverable in rates, on the Consolidated Statements of Operations.
PROPERTY, PLANT AND EQUIPMENT
Property, plant and equipment primarily represents the buildings, equipment and other facilities used by the California Utilities to provide natural gas and electric utility services, and by Sempra International and Sempra U.S. Gas & Power, including construction work in progress at these operating units. Property, plant and equipment also includes lease improvements and other equipment at Parent, as well as property acquired under a build-to-suit lease included in construction work in progress.
Our plant costs include
labor
materials and contract services
expenditures for replacement parts incurred during a major maintenance outage of a generating plant
In addition, the cost of our utility plant and selected non-utility regulated projects at Sempra Mexico and Sempra Natural Gas includes an allowance for funds used during construction (AFUDC). We discuss AFUDC below. The cost of non-utility plant includes capitalized interest.
Maintenance costs are expensed as incurred. The cost of most retired depreciable utility plant minus salvage value is charged to accumulated depreciation.
We discuss assets pledged as security for loans in Note 5.

-3	Includes capital lease assets of $19 million and $23 million at December 31, 2014 and 2013, respectively.
-4	Includes capital lease assets of $27 million and $33 million at December 31, 2014 and 2013, respectively.
-5	December 31, 2014 balances include $150 million, $191 million and $24 million of utility plant, primarily pipelines and other distribution assets, at Ecogas, Mobile Gas and Willmut Gas, respectively. December 31, 2013 balances include $155 million, $180 million and $22 million of utility plant, primarily pipelines and other distribution assets, at Ecogas, Mobile Gas and Willmut Gas, respectively.
-6	Estimated useful lives are for land rights.
Depreciation expense is based on the straight-line method over the useful lives of the assets or, for the California Utilities, a shorter period prescribed by the CPUC. Depreciation expense is computed using the straight-line method over the asset’s estimated original composite useful life, the CPUC-prescribed period or the remaining term of the site leases, whichever is shortest. Depreciation expense for Sempra Energy for the years ended December 31, 2014, 2013 and 2012, was $1,146 million, $1,103 million and $1,080 million, respectively. Depreciation expense for SDG&E for the years ended December 31, 2014, 2013 and 2012, was $530 million, $494 million and $490 million, respectively. Depreciation expense for SoCalGas for the years ended December 31, 2014, 2013 and 2012, was $431 million, $383 million and $362 million, respectively.

-2	Includes accumulated depreciation for assets under capital lease of $27 million and $31 million at December 31, 2014 and 2013, respectively.
-3	December 31, 2014 balances include $37 million, $29 million and $2 million of accumulated depreciation for utility plant at Ecogas, Mobile Gas and Willmut Gas, respectively. December 31, 2013 balances include $38 million, $25 million and $2 million of accumulated depreciation for utility plant at Ecogas, Mobile Gas and Willmut Gas, respectively.
The California Utilities finance their construction projects with borrowed funds and equity funds. The CPUC and the FERC allow the recovery of the cost of these funds by the capitalization of AFUDC, calculated using rates authorized by the CPUC and the FERC, as a cost component of property, plant and equipment. The California Utilities earn a return on the capitalized AFUDC after the utility property is placed in service and recover the AFUDC from their customers over the expected useful lives of the assets.
Pipeline projects currently under construction by Sempra Mexico and Sempra Natural Gas that are both subject to certain regulation and meet U.S. GAAP regulatory accounting requirements record the impact of AFUDC related to equity. Beginning in the fourth quarter of 2013, Sempra Mexico began recording AFUDC equity for its Sonora Pipeline project, totaling $43 million and $19 million for the years ended December 31, 2014 and 2013, respectively.
Sempra International and Sempra U.S. Gas & Power businesses capitalize interest costs incurred to finance capital projects and interest on equity method investments that have not commenced planned principal operations. The California Utilities also capitalize certain interest costs.

GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill
Goodwill is the excess of the purchase price over the fair value of the identifiable net assets of acquired companies measured at the time of acquisition. Goodwill is not amortized but is tested for impairment annually on October 1 or whenever events or changes in circumstances necessitate an evaluation. Impairment of goodwill occurs when the carrying amount (book value) of goodwill exceeds its implied fair value. If the carrying value of the reporting unit, including goodwill, exceeds its fair value, and the book value of goodwill is greater than its fair value on the test date, we record a goodwill impairment loss.
For our annual goodwill impairment testing, under current U.S. GAAP guidance we have the option to first make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount before applying the two-step, quantitative goodwill impairment test. If we elect to perform the qualitative assessment, we evaluate relevant events and circumstances, including but not limited to, macroeconomic conditions, industry and market considerations, cost factors, changes in key personnel and the overall financial performance of the reporting unit. If, after assessing these qualitative factors, we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform the two-step goodwill impairment test. When we perform the two-step, quantitative goodwill impairment test, we exercise judgment to develop estimates of the fair value of the reporting unit and the corresponding goodwill. Our fair value estimates are developed from the perspective of a knowledgeable market participant. We consider observable transactions in the marketplace for similar investments, if available, as well as an income-based approach such as discounted cash flow analysis. A discounted cash flow analysis may be based directly on anticipated future revenues and expenses and may be performed based on free cash flows generated within the reporting unit. Critical assumptions that affect our estimates of fair value may include
consideration of market transactions
future cash flows
the appropriate risk-adjusted discount rate
country risk
entity risk

Amortization expense for such intangible assets was $10 million in each of 2014, 2013 and 2012. We estimate the amortization expense for the next five years to be $10 million per year.
LONG-LIVED ASSETS
We test long-lived assets for recoverability whenever events or changes in circumstances have occurred that may affect the recoverability or the estimated useful lives of long-lived assets. Long-lived assets include intangible assets subject to amortization, but do not include investments in unconsolidated subsidiaries. Events or changes in circumstances that indicate that the carrying amount of a long-lived asset may not be recoverable may include
significant decreases in the market price of an asset
a significant adverse change in the extent or manner in which we use an asset or in its physical condition
a significant adverse change in legal or regulatory factors or in the business climate that could affect the value of an asset
a current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection of continuing losses associated with the use of a long-lived asset
a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life
Impairment of long-lived assets occurs when the estimated future undiscounted cash flows are less than the carrying amount of the assets. If that comparison indicates that the assets’ carrying value may not be recoverable, the impairment is measured based on the difference between the carrying amount and the fair value of the assets. This evaluation is performed at the lowest level for which separately identifiable cash flows exist.
VARIABLE INTEREST ENTITIES (VIE)
We consolidate a VIE if we are the primary beneficiary of the VIE. Our determination of whether we are the primary beneficiary is based upon qualitative and quantitative analyses, which assess
the purpose and design of the VIE;
the nature of the VIE’s risks and the risks we absorb;
the power to direct activities that most significantly impact the economic performance of the VIE; and
the obligation to absorb losses or right to receive benefits that could be significant to the VIE.
SDG&E
Tolling Agreements
SDG&E has agreements under which it purchases power generated by facilities for which it supplies all of the natural gas to fuel the power plant (i.e., tolling agreements). SDG&E’s obligation to absorb natural gas costs may be a significant variable interest. In addition, SDG&E has the power to direct the dispatch of electricity generated by these facilities. Based upon our analysis, the ability to direct the dispatch of electricity may have the most significant impact on the economic performance of the entity owning the generating facility because of the associated exposure to the cost of natural gas, which fuels the plants, and the value of electricity produced. To the extent that SDG&E (1) is obligated to purchase and provide fuel to operate the facility, (2) has the power to direct the dispatch, and (3) purchases all of the output from the facility for a substantial portion of the facility’s useful life, SDG&E may be the primary beneficiary of the entity owning the generating facility. SDG&E determines if it is the primary beneficiary in these cases based on a qualitative approach in which we consider the operational characteristics of the facility, including its expected power generation output relative to its capacity to generate and the financial structure of the entity, among other factors. If we determine that SDG&E is the primary beneficiary, SDG&E and Sempra Energy consolidate the entity that owns the facility as a VIE, as we discuss below.
Otay Mesa VIE
SDG&E has an agreement to purchase power generated at the Otay Mesa Energy Center (OMEC), a 605-megawatt (MW) generating facility. In addition to tolling, the agreement provides SDG&E with the option to purchase the power plant at the end of the contract term in 2019, or upon earlier termination of the purchased-power agreement, at a predetermined price subject to adjustments based on performance of the facility. If SDG&E does not exercise its option, under certain circumstances, it may be required to purchase the power plant at a predetermined price, which we refer to as the put option.
The facility owner, Otay Mesa Energy Center LLC (OMEC LLC), is a VIE (Otay Mesa VIE), of which SDG&E is the primary beneficiary. SDG&E has no OMEC LLC voting rights and does not operate OMEC. In addition to the risks absorbed under the tolling agreement, SDG&E absorbs separately through the put option a significant portion of the risk that the value of Otay Mesa VIE could decline. Accordingly, SDG&E and Sempra Energy have consolidated Otay Mesa VIE. Otay Mesa VIE’s equity of $60 million at December 31, 2014 and $91 million at December 31, 2013 is included on the Consolidated Balance Sheets in Other Noncontrolling Interests for Sempra Energy and in Noncontrolling Interest for SDG&E.
OMEC LLC has a loan outstanding of $325 million at December 31, 2014, the proceeds of which were used for the construction of OMEC. The loan is with third party lenders and is secured by OMEC’s property, plant and equipment. SDG&E is not a party to the loan agreement and does not have any additional implicit or explicit financial responsibility to OMEC LLC. The loan fully matures in April 2019 and bears interest at rates varying with market rates. In addition, OMEC LLC has entered into interest rate swap agreements to moderate its exposure to interest rate changes. We provide additional information concerning the interest rate swaps in Note 9.
Cameron LNG Holdings
Sempra Energy’s equity-method investment in Cameron LNG Holdings is considered to be a VIE generally due to contractual provisions that transfer certain risks to customers. Sempra Energy is not the primary beneficiary because we do not have the power to direct the most significant activities of Cameron LNG Holdings. We will continue to evaluate Cameron LNG Holdings for any changes that may impact our determination of the primary beneficiary. The carrying value of our investment in Cameron LNG holdings at December 31, 2014 was $1,007 million, as we discuss in Note 4. Our maximum exposure to loss includes the carrying value of our investment and the guarantees discussed in Note 4.
Other Variable Interest Entities
SDG&E’s power procurement is subject to reliability requirements that may require SDG&E to enter into various power purchase arrangements which include variable interests. SDG&E evaluates the respective entities to determine if variable interests exist and, based on the qualitative and quantitative analyses described above, if SDG&E, and thereby Sempra Energy, is the primary beneficiary. SDG&E has determined that no contracts, other than the one relating to Otay Mesa VIE mentioned above, result in SDG&E being the primary beneficiary at December 31, 2014. In addition to the tolling agreements described above, other variable interests involve various elements of fuel and power costs, including certain construction costs, tax credits, and other components of cash flow expected to be paid to or received by our counterparties. In most of these cases, the expectation of variability is not substantial, and SDG&E generally does not have the power to direct activities that most significantly impact the economic performance of the other VIEs. If our ongoing evaluation of these VIEs were to conclude that SDG&E becomes the primary beneficiary and consolidation by SDG&E becomes necessary, the effects are not expected to significantly affect the financial position, results of operations, or liquidity of SDG&E. In addition, SDG&E is not exposed to losses or gains as a result of these other VIEs, because all such variability would be recovered in rates.
Sempra Energy’s other operating units also enter into arrangements which could include variable interests. We evaluate these arrangements and applicable entities based upon the qualitative and quantitative analyses described above. Certain of these entities are service companies that are VIEs. As the primary beneficiary of these service companies, we consolidate them. In all other cases, we have determined that these contracts are not variable interests in a VIE and therefore are not subject to the U.S. GAAP requirements concerning the consolidation of VIEs.
The Consolidated Financial Statements of Sempra Energy and SDG&E include the following amounts associated with Otay Mesa VIE. The amounts are net of eliminations of transactions between SDG&E and Otay Mesa VIE. The financial statements of other consolidated VIEs are not material to the financial statements of Sempra Energy. The captions on the tables below correspond to SDG&E’s Consolidated Balance Sheets and Consolidated Statements of Operations.

ASSET RETIREMENT OBLIGATIONS
For tangible long-lived assets, we record asset retirement obligations for the present value of liabilities of future costs expected to be incurred when assets are retired from service, if the retirement process is legally required and if a reasonable estimate of fair value can be made. We also record a liability if a legal obligation to perform an asset retirement exists and can be reasonably estimated, but performance is conditional upon a future event. We record the estimated retirement cost over the life of the related asset by depreciating the present value of the obligation (measured at the time of the asset’s acquisition) and accreting the discount until the liability is settled. Rate-regulated entities, including the California Utilities, record regulatory assets or liabilities as a result of the timing difference between the recognition of costs in accordance with U.S. GAAP and costs recovered through the rate-making process.
We have recorded asset retirement obligations related to various assets, including:
SDG&E and SoCalGas
fuel and storage tanks
natural gas distribution systems
hazardous waste storage facilities
asbestos-containing construction materials
SDG&E
decommissioning of nuclear power facilities
electric distribution and transmission systems
site restoration of a former power plant
power generation plant (natural gas)

-2	Reclassification to liability held for sale - asset retirement obligation which is included in Other Current Liabilities on the Consolidated Balance Sheets, as we discuss in "Asset Held for Sale" in Note 3.
-3	The decreases in asset retirement obligations in 2013 at SDG&E and SoCalGas are due to revised estimates related to the 2012 General Rate Case (GRC) that received final approval in May 2013. At SDG&E, these revisions included increases in asset service lives ranging from 2 percent to 7 percent, and lower estimated cost of removal. At SoCalGas, the decrease includes increases in asset service lives ranging from 4 percent to 6 percent, partially offset by a higher estimated cost of removal.
-4	The decrease in asset retirement obligations in 2014 at SDG&E is due to revised estimates in an updated decommissioning cost study for the San Onofre Nuclear Generating Station, which we discuss in Note 13. The increase in asset retirement obligations in 2014 at SoCalGas is related to a change in estimates.
-5	The increase in asset retirement obligations in 2013 at SDG&E is due to revised estimates recorded in the third quarter of 2013 related to the early decommissioning of SONGS Units 2 and 3 (see Note 13).
CONTINGENCIES
We accrue losses for the estimated impacts of various conditions, situations or circumstances involving uncertain outcomes. For loss contingencies, we accrue the loss if an event has occurred on or before the balance sheet date and:
information available through the date we file our financial statements indicates it is probable that a loss has been incurred, given the likelihood of uncertain future events; and
the amount of the loss can be reasonably estimated.
We do not accrue contingencies that might result in gains. We continuously assess contingencies for litigation claims, environmental remediation and other events.
LEGAL FEES
Legal fees that are associated with a past event for which a liability has been recorded are accrued when it is probable that fees also will be incurred.
COMPREHENSIVE INCOME
Comprehensive income includes all changes in the equity of a business enterprise (except those resulting from investments by owners and distributions to owners), including:
foreign currency translation adjustments
changes in unamortized net actuarial gain or loss and prior service cost related to pension and other postretirement benefits plans
unrealized gains or losses on available-for-sale securities
certain hedging activities
The Consolidated Statements of Comprehensive Income show the changes in the components of other comprehensive income (loss) (OCI), including the amounts attributable to noncontrolling interests.

NONCONTROLLING INTERESTS
Ownership interests that are held by owners other than Sempra Energy and SDG&E in subsidiaries or entities consolidated by them are accounted for and reported as noncontrolling interests. As a result, noncontrolling interests are reported as a separate component of equity on the Consolidated Balance Sheets. Earnings/losses attributable to the noncontrolling interests are separately identified on the Consolidated Statements of Operations, and net income/loss and comprehensive income/loss attributable to the noncontrolling interests are separately identified on the Consolidated Statements of Comprehensive Income and Consolidated Statements of Changes in Equity.
Sale of Noncontrolling Interests
In the first quarter of 2013, Sempra Energy’s subsidiary, IEnova, completed a private offering in the U.S. and outside of Mexico and a concurrent public offering in Mexico of common stock. The aggregate shares of common stock sold in the offerings represent approximately 18.9 percent of IEnova’s outstanding ownership interest. IEnova is reported within the Sempra Mexico reportable segment.
The proceeds from the offerings, net of offering costs, were approximately $574 million in U.S. dollar equivalent. IEnova has used the net proceeds of the offerings primarily for general corporate purposes, and for the funding of its investments and ongoing expansion plans. Consistent with applicable accounting guidance, changes in noncontrolling interests that do not result in a change of control are accounted for as equity transactions. When there are changes in noncontrolling interests of a subsidiary that do not result in a change of control, any difference between carrying value and fair value related to the change in ownership is recorded as an adjustment to shareholders’ equity. As a result of the offerings, we recorded an increase in Sempra Energy’s shareholders’ equity of $135 million in the first quarter of 2013 for the sale of IEnova shares to noncontrolling interests.
IEnova is a separate legal entity, formerly known as Sempra México, S.A. de C.V., comprised primarily of Sempra Energy’s operations in Mexico. IEnova is included within our Sempra Mexico reportable segment, but is not the same in its entirety as the reportable segment. In addition to the IEnova operating companies, the Sempra Mexico segment includes, among other things, certain holding companies and risk management activity. Also, IEnova’s financial results are reported in Mexico under International Financial Reporting Standards (IFRS), as required by the Mexican Stock Exchange (La Bolsa Mexicana de Valores, S.A.B. de C.V., or BMV) where the shares are traded under the symbol IENOVA.
The private offering was exempt from registration under the U.S. Securities Act of 1933, as amended (the Securities Act), and shares in the private offering were offered and sold only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside of the United States, in accordance with Regulation S under the Securities Act. The shares were not registered under the Securities Act or any state securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable securities laws.
Purchase of Noncontrolling Interests
On December 10, 2014, we purchased 18,625,594 Luz del Sur shares for $74 million, increasing Sempra South American Utilities’ ownership from 79.8 percent to 83.6 percent.
Chilquinta Energía owned 85 percent of Luzlinares S.A. (Luzlinares) through October 31, 2012. On November 26, 2012, Chilquinta Energía purchased the remaining 15-percent ownership interest in Luzlinares for $7 million in cash.
Preferred Stock
The preferred stock at SoCalGas is presented at Sempra Energy as a noncontrolling interest at December 31, 2014 and 2013. The preferred stock of SDG&E at December 31, 2012 was contingently redeemable preferred stock and was fully redeemed in October 2013, as we discuss in Note 11. At Sempra Energy, the preferred stock dividends of SDG&E and SoCalGas are charges against income related to noncontrolling interests. We provide additional information concerning preferred stock in Note 11.
Other Noncontrolling Interests
At December 31, 2014 and 2013, we reported the following noncontrolling ownership interests held by others (not including preferred shareholders) recorded in Other Noncontrolling Interests in Total Equity on Sempra Energy’s Consolidated Balance Sheets:

REVENUES
Utilities
Our California Utilities generate revenues primarily from deliveries to their customers of electricity by SDG&E and natural gas by both SoCalGas and SDG&E and from related services. They record these revenues following the accrual method and recognize them upon delivery and performance. They also record revenue from CPUC-approved incentive awards, some of which require approval by the CPUC prior to being recognized. We provide additional discussion on utility incentive mechanisms in Note 14.
On a monthly basis, SoCalGas accrues natural gas storage contract revenues, which consist of storage reservation and variable charges based on negotiated agreements with terms of up to 15 years.
Our natural gas utilities outside of California (Mobile Gas, Willmut Gas and Ecogas) apply U.S. GAAP for regulated utilities consistent with the California Utilities.
Our electric distribution utilities in South America, Chilquinta Energía and Luz del Sur, serve primarily regulated customers, and their revenues are based on tariffs that are set by the National Energy Commission (Comisión Nacional de Energía, or CNE) in Chile and the Energy and Mining Investment Supervisory Body (Organismo Supervisor de la Inversión en Energía y Minería, or OSINERGMIN) of the National Electricity Office under the Ministry of Energy and Mines in Peru.
The tariffs charged are based on an efficient model distribution company defined by Chilean law in the case of Chilquinta Energía, and OSINERGMIN in the case of Luz del Sur. The tariffs include operation and maintenance costs, an internal rate of return on the new replacement value of depreciable assets, charges for the use of transmission systems, and a component for the value added by the distributor. Tariffs are designed to provide for a pass-through to customers of the main noncontrollable cost items (mainly power purchases and transmission charges), recovery of reasonable operating and administrative costs, incentives to reduce costs and make needed capital investments and a regulated rate of return on the distributor’s regulated asset base. Because the tariffs are based on a model and are intended to cover the costs of the model company, but are not based on the costs of the specific utility and may not result in full cost recovery, they do not meet the requirement necessary for treatment under applicable U.S. GAAP for regulatory accounting.
For Chilquinta Energía, rates for four-year periods related to distribution and sub-transmission are reviewed separately on an alternating basis every two years. In late 2011, Chilquinta Energía initiated the process to establish its distribution rates for the period from November 2012 to October 2016. This process was completed in November 2012, with rates published in April 2013, and tariff adjustments going into effect retroactively from November 2012. The next review process for distribution rates is scheduled to be completed, with tariff adjustments also going into effect, in November 2016.
In April 2013, the CNE completed the process to establish Chilquinta Energía’s sub-transmission rates for the period January 2011 to December 2014, with tariff adjustments going into effect retroactively from January 2011. The sub-transmission rates period has been extended for one year, for one time only, to December 2015 due to a change in law issued in December 2014. Accordingly, the next review process for sub-transmission rates will be in January 2016, covering the period from January 2016 to December 2019.
The components of tariffs above for Luz del Sur are reviewed and adjusted every four years. The final distribution rate-setting resolution for the 2013-2017 period was published in October 2013 and went into effect on November 1, 2013.
The table below shows the total utilities revenues in Sempra Energy’s Consolidated Statements of Operations for each of the last three years. The revenues include amounts for services rendered but unbilled (approximately one-half month’s deliveries) at the end of each year.

As we discuss in Note 14, the natural gas supply for SDG&E’s and SoCalGas’ core natural gas customers is purchased by SoCalGas as a combined procurement portfolio managed by SoCalGas. Core customers are primarily residential and small commercial and industrial customers. This core gas procurement function is considered a shared service, therefore amounts related to SDG&E are not included in SoCalGas’ Consolidated Statements of Operations.
We provide additional information concerning utility revenue recognition in “Regulatory Matters” above.
Energy-Related Businesses
Sempra South American Utilities
Sempra South American Utilities generates revenues from energy-services companies that provide electric construction services and recognizes these revenues when services are provided in accordance with contractual agreements. The energy-services company in Chile also generates revenue from selling electricity to non-regulated customers.
Sempra Mexico
Sempra Mexico’s Termoeléctrica de Mexicali natural gas-fired power plant generates revenues from selling electricity and/or capacity to the California Independent System Operator (ISO) and to governmental, public utility and wholesale power marketing entities. Sempra Mexico recognizes these revenues as the electricity is delivered and capacity is provided. Sempra Mexico’s pipeline operations recognize revenues from the sale and transportation of natural gas as deliveries are made and from fixed capacity payments. Sempra Mexico also recognizes revenues from (1) the sale of LNG and natural gas as deliveries are made to counterparties and (2) from reservation and usage fees under terminal capacity agreements, nitrogen injection service agreements and tug service agreements. It reports revenue net of value added taxes in Mexico. Sempra Mexico’s revenues also include net realized gains and losses and the net change in the fair value of unrealized gains and losses on derivative contracts for natural gas.
Sempra Renewables
For consolidated entities, Sempra Renewables generates revenues from the sale of solar power pursuant to power purchase agreements, and recognizes these revenues when the power is delivered. It also generates revenues for the management of certain of its solar and wind project joint ventures.
Sempra Natural Gas
Sempra Natural Gas generates revenues from selling electricity and/or capacity from its Mesquite Power facility to the California ISO and to governmental, public utility and wholesale power marketing entities. Sempra Natural Gas recognizes these revenues as the electricity is delivered and capacity is provided. Related to its LNG terminal, prior to October 1, 2014, the effective date of the Cameron LNG Holdings joint venture, Sempra Natural Gas recognized revenues from reservation and usage fees. We discuss the deconsolidation of Cameron LNG, LLC and related assets further in Note 3. Sempra Natural Gas also records revenues from contractual counterparty obligations for non-delivery of LNG cargoes, as well as revenues from the sale of LNG and natural gas as deliveries are made to counterparties. Sempra Natural Gas recognizes revenue on natural gas storage and transportation operations when services are provided in accordance with contractual agreements for the storage and transportation services. Sempra Natural Gas revenues also include net realized gains and losses and the net change in the fair value of unrealized gains and losses on derivative contracts for power and natural gas.
OTHER COST OF SALES
Other Cost of Sales primarily includes
pipeline capacity costs, and pipeline transportation and natural gas marketing costs incurred at Sempra Natural Gas;
electric construction services costs incurred by Sempra South American Utilities’ energy-services companies; and
energy management service fees at Sempra Mexico.
OPERATION AND MAINTENANCE EXPENSES
Operation and Maintenance includes operating and maintenance costs, and general and administrative costs, consisting primarily of personnel costs, purchased materials and services, litigation expense and rent.
FOREIGN CURRENCY TRANSLATION
Our operations in South America and our natural gas distribution utility in Mexico use their local currency as their functional currency. The assets and liabilities of their foreign operations are translated into U.S. dollars at current exchange rates at the end of the reporting period, and revenues and expenses are translated at average exchange rates for the year. The resulting noncash translation adjustments do not enter into the calculation of earnings or retained earnings (unless the operation is being discontinued), but are reflected in Comprehensive Income and in Accumulated Other Comprehensive Income (Loss), a component of shareholders’ equity.
Currency transaction (losses) gains in a currency other than the entity’s functional currency were $(15) million, $(3) million, and $9 million for the years ended December 31, 2014, 2013, and 2012, respectively, and are included in Other Income, Net, at Sempra Energy
Cash flows of the consolidated foreign subsidiaries are translated into U.S. dollars using average exchange rates for the period. We report the effect of exchange rate changes on cash balances held in foreign currencies in “Effect of Exchange Rate Changes on Cash and Cash Equivalents” on our Consolidated Statements of Cash Flows.
TRANSACTIONS WITH AFFILIATES
Due to and from Unconsolidated Affiliates – Sempra Energy Consolidated
Sempra South American Utilities has a U.S. dollar-denominated loan to Eletrans S.A. to provide project financing for the construction of transmission lines. Eletrans S.A. is an affiliate of Chilquinta Energía that we discuss in Note 4. At December 31, 2014 and 2013, the principal balance outstanding was $40 million and $14 million, plus $1 million and a negligible amount of accumulated interest outstanding, respectively, at a fixed interest rate of 4 percent.
In the second half of 2014, Sempra Mexico made three four-year and one three-year, U.S. dollar-denominated loans to affiliates of Sempra Mexico’s joint venture with Petróleos Mexicanos (or PEMEX, the Mexican state-owned oil company) to finance the Los Ramones Norte pipeline project. At December 31, 2014, these loans have principal balances outstanding aggregating $79 million and $44 million, respectively, plus $2 million of accumulated interest. These loans accrue interest at a variable rate based on a 30-day LIBOR plus 450 basis points (4.66 percent at December 31, 2014).
As we discuss in Note 3, in July 2014, Sempra Mexico sold a 50-percent interest in the first phase of the Energía Sierra Juárez wind project. Upon deconsolidation, the newly formed joint venture repaid a portion, in the amount of $18 million, of a previous intercompany loan from Sempra Mexico to Energía Sierra Juárez. The joint venture assumed the obligation to Sempra Mexico for the remainder of the loan, which has a principal balance outstanding at December 31, 2014 of $21 million plus $1 million of accumulated interest. This loan accrues interest at a variable rate based on a 30-day LIBOR plus 637.5 basis points (6.53 percent at December 31, 2014).
At December 31, 2014 and 2013, Sempra Energy had $38 million and $4 million, respectively, in accounts receivable from various Sempra Renewables and Sempra Mexico joint venture investments. Sempra Energy also had a $2 million contribution payable to Sempra Energy Foundation at December 31, 2014, which was paid in January 2015.
Service Agreements
Sempra Energy, SDG&E and SoCalGas provide certain services to each other and are charged an allocable share of the cost of such services. Also, from time to time, SDG&E and SoCalGas may loan surplus cash to Sempra Energy at interest rates based on one-month commercial paper rates. Amounts due to/from affiliates are as follows:

Transactions with Rockies Express Pipelines LLC
Sempra Natural Gas has an agreement with Rockies Express Pipelines LLC (Rockies Express) for capacity on the Rockies Express pipeline (REX) through November 2019. Sempra Natural Gas recorded cost of sales of $78 million in each of 2014, 2013 and 2012 related to this agreement. We discuss this agreement further in Note 15.
RESTRICTED NET ASSETS
Sempra Energy Consolidated
As we discuss below, the California Utilities have restrictions on the amount of funds that can be transferred to Sempra Energy by dividend, advance or loan as a result of conditions imposed by various regulators. Additionally, certain other Sempra Energy subsidiaries are subject to various financial and other covenants and other restrictions contained in debt and credit agreements (described in Note 5) and in other agreements that limit the amount of funds that can be transferred to Sempra Energy. At December 31, 2014, Sempra Energy was in compliance with all covenants related to its debt agreements.
At December 31, 2014, the amount of restricted net assets of wholly owned subsidiaries of Sempra Energy, including the California Utilities discussed below, that may not be distributed to Sempra Energy in the form of a loan or dividend is $6.6 billion. Additionally, the amount of restricted net assets of our unconsolidated entities is $2.1 billion. Although the restrictions cap the amount of funding that the various operating subsidiaries can provide to Sempra Energy, we do not believe these restrictions will have a significant impact on our ability to access cash to pay dividends.
As we discuss in Note 4, $187 million of Sempra Energy’s consolidated retained earnings balance represents undistributed earnings of equity method investments at December 31, 2014.
California Utilities
The CPUC’s regulation of the California Utilities’ capital structures limits the amounts available for dividends and loans to Sempra Energy. At December 31, 2014, Sempra Energy could have received combined loans and dividends of approximately $640 million from SDG&E and approximately $755 million from SoCalGas.
The payment and amount of future dividends by SDG&E and SoCalGas are at the discretion of their respective boards of directors. The following restrictions limit the amount of retained earnings that may be paid as common stock dividends or loaned to Sempra Energy from either utility:
The CPUC requires that SDG&E’s and SoCalGas’ common equity ratios be no lower than one percentage point below the CPUC-authorized percentage of each entity’s authorized capital structure. The authorized percentage at December 31, 2014 is 52 percent at both SDG&E and SoCalGas.
The FERC requires SDG&E to maintain a common equity ratio of 30 percent or above.
The California Utilities have a combined revolving credit line that requires each utility to maintain a ratio of consolidated indebtedness to consolidated capitalization (as defined in the agreement) of no more than 65 percent, as we discuss in Note 5.
Based on these restrictions, at December 31, 2014, SDG&E’s restricted net assets were $4.3 billion and SoCalGas’ restricted net assets were $2.0 billion, which could not be transferred to Sempra Energy.
Sempra International
Significant restrictions of Sempra International subsidiaries include
Peru and Mexico require domestic corporations to maintain minimum legal reserves as a percentage of capital stock, resulting in restricted net assets of $35 million at Luz del Sur and $81 million at Sempra Energy’s consolidated Mexican subsidiaries at December 31, 2014.
Energía Sierra Juárez, a 50-percent owned and unconsolidated joint venture of Sempra Mexico (see Notes 3 and 4), has a long-term debt agreement that requires the establishment and funding of project and reserve accounts to which the proceeds of loans, letter of credit draws, project revenues and other amounts are deposited and applied in accordance with the debt agreement. The long-term debt agreement also limits the joint venture’s ability to incur liens, incur additional indebtedness, make acquisitions and undertake certain actions. Also, in connection with a debt agreement for the financing of Mexican value added tax, Energía Sierra Juárez had $0.8 million of restricted net assets at December 31, 2014.
Gasoductos de Chihuahua, Sempra Mexico’s joint venture with PEMEX (see Note 4), has a debt agreement that requires the joint venture to maintain a reserve account to pay the debt. Under these restrictions, net assets totaling $32 million are restricted at December 31, 2014.
Sempra U.S. Gas & Power
Significant restrictions of Sempra U.S. Gas & Power subsidiaries include
Wholly owned Copper Mountain Solar 1 has a long-term debt agreement that requires the establishment and funding of project accounts to which the proceeds of loans, project revenues and other amounts are deposited and applied in accordance with the debt agreement. This long-term debt agreement also limits Copper Mountain Solar 1’s ability to incur liens, incur additional indebtedness, make acquisitions and undertake certain actions, while also requiring maintenance of certain debt ratios. Under these restrictions, net assets totaling $9 million are restricted at December 31, 2014.
50-percent owned and unconsolidated joint ventures at Sempra Renewables have debt agreements that require each joint venture to maintain reserve accounts in order to pay the projects’ debt service and operation and maintenance requirements. We discuss Sempra Energy guarantees associated with these requirements in Note 5. At December 31, 2014, as a result of these requirements, there were total restricted net assets at our joint ventures of approximately:
$10 million at Broken Bow 2 Wind
$30 million at California solar partnership
$26 million at Cedar Creek 2 Wind (Cedar Creek 2)
$9 million at Copper Mountain Solar 2
$3 million at Copper Mountain Solar 3
$52 million at Flat Ridge 2 Wind (Flat Ridge 2)
$35 million at Fowler Ridge 2 Wind (Fowler Ridge 2)
$16 million at Mehoopany Wind (Mehoopany Wind)
$94 million at Mesquite Solar 1
Wholly owned Mobile Gas has long-term debt instruments containing restrictions relating to the payment of dividends and other distributions with respect to capital stock. Under these restrictions, net assets of approximately $116 million are restricted at December 31, 2014.
91-percent owned Bay Gas has long-term debt instruments containing restrictions relating to the payment of dividends and other distributions if Bay Gas does not maintain a specified debt service coverage ratio. Bay Gas had no restricted net assets at December 31, 2014.
Sempra Natural Gas has an equity method investment in the Cameron LNG Holdings joint venture, which has debt agreements that require the establishment and funding of project accounts to which the proceeds of loans, project revenues and other amounts are deposited and applied in accordance with the debt agreements. The debt agreements require the joint venture to maintain reserve accounts in order to pay the project debt service, and also contain restrictions related to the payment of dividends and other distributions to the members of the joint venture. We discuss Sempra Energy guarantees associated with Cameron LNG Holdings’ debt agreements in Note 4. Under these restrictions, net assets of Cameron LNG Holdings of approximately $1.8 billion are restricted at December 31, 2014.

Notes to Consolidated Financial Statements [Abstract]
New Accounting Standards	NOTE 2. NEW ACCOUNTING STANDARDS
	We describe below recent pronouncements that have had or may have a significant effect on our financial statements. We do not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to our financial condition, results of operations, cash flows or disclosures.
	SEMPRA ENERGY, SDG&E AND SOCALGAS
	Accounting Standards Update (ASU) 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (ASU 2013-11): ASU 2013-11 provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. If a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purposes, an entity is required to present the unrecognized tax benefit in the financial statements as a liability instead of combined with deferred tax assets.
	We adopted ASU 2013-11 on January 1, 2014 as required and it did not significantly affect our financial condition, results of operations or cash flows.
	ASU 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09): ASU 2014-09 provides accounting guidance for revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers. The guidance also provides a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. This guidance must be adopted using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach.
	We will adopt ASU 2014-09 on January 1, 2017 as required. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

	SEMPRA MEXICO
	In July 2014, Sempra Mexico completed the sale of a 50-percent interest in the 155-MW first phase of its Energía Sierra Juárez wind project to a wholly owned subsidiary of InterGen N.V. for cash proceeds of $24 million, net of $2 million cash sold. Sempra Mexico recognized a pretax gain on the sale of $19 million ($14 million after-tax). The gain on sale included a $7 million after-tax gain attributable to the remeasurement of the retained investment to fair value. Our remaining 50-percent interest in Energía Sierra Juárez is accounted for under the equity method.
	SEMPRA RENEWABLES
	In July 2013, Sempra Renewables formed a joint venture with Consolidated Edison Development (ConEdison Development), a nonrelated party, by selling a 50-percent interest in its 150-MW Copper Mountain Solar 2 solar power facility for $72 million in cash. Sempra Renewables recognized a pretax gain on the sale of $4 million ($2 million after-tax).
	In September 2013, Sempra Renewables formed a joint venture with ConEdison Development by selling a 50-percent interest in its 150-MW Mesquite Solar 1 solar power facility for $103 million in cash. Sempra Renewables recognized a pretax gain on the sale of $36 million ($22 million after-tax).
	In March 2014, Sempra Renewables formed a joint venture with ConEdison Development by selling a 50-percent interest in its 250-MW Copper Mountain Solar 3 solar power facility for $66 million in cash, net of $2 million cash sold. Sempra Renewables recognized a pretax gain on the sale of $27 million ($16 million after-tax).
	In May 2014, Sempra Renewables invested $121 million (as adjusted for financial position at closing) to become a 50-percent partner with ConEdison Development in four solar projects in California. We discuss our investment in the California solar partnership further in Note 4.
	In November 2014, Sempra Renewables formed a joint venture with ConEdison Development by selling a 50-percent interest in the 75-MW Broken Bow 2 Wind project for $58 million in cash. Sempra Renewables recognized a pretax gain on the sale of $14 million ($8 million after-tax). Sempra Renewables acquired the rights to develop the Broken Bow 2 Wind project in September 2013.
	Our remaining 50-percent interests in Copper Mountain Solar 2, Mesquite Solar 1, Copper Mountain Solar 3, and Broken Bow 2 Wind are accounted for under the equity method. Based on the nature of the underlying assets, these investments are considered in-substance real estate. Therefore, in accordance with applicable U.S. GAAP, for each of these investment transactions, the equity method investments were measured at their historical cost and no portion of the gains was attributable to a remeasurement of the retained investments to fair value.
	SEMPRA NATURAL GAS
	Mesquite Power Sale
	In February 2013, Sempra Natural Gas sold one 625-MW block of its 1,250-MW Mesquite Power natural gas-fired power plant in Arizona, including a portion related to common plant, for approximately $371 million in cash to the Salt River Project Agricultural Improvement and Power District (SRP). The asset was classified as held for sale at December 31, 2012 and we recognized a pretax gain on sale of $74 million ($44 million after-tax), included in Gain on Sale of Equity Interests and Assets on our Consolidated Statement of Operations in 2013. In connection with the sale, we entered into a 20-year operations and maintenance agreement with SRP on February 28, 2013, whereby SRP assumed plant operations and maintenance of the facility, including our remaining 625-MW block. We provide additional information concerning the operations and maintenance agreement in Note 15 under “Other Commitments – Sempra Natural Gas.”
	Asset Held For Sale, Power Plant
	We classify assets as held for sale when management approves and commits to a formal plan to actively market an asset for sale and we expect the sale to close within the next twelve months. Upon classifying an asset as held for sale, we record the asset at the lower of its carrying value or its estimated fair value reduced for selling costs, and we stop recording depreciation expense on the asset.
	In January 2014, management approved a formal plan to market and sell the remaining 625-MW block of the Mesquite Power plant, and in October 2014, Sempra Natural Gas entered into a definitive agreement to sell the remaining block of the plant. We anticipate the sale will close in the first half of 2015, subject to obtaining third-party consents for the assignment to the buyer of a 25-year power sales contract associated with the plant.
	At December 31, 2014, the carrying amount of the major classes of assets and related liability held for sale associated with the plant included the following:
	ASSET HELD FOR SALE, POWER PLANT
	(Dollars in millions)
			December 31,

On August 6, 2014, Sempra Natural Gas and its project partners, comprised of affiliates of GDF SUEZ S.A., Mitsui & Co., Ltd., and Mitsubishi Corporation (through a related company jointly established with Nippon Yusen Kabushiki Kaisha), provided their respective final investment decision with regard to the investment in the development, construction and operation of the natural gas liquefaction export facility at the terminal in Hackberry, Louisiana, owned by Cameron LNG, LLC (Cameron LNG). The Cameron liquefaction project utilizes Cameron LNG’s existing facilities, including two marine berths, three LNG storage tanks, and vaporization capability of 1.5 billion cubic feet (Bcf) per day. The current Cameron liquefaction project is comprised of three liquefaction trains and is being designed to a nameplate capacity of 13.5 million tonnes per annum (Mtpa) of LNG, with an expected export capability of 12 Mtpa of LNG, or approximately 1.7 Bcf per day. Commercial operation of all three trains is expected to commence in 2018, with the first year of full operations in 2019. The effective date of the Cameron LNG joint venture, Cameron LNG Holdings, LLC (Cameron LNG Holdings), among Sempra Energy and its project partners occurred on October 1, 2014 after satisfaction of various conditions, including receipt of final regulatory approval and satisfaction of conditions precedent to the first disbursement of the project financing.
Our equity in Cameron LNG Holdings was derived from our contribution of Cameron LNG to the joint venture at its historical carrying value. Each of the partners were issued equity interests in Cameron LNG Holdings in an aggregate of 49.8 percent. Cameron LNG thereby ceased to be wholly owned by Sempra Natural Gas, which retained a 50.2 percent interest in Cameron LNG Holdings. As of the October 1, 2014 effective date, Sempra Natural Gas began to account for its investment in Cameron LNG Holdings under the equity method. Sempra Energy did not recognize a gain or loss related to the contribution of Cameron LNG at cost to the joint venture.
Willmut Gas Company
In May 2012, Sempra Natural Gas acquired 100 percent of the outstanding common stock of Willmut Gas, a regulated natural gas distribution utility with 19,000 customer meters in Hattiesburg, Mississippi. Willmut Gas was purchased for $19 million in cash and the assumption of $10 million of liabilities. Included in the acquisition was $17 million in net property, plant and equipment. As a result of the acquisition, we recorded $10 million of goodwill.

Our share of the undistributed earnings of equity method investments was $187 million and $129 million at December 31, 2014 and 2013, respectively. The December 31, 2014 and 2013 balances do not include remaining distributions of $71 million and $73 million, respectively, associated with our investment in RBS Sempra Commodities LLP (RBS Sempra Commodities) and expected to be received from the partnership as it is dissolved, as we discuss below.
SEMPRA SOUTH AMERICAN UTILITIES
Sempra South American Utilities previously owned 43 percent of two Argentine natural gas utility holding companies, Sodigas Pampeana and Sodigas Sur. In December 2006, we decided to sell these investments and actively pursued their sale since that time. In the first quarter of 2013, we recorded a noncash impairment charge of $10 million ($7 million after-tax) to reduce the carrying value of our investments to estimated fair value at that time. The net charge is reported in Equity Earnings, Net of Income Tax on the Consolidated Statement of Operations for the year ended December 31, 2013. In June 2013, we completed the sale of our Argentine investments for $13 million in cash and recorded an additional $7 million loss ($4 million after-tax) on the sale, which is also included in Equity Earnings, Net of Income Tax.
As a result of the devaluation of the Argentine peso at the end of 2001 and subsequent changes in the value of the peso, Sempra South American Utilities had reduced the carrying value of its investments by a cumulative total of $270 million prior to the sale. These noncash adjustments, based on fluctuations in the value of the Argentine peso, did not affect earnings, but were recorded in Comprehensive Income and Accumulated Other Comprehensive Income (Loss). As a result of the sale of our investments, this cumulative foreign currency translation adjustment was reclassified to Equity Earnings, Net of Income Tax, where it was substantially offset by the elimination of a $250 million accrued liability established in 2006.
In 2013, Chilquinta Energía entered into two 50-percent owned joint ventures, Eletrans S.A. and Eletrans II S.A. (collectively, Eletrans), with Sociedad Austral de Electricidad Sociedad Anónima (SAESA) to construct four transmission lines in Chile. In 2013, Eletrans entered into forward exchange contracts to manage the foreign currency exchange rate risk of the Chilean Unidad de Fomento (CLF) relative to the U.S. dollar, related to certain construction commitments that are denominated in CLF. The forward exchange contracts settle based on anticipated payments to vendors, generally monthly, ending in July 2018. We recorded $4 million of equity losses related to these forward contracts in both 2014 and 2013 in Equity Earnings, Net of Income Tax on the Consolidated Statements of Operations.
SEMPRA MEXICO
Sempra Mexico owns a 50-percent interest in Gasoductos de Chihuahua, a joint venture with Petróleos Mexicanos (or PEMEX, the Mexican state-owned oil company). The joint venture operates several natural gas pipelines and propane systems in Mexico and is developing natural gas pipelines, an ethane transport system and other energy infrastructure. Sempra Mexico acquired its investment in Gasoductos de Chihuahua as part of the purchase of Mexican pipeline and natural gas infrastructure assets in 2010.
In July 2014, Sempra Mexico completed the sale of a 50-percent interest in the 155-MW first phase of its Energía Sierra Juárez wind project to a wholly owned subsidiary of InterGen N.V., as we discuss further in Note 3.
SEMPRA RENEWABLES
With the exception of Copper Mountain Solar 1, which it wholly owns, Sempra Renewables has 50-percent interests in wind and solar energy generation facilities in operation or under construction in Arizona, California, Colorado, Hawaii, Indiana, Kansas, Nebraska, Nevada, and Pennsylvania. The generating capacities of the facilities in operation are contracted under long-term power purchase agreements. These facilities are accounted for under the equity method.
Sempra Renewables formed joint ventures with ConEdison Development by selling 50-percent interests in its Copper Mountain Solar 2 and Mesquite Solar 1 facilities in 2013 and its Copper Mountain Solar 3 and Broken Bow 2 Wind facilities in 2014. We discuss these joint ventures further in Notes 3 and 5.
In May 2014, Sempra Renewables invested $121 million (as adjusted for financial position at closing) to become a 50-percent partner with ConEdison Development in four fully operating solar facilities in California. The joint venture includes ConEdison Development’s CED California Holdings, LLC portfolio, which consists of the 50-MW Alpaugh 50, the 20-MW Alpaugh North and the 20-MW White River 1 facilities in Tulare County, and the 20-MW Corcoran 1 facility in Kings County (collectively, the California solar partnership). The renewable power from all of the projects has been sold under long-term contracts.
SEMPRA NATURAL GAS
Rockies Express
Sempra Natural Gas owns a 25-percent interest in Rockies Express, a partnership that operates a natural gas pipeline, REX, that links the Rocky Mountain region to the upper Midwest and the eastern United States. In November 2012, Kinder Morgan Energy Partners L.P. (KMP) sold its 50-percent interest in Rockies Express, as part of a larger asset group, to Tallgrass Energy Partners, L.P. (Tallgrass). Phillips 66 owns the remaining 25-percent interest. Our total investment in Rockies Express is accounted for as an equity method investment.
The general partner of KMP was Kinder Morgan, Inc. (KMI). As a condition of KMI receiving antitrust approval from the Federal Trade Commission (FTC) for its acquisition of El Paso Corporation, KMI agreed to divest certain assets in its natural gas pipeline group. Included in the asset group, as noted above, was KMP’s interest in Rockies Express. KMP recorded remeasurement losses during 2012 associated with these operations (classified as discontinued operations by KMP). In 2012, we recorded impairments of our partnership investment in Rockies Express of $300 million ($179 million after-tax) and $100 million ($60 million after-tax) in the second and third quarters, respectively, which are included in Equity Earnings (Losses), Before Income Tax on the Consolidated Statement of Operations. Our remaining carrying value in Rockies Express at December 31, 2014 is $340 million. We recorded the write-downs in 2012 as a result of our estimate of fair value for our investment at the reporting date and our conclusion that the impairments were other-than-temporary, as required by U.S. GAAP. We discuss the fair value measurement of our investment in Rockies Express in Note 10.
For income tax purposes, upon KMP’s sale of its 50-percent interest in Rockies Express, the partnership was considered terminated under federal tax law and a new partnership immediately formed which triggered a restart of depreciation method on the partnership’s remaining tax basis of its tangible assets. As required by the LLC agreement, KMP made a cash make-whole payment to Sempra Natural Gas of $41 million in November 2012, which was recorded as equity income from Rockies Express.
Cameron LNG
October 1, 2014 was the effective date of the formation of a joint venture partnership among Sempra Energy and three project partners involving Sempra Natural Gas' Cameron LNG facility in Louisiana, as we discuss in Note 3. As of October 1, 2014, Sempra Natural Gas began accounting for its investment in Cameron LNG Holdings under the equity method.
Cameron LNG Holdings Joint Venture Financing
General. On August 6, 2014, Cameron LNG entered into finance documents (collectively, Loan Facility Agreements) for senior secured financing in an initial aggregate principal amount of up to $7.4 billion under three debt facilities provided by the Japan Bank for International Cooperation (JBIC) and 29 international commercial banks, some of which will benefit from insurance coverage provided by Nippon Export and Investment Insurance (NEXI).
The Cameron LNG Loan Facility Agreements and related finance documents provide senior secured term loans with a maturity date of July 15, 2030. The proceeds of the loans will be used for financing the cost of development and construction of the three-train Cameron LNG project. The Loan Facility Agreements and related finance documents contain customary representations and affirmative and negative covenants for project finance facilities of this kind with the lenders of the type participating in the Cameron LNG financing.
On August 6, 2014, Sempra Energy entered into a completion agreement in favor of HSBC Bank USA, National Association, as security trustee for the benefit of all of Cameron LNG Holdings’ creditors under the Loan Facility Agreements. Pursuant to this completion agreement, Sempra Energy has severally guaranteed 50.2 percent of Cameron LNG Holdings’ senior debt obligations under the Loan Facility Agreements, or a maximum principal amount of $3.7 billion. Completion guarantees for the remaining 49.8 percent of Cameron LNG Holdings’ senior secured financing have been provided by the other project partners. The occurrence of the effectiveness of the Cameron LNG Holdings joint venture on October 1, 2014, as further described in Note 3, was a condition precedent to first disbursement of funds under the Loan Facility Agreements. The Sempra Energy completion guarantee of 50.2 percent of the Cameron LNG Holdings financing also became effective upon effectiveness of the Cameron LNG Holdings joint venture. Sempra Energy’s completion agreement and guarantee will terminate upon financial completion of the three-train Cameron LNG project, which is subject to satisfaction of certain conditions, including all three trains achieving commercial operations and meeting certain operational performance tests. Financial completion is scheduled for the second half of 2019. Sempra Energy recorded a liability of $82 million on October 1, 2014 for the fair value of its obligations associated with the debt reserve account requirements, which constitute guarantees. This liability is being amortized over the duration of the guarantees using the straight-line method.
On August 6, 2014, Sempra Energy and the other project partners entered into a transfer restrictions agreement with Société Générale, as intercreditor agent for the lenders under the Loan Facility Agreements. Pursuant to the transfer restriction agreement, Sempra Energy agreed to certain restrictions on its ability to dispose of Sempra Energy’s indirect fully diluted economic and beneficial ownership interests in Cameron LNG. These restrictions vary over time. Prior to financial completion of the three-train Cameron LNG project, Sempra Energy must retain 37.65 percent of such interest in Cameron LNG. Starting six months after financial completion of the three-train Cameron LNG project, Sempra Energy must retain at least 10 percent of the indirect fully diluted economic and beneficial ownership interest in Cameron LNG. At all times, the Sempra Energy affiliate that is the direct member in the Cameron LNG joint venture must be controlled by Sempra Energy and must have direct ownership of 50.2 percent of the Cameron LNG joint venture.
Interest. The weighted average all-in cost of the loans outstanding under all the Loan Facility Agreements (and based on certain assumptions as to timing of drawdown) is 1.59 percent per annum over LIBOR prior to financial completion of the project and 1.78 percent per annum over LIBOR following financial completion of the project. The Loan Facility Agreements require Cameron LNG to hedge 50 percent of outstanding borrowings to fix the interest rate, beginning in 2016. The hedges are to remain in place until the debt principal has been amortized by 50 percent. In November 2014, Cameron LNG entered into floating-to-fixed interest rate swaps for approximately $3.7 billion notional amount, resulting in an effective fixed rate of 3.19 percent.
Mandatory Prepayments. Cameron LNG Holdings must make mandatory prepayments of all loans made under the Loan Facility Agreements under certain circumstances, including: upon receipt of certain insurance proceeds and expropriation compensation; upon receipt of certain performance liquidated damages under Cameron LNG’s engineering, procurement and construction contract for the liquefaction terminal; in connection with the loss of its tolling agreements or export permits that result in a reduction of Cameron LNG’s debt service coverage ratios below a specified threshold; if it becomes unlawful in any applicable jurisdiction for a lender to fund or maintain its loans; or in connection with any mandatory prepayment of senior notes outstanding (if any).
The loans under the NEXI Covered Loan Facility Agreement and the loans held by JBIC under the JBIC Loan Facility Agreement are subject to certain additional mandatory prepayments that would be triggered if the Japanese sponsors fail to maintain certain ownership interests in Cameron LNG, if Cameron LNG’s Japanese tolling customers do not hold commitments for a certain quantum of nameplate capacity at the liquefaction terminal or if the aggregate annual contracted LNG commitments by Cameron LNG’s tolling customers to Japanese LNG buyers fall below a certain minimum threshold under certain circumstances.
Events of Default. Cameron LNG’s Loan Facility Agreements and related finance documents also contain events of default customary for such financings, including events of default for: failure to pay principal and interest on the due date; insolvency of Cameron LNG; abandonment of the project; expropriation; unenforceability or termination of the finance documents; and a failure to achieve financial completion of the project by a financial completion deadline date of September 30, 2021 (with up to additional 365 days extension beyond such date permitted in cases of force majeure). A delay in construction that results in a failure to achieve financial completion of the project by this financial completion deadline date would therefore result in an event of default under Cameron LNG’s financing and a potential demand on Sempra Energy’s guarantees.
Security. To support Cameron LNG’s obligations under the Loan Facility Agreements and related finance documents, Cameron LNG has granted security over all of its assets, subject to customary exceptions, and all equity interests in Cameron LNG have been pledged to HSBC Bank USA, National Association, as security trustee for the benefit of all Cameron LNG’s creditors. As a result, an enforcement action by the lenders taken in accordance with the finance documents could result in the exercise of such security interests by the lenders and the loss of ownership interests in Cameron LNG by Sempra Energy and the other project partners.
The security trustee under Cameron LNG’s financing can demand that a payment be made by Sempra Energy under its guarantees of Sempra Energy’s 50.2 percent share of senior debt obligations due and payable either on the date such amounts were due from Cameron LNG (taking into account cure periods) in the event of a failure by Cameron LNG to pay such senior debt obligations when they become due or within 10 business days in the event of an acceleration of senior debt obligations under the terms of the finance documents. If an event of default occurs under the Sempra Energy completion agreement, the security trustee can demand that Sempra Energy purchase its 50.2 percent share of all then outstanding senior debt obligations within five business days (other than in the case of a bankruptcy default, which is automatic).
RBS SEMPRA COMMODITIES
RBS Sempra Commodities is a United Kingdom limited liability partnership formed by Sempra Energy and The Royal Bank of Scotland plc (RBS) in 2008 to own and operate the commodities-marketing businesses previously operated through wholly owned subsidiaries of Sempra Energy. We and RBS sold substantially all of the partnership’s businesses and assets in four separate transactions completed in 2010 and 2011. We account for our investment in RBS Sempra Commodities under the equity method, and report miscellaneous costs since the sale of the business in Parent and Other.
We recorded $2 million and $3 million in pretax equity losses for the years ended December 31, 2014 and 2013, respectively, and no equity earnings or losses for the year ended December 31, 2012.
In April 2011, we and RBS entered into a letter agreement (Letter Agreement) which amended certain provisions of the agreements that formed RBS Sempra Commodities. The Letter Agreement addresses the wind-down of the partnership and the distribution of the partnership’s remaining assets. In accordance with the Letter Agreement, we received distributions of $50 million in 2013. The investment balance of $71 million at December 31, 2014 reflects remaining distributions expected to be received from the partnership in accordance with the Letter Agreement. The timing and amount of distributions may be impacted by the matters we discuss related to RBS Sempra Commodities in Note 15 under “Other Litigation.” In addition, amounts may be retained by the partnership for an extended period of time to help offset unanticipated future general and administrative costs necessary to complete the dissolution of the partnership.
In connection with the Letter Agreement described above, we also released RBS from its indemnification obligations with respect to items for which J.P. Morgan Chase & Co. (JP Morgan), one of the buyers of the partnership’s businesses, has agreed to indemnify us.

Notes to Consolidated Financial Statements [Abstract]
Debt and Credit Facilities	NOTE 5. DEBT AND CREDIT FACILITIES
	LINES OF CREDIT
	At December 31, 2014, Sempra Energy Consolidated had an aggregate of $4.1 billion in three primary committed lines of credit for Sempra Energy, Sempra Global and the California Utilities to provide liquidity and to support commercial paper, the major components of which we detail below. Available unused credit on these lines at December 31, 2014 was $2.4 billion. Some of Sempra Energy’s subsidiaries, primarily our foreign operations, have additional general purpose credit facilities, aggregating $865 million at December 31, 2014. Available unused credit on these lines totaled $536 million at December 31, 2014.
	Sempra Energy
	Sempra Energy has a $1.067 billion, five-year syndicated revolving credit agreement expiring in March 2017. Citibank, N.A. serves as administrative agent for the syndicate of 24 lenders. No single lender has greater than a 7-percent share.
	Borrowings bear interest at benchmark rates plus a margin that varies with market index rates and Sempra Energy’s credit ratings. The facility requires Sempra Energy to maintain a ratio of total indebtedness to total capitalization (as defined in the agreement) of no more than 65 percent at the end of each quarter. At December 31, 2014 and 2013, Sempra Energy was in compliance with this and all other financial covenants under the credit facility. The facility also provides for issuance of up to $635 million of letters of credit on behalf of Sempra Energy with the amount of borrowings otherwise available under the facility reduced by the amount of outstanding letters of credit.
	At December 31, 2014, Sempra Energy had no outstanding borrowings or letters of credit supported by the facility.
	Sempra Global
	Sempra Global has a $2.189 billion, five-year syndicated revolving credit agreement expiring in March 2017. Citibank, N.A. serves as administrative agent for the syndicate of 25 lenders. No single lender has greater than a 7-percent share.
	Sempra Energy guarantees Sempra Global’s obligations under the credit facility. Borrowings bear interest at benchmark rates plus a margin that varies with market index rates and Sempra Energy’s credit ratings. The facility requires Sempra Energy to maintain a ratio of total indebtedness to total capitalization (as defined in the agreement) of no more than 65 percent at the end of each quarter. At December 31, 2014 and 2013, Sempra Energy was in compliance with this and all other financial covenants under the credit facility.
	At December 31, 2014, Sempra Global had $1.3 billion of commercial paper outstanding supported by the facility. At December 31, 2013, Sempra Global had $200 million of commercial paper outstanding classified as long-term debt based on management’s intent and ability to maintain this level of borrowing on a long-term basis either supported by this credit facility or by issuing long-term debt. This classification has no impact on cash flows.
	California Utilities
	SDG&E and SoCalGas have a combined $877 million, five-year syndicated revolving credit agreement expiring in March 2017. JPMorgan Chase Bank, N.A. serves as administrative agent for the syndicate of 24 lenders. No single lender has greater than a 7-percent share. The agreement permits each utility to individually borrow up to $658 million, subject to a combined limit of $877 million for both utilities. It also provides for the issuance of letters of credit on behalf of each utility subject to a combined letter of credit commitment of $300 million for both utilities. The amount of borrowings otherwise available under the facility is reduced by the amount of outstanding letters of credit.
	Borrowings under the facility bear interest at benchmark rates plus a margin that varies with market index rates and the borrowing utility’s credit ratings. The agreement requires each utility to maintain a ratio of total indebtedness to total capitalization (as defined in the agreement) of no more than 65 percent at the end of each quarter. At December 31, 2014 and 2013, the California Utilities were in compliance with this and all other financial covenants under the credit facility.
	Each utility’s obligations under the agreement are individual obligations, and a default by one utility would not constitute a default by the other utility or preclude borrowings by, or the issuance of letters of credit on behalf of, the other utility.
	At December 31, 2014, SDG&E and SoCalGas had $346 million and $50 million of commercial paper outstanding supported by the facility. Available unused credit on the line at December 31, 2014 was $312 million and $481 million at SDG&E and SoCalGas, respectively. SoCalGas’ availability reflects the impact of SDG&E’s use as of December 31, 2014 of the combined credit available on the line.
	Sempra Mexico
	In June 2014, IEnova entered into an agreement for a $200 million, U.S. dollar-denominated, three-year corporate revolving credit facility to finance working capital and for general corporate purposes. The lender is Banco Santander, (México), S.A., Institución de Banca Múltiple, Grupo Financiero Santander Mexico. At December 31, 2014, IEnova had $145 million of outstanding borrowings supported by the facility, and available unused credit on the line was $55 million.
	In August 2014, IEnova entered into an agreement for a $100 million, U.S. dollar-denominated, three-year corporate revolving credit facility to finance working capital and for general corporate purposes. The lender is Sumitomo Mitsui Banking Corporation. At December 31, 2014, IEnova had $51 million of outstanding borrowings supported by the facility, and available unused credit on the line was $49 million.
	GUARANTEES
	Sempra Renewables
	Sempra Renewables and BP Wind Energy each currently hold 50-percent interests in Flat Ridge 2. The project obtained construction financing in December 2012, and proceeds from the loans were used to return $148 million of each owner’s joint venture investment in 2012. In March 2013, the construction financing was converted into permanent financing consisting of a term loan and a fixed-rate note. The term loan of $242 million expires in June 2023 and the fixed rate note of $110 million expires in June 2035. The financing agreement requires Sempra Renewables and BP Wind Energy, severally for each partner’s 50-percent interest, to return cash to the project in the event that the project does not meet certain cash flow criteria or in the event that the project’s debt service, operation and maintenance and firm transmission and production tax credits reserve accounts are not maintained at specific thresholds. Sempra Renewables recorded a liability of $3 million in 2013 for the fair value of its obligations associated with the cash flow requirements, which constitutes a guarantee. The liability is being amortized over its expected life. The outstanding loans are not guaranteed by the partners.
	Sempra Renewables and BP Wind Energy each currently hold 50-percent interests in Mehoopany Wind. The project obtained construction financing in June 2012, and proceeds from the loans were used to return $13 million and $17 million of each owner’s joint venture investment in 2013 and 2012, respectively. In May 2013, the construction financing was converted into permanent financing consisting of a term loan. The term loan of $162 million expires in May 2031. The financing agreement requires Sempra Renewables and BP Wind Energy, severally for each partner’s 50-percent interest, to return cash to the project in the event that the project does not meet certain cash flow criteria or in the event that the project’s debt service, operation and maintenance and production tax credits reserve accounts are not maintained at specific thresholds. Additionally, in conjunction with the term loan conversion, Sempra Renewables and BP Wind Energy have provided guarantees to the lenders in lieu of Mehoopany Wind funding a reserve account requirement. Sempra Renewables recorded liabilities of $11 million in 2013 for the fair value of its obligations associated with the cash flow and reserve account requirements, which constitute guarantees. The liabilities are being amortized over their expected lives. The outstanding loans are not guaranteed by the partners.
	Sempra Natural Gas
	Sempra Energy entered into completion guarantees related to the financing of the Cameron LNG project, as we discuss in Note 4.

FIRST MORTGAGE BONDS
The California Utilities issue first mortgage bonds secured by a lien on utility plant. The California Utilities may issue additional first mortgage bonds upon compliance with the provisions of their bond agreements (indentures). These indentures require, among other things, the satisfaction of pro forma earnings-coverage tests on first mortgage bond interest and the availability of sufficient mortgaged property to support the additional bonds, after giving effect to prior bond redemptions. The most restrictive of these tests (the property test) would permit the issuance, subject to CPUC authorization, of an additional $4.3 billion of first mortgage bonds at SDG&E and $0.9 billion at SoCalGas at December 31, 2014.
In September 2014, SoCalGas publicly offered and sold $500 million of 3.15-percent first mortgage bonds maturing in 2024. SoCalGas used the proceeds from this offering for the repayment of commercial paper and other general corporate purposes.
In March 2014, SoCalGas publicly offered and sold $250 million of 4.45-percent first mortgage bonds maturing in 2044. SoCalGas used the proceeds from this offering for the repayment of its 5.5-percent first mortgage bonds that matured in March 2014.
INDUSTRIAL DEVELOPMENT BONDS
Sempra Natural Gas
To secure an approved exemption from sales and use tax, Sempra Natural Gas has incurred through December 31, 2014, $257 million ($3 million in 2013, $53 million in 2012, $84 million in 2011, $42 million in 2010 and $75 million in 2009) out of a maximum available $265 million of long-term debt related to the construction and equipping of its Mississippi Hub natural gas storage facility. After a redemption of $180 million in December 2011, the debt balance remaining at December 31, 2014 is $77 million. The debt is payable to the Mississippi Business Finance Corporation (MBFC), and we recorded bonds receivable from the MBFC for the same amount. Both the financing obligation and the bonds receivable have interest rates of 4.5 percent and are due on July 1, 2024.
OTHER LONG-TERM DEBT
Sempra Energy
In June 2014, Sempra Energy publicly offered and sold $500 million of 3.55-percent, fixed rate notes maturing in 2024. Sempra Energy used the proceeds from this offering for the repayment of commercial paper.

Sempra Mexico
In June 2014, Energía Sierra Juárez entered into a $240 million loan to project finance the construction of the wind project. The variable rate loan is secured by the project and will convert to an 18-year term loan upon completion of the first phase of the project. To partially moderate its exposure to interest rate changes associated with the term loan, Energía Sierra Juárez entered into floating-to-fixed interest rate swaps for 90 percent of the loan amount, which will result in an effective fixed rate of 6.1 percent. The swap is effective on the conversion to a term loan. The remaining 10 percent of principal bears interest at rates varying with market rates (0.16 percent at December 31, 2014). The loan agreement also provides for a $31.7 million letter of credit facility. Energía Sierra Juárez also entered into a separate, Peso-denominated credit facility for up to $35 million U.S. dollar equivalent to fund the value added tax of the project. On June 12, 2014, Energía Sierra Juárez drew down $82 million of the construction loan. On July 16, 2014, this $82 million of long-term debt and the related swaps were deconsolidated upon the sale of a 50-percent interest in Energía Sierra Juárez, as we discuss in Note 3.
Sempra Renewables
On October 30, 2014, Sempra Renewables completed a private offering of an aggregate of $72 million in principal amount of 4.82-percent fixed rate notes maturing in 2039. Proceeds from this offering were used to finance its Broken Bow 2 Wind project. On November 5, 2014, this $72 million of long-term debt was deconsolidated upon the sale of a 50-percent interest in Broken Bow 2 Wind to ConEdison Development, which we discuss in Note 3.
On March 6, 2014, Sempra Renewables entered into a $356 million construction loan to finance its Copper Mountain Solar 3 project. The loan is secured by the project and will convert to a 10-year term loan upon completion of the project. To partially moderate its exposure to interest rate changes, Copper Mountain Solar 3 entered into floating-to-fixed interest rate swaps for 75 percent of the loan amount, resulting in an effective fixed rate of 5.35 percent. The remaining 25 percent bears interest at rates varying with market rates (0.16 percent at December 31, 2014). In connection with the loan agreement, Copper Mountain Solar 3 may also utilize up to $72 million under a letter of credit facility, which may be used to meet project collateral requirements and debt service reserve requirements. On March 6, 2014, Copper Mountain Solar 3 drew down $97 million from the loan. On March 13, 2014, this $97 million of long-term debt and the related swaps were deconsolidated upon the sale of a 50-percent interest in Copper Mountain Solar 3, as we discuss in Note 3.

	In 2014, 2013 and 2012, non-U.S. earnings taxed at lower statutory income tax rates than the U.S. are primarily related to operations in Mexico, Chile and Peru.
	In 2014, our effective income tax rate was affected by a $25 million tax benefit due to the release of a Louisiana valuation allowance against a deferred tax asset associated with Cameron LNG developments. This benefit is included in “State Income Taxes, Net of Federal Income Tax Benefit” in the table above.
	In addition, the effective income tax rates for Sempra Energy Consolidated and SDG&E were impacted in 2014 by a $17 million charge to reduce certain tax regulatory assets attributed to SDG&E’s investment in SONGS pursuant to a settlement agreement to resolve the CPUC’s Order Instituting Investigation (OII) into the SONGS outage that we discuss in Note 13.
	Foreign exchange and inflation effects for Sempra Energy Consolidated in 2014 are primarily due to significant devaluation of the Mexican peso against the U.S. dollar in 2014.
	In 2013, our effective income tax rate was affected by $63 million of income tax expense recorded in the first quarter of 2013 resulting from a corporate reorganization in connection with the IEnova stock offerings.
	Utility repairs expenditures significantly affecting the effective income tax rates for Sempra Energy Consolidated, SDG&E and SoCalGas in 2014, 2013 and 2012 are due to a change in 2012 in the income tax treatment of certain repairs that are capitalized for financial statement purposes. The change in income tax treatment of certain repairs for electric transmission and distribution assets, which applied to SDG&E, was made pursuant to an Internal Revenue Service (IRS) Revenue Procedure providing a safe harbor for deducting certain repairs expenditures from taxable income when incurred for tax years beginning on or after January 1, 2011. The change in income tax treatment of certain repairs expenditures for gas plant assets, which applied to SoCalGas, was made pursuant to an IRS Revenue Procedure, which allows, under an Internal Revenue Code section, such expenditures to be deducted from taxable income when incurred.
	Life insurance contracts significantly affected the effective tax rate for Sempra Energy Consolidated in 2012 primarily due to our decision in the second quarter of 2012 to hold life insurance contracts kept in support of certain benefit plans to term. Previously, we took the position that we might cash in or sell these contracts before maturity, which required that we record deferred income taxes on unrealized gains on investments held within the insurance contracts.
	In September 2013, the IRS and U.S. Department of the Treasury released final tangible property regulations on the capitalization and expensing rules applicable to expenditures for the acquisition and production of tangible property. Companies were required to conform their tax accounting methods and elect any safe harbors under the final regulations no later than the tax year beginning on January 1, 2014. Additionally, if a change in the company’s tax accounting methods was required to conform to the final regulations, the company was also required to adjust its deferred tax balances at December 31, 2013 for any tax adjustments required to bring all prior periods into compliance with the final regulations. We evaluated our tax accounting methods and deferred tax balances based on the guidance contained in the final tangible property regulations and determined that we are following the guidance in all material respects. Any adjustments to deferred taxes resulting from changes to comply with the final tangible property regulations would have a de minimis impact on the financial statements. Accordingly, we did not make any adjustment to our deferred tax balances at December 31, 2014 or December 31, 2013 based on the issuance of the final tangible property regulations.
	For SDG&E and SoCalGas, the CPUC requires flow-through rate-making treatment for the current income tax benefit or expense arising from certain property-related and other temporary differences between the treatment for financial reporting and income tax, which will reverse over time. Under the regulatory accounting treatment required for these flow-through temporary differences, deferred income tax assets and liabilities are not recorded to deferred income tax expense, but rather to a regulatory asset or liability, which results in impacting the current effective income tax rate. As a result, changes in the relative size of these items compared to pretax income, from period to period, can cause variations in the effective income tax rate. The following items are subject to flow-through treatment:
	repairs expenditures related to a certain portion of utility plant fixed assets
	the equity portion of AFUDC
	a portion of the cost of removal of utility plant assets
	self-developed software expenditures
	depreciation on a certain portion of utility plant assets
	The AFUDC related to equity recorded for regulated construction projects at Sempra Mexico and Sempra Natural Gas has similar flow-through treatment.
	We use the deferral method for investment tax credits (ITC). For certain solar and wind generating assets placed into service during 2012, we elected to seek cash grants rather than ITC for which the projects also qualify. Accordingly, cash grant accounting was applied. Grant accounting for cash grants is very similar to the deferral method of accounting for ITC, the primary difference being the recording of a cash grant receivable instead of an income tax receivable.
	Under the deferral method of accounting for ITC and under grant accounting for cash grants, we record a deferred income tax benefit, on day one, which is reflected in income tax expense by recording a deferred income tax asset during the year the renewable energy assets are placed in service. This deferred income tax asset results from the day-one difference in the income tax basis and financial statement basis of the renewable energy assets, referred to as the day-one basis difference. The financial statement basis of the assets is reduced by 100 percent of the ITC or grant expected; U.S. federal income tax basis is reduced by only 50 percent for both ITC and grants; and state income tax basis is reduced by 50 percent for grants and not at all for ITC.
	Conversion of ITC to cash is generally dependent on reducing income tax payments and thus the existence of a U.S. federal net operating loss (NOL) carryforward can result in delaying this conversion.

At December 31, 2014, Sempra Energy has recorded a valuation allowance against a portion of its total deferred income tax assets, as shown above in the “Deferred Income Taxes for Sempra Energy Consolidated” table. A valuation allowance is recorded when, based on more-likely-than-not criteria, negative evidence outweighs positive evidence with regard to our ability to realize a deferred income tax asset in the future. Of the valuation allowances recorded to date, the negative evidence outweighs the positive evidence primarily due to cumulative pretax losses in various U.S. state and non-U.S. jurisdictions resulting in a deferred income tax asset related to NOLs, as discussed below, that we currently do not believe will be realized on a more-likely-than-not basis. At both Sempra Energy and SDG&E, deferred income taxes for variable interest entities are shown on a net basis. Therefore, valuation allowances of $48 million at December 31, 2014 and $60 million at December 31, 2013 related to variable interest entities are not reflected in the table above. Of Sempra Energy’s total valuation allowance of $39 million at December 31, 2014, $8 million is related to non-U.S. NOLs and $31 million to U.S. state NOLs. Of Sempra Energy’s total valuation allowance of $96 million at December 31, 2013, $12 million is related to non U.S. NOLs and $84 million to U.S. state NOLs. The total valuation allowance decreased in 2014 primarily due to release of a Louisiana valuation allowance against a deferred tax asset associated with Cameron LNG developments and expiration of the carryover periods of certain U.S. state and non-U.S. NOLs.
Sempra Energy’s U.S. subsidiaries had $4.9 billion of unused U.S. federal consolidated NOLs that will begin to expire in 2031, $182 million of unused U.S. federal consolidated general business tax credits that will begin to expire in 2032 and $52 million of unused foreign tax credits that expire in 2024. Included in the NOL amount is $266 million of excess tax deductions related to employee stock expense for which a benefit will be recorded to additional paid in capital when realized. When assessing whether a tax benefit relating to employee stock expense has been realized, we follow the tax law ordering method, under which current year share-based compensation deductions are assumed to be utilized before net operating loss carryforwards and other tax attributes. We have recorded deferred income tax benefits on these NOLs, and tax credits, in total, because we currently believe they will be realized on a more-likely-than-not basis.
At December 31, 2014, SDG&E had $867 million of unused U.S. federal NOL which expires in 2032 and $12 million of unused U.S. federal general business tax credits which begin to expire in 2031. At December 31, 2014, SoCalGas had $210 million of unused U.S. federal NOLs which begin to expire in 2032 and $11 million of unused U.S. federal general business tax credits which begin to expire in 2031. We have recorded deferred income tax benefits on these NOLs and tax credits, in total, because we currently believe they will be realized on a more-likely-than-not basis.
Sempra Energy’s U.S. subsidiaries had $2.7 billion of unused U.S. state NOLs, primarily in Alabama, California, Connecticut, District of Columbia, Indiana, Kansas, Louisiana, Minnesota, Missouri, Mississippi, Nebraska and Pennsylvania. These U.S. state NOLs expire between 2015 and 2034. We have not recorded deferred income tax benefits on a portion of Sempra Energy’s total U.S. state NOLs because we currently believe they will not be realized on a more-likely-than-not basis, as discussed above. Sempra Natural Gas and its project partners are currently developing a natural gas liquefaction export facility at the Cameron LNG terminal in Louisiana. In 2014 we released $25 million of a Louisiana valuation allowance against a deferred tax asset associated with Cameron LNG developments. Sempra Energy’s U.S. subsidiaries also had $31 million of unused U.S. state general business tax credits that begin to expire in 2016. We have recorded deferred income tax benefits on these tax credits, in total, because we currently believe they will be realized on a more-likely-than-not basis.
At December 31, 2014, Sempra Energy’s non-U.S. subsidiaries had $312 million of unused NOLs available to utilize in the future to reduce Sempra Energy’s future non-U.S. income tax expense related to our companies in Mexico and the Netherlands. The carryforward periods for our non-U.S. unused NOLs expire between 2015 and 2024. We have not recorded deferred income tax benefits on a portion of Sempra Energy’s total non-U.S. NOLs because we currently believe they will not be realized on a more-likely-than-not basis, as discussed above.
At December 31, 2014, Sempra Energy had not recognized a U.S. deferred income tax liability related to a $3.6 billion basis difference between its financial statement and income tax investment amount in its non-U.S. subsidiaries and non-U.S. corporate joint ventures. This basis difference consists of $3.6 billion of cumulative undistributed earnings that we expect to reinvest indefinitely outside of the U.S. These cumulative undistributed earnings have previously been reinvested or will be reinvested in active non-U.S. operations, thus we do not intend to use these earnings as a source of funding for U.S. operations. It is not practical to determine the hypothetical unrecognized amount of U.S. deferred income taxes that might be payable if the cumulative undistributed earnings were eventually distributed or the investments were sold.
Following is a summary of unrecognized income tax benefits:

INCOME TAX AUDITS
Sempra Energy is subject to U.S. federal income tax as well as to income tax of multiple state and non-U.S. jurisdictions. We remain subject to examination for U.S. federal tax years after 2010. We are subject to examination by major state tax jurisdictions for tax years after 2008. Certain major non-U.S. income tax returns for tax years 2008 through the present are open to examination.
In addition, we intend to file federal refund claims for the 2009 and 2010 tax years during the first half of 2015; however, no additional tax may be assessed by the Internal Revenue Service for pre-2011 tax years. We have also filed state refund claims for tax years back to 1998. The pre-2009 tax years for our major state tax jurisdictions are closed to new issues; therefore, no additional tax may be assessed by the taxing authorities for these tax years.
SDG&E and SoCalGas are subject to U.S. federal income tax as well as income tax of state jurisdictions. They remain subject to examination for U.S. federal tax years after 2010 and by major state tax jurisdictions for tax years after 2008.

EMPLOYEE_BENEFIT_PLANS

EMPLOYEE BENEFIT PLANS	12 Months Ended
	Dec. 31, 2014
Notes to Consolidated Financial Statements [Abstract]
Employee Benefit Plans	NOTE 7. EMPLOYEE BENEFIT PLANS
	We are required by applicable U.S. GAAP to:
	recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status in the statement of financial position;
	measure a plan’s assets and its obligations that determine its funded status as of the end of the fiscal year (with limited exceptions); and
	recognize changes in the funded status of pension and other postretirement benefit plans in the year in which the changes occur. Generally, those changes are reported in other comprehensive income and as a separate component of shareholders’ equity.
	The detailed information presented below covers the employee benefit plans of Sempra Energy and its principal subsidiaries.
	Sempra Energy has funded and unfunded noncontributory traditional defined benefit and cash balance plans, including separate plans for SDG&E and SoCalGas, which collectively cover all eligible employees, including members of the Sempra Energy board of directors who were participants in a predecessor plan on or before June 1, 1998. Pension benefits under the traditional defined benefit plans are based on service and final average pay, while the cash balance plans provide benefits using a career average earnings methodology.
	Chilquinta Energía has an unfunded contributory defined benefit plan covering all employees hired before October 1, 1981 and an unfunded noncontributory termination indemnity obligation covering all employees. The plans generally provide defined benefits to retirees based on date of hire, years of service and final average salary.
	Sempra Energy also has other postretirement benefit plans (PBOP), including separate plans for SDG&E and SoCalGas, which collectively cover all domestic (except Willmut Gas) and certain foreign employees. The life insurance plans are both contributory and noncontributory, and the health care plans are contributory. Participants’ contributions are adjusted annually. Other postretirement benefits include medical benefits for retirees’ spouses.
	Chilquinta Energía also has two noncontributory postretirement benefit plans which cover substantially all employees – a health care plan and an energy subsidy plan that provides for reduced energy rates. The health care plan includes benefits for retirees’ spouses and dependents.
	Pension and other postretirement benefits costs and obligations are dependent on assumptions used in calculating such amounts. These assumptions include
	discount rates
	expected return on plan assets
	health care cost trend rates
	mortality rates
	rate of compensation increases
	termination and retirement rates
	utilization of postretirement welfare benefits
	payout elections (lump sum or annuity)
	lump sum interest rates
	We review these assumptions on an annual basis prior to the beginning of each year and update them as appropriate. We consider current market conditions, including interest rates, in making these assumptions. New mortality table studies were released by the Society of Actuaries during 2014 that significantly increased life expectancy assumptions, and we have incorporated these new assumptions, adjusted for the Sempra Energy companies’ actual mortality experience, in our calculations. We use a December 31 measurement date for all of our plans.
	Rabbi Trust
	In support of its Supplemental Executive Retirement, Cash Balance Restoration and Deferred Compensation Plans, Sempra Energy maintains dedicated assets, including a Rabbi Trust and investments in life insurance contracts, which totaled $512 million and $506 million at December 31, 2014 and 2013, respectively.
	Pension and Other Postretirement Benefit Plans
	Benefit Plan Amendments Affecting 2014
	During 2014, executive participants in a company nonqualified plan became eligible in this same plan for Supplemental Executive Retirement Plan benefits. Consistent with past practice, this was treated as a plan amendment and increased the recorded pension liability by $4 million at Sempra Energy Consolidated.
	Effective January 1, 2014, a new high deductible medical benefit was provided to all SDG&E and SoCalGas retirees under the age of 65, except the represented retirees at SoCalGas, participating in the companies’ PBOP plans. This benefit replaced a previous benefit provided by the SDG&E plans and was an added benefit in the SoCalGas plan. These changes resulted in an increase of other postretirement benefit obligations by a negligible amount at SDG&E and by $1 million at each of Sempra Energy Consolidated and SoCalGas.
	Benefit Plan Amendments Affecting 2013
	The plan amendments below were adopted in 2013, and are therefore reflected in the 2013 pension and other postretirement benefit obligations.
	Effective July 1, 2014, an enhanced pension benefit is provided to certain employees of SoCalGas who transfer from a represented to a nonrepresented position after June 30, 1998. This increased the pension benefit obligation by $27 million at each of Sempra Energy Consolidated and SoCalGas.
	Effective April 1, 2014, we provided a one-time, ad hoc cost of living adjustment of 13.2 percent for SoCalGas and PE retirees who retired prior to July 1, 1996 and their beneficiaries that are receiving qualified pension benefits in the form of an annuity. This election increased the pension benefit obligation by $40 million at Sempra Energy Consolidated and $39 million at SoCalGas.
	Effective January 1, 2013, the face value of the fully paid life insurance benefit for employees that participate in our Executive Retirement Life Insurance Program and retire after December 31, 2012 was increased from one times pay to one-and-a-half times pay. In addition, the tax gross-ups paid to the retiring employee based on the value of the final premium were eliminated. These changes resulted in a decrease of the other postretirement benefit obligation of $4 million at Sempra Energy Consolidated.
	Effective January 1, 2014, the benefits provided by one of the dental plans available to all employees that participate in the plans, except the represented employees at SoCalGas, were enhanced to increase the annual total maximum and lifetime orthodontic maximum covered costs. In addition, the costs of diagnostic and preventive services were excluded from the total covered annual maximum costs. These plan design changes increased the recorded liability for other postretirement benefits by $1 million at each of Sempra Energy Consolidated and SoCalGas.
	Special Termination Benefits Affecting 2014 and 2013
	At SDG&E in 2014, and at both SDG&E and SoCalGas in 2013, all nonrepresented employees age 62 with 5 years of service and all other nonrepresented employees age 55 with 10 years of service that retired under the Voluntary Retirement Enhancement Program (VREP) offered in those years received an additional postretirement health benefit in the form of a $50,000 Health Reimbursement Account (HRA). In accordance with U.S. GAAP, we elected to treat the benefit obligation attributable to the HRA as special termination benefits. This resulted in increases to the recorded liability for other postretirement benefits of approximately $5 million for each of Sempra Energy Consolidated and SDG&E in 2014, and $5 million for Sempra Energy Consolidated and $2 million for each of SDG&E and SoCalGas in 2013.
	Benefit Obligations and Assets
	The following three tables provide a reconciliation of the changes in the plans’ projected benefit obligations and the fair value of assets during 2014 and 2013, and a statement of the funded status at December 31, 2014 and 2013:

For Sempra Energy Consolidated, SDG&E and SoCalGas, the actuarial losses for pension plans in 2014 were primarily due to a decrease in the weighted average discount rates and updated mortality rates (discussed above), and to a lesser extent at SoCalGas, a change in the rate used to convert annuity benefits to lump sums. The actuarial losses were partially offset at Sempra Energy Consolidated and SoCalGas by the impact of updated census data for SoCalGas and partially offset at all companies by a decrease in the cash balance interest crediting rate.
The actuarial losses for other postretirement plans in 2014 were primarily due to a decrease in the weighted average discount rates and updated mortality rates for all companies, and to lesser extent, updated census data for SDG&E and SoCalGas. The actuarial losses were partially offset by a decrease in anticipated retiree and spousal participation rates for all companies.
The actuarial gains for pension plans in 2013 were primarily due to an increase in the weighted average discount rate and the rate used to convert monthly annuity-type benefits to a lump sum benefit payment.
The actuarial gains for other postretirement plans in 2013 resulted from several factors, including an increase in the discount rate, updated census data and actual claims costs at SoCalGas, updates in actual premiums and retiree contributions for 2013, expected decrease in 2014 claims costs based on 2014 renewal premium rates, and a decrease in the healthcare cost trending rate. The actuarial gains were partially offset by the impact of updated census data and actual claims costs at all companies except SoCalGas, changes in retirement and termination rates, and an expected increase in non-spouse dependents for all employees of SoCalGas not covered by the defined dollar benefit.
Net Assets and Liabilities
The assets and liabilities of the pension and other postretirement benefit plans are affected by changing market conditions as well as when actual plan experience is different than assumed. Such events result in investment gains and losses, which we defer and recognize in pension and other postretirement benefit costs over a period of years. Sempra Energy Consolidated (except for SDG&E) and SoCalGas use the asset smoothing method for their pension and other postretirement plans. This method develops an asset value that recognizes realized and unrealized investment gains and losses over a three-year period. This adjusted asset value, known as the market-related value of assets, is used in conjunction with an expected long-term rate of return to determine the expected return-on-assets component of net periodic cost. SDG&E does not use the asset smoothing method, but rather recognizes realized and unrealized investment gains and losses during the current year.
The 10-percent corridor accounting method is used at Sempra Energy Consolidated, SDG&E and SoCalGas. Under the corridor accounting method, if as of the beginning of a year unrecognized net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the market-related value of plan assets, the excess is amortized over the average remaining service period of active participants. The asset smoothing and 10-percent corridor accounting methods help mitigate volatility of net periodic costs from year to year.
We recognize the overfunded or underfunded status of defined benefit pension and other postretirement plans as assets or liabilities, respectively; unrecognized changes in these assets and/or liabilities are normally recorded in Accumulated Other Comprehensive Income (Loss) on the balance sheet. The California Utilities and Mobile Gas record regulatory assets and liabilities that offset the funded pension and other postretirement plans’ assets or liabilities, as these costs are expected to be recovered in future utility rates based on agreements with regulatory agencies. At Willmut Gas, pension contributions are recovered in rates on a prospective basis, but are not recorded as a regulatory asset pending recovery.
The California Utilities record annual pension and other postretirement net periodic benefit costs equal to the contributions to their plans as authorized by the CPUC. The annual contributions to the pension plans are limited to a minimum required funding amount as determined by the Internal Revenue Service. The annual contributions to the other postretirement plans are equal to the lesser of the maximum tax deductible amount or the net periodic cost calculated in accordance with U.S. GAAP for pension and other postretirement benefit plans. Mobile Gas records annual pension and other postretirement net periodic benefit costs based on an estimate of the net periodic cost at the beginning of the year calculated in accordance with U.S. GAAP for pension and other postretirement benefit plans, as authorized by the Alabama Public Service Commission. Any differences between booked net periodic benefit cost and amounts contributed to the pension and other postretirement plans for the California Utilities are disclosed as regulatory adjustments in accordance with U.S. GAAP for regulated entities.

The estimated net loss for the pension plans that will be amortized from Accumulated Other Comprehensive Income (Loss) into net periodic benefit cost in 2015 is $9 million for Sempra Energy Consolidated, $1 million for SDG&E and $1 million for SoCalGas. Negligible amounts of prior service credit for the pension plans will be similarly amortized in 2015.
Assumptions for Pension and Other Postretirement Benefit Plans
Benefit Obligation and Net Periodic Benefit Cost
Except for the Chilquinta Energía plans, we develop the discount rate assumptions based on the results of a third party modeling tool that develops the discount rate by matching each plan’s expected cash flows to interest rates and expected maturity values of individually selected bonds in a hypothetical portfolio. The model controls the level of accumulated surplus that may result from the selection of bonds based solely on their premium yields by limiting the number of years to look back for selection to 3 years for pre-30-year and 6 years for post-30-year benefit payments. Additionally, the model ensures that an adequate number of bonds are selected in the portfolio by limiting the amount of the plan’s benefit payments that can be met by a single bond to 7.5 percent.
We selected individual bonds from a universe of Bloomberg AA-rated bonds which:
have an outstanding issue of at least $50 million;
are non-callable (or callable with make-whole provisions);
exclude collateralized bonds; and
exclude the top and bottom 10 percent of yields to avoid relying on bonds which might be mispriced or misgraded.
This selection methodology also mitigates the impact of market volatility on the portfolio by excluding bonds with the following characteristics:
The issuer is on review for downgrade by a major rating agency if the downgrade would eliminate the issuer from the portfolio.
Recent events have caused significant price volatility to which rating agencies have not reacted.
Lack of liquidity is causing price quotes to vary significantly from broker to broker.
We believe that this bond selection approach provides the best estimate of discount rates to estimate settlement values for our plans’ benefit obligations as required by applicable U.S. GAAP.
We develop the discount rate assumptions for the plans at Chilquinta Energía based on 10-year Chilean government bond yields and the expected local long-term rate of inflation. This method for developing the discount rate is required when there is no deep market for high quality corporate bonds.
Long-term return on assets is based on the weighted-average of the plans’ investment allocation as of the measurement date and the expected returns for those asset types.
The significant assumptions affecting benefit obligation and net periodic benefit cost are as follows:

Health Care Cost Trend Rates
Assumed health care cost trend rates have a significant effect on the amounts that we report for the health care plan costs. Following are the health care cost trend rates applicable to our postretirement benefit plans

Plan Assets
Investment Allocation Strategy for Sempra Energy’s Pension Master Trust
Sempra Energy’s pension master trust holds the investments for the pension and other postretirement benefit plans. We maintain additional trusts as we discuss below for certain of the California Utilities’ other postretirement benefit plans. Other than through indexing strategies, the trusts do not invest in securities of Sempra Energy.
The current asset allocation objective for the pension master trust is to protect the funded status of the plans while generating sufficient returns to cover future benefit payments and accruals. We assess the portfolio performance by comparing actual returns with relevant benchmarks. Currently, the pension plans’ asset allocations are
38 percent domestic equity
26 percent international equity
18 percent long credit
5 percent global high yield credit
5 percent real assets
4 percent STRIPS
4 percent long government
The asset allocation of the plans is reviewed by our Plan Funding Committee and our Pension and Benefits Investment Committee (the Committees) on a regular basis. When evaluating strategic asset allocations, the Committees consider many variables, including:
long-term cost
variability and level of contributions
funded status
a range of expected outcomes over varying confidence levels
We maintain allocations at strategic levels with reasonable bands of variance. When asset class exposure reaches a minimum or maximum level, we generally rebalance the portfolio back to target allocations.
In accordance with the Sempra Energy pension investment guidelines, derivative financial instruments may be used by the pension master trust’s equity and fixed income portfolio investment managers to equitize cash, hedge certain exposures, and as substitutes for certain types of fixed income securities.
Rate of Return Assumption
The expected return on assets in our pension plans and other postretirement benefit plans is based on the weighted-average of the plans’ investment allocations to specific asset classes as of the measurement date. We arrive at a 7 percent expected return on assets by considering both the historical and forecasted long-term rates of return on those asset classes. We expect a return of between 7 percent and 9 percent on return-seeking assets and between 3 percent and 5 percent for risk-mitigating assets. Certain trusts that hold assets for the SDG&E and Mobile Gas other postretirement benefit plans are subject to taxation, which impacts the expected after-tax return on assets in these plans.
Concentration of Risk
Plan assets are fully diversified across global equity and bond markets, and other than what is indicated by the target asset allocations, contain no concentration of risk in any one economic, industry, maturity or geographic sector.
Investment Strategy for SDG&E’s and SoCalGas’ Other Postretirement Benefit Plans
SDG&E’s and SoCalGas’ other postretirement benefit plans are funded by cash contributions from SDG&E and SoCalGas and their current retirees. The assets of these plans are placed into the pension master trust and other Voluntary Employee Beneficiary Association (VEBA) trusts. The assets in the VEBA trusts are invested at an allocation similar to the pension master trust, with 70 percent invested in return-seeking and 30 percent invested in risk-mitigating assets. This allocation has been formulated to best suit the long-term nature of the obligations.
Fair Value of Pension and Other Postretirement Benefit Plan Assets
We classify the investments in Sempra Energy’s pension master trust and the trusts for the California Utilities’ other postretirement benefit plans into:
Level 1, for securities valued using quoted prices from active markets for identical assets;
Level 2, for securities not traded on an active market but for which observable market inputs are readily available; and
Level 3, for securities and investments valued based on significant unobservable inputs. Investments are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
The following are descriptions of the valuation methods and assumptions we use to estimate the fair values of investments held by pension and other postretirement benefit plan trusts.
Equity Securities — Equity securities are valued using quoted prices listed on nationally recognized securities exchanges.
Fixed Income Securities — Certain fixed income securities are valued at the closing price reported in the active market in which the security is traded. Other fixed income securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings. When quoted prices are not available for identical or similar securities, the security is valued under a discounted cash flows approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable, such as credit and liquidity risks. Certain high yield fixed-income securities are valued by applying a price adjustment to the bid side to calculate a mean and ask value. Adjustments can vary based on maturity, credit standing, and reported trade frequencies. The bid to ask spread is determined by the investment manager based on the review of the available market information.
Registered Investment Companies — Investments in mutual funds sponsored by a registered investment company are valued based on exchange listed prices for equity and certain fixed income securities or are valued under a discounted cash flows approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable, such as credit and liquidity risks for the remaining fixed income securities.
Common/Collective Trusts — Investments in common/collective trust funds are valued based on the redemption price of units owned, which is based on the current fair value of the funds’ underlying assets.
Private Equity Funds — Investments in private equity funds do not trade in active markets. Fair value is determined by the fund managers, based upon their review of the underlying investments as well as their utilization of discounted cash flows and other valuation models.
Venture Capital Funds — These funds consist of investments in private equities that are held by limited partnerships following various strategies, including venture capital and corporate finance. The partnerships generally have limited lives of 10 years, after which liquidating distributions will be received.  Fair value is determined by attributing a proportionate share of net assets to an ownership interest in partners’ capital.
Real Estate Funds — Investments in real estate funds are valued based on the net asset value per share. Net asset value is based on the fair value of the underlying investments.
Derivative Financial Instruments — Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies, and unrealized gain (loss) is recorded daily. Fixed income futures and options are marked to market daily. Equity index future contracts are valued at the last sales price quoted on the exchange on which they primarily trade.
The methods described are intended to produce a fair value calculation that is indicative of net realizable value or reflective of future fair values. However, while management believes the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
We provide more discussion of fair value measurements in Notes 1 and 10. The following tables set forth by level within the fair value hierarchy a summary of the investments in our pension and other postretirement benefit plan trusts measured at fair value on a recurring basis.
There were no transfers into or out of Level 1, Level 2 or Level 3 for Sempra Energy Consolidated, SDG&E or SoCalGas during the periods presented, nor any changes in the valuation techniques used in recurring fair value measurement.
The fair values of our pension plan assets by asset category are as follows:

PROFIT SHARING PLANS
Under Chilean law, Chilquinta Energía is required to pay all employees either (1) 30 percent of Chilquinta Energía’s taxable income after deducting a 10 percent return on equity, allocated in proportion to the annual salary of each employee or (2) 25 percent of each employee’s annual salary, with a maximum mandatory profit sharing of 4.75 months of Chile’s legal minimum salary. Chilquinta Energía has elected the second option but calculates the profit sharing amounts with actual employee salaries instead of the legal minimum salary, resulting in a higher cost. The amounts are paid out each pay period. Chilquinta Energía recorded annual profit sharing expense of $4 million for 2014, $4 million for 2013 and $6 million for 2012 related to this plan.
Under Peruvian law, Luz del Sur is required to pay their employees 5 percent of Luz del Sur’s taxable income, paid once a year and allocated as follows: 50 percent based on each employee’s annual hours worked and 50 percent based on each employee’s annual salary. Luz del Sur recorded annual profit sharing expense of $10 million for 2014, $9 million for 2013 and $10 million for 2012 related to this plan.
SAVINGS PLANS
Sempra Energy offers trusteed savings plans to all domestic employees and to employees in Mexico. Participation in the plans is immediate for salary deferrals for all employees except for the represented employees at SoCalGas, who are eligible upon completion of one year of service. Subject to plan provisions, domestic employees may contribute from one percent to 50 percent of their regular earnings, subject to annual IRS limits. In Mexico, employees may contribute up to 2 percent of the portion of their base salary that is less than 25 times the minimum wage and may contribute up to 5 percent of any portion of their base salary that is greater than 25 times the minimum wage. Sempra Energy makes matching contributions for domestic employees after one year of the employee’s completed service and immediately for employees in Mexico. Employer contribution amounts and methodology vary by plan for domestic employees, but generally the contributions are equal to 50 percent of the first 6 percent of eligible base salary contributed by employees and, if certain company goals are met, an additional amount related to incentive compensation payments. Employer contributions for employees in Mexico equal the contributions made by the employee.
Beginning September 1, 2012 for the Sempra Energy, SDG&E and Mobile Gas savings plans and October 1, 2012 for the SoCalGas savings plan, employer contributions are invested based upon each employee’s investment elections in effect at the time of contribution. Prior to that, employer contributions were initially invested in Sempra Energy common stock, but the employee could transfer the contribution to other investments. Contributions are invested in Sempra Energy common stock, mutual funds and/or institutional trusts. Prior to the termination of the ESOP discussed below, employer contributions for substantially all plans were partially funded by the ESOP.
Contributions to the savings plans were as follows:

The market value of Sempra Energy common stock held by the savings plans was $1.4 billion and $1.3 billion at December 31, 2014 and 2013, respectively.
Employee Stock Ownership Plan (ESOP)
Sempra Energy terminated the ESOP effective June 30, 2012, as all ESOP debt was paid and all shares were released from the ESOP Trust as of that date. Prior to the plan’s termination, all contributions to the ESOP Trust (Trust) were made by Sempra Energy; there were no contributions made by the participants. The Trust was used to fund part of the retirement savings plan described above. As Sempra Energy made contributions, the ESOP debt service was paid and shares were released in proportion to the total expected debt service. We charged compensation expense and credited equity for the market value of the released shares. Dividends on unallocated shares were used to pay debt service and were applied against the liability.
ESOP debt was paid down by a total of $10 million in 2012 when 153,625 shares of Sempra Energy common stock were released from the Trust in order to fund employer contributions to the Sempra Energy savings plan trust. Interest on the ESOP debt and dividends used for debt service were negligible in 2012.

Notes to Consolidated Financial Statements [Abstract]
Share-based Compensation	NOTE 8. SHARE-BASED COMPENSATION
	SEMPRA ENERGY EQUITY COMPENSATION PLANS
	Sempra Energy has share-based compensation plans intended to align employee and shareholder objectives related to the long-term growth of Sempra Energy. The plans permit a wide variety of share-based awards, including:
	non-qualified stock options
	incentive stock options
	restricted stock
	restricted stock units
	stock appreciation rights
	performance awards
	stock payments
	dividend equivalents
	Eligible California Utilities employees participate in Sempra Energy’s share-based compensation plans as a component of their compensation package.
	In May 2013, shareholders approved the Sempra Energy 2013 Long-Term Incentive Plan. Upon approval, the remaining authorized shares from the Sempra Energy 2008 Long Term Incentive Plan and the 2008 Long Term Incentive Plan for EnergySouth, Inc. Employees and Other Eligible Individuals were applied to the number of shares authorized in the 2013 Plan.
	At December 31, 2014, Sempra Energy had the following types of equity awards outstanding:
	Non-Qualified Stock Options: Options have an exercise price equal to the market price of the common stock at the date of grant, are service-based, become exercisable over a four-year period, and expire 10 years from the date of grant. Vesting and/or the ability to exercise may be accelerated upon a change in control, in accordance with severance pay agreements, in accordance with the terms of the grant, or upon eligibility for retirement. Options are subject to forfeiture or earlier expiration when an employee terminates employment.
	Performance-Based Restricted Stock Units: These restricted stock unit awards generally vest in Sempra Energy common stock at the end of four-year performance periods based on Sempra Energy’s total return to shareholders relative to that of market indices or based on earnings per common share (EPS) growth. For awards granted in 2013 or earlier, if Sempra Energy’s total return to shareholders exceeds target levels, up to an additional 50 percent of the number of granted restricted stock units may be issued. For awards granted in 2014, up to an additional 100 percent of the granted restricted stock units may be issued if total return to shareholders or EPS growth exceeds target levels. If Sempra Energy’s total return to shareholders or EPS growth is below the target levels, shares are subject to partial vesting on a pro rata basis. Vesting may be subject to earlier forfeiture upon termination of employment and accelerated vesting upon a change in control under the applicable long-term incentive plan, or in accordance with severance pay agreements. Dividend equivalents on shares subject to restricted stock units are reinvested to purchase additional shares that become subject to the same vesting conditions as the restricted stock units to which the dividends relate.
	Service-Based Restricted Stock Units: Restricted stock units may also be service-based; these generally vest at the end of four years of service. Vesting may be subject to earlier forfeiture upon termination of employment and accelerated vesting upon a change in control under the applicable long-term incentive plan, in accordance with severance pay agreements, or at the discretion of the Compensation Committee of Sempra Energy’s Board of Directors. Dividend equivalents on shares subject to restricted stock units are reinvested to purchase additional shares that become subject to the same vesting conditions as the restricted stock units to which the dividends relate.
	Other Restricted Stock Units: Restricted stock units were granted in 2014 in connection with the creation of the Cameron LNG Holdings joint venture. These awards vest to the extent that the Compensation Committee of Sempra Energy’s Board of Directors determines that the objectives of the joint venture are continuing to be achieved. These awards vest on the anniversary of the grant date over a period of either two or three years. Vesting may be subject to earlier forfeiture upon termination of employment and accelerated vesting upon a change in control under the applicable long-term incentive plan, or in accordance with severance pay agreements. Dividend equivalents on shares subject to restricted stock units are reinvested to purchase additional shares that become subject to the same vesting conditions as the restricted stock units to which the dividends relate.
	Restricted Stock: Restricted stock awards are solely service-based and are generally exercisable at the end of four years of service. Vesting is subject to earlier forfeiture upon termination of employment and accelerated vesting upon a change in control under the applicable long-term incentive plan, in accordance with severance pay agreements or upon eligibility for retirement. Holders of restricted stock have full voting rights. They also have full dividend rights; however, dividends paid on restricted stock held by officers are reinvested to purchase additional shares that become subject to the same vesting conditions as the restricted stock to which the dividends relate.
	In April 2013, the IEnova board of directors approved the IEnova 2013 Long-Term Incentive Plan. The purpose of this plan is to align the interests of employees and directors of IEnova with its shareholders. All awards issued from this plan and any related dividend equivalents will settle in cash based on the fair market value of the awards, based on IEnova’s common stock value, upon vesting. In 2014 and 2013, IEnova issued 468,339 and 1,014,899 restricted stock units from this plan, respectively, 962,122 of which remain outstanding at December 31, 2014.
	SHARE-BASED AWARDS AND COMPENSATION EXPENSE
	We measure and recognize compensation expense for all share-based payment awards made to our employees and directors based on estimated fair values on the date of grant. We recognize compensation costs net of an estimated forfeiture rate (based on historical experience) and recognize the compensation costs for non-qualified stock options and restricted stock and stock units on a straight-line basis over the requisite service period of the award, which is generally four years. However, in the year that an employee becomes eligible for retirement, the remaining expense related to the employee’s awards is recognized immediately. Substantially all awards outstanding are classified as equity instruments; therefore, we recognize additional paid in capital as we recognize the compensation expense associated with the awards.
	At December 31, 2014, 6,562,347 shares were authorized and available for future grants of share-based awards. Our practice is to satisfy share-based awards by issuing new shares rather than by open-market purchases.
	Total share-based compensation expense for all of Sempra Energy’s share-based awards was comprised as follows:
	SHARE-BASED COMPENSATION EXPENSE ― SEMPRA ENERGY CONSOLIDATED

	Sempra Energy Consolidated’s capitalized compensation cost was $5 million in 2014 and $4 million in each of 2013 and 2012.
	We classify the tax benefits resulting from tax deductions in excess of the tax benefit related to compensation cost recognized for stock option exercises as financing cash flows.
	Sempra Energy subsidiaries record an expense for the plans to the extent that subsidiary employees participate in the plans and/or the subsidiaries are allocated a portion of the Sempra Energy plans’ corporate staff costs. Expenses and capitalized compensation costs recorded by SDG&E and SoCalGas were as follows:

	Capitalized compensation cost		2		1		1
	SEMPRA ENERGY NON-QUALIFIED STOCK OPTIONS
	We use a Black-Scholes option-pricing model (Black-Scholes model) to estimate the fair value of each non-qualified stock option grant. The use of a valuation model requires us to make certain assumptions about selected model inputs. Expected volatility is calculated based on the historical volatility of Sempra Energy’s stock price. We base the average expected life for options on the contractual term of the option and expected employee exercise and post-termination behavior.
	The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of the grant. No new options were granted in 2014, 2013 or 2012.
	The following table shows a summary of non-qualified stock options at December 31, 2014 and activity for the year then ended:
	NON-QUALIFIED STOCK OPTIONS

	Exercisable at December 31, 2014		757,412	$	53.84		3.2	$	44
	The aggregate intrinsic value at December 31, 2014 is the total of the difference between Sempra Energy’s closing stock price and the exercise price for all in-the-money options. The aggregate intrinsic value for non-qualified stock options exercised in the last three years was
$33 million in 2014
$41 million in 2013
$45 million in 2012
The total fair value of shares vested in the last three years was
$1 million in 2014
$2 million in 2013
$4 million in 2012
We received cash from option exercises during 2014 totaling $37 million. There were no realized tax benefits for the share-based payment award deductions in 2014 over and above the $18 million income tax benefit shown above.
SEMPRA ENERGY RESTRICTED STOCK AWARDS AND UNITS
We use a Monte-Carlo simulation model to estimate the fair value of the restricted stock awards and units. Our determination of fair value is affected by the volatility of the stock price and the dividend yields for Sempra Energy and its peer group companies. The valuation also is affected by the risk-free rates of return, and a number of other variables. Below are key assumptions for 2014, 2013 and 2012 for Sempra Energy:
		2014		2013		2012
Risk-free rate of return		1.2	%	0.6	%	0.6	%
Annual dividend yield(1)		N/A		3.3		3.4

Notes to Consolidated Financial Statements [Abstract]
Derivative Financial Instruments	NOTE 9. DERIVATIVE FINANCIAL INSTRUMENTS
	We use derivative instruments primarily to manage exposures arising in the normal course of business. Our principal exposures are commodity market risk and benchmark interest rate risk. We may also manage foreign exchange rate exposures using derivatives. Our use of derivatives for these risks is integrated into the economic management of our anticipated revenues, anticipated expenses, assets and liabilities. Derivatives may be effective in mitigating these risks (1) that could lead to declines in anticipated revenues or increases in anticipated expenses, or (2) that our asset values may fall or our liabilities increase. Accordingly, our derivative activity summarized below generally represents an impact that is intended to offset associated revenues, expenses, assets or liabilities that are not presented below.
	We record all derivatives at fair value on the Consolidated Balance Sheets. We designate each derivative as (1) a cash flow hedge, (2) a fair value hedge, or (3) undesignated. Depending on the applicability of hedge accounting and, for the California Utilities and other operations subject to regulatory accounting, the requirement to pass impacts through to customers, the impact of derivative instruments may be offset in other comprehensive income (cash flow hedge), on the balance sheet (fair value hedges and regulatory offsets), or recognized in earnings. We classify cash flows from the settlements of derivative instruments as operating activities on the Consolidated Statements of Cash Flows.
	In certain cases, we apply the normal purchase or sale exception to derivative accounting and have other commodity contracts that are not derivatives. These contracts are not recorded at fair value and are therefore excluded from the disclosures below.
	HEDGE ACCOUNTING
	We may designate a derivative as a cash flow hedging instrument if it effectively converts anticipated revenues or expenses to a fixed dollar amount. We may utilize cash flow hedge accounting for derivative commodity instruments, foreign currency instruments and interest rate instruments. Designating cash flow hedges is dependent on the business context in which the instrument is being used, the effectiveness of the instrument in offsetting the risk that a given future revenue or expense item may vary, and other criteria.
	We may designate an interest rate derivative as a fair value hedging instrument if it effectively converts our own debt from a fixed interest rate to a variable rate. The combination of the derivative and debt instrument results in fixing that portion of the fair value of the debt that is related to benchmark interest rates. Designating fair value hedges is dependent on the instrument being used, the effectiveness of the instrument in offsetting changes in the fair value of our debt instruments, and other criteria.
	ENERGY DERIVATIVES
	Our market risk is primarily related to natural gas and electricity price volatility and the specific physical locations where we transact. We use energy derivatives to manage these risks. The use of energy derivatives in our various businesses depends on the particular energy market, and the operating and regulatory environments applicable to the business.
	The California Utilities use natural gas energy derivatives, for the benefit of customers, with the objective of managing price risk and basis risks, and lowering natural gas costs. These derivatives include fixed price natural gas positions, options, and basis risk instruments, which are either exchange-traded or over-the-counter financial instruments. This activity is governed by risk management and transacting activity plans that have been filed with and approved by the CPUC. Natural gas derivative activities are recorded as commodity costs that are offset by regulatory account balances and are recovered in rates. Net commodity cost impacts on the Consolidated Statements of Operations are reflected in Cost of Electric Fuel and Purchased Power or in Cost of Natural Gas.
	SDG&E is allocated and may purchase congestion revenue rights (CRRs), which serve to reduce the regional electricity price volatility risk that may result from local transmission capacity constraints. Unrealized gains and losses do not impact earnings, as they are offset by regulatory account balances. Realized gains and losses associated with CRRs are recorded in Cost of Electric Fuel and Purchased Power, which is recoverable in rates, on the Consolidated Statements of Operations.
	Sempra Mexico and Sempra Natural Gas may use natural gas and electricity derivatives, as appropriate, to optimize the earnings of their assets which support the following businesses: LNG, natural gas transportation, power generation, and Sempra Natural Gas’ storage. Gains and losses associated with undesignated derivatives are recognized in Energy-Related Businesses Revenues or in Cost of Natural Gas, Electric Fuel and Purchased Power on the Consolidated Statements of Operations. Certain of these derivatives may also be designated as cash flow hedges. Sempra Mexico also uses natural gas energy derivatives with the objective of managing price risk and lowering natural gas prices at its Mexican distribution operations. These derivatives, which are recorded as commodity costs that are offset by regulatory account balances and recovered in rates, are recognized in Cost of Natural Gas on the Consolidated Statements of Operations.
	From time to time, our various businesses, including the California Utilities, may use other energy derivatives to hedge exposures such as the price of vehicle fuel.
	We summarize net energy derivative volumes at December 31, 2014 and 2013 as follows:
	NET ENERGY DERIVATIVE VOLUMES
				December 31,
	Segment and Commodity			2014	2013
	California Utilities:
	SDG&E:
		Natural gas		55 million MMBtu	43 million MMBtu	-1
		Congestion revenue rights		27 million MWh	33 million MWh	-2
	SoCalGas - natural gas			1 million MMBtu	2 million MMBtu
	Energy-Related Businesses:
	Sempra Natural Gas:
	Electric power			―	1 million MWh
	Natural gas			29 million MMBtu	15 million MMBtu
	-1	Million British thermal units
	-2	Megawatt hours
	In addition to the amounts noted above, we frequently use commodity derivatives to manage risks associated with the physical locations of our assets and other contractual obligations, such as natural gas purchases and sales.
	INTEREST RATE DERIVATIVES
	We are exposed to interest rates primarily as a result of our current and expected use of financing. We periodically enter into interest rate derivative agreements intended to moderate our exposure to interest rates and to lower our overall costs of borrowing. We utilize interest rate swaps typically designated as fair value hedges, as a means to achieve our targeted level of variable rate debt as a percent of total debt. In addition, we may utilize interest rate swaps, typically designated as cash flow hedges, to lock in interest rates on outstanding debt or in anticipation of future financings.
	Interest rate derivatives are utilized by the California Utilities as well as by other Sempra Energy subsidiaries. Although the California Utilities generally recover borrowing costs in rates over time, the use of interest rate derivatives is subject to certain regulatory constraints, and the impact of interest rate derivatives may not be recovered from customers as timely as described above with regard to natural gas derivatives. Interest rate derivatives are generally accounted for as hedges at the California Utilities, as well as at the rest of Sempra Energy’s subsidiaries. Separately, Otay Mesa VIE has entered into interest rate swap agreements to moderate its exposure to interest rate changes. This activity was designated as a cash flow hedge as of April 1, 2011.
	At December 31, 2014 and 2013, the net notional amounts of our interest rate derivatives, excluding the cross-currency swaps discussed below, were:

		Cash flow hedge(1)		325	2019		335	2019
	-1	Includes Otay Mesa VIE. All of SDG&E’s interest rate derivatives relate to Otay Mesa VIE.
	FOREIGN CURRENCY DERIVATIVES
	We are exposed to exchange rate movements at our Mexican subsidiaries, which have U.S. dollar denominated cash balances, receivables and payables (monetary assets and liabilities) that give rise to Mexican currency exchange rate movements for Mexican income tax purposes. These subsidiaries also have deferred income tax assets and liabilities that are denominated in the Mexican peso, which must be translated into U.S. dollars for financial reporting purposes. From time to time, we may utilize short-term foreign currency derivatives at our subsidiaries and at the consolidated level as a means to manage the risk of exposure to significant fluctuations in our income tax expense from these impacts. We may also utilize cross-currency swaps to hedge exposure related to Mexican peso-denominated debt at our Mexican subsidiaries and joint ventures. On February 14, 2013, Sempra Mexico entered into cross-currency swap agreements, which were designated as cash flow hedges.
	In addition, Sempra South American Utilities may utilize foreign currency derivatives at its subsidiaries and joint ventures as a means to manage foreign currency rate risk. We discuss such swaps at Chilquinta Energía’s Eletrans joint venture investment in Note 4.
	FINANCIAL STATEMENT PRESENTATION

-2	There was $1 million, $1 million and $2 million of hedge ineffectiveness related to these cash flow hedges in 2014, 2013 and 2012, respectively.
-3	There was negligible hedge ineffectiveness related to these cash flow hedges at SDG&E and SoCalGas in 2014, 2013 and 2012.
For Sempra Energy Consolidated we expect that losses of $19 million, which are net of income tax benefit, that are currently recorded in AOCI (including $13 million in noncontrolling interests, of which $12 million is related to Otay Mesa VIE at SDG&E) related to cash flow hedges will be reclassified into earnings during the next twelve months as the hedged items affect earnings. Actual amounts ultimately reclassified into earnings depend on the interest rates in effect when derivative contracts that are currently outstanding mature.
SoCalGas expects that negligible losses, which are net of income tax benefit, that are currently recorded in AOCI related to cash flow hedges will be reclassified into earnings during the next twelve months as the hedged items affect earnings.
For all forecasted transactions, the maximum term over which we are hedging exposure to the variability of cash flows at December 31, 2014 is approximately 14 years and 4 years for Sempra Energy Consolidated and SDG&E, respectively. The maximum term of hedged interest rate variability related to debt at equity method investees is 21 years.

CONTINGENT FEATURES
For Sempra Energy Consolidated and SDG&E, certain of our derivative instruments contain credit limits which vary depending upon our credit ratings. Generally, these provisions, if applicable, may reduce our credit limit if a specified credit rating agency reduces our ratings. In certain cases, if our credit ratings were to fall below investment grade, the counterparty to these derivative liability instruments could request immediate payment or demand immediate and ongoing full collateralization.
For Sempra Energy Consolidated, the total fair value of this group of derivative instruments in a net liability position at December 31, 2014 and 2013 is $9 million and $3 million, respectively. At December 31, 2014, if the credit ratings of Sempra Energy were reduced below investment grade, $9 million of additional assets could be required to be posted as collateral for these derivative contracts.
For SDG&E, the total fair value of this group of derivative instruments in a net liability position at December 31, 2014 and 2013 is $2 million and $3 million, respectively. At December 31, 2014, if the credit ratings of SDG&E were reduced below investment grade, $2 million of additional assets could be required to be posted as collateral for these derivative contracts.
For Sempra Energy, SDG&E and SoCalGas, some of our derivative contracts contain a provision that would permit the counterparty, in certain circumstances, to request adequate assurance of our performance under the contracts. Such additional assurance, if needed, is not material and is not included in the amounts above.

FAIR_VALUE_MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended
	Dec. 31, 2014
Notes to Consolidated Financial Statements [Abstract]
Fair Value Measurements	NOTE 10. FAIR VALUE MEASUREMENTS
	Recurring Fair Value Measures
	The three tables below, by level within the fair value hierarchy, set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2014 and 2013. We classify financial assets and liabilities in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities, and their placement within the fair value hierarchy levels.
	The fair value of commodity derivative assets and liabilities is presented in accordance with our netting policy, as we discuss in Note 9 under “Financial Statement Presentation.”
	The determination of fair values, shown in the tables below, incorporates various factors, including but not limited to, the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits, letters of credit and priority interests).
	Our financial assets and liabilities that were accounted for at fair value on a recurring basis at December 31, 2014 and 2013 in the tables below include the following:
	Nuclear decommissioning trusts reflect the assets of SDG&E’s nuclear decommissioning trusts, excluding cash balances. A third party trustee values the trust assets using prices from a pricing service based on a market approach. We validate these prices by comparison to prices from other independent data sources. Equity and certain debt securities are valued using quoted prices listed on nationally recognized securities exchanges or based on closing prices reported in the active market in which the identical security is traded (Level 1). Other debt securities are valued based on yields that are currently available for comparable securities of issuers with similar credit ratings (Level 2).
	We enter into commodity contracts and interest rate derivatives primarily as a means to manage price exposures. We may also manage foreign exchange rate exposures using derivatives. We primarily use a market approach with market participant assumptions to value these derivatives. Market participant assumptions include those about risk, and the risk inherent in the inputs to the valuation techniques. These inputs can be readily observable, market corroborated, or generally unobservable. We have exchange-traded derivatives that are valued based on quoted prices in active markets for the identical instruments (Level 1). We also may have other commodity derivatives that are valued using industry standard models that consider quoted forward prices for commodities, time value, current market and contractual prices for the underlying instruments, volatility factors, and other relevant economic measures (Level 2). All Level 3 recurring items are related to CRRs at SDG&E, as we discuss below under “Level 3 Information.” We record commodity derivative contracts that are subject to rate recovery as commodity costs that are offset by regulatory account balances and are recovered in rates.
	Investments include marketable securities that we value using a market approach based on closing prices reported in the active market in which the identical security is traded (Level 1).
	There were no transfers into or out of Level 1, Level 2 or Level 3 for Sempra Energy Consolidated, SDG&E or SoCalGas during the periods presented, nor any changes in valuation techniques used in recurring fair value measurements.

Level 3 Information
The following table sets forth reconciliations of changes in the fair value of congestion revenue rights (CRRs) classified as Level 3 in the fair value hierarchy for Sempra Energy Consolidated and SDG&E:

Change in unrealized gains or losses relating to
instruments still held at December 31	$	8	$	11	$	17
SDG&E’s Energy and Fuel Procurement department, in conjunction with SDG&E’s finance group, is responsible for determining the appropriate fair value methodologies used to value and classify CRRs on an ongoing basis. Inputs used to determine the fair value of CRRs are reviewed and compared with market conditions to determine reasonableness. SDG&E expects all costs related to CRRs to be recoverable through customer rates. As such, there is no impact to earnings from changes in the fair value of these instruments.
CRRs are recorded at fair value based almost entirely on the most current auction prices published by the California ISO, an objective source. The impact associated with discounting is negligible. Because auction prices are a less observable input, these instruments are classified as Level 3. At December 31, 2014, the auction prices ranged from $(16) per MWh to $8 per MWh at a given location, and the fair value of these instruments is derived from auction price differences between two locations. At December 31, 2013, the auction prices ranged from $(6) per MWh to $12 per MWh. Positive values between two locations represent expected future reductions in congestion costs, whereas negative values between two locations represent expected future charges. Valuation of our CRRs is sensitive to a change in auction price. If auction prices at one location increase (decrease) relative to another location, this could result in a higher (lower) fair value measurement. We summarize CRR volumes in Note 9. Realized gains and losses associated with CRRs are recorded in Cost of Electric Fuel and Purchased Power, which is recoverable in rates, on the Consolidated Statements of Operations. Unrealized gains and losses are recorded as regulatory assets and liabilities and therefore also do not affect earnings.
Derivative Positions Net of Cash Collateral
Each Consolidated Balance Sheet reflects the offsetting of net derivative positions with fair value amounts for cash collateral with the same counterparty when management believes a legal right of offset exists.

Non-Recurring Fair Value Measures – Sempra Energy Consolidated
Energía Sierra Juárez
In July 2014, Sempra Mexico completed the sale of a 50-percent interest in the 155-MW first phase of its Energía Sierra Juárez wind project to a wholly owned subsidiary of InterGen N.V. for cash proceeds of $24 million, net of $2 million cash sold, as discussed in Note 3. Sempra Mexico recognized a pretax gain on the sale of $19 million ($14 million after-tax). Upon deconsolidation, our equity method investment in Energía Sierra Juárez was measured at fair value, which resulted in a $7 million after-tax gain attributable to a remeasurement of the retained investment to fair value. The fair value measurement was based on the cash sales price of $26 million paid by InterGen N.V., a nonrelated party and market participant. Use of this market participant input as the indicator of fair value is a Level 2 measurement in the fair value hierarchy.
Rockies Express
We discuss non-recurring fair value measures and the associated accounting impact on our investment in Rockies Express in Note 4.
In 2012, we recorded a $400 million pretax impairment of our investment in Rockies Express. In the second quarter of 2012, the noncash impairment charge of $300 million ($179 million after-tax) primarily resulted from the continuing decline in basis differential associated with shale gas production zones coming on line, assumptions related to the re-contracting of the long-term transportation agreements, and the refinancing of the existing project level debt, discussed further below. The fair value measurement was significantly impacted by unobservable inputs (Level 3) as defined by the accounting guidance for fair value measurements, which we discuss in Note 1 under “Fair Value Measurements.” We considered a market participant’s view of the total value for Rockies Express, based on an estimation of the future cash distributions it would be able to generate, adjusted for our 25-percent ownership interest. To estimate future cash distributions, we considered factors impacting Rockies Express’ ability to pay future distributions including:
the extent to which future cash flows are hedged by capacity sales contracts and their duration (generally through 2019), as well as the creditworthiness of the various counterparties;
Rockies Express’ future financing needs, including the ability to secure borrowings at reasonable rates as well as potentially using operating cash to retire principal;
prospects for generating attractive revenues and cash flows beyond 2019, including natural gas’ future basis differentials (driven by the location and extent of future supply and demand) and alternative strategies potentially available to utilize the assets; and
discount rates commensurate with the risks inherent in the cash flows.
In the third quarter of 2012, KMI reached an agreement with Tallgrass, which closed in the fourth quarter of 2012, to sell its asset group as mandated by the FTC, which group included its interest in Rockies Express. Events in the third quarter of 2012 related to this agreement also provided us with additional market participant data. We therefore updated our analysis of the fair value of our investment in Rockies Express as of September 30, 2012 to reflect these additional inputs and recorded an additional impairment charge of $100 million ($60 million after-tax). This fair value measurement in the third quarter was based primarily on the Level 2 input. We believe this is useful and reliable information, but we considered that it may be impacted by the FTC’s requirement for KMI to sell its interest in Rockies Express. To reflect this uncertainty, our updated analysis included the less subjective Level 2 market participant input as the primary indicator of fair value, with less weight ascribed to value based on estimated discounted cash flows as discussed above and in the table below. The updates to the cash flow analysis used in determining fair value in the second quarter reflected discussions with Tallgrass as to the strategic direction they are planning to take with their equity partners for Rockies Express, as well as additional discussions with other market participants. Tallgrass became the operator of Rockies Express in November 2012.
We believe our analysis formed a reasonable estimate of the fair value of Rockies Express at the measurement date of September 30, 2012. This estimate included the material input described above, which was generally observable during the period most relevant to our analysis. Regarding the unobservable inputs, significant uncertainties exist with regard to REX’s ability to secure attractive revenues beyond 2019. Accordingly, our analysis suggested that the fair value of our investment in Rockies Express could be materially different from the value we estimated at that time. For example, if REX is able to sustain the level of revenues currently generated beyond 2019, the value of our investment in Rockies Express would be materially enhanced and the indicated value of our investment in Rockies Express could be significantly higher. Conversely, if REX is unable to sell its transport capacity at sufficient rates or in sufficient volumes beyond 2019, the fair value of our investment in Rockies Express could be materially lower than our carrying amount. Separately, future events involving Rockies Express equity could occur and may also provide additional information regarding the fair value of our investment in Rockies Express.
Sempra Natural Gas developed the models and scenarios used to measure the fair value of our investment in Rockies Express. This modeling used inputs from external sources as described above and in the table below, as well as internally available data, such as operating and maintenance budgets used for financial planning purposes. External experts that forecast the future price of natural gas at various physical locations were also engaged to help validate certain scenarios and modeling assumptions. The fair value measurements were reviewed in detail by Sempra Natural Gas’ financial management, as well as Sempra Energy’s financial management team.
The following table summarizes significant inputs impacting non-recurring fair value measures related to our investments in Energía Sierra Juárez and Rockies Express:

Shareholders' Equity And Earnings Per Share	NOTE 12. SEMPRA ENERGY – SHAREHOLDERS’ EQUITY AND EARNINGS PER SHARE
	The following table provides the per share computations for our earnings for years ended December 31. Basic EPS is calculated by dividing earnings attributable to common stock by the weighted-average number of common shares outstanding for the year. Diluted EPS includes the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

	Dividends declared per share of common stock	$	2.64	$	2.52	$	2.4
	The dilution from common stock options is based on the treasury stock method. Under this method, proceeds based on the exercise price plus unearned compensation and windfall tax benefits recognized, minus tax shortfalls recognized, are assumed to be used to repurchase shares on the open market at the average market price for the period. The windfall tax benefits are tax deductions we would receive upon the assumed exercise of stock options in excess of the deferred income taxes we recorded related to the compensation expense on the stock options. Tax shortfalls occur when the assumed tax deductions are less than recorded deferred income taxes. The calculation of dilutive common stock equivalents excludes options for which the exercise price on common stock was greater than the average market price during the period (out-of-the-money options). We had no such antidilutive stock options outstanding during 2014 or 2013, and 40,000 such options outstanding during 2012.
	During 2014, 2013 and 2012, we had no stock options outstanding that were antidilutive because of the unearned compensation and windfall tax benefits recognized included in the assumed proceeds under the treasury stock method.
	The dilution from unvested restricted stock awards (RSAs) and restricted stock units (RSUs) is also based on the treasury stock method. Proceeds equal to the unearned compensation and windfall tax benefits recognized, minus tax shortfalls recognized, related to the awards and units are assumed to be used to repurchase shares on the open market at the average market price for the period. The windfall tax benefits recognized or tax shortfalls recognized are the difference between tax deductions we would receive upon the assumed vesting of RSAs or RSUs and the deferred income taxes we recorded related to the compensation expense on such awards and units. There were no antidilutive RSAs and 4,087 antidilutive RSUs from the application of unearned compensation in the treasury stock method in 2014. There were no such antidilutive RSAs or RSUs in 2013. There were 1,934 such antidilutive RSAs and 7,673 such antidilutive RSUs in 2012.
	Each performance-based RSU represents the right to receive up to 1.5 shares (2.0 shares for awards granted in 2014) of Sempra Energy common stock based on total shareholder return or EPS growth. RSU awards vest based on Sempra Energy’s four-year cumulative total shareholder return compared to the Standard & Poor’s (S&P) 500 Utilities Index, as follows:
	Four-year cumulative total shareholder return ranking versus S&P 500 Utilities Index(1)		Number of Sempra Energy common shares received for each performance-based restricted stock unit(2)(3)
	90th percentile or above (2014 awards only)		2
	75th percentile (maximum for awards prior to 2014)		1.5
	50th percentile		1
	35th percentile or below		―
	-1	If Sempra Energy ranks at or above the 50th percentile compared to the S&P 500 Index, participants will receive a minimum of 1.0 share for each RSU.
	-2	Participants also receive additional shares for dividend equivalents on shares subject to RSUs, which are deemed reinvested to purchase additional units that become subject to the same vesting conditions as the RSUs to which the dividends relate.
	-3	If performance falls between the tiers shown above, we calculate the payout using linear interpolation.
	Beginning in January 2014, we issued performance-based RSUs representing the right to receive up to 2.0 shares of Sempra Energy common stock based on Sempra Energy’s four-year EPS compound annual growth rate beginning January 1, 2014 and ending on December 31, 2017. These RSU awards vest as follows:
	Four-year earnings per share compound annual growth rate		Number of Sempra Energy common shares received for each performance-based restricted stock unit(1)(2)
	8.0% or above		2
	6.70%		1.5
	4.40%		1
	3.3% or below		―
	-1	Participants also receive additional shares for dividend equivalents on shares subject to RSUs, which are reinvested to purchase additional units that become subject to the same vesting conditions as the RSUs to which the dividends relate.
	-2	If performance falls between the tiers shown above, we calculate the payout using linear interpolation.
	Our RSAs, which are solely service-based, and those RSUs that are service-based or issued in connection with the creation of the Cameron LNG Holdings joint venture represent the right to receive up to 1.0 share over the course or at the end of the service period and have the same dividend equivalent rights as performance-based RSUs. We include RSAs and these RSUs in potential dilutive shares at 100 percent, subject to the application of the treasury stock method. We include our performance-based RSUs in potential dilutive shares at zero to up to 200 percent to the extent that they currently meet the performance requirements for vesting, subject to the application of the treasury stock method. Due to market fluctuations of both Sempra Energy stock and the comparative indices, dilutive performance-based RSU shares may vary widely from period-to-period. If it were assumed that performance goals for all RSUs were met at maximum levels and if the treasury stock method were not applied to any of our RSAs or RSUs, the incremental potential dilutive shares would be 949,351; 641,751 and 1,134,456 for the years ended December 31, 2014, 2013 and 2012, respectively.
	We are authorized to issue 750,000,000 shares of no-par-value common stock. In addition, we are authorized to issue 50,000,000 shares of preferred stock having rights, preferences and privileges that would be established by the Sempra Energy board of directors at the time of issuance.

Notes to Consolidated Financial Statements [Abstract]
Nuclear Plant	NOTE 13. SAN ONOFRE NUCLEAR GENERATING STATION (SONGS)
	SDG&E has a 20-percent ownership interest in SONGS, a nuclear generating facility near San Clemente, California, which ceased operations in June 2013. On June 6, 2013, Southern California Edison Company (Edison), the majority owner and operator of SONGS, notified SDG&E that it had reached a decision to permanently retire SONGS and seek approval from the Nuclear Regulatory Commission (NRC) to start the decommissioning activities for the entire facility. SONGS is subject to the jurisdiction of the NRC and the CPUC.
	SDG&E, and each of the other owners, holds its undivided interest as a tenant in common in the property. Each owner is responsible for financing its share of expenses and capital expenditures. SDG&E’s share of operating expenses is included in Sempra Energy’s and SDG&E’s Consolidated Statements of Operations.
	SONGS Outage and Retirement
	Background
	As part of the Steam Generator Replacement Project (SGRP), the steam generators were replaced in SONGS Units 2 and 3, and the Units returned to service in 2010 and 2011, respectively. Both Units were shut down in early 2012 after a water leak occurred in the Unit 3 steam generator. Edison concluded that the leak was due to unexpected wear from tube-to-tube contact. At the time the leak was identified, Edison also inspected and tested Unit 2 and subsequently found unexpected tube wear in Unit 2’s steam generator. In March 2012, in response to the shutdown of SONGS, the NRC issued a Confirmatory Action Letter (CAL) which, among other things, outlined the requirements for Edison to meet before the NRC would approve a restart of either of the Units.
	In October 2012, Edison submitted a restart plan to the NRC proposing to operate Unit 2 at a reduced power level for a period of five months, at which time the Unit would be brought down for further inspection. Edison did not file a restart plan for Unit 3, pending further inspection and analysis of what repairs or modifications would be required to return the Unit to service in a safe manner. The NRC was reviewing the restart plan for Unit 2 proposed by Edison when in May 2013, the Atomic Safety and Licensing Board (ASLB), an adjudicatory arm of the NRC, concluded that the CAL process constituted a de facto license amendment proceeding that was subject to a public hearing. This conclusion by the ASLB resulted in further uncertainty regarding when a final decision might be made on restarting Unit 2.
	The replacement steam generators were designed and provided by Mitsubishi Heavy Industries, Ltd., Mitsubishi Nuclear Energy Systems, Inc., and Mitsubishi Heavy Industries America, Inc. (collectively MHI). In July 2013, SDG&E filed a lawsuit against MHI seeking to recover damages SDG&E has incurred and will incur related to the design defects in the steam generators. In October 2013, Edison instituted arbitration proceedings against MHI seeking damages as well. We discuss these proceedings in Note 15.
	Settlement Agreement to Resolve the CPUC’s Order Instituting Investigation (OII) into the SONGS Outage (SONGS OII)
	SONGS OII
	In November 2012, in response to the outage, the CPUC issued the SONGS OII, pursuant to California Public Utilities’ Code Section 455.5, which applies to cost recovery issues resulting from long-term outages of operating assets. The SONGS OII consolidated most SONGS outage-related issues into a single proceeding. The SONGS OII, among other things, designated all revenues associated with the investment in, and operation of, SONGS since January 1, 2012 as subject to refund to customers, pending the outcome of all phases of the proceeding. The SONGS OII proceeding was intended to determine the ultimate recovery of the investment in SONGS and the costs incurred since the commencement of this outage, including purchased replacement power costs, which are typically recovered through the Energy Resource Recovery Account (ERRA).
	Entry Into Settlement Agreement
	Pursuant to CPUC rules concerning settlements, SDG&E, Edison, The Utility Reform Network (TURN), and the CPUC Office of Ratepayer Advocates (ORA) held a settlement conference in March 2014 to discuss the terms to resolve the SONGS OII, and in April 2014, SDG&E, along with Edison, TURN, ORA and two other intervenors who joined the Settlement Agreement to the SONGS OII proceeding (collectively, the Settling Parties), filed a Settlement Agreement with the CPUC. On September 5, 2014, the CPUC issued a ruling proposing specific changes that included, as they relate to SDG&E, greater ratepayer benefit from third party cost recoveries and funding of a research program to reduce greenhouse gas emissions at a shareholder cost of $1 million per year for 5 years.
	On September 23, 2014, the Settling Parties executed an Amended and Restated Settlement Agreement (Amended Settlement Agreement), which amended the Settlement Agreement to adopt all of the modifications and clarifications requested in the CPUC ruling. On October 9, 2014, the CPUC issued a proposed decision approving the Amended Settlement Agreement, which was adopted by the CPUC as a final decision on November 20, 2014.
	As approved by the CPUC, the Amended Settlement Agreement constitutes a complete and final resolution of the SONGS OII and related CPUC proceedings regarding the SGRP at SONGS and the related outage and subsequent shutdown of SONGS. The Amended Settlement Agreement does not affect on-going or future proceedings before the NRC, or litigation or arbitration related to potential future recoveries from third parties (except for the allocation to ratepayers of any recoveries as described below) or proceedings addressing decommissioning activities and costs.
	In November 2014, in accordance with the Amended Settlement Agreement, SDG&E filed an advice letter seeking authority from the CPUC, among other things, to implement the terms and establish the revenue requirement established by the Amended Settlement Agreement in rates starting January 1, 2015. In December 2014, the CPUC approved the advice letter and authorized SDG&E to update rates accordingly, subject to revision pending the results of a CPUC review of the changes to the revenue requirement proposed by SDG&E for consistency with the terms of the approved settlement decision. Upon conclusion of the CPUC’s review, SDG&E expects to receive a final disposition letter from the CPUC either confirming that SDG&E’s proposed rate changes were in compliance with the approved settlement decision or identifying changes that need to be made to the proposed rates and the resultant annual SONGS revenue requirement. Upon receipt of the final disposition letter, SDG&E will determine if final adjustment is necessary to increase or decrease the amount of the SONGS regulatory asset. SDG&E currently expects the CPUC to issue this final disposition letter in the first half of 2015.
	The following is a summary of the Amended Settlement Agreement as it relates to SDG&E.
	Disallowances, Refunds and Rate Recoveries
	Based on the final decision, SDG&E will
	remove from rate base, as of February 1, 2012, its investment in the SGRP and refund to its customers the amount collected for its investment in and any return on its investment in the SGRP since such date. As of February 1, 2012, SDG&E’s net book value in the SGRP was approximately $160 million;
	be authorized to recover in rates its remaining investment in SONGS, including base plant and construction work in progress (CWIP), generally over a ten-year period commencing February 1, 2012, together with a return on investment at a reduced rate equal to:
	SDG&E’s weighted average return on debt, plus
	50 percent of SDG&E’s weighted average return on preferred stock, as authorized in the CPUC’s Cost of Capital proceeding then in effect (collectively, SONGS rate of return or SONGS ROR).
	This results in a SONGS ROR of 2.75 percent for the period from February 1, 2012 through December 31, 2012 and 2.35 percent for the period from January 1, 2013 through December 31, 2014. The SONGS ROR for future periods will fluctuate based on SDG&E’s authorized weighted average returns on debt and preferred stock in effect for those future periods;
	be authorized to recover in rates its recorded 2012 and 2013 operations and maintenance expenses; in addition, SDG&E will be authorized to recover in rates the recorded costs for the 2012 refueling outage of Unit 2, subject to customary prudency review;
	be required to file an application in 2015 to recover in rates its 2014 recorded operation and maintenance expenses and non-operating operations and maintenance expenses;
	be authorized to recover in rates its remaining investment in materials and supplies over a ten-year period commencing February 1, 2012, together with a return on investment at the SONGS ROR;
	be authorized to recover in rates its remaining investment in nuclear fuel inventory and any costs incurred, or to be incurred, associated with nuclear fuel supply contracts over a ten-year period, together with a return equal to SDG&E’s commercial paper borrowing rate;
	be authorized to recover in rates through its fuel and purchased power balancing account (ERRA), subject to the normal CPUC compliance reviews, all costs incurred to purchase power in the market to replace the power that would have been generated at SONGS if not for the outage and shutdown of SONGS, and to recover by December 31, 2015 any SONGS-related ERRA undercollections. SDG&E’s replacement power purchase costs through June 6, 2013 (the date of SONGS’ retirement) were approximately $165 million, using the methodology followed in the SONGS OII; and
	have a five-year funding commitment of $1 million per year to the University of California (UC) Energy Institute (or other existing UC entity engaged in energy technology development) to create a Research Development and Demonstration program, whose goal would be to deploy new technologies, methodologies, and /or design modifications to reduce greenhouse gas (GHG) emissions, particularly at current and future generating plants in California. This term was a modification requested by the CPUC.
	Potential Third Party Recoveries
	The Amended Settlement Agreement also addresses how potential recoveries from third parties will be allocated between ratepayers and SDG&E, as we describe below.
	As we discuss in more detail in Note 15, SDG&E and the other owners of SONGS carry accidental property damage and accidental outage insurance issued by Nuclear Electric Insurance Limited (NEIL), a mutual insurance company. Edison, on behalf of itself and the other minority owners in SONGS (including SDG&E), has placed NEIL on notice of claims under both policies. Under the Amended Settlement Agreement, recoveries from NEIL, if any, will first be applied to reimburse costs incurred in pursuing such recoveries, including litigation costs. To the extent SDG&E’s share of recoveries from NEIL attributable to the NEIL accidental outage policy exceeds such costs, recoveries will be allocated 95 percent to ratepayers and 5 percent to SDG&E. To the extent SDG&E’s share of recoveries from other NEIL policies (such as the accidental property damage policy) exceeds such costs, recoveries will be allocated 82.5 percent to ratepayers and 17.5 percent to SDG&E.
	As we discuss in more detail in Note 15, SDG&E has filed a lawsuit against MHI, which designed and provided the steam generators that failed. This proceeding was stayed in favor of an arbitration proceeding instituted by Edison. Under the Amended Settlement Agreement, recoveries from MHI, if any, will first be applied to reimburse costs incurred in pursuing such recoveries, including litigation costs. To the extent SDG&E’s share of recoveries from MHI exceeds such costs, they will be allocated 50 percent to SDG&E and 50 percent to ratepayers.
	The Amended Settlement Agreement provides that the resolution of the claims with NEIL and the dispute with MHI do not require CPUC approval, but requires that Edison and SDG&E:
	use their best efforts to inform the CPUC of any settlements or resolutions of the issues to the extent possible without compromising any aspect of such settlements or resolutions, and
	allow the CPUC to review documentation of final resolution of third-party litigation and litigation costs to ensure that the ratepayer refund calculations are accurately calculated and that the litigation costs are not exorbitant in relation to the recovery obtained.
	There is no assurance that there will be any recoveries from NEIL or MHI or that if there are recoveries, that they will exceed the costs incurred to pursue them. Were there to be recoveries, SDG&E cannot provide any assurance as to when they would be received or the amount of any such recoveries. SDG&E currently expects that NEIL will make a coverage determination regarding the accidental outage policy by the end of 2015.
	The Amended Settlement Agreement also provides SDG&E with an incentive in the event proceeds are secured from the sale of materials and supplies and/or nuclear fuel, as well as in the event that nuclear fuel investments are reduced by contract cancellations. This incentive allows SDG&E to retain 5 percent of its proportionate share of any sales proceeds and to recover 5 percent of its proportionate share of the excess of cancelled contract obligations over cancellation costs. The balance of the sale proceeds and cancellation benefits would be credited to ratepayers.
	Accounting and Financial Impacts
	In the second quarter of 2013, SDG&E reported a pretax loss from plant closure of $200 million ($119 million after-tax) as a result of its initial assessment of the financial impact of the outcome of the SONGS OII proceeding. In the first quarter of 2014, as a result of entering into the Settlement Agreement, SDG&E recorded a $13 million reduction to the pretax loss from plant closure, but a $9 million increase in the after-tax loss from plant closure. The after-tax loss included a $17 million charge to reduce certain tax regulatory assets that may no longer be recoverable in rates pursuant to the Settlement Agreement. In the third quarter of 2014, SDG&E recorded a charge for the impact of the modifications and clarifications in the Amended Settlement Agreement on the regulatory asset, which charge was not material. In the fourth quarter of 2014, in conjunction with filing the advice letter regarding revenue requirement and determining the timing of refunds to ratepayers, SDG&E recorded a charge to Plant Closure Loss of $19 million pretax ($12 million after-tax). The total Plant Closure Loss in 2014 was $6 million pretax ($21 million after-tax). A regulatory asset for the expected recovery of SONGS costs, consistent with the Amended Settlement Agreement, is recorded on the Consolidated Balance Sheets of Sempra Energy and SDG&E in Other Regulatory Assets (long-term). The amount of this regulatory asset is $308 million at December 31, 2014.
	SDG&E does not expect that implementation of the Amended Settlement Agreement will have a material adverse impact on its future results of operations or financial condition.
	NRC Proceedings
	In December 2013, Edison received a final NRC Inspection Report that identified a violation for the failure to verify the adequacy of the thermal-hydraulic and flow-induced vibration design of the Unit 3 replacement steam generator. In January 2014, Edison provided a response to the NRC Inspection Report stating that MHI, as contracted by Edison to prepare the SONGS replacement steam generator design, was the party responsible for validating the design of the steam generators.
	In addition, the NRC issued an Inspection Report to MHI containing a Notice of Nonconformance for its flawed computer modeling in the design of the replacement steam generators.
	Because SONGS has ceased operation, NRC inspection oversight of SONGS will now be continued through the NRC’s Decommissioning Power Reactor Inspection Program to verify that decommissioning activities are being conducted safely, that spent fuel is safely stored onsite or transferred to another licensed location, and that the site operations and licensee termination activities conform to applicable regulatory requirements, licensee commitments and management controls.
	Nuclear Decommissioning and Funding
	As a result of Edison’s decision to permanently retire SONGS Units 2 and 3, Edison has begun the decommissioning phase of the plant. The process of decommissioning a nuclear power plant is governed by the regulations of various governmental and other agencies, including but not limited to, those of the NRC, the U.S. Department of the Navy (the land owner) and the CPUC. The NRC regulations generally categorize the decommissioning activities into three phases: initial activities, major decommissioning and storage activities, and license termination. Initial activities include providing notice of permanent cessation of operations (provided by Edison to the NRC on June 12, 2013) and notice of permanent removal of fuel from the reactor vessels (provided by Edison on June 28 and July 22, 2013 for Units 3 and 2, respectively). Within two years after the cessation of operations, the licensee (Edison) must submit a post-shutdown decommissioning activities report (PSDAR), an irradiated fuel management plan (IFMP) and a site-specific decommissioning cost estimate (DCE). Edison submitted each of the PSDAR, the IFMP and the DCE to the NRC in September 2014.
	In accordance with state and federal requirements and regulations, SDG&E has assets held in trusts, referred to as the Nuclear Decommissioning Trusts (NDT), to fund decommissioning costs for SONGS Units 1, 2 and 3. Decommissioning of Unit 1, removed from service in 1992, is largely complete. The remaining work will be done when Units 2 and 3 are decommissioned. At December 31, 2014, the fair value of SDG&E’s NDT assets was $1.1 billion. Except for the use of funds for the planning of decommissioning activities or NDT administrative costs, CPUC approval is required for SDG&E to access the NDT assets to fund SONGS decommissioning costs for Units 2 and 3. In February 2014, SDG&E filed a request with the CPUC for such authorization for costs incurred in 2013. Until CPUC approval to access the NDT to pay for such costs is received, SDG&E will use working capital to pay for any SONGS Units 2 and 3 decommissioning costs incurred, and such expenditures will be reimbursed from the NDT upon that approval.
	SDG&E currently anticipates a decision regarding its ability to use the monies in the NDT by the end of 2015.
	In December 2012, SDG&E and Edison filed a joint application with the CPUC requesting continued rate recovery to fund the NDT to ensure that the NDT has sufficient funding to pay for the estimated cost of decommissioning SONGS. SDG&E is currently authorized to recover $8 million annually to fund additional investments in the NDT. In December 2014, the CPUC issued a decision authorizing SDG&E to continue to collect and contribute to the NDT $8 million annually.
	In December 2014, SDG&E and Edison filed a joint application with the CPUC submitting a detailed study of the costs to decommission SONGS Units 2 and 3. The cost study estimates the total decommissioning costs for Units 2 and 3 at $4.411 billion, of which SDG&E’s share is $899 million. The joint application requests that the CPUC determine the cost study to be reasonable and asks that SDG&E’s contributions to the NDT be set at zero ($0.00) beginning January 1, 2016, given the current expectation that the NDT will be sufficiently funded over time. The application also requests that the CPUC approve a standardized process for regularly reviewing the reasonableness of decommissioning activities and costs and authorizing disbursements from the NDT.
	On September 5, 2014, the NRC approved Edison’s February 2014 request (made on behalf of SONGS co-owners) for exemptions from various federal decommissioning requirements. These exemptions provide NRC approval for SONGS co-owners to use NDT funds for all types of decommissioning activity costs, including fuel management and site restoration costs. As noted above, however, CPUC approval to access the NDT to pay for such costs is still required for SDG&E and Edison to use NDT funds.
	Edison’s submission of the PSDAR and the DCE in September 2014 allows the SONGS co-owners to commence major decommissioning activities, and submission of the DCE provides the NRC authorization for the SONGS co-owners to access the majority of their decommissioning trust funds, both starting 90 days after the NRC receives the documents, unless the NRC staff raises objections. No objections were received during the 90-day period.
	Nuclear Decommissioning Trusts
	The amounts collected in rates for SONGS’ decommissioning are invested in externally managed trust funds. Amounts held by the trusts are invested in accordance with CPUC regulations. These trusts are shown on the Sempra Energy and SDG&E Consolidated Balance Sheets at fair value with the offsetting credits recorded in Regulatory Liabilities Arising from Removal Obligations.
	The following table shows the fair values and gross unrealized gains and losses for the securities held in the trust funds. We provide additional fair value disclosures for the trusts in Note 10.

Customer contribution amounts are determined by the CPUC using estimates of after-tax investment returns, decommissioning costs, and decommissioning cost escalation rates. Changes in investment returns and decommissioning costs may result in a change in future customer contributions.
Asset Retirement Obligation and Spent Nuclear Fuel
SDG&E’s asset retirement obligation related to decommissioning costs for the SONGS units was $713 million at December 31, 2014. That amount includes the cost to decommission Units 2 and 3, and the remaining cost to complete the decommissioning of Unit 1, which is substantially complete. The asset retirement obligation at December 31, 2014 is based on an updated cost study prepared in 2014 that reflects the acceleration of the start of decommissioning Units 2 and 3 as a result of the early closure of the plant. SDG&E’s share of decommissioning costs in 2014 dollars is approximately $937 million.
Unit 1 was permanently shut down in 1992, and physical decommissioning began in January 2000. Most structures, foundations and large components have been dismantled, removed and disposed of. Spent nuclear fuel has been removed from the Unit 1 Spent Fuel Pool and stored on-site in an independent spent fuel storage installation (ISFSI) licensed by the NRC. The decommissioning of Unit 1 remaining structures (subsurface and intake/discharge) will take place as Units 2 and 3 are decommissioned. The ISFSI will be decommissioned after a permanent storage facility becomes available and the DOE removes the spent fuel from the site. The Unit 1 reactor vessel is expected to remain on site until Units 2 and 3 are fully decommissioned. Until then, SONGS owners are responsible for interim storage of spent nuclear fuel at SONGS until the DOE accepts it for final disposal. Spent nuclear fuel for Units 2 and 3 has been stored in the SONGS spent fuel pools for each reactor and in the ISFSI.
We provide additional information about SONGS in Note 15.

CALIFORNIA UTILITIES' REGULATORY MATTERS	12 Months Ended
	Dec. 31, 2014
Notes to Consolidated Financial Statements [Abstract]
Sempra Utilities' Regulatory Matters	NOTE 14. CALIFORNIA UTILITIES’ REGULATORY MATTERS
	JOINT MATTERS
	CPUC General Rate Case (GRC)
	The CPUC uses a general rate case proceeding to prospectively set rates sufficient to allow the California Utilities to recover their reasonable cost of operations and maintenance and to provide the opportunity to realize their authorized rates of return on their investment.
	The California Utilities filed their 2016 General Rate Case (2016 GRC) applications in November 2014. These filings requested revenue requirement increases of $133 million and $256 million for SDG&E and SoCalGas, respectively, over their 2015 revenue requirements. In February 2015, the CPUC issued a scoping memo setting the schedule for the proceeding, including the issuance of a proposed decision by the end of 2015.
	In May 2013, the CPUC approved a final decision in the California Utilities’ 2012 GRC (Final 2012 GRC Decision). The Final 2012 GRC Decision was effective retroactive to January 1, 2012, and SDG&E and SoCalGas recorded the cumulative earnings effect of the retroactive application of the Final 2012 GRC Decision of $69 million and $37 million, respectively, in the second quarter of 2013. For SDG&E and SoCalGas, respectively, these amounts included an incremental earnings impact of $52 million and $25 million related to 2012 and $17 million and $12 million related to the first quarter of 2013.
	The amount of revenue associated with the retroactive period is being recovered in SDG&E’s rates over a 28-month period beginning in September 2013, and in SoCalGas’ rates over a 31-month period beginning in June 2013. At December 31, 2014, SDG&E reported on its Consolidated Balance Sheet $162 million as a regulatory asset, all classified as current, representing the retroactive revenue from the Final 2012 GRC Decision to be recovered by SDG&E in rates through December 2015. At December 31, 2014, SoCalGas reported on its Consolidated Balance Sheet a regulatory asset of $52 million, all classified as current, representing the retroactive revenue from the Final GRC Decision to be recovered in rates through December 2015.
	CPUC Cost of Capital
	A CPUC cost of capital proceeding determines a utility’s authorized capital structure and authorized rate of return on rate base (ROR), which is a weighted average of the authorized returns on debt, preferred stock, and common equity (return on equity or ROE), weighted on a basis consistent with the authorized capital structure. The authorized ROR is the rate that the California Utilities are authorized to use in establishing rates to recover the cost of debt and equity used to finance their investment in CPUC-regulated electric distribution and generation as well as natural gas distribution, transmission and storage assets.
	In addition, a cost of capital proceeding also addresses the automatic cost of capital adjustment mechanism (CCM) which applies market-based benchmarks to determine whether an adjustment to the authorized ROR is required during the interim years between cost of capital proceedings. The market-based benchmark for SDG&E’s and SoCalGas’ CCM is the 12-month average monthly A-rated utility bond index, as published by Moody’s for the 12-month period of October 1st through September 30th (CCM Period) of each calculation year. In the last cost of capital proceeding, SDG&E’s and SoCalGas’ CCM benchmark rate was set at 4.24 percent. If at the end of the CCM Period the monthly average benchmark rate falls outside of the established range of 3.24 percent to 5.24 percent, SDG&E’s and SoCalGas’ authorized ROE would be adjusted, upward or downward, by one-half of the difference between the 12-month average and the benchmark rate. In addition, the authorized recovery rate for SDG&E’s and SoCalGas’ cost of debt and preferred stock would be adjusted to their respective actual weighted average costs, with no change to the authorized capital structure. All three adjustments with the new rate would become effective on January 1st of the following year in which the benchmark range was exceeded. For the twelve-month period ended September 30, 2014, the 12-month average of monthly Moody’s A-rated utility bond index was 4.46 percent.
	The CCM only applies during the intervening years between scheduled cost of capital proceedings. In the year the cost of capital proceeding is scheduled, the cost of capital proceeding takes precedence over CCM and will set new rates for the following year.
	In December 2014, the CPUC granted both SDG&E and SoCalGas an extension of their filing deadlines for their next cost of capital applications by one year, from April 2015 to April 2016. The CPUC also extended the current CCM until the April 2016 filing date. The one year extension was made in response to a joint request by SDG&E, SoCalGas, Pacific Gas and Electric Company (PG&E) and Edison with the CPUC in November 2014.
	SDG&E’s current CPUC-authorized ROR is 7.79 percent and SoCalGas’ current CPUC-authorized ROR is 8.02 percent based on their authorized capital structures as follows:
	COST OF CAPITAL AND AUTHORIZED RATE STRUCTURE
	SDG&E				SoCalGas
	Authorized weighting	Authorized rate of recovery	Weighted authorized ROR		Authorized weighting	Authorized rate of recovery	Weighted authorized ROR
	45.25%	5.00%	2.26%	Long-Term Debt	45.60%	5.77%	2.63%
	2.75%	6.22%	0.17%	Preferred Stock	2.40%	6.00%	0.14%
	52.00%	10.30%	5.36%	Common Equity	52.00%	10.10%	5.25%
	100.00%		7.79%		100.00%		8.02%
	SDG&E files separately with the FERC for authorized ROE on FERC-regulated electric transmission operations and assets as described below in “Federal Energy Regulatory Commission (FERC) Formulaic Rate Matters”.
	Natural Gas Pipeline Operations Safety Assessments
	Various regulatory agencies, including the CPUC, are evaluating natural gas pipeline safety regulations, practices and procedures. In February 2011, the CPUC opened a forward-looking rulemaking proceeding to examine what changes should be made to existing pipeline safety regulations for California natural gas pipelines. The California Utilities are parties to this proceeding.
	In June 2011, the CPUC directed SoCalGas, SDG&E, PG&E and Southwest Gas to file comprehensive implementation plans to test or replace natural gas transmission pipelines located in populated areas that have not been pressure tested. The California Utilities filed their Pipeline Safety Enhancement Plan (PSEP) with the CPUC in August 2011. In their 2011 filing with the CPUC, the California Utilities estimated the total cost for Phase 1 of the two-phase plan to be $3.1 billion ($2.5 billion for SoCalGas and $600 million for SDG&E) over the 10-year period of 2012 to 2022. As a result of on-going efforts since this original filing, the California Utilities have been able to eliminate over two hundred miles of pipeline from the testing scope and have revised their total estimated cost for Phase 1 to $2.1 billion ($1.6 billion for SoCalGas and $500 million for SDG&E). The California Utilities requested that the incremental capital investment required as a result of any approved plan be included in rate base and that cost recovery be allowed for any other incremental cost not eligible for rate-base recovery.
	In April 2012, the CPUC transferred the PSEP to the Triennial Cost Allocation Proceeding (TCAP) and authorized SDG&E and SoCalGas to establish regulatory accounts to record the incremental costs of initiating the PSEP prior to a final decision on the PSEP.
	Also in April 2012, the CPUC issued a decision expanding the scope of the rulemaking proceeding to incorporate the provisions of California Senate Bill (SB) 705, which requires gas utilities to develop and implement a plan for the safe and reliable operation of their gas pipeline facilities. SDG&E and SoCalGas submitted their pipeline safety plans in June 2012. The CPUC decision also orders the utilities to undergo independent management and financial audits to assure that the utilities are fully meeting their safety responsibilities. The CPUC’s Safety and Enforcement Division will select the independent auditors and will oversee the audits. A schedule for the audits has not been established. In December 2012, the CPUC issued a final decision accepting the utilities’ pipeline safety plans filed pursuant to SB 705.
	In June 2014, the CPUC issued a final decision in the TCAP proceeding addressing SDG&E’s and SoCalGas’ PSEP. Specifically, the decision:
	approved the utilities’ model for implementing PSEP;
	approved a process, including a reasonableness review, to determine the amount that the utilities will be authorized to recover from ratepayers for the interim costs incurred through the date of the final decision to implement PSEP, which is recorded in the regulatory accounts authorized by the CPUC as noted above;
	approved balancing account treatment, subject to a reasonableness review, for incremental costs yet to be incurred to implement PSEP; and
	established the criteria to determine the amounts that would not be eligible for cost recovery, including:
	certain costs incurred or to be incurred searching for pipeline test records,
	the cost of pressure testing pipelines installed after July 1, 1961 for which the company has not found sufficient records of testing, and
	any undepreciated balances for pipelines installed after 1961 that were replaced due to insufficient documentation of pressure testing.
	As a result of this decision, SoCalGas recorded an after-tax earnings charge of $5 million in 2014 for costs incurred in prior periods for which SoCalGas was disallowed recovery. After taking the amounts disallowed for recovery into consideration, as of December 31, 2014, SDG&E and SoCalGas have recorded PSEP costs of $2 million and $85 million, respectively, in the CPUC-authorized regulatory account. In regard to requesting recovery from customers for PSEP costs incurred and recorded in accordance with the TCAP decision, SDG&E and SoCalGas are authorized to file an application with the CPUC for recovery of such costs up to the date of the TCAP decision and then annually for costs incurred through the end of each calendar year beginning with the period ending December 31, 2015. SoCalGas and SDG&E currently expect to be able to file such applications by the third quarter of the year following and would expect a decision from the CPUC approximately 12 to 18 months following the date of the application (i.e. a decision on the recovery of costs recorded in the PSEP regulatory accounts as of December 31, 2015 would be expected by mid-2017). In response to this significant delay in receiving the authority to recover PSEP costs incurred from customers, in October 2014, SDG&E and SoCalGas filed a request with the CPUC for authority to recover PSEP costs from customers as incurred, subject to refund pending the results of a reasonableness review by the CPUC, instead of in the subsequent year. In December 2014, SDG&E and SoCalGas filed an application with the CPUC for recovery of $0.1 million and $46 million, respectively, in costs recorded in the regulatory account through June 11, 2014. We requested a decision in 2015.
	In July 2014, the ORA and TURN filed a joint application for rehearing of the CPUC’s June 2014 final decision. The ORA and TURN alleged that the CPUC made a legal error in directing that ratepayers, not shareholders, be responsible for the costs associated with testing or replacing transmission pipelines that were installed between January 1, 1956 and July 1, 1961 for which the California Utilities do not have a record of a pressure test. In November 2014, the CPUC denied the ORA and TURN request for rehearing of the decision adopting the PSEP. In December 2014, ORA and TURN sought rehearing of the CPUC’s decision on rehearing. In late December 2014, SoCalGas and SDG&E filed their opposition to this second application for rehearing, and are continuing to implement PSEP in accordance with the June 2014 CPUC decision.
	Southern Gas System Reliability Project
	In December 2013, SoCalGas and SDG&E filed a joint application with the CPUC seeking authority to recover the full cost of the Southern Gas System Reliability Project. Also known as the North-South Gas Project, the project will enhance reliability on the southern portions of the California Utilities’ integrated natural gas transmission system (Southern System). The estimated cost of the project, as originally filed, is between $800 million to $850 million. As proposed, the project consists of three components: 1) constructing an approximately 60-mile, 36-inch natural gas transmission pipeline between the SoCalGas Adelanto compressor station and the Moreno pressure limiting station; 2) upgrading the Adelanto compressor station; and 3) constructing an approximately 31-mile, 36-inch pipeline from the Moreno pressure limiting station to a pressure limiting station in Whitewater. In November 2014, the California Utilities revised the scope of the proposed project to only include connecting the Adelanto compressor station and Moreno pressure limiting station with approximately 65 miles of 36-inch pipeline and upgrading the Adelanto compressor station, and eliminating the Moreno-Whitewater pipeline. As a result of the revised scope of the project, the California Utilities assessed the estimated cost of the revised project and confirmed the original cost estimate of $800 million to $850 million, while still providing almost all of the benefits for customers. Given the revised project scope, an updated schedule in this proceeding is currently being developed. Depending upon this updated schedule and subject to environmental permitting and approval by the CPUC, we expect the project to be in service by the end of 2019.
	Utility Incentive Mechanisms
	The CPUC applies performance-based measures and incentive mechanisms to all California investor-owned utilities, under which the California Utilities have earnings potential above authorized base margins if they achieve or exceed specific performance and operating goals. Generally, for performance-based awards, if performance is above or below specific benchmarks, the utility is eligible for financial awards or subject to financial penalties. SDG&E has incentive mechanisms associated with:
	operational incentives
	energy efficiency
	SoCalGas has incentive mechanisms associated with:
	energy efficiency
	natural gas procurement
	unbundled natural gas storage and system operator hub services
	Incentive awards are included in our earnings when we receive any required CPUC approval of the award. We would record penalties for results below the specified benchmarks in earnings when we believe it is more likely than not that the CPUC would assess a penalty.
	Energy Efficiency
	The CPUC established incentive mechanisms that are based on the effectiveness of energy efficiency programs. In December 2012, the CPUC issued a final decision adopting a mechanism for the 2010–2012 program cycle and approving shareholder awards of $3.3 million for SDG&E and $2.7 million for SoCalGas for their energy efficiency program performance in 2010 under the mechanism. The decision established an annual process for the utilities to obtain awards for their performance in 2011 and 2012.
	In December 2013, the CPUC awarded $3.1 million to SoCalGas and $3.9 million to SDG&E for their 2011 program year results. In December 2014, the CPUC approved awards to SoCalGas and SDG&E of $5.9 million and $7.5 million, respectively, for program years 2012 and 2013. Of these amounts, SoCalGas and SDG&E will receive initial 2013 program awards of $1.5 million and $2.5 million, respectively, and the CPUC will address the remaining 2013 program awards in 2015.
	Unbundled Natural Gas Storage and System Operator Hub Services
	The CPUC has established a revenue sharing mechanism, effective through 2015, which provides for the sharing between ratepayers and SoCalGas (shareholders) of the net revenues generated by SoCalGas’ unbundled natural gas storage and system operator hub services. Annual net revenues (revenues less allocated service costs) under the mechanism are shared on a graduated basis, as follows:
	the first $15 million of net revenue to be shared 90 percent ratepayers/10 percent shareholders;
	the next $15 million of net revenue to be shared 75 percent ratepayers/25 percent shareholders;
	all additional net revenues to be shared evenly between ratepayers and shareholders; and
	the maximum total annual shareholder-allocated portion of the net revenues cannot exceed $20 million.
	SoCalGas is seeking to extend the mechanism through at least 2019, but revise the sharing to 60 percent ratepayers/40 percent shareholders to reflect changes in the market for storage services. The current annual shareholder earnings cap of $20 million would remain in place.
	Natural Gas Procurement
	The California Utilities procure natural gas on behalf of their core natural gas customers. The CPUC has established incentive mechanisms to allow the California Utilities the opportunity to share in the savings and/or costs from buying natural gas for their core customers at prices below or above monthly market-based benchmarks. SoCalGas procures natural gas for SDG&E’s core natural gas customers’ requirements. SoCalGas’ gas cost incentive mechanism (GCIM) is applied on the combined portfolio basis.
	The CPUC issued final decisions in 2014, 2013 and 2012 approving GCIM awards for SoCalGas of $5.8 million, $5.4 million and $6.2 million, respectively, for the 12-month periods ending March 31, 2013, 2012 and 2011, respectively. SoCalGas filed an application with the CPUC for approval of a $13.7 million GCIM award for natural gas procured for its core customers during the 12-month period ending March 31, 2014. In February 2015, the CPUC issued a final decision approving the $13.7 million GCIM award as requested by SoCalGas. SoCalGas will recognize this award in its financial results for the first quarter of 2015.
	Operational Incentives
	The CPUC may establish operational incentives and associated performance benchmarks as part of a general rate case or cost of service proceeding. In the California Utilities’ Final 2012 GRC Decision described above, SDG&E was directed to establish a performance measure and incentive for electric reliability. In September 2014, the CPUC approved SDG&E’s proposed mechanism, which will apply to calendar year 2015 and be considered in the 2016 GRC. The CPUC did not establish any operational incentives for SoCalGas in the Final 2012 GRC Decision.
	SDG&E MATTERS
	SONGS
We discuss regulatory and other matters related to SONGS in Note 13.
Power Procurement and Resource Planning
Background—Electric Industry Regulation
California’s legislative response to the 2000 – 2001 energy crisis resulted in the California Department of Water Resources (DWR) purchasing a substantial portion of power for California’s electricity users. In 2001, the DWR entered into long-term contracts with suppliers, including Sempra Natural Gas, to provide power for the utility procurement customers of each of the California investor-owned utilities (IOUs), including SDG&E. The CPUC allocates the power and its administrative responsibility, including collection of power contract costs from utility customers, among the IOUs. The last of these power contracts expired in 2013, with one remaining transportation contract allocated to SDG&E that will expire in 2018.
Renewable Energy
SDG&E is subject to the Renewables Portfolio Standard (RPS) Program administered by both the CPUC and the California Energy Commission, which requires each California utility to procure 33 percent of its annual electric energy requirements from renewable energy sources by 2020, with an average of 20 percent required from January 1, 2011 to December 31, 2013; 25 percent by December 31, 2016; and 33 percent by December 31, 2020. The CPUC began a rulemaking proceeding in May 2011 to address the implementation of the 33% RPS Program.
The 33% RPS Program contains flexible compliance mechanisms that can be used to comply with or meet the 33% RPS Program mandates in 2011 and beyond. The mechanisms provide for a CPUC waiver under certain conditions, including: 1) a finding of inadequate transmission; 2) delays in the start-up of commercial operations of renewable energy projects due to permitting or interconnection; or 3) unexpected curtailment by an electric system balancing authority, such as the California ISO.
SDG&E continues to procure renewable energy supplies to achieve the 33% RPS Program requirements. A substantial number of these supply contracts, however, are contingent upon many factors, including:
access to electric transmission infrastructure;
timely regulatory approval of contracted renewable energy projects;
the renewable energy project developers’ ability to obtain project financing and permitting; and
successful development and implementation of the renewable energy technologies.
In August 2014, SDG&E made a required filing with the CPUC indicating that its procurement of renewable energy during the period January 1, 2011 through December 31, 2013 exceeded the 20-percent minimum amount required by RPS. SDG&E believes it will be able to comply with the 33% RPS Program requirements based on its contracting activity and, if necessary, application of the flexible compliance mechanisms. SDG&E’s failure to comply with the RPS Program requirements could subject it to CPUC-imposed penalties, which could materially affect its business, cash flows, financial condition, results of operations and/or prospects. The limit on the total amount of penalties for failure to comply with the RPS requirements is $75 million for the first compliance period (2011-2013); $75 million for the second compliance period (2014-2016); $100 million for the third compliance period (2017-2020); and $25 million for each annual compliance period beginning in 2021.
Cleveland National Forest Transmission Projects
SDG&E filed an application with the CPUC in October 2012 for a permit to construct various transmission replacement projects in and around the Cleveland National Forest (CNF). The proposed projects will replace and fire-harden five existing transmission lines and six existing distribution lines at an estimated cost of between $400 million and $450 million. As directed by the CPUC, SDG&E filed an amended application in June 2013 to provide notice of certain alternatives proposed by the U.S. Forest Service (USFS) in connection with SDG&E’s request for a Master Special Use Permit (MSUP). USFS approval of the MSUP will establish land rights and conditions for SDG&E’s continued operation and maintenance of facilities located within the CNF. CPUC approval is not required for the MSUP, even though construction of the projects is subject to review by both the USFS and CPUC. A draft environmental impact report (EIR/EIS), developed jointly by the CPUC and USFS, was issued in September 2014 and a final EIR/EIS is expected in early 2015. SDG&E currently expects a CPUC decision approving the transmission projects in the second half of 2015 and then expects the various phases of this project to be placed in service starting in 2016 and continuing through the end of the project in 2019.
Sycamore-Peñasquitos Transmission Project
In March 2014, the CAISO selected SDG&E, as a result of a competitive bid process, to construct the Sycamore-Peñasquitos 230-kilovolt (kV) transmission project, which will provide a 16.7-mile transmission connection between SDG&E’s Sycamore Canyon and Peñasquitos substations. In July 2014, the CPUC notified SDG&E that the application requesting a Certificate of Public Convenience and Necessity (CPCN) to construct the line, which was filed with the CPUC in April 2014, is complete. The estimated $120 million to $150 million project was identified by the CAISO and a state task force as necessary to ensure grid reliability given the closure of SONGS. The project will also serve to strengthen renewable energy infrastructure in the region. In October 2014, SDG&E filed a request with FERC seeking, among other things, a 100 basis point ROE adder for this project. We expect a FERC decision on this filing in 2015. SDG&E expects a CPUC decision approving the project in the first half of 2016, with the line expected to be in service in mid-2017.
South Orange County Reliability Enhancement
SDG&E filed an application with the CPUC in May 2012 requesting a CPCN for the South Orange County Reliability Enhancement project. The purpose of the project is to enhance the capacity and reliability of SDG&E’s electric service to the south Orange County area. The proposed project primarily includes replacing and upgrading approximately eight miles of transmission lines and rebuilding and upgrading a substation at an existing site. SDG&E expects a draft environmental report to be issued in early 2015 and a final CPUC decision approving the estimated $400 million to $500 million project in the first half of 2016. SDG&E obtained approval for the project from the CAISO in May 2011. As the project is planned in phases, SDG&E currently expects the entire project to be in service in 2020.
South Bay Substation and Relocation Project
SDG&E filed an application in 2010 with the CPUC for a permit to construct a new substation, the Bay Boulevard substation, to replace the aging and obsolete South Bay substation to accommodate regional energy demands. The existing substation will be demolished when the Bay Boulevard substation has been constructed, energized and all transmission lines have been transferred. In October 2013, the CPUC approved SDG&E’s permit to construct the Bay Boulevard substation at SDG&E’s proposed site. The project is estimated at $145 million to $175 million. In March 2014, the California Coastal Commission approved the coastal development permit for the project, subject to certain additional environmental enhancements. In July 2014, SDG&E filed a petition with the CPUC to request modifications to the prior CPUC decision to authorize the additional construction activities required by the coastal development permit. In January 2015, the CPUC issued a decision approving the petition for modification. SDG&E is in the process of obtaining the remaining approvals and permits required to begin construction. SDG&E currently expects the project to be in service in 2017.
Federal Energy Regulatory Commission (FERC) Formulaic Rate Matters
In February 2013, SDG&E submitted its Electric Transmission Formula Rate (TO4) filing with the FERC to set the rate making methodology and rate of return for SDG&E’s FERC-regulated electric transmission operations and assets for a multi-year period beginning September 1, 2013. The TO4 filing proposed a FERC ROE of 11.3 percent and requested: 1) rates to be determined by a base period of historical costs and a forecast of capital investments and 2) a true-up period similar to balancing account treatment that is designed to provide SDG&E earnings of no more and no less than its actual cost of service including its authorized return on investment. In June and July 2013, the FERC issued orders accepting the filing, subject to refund, and established settlement and hearing procedures, with rates being effective September 1, 2013.
On January 31, 2014, SDG&E filed an uncontested multi-party settlement at the FERC regarding the TO4 filing. The settlement, approved by FERC in May 2014, will be in effect through December 31, 2018, is subject to a one-time right of termination by any party, and established a 10.05 percent ROE. The settlement also requires SDG&E to make annual information filings on December 1 of a given year to update rates for the following calendar year. SDG&E also has the right to file for any ROE incentives that might apply under FERC rules. SDG&E’s debt to equity ratio will be set annually based on the actual ratio at the end of each year.
Energy Resource Recovery Account (ERRA)
The ERRA is the regulatory balancing account that SDG&E uses to recover the electric fuel and purchased power costs it incurs to provide energy to its bundled service customers. SDG&E files an application with the CPUC each year to establish the ERRA revenue requirement needed for the following calendar year. Additionally, to the extent the ERRA balance exceeds a certain tolerance or “ERRA Trigger”, SDG&E must file an application to adjust its rates upward or downward, as applicable, to address the under- or overcollected ERRA balance, respectively. In February 2014, the CPUC issued a decision granting SDG&E authority to increase rates to recover an ERRA Trigger revenue requirement of $221 million, which rate increase was effective on April 1, 2014 and will continue through December 31, 2015. In May 2014, the CPUC issued a final decision approving SDG&E’s proposed 2014 ERRA revenue requirement of $1.23 billion, an increase of $242 million compared to the 2013 ERRA revenue requirement of $988 million. SDG&E implemented the increased revenue requirement on August 1, 2014.
Excess Wildfire Claims Cost Recovery
In August 2009, SDG&E and SoCalGas filed an application, along with other related filings, with the CPUC proposing a new framework and mechanism for the future recovery of all wildfire-related expenses for claims, litigation expenses and insurance premiums that are in excess of amounts authorized by the CPUC for recovery in distribution rates. In December 2012, the CPUC issued a final decision that ultimately did not approve the proposed framework for the utilities but allowed SDG&E to maintain its authorized memorandum account so that SDG&E may file applications with the CPUC requesting recovery of amounts properly recorded in the memorandum account at a later time, subject to reasonableness review.
In February 2014, the Presiding Judge assigned by the FERC to SDG&E’s annual Electric Transmission Formula Rate filing (TO3 Cycle 6) issued an Initial Decision and an Order on Summary Judgment which authorizes SDG&E to recover all of the costs incurred and allocated to SDG&E’s FERC-regulated operations for the 12-month period ended March 31, 2012, resulting from settlement activities for 2007 wildfire claims. In connection with this proceeding, the CPUC filed an appeal in the Ninth Circuit Court of Appeal of an earlier decision by the FERC denying the CPUC’s request to postpone the FERC proceeding pending CPUC action on cost recovery of the excess wildfire costs. The FERC has sought dismissal of the CPUC’s appeal on procedural grounds. The Court of Appeal has not yet ruled on the merits.
SDG&E intends to pursue recovery of the costs it has incurred for settlement activities associated with the 2007 wildfire claims allocated to SDG&E’s CPUC-regulated operations by filing an application with the CPUC in 2015. SDG&E will continue to assess the potential for recovery of these costs in rates. We discuss the impact should SDG&E conclude that recovery in rates is no longer probable in “Legal Proceedings — SDG&E — 2007 Wildfire Litigation” in Note 15. We discuss how we assess the probability of recovery of our regulatory assets in Note 1.
SOCALGAS MATTERS
Advanced Metering Infrastructure
In November 2011, the ORA and TURN filed a joint petition requesting that the CPUC reconsider its prior approval of SoCalGas’ advanced metering infrastructure (AMI) project and stay AMI deployment while the CPUC considered the request. In June 2014, the CPUC denied the ORA/TURN petition, and SoCalGas is continuing its deployment of AMI pursuant to the April 2010 CPUC decision approving the project.

Notes to Consolidated Financial Statements [Abstract]
Commitments and Contingencies	NOTE 15. COMMITMENTS AND CONTINGENCIES
	LEGAL PROCEEDINGS
	We accrue losses for a legal proceeding when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. However, the uncertainties inherent in legal proceedings make it difficult to estimate with reasonable certainty the costs and effects of resolving these matters. Accordingly, actual costs incurred may differ materially from amounts accrued, may exceed applicable insurance coverage and could materially adversely affect our business, cash flows, results of operations, financial condition and prospects. Unless otherwise indicated, we are unable to estimate reasonably possible losses in excess of any amounts accrued.
	At December 31, 2014, Sempra Energy’s accrued liabilities for legal proceedings, including associated legal fees and costs of litigation, on a consolidated basis, were $68 million. At December 31, 2014, accrued liabilities for legal proceedings for SDG&E and SoCalGas were $49 million and $12 million, respectively.
	SDG&E
	2007 Wildfire Litigation
	In October 2007, San Diego County experienced several catastrophic wildfires. Reports issued by the California Department of Forestry and Fire Protection (Cal Fire) concluded that two of these fires (the Witch and Rice fires) were SDG&E “power line caused” and that a third fire (the Guejito fire) occurred when a wire securing a Cox Communications’ (Cox) fiber optic cable came into contact with an SDG&E power line “causing an arc and starting the fire.”
	A September 2008 staff report issued by the CPUC’s Consumer Protection and Safety Division, now known as the Safety and Enforcement Division (CPSD), reached substantially the same conclusions as the Cal Fire reports, but also contended that the power lines involved in the Witch and Rice fires and the lashing wire involved in the Guejito fire were not properly designed, constructed and maintained. In April 2010, proceedings initiated by the CPUC to determine if any of its rules were violated were settled with SDG&E’s payment of $14.75 million.
	Numerous parties have sued SDG&E and Sempra Energy in San Diego County Superior Court seeking recovery of unspecified amounts of damages, including punitive damages, from the three fires. They assert various bases for recovery, including inverse condemnation based upon a California Court of Appeal decision finding that another California investor-owned utility was subject to strict liability, without regard to foreseeability or negligence, for property damages resulting from a wildfire ignited by power lines. SDG&E has resolved all but five of these lawsuits. Four of these remaining cases have been scheduled for damages-only trials in 2015, where the value of any compensatory damages resulting from the fires will be determined.
	SDG&E’s settled claims and defense costs have exceeded its $1.1 billion of liability insurance coverage for the covered period and the $824 million recovered from third party contractors and Cox. SDG&E has settled all of the approximately 19,000 claims brought by homeowner insurers for damage to insured property relating to the three fires. Under the settlement agreements, SDG&E agreed to pay 57.5 percent of the approximately $1.6 billion paid or reserved for payment by the insurers to their policyholders and received an assignment of the insurers’ claims against other parties potentially responsible for the fires. Through December 31, 2014, SDG&E has expended $483 million in excess of amounts covered by insurance and amounts recovered from third parties to pay for the settlement of wildfire claims and related costs.
	The wildfire litigation also includes claims of non-insurer plaintiffs for damage to uninsured and underinsured structures, business interruption, evacuation expenses, agricultural damage, emotional harm, personal injuries and other losses. SDG&E has now settled almost all of these claims of the approximately 6,500 plaintiffs for a total of approximately $1.3 billion. Substantially all of the remaining plaintiffs have submitted settlement demands and damage estimates, which total approximately $60 million. SDG&E does not expect additional plaintiffs to file lawsuits given the applicable statutes of limitation, but does expect to receive additional settlement demands and damage estimates from existing plaintiffs until those cases are resolved. SDG&E has established reserves for the wildfire litigation as we discuss below.
	SDG&E has concluded that it is probable that it will be permitted to recover in rates a substantial portion of the costs incurred to resolve wildfire claims in excess of its liability insurance coverage and the amounts recovered from third parties. Accordingly, although such recovery will require future regulatory approval, at December 31, 2014, Sempra Energy and SDG&E have recorded assets of $373 million in Other Regulatory Assets (long-term) on their Consolidated Balance Sheets, including $366 million related to CPUC-regulated operations, which represents the amount substantially equal to the aggregate amount it has paid or reserved for payment for the resolution of wildfire claims and related costs in excess of its liability insurance coverage and amounts recovered from third parties.
	SDG&E will continue to gather information to evaluate and assess the remaining wildfire claims and the likelihood, amount and timing of related recoveries in rates and will make appropriate adjustments to wildfire reserves and the related regulatory assets as additional information becomes available. Should SDG&E conclude that recovery in rates is no longer probable, SDG&E will record a charge against earnings at the time such conclusion is reached. If SDG&E had concluded that the recovery of regulatory assets related to CPUC-regulated operations was no longer probable or was less than currently estimated at December 31, 2014, the resulting after-tax charge against earnings would have been up to approximately $217 million. Recovery of these costs from customers will require future regulatory actions, and a failure to obtain substantial or full recovery, or any negative assessment of the likelihood of recovery, would likely have a material adverse effect on Sempra Energy’s and SDG&E’s businesses, financial condition, cash flows, results of operations and prospects.
	We provide additional information about excess wildfire claims cost recovery and related CPUC actions in Note 14 and discuss how we assess the probability of recovery of our regulatory assets in Note 1.
	Sunrise Powerlink Electric Transmission Line
	In February 2011, opponents of the Sunrise Powerlink, a 500-kV electric transmission line between the Imperial Valley and the San Diego region that was energized and placed in service in June 2012, filed a lawsuit in Sacramento County Superior Court against the State Water Resources Control Board and SDG&E alleging that the water quality certification issued by the Board under the Federal Clean Water Act violated the California Environmental Quality Act. The Superior Court denied the plaintiffs’ petition in July 2012, and the plaintiffs have appealed.
	A claim for additional compensation was submitted in 2013 by one of SDG&E’s contractors on the Sunrise Powerlink project. The contractor was awarded the transmission line overhead and underground construction contract on a fixed-fee basis of $456 million after agreed-upon amendments. The contractor asserted that it was owed additional compensation above the fixed-fee portion of the contract. In May 2013, the contractor filed claims totaling $180 million, including one in San Diego County for the sum of $99 million and the other in Imperial County for the sum of $81 million, seeking foreclosure of previously filed mechanics liens. In October 2013, the contractor served a Demand for Arbitration pursuant to contractual provisions and SDG&E counterclaimed against the contractor. In December 2014, SDG&E and the contractor settled their claims with SDG&E agreeing to pay the contractor $65 million as compensation for additional costs incurred by the contractor for the work performed.
	September 2011 Power Outage
	In September 2011, a power outage lasting approximately 12 hours affected millions of people from Mexico to southern Orange County, California. Within several days of the outage, several SDG&E customers filed a class action lawsuit in Federal District Court in San Diego against Arizona Public Service Company, Pinnacle West Capital Corporation and SDG&E alleging that the companies failed to prevent the outage. The lawsuit sought recovery of unspecified amounts of damages, including punitive damages. In July 2012, the court granted SDG&E’s motion to dismiss the punitive damages request and dismissed Arizona Public Service Company and Pinnacle West Capital Corporation from the lawsuit. In September 2013, the court granted SDG&E’s motion for summary judgment and dismissed the lawsuit. In October 2013, the plaintiffs appealed the court’s dismissal of their action. In January 2015, SDG&E settled this claim for an insignificant amount and the appeal and lawsuit have been dismissed.
	The FERC and North American Electric Reliability Corporation (NERC) Staff conducted a joint inquiry to determine the cause of the power failure and issued a report in May 2012 regarding their findings. In January 2014, FERC Enforcement Staff issued a Staff Notice of Alleged Violations, in which FERC Enforcement Staff alleged violations of various Reliability Standards by several entities. FERC Enforcement Staff did not allege or find any violations by SDG&E.
	Smart Meters Patent Infringement Lawsuit
	In October 2011, SDG&E was sued by a Texas design and manufacturing company in Federal District Court, Southern District of California, and later transferred to the Federal District Court, Western District of Oklahoma, alleging that SDG&E’s recently installed smart meters infringed certain patents. The meters were purchased from a third party vendor that has agreed to defend and indemnify SDG&E. The lawsuit seeks injunctive relief and recovery of unspecified amounts of damages.
	Lawsuit Against Mitsubishi Heavy Industries, Ltd.
	On July 18, 2013, SDG&E filed a lawsuit in the Superior Court of California in the County of San Diego against Mitsubishi Heavy Industries, Ltd., Mitsubishi Nuclear Energy Systems, Inc., and Mitsubishi Heavy Industries America, Inc. (collectively MHI). The lawsuit seeks to recover damages SDG&E has incurred and will incur related to the design defects in the steam generators MHI provided to the SONGS nuclear power plant. The lawsuit asserts a number of causes of action, including fraud, based on the representations MHI made about its qualifications and ability to design generators free from defects of the kind that resulted in the permanent shutdown of the plant and further seeks to set aside the contractual limitation of damages that MHI has asserted. On July 24, 2013, MHI removed the lawsuit to the United States District Court for the Southern District of California and on August 8, 2013, MHI moved to stay the proceeding pending resolution of the dispute resolution process involving MHI and Edison arising from their contract for the purchase and sale of the steam generators. On October 16, 2013, Edison initiated an arbitration proceeding against MHI seeking damages stemming from the failure of the replacement steam generators. In late December 2013, MHI answered and filed a counter-claim against Edison. On March 14, 2014, MHI’s motion to stay the United States District Court proceeding was granted with instructions that require the parties to allow SDG&E to participate in the ongoing Edison/MHI arbitration. As a result, SDG&E is now participating in the arbitration as a claimant and respondent.
	Investment in Wind Farm
	In 2011, the CPUC and FERC approved SDG&E’s estimated $285 million tax equity investment in a wind farm project and its purchase of renewable energy credits from that project. SDG&E’s contractual obligations to both invest in the Rim Rock wind farm and to purchase renewable energy credits from the wind farm under the power purchase agreement are subject to the satisfaction of certain conditions which, if not achieved, would allow SDG&E to terminate the power purchase agreement and not make the investment. In December 2013, SDG&E received a closing notice from the project developer indicating that all such conditions had been met. SDG&E responded to the closing notice asserting that the contractual conditions had not been satisfied. On December 19, 2013, SDG&E filed a complaint against the project developer in San Diego Superior Court, asking that the court determine that SDG&E is entitled to terminate both the investment contract and the power purchase agreement due to the project developer’s failure to satisfy certain conditions. The project developer filed a separate complaint against SDG&E in Montana state court asking that court to determine that SDG&E breached the investment contract and the power purchase agreement, and asking for several categories of relief, including requiring SDG&E to invest in the project, requiring SDG&E to continue performing under the power purchase agreement, and payment of damages.
	On January 27, 2014, the Montana court ordered SDG&E to continue making payments under the power purchase agreement pending a hearing on the project developer’s preliminary injunction motion. On March 14, 2014, SDG&E notified the project developer that the investment agreement expired by its own terms because a closing had not occurred by that date. The project developer is disputing SDG&E’s position. On March 28, 2014, SDG&E filed an amended complaint against the project developer in San Diego seeking damages and declaratory relief that SDG&E was entitled to terminate the power purchase agreement and to permit the investment agreement to expire. On April 25, 2014, the Montana court granted the project developer’s preliminary injunction motion to prevent SDG&E from terminating the power purchase agreement on the grounds that the project developer would be irreparably harmed if the payments were not made while the parties’ respective rights were being determined in the litigation. The court did not rule on the merits of the parties’ claims. On July 18, 2014, the Montana Supreme Court determined that the parties’ contractual agreement to resolve any disputes in San Diego was mandatory, and ordered that the Montana action be dismissed. The San Diego court has scheduled a trial for January 22, 2016.
	SoCalGas
	SoCalGas, along with Monsanto Co., Solutia, Inc., Pharmacia Corp. and Pfizer, Inc., are defendants in seven Los Angeles County Superior Court lawsuits filed beginning in April 2011 seeking recovery of unspecified amounts of damages, including punitive damages, as a result of plaintiffs’ exposure to PCBs (polychlorinated biphenyls). The lawsuits allege plaintiffs were exposed to PCBs not only through the food chain and other various sources but from PCB-contaminated natural gas pipelines owned and operated by SoCalGas. This contamination allegedly caused plaintiffs to develop cancer and other serious illnesses. Plaintiffs assert various bases for recovery, including negligence and products liability. SoCalGas has settled three of the seven lawsuits for an amount that is not significant.
	Sempra Mexico
	Permit Challenges and Property Disputes
	Sempra Mexico has been engaged in a long-running land dispute relating to property adjacent to its Energía Costa Azul LNG terminal near Ensenada, Mexico. Ownership of the adjacent property is not required by any of the environmental or other regulatory permits issued for the operation of the terminal. A claimant to the adjacent property has nonetheless asserted that his health and safety are endangered by the operation of the facility, and filed an action in the Federal Court challenging the permits. In February 2011, based on a complaint by the claimant, the municipality of Ensenada opened an administrative proceeding and sought to temporarily close the terminal based on claims of irregularities in municipal permits issued six years earlier. This attempt was promptly countermanded by Mexican federal and Baja California state authorities. No terminal permits or operations were affected as a result of these proceedings or events and the terminal has continued to operate normally. In the second quarter of 2014, the municipality of Ensenada dismissed the administrative proceeding, which is subject to an administrative appeal, pending for resolution before the Administrative Court of Baja California. Sempra Mexico expects additional Mexican court proceedings and governmental actions regarding the claimant’s assertions as to whether the terminal’s permits should be modified or revoked in any manner.
	The claimant also filed complaints in the federal Agrarian Court challenging the refusal of the Secretaría de la Reforma Agraria (now the Secretaría de Desarrollo Agrario, Territorial y Urbano, or SEDATU) in 2006 to issue a title to him for the disputed property. In November 2013, the Agrarian Court ordered that SEDATU issue the requested title and cause it to be registered. Both SEDATU and Sempra Mexico have challenged the rulings. Sempra Mexico expects additional proceedings regarding the claims, although such proceedings are not related to the permit challenges referenced above. The property claimant also filed a lawsuit in July 2010 against Sempra Energy in Federal District Court in San Diego seeking compensatory and punitive damages as well as the earnings from the Energía Costa Azul LNG terminal based on his allegations that he was wrongfully evicted from the adjacent property and that he has been harmed by other allegedly improper actions. Sempra Energy has disputed the claims and allegations in this lawsuit.
	Additionally, several administrative challenges are pending in Mexico before the Mexican environmental protection agency (SEMARNAT) and/or the Federal Tax and Administrative Courts seeking revocation of the environmental impact authorization (EIA) issued to Energía Costa Azul in 2003. These cases generally allege that the conditions and mitigation measures in the EIA are inadequate and challenge findings that the activities of the terminal are consistent with regional development guidelines. The Mexican Supreme Court decided to exercise jurisdiction over one such case, and in March 2014, issued a resolution denying the relief sought by the plaintiff on the grounds its action was not timely presented. A similar administrative challenge seeking to revoke the port concession for our marine operations at our Energía Costa Azul LNG terminal, which was filed with and rejected by the Mexican Communications and Transportation Ministry, remains on appeal in Mexican federal court as well.
	Two real property cases have been filed against Energía Costa Azul in which the plaintiffs seek to annul the recorded property titles for parcels on which the Energía Costa Azul LNG terminal is situated and to obtain possession of different parcels that allegedly sit in the same place; one of these cases was dismissed in September 2013 at the direction of the state appellate court. A third complaint was served in April 2013 seeking to invalidate the contract by which Energía Costa Azul purchased another of the terminal parcels, on the grounds the purchase price was unfair. Sempra Mexico expects further proceedings on the remaining two matters.
	Sempra Natural Gas
	Liberty Gas Storage, LLC (Liberty) received a demand for arbitration from Williams Midstream Natural Gas Liquids, Inc. (Williams) in February 2011 related to a sublease agreement. Williams alleges that Liberty was negligent in its attempt to convert certain salt caverns to natural gas storage and seeks damages of $56.7 million. Liberty filed a counterclaim alleging breach of contract in the inducement and seeks damages of more than $215 million.
	Other Litigation
	As described in Note 4, Sempra Energy holds a noncontrolling interest in RBS Sempra Commodities, a limited liability partnership in the process of being liquidated. RBS, our partner in the joint venture, was notified by the United Kingdom’s Revenue and Customs Department (HMRC) that it was investigating value-added tax (VAT) refund claims made by various businesses in connection with the purchase and sale of carbon credit allowances. HMRC advised RBS that it had determined that it had grounds to deny such claims by RBS related to transactions by RBS Sempra Energy Europe (RBS SEE), a former indirect subsidiary of RBS Sempra Commodities that was sold to JP Morgan. HMRC asserted that RBS was not entitled to reduce its VAT liability by VAT paid during 2009 because RBS knew or should have known that certain vendors in the trading chain did not remit their own VAT to HMRC. In September 2012, HMRC issued a protective assessment of £86 million for the VAT paid in connection with these transactions. In October 2014, RBS filed a Notice of Appeal of the September 2012 assessment with the First-tier Tribunal. As a condition of the appeal, RBS was required to pay the assessed amount. The payment also stops the accrual of interest that could arise should it ultimately be determined that RBS has a liability for some of the tax.
	In August 2007, the U.S. Court of Appeals for the Ninth Circuit issued a decision reversing and remanding certain FERC orders declining to provide refunds regarding short-term bilateral sales up to one month in the Pacific Northwest for the January 2000 to June 2001 time period. In December 2010, the FERC approved a comprehensive settlement previously reached by Sempra Energy and RBS Sempra Commodities with the State of California. The settlement resolved all issues with regard to sales between the California Department of Water Resources and Sempra Commodities in the Pacific Northwest, but potential claims may exist regarding sales in the Pacific Northwest between Sempra Commodities and other parties. The FERC is in the process of addressing these potential claims on remand. Pursuant to the agreements related to the formation of RBS Sempra Commodities, we have indemnified RBS should the liability from the final resolution of these matters be greater than the reserves related to Sempra Commodities. Pursuant to our agreement with the Noble Group Ltd., one of the buyers of RBS Sempra Commodities’ businesses, we have also indemnified Noble Americas Gas & Power Corp. and its affiliates for all losses incurred by such parties resulting from these proceedings as related to Sempra Commodities.
	We are also defendants in ordinary routine litigation incidental to our businesses, including personal injury, employment litigation, product liability, property damage and other claims. Juries have demonstrated an increasing willingness to grant large awards, including punitive damages, in these types of cases.
	CONTRACTUAL COMMITMENTS
	Natural Gas Contracts
	SoCalGas has the responsibility for procuring natural gas for both SDG&E’s and SoCalGas’ core customers in a combined portfolio. SoCalGas buys natural gas under short-term and long-term contracts for this portfolio. Purchases are from various producing regions in the southwestern U.S., U.S. Rockies, and Canada and are primarily based on published monthly bid-week indices.
	SoCalGas transports natural gas primarily under long-term firm interstate pipeline capacity agreements that provide for annual reservation charges, which are recovered in rates. SoCalGas has commitments with interstate pipeline companies for firm pipeline capacity under contracts that expire at various dates through 2028.
	Sempra Natural Gas’ and Sempra Mexico’s businesses have various natural gas purchase agreements to fuel natural gas-fired power plants and capacity agreements for natural gas storage and transportation.
	Sempra Natural Gas has an agreement for capacity on the Rockies Express pipeline through November 2019, as we discuss in Note 4. The capacity costs are offset by revenues from releases of the capacity contracted to third parties. Certain capacity release commitments totaling $22 million concluded during 2013, and contracting activity related to that capacity has not been sufficient to offset all of our capacity payments to Rockies Express. Including capacity released to others, Sempra Natural Gas’ obligation to Rockies Express for future capacity payments is expected to be $11 million in 2015, $14 million in each of 2016 and 2017, $34 million in 2018, and $67 million in 2019.

LNG Purchase Agreement
Sempra Natural Gas has a purchase agreement for the supply of LNG to the Energía Costa Azul terminal. The agreement is priced using a predetermined formula based on natural gas market indices. Although this contract specifies a number of cargoes to be delivered, under its terms, the customer may divert certain cargoes, which would reduce amounts paid under the contracts by Sempra Natural Gas. At December 31, 2014, the following LNG commitment amounts are based on if all cargoes under the contract were to be delivered:
$381 million in 2015
$552 million in 2016
$616 million in 2017
$674 million in 2018
$701 million in 2019
$7.6 billion in 2020 – 2029
The amounts above are based on forward prices of the index applicable to each contract from 2015 to 2024 and an estimated one percent escalation per year beyond 2024. The LNG commitment amounts above are based on Sempra Natural Gas’ commitment to accept the maximum possible delivery of cargoes under the agreement. Actual LNG purchases in 2014, 2013 and 2012 have been significantly lower than the maximum amount possible due to the customer electing to divert most cargoes as allowed by the agreement.
Purchased-Power Contracts
For 2015, SDG&E expects to meet its customer power requirements from the following resource types:
Long-term contracts: 35 percent (of which 30.2 percent is provided by renewable energy contracts expiring on various dates through 2041)
SDG&E-owned generation (including Palomar Energy Center, Miramar Energy Center, Desert Star Energy Center and Cuyamaca Peak Energy Plant) and tolling contracts (including OMEC): 57 percent
Spot market purchases: 8 percent
Chilquinta Energía and Luz del Sur also have purchased-power contracts, expiring on various dates extending through 2027, which cover most of the consumption needs of the companies’ customers. These commitments are included under Sempra Energy Consolidated in the table below.
At December 31, 2014, the estimated future minimum payments under long-term purchased-power contracts were:

-1	Excludes DWR-allocated contracts. Under an operating agreement with the DWR that expired at the end of 2013, SDG&E acted as a limited agent on behalf of the DWR in the administration of energy contracts, including natural gas procurement functions under the DWR contracts allocated to SDG&E's customers. The commodity costs associated with these contracts are not included in SDG&E's or Sempra Energy's Consolidated Statements of Operations.
Operating Leases
Sempra Energy Consolidated, SDG&E and SoCalGas have operating leases on real and personal property expiring at various dates from 2015 through 2054. Certain leases on office facilities contain escalation clauses requiring annual increases in rent ranging from two percent to six percent at Sempra Energy Consolidated, four percent to six percent at SDG&E, and two percent to five percent at SoCalGas. The rentals payable under these leases may increase by a fixed amount each year or by a percentage of a base year, and most leases contain extension options that we could exercise.
The California Utilities have an operating lease agreement for future acquisitions of fleet vehicles with an aggregate maximum lease limit of $150 million, $134 million of which has been utilized as of December 31, 2014.

Capital Leases
Power Purchase Agreements
SDG&E has three power purchase agreements with peaker plant facilities, two of which went into commercial operation in June 2010 and one of which went into commercial operation in 2014. All three are accounted for as capital leases. The entities that own the peaker plant facilities are VIEs of which SDG&E is not the primary beneficiary. As of December 31, 2014, capital lease obligations for these leases, each with a 25-year term, were valued at $233 million. SDG&E does not have any additional implicit or explicit financial responsibility related to these VIEs.
At December 31, 2014, the future minimum lease payments and present value of the net minimum lease payments under these capital leases for both Sempra Energy Consolidated and SDG&E were as follows:
FUTURE MINIMUM PAYMENTS – POWER PURCHASE AGREEMENTS

-2	Amount necessary to reduce net minimum lease payments to present value at the inception of the leases.
-3	Includes $4 million in Current Portion of Long-Term Debt and $229 million in Long-Term Debt on Sempra Energy’s and SDG&E’s Consolidated Balance Sheets at December 31, 2014.
The annual amortization charge for the power purchase agreements was $3 million in 2014 and $2 million in each of 2013 and 2012.
Utility Fleet Vehicles
The California Utilities entered into agreements in 2009 and 2010 to refinance existing fleet vehicles. These are capital leases and, at December 31, 2014, the related capital lease obligations were $2 million at Sempra Energy Consolidated, including $1 million at SDG&E and $1 million at SoCalGas. At December 31, 2013, the related capital lease obligations were $5 million at Sempra Energy Consolidated, including $3 million at SDG&E and $2 million at SoCalGas.
At December 31, 2014, the future minimum lease payments and present value of the net minimum lease payments under these capital leases are as follows:

Construction and Development Projects
Sempra Energy Consolidated has various capital projects in progress in the United States, Mexico and South America. Sempra Energy’s total commitments under these projects are $877 million, requiring future payments of $721 million in 2015, $93 million in 2016, $46 million in 2017, $10 million in 2018, $1 million in 2019 and $6 million thereafter. The following is a summary by segment of contractual commitments and contingencies related to the construction projects.
SDG&E
At December 31, 2014, SDG&E has commitments to make future payments of $340 million for construction projects that include
$130 million for the engineering, material procurement and construction costs primarily associated with the San Luis Rey Synchronous Condensor and Bay Boulevard Substation relocation projects;
$10 million related to nuclear fuel fabrication and other construction projects at SONGS; and
$200 million for infrastructure improvements for natural gas and electric transmission and distribution operations.
SDG&E expects future payments under these contractual commitments to be $229 million in 2015, $57 million in 2016, $37 million in 2017, $10 million in 2018, $1 million in 2019 and $6 million thereafter.
SoCalGas
At December 31, 2014, SoCalGas has commitments to make future payments of $260 million for construction and infrastructure improvements for natural gas storage, transmission and distribution operations and pipeline integrity. The future payments under these contractual commitments are expected to be $218 million in 2015, $33 million in 2016, and $9 million in 2017.
Sempra South American Utilities
At December 31, 2014, Sempra South American Utilities has commitments to make future payments of $15 million for construction projects that include $3 million for the construction of the Santa Teresa hydroelectric power plant at Luz del Sur. The future payments under these contractual commitments are all expected to be made in 2015.
Sempra Mexico
At December 31, 2014, Sempra Mexico has commitments to make future payments of $244 million for contracts related to the construction of an approximately 500-mile natural gas transport pipeline network. The future payments under these contractual commitments are expected to be $241 million in 2015 and $3 million in 2016.
Sempra Natural Gas
At December 31, 2014, Sempra Natural Gas has commitments to make future payments of $18 million primarily for natural gas transportation projects. The future payments under these contractual commitments are all expected to be made in 2015.
GUARANTEES
At December 31, 2014, SDG&E and SoCalGas did not have any outstanding guarantees.
At December 31, 2014, Sempra Renewables has provided guarantees to its solar and wind farm joint ventures aggregating a maximum of $170 million with an associated aggregated carrying value of $2 million, primarily related to purchased-power agreements and engineering, procurement and construction contracts. In addition, Sempra Renewables has provided guarantees aggregating a maximum of $332 million with an associated aggregated carrying value of $12 million at December 31, 2014 to certain wind farm joint ventures for debt service and operation of the wind farms, which we discuss in Note 5.
Sempra Energy entered into completion guarantees related to the financing of the Cameron LNG project, as we discuss in Note 4.
OTHER COMMITMENTS
SDG&E
In connection with the completion of the Sunrise Powerlink project in 2012, the CPUC required that SDG&E establish a fire mitigation fund to minimize the risk of fire as well as reduce the potential wildfire impact on residences and structures near the Sunrise Powerlink. The future payments for these contractual commitments are expected to be approximately $3 million per year, subject to escalation of 2 percent per year, for 58 years. At December 31, 2014, the present value of these future payments of $116 million has been recorded as a regulatory asset as the amounts represent a cost that will be recovered from customers in the future, and the related liability was $116 million.
In July 2012, SDG&E received $85 million from Citizens Sunrise Transmission, LLC (Citizens), a subsidiary of Citizens Energy Corporation. For this payment, under the terms of the agreement with Citizens, SDG&E will provide Citizens with access to a segment of the Sunrise Powerlink transmission line known as the Border-East transmission line equal to 50 percent of the transfer capacity of this portion of the line for a period of 30 years. After the 30-year contract term, the transfer capability will revert to SDG&E. SDG&E will amortize deferred revenues from the use of the transfer capability over the 30-year term, and depreciation for 50 percent of the Border-East transmission line segment will be accelerated from an estimated 58-year life to 30 years.
Sempra Natural Gas
In February 2013, Sempra Natural Gas entered into a long-term operations and maintenance agreement for its remaining block of the Mesquite Power natural gas-fired power plant, which expires in 2033. The total cost associated with this agreement is estimated to be approximately $33 million. The minimum future payments for this contractual commitment are expected to be $2 million each year in 2015 through 2019 and $23 million thereafter. We provide additional information about Mesquite Power in Note 3.
Additional consideration for a 2006 comprehensive legal settlement with the State of California to resolve the Continental Forge litigation included an agreement that, for a period of 18 years beginning in 2011, Sempra Natural Gas would sell to the California Utilities, subject to annual CPUC approval, up to 500 million cubic feet (MMcf) per day of regasified LNG from Sempra Mexico’s Energía Costa Azul facility that is not delivered or sold in Mexico at the California border index minus $0.02 per MMBtu. There are no specified minimums required, and to date, we have not been required to deliver any natural gas pursuant to this agreement.
ENVIRONMENTAL ISSUES
Our operations are subject to federal, state and local environmental laws. We also are subject to regulations related to hazardous wastes, air and water quality, land use, solid waste disposal and the protection of wildlife. These laws and regulations require that we investigate and correct the effects of the release or disposal of materials at sites associated with our past and our present operations. These sites include those at which we have been identified as a Potentially Responsible Party (PRP) under the federal Superfund laws and similar state laws.
In addition, we are required to obtain numerous governmental permits, licenses and other approvals to construct facilities and operate our businesses. The related costs of environmental monitoring, pollution control equipment, cleanup costs, and emissions fees are significant. Increasing national and international concerns regarding global warming and mercury, carbon dioxide, nitrogen oxide and sulfur dioxide emissions could result in requirements for additional pollution control equipment or significant emissions fees or taxes that could adversely affect Sempra Natural Gas and Sempra Mexico. The California Utilities’ costs to operate their facilities in compliance with these laws and regulations generally have been recovered in customer rates.
We generally capitalize the significant costs we incur to mitigate or prevent future environmental contamination or extend the life, increase the capacity, or improve the safety or efficiency of property used in current operations. The following table shows our capital expenditures (including construction work in progress) in order to comply with environmental laws and regulations:

Fluctuations at SDG&E and Sempra Energy Consolidated from 2012 to 2013 were primarily due to mitigation activities on the Sunrise Powerlink project, which was placed into service in June 2012. Fluctuations from 2013 to 2014 were primarily due to increased project activities during 2014, including PSEP-related projects at both SDG&E and SoCalGas and the Aliso Canyon turbine replacement project at SoCalGas. We have not identified any significant environmental issues outside the United States.
At the California Utilities, costs that relate to current operations or an existing condition caused by past operations are generally recorded as a regulatory asset due to the probability that these costs will be recovered in rates.
The environmental issues currently facing us or resolved during the last three years include (1) investigation and remediation of the California Utilities’ manufactured-gas sites, (2) cleanup of third-party waste-disposal sites used by the California Utilities at sites for which we have been identified as a PRP and (3) mitigation of damage to the marine environment caused by the cooling-water discharge from SONGS. The requirements for enhanced fish protection and restoration of 150 acres of coastal wetlands for the SONGS mitigation are in process and include a 150-acre artificial reef that was dedicated in 2008 and continues in process to meet California Coastal Commission (CCC) acceptance requirements. It is anticipated that the CCC will require expansion of the reef in 2015, as the existing reef may be too small to consistently meet the performance standard. The table below shows the status at December 31, 2014, of the California Utilities’ manufactured-gas sites and the third-party waste-disposal sites for which we have been identified as a PRP:

We record environmental liabilities at undiscounted amounts when our liability is probable and the costs can be reasonably estimated. In many cases, however, investigations are not yet at a stage where we can determine whether we are liable or, if the liability is probable, to reasonably estimate the amount or range of amounts of the costs. Estimates of our liability are further subject to uncertainties such as the nature and extent of site contamination, evolving cleanup standards and imprecise engineering evaluations. We review our accruals periodically and, as investigations and cleanup proceed, we make adjustments as necessary. The following table shows our accrued liabilities for environmental matters at December 31, 2014:

-1	Sites for which we have been identified as a Potentially Responsible Party.
-2	Does not include SDG&E’s liability for SONGS marine mitigation.
-3	This includes $7 million at SDG&E and $24 million at SoCalGas related to hazardous waste sites subject to the Hazardous Waste Collaborative mechanism approved by the CPUC in 1994. This mechanism permits California’s IOUs, including the California Utilities, to recover in rates 90 percent of hazardous waste cleanup costs and related third-party litigation costs, and 70 percent of the related insurance-litigation expenses for certain sites. In addition, the California Utilities have the opportunity to retain a percentage of any recoveries from insurance carriers and other third parties to offset the cleanup and associated litigation costs not recovered in rates.
We expect to pay the majority of these accruals over the next three years. In connection with the issuance of operating permits, SDG&E and the other owners of SONGS previously reached an agreement with the CCC to mitigate the damage to the marine environment caused by the cooling-water discharge from SONGS during its operation. SONGS’ early retirement, described in Note 13, does not reduce SDG&E’s mitigation obligation. At December 31, 2014, SDG&E’s share of the estimated mitigation costs remaining to be spent through 2050 is $20 million, which is recoverable in rates.
We discuss renewable energy requirements in Note 14 and greenhouse gas regulation in Note 1.
NUCLEAR INSURANCE
SDG&E and the other owners of SONGS have insurance to cover claims from nuclear liability incidents arising at SONGS. This insurance provides $375 million in coverage limits, the maximum amount available, including coverage for acts of terrorism. In addition, the Price-Anderson Act provides for up to $13.2 billion of secondary financial protection (SFP). If a nuclear liability loss occurring at any U.S. licensed/commercial reactor exceeds the $375 million insurance limit, all nuclear reactor owners could be required to contribute to the SFP. SDG&E’s contribution would be up to $50.93 million. This amount is subject to an annual maximum of $7.6 million, unless a default occurs by any other SONGS owner. If the SFP is insufficient to cover the liability loss, SDG&E could be subject to an additional assessment.
The SONGS owners, including SDG&E, also have $2.75 billion of nuclear property, decontamination, and debris removal insurance, subject to a $2.5 million deductible for “each and every loss.” This insurance coverage is provided through Nuclear Electric Insurance Limited (NEIL), a mutual insurance company. The NEIL policies have specific exclusions and limitations that can result in reduced or eliminated coverage. Insured members as a group are subject to retrospective premium assessments to cover losses sustained by NEIL under all issued policies. SDG&E could be assessed up to $9.7 million of retrospective premiums based on overall member claims. Edison, on behalf of itself and the minority owners of SONGS (including SDG&E), has placed NEIL on notice of claims under both the property damage and outage insurance policies as a result of SONGS’ Units 2 and 3 outages in early 2012 and the resultant plant closure in June 2013.
The nuclear property insurance program includes an industry aggregate loss limit for non-certified acts of terrorism (as defined by the Terrorism Risk Insurance Act). The industry aggregate loss limit for property claims arising from non-certified acts of terrorism is $3.24 billion. This is the maximum amount that will be paid to insured members who suffer losses or damages from these non-certified terrorist acts.
U.S. DEPARTMENT OF ENERGY (DOE) NUCLEAR FUEL DISPOSAL
The Nuclear Waste Policy Act of 1982 made the DOE responsible for the disposal of spent nuclear fuel. However, it is uncertain when the DOE will begin accepting spent nuclear fuel from SONGS. This delay will lead to increased costs for spent fuel storage. SDG&E will seek recovery for these costs from the appropriate sources, including, but not limited to, SDG&E’s Nuclear Decommissioning Trust. SDG&E will also continue to support Edison in its pursuit of legal claims on behalf of the SONGS co-owners against the DOE for its failure to timely accept the spent nuclear fuel.
In June 2010, the United States Court of Federal Claims issued a decision granting Edison and the SONGS co-owners damages of approximately $142 million to recover costs incurred through December 31, 2005 for the DOE’s failure to meet its obligation to begin accepting spent nuclear fuel from SONGS. Edison received payment from the federal government in the amount of the damage award in November 2011. In January 2012, Edison refunded SDG&E $28 million for its respective share of the damage award paid. SDG&E recorded a $10 million reduction of nuclear power expenses, a $15 million reduction of its nuclear decommissioning balancing account and a $3 million reduction in nuclear plant. Edison, as operating agent, filed a lawsuit against the DOE in the Court of Federal Claims in December 2011 seeking damages for the period from January 1, 2006 to December 31, 2010 for the DOE’s failure to meet its obligation to begin accepting spent nuclear fuel. In September 2014, Edison updated their claim to include another $84 million for costs incurred from January 2011 to December 2013.
CONCENTRATION OF CREDIT RISK
We maintain credit policies and systems to manage our overall credit risk. These policies include an evaluation of potential counterparties’ financial condition and an assignment of credit limits. These credit limits are established based on risk and return considerations under terms customarily available in the industry. We grant credit to utility customers and counterparties, substantially all of whom are located in our service territory, which covers most of Southern California and a portion of central California for SoCalGas, and all of San Diego County and an adjacent portion of Orange County for SDG&E. We also grant credit to utility customers and counterparties of our other companies providing natural gas or electric services in Mexico, Chile, Peru, southwest Alabama, and Hattiesburg, Mississippi.
When they become operational, projects owned or partially owned by Sempra Natural Gas, Sempra Renewables, Sempra South American Utilities and Sempra Mexico place significant reliance on the ability of their suppliers and customers to perform on long-term agreements and on our ability to enforce contract terms in the event of nonperformance. We consider many factors, including the negotiation of supplier and customer agreements, when we evaluate and approve development projects.

Notes to Consolidated Financial Statements [Abstract]
Segment Information	NOTE 16. SEGMENT INFORMATION
	We have six separately managed reportable segments, as follows:
	SDG&E provides electric service to San Diego and southern Orange counties and natural gas service to San Diego County.
	SoCalGas is a natural gas distribution utility, serving customers throughout most of Southern California and part of central California.
	Sempra South American Utilities operates electric transmission and distribution utilities in Chile and Peru.
	Sempra Mexico develops, owns and operates, or holds interests in, natural gas transmission pipelines and propane and ethane systems, a natural gas distribution utility, electric generation facilities (including wind), a terminal for the import of LNG, and marketing operations for the purchase of LNG and the purchase and sale of natural gas in Mexico.
	Sempra Renewables develops, owns and operates, or holds interests in, wind and solar energy projects in Arizona, California, Colorado, Hawaii, Indiana, Kansas, Nebraska, Nevada and Pennsylvania to serve wholesale electricity markets in the United States.
	Sempra Natural Gas develops, owns and operates, or holds interests in, natural gas pipelines and storage facilities, natural gas distribution utilities and a terminal for the import and export of LNG and sale of natural gas, all within the United States. Sempra Natural Gas also owns and operates the Mesquite Power plant, a natural gas-fired electric generation asset. In October 2014, Sempra Natural Gas entered into a definitive agreement to sell the remaining 625-MW block of Mesquite Power. The sale is expected to close in the first half of 2015, subject to obtaining third-party consents as we discuss in Note 3.
	Sempra South American Utilities and Sempra Mexico comprise our Sempra International operating unit. Sempra Renewables and Sempra Natural Gas comprise our Sempra U.S. Gas & Power operating unit.
	We evaluate each segment’s performance based on its contribution to Sempra Energy’s reported earnings. The California Utilities operate in essentially separate service territories, under separate regulatory frameworks and rate structures set by the CPUC. The California Utilities’ operations are based on rates set by the CPUC and the FERC. We describe the accounting policies of all of our segments in Note 1.
	Common services shared by the business segments are assigned directly or allocated based on various cost factors, depending on the nature of the service provided. Interest income and expense is recorded on intercompany loans. The loan balances and related interest are eliminated in consolidation.
	The following tables show selected information by segment from our Consolidated Statements of Operations and Consolidated Balance Sheets. We provide information about our equity method investments by segment in Note 4. Amounts labeled as “All other” in the following tables consist primarily of parent organizations.

	-1	Earnings per share are computed independently for each of the quarters and therefore may not sum to the total for the year.
	Revenues and Expenses and Other Income increased in each of the first three quarters in 2014 compared to 2013 partly due to higher natural gas prices, offset by lower volumes at SoCalGas. In the fourth quarter of 2014 compared to 2013, the impact on Revenues and Expenses and Other Income from lower volumes more than offset the impact from higher natural gas prices. In the first and fourth quarters of 2014 compared to 2013, the lower volumes were primarily due to a decrease in the demand for natural gas primarily from a warmer winter in 2014 compared to the same period in 2013.
	In each of the quarters of 2014 compared to the same periods in 2013, Revenues and Expenses and Other Income increased from higher cost of electric fuel and purchased power at SDG&E primarily due to the incremental purchase of renewable energy at higher prices.
	In the third quarter of 2014, Net Income and Earnings Attributable to Sempra Energy included $25 million tax benefit due to the release of a Louisiana valuation allowance against a deferred tax asset associated with Cameron LNG developments.
	Expenses and Other Income, Net Income and Earnings Attributable to Sempra Energy for the first, second and third quarters of 2014 included $9 million, $11 million and $14 million, respectively, of AFUDC related to equity associated with the construction of the Sonora natural gas pipeline in Mexico.
	In the first quarter of 2013, Expenses and Other Income were favorably impacted by $74 million and Net Income and Earnings Attributable to Sempra Energy were favorably impacted by $44 million due to the sale of one 625-MW block of the 1,250-MW Mesquite Power natural gas-fired power plant, as we discuss in Note 3.
	Net Income and Earnings Attributable to Sempra Energy for the first quarter of 2013 were negatively impacted by higher operating expenses at the California Utilities due to the delay in the CPUC decision on the 2012 GRC until the second quarter of 2013.
	Revenues and Expenses and Other Income for the third quarter of 2013 were lower compared to the first, second and fourth quarters of 2013 due to lower cost of natural gas.
	Net Income and Earnings Attributable to Sempra Energy for the first, second, third and fourth quarters of 2014 included $12 million, $12 million, $8 million and $6 million, respectively, of income tax expense for repatriation of current year foreign earnings. In the first quarter of 2013, Net Income and Earnings Attributable to Sempra Energy included $63 million income tax expense resulting from a corporate reorganization in connection with the IEnova stock offerings.
	In the second quarter of 2013, Revenues included $131 million and Net Income and Earnings Attributable to Sempra Energy included $106 million favorable impacts from the retroactive application of the 2012 GRC for the period from January 2012 to March 2013 at the California Utilities.
	In the second quarter of 2013, Expenses and Other Income were negatively impacted by $200 million and Net Income and Earnings Attributable to Sempra Energy were negatively impacted by $119 million due to the early retirement of SONGS, as we discuss in Note 13.
	We discuss quarterly fluctuations related to SDG&E and SoCalGas below.

In each of the quarters of 2014 compared to the same periods in 2013, SDG&E’s Operating Revenues and Operating Expenses included increases from higher cost of electric fuel and purchased power primarily due to the incremental purchase of renewable energy at higher prices.
Net Income and Earnings for the first quarter of 2013 were negatively impacted by higher operating expenses due to the delay in the CPUC decision on the 2012 GRC until the second quarter of 2013.
SDG&E’s Operating Revenues in the second quarter of 2013 included $90 million and Net Income and Earnings included $69 million favorable impacts from the retroactive application of the 2012 GRC for the period from January 2012 to March 2013.
In the second quarter of 2013, Operating Expenses were negatively impacted by $200 million and Net Income and Earnings were negatively impacted by $119 million due to the early retirement of SONGS, as we discuss in Note 13.

SoCalGas’ Operating Revenues and Operating Expenses increased in each of the first three quarters in 2014 compared to 2013 primarily due to higher natural gas prices, offset by lower volumes. In the fourth quarter of 2014 compared to 2013, the impact on Operating Revenues and Operating Expenses from lower volumes more than offset the impact from higher natural gas prices. In the first and fourth quarters of 2014 compared to 2013, the lower volumes were primarily due to a decrease in the demand for natural gas primarily from a warmer winter in 2014 compared to the same period in 2013.
Net Income and Earnings in the fourth quarter of 2014 compared to 2013 were impacted by lower income tax expenses in 2013 primarily related to resolution of prior years’ income tax items and higher flow-through deductions.
Net Income and Earnings in the first quarter of 2013 were negatively impacted by $12 million from higher operating expenses due to the delay in the CPUC decision on the 2012 GRC until the second quarter of 2013.
In the second quarter of 2013, Operating Revenues included $41 million and Net Income and Earnings included $37 million favorable impacts from the retroactive application of the 2012 GRC for the period from January 2012 to March 2013.

SIGNIFICANT_ACCOUNTING_POLICIE1

SIGNIFICANT ACCOUNTING POLICIES AND OTHER FINANCIAL DATA (Policies)	12 Months Ended
	Dec. 31, 2014
Allowance For Doubtfull Accounts [Abstract]
Trade And Other Accounts Receivable, Policy	COLLECTION ALLOWANCES
	We record allowances for the collection of trade and other accounts and notes receivable, which include allowances for doubtful customer accounts and for other receivables.
	We evaluate accounts receivable collectibility using a combination of factors, including past due status based on contractual terms, trends in write-offs, the age of the receivable, counterparty creditworthiness, economic conditions and specific events, such as bankruptcies. Adjustments to the allowance for doubtful accounts are made when necessary based on the results of analysis, the aging of receivables, and historical and industry trends.
	We write off accounts receivable in the period in which we deem the receivable to be uncollectible. We record recoveries of accounts receivable previously written off when it is known that they will be received.
Asset Retirement Obligations Policy [Abstract]
Asset Retirement Obligation Policy	ASSET RETIREMENT OBLIGATIONS
	For tangible long-lived assets, we record asset retirement obligations for the present value of liabilities of future costs expected to be incurred when assets are retired from service, if the retirement process is legally required and if a reasonable estimate of fair value can be made. We also record a liability if a legal obligation to perform an asset retirement exists and can be reasonably estimated, but performance is conditional upon a future event. We record the estimated retirement cost over the life of the related asset by depreciating the present value of the obligation (measured at the time of the asset’s acquisition) and accreting the discount until the liability is settled. Rate-regulated entities, including the California Utilities, record regulatory assets or liabilities as a result of the timing difference between the recognition of costs in accordance with U.S. GAAP and costs recovered through the rate-making process.
Cash And Cash Equivalents Policy [Abstract]
Cash and Cash Equivalents, Policy	CASH AND CASH EQUIVALENTS
	Cash equivalents are highly liquid investments with maturities of three months or less at the date of purchase.
Commitments And Contingencies Policy [Abstract]
Contingencies, Policy	CONTINGENCIES
	We accrue losses for the estimated impacts of various conditions, situations or circumstances involving uncertain outcomes. For loss contingencies, we accrue the loss if an event has occurred on or before the balance sheet date and:
	information available through the date we file our financial statements indicates it is probable that a loss has been incurred, given the likelihood of uncertain future events; and
	the amount of the loss can be reasonably estimated.
	We do not accrue contingencies that might result in gains. We continuously assess contingencies for litigation claims, environmental remediation and other events.
Consolidation Policy [Abstract]
Principles of Consolidation	Sempra Energy uses the equity method to account for investments in affiliated companies over which we have the ability to exercise significant influence, but not control.
	VARIABLE INTEREST ENTITIES (VIE)
	We consolidate a VIE if we are the primary beneficiary of the VIE. Our determination of whether we are the primary beneficiary is based upon qualitative and quantitative analyses, which assess
	the purpose and design of the VIE;
	the nature of the VIE’s risks and the risks we absorb;
	the power to direct activities that most significantly impact the economic performance of the VIE; and
	the obligation to absorb losses or right to receive benefits that could be significant to the VIE.
	Sempra Energy’s other operating units also enter into arrangements which could include variable interests. We evaluate these arrangements and applicable entities based upon the qualitative and quantitative analyses described above. Certain of these entities are service companies that are VIEs. As the primary beneficiary of these service companies, we consolidate them. In all other cases, we have determined that these contracts are not variable interests in a VIE and therefore are not subject to the U.S. GAAP requirements concerning the consolidation of VIEs.
Cost Of Sales Policy [Abstract]
Other Cost of Sales, Policy	OTHER COST OF SALES
	Other Cost of Sales primarily includes
	pipeline capacity costs, and pipeline transportation and natural gas marketing costs incurred at Sempra Natural Gas;
	electric construction services costs incurred by Sempra South American Utilities’ energy-services companies; and
	energy management service fees at Sempra Mexico
Emission Credits Policy [Abstract]
Emission Credits or Allowances Policy	GREENHOUSE GAS ALLOWANCES
	The California Utilities, Sempra Mexico and Sempra Natural Gas are required by California Assembly Bill 32 to acquire greenhouse gas allowances for every metric ton of carbon dioxide equivalent emitted into the atmosphere during electric generation and natural gas transportation. We record greenhouse gas allowances at the lower of weighted average cost or market, and include them in Other Current Assets and Sundry on the Consolidated Balance Sheets based on the dates that they are required to be surrendered. We measure the compliance obligation, which is based on emissions, at the carrying value of allowances held plus the fair value of additional allowances necessary to satisfy the obligation. We include the obligation in Other Current Liabilities and Deferred Credits on the Consolidated Balance Sheets based on the dates that the allowances will be surrendered. We remove the assets and liabilities from the balance sheets as the allowances are surrendered.
	The California Utilities expect that costs and revenues associated with the greenhouse gas program will be recorded through Regulatory Balancing Accounts on the Consolidated Balance Sheets.
	RENEWABLE ENERGY CERTIFICATES
	Renewable energy certificates (RECs) represent property rights established by governmental agencies for the environmental, social, and other nonpower qualities of renewable electricity generation. A REC, and its associated attributes and benefits, can be sold separately from the underlying physical electricity associated with a renewable-based generation source in certain markets.
	Retail sellers of electricity obtain RECs through renewable power purchase agreements, internal generation or separate purchases in the market to comply with renewable portfolio standards established by the governmental agencies. RECs are the mechanism used to verify renewable portfolio standards compliance. The cost of RECs is recorded in Cost of Electric Fuel and Purchased Power, which is recoverable in rates, on the Consolidated Statements of Operations.
Fair Value Measurements Policy [Abstract]
Fair Value Measurements, Policy	FAIR VALUE MEASUREMENTS
	We apply recurring fair value measurements to certain assets and liabilities, primarily nuclear decommissioning and benefit plan trust assets and other miscellaneous derivatives. “Fair value” is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).
	A fair value measurement reflects the assumptions market participants would use in pricing an asset or liability based on the best available information. These assumptions include the risk inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. Also, we consider an issuer’s credit standing when measuring its liabilities at fair value.
	We establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows:
	Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Our Level 1 financial instruments primarily consist of listed equities, U.S. government treasury securities and exchange-traded derivatives.
	Level 2 – Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including:
	quoted forward prices for commodities
	time value
	current market and contractual prices for the underlying instruments
	volatility factors
	other relevant economic measures
	Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Our financial instruments in this category include domestic corporate bonds, municipal bonds and other foreign bonds, primarily in the Nuclear Decommissioning Trusts and in our pension and postretirement benefit plans, and non-exchange-traded derivatives such as interest rate instruments and over-the-counter (OTC) forwards and options.
	Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value from the perspective of a market participant.
Foreign Currency Transactions And Translations Policy [Abstract]
Foreign Currency Translation, Policy	FOREIGN CURRENCY TRANSLATION
	Our operations in South America and our natural gas distribution utility in Mexico use their local currency as their functional currency. The assets and liabilities of their foreign operations are translated into U.S. dollars at current exchange rates at the end of the reporting period, and revenues and expenses are translated at average exchange rates for the year. The resulting noncash translation adjustments do not enter into the calculation of earnings or retained earnings (unless the operation is being discontinued), but are reflected in Comprehensive Income and in Accumulated Other Comprehensive Income (Loss), a component of shareholders’ equity.
Goodwill And Intangible Assets, Policy [Abstract]
Goodwill and Intangible Assets, Policy	GOODWILL AND OTHER INTANGIBLE ASSETS
	Goodwill
	Goodwill is the excess of the purchase price over the fair value of the identifiable net assets of acquired companies measured at the time of acquisition. Goodwill is not amortized but is tested for impairment annually on October 1 or whenever events or changes in circumstances necessitate an evaluation. Impairment of goodwill occurs when the carrying amount (book value) of goodwill exceeds its implied fair value. If the carrying value of the reporting unit, including goodwill, exceeds its fair value, and the book value of goodwill is greater than its fair value on the test date, we record a goodwill impairment loss.
	For our annual goodwill impairment testing, under current U.S. GAAP guidance we have the option to first make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount before applying the two-step, quantitative goodwill impairment test. If we elect to perform the qualitative assessment, we evaluate relevant events and circumstances, including but not limited to, macroeconomic conditions, industry and market considerations, cost factors, changes in key personnel and the overall financial performance of the reporting unit. If, after assessing these qualitative factors, we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform the two-step goodwill impairment test. When we perform the two-step, quantitative goodwill impairment test, we exercise judgment to develop estimates of the fair value of the reporting unit and the corresponding goodwill. Our fair value estimates are developed from the perspective of a knowledgeable market participant. We consider observable transactions in the marketplace for similar investments, if available, as well as an income-based approach such as discounted cash flow analysis. A discounted cash flow analysis may be based directly on anticipated future revenues and expenses and may be performed based on free cash flows generated within the reporting unit. Critical assumptions that affect our estimates of fair value may include
	consideration of market transactions
	future cash flows
	the appropriate risk-adjusted discount rate
	country risk
	entity risk
	Other Intangible Assets
	Other Intangible Assets primarily represent storage and development rights related to the natural gas storage facilities of Bay Gas Storage Company, Ltd. (Bay Gas) and Mississippi Hub, LLC (Mississippi Hub), which are being amortized over their estimated useful lives as shown in the table below.
Impairment Or Disposal Of Long Lived Assets Policy [Abstract]
Impairment or Disposal of Long-lived Assets, Policy	LONG-LIVED ASSETS
	We test long-lived assets for recoverability whenever events or changes in circumstances have occurred that may affect the recoverability or the estimated useful lives of long-lived assets. Long-lived assets include intangible assets subject to amortization, but do not include investments in unconsolidated subsidiaries. Events or changes in circumstances that indicate that the carrying amount of a long-lived asset may not be recoverable may include
	significant decreases in the market price of an asset
	a significant adverse change in the extent or manner in which we use an asset or in its physical condition
	a significant adverse change in legal or regulatory factors or in the business climate that could affect the value of an asset
	a current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection of continuing losses associated with the use of a long-lived asset
	a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life
	Impairment of long-lived assets occurs when the estimated future undiscounted cash flows are less than the carrying amount of the assets. If that comparison indicates that the assets’ carrying value may not be recoverable, the impairment is measured based on the difference between the carrying amount and the fair value of the assets. This evaluation is performed at the lowest level for which separately identifiable cash flows exist.
Income Tax Policy [Abstract]
Income Taxes, Policy	INCOME TAXES
	Income tax expense includes current and deferred income taxes from operations during the year. We record deferred income taxes for temporary differences between the book and the tax basis of assets and liabilities. Investment tax credits from prior years are amortized to income by the California Utilities over the estimated service lives of the properties as required by the CPUC. At our other businesses, we reduce the book basis of the related asset by the amount of investment tax credit earned. At Sempra Renewables, production tax credits are recognized in income tax expense as earned.
	The California Utilities, Mobile Gas and Willmut Gas recognize
	regulatory assets to offset deferred tax liabilities if it is probable that the amounts will be recovered from customers; and
	regulatory liabilities to offset deferred tax assets if it is probable that the amounts will be returned to customers.
	We currently do not record deferred income taxes for basis differences between financial statement and income tax investment amounts in non-U.S. subsidiaries and non-U.S. joint ventures because their cumulative undistributed earnings are indefinitely reinvested.
	When there are uncertainties related to potential income tax benefits, in order to qualify for recognition, the position we take has to have at least a “more likely than not” chance of being sustained (based on the position’s technical merits) upon challenge by the respective authorities. The term “more likely than not” means a likelihood of more than 50 percent. Otherwise, we may not recognize any of the potential tax benefit associated with the position. We recognize a benefit for a tax position that meets the “more likely than not” criterion at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon its effective resolution.
	Unrecognized tax benefits involve management’s judgment regarding the likelihood of the benefit being sustained. The final resolution of uncertain tax positions could result in adjustments to recorded amounts and may affect our results of operations, financial position and cash flows.
	For SDG&E and SoCalGas, the CPUC requires flow-through rate-making treatment for the current income tax benefit or expense arising from certain property-related and other temporary differences between the treatment for financial reporting and income tax, which will reverse over time. Under the regulatory accounting treatment required for these flow-through temporary differences, deferred income tax assets and liabilities are not recorded to deferred income tax expense, but rather to a regulatory asset or liability, which results in impacting the current effective income tax rate. As a result, changes in the relative size of these items compared to pretax income, from period to period, can cause variations in the effective income tax rate. The following items are subject to flow-through treatment:
	repairs expenditures related to a certain portion of utility plant fixed assets
	the equity portion of AFUDC
	a portion of the cost of removal of utility plant assets
	self-developed software expenditures
	depreciation on a certain portion of utility plant assets
	The AFUDC related to equity recorded for regulated construction projects at Sempra Mexico and Sempra Natural Gas has similar flow-through treatment.
	We use the deferral method for investment tax credits (ITC). For certain solar and wind generating assets placed into service during 2012, we elected to seek cash grants rather than ITC for which the projects also qualify. Accordingly, cash grant accounting was applied. Grant accounting for cash grants is very similar to the deferral method of accounting for ITC, the primary difference being the recording of a cash grant receivable instead of an income tax receivable.
	Under the deferral method of accounting for ITC and under grant accounting for cash grants, we record a deferred income tax benefit, on day one, which is reflected in income tax expense by recording a deferred income tax asset during the year the renewable energy assets are placed in service. This deferred income tax asset results from the day-one difference in the income tax basis and financial statement basis of the renewable energy assets, referred to as the day-one basis difference. The financial statement basis of the assets is reduced by 100 percent of the ITC or grant expected; U.S. federal income tax basis is reduced by only 50 percent for both ITC and grants; and state income tax basis is reduced by 50 percent for grants and not at all for ITC.
	Conversion of ITC to cash is generally dependent on reducing income tax payments and thus the existence of a U.S. federal net operating loss (NOL) carryforward can result in delaying this conversion.
Inventory Policy [Abstract]
Inventories, Policy	INVENTORIES
	The California Utilities value natural gas inventory by the last-in first-out (LIFO) method. As inventories are sold, differences between the LIFO valuation and the estimated replacement cost are reflected in customer rates. Materials and supplies at the California Utilities are generally valued at the lower of average cost or market.
	Sempra South American Utilities, Sempra Mexico and Sempra Natural Gas value natural gas inventory and materials and supplies at the lower of average cost or market. Sempra Mexico and Sempra Natural Gas value liquefied natural gas (LNG) inventory by the first-in first-out method.
Legal Costs Policy [Abstract]
Legal Fees, Policy	LEGAL FEES
	Legal fees that are associated with a past event for which a liability has been recorded are accrued when it is probable that fees also will be incurred.
	LEGAL PROCEEDINGS
	We accrue losses for a legal proceeding when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. However, the uncertainties inherent in legal proceedings make it difficult to estimate with reasonable certainty the costs and effects of resolving these matters. Accordingly, actual costs incurred may differ materially from amounts accrued, may exceed applicable insurance coverage and could materially adversely affect our business, cash flows, results of operations, financial condition and prospects. Unless otherwise indicated, we are unable to estimate reasonably possible losses in excess of any amounts accrued.
Noncontrolling Interest Policy [Abstract]
Noncontrolling Interest Policy [Text Block]	NONCONTROLLING INTERESTS
	Ownership interests that are held by owners other than Sempra Energy and SDG&E in subsidiaries or entities consolidated by them are accounted for and reported as noncontrolling interests. As a result, noncontrolling interests are reported as a separate component of equity on the Consolidated Balance Sheets. Earnings/losses attributable to the noncontrolling interests are separately identified on the Consolidated Statements of Operations, and net income/loss and comprehensive income/loss attributable to the noncontrolling interests are separately identified on the Consolidated Statements of Comprehensive Income and Consolidated Statements of Changes in Equity.
Property Plant And Equipment Policy [Abstract]
Property, Plant and Equipment, Policy	PROPERTY, PLANT AND EQUIPMENT
	Property, plant and equipment primarily represents the buildings, equipment and other facilities used by the California Utilities to provide natural gas and electric utility services, and by Sempra International and Sempra U.S. Gas & Power, including construction work in progress at these operating units. Property, plant and equipment also includes lease improvements and other equipment at Parent, as well as property acquired under a build-to-suit lease included in construction work in progress.
	Our plant costs include
	labor
	materials and contract services
	expenditures for replacement parts incurred during a major maintenance outage of a generating plant
	In addition, the cost of our utility plant and selected non-utility regulated projects at Sempra Mexico and Sempra Natural Gas includes an allowance for funds used during construction (AFUDC). We discuss AFUDC below. The cost of non-utility plant includes capitalized interest.
	Maintenance costs are expensed as incurred. The cost of most retired depreciable utility plant minus salvage value is charged to accumulated depreciation.
	Depreciation expense is based on the straight-line method over the useful lives of the assets or, for the California Utilities, a shorter period prescribed by the CPUC. Depreciation expense is computed using the straight-line method over the asset’s estimated original composite useful life, the CPUC-prescribed period or the remaining term of the site leases, whichever is shortest.
	The California Utilities finance their construction projects with borrowed funds and equity funds. The CPUC and the FERC allow the recovery of the cost of these funds by the capitalization of AFUDC, calculated using rates authorized by the CPUC and the FERC, as a cost component of property, plant and equipment. The California Utilities earn a return on the capitalized AFUDC after the utility property is placed in service and recover the AFUDC from their customers over the expected useful lives of the assets.
	Pipeline projects currently under construction by Sempra Mexico and Sempra Natural Gas that are both subject to certain regulation and meet U.S. GAAP regulatory accounting requirements record the impact of AFUDC related to equity.
	Sempra International and Sempra U.S. Gas & Power businesses capitalize interest costs incurred to finance capital projects and interest on equity method investments that have not commenced planned principal operations. The California Utilities also capitalize certain interest costs.
Public Utilities Policy [Abstract]
Regulatory Matters, Policy	REGULATORY MATTERS
	Effects of Regulation
	The accounting policies of our regulated utility subsidiaries in California, SDG&E and SoCalGas, conform with U.S. GAAP for regulated enterprises and reflect the policies of the California Public Utilities Commission (CPUC) and the Federal Energy Regulatory Commission (FERC).
	The California Utilities prepare their financial statements in accordance with U.S. GAAP provisions governing regulated operations. Under these provisions, a regulated utility records regulatory assets, which are generally costs that would otherwise be charged to expense, if it is probable that, through the ratemaking process, the utility will recover those assets from customers. To the extent that recovery is no longer probable, the related regulatory assets are written off. Regulatory liabilities generally represent amounts collected from customers in advance of the actual expenditure by the utility. If the actual expenditures are less than amounts previously collected from ratepayers, the excess would be refunded to customers, generally by reducing future rates. Regulatory liabilities may also arise from other transactions such as unrealized gains on fixed price contracts and other derivatives or certain deferred income tax benefits that are passed through to customers in future rates. In addition, the California Utilities record regulatory liabilities when the CPUC or the FERC requires a refund to be made to customers or has required that a gain or other transaction of net allowable costs be given to customers over future periods.
	Determining probability of recovery requires significant judgment by management and may include, but is not limited to, consideration of:
	the nature of the event giving rise to the assessment;
	existing statutes and regulatory code;
	legal precedents;
	regulatory principles and analogous regulatory actions;
	testimony presented in regulatory hearings;
	proposed regulatory decisions;
	final regulatory orders;
	a commission-authorized mechanism established for the accumulation of costs;
	status of applications for rehearings or state court appeals;
	specific approval from a commission; and
	historical experience.
	Our other natural gas distribution utilities, Mobile Gas, Willmut Gas and Ecogas, also apply U.S. GAAP for regulated utilities to their operations.
	Regulatory Balancing Accounts
	Over- and undercollected regulatory balancing accounts reflect the difference between customer billings and recorded or CPUC-authorized costs, primarily commodity costs. Amounts in the balancing accounts are recoverable (receivable) or refundable (payable) in future rates, subject to CPUC approval. Balancing account treatment eliminates the impact on earnings from variances in the covered costs from authorized amounts. Absent balancing account treatment, variations in the cost of fuel supply and certain operating and maintenance costs from amounts approved by the CPUC would increase volatility in utility earnings.
	Incentive awards are included in our earnings when we receive any required CPUC approval of the award. We would record penalties for results below the specified benchmarks in earnings when we believe it is more likely than not that the CPUC would assess a penalty.
Revenue Recognition Policy [Abstract]
Revenues, Policy	REVENUES
	Utilities
	Our California Utilities generate revenues primarily from deliveries to their customers of electricity by SDG&E and natural gas by both SoCalGas and SDG&E and from related services. They record these revenues following the accrual method and recognize them upon delivery and performance. They also record revenue from CPUC-approved incentive awards, some of which require approval by the CPUC prior to being recognized.
	On a monthly basis, SoCalGas accrues natural gas storage contract revenues, which consist of storage reservation and variable charges based on negotiated agreements with terms of up to 15 years.
	Our natural gas utilities outside of California (Mobile Gas, Willmut Gas and Ecogas) apply U.S. GAAP for regulated utilities consistent with the California Utilities.
	Our electric distribution utilities in South America, Chilquinta Energía and Luz del Sur, serve primarily regulated customers, and their revenues are based on tariffs that are set by the National Energy Commission (Comisión Nacional de Energía, or CNE) in Chile and the Energy and Mining Investment Supervisory Body (Organismo Supervisor de la Inversión en Energía y Minería, or OSINERGMIN) of the National Electricity Office under the Ministry of Energy and Mines in Peru.
	The tariffs charged are based on an efficient model distribution company defined by Chilean law in the case of Chilquinta Energía, and OSINERGMIN in the case of Luz del Sur. The tariffs include operation and maintenance costs, an internal rate of return on the new replacement value of depreciable assets, charges for the use of transmission systems, and a component for the value added by the distributor. Tariffs are designed to provide for a pass-through to customers of the main noncontrollable cost items (mainly power purchases and transmission charges), recovery of reasonable operating and administrative costs, incentives to reduce costs and make needed capital investments and a regulated rate of return on the distributor’s regulated asset base. Because the tariffs are based on a model and are intended to cover the costs of the model company, but are not based on the costs of the specific utility and may not result in full cost recovery, they do not meet the requirement necessary for treatment under applicable U.S. GAAP for regulatory accounting.
	As we discuss in Note 14, the natural gas supply for SDG&E’s and SoCalGas’ core natural gas customers is purchased by SoCalGas as a combined procurement portfolio managed by SoCalGas. Core customers are primarily residential and small commercial and industrial customers. This core gas procurement function is considered a shared service, therefore amounts related to SDG&E are not included in SoCalGas’ Consolidated Statements of Operations.
	Energy-Related Businesses
	Sempra South American Utilities
	Sempra South American Utilities generates revenues from energy-services companies that provide electric construction services and recognizes these revenues when services are provided in accordance with contractual agreements. The energy-services company in Chile also generates revenue from selling electricity to non-regulated customers.
	Sempra Mexico
	Sempra Mexico’s Termoeléctrica de Mexicali natural gas-fired power plant generates revenues from selling electricity and/or capacity to the California Independent System Operator (ISO) and to governmental, public utility and wholesale power marketing entities. Sempra Mexico recognizes these revenues as the electricity is delivered and capacity is provided. Sempra Mexico’s pipeline operations recognize revenues from the sale and transportation of natural gas as deliveries are made and from fixed capacity payments. Sempra Mexico also recognizes revenues from (1) the sale of LNG and natural gas as deliveries are made to counterparties and (2) from reservation and usage fees under terminal capacity agreements, nitrogen injection service agreements and tug service agreements. It reports revenue net of value added taxes in Mexico. Sempra Mexico’s revenues also include net realized gains and losses and the net change in the fair value of unrealized gains and losses on derivative contracts for natural gas.
	Sempra Renewables
	For consolidated entities, Sempra Renewables generates revenues from the sale of solar power pursuant to power purchase agreements, and recognizes these revenues when the power is delivered. It also generates revenues for the management of certain of its solar and wind project joint ventures.
	Sempra Natural Gas
	Sempra Natural Gas generates revenues from selling electricity and/or capacity from its Mesquite Power facility to the California ISO and to governmental, public utility and wholesale power marketing entities. Sempra Natural Gas recognizes these revenues as the electricity is delivered and capacity is provided. Related to its LNG terminal, prior to October 1, 2014, the effective date of the Cameron LNG Holdings joint venture, Sempra Natural Gas recognized revenues from reservation and usage fees. We discuss the deconsolidation of Cameron LNG, LLC and related assets further in Note 3. Sempra Natural Gas also records revenues from contractual counterparty obligations for non-delivery of LNG cargoes, as well as revenues from the sale of LNG and natural gas as deliveries are made to counterparties. Sempra Natural Gas recognizes revenue on natural gas storage and transportation operations when services are provided in accordance with contractual agreements for the storage and transportation services. Sempra Natural Gas revenues also include net realized gains and losses and the net change in the fair value of unrealized gains and losses on derivative contracts for power and natural gas.

Pension and other postretirement benefit
Pension And Other Postretirement Plans Policy	NOTE 7. EMPLOYEE BENEFIT PLANS
	We are required by applicable U.S. GAAP to:
	recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status in the statement of financial position;
	measure a plan’s assets and its obligations that determine its funded status as of the end of the fiscal year (with limited exceptions); and
	recognize changes in the funded status of pension and other postretirement benefit plans in the year in which the changes occur. Generally, those changes are reported in other comprehensive income and as a separate component of shareholders’ equity.
	The detailed information presented below covers the employee benefit plans of Sempra Energy and its principal subsidiaries.
	Sempra Energy has funded and unfunded noncontributory traditional defined benefit and cash balance plans, including separate plans for SDG&E and SoCalGas, which collectively cover all eligible employees, including members of the Sempra Energy board of directors who were participants in a predecessor plan on or before June 1, 1998. Pension benefits under the traditional defined benefit plans are based on service and final average pay, while the cash balance plans provide benefits using a career average earnings methodology.
	Chilquinta Energía has an unfunded contributory defined benefit plan covering all employees hired before October 1, 1981 and an unfunded noncontributory termination indemnity obligation covering all employees. The plans generally provide defined benefits to retirees based on date of hire, years of service and final average salary.
	Sempra Energy also has other postretirement benefit plans (PBOP), including separate plans for SDG&E and SoCalGas, which collectively cover all domestic (except Willmut Gas) and certain foreign employees. The life insurance plans are both contributory and noncontributory, and the health care plans are contributory. Participants’ contributions are adjusted annually. Other postretirement benefits include medical benefits for retirees’ spouses.
	Chilquinta Energía also has two noncontributory postretirement benefit plans which cover substantially all employees – a health care plan and an energy subsidy plan that provides for reduced energy rates. The health care plan includes benefits for retirees’ spouses and dependents.
	Pension and other postretirement benefits costs and obligations are dependent on assumptions used in calculating such amounts. These assumptions include
	discount rates
	expected return on plan assets
	health care cost trend rates
	mortality rates
	rate of compensation increases
	termination and retirement rates
	utilization of postretirement welfare benefits
	payout elections (lump sum or annuity)
	lump sum interest rates
	We review these assumptions on an annual basis prior to the beginning of each year and update them as appropriate. We consider current market conditions, including interest rates, in making these assumptions. New mortality table studies were released by the Society of Actuaries during 2014 that significantly increased life expectancy assumptions, and we have incorporated these new assumptions, adjusted for the Sempra Energy companies’ actual mortality experience, in our calculations. We use a December 31 measurement date for all of our plans.
	Net Assets and Liabilities
	The assets and liabilities of the pension and other postretirement benefit plans are affected by changing market conditions as well as when actual plan experience is different than assumed. Such events result in investment gains and losses, which we defer and recognize in pension and other postretirement benefit costs over a period of years. Sempra Energy Consolidated (except for SDG&E) and SoCalGas use the asset smoothing method for their pension and other postretirement plans. This method develops an asset value that recognizes realized and unrealized investment gains and losses over a three-year period. This adjusted asset value, known as the market-related value of assets, is used in conjunction with an expected long-term rate of return to determine the expected return-on-assets component of net periodic cost. SDG&E does not use the asset smoothing method, but rather recognizes realized and unrealized investment gains and losses during the current year.
	The 10-percent corridor accounting method is used at Sempra Energy Consolidated, SDG&E and SoCalGas. Under the corridor accounting method, if as of the beginning of a year unrecognized net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the market-related value of plan assets, the excess is amortized over the average remaining service period of active participants. The asset smoothing and 10-percent corridor accounting methods help mitigate volatility of net periodic costs from year to year.
	We recognize the overfunded or underfunded status of defined benefit pension and other postretirement plans as assets or liabilities, respectively; unrecognized changes in these assets and/or liabilities are normally recorded in Accumulated Other Comprehensive Income (Loss) on the balance sheet. The California Utilities and Mobile Gas record regulatory assets and liabilities that offset the funded pension and other postretirement plans’ assets or liabilities, as these costs are expected to be recovered in future utility rates based on agreements with regulatory agencies. At Willmut Gas, pension contributions are recovered in rates on a prospective basis, but are not recorded as a regulatory asset pending recovery.
	The California Utilities record annual pension and other postretirement net periodic benefit costs equal to the contributions to their plans as authorized by the CPUC. The annual contributions to the pension plans are limited to a minimum required funding amount as determined by the Internal Revenue Service. The annual contributions to the other postretirement plans are equal to the lesser of the maximum tax deductible amount or the net periodic cost calculated in accordance with U.S. GAAP for pension and other postretirement benefit plans. Mobile Gas records annual pension and other postretirement net periodic benefit costs based on an estimate of the net periodic cost at the beginning of the year calculated in accordance with U.S. GAAP for pension and other postretirement benefit plans, as authorized by the Alabama Public Service Commission. Any differences between booked net periodic benefit cost and amounts contributed to the pension and other postretirement plans for the California Utilities are disclosed as regulatory adjustments in accordance with U.S. GAAP for regulated entities.

Share-based compensation
Share-Based Compensation Policy	SHARE-BASED AWARDS AND COMPENSATION EXPENSE
	We measure and recognize compensation expense for all share-based payment awards made to our employees and directors based on estimated fair values on the date of grant. We recognize compensation costs net of an estimated forfeiture rate (based on historical experience) and recognize the compensation costs for non-qualified stock options and restricted stock and stock units on a straight-line basis over the requisite service period of the award, which is generally four years. However, in the year that an employee becomes eligible for retirement, the remaining expense related to the employee’s awards is recognized immediately. Substantially all awards outstanding are classified as equity instruments; therefore, we recognize additional paid in capital as we recognize the compensation expense associated with the awards.
	We classify the tax benefits resulting from tax deductions in excess of the tax benefit related to compensation cost recognized for stock option exercises as financing cash flows.
	We use a Black-Scholes option-pricing model (Black-Scholes model) to estimate the fair value of each non-qualified stock option grant. The use of a valuation model requires us to make certain assumptions about selected model inputs. Expected volatility is calculated based on the historical volatility of Sempra Energy’s stock price. We base the average expected life for options on the contractual term of the option and expected employee exercise and post-termination behavior.
	SEMPRA ENERGY RESTRICTED STOCK AWARDS AND UNITS
	We use a Monte-Carlo simulation model to estimate the fair value of the restricted stock awards and units. Our determination of fair value is affected by the volatility of the stock price and the dividend yields for Sempra Energy and its peer group companies. The valuation also is affected by the risk-free rates of return, and a number of other variables.

DERIVATIVE_FINANCIAL_INSTRUMEN1

DERIVATIVE FINANCIAL INSTRUMENTS (Policies)	12 Months Ended
	Dec. 31, 2014
Derivatives Policy [Abstract]
Derivatives, Policy [Text Block]	We use derivative instruments primarily to manage exposures arising in the normal course of business. Our principal exposures are commodity market risk and benchmark interest rate risk. We may also manage foreign exchange rate exposures using derivatives. Our use of derivatives for these risks is integrated into the economic management of our anticipated revenues, anticipated expenses, assets and liabilities. Derivatives may be effective in mitigating these risks (1) that could lead to declines in anticipated revenues or increases in anticipated expenses, or (2) that our asset values may fall or our liabilities increase. Accordingly, our derivative activity summarized below generally represents an impact that is intended to offset associated revenues, expenses, assets or liabilities that are not presented below.
	We record all derivatives at fair value on the Consolidated Balance Sheets. We designate each derivative as (1) a cash flow hedge, (2) a fair value hedge, or (3) undesignated. Depending on the applicability of hedge accounting and, for the California Utilities and other operations subject to regulatory accounting, the requirement to pass impacts through to customers, the impact of derivative instruments may be offset in other comprehensive income (cash flow hedge), on the balance sheet (fair value hedges and regulatory offsets), or recognized in earnings. We classify cash flows from the settlements of derivative instruments as operating activities on the Consolidated Statements of Cash Flows.
	In certain cases, we apply the normal purchase or sale exception to derivative accounting and have other commodity contracts that are not derivatives. These contracts are not recorded at fair value and are therefore excluded from the disclosures below.
	HEDGE ACCOUNTING
	We may designate a derivative as a cash flow hedging instrument if it effectively converts anticipated revenues or expenses to a fixed dollar amount. We may utilize cash flow hedge accounting for derivative commodity instruments, foreign currency instruments and interest rate instruments. Designating cash flow hedges is dependent on the business context in which the instrument is being used, the effectiveness of the instrument in offsetting the risk that a given future revenue or expense item may vary, and other criteria.
	We may designate an interest rate derivative as a fair value hedging instrument if it effectively converts our own debt from a fixed interest rate to a variable rate. The combination of the derivative and debt instrument results in fixing that portion of the fair value of the debt that is related to benchmark interest rates. Designating fair value hedges is dependent on the instrument being used, the effectiveness of the instrument in offsetting changes in the fair value of our debt instruments, and other criteria.
	ENERGY DERIVATIVES
	Our market risk is primarily related to natural gas and electricity price volatility and the specific physical locations where we transact. We use energy derivatives to manage these risks. The use of energy derivatives in our various businesses depends on the particular energy market, and the operating and regulatory environments applicable to the business.
	The California Utilities use natural gas energy derivatives, for the benefit of customers, with the objective of managing price risk and basis risks, and lowering natural gas costs. These derivatives include fixed price natural gas positions, options, and basis risk instruments, which are either exchange-traded or over-the-counter financial instruments. This activity is governed by risk management and transacting activity plans that have been filed with and approved by the CPUC. Natural gas derivative activities are recorded as commodity costs that are offset by regulatory account balances and are recovered in rates. Net commodity cost impacts on the Consolidated Statements of Operations are reflected in Cost of Electric Fuel and Purchased Power or in Cost of Natural Gas.
	SDG&E is allocated and may purchase congestion revenue rights (CRRs), which serve to reduce the regional electricity price volatility risk that may result from local transmission capacity constraints. Unrealized gains and losses do not impact earnings, as they are offset by regulatory account balances. Realized gains and losses associated with CRRs are recorded in Cost of Electric Fuel and Purchased Power, which is recoverable in rates, on the Consolidated Statements of Operations.
	Sempra Mexico and Sempra Natural Gas may use natural gas and electricity derivatives, as appropriate, to optimize the earnings of their assets which support the following businesses: LNG, natural gas transportation, power generation, and Sempra Natural Gas’ storage. Gains and losses associated with undesignated derivatives are recognized in Energy-Related Businesses Revenues or in Cost of Natural Gas, Electric Fuel and Purchased Power on the Consolidated Statements of Operations. Certain of these derivatives may also be designated as cash flow hedges. Sempra Mexico also uses natural gas energy derivatives with the objective of managing price risk and lowering natural gas prices at its Mexican distribution operations. These derivatives, which are recorded as commodity costs that are offset by regulatory account balances and recovered in rates, are recognized in Cost of Natural Gas on the Consolidated Statements of Operations.
	From time to time, our various businesses, including the California Utilities, may use other energy derivatives to hedge exposures such as the price of vehicle fuel.
	In addition to the amounts noted above, we frequently use commodity derivatives to manage risks associated with the physical locations of our assets and other contractual obligations, such as natural gas purchases and sales.
	INTEREST RATE DERIVATIVES
	We are exposed to interest rates primarily as a result of our current and expected use of financing. We periodically enter into interest rate derivative agreements intended to moderate our exposure to interest rates and to lower our overall costs of borrowing. We utilize interest rate swaps typically designated as fair value hedges, as a means to achieve our targeted level of variable rate debt as a percent of total debt. In addition, we may utilize interest rate swaps, typically designated as cash flow hedges, to lock in interest rates on outstanding debt or in anticipation of future financings.
	Interest rate derivatives are utilized by the California Utilities as well as by other Sempra Energy subsidiaries. Although the California Utilities generally recover borrowing costs in rates over time, the use of interest rate derivatives is subject to certain regulatory constraints, and the impact of interest rate derivatives may not be recovered from customers as timely as described above with regard to natural gas derivatives. Interest rate derivatives are generally accounted for as hedges at the California Utilities, as well as at the rest of Sempra Energy’s subsidiaries. Separately, Otay Mesa VIE has entered into interest rate swap agreements to moderate its exposure to interest rate changes. This activity was designated as a cash flow hedge as of April 1, 2011.
	FOREIGN CURRENCY DERIVATIVES
	We are exposed to exchange rate movements at our Mexican subsidiaries, which have U.S. dollar denominated cash balances, receivables and payables (monetary assets and liabilities) that give rise to Mexican currency exchange rate movements for Mexican income tax purposes. These subsidiaries also have deferred income tax assets and liabilities that are denominated in the Mexican peso, which must be translated into U.S. dollars for financial reporting purposes. From time to time, we may utilize short-term foreign currency derivatives at our subsidiaries and at the consolidated level as a means to manage the risk of exposure to significant fluctuations in our income tax expense from these impacts. We may also utilize cross-currency swaps to hedge exposure related to Mexican peso-denominated debt at our Mexican subsidiaries and joint ventures. On February 14, 2013, Sempra Mexico entered into cross-currency swap agreements, which were designated as cash flow hedges.
	In addition, Sempra South American Utilities may utilize foreign currency derivatives at its subsidiaries and joint ventures as a means to manage foreign currency rate risk. We discuss such swaps at Chilquinta Energía’s Eletrans joint venture investment in Note 4.

FAIR_VALUE_MEASUREMENTS_Polici

Fair Value Measurements Policy [Abstract]
Fair Value Measurement Policy	Recurring Fair Value Measures
	The three tables below, by level within the fair value hierarchy, set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2014 and 2013. We classify financial assets and liabilities in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities, and their placement within the fair value hierarchy levels.
	The fair value of commodity derivative assets and liabilities is presented in accordance with our netting policy, as we discuss in Note 9 under “Financial Statement Presentation.”
	The determination of fair values, shown in the tables below, incorporates various factors, including but not limited to, the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits, letters of credit and priority interests).
	Our financial assets and liabilities that were accounted for at fair value on a recurring basis at December 31, 2014 and 2013 in the tables below include the following:
	Nuclear decommissioning trusts reflect the assets of SDG&E’s nuclear decommissioning trusts, excluding cash balances. A third party trustee values the trust assets using prices from a pricing service based on a market approach. We validate these prices by comparison to prices from other independent data sources. Equity and certain debt securities are valued using quoted prices listed on nationally recognized securities exchanges or based on closing prices reported in the active market in which the identical security is traded (Level 1). Other debt securities are valued based on yields that are currently available for comparable securities of issuers with similar credit ratings (Level 2).
	We enter into commodity contracts and interest rate derivatives primarily as a means to manage price exposures. We may also manage foreign exchange rate exposures using derivatives. We primarily use a market approach with market participant assumptions to value these derivatives. Market participant assumptions include those about risk, and the risk inherent in the inputs to the valuation techniques. These inputs can be readily observable, market corroborated, or generally unobservable. We have exchange-traded derivatives that are valued based on quoted prices in active markets for the identical instruments (Level 1). We also may have other commodity derivatives that are valued using industry standard models that consider quoted forward prices for commodities, time value, current market and contractual prices for the underlying instruments, volatility factors, and other relevant economic measures (Level 2). All Level 3 recurring items are related to CRRs at SDG&E, as we discuss below under “Level 3 Information.” We record commodity derivative contracts that are subject to rate recovery as commodity costs that are offset by regulatory account balances and are recovered in rates.
	Investments include marketable securities that we value using a market approach based on closing prices reported in the active market in which the identical security is traded (Level 1).
	SDG&E’s Energy and Fuel Procurement department, in conjunction with SDG&E’s finance group, is responsible for determining the appropriate fair value methodologies used to value and classify CRRs on an ongoing basis. Inputs used to determine the fair value of CRRs are reviewed and compared with market conditions to determine reasonableness. SDG&E expects all costs related to CRRs to be recoverable through customer rates. As such, there is no impact to earnings from changes in the fair value of these instruments.
	CRRs are recorded at fair value based almost entirely on the most current auction prices published by the California ISO, an objective source. The impact associated with discounting is negligible. Because auction prices are a less observable input, these instruments are classified as Level 3. At December 31, 2014, the auction prices ranged from $(16) per MWh to $8 per MWh at a given location, and the fair value of these instruments is derived from auction price differences between two locations. At December 31, 2013, the auction prices ranged from $(6) per MWh to $12 per MWh. Positive values between two locations represent expected future reductions in congestion costs, whereas negative values between two locations represent expected future charges. Valuation of our CRRs is sensitive to a change in auction price. If auction prices at one location increase (decrease) relative to another location, this could result in a higher (lower) fair value measurement. We summarize CRR volumes in Note 9. Realized gains and losses associated with CRRs are recorded in Cost of Electric Fuel and Purchased Power, which is recoverable in rates, on the Consolidated Statements of Operations. Unrealized gains and losses are recorded as regulatory assets and liabilities and therefore also do not affect earnings.
	Fair Value of Financial Instruments
	The fair values of certain of our financial instruments (cash, temporary investments, accounts and notes receivable, dividends and accounts payable, short-term debt and customer deposits) approximate their carrying amounts. Investments in life insurance contracts that we hold in support of our Supplemental Executive Retirement, Cash Balance Restoration and Deferred Compensation Plans are carried at cash surrender values, which represent the amount of cash that could be realized under the contracts.
	We base the fair value of certain long-term debt and preferred stock on a market approach using quoted market prices for identical or similar securities in thinly-traded markets (Level 2). We value other long-term debt using an income approach based on the present value of estimated future cash flows discounted at rates available for similar securities (Level 3).

SHAREHOLDERS_EQUITY_AND_EARNIN1

SHAREHOLDERS' EQUITY AND EARNINGS PER SHARE (Policies)	12 Months Ended
	Dec. 31, 2014
Earnings Per Share [Abstract]
Earnings Per Share, Policy [Text Block]	Basic EPS is calculated by dividing earnings attributable to common stock by the weighted-average number of common shares outstanding for the year. Diluted EPS includes the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
	The dilution from common stock options is based on the treasury stock method. Under this method, proceeds based on the exercise price plus unearned compensation and windfall tax benefits recognized, minus tax shortfalls recognized, are assumed to be used to repurchase shares on the open market at the average market price for the period. The windfall tax benefits are tax deductions we would receive upon the assumed exercise of stock options in excess of the deferred income taxes we recorded related to the compensation expense on the stock options. Tax shortfalls occur when the assumed tax deductions are less than recorded deferred income taxes. The calculation of dilutive common stock equivalents excludes options for which the exercise price on common stock was greater than the average market price during the period (out-of-the-money options).
	The dilution from unvested restricted stock awards (RSAs) and restricted stock units (RSUs) is also based on the treasury stock method. Proceeds equal to the unearned compensation and windfall tax benefits recognized, minus tax shortfalls recognized, related to the awards and units are assumed to be used to repurchase shares on the open market at the average market price for the period. The windfall tax benefits recognized or tax shortfalls recognized are the difference between tax deductions we would receive upon the assumed vesting of RSAs or RSUs and the deferred income taxes we recorded related to the compensation expense on such awards and units.
	Our RSAs, which are solely service-based, and those RSUs that are service-based or issued in connection with the creation of the Cameron LNG Holdings joint venture represent the right to receive up to 1.0 share over the course or at the end of the service period and have the same dividend equivalent rights as performance-based RSUs. We include RSAs and these RSUs in potential dilutive shares at 100 percent, subject to the application of the treasury stock method. We include our performance-based RSUs in potential dilutive shares at zero to up to 200 percent to the extent that they currently meet the performance requirements for vesting, subject to the application of the treasury stock method.

We grant credit to utility customers and counterparties, substantially all of whom are located in our service territory, which covers most of Southern California and a portion of central California for SoCalGas, and all of San Diego County and an adjacent portion of Orange County for SDG&E. We also grant credit to utility customers and counterparties of our other companies providing natural gas or electric services in Mexico, Chile, Peru, southwest Alabama, and Hattiesburg, Mississippi.
	When they become operational, projects owned or partially owned by Sempra Natural Gas, Sempra Renewables, Sempra South American Utilities and Sempra Mexico place significant reliance on the ability of their suppliers and customers to perform on long-term agreements and on our ability to enforce contract terms in the event of nonperformance. We consider many factors, including the negotiation of supplier and customer agreements, when we evaluate and approve development projects.
Environmental Policy [Abstract]
Environmental Costs, Policy	We generally capitalize the significant costs we incur to mitigate or prevent future environmental contamination or extend the life, increase the capacity, or improve the safety or efficiency of property used in current operations.
	At the California Utilities, costs that relate to current operations or an existing condition caused by past operations are generally recorded as a regulatory asset due to the probability that these costs will be recovered in rates.
	We record environmental liabilities at undiscounted amounts when our liability is probable and the costs can be reasonably estimated. In many cases, however, investigations are not yet at a stage where we can determine whether we are liable or, if the liability is probable, to reasonably estimate the amount or range of amounts of the costs. Estimates of our liability are further subject to uncertainties such as the nature and extent of site contamination, evolving cleanup standards and imprecise engineering evaluations. We review our accruals periodically and, as investigations and cleanup proceed, we make adjustments as necessary.
Legal Costs Policy [Abstract]
Legal Fees, Policy	LEGAL FEES
	Legal fees that are associated with a past event for which a liability has been recorded are accrued when it is probable that fees also will be incurred.
	LEGAL PROCEEDINGS
	We accrue losses for a legal proceeding when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. However, the uncertainties inherent in legal proceedings make it difficult to estimate with reasonable certainty the costs and effects of resolving these matters. Accordingly, actual costs incurred may differ materially from amounts accrued, may exceed applicable insurance coverage and could materially adversely affect our business, cash flows, results of operations, financial condition and prospects. Unless otherwise indicated, we are unable to estimate reasonably possible losses in excess of any amounts accrued.

	-2	Reclassification to liability held for sale - asset retirement obligation which is included in Other Current Liabilities on the Consolidated Balance Sheets, as we discuss in "Asset Held for Sale" in Note 3.
	-3	The decreases in asset retirement obligations in 2013 at SDG&E and SoCalGas are due to revised estimates related to the 2012 General Rate Case (GRC) that received final approval in May 2013. At SDG&E, these revisions included increases in asset service lives ranging from 2 percent to 7 percent, and lower estimated cost of removal. At SoCalGas, the decrease includes increases in asset service lives ranging from 4 percent to 6 percent, partially offset by a higher estimated cost of removal.
	-4	The decrease in asset retirement obligations in 2014 at SDG&E is due to revised estimates in an updated decommissioning cost study for the San Onofre Nuclear Generating Station, which we discuss in Note 13. The increase in asset retirement obligations in 2014 at SoCalGas is related to a change in estimates.
	-5	The increase in asset retirement obligations in 2013 at SDG&E is due to revised estimates recorded in the third quarter of 2013 related to the early decommissioning of SONGS Units 2 and 3 (see Note 13).

[2]	Reclassification to liability held for sale - asset retirement obligation which is included in Other Current Liabilities on the Consolidated Balance Sheets, as we discuss in "Asset Held for Sale" in Note 3.
[3]	The decreases in asset retirement obligations in 2013 at SDG&E and SoCalGas are due to revised estimates related to the 2012 General Rate Case (GRC) that received final approval in May 2013. At SDG&E, these revisions included increases in asset service lives ranging from 2 percent to 7 percent, and lower estimated cost of removal. At SoCalGas, the decrease includes increases in asset service lives ranging from 4 percent to 6 percent, partially offset by a higher estimated cost of removal.
[4]	The decrease in asset retirement obligations in 2014 at SDG&E is due to revised estimates in an updated decommissioning cost study for the San Onofre Nuclear Generating Station, which we discuss in Note 13. The increase in asset retirement obligations in 2014 at SoCalGas is related to a change in estimates.
[5]	The increase in asset retirement obligations in 2013 at SDG&E is due to revised estimates recorded in the third quarter of 2013 related to the early decommissioning of SONGS Units 2 and 3 (see Note 13).

[2]	This includes $7 million at SDG&E and $24 million at SoCalGas related to hazardous waste sites subject to the Hazardous Waste Collaborative mechanism approved by the CPUC in 1994. This mechanism permits Californiabs IOUs, including the California Utilities, to recover in rates 90 percent of hazardous waste cleanup costs and related third-party litigation costs, and 70 percent of the related insurance-litigation expenses for certain sites. In addition, the California Utilities have the opportunity to retain a percentage of any recoveries from insurance carriers and other third parties to offset the cleanup and associated litigation costs not recovered in rates.
[3]	There may be on-going compliance obligations for completed sites, such as regular inspections, adherence to land use covenants and water quality monitoring.
