Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Organization and Basis of Presentation Edison International is the parent holding company of Southern California Edison Company ("SCE") and Edison Energy Group, Inc. ("Edison Energy Group"). SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity to an approximately 50,000 square mile area of southern California. Edison Energy Group is a holding company for Edison Energy, LLC ("Edison Energy") which is engaged in the competitive business of providing data-driven energy solutions to commercial, institutional and industrial customers. Edison Energy's business activities are currently not material to report as a separate business segment. These combined notes to the consolidated financial statements apply to both Edison International and SCE unless otherwise described. Edison International's consolidated financial statements include the accounts of Edison International, SCE and other wholly owned and controlled subsidiaries. References to Edison International refer to the consolidated group of Edison International and its subsidiaries. References to "Edison International Parent and Other" refer to Edison International Parent and its competitive subsidiaries and "Edison International Parent" refer to Edison International on a stand-alone basis, not consolidated with its subsidiaries. SCE's consolidated financial statements include the accounts of SCE and its wholly owned and controlled subsidiaries. All intercompany transactions have been eliminated from the consolidated financial statements. Edison International's and SCE's accounting policies conform to accounting principles generally accepted in the United States of America, including the accounting principles for rate-regulated enterprises, which reflect the ratemaking policies of the California Public Utility Commission ("CPUC") and the Federal Energy Regulatory Commission ("FERC"). SCE applies authoritative guidance for rate-regulated enterprises to the portion of its operations in which regulators set rates at levels intended to recover the estimated costs of providing service, plus a return on net investments in assets, or rate base. Regulators may also impose certain penalties or grant certain incentives. Due to timing and other differences in the collection of electric utility revenue, these principles require an incurred cost that would otherwise be charged to expense by a non-regulated entity to be capitalized as a regulatory asset if it is probable that the cost is recoverable through future rates; and conversely the principles require recording of a regulatory liability for amounts collected in rates to recover costs expected to be incurred in the future or amounts collected in excess of costs incurred and refundable to customers. In addition, SCE recognizes revenue and regulatory assets from alternative revenue programs, which enables the utility to adjust future rates in response to past activities or completed events, if certain criteria are met, even for programs that do not qualify for recognition of "traditional" regulatory assets and liabilities. SCE assesses, at the end of each reporting period, whether regulatory assets are probable of future recovery. See Note 11 for composition of regulatory assets and liabilities. The preparation of financial statements in conformity with United States generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reported period. Actual results could differ from those estimates. Certain prior year amounts have been conformed to the current year's presentation, including the presentation of long-term insurance receivables on the consolidated balance sheets of Edison International and Southern California Edison, previously presented as other long-term assets. Cash, Cash Equivalents and Restricted Cash Cash equivalents include investments in money market funds. Generally, the carrying value of cash equivalents equals the fair value, as these investments have original maturities of three months or less. The cash equivalents were as follows: Edison International SCE December 31, (in millions) 2020 2019 2020 2019 Money market funds $ 62 $ 31 $ 38 $ — Cash is temporarily invested until required for check clearing. Checks issued, but not yet paid by the financial institution, are reclassified from cash to accounts payable at the end of each reporting period as follows: Edison International SCE December 31, (in millions) 2020 2019 2020 2019 Book balances reclassified to accounts payable $ 69 $ 75 $ 69 $ 74 The following table sets forth the cash, cash equivalents and restricted cash included in the consolidated statements of cash flows: (in millions) December 31, 2020 December 31, 2019 Edison International: Cash and cash equivalents $ 87 $ 68 Short-term restricted cash 1 2 2 Total cash, cash equivalents, and restricted cash $ 89 $ 70 SCE: Cash and cash equivalents $ 55 $ 24 Short-term restricted cash 1 1 — Total cash, cash equivalents, and restricted cash $ 56 $ 24 1 Reflected in "Other current assets" on Edison International's and SCE's consolidated balance sheets. Allowance for Uncollectible Accounts The allowance for uncollectible accounts is recorded based on SCE's estimate of expected credit losses and adjusted over the life of the receivables as needed. Since the customer base of SCE is concentrated in Southern California and exposes SCE to a homogeneous set of economic conditions, the allowance is measured on a collective basis on the historical amounts written-off, assessment of customer collectibility and current economic trends, including unemployment rates and any likelihood of recession for the region. At December 31, 2020, this included the estimated impacts of the COVID-19 pandemic. The following table sets forth the changes in allowance for uncollectible accounts for SCE: Year ended December 31, 2020 (in millions) Customers All others Beginning balance $ 35 $ 14 Plus: current period provision for uncollectible accounts Included in operation and maintenance expenses 36 9 Deferred to regulatory assets 120 — Less: write-offs, net of recoveries 16 10 Ending balance $ 175 $ 13 Inventory SCE's inventory is primarily composed of materials, supplies and spare parts, and generally stated at weighted average cost. Emission Allowances and Energy Credits SCE is allocated greenhouse gas ("GHG") allowances annually which it is then required to sell into quarterly auctions. GHG proceeds from the auctions are recorded as a regulatory liability to be refunded to customers. SCE purchases GHG allowances in quarterly auctions or from counterparties to satisfy its GHG emission compliance obligations and recovers such costs of GHG allowances from customers. GHG allowances held for use are classified as "Other current assets" on the consolidated balance sheets and are stated, similar to an inventory method, at the lower of weighted average cost or market. SCE had GHG allowances held for use of $78 million and $50 million at December 31, 2020 and 2019, respectively. GHG emission obligations were $64 million and $50 million at December 31, 2020 and 2019, respectively, and are classified as "Other current liabilities" on the consolidated balance sheets. SCE is allocated low carbon fuel standard ("LCFS") credits which it sells to market participants. Proceeds from the sales, net of program costs, are recorded in a balancing account to be refunded to eligible customers. SCE's net proceeds from the sale of these LCFS credits were $176 million and $184 million and are classified as "Regulatory liabilities" on the consolidated balance sheets at December 31, 2020 and 2019, respectively. Property, Plant and Equipment SCE plant additions, including eligible replacements and betterments, are capitalized. Direct material and labor and indirect costs such as construction overhead, administrative and general costs, pension and benefits, and property taxes are capitalized as part of plant additions. The CPUC authorizes a capitalization rate for each of the indirect costs which are allocated to each project based on either labor or total costs. Estimated useful lives authorized by the CPUC in the 2018 General Rate Case ("GRC") and weighted average useful lives of SCE's property, plant and equipment, are as follows: Estimated Useful Lives Weighted Average Useful Lives Generation plant 10 years to 55 years 36 years Distribution plant 20 years to 65 years 48 years Transmission plant 45 years to 65 years 54 years General plant and other 5 years to 60 years 25 years Depreciation of utility property, plant and equipment is computed on a straight-line, remaining-life basis. SCE's depreciation expense was $1.8 billion, $1.7 billion and $1.7 billion for 2020, 2019 and 2018, respectively. Depreciation expense stated as a percent of average original cost of depreciable utility plant was, on a composite basis, 3.6%, 3.6% and 3.7% for 2020, 2019 and 2018, respectively. The original costs of retired property are charged to accumulated depreciation. See Note 2 for further information. Nuclear fuel for the Palo Verde Nuclear Generating Station ("Palo Verde") is recorded as utility plant (nuclear fuel in the fabrication and installation phase is recorded as construction in progress) in accordance with CPUC ratemaking procedures. Palo Verde nuclear fuel is amortized using the units of production method. Allowance for funds used during construction ("AFUDC") represents the estimated cost of debt and equity funds that finance utility-plant construction and is capitalized during certain plant construction. AFUDC is recovered in rates through depreciation expense over the useful life of the related asset. AFUDC equity represents a method to compensate SCE for the estimated cost of equity used to finance utility plant additions and is recorded as part of construction in progress. AFUDC equity was $121 million, $101 million and $104 million in 2020, 2019 and 2018, respectively, and is reflected in "Other income." AFUDC debt was $53 million, $63 million and $44 million in 2020, 2019 and 2018, respectively and is reflected as a reduction of "Interest expense." Major Maintenance Major maintenance costs for SCE's power plant facilities and equipment are expensed as incurred. Impairment of Long-Lived Assets Impairments of long-lived assets are evaluated based on a review of estimated future cash flows expected to be generated whenever events or changes in circumstances indicate that the carrying amount of such investments or assets may not be recoverable. If the carrying amount of a long-lived asset exceeds expected future cash flows, undiscounted and without interest charges, an impairment loss is recognized in the amount of the excess of fair value over the carrying amount. Fair value is determined via market, cost and income-based valuation techniques, as appropriate. Accounting principles for rate-regulated enterprises also require recognition of an impairment loss if it becomes probable that the regulated utility will abandon a plant investment, or if it becomes probable that the cost of a recently completed plant will be disallowed, either directly or indirectly, for ratemaking purposes and a reasonable estimate of the amount of the disallowance can be made. Initial and annual contributions to the wildfire insurance fund established pursuant to California Assembly Bill 1054 (the "Wildfire Insurance Fund" and "AB 1054") Edison International and SCE accounted for the contributions to the Wildfire Insurance Fund similarly to prepaid insurance. No period of coverage was provided in AB 1054, therefore expense is being allocated to periods ratably based on an estimated period of coverage. Edison International and SCE have a $2.4 billion and $2.8 billion long-term asset at December 31, 2020 and December 31, 2019, respectively, and a $323 million current asset reflected as "Wildfire Insurance Fund contributions" in the consolidated balance sheets for the initial $2.4 billion contribution made during the third quarter of 2019 and the present value of annual contributions SCE committed to make to the Wildfire Insurance Fund, reduced by amortization at both December 31, 2020 and December 31, 2019. A long-term liability of $703 million and $785 million have been reflected in "Other deferred credits and other long-term liabilities" for the present value of unpaid contribution amounts, at December 31, 2020 and December 31, 2019, respectively. Contributions were discounted to the present value at the date SCE committed to participate in the Wildfire Insurance Fund using US treasury interest rates. During 2020 a period of 10 years was used to amortize the asset. All expenses related to the contributions are being reflected in "Operation and maintenance" in the consolidated statements of income. Changes in the estimated period of coverage provided by the Wildfire Insurance Fund could lead to material changes in future expense recognition. In estimating the period of coverage Edison International and SCE used Monte Carlo simulations based on five years (2014 – 2018) of historical data from wildfires caused by electrical utility equipment to estimate expected losses. The details of the operation of the Wildfire Insurance Fund and estimates related to claims by SCE, Pacific Gas & Electric Company ("PG&E") and San Diego Gas & Electric ("SDG&E") against the fund have been applied to the expected loss simulations to estimate the period of coverage of the fund. The most sensitive inputs to the estimated period of coverage are the expected frequency of wildfire events caused by investor-owned utility electrical equipment and the estimated costs associated with those forecasted events. Edison International and SCE evaluate all inputs annually, or upon claims being made from the fund for catastrophic wildfires, and the expected life of the insurance fund will be adjusted as required. Based on information available in the first quarter of 2021 regarding catastrophic wildfires during 2019 and 2020, SCE reassessed its estimate of the life of the Wildfire Insurance Fund. Using 7 years of historical data (2014 – 2020) of wildfires caused by electrical utility equipment to create Monte Carlo simulations of expected loss, resulted in the expected life of the Wildfire Insurance Fund increasing from 10 years to 15 years from the date SCE committed to participate in the Wildfire Insurance Fund. Edison International and SCE will assess the Wildfire Insurance Fund contribution assets for impairment in the event that a participating utility's electrical equipment is found to be the substantial cause of a catastrophic wildfire, based on the ability of SCE to benefit from the coverage provided by the Wildfire Insurance Fund in an amount equal to the recorded assets. Goodwill Edison International assesses goodwill through an annual goodwill impairment test, at the reporting unit level as of October 1 of each year. Edison International updates its goodwill impairment test between annual tests if events occur or circumstances change such that it is more likely than not that the fair value of a reporting unit is below its carrying value. In June 2020, the goodwill associated with Edison Energy was fully impaired primarily from the economic impact of COVID-19. During the second quarter of 2020 and in the fourth quarter of 2019 and 2018, Edison International recorded an impairment of its Edison Energy reporting unit goodwill totaling $34 million ($25 million after-tax), $25 million ($18 million after-tax), $19 million ($13 million after-tax), respectively. At December 31, 2020 and December 31, 2019, Edison International had no remaining goodwill and $34 million of goodwill, respectively, all of which is related to its Edison Energy reporting unit. Nuclear Decommissioning and Asset Retirement Obligations The fair value of a liability for an asset retirement obligation ("ARO") is recorded in the period in which it is incurred, including a liability for the fair value of a conditional ARO, if the fair value can be reasonably estimated even though uncertainty exists about the timing and/or method of settlement. When an ARO liability is initially recorded, SCE capitalizes the cost by increasing the carrying amount of the related long-lived asset. For each subsequent period, the liability is increased for accretion expense and the capitalized cost is depreciated over the useful life of the related asset. SCE has not recorded an ARO for assets that are expected to operate indefinitely or where SCE cannot estimate a settlement date (or range of potential settlement dates). As such, ARO liabilities are not recorded for certain retirement activities, including certain hydroelectric facilities. The following table summarizes the changes in SCE's ARO liability: December 31, (in millions) 2020 2019 Beginning balance $ 3,029 $ 3,031 Accretion 1 160 166 Revisions (36) 4 Liabilities settled (223) (172) Ending balance $ 2,930 $ 3,029 1 An ARO represents the present value of a future obligation. Accretion is an increase in the liability to account for the time value of money resulting from discounting. AROs related to decommissioning of SCE's nuclear power facilities are based on site-specific studies conducted as part of each Nuclear Decommissioning Cost Triennial Proceeding ("NDCTP") conducted before the CPUC. Revisions of an ARO are established for updated site-specific decommissioning cost estimates. The ARO for decommissioning SCE's San Onofre Nuclear Generating Station ("San Onofre") and Palo Verde nuclear power facilities is $2.6 billion as of December 31, 2020. The liability to decommission SCE's nuclear power facilities is based on a 2017 decommissioning study that was filed as part of the 2018 NDCTP for San Onofre Units 1, 2 and 3, and a 2019 decommissioning study for Palo Verde. SCE revised the ARO for Palo Verde in 2020 and for San Onofre Units 1, 2 and 3 in 2018 to reflect updated decommissioning cost estimates. SCE records an ARO regulatory liability as a result of timing differences between the recognition of costs and the recovery of costs through the ratemaking process. For further information, see Note 11. Decommissioning of San Onofre Unit 1 began in 1999 and the transfer of spent nuclear fuel from Unit 1 to dry cask storage in the Independent Spent Fuel Storage Installation ("ISFSI") was completed in 2005. Major decommissioning work for Unit 1 has been completed except for certain underground work. Decommissioning of San Onofre Units 2 and 3 began in June 2013 and the spent nuclear fuel transfer from San Onofre Units 2 and 3 to dry cask storage in the ISFSI was completed in August 2020. In October 2019, the California Coastal Commission approved SCE's application for the Coastal Development Permit, the principal discretionary permit required to start major decommissioning activities at San Onofre. In August 2020, SCE commenced major decommissioning activities at San Onofre in accordance with the terms of the permit. Decommissioning costs, which are recovered through customer rates over the term of each nuclear facility's operating license, are recorded as a component of depreciation expense, with a corresponding credit to the ARO regulatory liability. Due to regulatory recovery of SCE's nuclear decommissioning expense, prudently incurred costs for nuclear decommissioning activities do not affect SCE's earnings. Amortization of the ARO asset (included within the unamortized nuclear investment) and accretion of the ARO liability are deferred as decreases to the ARO regulatory liability account, resulting in no impact on earnings. SCE has collected in rates amounts for the future decommissioning of its nuclear assets and has placed those amounts in independent trusts. Amounts collected in rates in excess of the ARO liability are classified as regulatory liabilities. Changes in the estimated costs, timing of decommissioning or the assumptions underlying these estimates could cause material revisions to the estimated total cost to decommission. SCE currently estimates that it will spend approximately $6.6 billion through 2079 to decommission its nuclear facilities. This estimate is based on SCE's decommissioning cost methodology used for ratemaking purposes, escalated at rates ranging from 0.6% to 7.5% (depending on the cost element) annually. These costs are expected to be funded from independent decommissioning trusts. SCE estimates annual after-tax earnings on the decommissioning funds of 1.3% to 4.1% dependent on asset class. If the assumed return on trust assets is not earned or costs escalate at higher rates, SCE expects that additional funds needed for decommissioning will be recoverable through future rates, subject to a reasonableness review. See Note 10 for further information. Due to regulatory recovery of SCE's nuclear decommissioning expense, prudently incurred costs for nuclear decommissioning activities do not affect SCE's earnings. SCE's nuclear decommissioning costs are subject to CPUC review through the triennial regulatory proceeding. SCE's nuclear decommissioning trust investments primarily consist of fixed income investments that are classified as available-for-sale and equity investments. Due to regulatory mechanisms, investment earnings and realized gains and losses have no impact on earnings. Unrealized gains and losses on decommissioning trust funds, including impairment, increase or decrease the trust assets and the related regulatory asset or liability and have no impact on electric utility revenue or decommissioning expense. SCE reviews each fixed income security for impairment on the last day of each month. If the fair value on the last day of the month is less than the amortized cost for that security, SCE impairs the disclosed amortized cost. If the fair value is greater or less than the carrying value for that security at the time of sale, SCE recognizes a related realized gain or loss, respectively. Deferred Financing Costs Debt premium, discount and issuance expenses incurred in connection with obtaining financing are deferred and amortized on a straight-line basis. Under CPUC ratemaking procedures, SCE's debt reacquisition expenses are amortized over the remaining life of the reacquired debt or, if refinanced, the life of the new debt. SCE had unamortized losses on reacquired debt of $133 million and $142 million at December 31, 2020 and 2019, respectively, reflected as long-term "Regulatory assets" in the consolidated balance sheets. In addition, Edison International and SCE had debt issuance costs related to issuances of long-term debt of $131 million and $117 million at December 31, 2020, respectively, and $121 million and $106 million at December 31, 2019, respectively, reflected as a reduction of "Long-term debt" on the consolidated balance sheets. Amortization of deferred financing costs charged to interest expense is as follows: Edison International SCE Years ended December 31, (in millions) 2020 2019 2018 2020 2019 2018 Amortization of deferred financing costs charged to interest expense $ 32 $ 30 $ 30 $ 27 $ 26 $ 26 Revenue Recognition Revenue is recognized by Edison International and SCE when a performance obligation to transfer control of the promised goods is satisfied or when services are rendered to customers. This typically occurs when electricity is delivered to customers, which includes amounts for services rendered but unbilled at the end of a reporting period. SCE's Revenue from Contracts with Customers Provision of Electricity SCE principally generates revenue through supplying and delivering electricity to its customers. Rates charged to customers are based on tariff rates, approved by the CPUC and FERC. Starting with SCE's 2021 GRC, revenue will be authorized through quadrennial GRC proceedings, which are intended to provide SCE a reasonable opportunity to recover its costs and earn a return on its CPUC-jurisdictional rate base. The CPUC sets an annual revenue requirement for the base year and the remaining three years are set by a methodology established in the GRC proceeding. Revenue was previously authorized by the CPUC in triennial GRC proceedings. As described above, SCE also earns revenue, with no return, to recover costs for power procurement and other activities. Revenue is authorized by the FERC through a formula rate which is intended to provide SCE a reasonable opportunity to recover transmission capital and operating costs that are prudently incurred, including a return on its FERC-jurisdictional rate base. Under the operation of the formula rate, transmission revenue is updated to actual cost of service annually. For SCE's electricity sales for both residential and non-residential customers, SCE satisfies the performance obligation of delivering electricity over time as the customers simultaneously receive and consume the delivered electricity. Energy sales are typically on a month-to-month implied contract for transmission, distribution and generation services. Revenue is recognized over time as the energy is supplied and delivered to customers and the respective revenue is billed and paid on a monthly basis. CPUC and FERC rates decouple authorized revenue from the volume of electricity sales and the price of energy procured so that SCE receives revenue equal to amounts authorized by the relevant regulatory agencies. As a result, the volume of electricity sold to customers and specific customer classes does not have a direct impact on SCE's financial results. See Note 7 for further information on SCE's revenue. Sales and Use Taxes SCE bills certain sales and use taxes levied by state or local governments to its customers. Included in these sales and use taxes are franchise fees, which SCE pays to various municipalities (based on contracts with these municipalities) in order to operate within the limits of the municipality. SCE bills these franchise fees to its customers based on a CPUC-authorized rate. These franchise fees, which are required to be paid regardless of SCE's ability to collect from the customer, are accounted for on a gross basis. SCE's franchise fees billed to customers were $131 million, $122 million and $133 million for the years ended December 31, 2020, 2019 and 2018, respectively. When SCE acts as an agent for sales and use tax, the taxes are accounted for on a net basis. Amounts billed to and collected from customers for these taxes are remitted to the taxing authorities and are not recognized as electric utility revenue. SCE's Alternative Revenue Programs The CPUC and FERC have authorized additional, alternative revenue programs which adjust billings for the effects of broad external factors or compensate SCE for demand-side management initiatives and provide for incentive awards if SCE achieves certain objectives. These alternative revenue programs allow SCE to recover costs that SCE has been authorized to pass on to customers, including costs to purchase electricity and natural gas, and to fund public purpose, demand response, and customer energy efficiency programs. In general, revenue is recognized for these alternative revenue programs at the time the costs are incurred and, for incentive-based programs, at the time the awards are approved by the CPUC. SCE begins recognizing revenues for these programs when a program has been established by an order from either the CPUC or FERC that allows for automatic adjustment of future rates, the amount of revenue for the period is objectively determinable and probable of recovery and the revenue will be collected within 24 months following the end of the annual period. Regulatory Proceedings 2018 General Rate Case In May 2019, the CPUC approved a final decision in SCE's 2018 GRC. The revenue requirements in the 2018 GRC final decision are retroactive to January 1, 2018. SCE recorded the prior period impact of the 2018 GRC final decision in 2019 including: • An increase to earnings of $65 million attributable to 2018 from the application of the decision to revenue, depreciation expense and income tax expense. The reduction of revenue of $289 million reflected the lower authorized revenue related to 2018. • An impairment of utility property, plant and equipment of $170 million ($123 million after-tax) related to disallowed historical capital expenditures, primarily the write-off of specific pole replacements the CPUC determined were performed prematurely. 2021 General Rate Case In the 2021 GRC, SCE has requested a test year revenue requirement of $7.6 billion, an approximately $1.3 billion increase over the 2020 revenue requirement authorized in the 2018 GRC as updated for post test-year ratemaking changes. SCE believes that receiving a proposed decision on track 1 of the 2021 GRC in the first quarter of 2021 in line with the CPUC’s schedule for track 1 is unlikely. The CPUC has approved the establishment of a memorandum account making the authorized revenue requirement changes effective January 1, 2021. SCE cannot predict the revenue requirement the CPUC will ultimately authorize or forecast the timing of a final decision. SCE expects to recognize revenue based on the 2020 authorized revenue requirement until a GRC decision is issued. Power Purchase Agreements SCE enters into power purchase agreements ("PPAs") in the normal course of business. A power purchase agreement may be considered a variable interest in a variable interest entity ("VIE"). If SCE is the primary beneficiary in the VIE, SCE should consolidate the VIE. None of SCE's PPAs resulted in consolidation of a VIE at December 31, 2020 and 2019. See Note 3 for further discussion of PPAs that are considered variable interests. A PPA may also contain a lease for accounting purposes. See "Leases" below and Note 12 and Note 13 for further discussion of SCE's PPAs, including agreements that are classified as operating and finance leases for accounting purposes. A PPA that does not contain a lease may be classified as a derivative which is recorded at fair value on the consolidated balance sheets. These PPAs may be eligible for an election to designate as a normal purchase and sale, which is accounted for on an accrual basis as an executory contract. See Note 6 for further information on derivative instruments. PPAs that do not meet the above classifications are accounted for on an accrual basis. Derivative Instruments SCE records derivative instruments on its consolidated balance sheets as either assets or liabilities measured at fair value unless otherwise exempted from derivative treatment as normal purchases or sales. The normal purchases and sales exception requires, among other things, physical delivery in quantities expected to be used or sold over a reasonable period in the normal course of business. Realized gains and losses from SCE's derivative instruments are expected to be recovered from or refunded to customers through regulatory mechanisms and, therefore, SCE's fair value changes have no impact on purchased power expense or earnings. SCE does not use hedge accounting for derivative transactions due to regulatory accounting treatment. Where SCE's derivative instruments are subject to a master netting agreement and certain criteria are met, SCE presents its derivative assets and liabilities on a net basis on its consolidated balance sheets. In addition, derivative positions are offset against margin and cash collateral deposits. The results of derivative activities are recorded as part of cash flows from operating activities on the consolidated statements of cash flows. See Note 6 for further information on derivative instruments. Leases On January 1, 2019, Edison International and SCE adopted accounting standards updates that require lessees to recognize a lease on the balance sheet as a right-of-use ("ROU") asset and related lease liability and classify the lease as either operating or finance. A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified assets for a period of time in exchange for consideration. An entity controls the use when it has a right to obtain substantially all of the benefits from the use of the identified asset and has the right to direct the use of the asset. SCE determines if an arrangement is a lease at contract inception. SCE includes both the lease and non-lease components as a single component and |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Variable Interest Entities | Variable Interest Entities A VIE is defined as a legal entity that meets one of two conditions: (1) the equity owners do not have sufficient equity at risk, or (2) the holders of the equity investment at risk, as a group, lack any of the following three characteristics: decision-making rights, the obligation to absorb losses, or the right to receive the expected residual returns of the entity. The primary beneficiary is identified as the variable interest holder that has both the power to direct the activities of the VIE that most significantly impact the entity's economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. The primary beneficiary is required to consolidate the VIE. Commercial and operating activities are generally the factors that most significantly impact the economic performance of such VIEs. Commercial and operating activities include construction, operation and maintenance, fuel procurement, dispatch and compliance with regulatory and contractual requirements. Variable Interest in VIEs that are not Consolidated Power Purchase Agreements SCE has PPAs that are classified as variable interests in VIEs, including agreements through which SCE provides the natural gas to fuel the plants and fixed price contracts for renewable energy. SCE has concluded that it is not the primary beneficiary of these VIEs since it does not control the commercial and operating activities of these entities. Since payments for capacity are the primary source of income, the most significant economic activity for these VIEs is the operation and maintenance of the power plants. As of the balance sheet date, the carrying amount of assets and liabilities in SCE's consolidated balance sheets that relate to involvement with VIEs result from amounts due under the PPAs. Under these contracts, SCE recovers the costs incurred through demonstration of compliance with its CPUC-approved long-term power procurement plans. SCE has no residual interest in the entities and has not provided or guaranteed any debt or equity support, liquidity arrangements, performance guarantees or other commitments associated with these contracts other than the purchase commitments described in Note 12. As a result, there is no significant potential exposure to loss to SCE from its variable interest in these VIEs. The aggregate contracted capacity dedicated to SCE from these VIE projects was 5,103 megawatts ("MW") and 4,497 MW at December 31, 2020 and 2019, respectively, and the amounts that SCE paid to these projects were $744 million and $833 million for the years ended December 31, 2020 and 2019, respectively. These amounts are recoverable in customer rates, subject to reasonableness review. Unconsolidated Trusts of SCE SCE Trust II, Trust III, Trust IV, Trust V and Trust VI were formed in 2013, 2014, 2015, 2016 and 2017, respectively, for the exclusive purpose of issuing the 5.10%, 5.75%, 5.375%, 5.45% and 5.00% trust preference securities, respectively ("trust securities"). The trusts are VIEs. SCE has concluded that it is not the primary beneficiary of these VIEs as it does not have the obligation to absorb the expected losses or the right to receive the expected residual returns of the trusts. SCE Trust II, Trust III, Trust IV, Trust V and Trust VI issued to the public trust securities in the face amounts of $400 million, $275 million, $325 million, $300 million and $475 million (cumulative, liquidation amounts of $25 per share), respectively, and $10,000 of common stock each to SCE. The trusts invested the proceeds of these trust securities in Series G, Series H, Series J, Series K and Series L Preference Stock issued by SCE in the principal amounts of $400 million, $275 million, $325 million, $300 million and $475 million (cumulative, $2,500 per share liquidation values), respectively, which have substantially the same payment terms as the respective trust securities. The Series G, Series H, Series J, Series K and Series L Preference Stock and the corresponding trust securities do not have a maturity date. Upon any redemption of any shares of the Series G, Series H, Series J, Series K or Series L Preference Stock, a corresponding dollar amount of trust securities will be redeemed by the applicable trust (see Note 14 for further information). The applicable trust will make distributions at the same rate and on the same dates on the applicable series of trust securities if and when the SCE board of directors declares and makes dividend payments on the related Preference Stock. The applicable trust will use any dividends it receives on the related Preference Stock to make its corresponding distributions on the applicable series of trust securities. If SCE does not make a dividend payment to any of these trusts, SCE would be prohibited from paying dividends on its common stock. SCE has fully and unconditionally guaranteed the payment of the trust securities and trust distributions, if and when SCE pays dividends on the related Preference Stock. In September 2020, SCE Trust II redeemed $180 million of its trust securities from the public. The Trust II balance sheets as of December 31, 2020 and December 31, 2019 consisted of investments of $220 million and $400 million in the Series G Preference Stock, respectively, $220 million and $400 million of trust securities, respectively, and $10,000 each of common stock. The Trust III, Trust IV, Trust V and Trust VI balance sheets as of December 31, 2020 and December 31, 2019 consisted of investments of $275 million, $325 million, $300 million, and $475 million in the Series H, Series J, Series K and Series L Preference Stock, respectively, $275 million, $325 million, $300 million, and $475 million of trust securities, respectively, and $10,000 each of common stock.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements Recurring Fair Value Measurements 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 (referred to as an "exit price"). Fair value of an asset or liability considers assumptions that market participants would use in pricing the asset or liability, including assumptions about nonperformance risk. As of December 31, 2020 and 2019, nonperformance risk was not material for Edison International and SCE. Assets and liabilities are categorized into a three-level fair value hierarchy based on valuation inputs used to determine fair value. Level 1 – The fair value of Edison International's and SCE's Level 1 assets and liabilities is determined using unadjusted quoted prices in active markets that are available at the measurement date for identical assets and liabilities. This level includes exchange-traded equity securities, U.S. treasury securities, mutual funds and money market funds. Level 2 – Edison International's and SCE's Level 2 assets and liabilities include fixed income securities, primarily consisting of U.S. government and agency bonds, municipal bonds and corporate bonds, and over-the-counter derivatives. The fair value of fixed income securities is determined using a market approach by obtaining quoted prices for similar assets and liabilities in active markets and inputs that are observable, either directly or indirectly, for substantially the full term of the instrument. The fair value of SCE's over-the-counter derivative contracts is determined using an income approach. SCE uses standard pricing models to determine the net present value of estimated future cash flows. Inputs to the pricing models include forward published or posted clearing prices from an exchange (Intercontinental Exchange) for similar instruments and discount rates. A primary price source that best represents trade activity for each market is used to develop observable forward market prices in determining the fair value of these positions. Broker quotes, prices from exchanges or comparison to executed trades are used to validate and corroborate the primary price source. These price quotations reflect mid-market prices (average of bid and ask) and are obtained from sources believed to provide the most liquid market for the commodity. Level 3 – The fair value of SCE's Level 3 assets and liabilities is determined using the income approach through various models and techniques that require significant unobservable inputs. This level includes derivative contracts that trade infrequently such as congestion revenue rights ("CRRs"). Edison International Parent and Other does not have any Level 3 assets and liabilities. Assumptions are made in order to value derivative contracts in which observable inputs are not available. In circumstances where fair value cannot be verified with observable market transactions, it is possible that a different valuation model could produce a materially different estimate of fair value. Modeling methodologies, inputs, and techniques are reviewed and assessed as markets continue to develop and more pricing information becomes available and the fair value is adjusted when it is concluded that a change in inputs or techniques would result in a new valuation that better reflects the fair value of those derivative contracts. See Note 6 for a discussion of derivative instruments. SCE The following table sets forth assets and liabilities of SCE that were accounted for at fair value by level within the fair value hierarchy: December 31, 2020 (in millions) Level 1 Level 2 Level 3 Netting and Collateral 1 Total Assets at fair value Derivative contracts $ — $ 6 $ 120 $ (18) $ 108 Other 39 23 — — 62 Nuclear decommissioning trusts: Stocks 2 1,908 — — — 1,908 Fixed Income 3 519 2,113 — — 2,632 Short-term investments, primarily cash equivalents 447 52 — — 499 Subtotal of nuclear decommissioning trusts 4 2,874 2,165 — — 5,039 Total assets 2,913 2,194 120 (18) 5,209 Liabilities at fair value Derivative contracts — 10 12 (22) — Total liabilities — 10 12 (22) — Net assets $ 2,913 $ 2,184 $ 108 $ 4 $ 5,209 December 31, 2019 (in millions) Level 1 Level 2 Level 3 Netting and Collateral 1 Total Assets at fair value Derivative contracts $ — $ 19 $ 83 $ (15) $ 87 Other 4 14 — — 18 Nuclear decommissioning trusts: Stocks 2 1,765 — — — 1,765 Fixed Income 3 738 2,024 — — 2,762 Short-term investments, primarily cash equivalents 98 48 — — 146 Subtotal of nuclear decommissioning trusts 4 2,601 2,072 — — 4,673 Total assets 2,605 2,105 83 (15) 4,778 Liabilities at fair value Derivative contracts — 11 5 (15) 1 Total liabilities — 11 5 (15) 1 Net assets $ 2,605 $ 2,094 $ 78 $ — $ 4,777 1 Represents the netting of assets and liabilities under master netting agreements and cash collateral. 2 Approximately 71% and 72% of SCE's equity investments were located in the United States at December 31, 2020 and 2019, respectively. 3 Includes corporate bonds, which were diversified and included collateralized mortgage obligations and other asset backed securities of $29 million and $46 million at December 31, 2020 and 2019, respectively. 4 Excludes net payables of $206 million and $111 million at December 31, 2020 and 2019, respectively, which consist of interest and dividend receivables as well as receivables and payables related to SCE's pending securities sales and purchases. Edison International Parent and Other Edison International Parent and Other assets measured at fair value and classified as Level 1 consisted of money market funds of $24 million and $31 million at December 31, 2020 and 2019, respectively. Edison International Parent and Other assets measured at fair value and classified as Level 2 consisted of short-term investments of $5 million at December 31, 2020. Edison International Parent and Other had no short-term investments as of December 31, 2019. SCE Fair Value of Level 3 The following table sets forth a summary of changes in SCE's fair value of Level 3 net derivative assets and liabilities: December 31, (in millions) 2020 2019 Fair value of net assets at beginning of period $ 78 $ 141 Purchases 8 6 Sales (5) (5) Settlements (117) (60) Total realized/unrealized gains (losses) 1,2 144 (4) Fair value of net assets at end of period $ 108 $ 78 1 Due to regulatory mechanisms, SCE's realized and unrealized gains and losses are recorded as regulatory assets and liabilities. 2 There were no material transfers into or out of Level 3 during 2020 and 2019. The following table sets forth SCE's valuation techniques and significant unobservable inputs used to determine fair value for significant Level 3 assets and liabilities: Fair Value (in millions) Significant Range (per MWh) Weighted Average (per MWh) Assets Liabilities Valuation Technique Unobservable Input Congestion revenue rights December 31, 2020 $ 120 $ 12 Auction prices CAISO CRR auction clearing prices $(9.67) - $300.47 $2.75 December 31, 2019 83 5 Auction prices CAISO CRR auction clearing prices (3.59) - 25.32 1.97 Level 3 Fair Value Uncertainty For CRRs, increases or decreases in CAISO auction price would result in higher or lower fair value, respectively. Nuclear Decommissioning Trusts SCE's nuclear decommissioning trust investments include equity securities, U.S. treasury securities and other fixed income securities. Equity and treasury securities are classified as Level 1 as fair value is determined by observable market prices in active or highly liquid and transparent markets. The remaining fixed income securities are classified as Level 2. The fair value of these financial instruments is based on evaluated prices that reflect significant observable market information such as reported trades, actual trade information of similar securities, benchmark yields, broker/dealer quotes, issuer spreads, bids, offers and relevant credit information. There are no securities classified as Level 3 in the nuclear decommissioning trusts. SCE's investment policies and CPUC requirements place limitations on the types and investment grade ratings of the securities that may be held by the nuclear decommissioning trust funds. These policies restrict the trust funds from holding alternative investments and limit the trust funds' exposures to investments in highly illiquid markets. With respect to equity and fixed income securities, the trustee obtains prices from third-party pricing services which SCE is able to independently corroborate as described below. The trustee monitors prices supplied by pricing services, including reviewing prices against defined parameters' tolerances and performs research and resolves variances beyond the set parameters. SCE corroborates the fair values of securities by comparison to other market-based price sources obtained by SCE's investment managers. Differences outside established thresholds are followed-up with the trustee and resolved. For each reporting period, SCE reviews the trustee determined fair value hierarchy and overrides the trustee level classification when appropriate. Nonrecurring Fair Value Measurements Edison International assesses goodwill at the reporting unit level. The fair value of the Edison Energy reporting unit is classified as Level 3 and is estimated using the income approach. During the second quarter of 2020 and fourth quarter of 2019, Edison International evaluated the recoverability of goodwill and recorded impairment charges of Edison Energy's goodwill totaling $34 million ($25 million after-tax) and $25 million ($18 million after-tax), respectively. See Note 1 for further details. Fair Value of Debt Recorded at Carrying Value The carrying value and fair value of Edison International's and SCE's long-term debt (including current portion of long-term debt) are as follows: December 31, 2020 December 31, 2019 (in millions) Carrying Value 1 Fair Value 2 Carrying Value 1 Fair Value 2 Edison International $ 20,337 $ 23,824 $ 18,343 $ 20,137 SCE 17,204 20,365 15,211 16,892 1 Carrying value is net of debt issuance costs. 2 The fair value of Edison International's and SCE's long-term debt is classified as Level 2. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments | Derivative Instruments Derivative financial instruments are used to manage exposure to commodity price risk. These risks are managed in part by entering into forward commodity transactions, including options, swaps and futures. To mitigate credit risk from counterparties in the event of nonperformance, master netting agreements are used whenever possible and counterparties may be required to pledge collateral depending on the creditworthiness of each counterparty and the risk associated with the transaction. Commodity Price Risk Commodity price risk represents the potential impact that can be caused by a change in the market value of a particular commodity. SCE's electricity price exposure arises from energy purchased from and sold to wholesale markets as a result of differences between SCE's load requirements and the amount of energy delivered from its generating facilities and PPAs. SCE's natural gas price exposure arises from natural gas purchased for the Mountainview power plant and peaker plants, qualifying facilities contracts where pricing is based on a monthly natural gas index and PPAs in which SCE has agreed to provide the natural gas needed for generation, referred to as tolling arrangements. Credit and Default Risk Credit and default risk represent the potential impact that can be caused if a counterparty were to default on its contractual obligations and SCE would be exposed to spot markets for buying replacement power or selling excess power. In addition, SCE would be exposed to the risk of non-payment of accounts receivable, primarily related to the sales of excess power and realized gains on derivative instruments. Certain power and gas contracts contain master netting agreements or similar agreements, which generally allow counterparties subject to the agreement to offset amounts when certain criteria are met, such as in the event of default. The objective of netting is to reduce credit exposure. Additionally, to reduce SCE's risk exposures counterparties may be required to pledge collateral depending on the creditworthiness of each counterparty and the risk associated with the transaction. Certain power and gas contracts contain a provision that requires SCE to maintain an investment grade rating from each of the major credit rating agencies, referred to as a credit-risk-related contingent feature. If SCE's credit rating were to fall below investment grade, SCE may be required to post additional collateral to cover derivative liabilities and the related outstanding payables. The net fair value of all derivative liabilities with these credit-risk-related contingent features was less than $1 million and $1 million as of December 31, 2020 and 2019, respectively, for which SCE has posted no collateral to its counterparties at the respective dates for its derivative liabilities and related outstanding payables for both periods. If the credit-risk-related contingent features underlying these agreements were triggered on December 31, 2020, SCE would be required to post $3 million of additional collateral, all of which is related to outstanding payables. Fair Value of Derivative Instruments SCE presents its derivative assets and liabilities on a net basis on its consolidated balance sheets when subject to master netting agreements or similar agreements. Derivative positions are also offset against margin and cash collateral deposits. In addition, SCE has provided collateral in the form of letters of credit. Collateral requirements can vary depending upon the level of unsecured credit extended by counterparties, changes in market prices relative to contractual commitments and other factors. See Note 4 for a discussion of fair value of derivative instruments. The following table summarizes the gross and net fair values of SCE's commodity derivative instruments: December 31, 2020 Derivative Assets Derivative Liabilities Net Asset (in millions) Short-Term 1 Long-Term 2 Subtotal Short-Term 3 Long-Term Subtotal Commodity derivative contracts Gross amounts recognized $ 103 $ 23 $ 126 $ 16 $ 6 $ 22 $ 104 Gross amounts offset in the consolidated balance sheets (12) (6) (18) (12) (6) (18) — Cash collateral posted 4 — — — (4) — (4) 4 Net amounts presented in the consolidated balance sheets $ 91 $ 17 $ 108 $ — $ — $ — $ 108 December 31, 2019 Derivative Assets Derivative Liabilities Net Asset (in millions) Short-Term 1 Long-Term 2 Subtotal Short-Term 3 Long-Term Subtotal Commodity derivative contracts Gross amounts recognized $ 94 $ 8 $ 102 $ 14 $ 2 $ 16 $ 86 Gross amounts offset in the consolidated balance sheets (13) (2) (15) (13) (2) (15) — Cash collateral posted 4 — — — — — — — Net amounts presented in the consolidated balance sheets $ 81 $ 6 $ 87 $ 1 $ — $ 1 $ 86 1 Included in "Other current assets" on Edison International's and SCE's consolidated balance sheets. 2 Included in "Other long-term assets" on Edison International's and SCE's consolidated balance sheets. 3 Included in "Other current liabilities" on Edison International's and SCE's consolidated balance sheets. 4 At December 31, 2020, SCE posted $17 million of cash, of which $4 million was offset against derivative liabilities and $13 million was reflected in "Other current assets" on the consolidated balance sheets. At December 31, 2019, SCE posted $24 million of cash, all of which was not offset against net derivative liabilities and was reflected in "Other current assets" on the consolidated balance sheets. Financial Statement Impact of Derivative Instruments SCE recognizes realized gains and losses on derivative instruments as purchased power expense and expects that such gains or losses will be part of the purchased power costs recovered from customers. As a result, realized gains and losses do not affect earnings, but may temporarily affect cash flows. Due to expected future recovery from customers, unrealized gains and losses are recorded as regulatory assets and liabilities and therefore also do not affect earnings. The remaining effects of derivative activities and related regulatory offsets are reported in cash flows from operating activities in the consolidated statements of cash flows. The following table summarizes the components of SCE's economic hedging activity: Years ended December 31, (in millions) 2020 2019 2018 Realized gains (losses) $ 87 $ (7) $ 26 Unrealized gains (losses) 17 (74) 82 Notional Volumes of Derivative Instruments The following table summarizes the notional volumes of derivatives used for SCE economic hedging activities: Economic Hedges Unit of December 31, Commodity Measure 2020 2019 Electricity options, swaps and forwards GWh 1,581 3,155 Natural gas options, swaps and forwards Bcf 34 43 Congestion revenue rights GWh 41,151 48,170 |

Revenue from Contract with Customer [Abstract] | |
Revenue | Revenue • Earning activities – representing revenue authorized by the CPUC and FERC, which is intended to provide SCE a reasonable opportunity to recover its costs and earn a return on its net investment in generation, transmission and distribution assets. The annual revenue requirements are comprised of authorized operation and maintenance costs, depreciation, taxes and a return consistent with the capital structure. Also, included in earnings activities are revenues or penalties related to incentive mechanisms, other operating revenue and regulatory charges or disallowances. • Cost-recovery activities – representing CPUC- and FERC- authorized balancing accounts, which allow for recovery of specific project or program costs, subject to reasonableness review or compliance with upfront standards. Cost-recovery activities include rates which provide recovery, subject to reasonableness review of, among other things, fuel costs, purchased power costs, public purpose related-program costs (including energy efficiency and demand-side management programs) and certain operation and maintenance expenses. SCE earns no return on these activities. The following table is a summary of SCE's revenue: Years ended December 31, 2020 2019 2018 (in millions) Earning Activities Cost- Recovery Activities Total Consolidated Earning Activities Cost- Recovery Activities Total Consolidated Earning Activities Cost-Recovery Activities Total Consolidated Revenues from contracts with customers 1,2 $ 6,920 $ 5,539 $ 12,459 $ 6,512 $ 4,655 $ 11,167 $ 6,519 $ 5,611 $ 12,130 Alternative revenue programs and other operating revenue 3 548 539 1,087 166 973 1,139 41 440 481 Total operating revenue $ 7,468 $ 6,078 $ 13,546 $ 6,678 $ 5,628 $ 12,306 $ 6,560 $ 6,051 $ 12,611 1 In the absence of a 2018 GRC decision, SCE recognized CPUC revenue in 2018 and first quarter of 2019 based on the 2017 authorized revenue requirements adjusted mainly for the July 2017 cost of capital decision and Tax Reform. SCE recorded the impact of the 2018 GRC final decision in the second quarter of 2019, including a $289 million reduction in revenue related to 2018. These revenue adjustments are included in "Revenues from contracts with customers." See "Note 1. Summary of Significant Accounting Policies—Revenue Recognition—Regulatory Proceedings—2018 General Rate Case" for further information. 2 At December 31, 2020 and 2019, SCE's receivables related to contracts from customers were $1.5 billion and $1.1 billion, which included accrued unbilled revenue of $521 million and $488 million, respectively. 3 Includes differences between amounts billed and authorized levels for both the CPUC and FERC. |

For further information, see Note 12 and Note 1. 2 As of December 31, 2020, deferred tax assets for net operating loss and tax credit carryforwards are reduced by unrecognized tax benefits of $270 million and $190 million for Edison International and SCE, respectively. 3 As of December 31, 2020, Edison International has recorded a valuation allowance of $31 million for non-California state net operating loss carryforwards, and $4 million for California capital losses generated from sale of SoCore Energy in 2018, which are estimated to expire before being utilized. 4 Included in "Deferred income taxes and credits" on the consolidated balance sheets. Net Operating Loss and Tax Credit Carryforwards The amounts of net operating loss and tax credit carryforwards (after-tax) are as follows: Edison International SCE December 31, 2020 (in millions) Loss Carryforwards Credit Carryforwards Loss Carryforwards Credit Carryforwards Expire in 2021 $ 4 $ — $ 4 $ — Expire between 2022 to 2025 31 — 26 — Expire between 2029 to 2042 1,192 515 380 50 No expiration date 1 509 10 413 — Total $ 1,736 $ 525 $ 823 $ 50 1 Under Tax Reform, federal net operating losses generated after December 31, 2017 can carryforward indefinitely. Edison International consolidates for federal income tax purposes, but not for financial accounting purposes, a group of wind projects referred to as Capistrano Wind. The amount of net operating loss and tax credit carryforwards recognized as part of deferred income taxes includes $218 million and $212 million related to Capistrano Wind for 2020 and 2019, respectively. Under a tax allocation agreement, Edison International has recorded a corresponding liability as part of other long-term liabilities related to its obligation to make payments to Capistrano Wind of these tax benefits when realized. Effective Tax Rate The table below provides a reconciliation of income tax expense computed at the federal statutory income tax rate to the income tax provision: Edison International SCE Years ended December 31, (in millions) 2020 2019 2018 2020 2019 2018 Income (loss) from continuing operations before income taxes $ 566 $ 1,127 $ (1,089) $ 665 $ 1,301 $ (885) Provision for income tax at federal statutory rate of 21% 119 237 (229) 140 273 (186) Increase in income tax from: Items presented with related state income tax, net: State tax, net of federal benefit (61) (22) (168) (52) (13) (155) Property-related (320) (303) (275) (320) (303) (275) Change related to uncertain tax positions 1 (15) — (66) (19) — (71) Deferred tax re-measurement 2 — (88) — — (88) — 2018 GRC Final Decision — (80) — — (80) — Corporate-owned life insurance cash surrender value (8) (8) (8) (8) (8) (8) Other (20) (14) 7 (18) (10) (1) Total income tax benefit from continuing operations $ (305) $ (278) $ (739) $ (277) $ (229) $ (696) Effective tax rate (53.9) % (24.7) % (67.9) % (41.7) % (17.6) % (78.6) % 1 In 2020, Edison International and SCE recognized tax expense and benefit, respectively, primarily due to the re-measurement of uncertain tax positions related to the 2010 – 2012 California state tax filings currently under audit. In 2018, Edison International and SCE recognized tax benefits related to a settlement with the California Franchise Tax Board for tax years 1994 – 2006. See further discussion in Tax Disputes below. 2 Relates to changes in the allocation of deferred tax re-measurement between customers and shareholders as a result of a CPUC resolution issued in February 2019. The resolution determined that customers are only entitled to excess deferred taxes which were included when setting rates, while other deferred tax re-measurement belongs to the shareholders. The CPUC requires flow-through ratemaking treatment for the current tax benefit arising from certain property-related and other temporary differences which reverse over time. Flow-through items reduce current authorized revenue requirements in SCE's rate cases and result in a regulatory asset for recovery of deferred income taxes in future periods. The difference between the authorized amounts as determined in SCE's rate cases, adjusted for balancing and memorandum account activities, and the recorded flow-through items also result in increases or decreases in regulatory assets with a corresponding impact on the effective tax rate to the extent that recorded deferred amounts are expected to be recovered in future rates. For further information, see Note 11. Accounting for Uncertainty in Income Taxes Authoritative guidance related to accounting for uncertainty in income taxes requires an enterprise to recognize, in its financial statements, the best estimate of the impact of a tax position by determining if the weight of available evidence indicates it is more likely than not, based solely on the technical merits, that the position will be sustained upon examination. The guidance requires the disclosure of all unrecognized tax benefits, which includes both the reserves recorded for tax positions on filed tax returns and the unrecognized portion of affirmative claims. Unrecognized Tax Benefits The following table provides a reconciliation of unrecognized tax benefits for continuing and discontinued operations: Edison International SCE December 31, (in millions) 2020 2019 2018 2020 2019 2018 Balance at January 1, $ 370 $ 338 $ 432 $ 282 $ 249 $ 331 Tax positions taken during the current year: Increases 55 46 41 56 47 42 Tax positions taken during a prior year: Increases 1 274 6 — 4 6 — Decreases 2 (20) (20) (108) (22) (20) (121) Settlements with taxing authorities 3 — — (27) — — (3) Balance at December 31, $ 679 $ 370 $ 338 $ 320 $ 282 $ 249 1 Edison International recorded favorable tax positions in 2020 in connection with the Edison Mission Energy ("EME") bankruptcy that required a revaluation of the reserve for uncertain tax positions. 2 Decrease in 2018 was related to re-measurement as a result of a settlement with the California Franchise Tax Board for tax years 1994 – 2006. 3 In 2018, Edison International reached a settlement with the California Franchise Tax Board for tax years 1994 – 2006. As of December 31, 2020, if recognized, $446 million of unrecognized tax benefits would impact Edison International's effective tax rate and $87 million of the unrecognized tax benefits would impact SCE's effective tax rate. Tax Disputes Tax years that remain open for examination by the IRS and the California Franchise Tax Board are 2016 – 2019 and 2013 – 2019, respectively. Tax years 2007 – 2012 are currently subject to a settlement proceeding with the California Franchise Tax Board. Edison International does not expect to resolve these tax years within the next 12 months. Any impacts cannot be reasonably estimated until further progress is made. In the fourth quarter of 2018, Edison International recorded the impacts of a settlement reached with the California Franchise Tax Board for tax years 1994 – 2006 that resulted in a $65 million refund of tax and interest. This refund was received in the second quarter of 2019. Accrued Interest and Penalties The total amount of accrued interest and penalties related to income tax liabilities for continuing and discontinued operations are: Edison International SCE Years ended December 31, (in millions) 2020 2019 2020 2019 Accrued interest and penalties $ 52 $ 56 $ 23 $ 29 The net after-tax interest and penalties recognized in income tax expense (benefit) for continuing and discontinued operations are: Edison International SCE December 31, (in millions) 2020 2019 2018 2020 2019 2018 Net after-tax interest and penalties tax expense (benefit) $ 4 $ 4 $ (62) $ 6 $ 3 $ (25) |

Retirement Benefits [Abstract] | |
Compensation and Benefit Plans | Compensation and Benefit Plans Employee Savings Plan The 401(k) defined contribution savings plan is designed to supplement employees' retirement income. The employer contributions were as follows: Edison International SCE (in millions) Years ended December 31, 2020 $ 93 $ 92 2019 82 81 2018 74 74 Pension Plans and Postretirement Benefits Other Than Pensions Pension Plans Noncontributory defined benefit pension plans (some with cash balance features) cover most employees meeting minimum service requirements. Employees hired by the Participating Companies on or after December 31, 2017 will no longer be eligible to participate in the Plan. In lieu of that, an additional non-contributory employer contribution will be deposited into the Edison 401(k) Savings Plan. SCE recognizes pension expense for its nonexecutive plan as calculated by the actuarial method used for ratemaking. The expected contributions (all by the employer) for Edison International and SCE are approximately $55 million and $31 million, respectively, for the year ending December 31, 2021. Annual contributions made by SCE to most of SCE's pension plans are anticipated to be recovered through CPUC-approved regulatory mechanisms. The funded position of Edison International's pension is sensitive to changes in market conditions. Changes in overall interest rate levels significantly affect the company's liabilities, while assets held in the various trusts established to fund Edison International's pension are affected by movements in the equity and bond markets. Due to SCE's regulatory recovery treatment, a regulatory asset has been recorded equal to the unfunded status. See Note 11 for further information. Information on pension plan assets and benefit obligations for continuing and discontinued operations is shown below.

SCE's accumulated other comprehensive loss of $16 million and $17 million at December 31, 2020 and 2019, excludes net losses of $41 million and $37 million related to these benefits, respectively. For Edison International and SCE, respectively, the 2020 actuarial losses are primarily related to $339 million and $305 million in losses from a decrease in the discount rate (from 3.11% as of December 31, 2019 to 2.38% as of December 31, 2020), partially offset by $117 million and $124 million in gains from other economic assumption changes; the 2019 actuarial losses are primarily related to $401 million and $373 million in losses from a decrease in the discount rate (from 4.19% as of December 31, 2018 to 3.11% as of December 31, 2019), partially offset by $157 million and $177 million in gains from other economic assumption changes.

Edison International and SCE used the following weighted average assumptions to determine pension expense for continuing operations: Years ended December 31, 2020 2019 2018 Discount rate 3.11 % 4.19 % 3.46 % Rate of compensation increase 4.10 % 4.10 % 4.10 % Expected long-term return on plan assets 6.00 % 6.50 % 6.50 % Interest crediting rate for cash balance account Starting rate 3.61 % 4.46 % 4.36 % Ultimate rate 5.00 % 5.75 % 5.75 % Year ultimate rate is reached 2025 2022 2022 The following benefit payments, which reflect expected future service, are expected to be paid: (in millions) Edison International SCE 2021 $ 294 $ 254 2022 297 259 2023 298 262 2024 299 266 2025 302 268 2026 – 2030 1,403 1,317 Postretirement Benefits Other Than Pensions ("PBOP(s)") Employees hired prior to December 31, 2017 who are retiring at or after age 55 with at least 10 years of service may be eligible for postretirement healthcare benefits. Eligibility for a company contribution toward the cost of these benefits in retirement depends on a number of factors, including the employee's years of service, age, hire date, and retirement date. Employees hired on or after December 31, 2017 are no longer eligible for retiree healthcare benefits. In lieu of those benefits, the Company will provide a health reimbursement account of $200 per month available only after meeting certain age and service year requirements. Under the terms of the Edison International Welfare Benefit Plan ("PBOP Plan"), each participating employer (Edison International or its participating subsidiaries) is responsible for the costs and expenses of all PBOP Plan benefits with respect to its employees and former employees that exceed the participants' share of contributions. A participating employer may terminate the PBOP Plan benefits with respect to its employees and former employees, as may SCE (as PBOP Plan sponsor), and, accordingly, the participants' PBOP Plan benefits are not vested benefits. The expected contributions (substantially all of which are expected to be made by SCE) for PBOP benefits are $9 million for the year ended December 31, 2021. Annual contributions related to SCE employees made to SCE plans are anticipated to be recovered through CPUC-approved regulatory mechanisms and are expected to be, at a minimum, equal to the total annual expense for these plans. SCE has three voluntary employees' beneficiary association trusts ("VEBA Trusts") that can only be used to pay for retiree health care benefits of SCE and its subsidiaries. Once funded into the VEBA Trusts, neither SCE nor Edison International can subsequently recover remaining amounts in the VEBA Trusts. Participants of the PBOP Plan do not have a beneficial interest in the VEBA Trusts. The VEBA Trust assets are sensitive to changes in market conditions. Changes in overall interest rate levels significantly affect the company's liabilities, while assets held in the various trusts established to fund Edison International's other postretirement benefits are affected by movements in the equity and bond markets. Due to SCE's regulatory recovery treatment, the unfunded status is offset by a regulatory asset.

Plan assets are invested using a combination of asset classes and may have active and passive investment strategies within asset classes. Target allocations for 2020 pension plan assets were 23% for U.S. equities, 17% for non-U.S. equities, 45% for fixed income and 15% for opportunistic and/or alternative investments. Target allocations for 2020 PBOP plan assets (except for Represented VEBA which is 95% for fixed income and 5% for U.S. and non-U.S. equities) are 58% for U.S. and non-U.S. equities, 29% for fixed income and 13% for opportunistic and/or alternative investments. Edison International employs multiple investment management firms. Investment managers within each asset class cover a range of investment styles and approaches. Risk is managed through diversification among multiple asset classes, managers, styles and securities. Plan asset classes and individual manager performances are measured against targets. Edison International also monitors the stability of its investment managers' organizations. Allowable investment types include: • United States equities: common and preferred stocks of large, medium, and small companies which are predominantly United States-based. • Non-United States equities: equity securities issued by companies domiciled outside the United States and in depository receipts which represent ownership of securities of non-United States companies. • Fixed income: fixed income securities issued or guaranteed by the United States government, non-United States governments, government agencies and instrumentalities including municipal bonds, mortgage backed securities and corporate debt obligations. A portion of the fixed income positions may be held in debt securities that are below investment grade. • Opportunistic, alternative and other investments: Opportunistic investments in short to intermediate term market opportunities. Investments may have fixed income and/or equity characteristics and may be either liquid or illiquid. Alternative investments are limited partnerships that invest in non-publicly traded entities. Other investments are diversified among multiple asset classes such as global equity, fixed income currency and commodities markets. Investments are made in liquid instruments within and across markets. The investment returns are expected to approximate the plans' expected investment returns. Asset class portfolio weights are permitted to range within plus or minus 3%. Where approved by the fiduciary investment committee, futures contracts are used for portfolio rebalancing and to reallocate portfolio cash positions. Where authorized, a few of the plans' investment managers employ limited use of derivatives, including futures contracts, options, options on futures and interest rate swaps in place of direct investment in securities to gain efficient exposure to markets. Derivatives are not used to leverage the plans or any portfolios. Determination of the Expected Long-Term Rate of Return on Assets The overall expected long-term rate of return on assets assumption is based on the long-term target asset allocation for plan assets and capital markets return forecasts for asset classes employed. A portion of the PBOP trust asset returns are subject to taxation, so the expected long-term rate of return for these assets is determined on an after-tax basis. Capital Markets Return Forecasts SCE's capital markets return forecast methodologies primarily use a combination of historical market data, current market conditions, proprietary forecasting expertise, complex models to develop asset class return forecasts and a building block approach. The forecasts are developed using variables such as real risk-free interest, inflation and asset class specific risk premiums. For equities, the risk premium is based on an assumed average equity risk premium of 5% over cash. The forecasted return on private equity and opportunistic investments are estimated at a 4% premium above public equity, reflecting a premium for higher volatility and lower liquidity. For fixed income, the risk premium is based on a comprehensive modeling of credit spreads. Fair Value of Plan Assets The PBOP Plan and the Southern California Edison Company Retirement Plan Trust ("Master Trust") assets include investments in equity securities, U.S. treasury securities, other fixed-income securities, common/collective funds, mutual funds, other investment entities, foreign exchange and interest rate contracts, and partnership/joint ventures. Equity securities, U.S. treasury securities, mutual and money market funds are classified as Level 1 as fair value is determined by observable, unadjusted quoted market prices in active or highly liquid and transparent markets. The fair value of the underlying investments in equity mutual funds are based on stock-exchange prices. The fair value of the underlying investments in fixed-income mutual funds and other fixed income securities including municipal bonds are based on evaluated prices that reflect significant observable market information such as reported trades, actual trade information of similar securities, benchmark yields, broker/dealer quotes, issuer spreads, bids, offers and relevant credit information. Foreign exchange and interest rate contracts are classified as Level 2 because the values are based on observable prices but are not traded on an exchange. Futures contracts trade on an exchange and therefore are classified as Level 1. No investment is classified as Level 3 as of December 31, 2020 and 2019. Common/collective funds and partnerships are measured at fair value using the net asset value per share ("NAV") and have not been classified in the fair value hierarchy. Other investment entities are valued similarly to common/collective funds and are therefore classified as NAV. The Level 1 registered investment companies are either mutual or money market funds. The remaining funds in this category are readily redeemable and classified as NAV and are discussed further at Note 9 to the pension plan master trust investments table below. Edison International reviews the process/procedures of both the pricing services and the trustee to gain an understanding of the inputs/assumptions and valuation techniques used to price each asset type/class. The trustee and Edison International's validation procedures for pension and PBOP equity and fixed income securities are the same as the nuclear decommissioning trusts. For further discussion, see Note 4. The values of Level 1 mutual and money market funds are publicly quoted. The trustees obtain the values of common/collective and other investment funds from the fund managers. The values of partnerships are based on partnership valuation statements updated for cash flows. SCE's investment managers corroborate the trustee fair values.

Stock-Based Compensation Edison International maintains a shareholder-approved incentive plan (the "2007 Performance Incentive Plan") that includes stock-based compensation. The maximum number of shares of Edison International's common stock authorized to be issued or transferred pursuant to awards under the 2007 Performance Incentive Plan, as amended, is approximately 71 million shares. As of December 31, 2020, Edison International had approximately 23 million shares remaining available for new award grants under its stock-based compensation plans. The following table summarizes total expense and tax benefits associated with stock-based compensation: Edison International SCE Years ended December 31, (in millions) 2020 2019 2018 2020 2019 2018 Stock-based compensation expense 1 : Stock options $ 15 $ 13 $ 11 $ 7 $ 7 $ 6 Performance shares 5 8 1 2 4 1 Restricted stock units 8 6 7 4 3 4 Other 1 2 2 — — — Total stock-based compensation expense 29 29 21 13 14 11 Income tax benefits related to stock compensation expense $ 4 $ 10 $ 6 $ 3 $ 6 $ 3 1 Reflected in "Operation and maintenance" on Edison International's and SCE's consolidated statements of income. Stock Options Under the 2007 Performance Incentive Plan, Edison International has granted stock options at exercise prices equal to the closing price at the grant date. Edison International may grant stock options and other awards related to, or with a value derived from, its common stock to directors and certain employees. Options generally expire 10 years after the grant date and vest over a period of four years of continuous service in equal annual increments, except for awards granted to retirement-eligible participants, which vest on an accelerated basis. The fair value for each option granted was determined as of the grant date using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires various assumptions noted in the following table: Years ended December 31, 2020 2019 2018 Expected terms (in years) 5.2 5.5 5.7 Risk-free interest rate 0.4% - 0.6% 1.6% - 2.3% 2.6% - 3.0% Expected dividend yield 4.2% - 5.0% 3.3% - 4.0% 3.6% - 4.3% Weighted average expected dividend yield 4.7% 3.9% 3.8% Expected volatility 24.9% - 26.9% 21.7% -24.1% 20.9% - 21.9% Weighted average volatility 25.0% 21.8% 20.9% The expected term represents the period of time for which the options are expected to be outstanding and is primarily based on historical exercise and post-vesting cancellation experience and stock price history. The risk-free interest rate for periods within the contractual life of the option is based on a zero-coupon U.S. Treasury STRIPS (separate trading of registered interest and principal of securities) whose maturity corresponds to the option's expected term on the measurement date. Expected volatility is based on the historical volatility of Edison International's common stock for the length of the option's expected term for 2020. The volatility period used was 63 months, 66 months and 68 months at December 31, 2020, 2019 and 2018, respectively. The following is a summary of the status of Edison International's stock options: Weighted Average Stock Options Exercise Remaining Aggregate Edison International: Outstanding at December 31, 2019 9,278,677 $ 62.27 Granted 1,993,954 68.60 Forfeited or expired (203,340) 65.75 Exercised 1 (359,908) 48.59 Outstanding at December 31, 2020 10,709,383 63.85 6.03 Vested and expected to vest at December 31, 2020 10,391,796 63.60 6.17 $ 30 Exercisable at December 31, 2020 6,489,876 $ 62.08 4.83 $ 27 SCE: Outstanding at December 31, 2019 4,934,702 $ 61.01 Granted 1,053,923 68.27 Forfeited or expired (189,691) 65.75 Exercised 1 (302,911) 49.49 Affiliate transfers, net (5,535) 63.36 Outstanding at December 31, 2020 5,490,488 62.85 5.86 Vested and expected to vest at December 31, 2020 5,325,052 62.50 5.98 $ 20 Exercisable at December 31, 2020 3,361,238 $ 60.41 4.56 $ 19 1 Edison International and SCE recognized tax benefits of $2 million and $2 million, respectively, from stock options exercised in 2020. At December 31, 2020, total unrecognized compensation cost related to stock options and the weighted average period the cost is expected to be recognized are as follows: Edison International SCE Unrecognized compensation cost, net of expected forfeitures (in millions) $ 17 $ 9 Weighted average period (in years) 2.3 2.3 Supplemental Data on Stock Options Edison International SCE Years ended December 31, (in millions, except per award amounts) 2020 2019 2018 2020 2019 2018 Stock options: Weighted average grant date fair value per option granted $ 8.18 $ 8.80 $ 8.21 $ 8.16 $ 8.83 $ 8.22 Fair value of options vested 2 14 14 2 7 7 Value of options exercised 9 27 10 7 19 7 Performance Shares A target number of contingent performance shares were awarded to executives in March 2020, 2019 and 2018 and vest at December 31, 2022, 2021 and 2020, respectively. The vesting of the grants is dependent upon market and financial performance and service conditions as defined in the grants for each of the years. The number of performance shares earned from each year's grants could range from zero to twice the target number (plus additional units credited as dividend equivalents). The fair value of market condition performance shares is determined using a Monte Carlo simulation valuation model for the total shareholder return.

Trust fund earnings (based on specific identification) increase the trust fund balance and the ARO regulatory liability. Unrealized holding gains, net of losses, were $2.1 billion and $1.8 billion at December 31, 2020 and 2019, respectively. Trust assets are used to pay income taxes. Deferred tax liabilities related to net unrealized gains were $515 million and $449 million at December 31, 2020 and December 31, 2019, respectively. Accordingly, the fair value of trust assets available to pay future decommissioning costs, net of deferred income taxes, totaled $4.3 billion and $4.1 billion at December 31, 2020 and December 31, 2019, respectively.

Regulatory Assets and Liabilities Disclosure [Abstract] | |
Regulatory Assets and Liabilities | Regulatory Assets and Liabilities Included in SCE's regulatory assets and liabilities are regulatory balancing accounts. CPUC-authorized balancing account mechanisms require SCE to refund or recover any differences between forecasted and actual costs. The CPUC has authorized balancing accounts for specified costs or programs such as fuel, purchased power, demand-side management programs, nuclear decommissioning and public purpose programs. Certain of these balancing accounts include a return on rate base of 7.68% and 7.61% in 2020 and 2019, respectively. The CPUC authorizes the use of a balancing account to recover from or refund to customers differences in revenue resulting from actual and forecasted electricity sales. Amounts included in regulatory assets and liabilities are generally recorded with corresponding offsets to the applicable income statement accounts. Regulatory Assets SCE's regulatory assets included on the consolidated balance sheets are: December 31, (in millions) 2020 2019 Current: Regulatory balancing and memorandum accounts $ 1,127 $ 798 Power contracts 165 189 Other 22 22 Total current 1,314 1,009 Long-term: Deferred income taxes, net of liabilities 4,475 4,026 Pension and other postretirement benefits 12 87 Power contracts 239 434 Unamortized investments, net of accumulated amortization 1 114 119 Unamortized loss on reacquired debt 133 142 Regulatory balancing and memorandum accounts 1,794 981 Environmental remediation 247 237 Other 106 62 Total long-term 7,120 6,088 Total regulatory assets $ 8,434 $ 7,097 1 Relates to a regulatory asset that earns a rate of return. See below for further information. In accordance with the accounting standards applicable to rate-regulated enterprises, SCE defers costs as regulatory assets that are probable of future recovery from customers and has recorded regulatory assets for these incremental costs at December 31, 2020. While SCE believes such costs are probable of future recovery, there is no assurance that SCE will collect all amounts currently deferred as regulatory assets. SCE's regulatory assets related to power contracts primarily represent derivative contracts that were designated as normal purchases and normal sales contracts. The liabilities for these power contracts are amortized over the remaining contract terms, approximately 2 to 3 years. For further information, see Note 1. SCE's regulatory assets related to deferred income taxes represent tax benefits passed through to customers. The CPUC requires SCE to flow through certain deferred income tax benefits to customers by reducing electricity rates, thereby deferring recovery of such amounts to future periods. Based on current regulatory ratemaking and income tax laws, SCE expects to recover its regulatory assets related to deferred income taxes over the life of the assets that give rise to the accumulated deferred income taxes, approximately from 1 to 60 years. For further information, see Note 8. SCE has long-term unamortized investments which include nuclear assets related to Palo Verde and the beyond the meter program. Nuclear assets related to Palo Verde and the beyond the meter program are expected to be recovered by 2044 and 2027, respectively, and earned returns of 7.68% and 7.61% in 2020 and 2019, respectively. SCE's net regulatory asset related to its unamortized loss on reacquired debt will be recovered over the original amortization period of the reacquired debt over periods ranging from 10 to 40 years or the life of the new issuance if the debt is refunded or refinanced. SCE's regulatory assets related to environmental remediation represent a portion of the costs incurred at certain sites that SCE is allowed to recover through customer rates. See "Environmental Remediation" discussed in Note 12. Regulatory Liabilities SCE's regulatory liabilities included on the consolidated balance sheets are: December 31, (in millions) 2020 2019 Current: Regulatory balancing and memorandum accounts $ 471 $ 883 Energy derivatives 87 80 Other 11 9 Total current 569 972 Long-term: Costs of removal 2,595 2,674 Re-measurement of deferred taxes 2,283 2,424 Recoveries in excess of ARO liabilities 1,930 1,569 Regulatory balancing and memorandum accounts 1,062 1,261 Other postretirement benefits 671 416 Other 48 41 Total long-term 8,589 8,385 Total regulatory liabilities $ 9,158 $ 9,357 SCE's regulatory liabilities related to energy derivatives are primarily an offset to unrealized gains on derivatives. SCE's regulatory liabilities related to costs of removal represent differences between asset removal costs recorded in depreciation and amounts collected in rates for those costs. As a result of Tax Reform, SCE's deferred tax assets and liabilities were re-measured at December 31, 2017, resulting in the initial recording of regulatory liabilities. The amount was further adjusted for CPUC's final resolution in February 2019, which stated that customers are only entitled to re-measurement of deferred taxes that were included when setting rates (i.e. included in rate base), and that all other deferred tax re-measurements belong to shareholders. The regulatory liabilities are generally expected to be refunded to customers over the lives of the assets and liabilities that gave rise to the deferred taxes. SCE's regulatory liabilities related to recoveries in excess of ARO liabilities represents the cumulative differences between ARO expenses and amounts collected in rates primarily for the decommissioning of the SCE's nuclear generation facilities. Decommissioning costs recovered through rates are primarily placed in nuclear decommissioning trusts. This regulatory liability also represents the deferral of realized and unrealized gains and losses on the nuclear decommissioning trust investments. See Note 10 for further discussion. SCE's regulatory liabilities related to other postretirement benefits represent the overfunded net actuarial gain. This amount will be refunded through rates charged to customers. See "Pension Plans and Postretirement Benefits Other than Pensions" discussion in Note 9. Net Regulatory Balancing and Memorandum Accounts Balancing accounts track amounts that the CPUC or FERC have authorized for recovery. Balancing account over and under collections represent differences between cash collected in current rates for specified forecasted costs and such costs that are actually incurred. Undercollections are recorded as regulatory balancing account assets. Overcollections are recorded as regulatory balancing account liabilities. With some exceptions, SCE seeks to adjust rates on an annual basis or at other designated times to recover or refund the balances recorded in its balancing accounts. Memorandum accounts are authorized to track costs for potential future recovery. Regulatory balancing and memorandum accounts that SCE does not expect to collect or refund in the next 12 months are reflected in the long-term section of the consolidated balance sheets. Regulatory balancing and memorandum accounts that do not have the right of offset are presented gross in the consolidated balance sheets. Under and over collections in balancing accounts and amounts recorded in memorandum accounts typically accrue interest based on a three-month commercial paper rate published by the Federal Reserve. The following table summarizes the significant components of regulatory balancing and memorandum accounts included in the above tables of regulatory assets and liabilities: December 31, (in millions) 2020 2019 Asset (liability) Energy resource recovery account $ (89) $ (23) Portfolio allocation balancing account 497 537 New system generation balancing account (10) 85 Public purpose programs and energy efficiency programs (1,130) (1,244) Base revenue requirement balancing account 622 (328) Greenhouse gas auction revenue and low carbon fuel standard revenue (125) (196) FERC balancing accounts 12 (127) Wildfire and drought restoration accounts 1 361 120 Wildfire-related memorandum accounts 2 1,104 748 COVID-19-related memorandum accounts 3 176 — Other (30) 63 Asset (Liability) $ 1,388 $ (365) 1 The wildfire and drought restoration accounts regulatory assets represent restorative costs that are recorded in a Catastrophic Event Memorandum Account ("CEMA"). 2 The wildfire-related memorandum accounts regulatory assets represent wildfire-related costs that are probable of future recovery from customers, subject to a reasonableness review. The Fire Hazard Prevention Memorandum Account ("FHPMA") is used to track costs related to fire safety and to implement fire prevention corrective action measures in extreme and very high fire threat areas. The Wildfire Expense Memorandum Account ("WEMA") is used to track incremental wildfire insurance costs and uninsured wildfire-related financing, legal and claims costs. During 2019, the CPUC approved a Wildfire Mitigation Plan memorandum account to track costs incurred to implement SCE's Wildfire Mitigation Plan that are not currently reflected in SCE's revenue requirements, a Grid Safety and Resiliency Program Memorandum Account ("GSRPMA") to track the costs of SCE's GS&RP that are incremental to costs approved for recovery in SCE's 2018 GRC and a fire risk mitigation memorandum account to track costs related to the reduction of fire risk that are incremental to costs approved for recovery in SCE's 2018 GRC that are not tracked in any other wildfire-related memorandum account. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Power Purchase Agreements SCE entered into various agreements to purchase power, electric capacity and other energy products. At December 31, 2020, the undiscounted future expected minimum payments for the SCE PPAs (primarily related to renewable energy contracts), which were approved by the CPUC and met other critical contract provisions (including completion of major milestones for construction), were as follows: (in millions) Total 2021 $ 3,144 2022 3,066 2023 2,937 2024 2,349 2025 2,236 Thereafter 21,756 Total future commitments 1 $ 35,488 1 Certain power purchase agreements are treated as operating or finance leases. For further discussion, see Note 13. Includes lease contracts commencing in 2021, 2022 and 2023 with future short-term lease expense of $242 million in 2021 and long-term minimum lease payments of $866 million. Additionally, as of December 31, 2020, SCE has executed contracts (including capacity reduction contracts) that have not met the critical contract provisions that would increase contractual obligations by $29 million in 2021, $72 million in 2022, $93 million in 2023, $111 million in 2024, $111 million in 2025 and $1.2 billion thereafter, if all critical contract provisions are completed. Costs incurred for PPAs were $3.8 billion in 2020, $3.7 billion in 2019 and $3.8 billion in 2018, which include costs associated with contracts with terms of less than one year. Other Commitments The following summarizes the estimated minimum future commitments for SCE's other commitments: (in millions) 2021 2022 2023 2024 2025 Thereafter Total Other contractual obligations $ 46 $ 43 $ 43 $ 45 $ 37 $ 154 $ 368 Costs incurred for other commitments were $80 million in 2020, $110 million in 2019 and $124 million in 2018. Other commitments include fuel supply contracts for Palo Verde which require payment only if the fuel is made available for purchase. Also included are commitments related to maintaining reliability and expanding SCE's transmission and distribution system. The table above does not include asset retirement obligations, which are discussed in Note 1. Indemnities Edison International and SCE have various financial and performance guarantees and indemnity agreements which are issued in the normal course of business. Edison International and SCE have agreed to provide indemnifications through contracts entered into in the normal course of business. These are primarily indemnifications against adverse litigation outcomes in connection with underwriting agreements, indemnities for specified environmental liabilities and income taxes with respect to assets sold or other contractual arrangements. Edison International's and SCE's obligations under these agreements may or may not be limited in terms of time and/or amount, and in some instances Edison International and SCE may have recourse against third parties. Edison International and SCE have not recorded a liability related to these indemnities. The overall maximum amount of the obligations under these indemnifications cannot be reasonably estimated. Contingencies In addition to the matters disclosed in these Notes, Edison International and SCE are involved in other legal, tax and regulatory proceedings before various courts and governmental agencies regarding matters arising in the ordinary course of business. Edison International and SCE believe the outcome of each of these other proceedings will not materially affect its financial position, results of operations and cash flows. Southern California Wildfires and Mudslides Wildfires in SCE's territory, including those where SCE's equipment may be alleged to be associated with the fire's ignition, have caused loss of life and substantial damage in recent years. Multiple factors have contributed to increased wildfire activity and faster progression of wildfires across SCE's service territory and in other areas of California. These include the buildup of dry vegetation in areas severely impacted by years of historic drought, lack of adequate clearing of hazardous fuels by responsible parties, higher temperatures, lower humidity, increased incidence of dry lightning, and strong Santa Ana winds. At the same time that wildfire risk has been increasing in Southern California, residential and commercial development has occurred and is occurring in some of the highest-risk areas. Such factors can increase the likelihood and extent of wildfires. SCE has determined that approximately 27% of its service territory is in areas identified as high fire risk. California has experienced unprecedented weather conditions in recent years and SCE's service territory remains susceptible to additional wildfire activity in 2021 and beyond. The worsening conditions across California increase the likelihood of wildfires, including those where SCE's equipment may be alleged to be associated with the fire's ignition. In response to worsening weather and fuel conditions and increased wildfire activity over the past several years, SCE has developed and is implementing its 2020 – 2022 Wildfire Mitigation Plan ("WMP") to reduce the risk of SCE equipment contributing to the ignition of wildfires. In addition, California has increased its investment in wildfire suppression capabilities. In addition to the investments SCE is making through its WMP, SCE also uses its Public Safety Power Shutoffs ("PSPS") program to proactively de-energize power lines to mitigate the risk of catastrophic wildfires during extreme weather events. SCE initiated PSPS 12 times in 2020 as part of its wildfire mitigation efforts, impacting an aggregate of approximately 140,000 unique customers. In January 2021, the President of the CPUC sent SCE a letter expressing her concern regarding SCE's execution of PSPS in 2020 and notifying SCE that it must implement a PSPS action plan to reduce the impacts of PSPS on the customers and communities it serves. On a risk-informed basis, SCE is making efforts to reduce the frequency and impacts of PSPS in 2021 as compared to 2020, assuming that weather patterns in 2021 are similar to those experienced in 2020. SCE may be subject to mandated changes to, or restrictions on, its operational PSPS practices, regulatory fines and penalties, claims for damages and reputational harm if SCE does not execute PSPS in compliance with applicable rules and regulations or if it is determined that SCE has placed excessive reliance on PSPS. Edison International and SCE accrued estimated losses of $1,328 million in 2020 for wildfire-related claims, net of expected insurance recoveries. The 2020 charge includes an increase in estimated losses for claims related to the 2017/2018 Wildfire/Mudslide Events (defined below) of $1,297 million, against which SCE has recorded expected recoveries through FERC electric rates of $84 million. The resulting charge was $1,213 million ($874 million after-tax). The 2020 charge also includes $31 million ($21 million after FERC recovery and after-tax) of expenses primarily associated with self-insured retention related to the 2019/2020 Wildfires (defined below). Edison International and SCE have incurred material losses in connection with the 2017/2018 Wildfire/Mudslide Events, which are described below. Several wildfires have originated in Southern California subsequent to 2018, however, Edison International and SCE expect that any losses incurred in connection with these fires will be covered by insurance, subject to self-insured retentions and co-insurance, and expect that any such losses after insurance recoveries will not be material. Liability Overview The extent of liability for wildfire-related damages in actions against utilities depends on a number of factors, including whether the utility substantially caused or contributed to the damages and whether parties seeking recovery of damages will be required to show negligence in addition to causation. California courts have previously found utilities to be strictly liable for property damage along with associated interest and attorneys' fees, regardless of fault, by applying the theory of inverse condemnation when a utility's facilities were determined to be a substantial cause of a wildfire that caused the property damage. If inverse condemnation is held to be inapplicable to SCE in connection with a wildfire, SCE still could be held liable for property damages and associated interest if the property damages were found to have been proximately caused by SCE's negligence. If SCE were to be found negligent, SCE could also be held liable for, among other things, fire suppression costs, business interruption losses, evacuation costs, clean-up costs, medical expenses, and personal injury/wrongful death claims. Additionally, SCE could potentially be subject to fines for alleged violations of CPUC rules and state laws in connection with the ignition of a wildfire. Final determinations of liability for wildfire events, including determinations of whether SCE was negligent, would only be made during lengthy and complex litigation processes. Even when investigations are still pending or liability is disputed, an assessment of likely outcomes, including through future settlement of disputed claims, may require estimated losses to be accrued under accounting standards. Each reporting period, management reviews its loss estimates for remaining alleged and potential claims related to wildfire events. The process for estimating losses associated with alleged and potential wildfire-related claims requires management to exercise significant judgment based on a number of assumptions and subjective factors, including, but not limited to: estimates of known and expected claims by third parties based on currently available information, opinions of counsel regarding litigation risk, the status of and developments in the course of litigation, and prior experience litigating and settling wildfire litigation claims. As additional information becomes available, management's estimates and assumptions regarding the causes and financial impact of wildfire events may change. 2019/2020 Wildfires Several wildfires significantly impacted portions of SCE's service territory in 2019 and 2020 (the wildfires that originated in Southern California in 2019 and 2020 where SCE's equipment may be alleged to be associated with the fire's ignition are referred to collectively as the "2019/2020 Wildfires"). Edison International and SCE expect that any losses incurred in connection with the 2019/2020 Wildfires will be covered by insurance, subject to self-insured retentions and co-insurance, and expect that any such losses after insurance recoveries will not be material. As of December 31, 2020, Edison International and SCE had estimated losses (established at the lower end of the reasonably estimated range of expected losses) of $117 million reflected on their consolidated balance sheets related to the 2019/2020 Wildfires. As of the same date, Edison International and SCE also had assets for expected recoveries from insurance of $75 million and expected recoveries from FERC of $3 million on their consolidated balance sheets related to the 2019/2020 Wildfires. One of the 2019/2020 Wildfires, the "Saddle Ridge" Fire, originated in Los Angeles county in October 2019 and burned approximately 9,000 acres, destroyed an estimated 19 structures, damaged an estimated 88 structures, and resulted in injuries to 8 individuals and one fatality. An investigation into the cause of the Saddle Ridge Fire is being led by the Los Angeles Fire Department. Based on pending litigation and without considering insurance recoveries, it is reasonably possible that SCE will incur a material loss in connection with the Saddle Ridge Fire, but the range of possible losses that could be incurred cannot be estimated at this time. SCE has not accrued a charge for potential losses relating to the Saddle Ridge Fire. Another of the 2019/2020 Wildfires, the "Bobcat Fire" was reported in the vicinity of Cogswell Dam in Los Angeles County, California in September 2020. The United States Forest Service ("USFS") has reported that the Bobcat Fire burned approximately 116,000 acres in Los Angeles County, destroyed an estimated 87 homes, 1 commercial property and 83 minor structures, damaged an estimated 28 homes and 19 minor structures, and resulted in injuries to 6 firefighters. In addition, the USFS has estimated suppression costs at $80 million. A camera in the vicinity of Cogswell Dam captured the initial stages of a fire with the first observed smoke approximately six minutes before an SCE circuit in the area experienced an anomaly (a relay). An investigation into the cause of the Bobcat Fire is being led by the USFS, and the USFS has taken a specific section of an SCE overhead conductor in the vicinity of Cogswell Dam into possession as part of its investigation. SCE understands that the USFS has also taken three tree branches in the area into possession. The SED is also conducting an investigation of the Bobcat Fire. SCE has accrued a charge for potential losses relating to the Bobcat Fire. The accrued charge corresponds to the lower end of the reasonably estimated range of expected losses that may be incurred in connection with the Bobcat Fire and is subject to change as additional information becomes available. 2017/2018 Wildfire/Mudslide Events Wildfires in SCE's territory in December 2017 and November 2018 caused loss of life, substantial damage to both residential and business properties, and service outages for SCE customers. The investigating government agencies, the Ventura County Fire Department ("VCFD") and California Department of Forestry and Fire Protection ("CAL FIRE"), have determined that the largest of the 2017 fires in SCE's territory originated on December 4, 2017, in the Anlauf Canyon area of Ventura County (the investigating agencies refer to this fire as the "Thomas Fire"), followed shortly thereafter by a second fire that originated near Koenigstein Road in the City of Santa Paula (the "Koenigstein Fire"). The December 4, 2017 fires eventually burned substantial acreage in both Ventura and Santa Barbara Counties. According to CAL FIRE, the Thomas and Koenigstein Fires, collectively, burned over 280,000 acres, destroyed or damaged an estimated 1,343 structures and resulted in two confirmed fatalities. The largest of the November 2018 fires in SCE's territory, known as the "Woolsey Fire," originated in Ventura County and burned acreage in both Ventura and Los Angeles Counties. According to CAL FIRE, the Woolsey Fire burned almost 100,000 acres, destroyed an estimated 1,643 structures, damaged an estimated 364 structures and resulted in three confirmed fatalities. Two additional fatalities have been associated with the Woolsey Fire. The Thomas Fire, the Koenigstein Fire, the Montecito Mudslides (defined below) and the Woolsey Fire are each referred to as a "2017/2018 Wildfire/Mudslide Event," and, collectively, referred to as the "2017/2018 Wildfire/Mudslide Events." As described below, multiple lawsuits related to the Thomas and Koenigstein Fires and the Woolsey Fire have been initiated against SCE and Edison International. Some of the Thomas and Koenigstein Fires lawsuits claim that SCE and Edison International have responsibility for the damages caused by debris flows and flooding in Montecito and surrounding areas in January 2018 (the "Montecito Mudslides") based on a theory alleging that SCE has responsibility for the Thomas and/or Koenigstein Fires and further alleging that the Thomas and/or Koenigstein Fires proximately caused the Montecito Mudslides. According to Santa Barbara County initial reports, the Montecito Mudslides destroyed an estimated 135 structures, damaged an estimated 324 structures, and resulted in 21 confirmed fatalities, with two additional fatalities presumed. Based on information available to SCE and consideration of the risks associated with litigation, Edison International and SCE expect to incur a material loss in connection with the remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events. The 2017/2018 Wildfire/Mudslide Events are discussed further below. As of December 31, 2020, Edison International and SCE had paid $1.8 billion in settlements and had estimated losses of $4.4 billion reflected on their consolidated balance sheets related to the 2017/2018 Wildfire/Mudslide Events, consisting of $2.2 billion subject to settlements executed after December 31, 2020 and $2.2 billion for remaining alleged and potential claims. As of the same date, Edison International and SCE also had assets for remaining expected recoveries from insurance of $708 million, reflected as a short-term asset, and through FERC electric rates of $89 million on their consolidated balance sheets related to the 2017/2018 Wildfire/Mudslide Events. The estimated losses for the 2017/2018 Wildfire/Mudslide Events do not include an estimate of any potential fines or penalties that could be levied against SCE in connection with the 2017/2018 Wildfire/Mudslide Events. Edison International and SCE are currently unable to reasonably estimate the magnitude of any such fines or penalties, or the associated timing if they were to be imposed. Estimated losses for the 2017/2018 Wildfire/Mudslide Events litigation are based on a number of assumptions and are subject to change as additional information becomes available. Actual losses incurred may be higher or lower than estimated based on several factors, including: the uncertainty as to the legal and factual determinations to be made during litigation, including uncertainty as to the contributing causes of the 2017/2018 Wildfire/Mudslide Events, the complexities associated with fires that merge, whether inverse condemnation will be held applicable to SCE with respect to damages caused by the Montecito Mudslides, the preliminary nature of the litigation processes, the uncertainty in estimating damages that may be alleged, and the uncertainty as to how these factors impact future settlements. The CPUC and FERC may not allow SCE to recover uninsured losses through electric rates if it is determined that such losses were not reasonably or prudently incurred. See "Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates" below for additional information. External Investigations and Internal Review The VCFD and CAL FIRE have jointly issued reports concerning their findings regarding the causes of the Thomas Fire and the Koenigstein Fire. The reports did not address the causes of the Montecito Mudslides. SCE has also received a non-final redacted draft of a report from the VCFD regarding Woolsey Fire (the "Redacted Woolsey Report"). SCE anticipates that the VCFD will release its final report regarding the Woolsey Fire in 2021. The VCFD and CAL FIRE findings do not determine legal causation of or assign legal liability for the Thomas, Koenigstein or Woolsey Fires; final determinations of legal causation and liability would only be made during lengthy and complex litigation. The CPUC's Safety and Enforcement Division ("SED") is also conducting investigations to assess SCE's compliance with applicable rules and regulations in areas impacted by the Thomas, Koenigstein and Woolsey Fires and the CPUC may initiate proceedings to investigate these matters after the SED's investigations are completed. Edison International and SCE understand that the California Attorney General's Office has completed its investigation of the Thomas Fire without pursuing criminal charges. Edison International and SCE are aware of an ongoing investigation by the California Attorney General's Office of the Woolsey Fire for the purpose of determining whether any criminal violations have occurred. SCE could be subject to material fines, penalties, or restitution if it is determined that it failed to comply with applicable laws and regulations. SCE is not aware of any basis for felony liability with regards to the Thomas Fire, the Koenigstein Fire or the Woolsey Fire. SCE's internal review into the facts and circumstances of each of the 2017/2018 Wildfire/Mudslide Events is complex and time consuming. SCE expects to obtain and review additional information and materials in the possession of third parties during the course of its internal reviews and the litigation processes. Thomas Fire On March 13, 2019, the VCFD and CAL FIRE jointly issued a report concluding, after ruling out other possible causes, that the Thomas Fire was started by SCE power lines coming into contact during high winds, resulting in molten metal falling to the ground. However, the report does not state that their investigation found molten metal on the ground. At this time, based on available information, SCE has not determined whether its equipment caused the Thomas Fire. Based on publicly available radar data showing a smoke plume in the Anlauf Canyon area emerging in advance of the report's indicated start time, SCE believes that the Thomas Fire started at least 12 minutes prior to any issue involving SCE's system and at least 15 minutes prior to the start time indicated in the report. SCE is continuing to assess the extent of damages that may be attributable to the Thomas Fire. Koenigstein Fire On March 20, 2019, the VCFD and CAL FIRE jointly issued a report finding that the Koenigstein Fire was caused when an energized SCE electrical wire separated and fell to the ground along with molten metal particles and ignited the dry vegetation below. As previously disclosed, SCE believes that its equipment was associated with the ignition of the Koenigstein Fire. SCE is continuing to assess the extent of damages that may be attributable to the Koenigstein Fire. Montecito Mudslides SCE's internal review includes inquiry into whether the Thomas and/or Koenigstein Fires proximately caused or contributed to the Montecito Mudslides, whether, and to what extent, the Thomas and/or Koenigstein Fires were responsible for the damages in the Montecito area and other factors that potentially contributed to the losses that resulted from the Montecito Mudslides. Many other factors, including, but not limited to, weather conditions and insufficiently or improperly designed and maintained debris basins, roads, bridges and other channel crossings, could have proximately caused, contributed to or exacerbated the losses that resulted from the Montecito Mudslides. At this time, based on available information, SCE has not been able to determine whether the Thomas Fire or the Koenigstein Fire, or both, were responsible for the damages in the Montecito area. In the event that SCE is determined to have caused the fire that spread to the Montecito area, SCE cannot predict whether, if fully litigated, the courts would conclude that the Montecito Mudslides were caused or contributed to by the Thomas and/or Koenigstein Fires or that SCE would be liable for some or all of the damages caused by the Montecito Mudslides. Woolsey Fire SCE's internal review into the facts and circumstances of the Woolsey Fire is ongoing. SCE has reported to the CPUC that there was an outage on SCE's electric system in the vicinity of where the Woolsey Fire reportedly began on November 8, 2018. SCE is aware of witnesses who saw fire in the vicinity of SCE's equipment at the time the fire was first reported. While SCE did not find evidence of downed electrical wires on the ground in the suspected area of origin, it observed a pole support wire in proximity to an electrical wire that was energized prior to the outage. The Redacted Woolsey Report states that the VCFD investigation team determined that electrical equipment owned and operated by SCE was the cause of the Woolsey Fire. Absent additional evidence, SCE believes that it is likely that its equipment was associated with the ignition of the Woolsey Fire. SCE expects to obtain and review additional information and materials in the possession of CAL FIRE and others during the course of its internal review and the Woolsey Fire litigation process, including SCE equipment that has been retained by CAL FIRE. Litigation Multiple lawsuits related to the 2017/2018 Wildfire/Mudslide Events naming SCE as a defendant have been filed by three categories of plaintiffs: individual plaintiffs, subrogation plaintiffs and public entity plaintiffs. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. Because potential plaintiffs can still timely file claims related to the 2017/2018 Wildfire/Mudslide Events, SCE expects to be the subject of additional lawsuits related to the events. The litigation could take a number of years to be resolved because of the complexity of the matters and number of plaintiffs. As of February 18, 2021, SCE was aware of at least 295 lawsuits, representing approximately 4,000 plaintiffs, related to the Thomas and Koenigstein Fires naming SCE as a defendant. One hundred fifty of the 295 lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. At least four of the lawsuits were filed as purported class actions. The lawsuits, which have been filed in the superior courts of Ventura, Santa Barbara and Los Angeles Counties allege, among other things, negligence, inverse condemnation, trespass, private nuisance, and violations of the public utilities and health and safety codes. An initial trial for a limited number of plaintiffs, sometimes referred to as a bellwether trial, on certain fire only matters is currently scheduled for July 19, 2021. The bellwether trial date may be further delayed to provide SCE and certain of the individual plaintiffs in the Thomas and Koenigstein Fire litigation the opportunity to pursue settlements of claims under a program adopted to promote an efficient and orderly settlement process. Seventy-two of the 295 lawsuits mentioned in the paragraph above allege that SCE has responsibility for the Thomas and/or Koenigstein Fires and that the Thomas and/or Koenigstein Fires proximately caused the Montecito Mudslides, resulting in the plaintiffs' claimed damages. Forty of the 72 Montecito Mudslides lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. In addition to other causes of action, some of the Montecito Mudslides lawsuits also allege personal injury and wrongful death. A bellwether jury trial previously scheduled for October 12, 2020 was vacated due to the wide-spread disruption being caused by the COVID-19 pandemic. As of February 18, 2021, SCE was aware of at least 301 lawsuits, representing approximately 6,000 plaintiffs, related to the Woolsey Fire naming SCE as a defendant. Two hundred forty-three of the 301 lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. At least two of the lawsuits were filed as purported class actions. The lawsuits, which have been filed in the superior courts of Ventura and Los Angeles Counties allege, among other things, negligence, inverse condemnation, personal injury, wrongful death, trespass, private nuisance, and violations of the public utilities and health and safety codes. A bellwether jury trial is currently scheduled for June 1, 2021. The Thomas and Koenigstein Fires and Montecito Mudslides lawsuits are being coordinated in the Los Angeles Superior Court. The Woolsey Fire lawsuits have also been coordinated in the Los Angeles Superior Court. On October 4, 2018, the Superior Court denied Edison International's and SCE's challenge to the application of inverse condemnation to SCE with respect to the Thomas and Koenigstein Fires and, on February 26, 2019, the California Supreme Court denied SCE's petition to review the Superior Court's decision. In January 2019, SCE filed a cross-complaint against certain local public entities alleging that failures by these entities, such as failure to adequately plan for flood hazards and build and maintain adequate debris basins, roads, bridges and other channel crossings, among other things, caused, contributed to or exacerbated the losses that resulted from the Montecito Mudslides. These cross-claims in the Montecito Mudslides litigation were not released as part of the Local Public Entity Settlements (as defined below). Additionally, in September 2018, a derivative lawsuit for breach of fiduciary duties and unjust enrichment was filed in the Los Angeles Superior Court against certain current and former members of the Boards of Directors of Edison International and SCE. Edison International and SCE are identified as nominal defendants in the action. The derivative lawsuit generally alleges that the individual defendants violated their fiduciary duties by causing or allowing SCE to operate in an unsafe manner in violation of relevant regulations, resulting in substantial liability and damage from the Thomas and Koenigstein Fires and the Montecito Mudslides. The lawsuit is currently stayed. In November 2018, a purported class action lawsuit alleging securities fraud and related claims was filed in federal court against Edison International, SCE and certain current and former officers of Edison International and SCE. The plaintiff alleges that Edison International and SCE made false and/or misleading statements in filings with the Securities and Exchange Commission by failing to disclose that SCE had allegedly failed to maintain its electric transmission and distribution networks in compliance with safety regulations, and that those alleged safety violations led to fires that occurred in 2017 and 2018, including the Thomas Fire and the Woolsey Fire. In January 2019, two separate derivative lawsuits alleging breach of fiduciary duties, securities fraud, misleading proxy statements, unjust enrichment, and related claims were filed in federal court against certain current and former members of the Boards of Directors and certain current and former officers of Edison International and SCE. Edison International and SCE are named as nominal defendants in those actions. The derivative lawsuits generally allege that the individual defendants breached their fiduciary duties and made misleading statements or allowed misleading statements to be made (i) between March 21, 2014 and August 10, 2015, with respect to certain ex parte communications between SCE and CPUC decision-makers concerning the settlement of the San Onofre Order Instituting Investigation proceeding (the "San Onofre OII") and (ii) from February 23, 2016 to the present, concerning compliance with applicable laws and regulations concerning electric system maintenance and operations related to wildfire risks. The lawsuits generally allege that these breaches of duty and misstatements led to substantial liability and damage resulting from the disclosure of SCE's ex parte communications in connection with the San Onofre OII settlement, and from the 2017/2018 Wildfire/Mudslide Events. The lawsuits are currently stayed. Settlements In the fourth quarter of 2019, SCE paid $360 million to a number of local public entities to resolve those parties' collective claims arising from the 2017/2018 Wildfire/Mudslide Events (the "Local Public Entity Settlements"). In the third quarter of 2020, Edison International and SCE entered into an agreement (the "TKM Subrogation Settlement") under which all of the insurance subrogation plaintiffs' in the Thomas Fire, Koenigstein Fire and Montecito Mudslides litigation (the "TKM Subrogation Plaintiffs") collective claims arising from the Thomas Fire, Koenigstein Fire or Montecito Mudslides have been resolved. Under the TKM Subrogation Settlement, SCE paid the TKM Subrogation Plaintiffs an aggregate of $1.2 billion in October 2020 and also agreed to pay $0.555 for each dollar in claims to be paid by the TKM Subrogation Plaintiffs to their policy holders on or before July 15, 2023, up to an agreed upon cap. In January 2021, Edison International and SCE entered into an agreement (the "Woolsey Subrogation Settlement") under which all of the insurance subrogation plaintiffs' in the Woolsey Fire litigation (the "Woolsey Subrogation Plaintiffs") collective claims arising from the Woolsey Fire have been resolved. Under the Woolsey Subrogation Settlement, SCE agreed to pay the Woolsey Subrogation Plaintiffs an aggregate of $2.2 billion by April 22, 2021. SCE has also agreed to pay $0.67 for each dollar in claims to be paid by the Woolsey Subrogation Plaintiffs to their policy holders on or before July 15, 2023, up to an agreed upon cap. SCE has |

Leases [Abstract] | |
Leases | Leases Leases as Lessee SCE enters into various agreements to purchase power, electric capacity and other energy products that may be accounted for as leases when SCE has dispatch rights that determine when and how a plant runs. SCE also leases property and equipment primarily related to vehicles, office space and other equipment. The terms of the contracts included in the table below are primarily 3 to 20 years for PPA leases, 5 to 72 years for office leases, and 5 to 13 years for the remaining other operating leases. The following table summarizes SCE's lease payments for operating and finance leases as of December 31, 2020: (in millions) PPA Operating Leases 1 Other Operating Leases 2 PPA Finance Leases 1 2021 $ 204 $ 39 $ 1 2022 208 32 1 2023 159 26 1 2024 47 21 — 2025 47 18 — Thereafter 443 104 5 Total lease payments 1,108 240 8 Amount representing interest 3 203 60 4 Lease liabilities $ 905 $ 180 $ 4 1 Excludes expected purchases from most renewable energy contracts, which do not meet the definition of a lease payment since renewable power generation is contingent on external factors. 2 Excludes escalation clauses based on consumer price or other indices and residual value guarantees that are not considered probable at the commencement date of the lease. 3 Lease payments are discounted to their present value using SCE's incremental borrowing rates.

Related Party Transactions [Abstract] | |
Related-Party Transactions | Related-Party Transactions Edison International and SCE provide and receive various services to and from its subsidiaries and affiliates. Services provided to Edison International by SCE are priced at fully loaded cost (i.e., direct cost of good or service and allocation of overhead cost). Specified administrative services performed by Edison International or SCE employees, such as payroll and employee benefit programs, are shared among all affiliates of Edison International. Costs are allocated based on one of the following formulas: percentage of time worked, equity in investment and advances, number of employees, or multi-factor (operating revenue, operating expenses, total assets and number of employees). Edison International allocates various corporate administrative and general costs to SCE and other subsidiaries using established allocation factors. For the years ended December 31, 2020, 2019 and 2018, SCE purchased wildfire liability insurance for premiums of $176 million, $260 million and $22 million respectively, from Edison Insurance Services, Inc. ("EIS"), a wholly-owned subsidiary of Edison International. EIS fully reinsured the exposure for these policies through the commercial reinsurance market, with reinsurance limits and premiums equal to those of the insurance purchased by SCE. The related-party transactions included in SCE's consolidated balance sheets for wildfire-related insurance purchased from EIS and related expected insurance recoveries were as follows: December 31, (in millions) 2020 2019 Current insurance receivable due from affiliate $ 268 $ — Long-term insurance receivables due from affiliate — 803 Prepaid insurance 1 56 10 1 Reflected in "Prepaid expenses" on SCE's consolidated balance sheets. |

Basis of Presentation The accompanying condensed financial statements of Edison International Parent should be read in conjunction with the consolidated financial statements and notes thereto of Edison International and subsidiaries ("Registrant") included in this Form 10-K. Edison International Parent's significant accounting policies are consistent with those of the Registrant, SCE and other wholly owned and controlled subsidiaries. Dividends Received Edison International Parent received cash dividends from SCE of $1.3 billion, $400 million and $788 million in 2020, 2019 and 2018, respectively. Dividend Restrictions CPUC holding company rules require that SCE's dividend policy be established by SCE's Board of Directors on the same basis as if SCE were a stand-alone utility company, and that the capital requirements of SCE, as deemed to be necessary to meet SCE's electricity service obligations, shall receive first priority from the Boards of Directors of both Edison International and SCE. In addition, the CPUC regulates SCE's capital structure which limits the dividends it may pay to its shareholders. Effective January 1, 2020, the common equity component of SCE's CPUC authorized capital structure was increased from 48% to 52% on a weighted average basis over the January 1, 2020 to December 31, 2022 compliance period. Under AB 1054, the impact of SCE's contributions to the Wildfire Insurance Fund are excluded from the measurement of SCE's CPUC-jurisdictional authorized capital structure. For further information, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies." In May 2020, the CPUC issued a decision on SCE's application to the CPUC for waiver of compliance with its equity ratio requirement, that allows SCE to exclude from its equity ratio calculations (i) net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events and (ii) debt issued for the purpose of paying claims related to the 2017/2018 Wildfire/Mudslide Events up to an amount equal to the net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events. The temporary exclusion will lapse on May 7, 2022 or when a determination regarding cost recovery for the 2017/2018 Wildfire/Mudslide Events is made, whichever comes earlier. If the CPUC has not made a determination regarding cost recovery by May 7, 2022, SCE is permitted to file another application for a waiver of compliance with its equity ratio requirement. In the interim, SCE is required to notify the CPUC if an adverse financial event reduces SCE's spot equity ratio by more than one percent from the level most recently filed with the CPUC in the proceeding. The last spot equity ratio SCE filed with the CPUC in the proceeding did not exclude the then $1.8 billion net charge and was 45.2% as of December 31, 2018 (at the time the common equity component of SCE's CPUC authorized capital structure was required to remain at or above 48% on a weighted average basis over the applicable 37-month period). SCE's spot equity ratio on December 31, 2018 would have been 48.7% had the $1.8 billion net charge at December 31, 2018 been excluded, therefore SCE will notify the CPUC if its spot ratio drops below 47.7% in any quarter. See "Notes to Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies—SCE Dividends." Note 2. Debt and Equity Financing Long-Term Debt In April 2020, Edison International Parent issued $400 million of 4.95% senior notes due 2025. The proceeds were used to repay all $400 million of Edison International Parent's outstanding 2.125% Senior Notes due in 2020. In addition, at December 31, 2020, Edison International Parent had $400 million of 2.40% senior notes due in 2022, $300 million of 3.125% senior notes due 2022, $400 million of 2.95% senior notes due in 2023, $500 million of 3.55% senior notes due 2024, $600 million of 5.75% senior notes due in 2027 and $550 million of 4.125% senior notes due in 2028. At December 31, 2019, Edison International Parent had $400 million of 2.125% senior notes due in 2020, $400 million of 2.40% senior notes due in 2022, $400 million of 2.95% senior notes due in 2023 and $550 million of 4.125% senior notes due in 2028. Credit Agreements and Short-Term Debt The following table summarizes the status of the credit facility at December 31, 2020: (in millions) Commitment $ 1,500 Outstanding borrowings 1 130 Amount available $ 1,370 1 At December 31, 2020 Edison International Parent had $130 million outstanding commercial paper, net of discount, at a weighted-average interest rate of 0.42%. At December 31, 2019 Edison International Parent did not have any outstanding commercial paper. In March 2020, Edison International Parent borrowed $800 million under a term loan agreement due in March 2021 with a variable interest rate based on LIBOR plus 1.125%. The proceeds were used for general corporate purposes. In May 2020, Edison International repaid the outstanding balance of the term loan using the proceeds from issuance of common stock in a registered direct offering. The debt covenant in Edison International Parent's credit facility requires a consolidated debt to total capitalization ratio of less than or equal to 0.70 to 1. At December 31, 2020, Edison International's consolidated debt to total capitalization ratio was 0.59 to 1. Equity In May 2020, Edison International issued 14,181,882 shares of common stock in a registered direct offering and received approximately $800 million in proceeds, before deducting fees and offering expenses of $14 million. The proceeds were used to pay off debt outstanding under a term loan agreement and for general corporate purposes. Refer to Note 2 for details of the term loan. In May 2019, Edison International filed a prospectus supplement and executed several distribution agreements with certain sales agents to establish an "at-the-market" ("ATM") program under which it may sell shares of its common stock having an aggregate sales price of up to $1.5 billion. During the three months ended December 31, 2020, Edison International did not issue any shares through the ATM program. During the twelve months ended December 31, 2020, Edison International issued 391,501 shares through the ATM program and received proceeds of $27 million, net of fees and offering expenses of $0.3 million. During the three and twelve months ended December 31, 2019, Edison International issued 2,824,261 shares through the ATM program and received proceeds of $198 million, net of fees and offering expenses of $2 million. The proceeds from the sales were used for equity contributions to SCE and for general corporate and working capital purposes. As of December 31, 2020, shares of common stock having an aggregate offering price of $1.3 billion remained available to be sold under the ATM program. Edison International has no obligation to sell the remaining available shares. Edison International continued to settle its ongoing common stock requirements of various internal programs through issuance of new common stock. During the twelve months ended December 31, 2020, 1,644,500 shares of common stock were purchased by employees through the 401(k) defined contribution savings plan for net cash receipts of $99 million, 387,425 shares of common stock were issued as stock compensation awards for net cash receipts of $16 million, 280,707 shares of new common stock were issued in lieu of distributing $17 million to shareholders opting to receive dividend payments in the form of additional common stock and 35,999 shares of common stock related to optional cash investments of $2 million. During the twelve months ended December 31, 2019, 595,200 shares of common stock were purchased by employees through the 401(k) defined contribution savings plan for net cash receipts of $41 million, 423,569 shares of common stock were issued as stock compensation awards for net cash receipts of $22 million and 125,481 shares of new common stock were issued in lieu of distributing $8 million to shareholders opting to receive dividend payments in the form of additional common stock. Edison International did not have optional cash investment issuances in December 31, 2019. Note 3. Related-Party Transactions Edison International's Parent expense from services provided by SCE was $2 million in 2020, $2 million in 2019 and $2 million in 2018. Edison International's Parent interest expense from loans due to affiliates was $4 million in 2020 and $5 million in 2019 and 2018. Edison International Parent had current related-party receivables of $43 million and $272 million and current related-party payables of $323 million and $198 million at December 31, 2020 and 2019, respectively. Edison International Parent had long-term related-party receivables of $68 million and $73 million at December 31, 2020 and 2019, respectively, and long-term related-party payables of $219 million and $213 million at December 31, 2020 and 2019, respectively. Edison Mission Energy ("EME"), a wholly-owned subsidiary of Edison International, emerged from bankruptcy in 2014 and retained a lease investment in a hydroelectric power plant in Vidalia, Louisiana. In November 2020, the lessee exercised an option in the lease agreement and purchased the asset upon expiration of the lease term. EME received net proceeds of $132 million from sale, which was transferred to Edison International Parent as a related-party note and included in current related-party payables. Note 4.

Summary of Significant Accoun_2
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
Dec. 31, 2020 | |
Accounting Policies [Abstract] | |
Organization and Basis of Presentation | Organization and Basis of Presentation Edison International is the parent holding company of Southern California Edison Company ("SCE") and Edison Energy Group, Inc. ("Edison Energy Group"). SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity to an approximately 50,000 square mile area of southern California. Edison Energy Group is a holding company for Edison Energy, LLC ("Edison Energy") which is engaged in the competitive business of providing data-driven energy solutions to commercial, institutional and industrial customers. Edison Energy's business activities are currently not material to report as a separate business segment. These combined notes to the consolidated financial statements apply to both Edison International and SCE unless otherwise described. Edison International's consolidated financial statements include the accounts of Edison International, SCE and other wholly owned and controlled subsidiaries. References to Edison International refer to the consolidated group of Edison International and its subsidiaries. References to "Edison International Parent and Other" refer to Edison International Parent and its competitive subsidiaries and "Edison International Parent" refer to Edison International on a stand-alone basis, not consolidated with its subsidiaries. SCE's consolidated financial statements include the accounts of SCE and its wholly owned and controlled subsidiaries. All intercompany transactions have been eliminated from the consolidated financial statements. Edison International's and SCE's accounting policies conform to accounting principles generally accepted in the United States of America, including the accounting principles for rate-regulated enterprises, which reflect the ratemaking policies of the California Public Utility Commission ("CPUC") and the Federal Energy Regulatory Commission ("FERC"). SCE applies authoritative guidance for rate-regulated enterprises to the portion of its operations in which regulators set rates at levels intended to recover the estimated costs of providing service, plus a return on net investments in assets, or rate base. Regulators may also impose certain penalties or grant certain incentives. Due to timing and other differences in the collection of electric utility revenue, these principles require an incurred cost that would otherwise be charged to expense by a non-regulated entity to be capitalized as a regulatory asset if it is probable that the cost is recoverable through future rates; and conversely the principles require recording of a regulatory liability for amounts collected in rates to recover costs expected to be incurred in the future or amounts collected in excess of costs incurred and refundable to customers. In addition, SCE recognizes revenue and regulatory assets from alternative revenue programs, which enables the utility to adjust future rates in response to past activities or completed events, if certain criteria are met, even for programs that do not qualify for recognition of "traditional" regulatory assets and liabilities. SCE assesses, at the end of each reporting period, whether regulatory assets are probable of future recovery. See Note 11 for composition of regulatory assets and liabilities. |
Use of Estimates | The preparation of financial statements in conformity with United States generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reported period. Actual results could differ from those estimates. Certain prior year amounts have been conformed to the current year's presentation, including the presentation of long-term insurance receivables on the consolidated balance sheets of Edison International and Southern California Edison, previously presented as other long-term assets. |
Cash and Cash Equivalents | Cash equivalents include investments in money market funds. Generally, the carrying value of cash equivalents equals the fair value, as these investments have original maturities of three months or less. |
Allowance for Uncollectible Accounts | Allowance for Uncollectible Accounts The allowance for uncollectible accounts is recorded based on SCE's estimate of expected credit losses and adjusted over the life of the receivables as needed. Since the customer base of SCE is concentrated in Southern California and exposes SCE to a homogeneous set of economic conditions, the allowance is measured on a collective basis on the historical amounts written-off, assessment of customer collectibility and current economic trends, including unemployment rates and any likelihood of recession for the region. At December 31, 2020, this included the estimated impacts of the COVID-19 pandemic. |
Inventory | InventorySCE's inventory is primarily composed of materials, supplies and spare parts, and generally stated at weighted average cost. |
Emission Allowances and Energy Credits | Emission Allowances and Energy CreditsSCE is allocated greenhouse gas ("GHG") allowances annually which it is then required to sell into quarterly auctions. GHG proceeds from the auctions are recorded as a regulatory liability to be refunded to customers. SCE purchases GHG allowances in quarterly auctions or from counterparties to satisfy its GHG emission compliance obligations and recovers such costs of GHG allowances from customers. GHG allowances held for use are classified as "Other current assets" on the consolidated balance sheets and are stated, similar to an inventory method, at the lower of weighted average cost or market. |
Property, Plant and Equipment | Property, Plant and Equipment SCE plant additions, including eligible replacements and betterments, are capitalized. Direct material and labor and indirect costs such as construction overhead, administrative and general costs, pension and benefits, and property taxes are capitalized as part of plant additions. The CPUC authorizes a capitalization rate for each of the indirect costs which are allocated to each project based on either labor or total costs. Estimated useful lives authorized by the CPUC in the 2018 General Rate Case ("GRC") and weighted average useful lives of SCE's property, plant and equipment, are as follows: Estimated Useful Lives Weighted Average Useful Lives Generation plant 10 years to 55 years 36 years Distribution plant 20 years to 65 years 48 years Transmission plant 45 years to 65 years 54 years General plant and other 5 years to 60 years 25 years Depreciation of utility property, plant and equipment is computed on a straight-line, remaining-life basis. SCE's depreciation expense was $1.8 billion, $1.7 billion and $1.7 billion for 2020, 2019 and 2018, respectively. Depreciation expense stated as a percent of average original cost of depreciable utility plant was, on a composite basis, 3.6%, 3.6% and 3.7% for 2020, 2019 and 2018, respectively. The original costs of retired property are charged to accumulated depreciation. See Note 2 for further information. Nuclear fuel for the Palo Verde Nuclear Generating Station ("Palo Verde") is recorded as utility plant (nuclear fuel in the fabrication and installation phase is recorded as construction in progress) in accordance with CPUC ratemaking procedures. Palo Verde nuclear fuel is amortized using the units of production method. Allowance for funds used during construction ("AFUDC") represents the estimated cost of debt and equity funds that finance utility-plant construction and is capitalized during certain plant construction. AFUDC is recovered in rates through depreciation expense over the useful life of the related asset. AFUDC equity represents a method to compensate SCE for the estimated cost of equity used to finance utility plant additions and is recorded as part of construction in progress. AFUDC equity was $121 million, $101 million and $104 million in 2020, 2019 and 2018, respectively, and is reflected in "Other income." AFUDC debt was $53 million, $63 million and $44 million in 2020, 2019 and 2018, respectively and is reflected as a reduction of "Interest expense." Major Maintenance Major maintenance costs for SCE's power plant facilities and equipment are expensed as incurred. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets Impairments of long-lived assets are evaluated based on a review of estimated future cash flows expected to be generated whenever events or changes in circumstances indicate that the carrying amount of such investments or assets may not be recoverable. If the carrying amount of a long-lived asset exceeds expected future cash flows, undiscounted and without interest charges, an impairment loss is recognized in the amount of the excess of fair value over the carrying amount. Fair value is determined via market, cost and income-based valuation techniques, as appropriate. |
Prepaid Insurance | Initial and annual contributions to the wildfire insurance fund established pursuant to California Assembly Bill 1054 (the "Wildfire Insurance Fund" and "AB 1054") Edison International and SCE accounted for the contributions to the Wildfire Insurance Fund similarly to prepaid insurance. No period of coverage was provided in AB 1054, therefore expense is being allocated to periods ratably based on an estimated period of coverage. Edison International and SCE have a $2.4 billion and $2.8 billion long-term asset at December 31, 2020 and December 31, 2019, respectively, and a $323 million current asset reflected as "Wildfire Insurance Fund contributions" in the consolidated balance sheets for the initial $2.4 billion contribution made during the third quarter of 2019 and the present value of annual contributions SCE committed to make to the Wildfire Insurance Fund, reduced by amortization at both December 31, 2020 and December 31, 2019. A long-term liability of $703 million and $785 million have been reflected in "Other deferred credits and other long-term liabilities" for the present value of unpaid contribution amounts, at December 31, 2020 and December 31, 2019, respectively. Contributions were discounted to the present value at the date SCE committed to participate in the Wildfire Insurance Fund using US treasury interest rates. During 2020 a period of 10 years was used to amortize the asset. All expenses related to the contributions are being reflected in "Operation and maintenance" in the consolidated statements of income. Changes in the estimated period of coverage provided by the Wildfire Insurance Fund could lead to material changes in future expense recognition. In estimating the period of coverage Edison International and SCE used Monte Carlo simulations based on five years (2014 – 2018) of historical data from wildfires caused by electrical utility equipment to estimate expected losses. The details of the operation of the Wildfire Insurance Fund and estimates related to claims by SCE, Pacific Gas & Electric Company ("PG&E") and San Diego Gas & Electric ("SDG&E") against the fund have been applied to the expected loss simulations to estimate the period of coverage of the fund. The most sensitive inputs to the estimated period of coverage are the expected frequency of wildfire events caused by investor-owned utility electrical equipment and the estimated costs associated with those forecasted events. Edison International and SCE evaluate all inputs annually, or upon claims being made from the fund for catastrophic wildfires, and the expected life of the insurance fund will be adjusted as required. Based on information available in the first quarter of 2021 regarding catastrophic wildfires during 2019 and 2020, SCE reassessed its estimate of the life of the Wildfire Insurance Fund. Using 7 years of historical data (2014 – 2020) of wildfires caused by electrical utility equipment to create Monte Carlo simulations of expected loss, resulted in the expected life of the Wildfire Insurance Fund increasing from 10 years to 15 years from the date SCE committed to participate in the Wildfire Insurance Fund. Edison International and SCE will assess the Wildfire Insurance Fund contribution assets for impairment in the event that a participating utility's electrical equipment is found to be the substantial cause of a catastrophic wildfire, based on the ability of SCE to benefit from the coverage provided by the Wildfire Insurance Fund in an amount equal to the recorded assets. |
Goodwill | Goodwill Edison International assesses goodwill through an annual goodwill impairment test, at the reporting unit level as of October 1 of each year. Edison International updates its goodwill impairment test between annual tests if events occur or circumstances change such that it is more likely than not that the fair value of a reporting unit is below its carrying value. |
Nuclear Decommissioning and Asset Retirement Obligations | Nuclear Decommissioning and Asset Retirement Obligations The fair value of a liability for an asset retirement obligation ("ARO") is recorded in the period in which it is incurred, including a liability for the fair value of a conditional ARO, if the fair value can be reasonably estimated even though uncertainty exists about the timing and/or method of settlement. When an ARO liability is initially recorded, SCE capitalizes the cost by increasing the carrying amount of the related long-lived asset. For each subsequent period, the liability is increased for accretion expense and the capitalized cost is depreciated over the useful life of the related asset. SCE has not recorded an ARO for assets that are expected to operate indefinitely or where SCE cannot estimate a settlement date (or range of potential settlement dates). As such, ARO liabilities are not recorded for certain retirement activities, including certain hydroelectric facilities. The following table summarizes the changes in SCE's ARO liability: December 31, (in millions) 2020 2019 Beginning balance $ 3,029 $ 3,031 Accretion 1 160 166 Revisions (36) 4 Liabilities settled (223) (172) Ending balance $ 2,930 $ 3,029 1 An ARO represents the present value of a future obligation. Accretion is an increase in the liability to account for the time value of money resulting from discounting. AROs related to decommissioning of SCE's nuclear power facilities are based on site-specific studies conducted as part of each Nuclear Decommissioning Cost Triennial Proceeding ("NDCTP") conducted before the CPUC. Revisions of an ARO are established for updated site-specific decommissioning cost estimates. The ARO for decommissioning SCE's San Onofre Nuclear Generating Station ("San Onofre") and Palo Verde nuclear power facilities is $2.6 billion as of December 31, 2020. The liability to decommission SCE's nuclear power facilities is based on a 2017 decommissioning study that was filed as part of the 2018 NDCTP for San Onofre Units 1, 2 and 3, and a 2019 decommissioning study for Palo Verde. SCE revised the ARO for Palo Verde in 2020 and for San Onofre Units 1, 2 and 3 in 2018 to reflect updated decommissioning cost estimates. SCE records an ARO regulatory liability as a result of timing differences between the recognition of costs and the recovery of costs through the ratemaking process. For further information, see Note 11. Decommissioning of San Onofre Unit 1 began in 1999 and the transfer of spent nuclear fuel from Unit 1 to dry cask storage in the Independent Spent Fuel Storage Installation ("ISFSI") was completed in 2005. Major decommissioning work for Unit 1 has been completed except for certain underground work. Decommissioning of San Onofre Units 2 and 3 began in June 2013 and the spent nuclear fuel transfer from San Onofre Units 2 and 3 to dry cask storage in the ISFSI was completed in August 2020. In October 2019, the California Coastal Commission approved SCE's application for the Coastal Development Permit, the principal discretionary permit required to start major decommissioning activities at San Onofre. In August 2020, SCE commenced major decommissioning activities at San Onofre in accordance with the terms of the permit. Decommissioning costs, which are recovered through customer rates over the term of each nuclear facility's operating license, are recorded as a component of depreciation expense, with a corresponding credit to the ARO regulatory liability. Due to regulatory recovery of SCE's nuclear decommissioning expense, prudently incurred costs for nuclear decommissioning activities do not affect SCE's earnings. Amortization of the ARO asset (included within the unamortized nuclear investment) and accretion of the ARO liability are deferred as decreases to the ARO regulatory liability account, resulting in no impact on earnings. SCE has collected in rates amounts for the future decommissioning of its nuclear assets and has placed those amounts in independent trusts. Amounts collected in rates in excess of the ARO liability are classified as regulatory liabilities. Changes in the estimated costs, timing of decommissioning or the assumptions underlying these estimates could cause material revisions to the estimated total cost to decommission. SCE currently estimates that it will spend approximately $6.6 billion through 2079 to decommission its nuclear facilities. This estimate is based on SCE's decommissioning cost methodology used for ratemaking purposes, escalated at rates ranging from 0.6% to 7.5% (depending on the cost element) annually. These costs are expected to be funded from independent decommissioning trusts. SCE estimates annual after-tax earnings on the decommissioning funds of 1.3% to 4.1% dependent on asset class. If the assumed return on trust assets is not earned or costs escalate at higher rates, SCE expects that additional funds needed for decommissioning will be recoverable through future rates, subject to a reasonableness review. See Note 10 for further information. Due to regulatory recovery of SCE's nuclear decommissioning expense, prudently incurred costs for nuclear decommissioning activities do not affect SCE's earnings. SCE's nuclear decommissioning costs are subject to CPUC review through the triennial regulatory proceeding. SCE's nuclear decommissioning trust investments primarily consist of fixed income investments that are classified as available-for-sale and equity investments. Due to regulatory mechanisms, investment earnings and realized gains and losses have no impact on earnings. Unrealized gains and losses on decommissioning trust funds, including impairment, increase or decrease the trust assets and the related regulatory asset or liability and have no impact on electric utility revenue or decommissioning expense. SCE reviews each fixed income security for impairment on the last day of each month. If the fair value on the last day of the month is less than the amortized cost for that security, SCE impairs the disclosed amortized cost. If the fair value is greater or less than the carrying value for that security at the time of sale, SCE recognizes a related realized gain or loss, respectively. |
Deferred Financing Costs | Deferred Financing CostsDebt premium, discount and issuance expenses incurred in connection with obtaining financing are deferred and amortized on a straight-line basis. Under CPUC ratemaking procedures, SCE's debt reacquisition expenses are amortized over the remaining life of the reacquired debt or, if refinanced, the life of the new debt. |
Revenue Recognition | Revenue Recognition Revenue is recognized by Edison International and SCE when a performance obligation to transfer control of the promised goods is satisfied or when services are rendered to customers. This typically occurs when electricity is delivered to customers, which includes amounts for services rendered but unbilled at the end of a reporting period. SCE's Revenue from Contracts with Customers Provision of Electricity SCE principally generates revenue through supplying and delivering electricity to its customers. Rates charged to customers are based on tariff rates, approved by the CPUC and FERC. Starting with SCE's 2021 GRC, revenue will be authorized through quadrennial GRC proceedings, which are intended to provide SCE a reasonable opportunity to recover its costs and earn a return on its CPUC-jurisdictional rate base. The CPUC sets an annual revenue requirement for the base year and the remaining three years are set by a methodology established in the GRC proceeding. Revenue was previously authorized by the CPUC in triennial GRC proceedings. As described above, SCE also earns revenue, with no return, to recover costs for power procurement and other activities. Revenue is authorized by the FERC through a formula rate which is intended to provide SCE a reasonable opportunity to recover transmission capital and operating costs that are prudently incurred, including a return on its FERC-jurisdictional rate base. Under the operation of the formula rate, transmission revenue is updated to actual cost of service annually. For SCE's electricity sales for both residential and non-residential customers, SCE satisfies the performance obligation of delivering electricity over time as the customers simultaneously receive and consume the delivered electricity. Energy sales are typically on a month-to-month implied contract for transmission, distribution and generation services. Revenue is recognized over time as the energy is supplied and delivered to customers and the respective revenue is billed and paid on a monthly basis. CPUC and FERC rates decouple authorized revenue from the volume of electricity sales and the price of energy procured so that SCE receives revenue equal to amounts authorized by the relevant regulatory agencies. As a result, the volume of electricity sold to customers and specific customer classes does not have a direct impact on SCE's financial results. See Note 7 for further information on SCE's revenue. Sales and Use Taxes SCE bills certain sales and use taxes levied by state or local governments to its customers. Included in these sales and use taxes are franchise fees, which SCE pays to various municipalities (based on contracts with these municipalities) in order to operate within the limits of the municipality. SCE bills these franchise fees to its customers based on a CPUC-authorized rate. These franchise fees, which are required to be paid regardless of SCE's ability to collect from the customer, are accounted for on a gross basis. SCE's franchise fees billed to customers were $131 million, $122 million and $133 million for the years ended December 31, 2020, 2019 and 2018, respectively. When SCE acts as an agent for sales and use tax, the taxes are accounted for on a net basis. Amounts billed to and collected from customers for these taxes are remitted to the taxing authorities and are not recognized as electric utility revenue. SCE's Alternative Revenue Programs |
Power Purchase Agreements | Power Purchase Agreements SCE enters into power purchase agreements ("PPAs") in the normal course of business. A power purchase agreement may be considered a variable interest in a variable interest entity ("VIE"). If SCE is the primary beneficiary in the VIE, SCE should consolidate the VIE. None of SCE's PPAs resulted in consolidation of a VIE at December 31, 2020 and 2019. See Note 3 for further discussion of PPAs that are considered variable interests. A PPA may also contain a lease for accounting purposes. See "Leases" below and Note 12 and Note 13 for further discussion of SCE's PPAs, including agreements that are classified as operating and finance leases for accounting purposes. A PPA that does not contain a lease may be classified as a derivative which is recorded at fair value on the consolidated balance sheets. These PPAs may be eligible for an election to designate as a normal purchase and sale, which is accounted for on an accrual basis as an executory contract. See Note 6 for further information on derivative instruments. PPAs that do not meet the above classifications are accounted for on an accrual basis. |
Derivatives Instruments | Derivative Instruments SCE records derivative instruments on its consolidated balance sheets as either assets or liabilities measured at fair value unless otherwise exempted from derivative treatment as normal purchases or sales. The normal purchases and sales exception requires, among other things, physical delivery in quantities expected to be used or sold over a reasonable period in the normal course of business. Realized gains and losses from SCE's derivative instruments are expected to be recovered from or refunded to customers through regulatory mechanisms and, therefore, SCE's fair value changes have no impact on purchased power expense or earnings. SCE does not use hedge accounting for derivative transactions due to regulatory accounting treatment. Where SCE's derivative instruments are subject to a master netting agreement and certain criteria are met, SCE presents its derivative assets and liabilities on a net basis on its consolidated balance sheets. In addition, derivative positions are offset against margin and cash collateral deposits. The results of derivative activities are recorded as part of cash flows from operating activities on the consolidated statements of cash flows. See Note 6 for further information on derivative instruments. |
Leases | Leases On January 1, 2019, Edison International and SCE adopted accounting standards updates that require lessees to recognize a lease on the balance sheet as a right-of-use ("ROU") asset and related lease liability and classify the lease as either operating or finance. A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified assets for a period of time in exchange for consideration. An entity controls the use when it has a right to obtain substantially all of the benefits from the use of the identified asset and has the right to direct the use of the asset. SCE determines if an arrangement is a lease at contract inception. SCE includes both the lease and non-lease components as a single component and accounts for them as a lease for all classes of underlying assets, except energy storage underlying assets which were first contracted in 2020 and for which each component will be separately accounted for. Lease liabilities are recognized based on the present value of the lease payments over the lease term at the commencement date. SCE calculates and uses the rate implicit in the lease if the information is readily available or if not available, SCE uses its incremental borrowing rate in determining the present value of lease payments. Incremental borrowing rates are comprised of underlying risk-free rates and secured credit spreads relative to first mortgage bonds with like tenors of lease term durations. Lease ROU assets are based on the liability, subject to adjustments, such as lease incentives. The ROU assets also include any lease payments made at or before the commencement date. SCE excludes variable lease payments in measuring lease assets and lease liabilities, other than those that depend on an index or a rate or are in substance fixed payments. SCE's lease terms include options to extend or terminate the lease when it is reasonably certain that such options will be exercised. Operating leases are included in "Operating lease right-of-use assets," "Current portion of operating lease liabilities" and "Operating lease liabilities" on the consolidated balance sheets. Finance leases are included in "Utility property, plant and equipment," "Other current liabilities" and "Other deferred credits and other long-term liabilities" on the consolidated balance sheets. SCE enters into power purchase agreements that may contain leases. This occurs when a power purchase agreement designates a specific power plant, SCE obtains substantially all of the economic benefits from the use of the plant and has the right to direct the use of the plant. SCE also enters into a number of agreements to lease property and equipment in the normal course of business, primarily related to vehicles, office space and other equipment. See Note 13 for further discussion of SCE's contracts that are classified as operating and finance leases. |
Stock-Based Compensation | Stock-Based Compensation Stock options, performance shares, deferred stock units and restricted stock units have been granted under Edison International's long-term incentive compensation programs. For equity awards that are settled in common stock, Edison International either issues new common stock, or uses a third party to purchase shares from the market and deliver such shares for the settlement of the awards. The performance shares granted during 2018 that are earned, have been or will be settled solely in cash. The performance shares granted in 2019 and 2020 that are earned, will be settled in common stock. Stock options, deferred stock units and restricted stock units are settled in common stock. However, for awards that are otherwise settled entirely in common stock, Edison International substitutes cash awards to the extent necessary to satisfy applicable tax withholding obligations or government levies. Stock-based compensation expense is recognized, net of estimated forfeitures, on a straight-line basis over the requisite service period based on estimated fair values. For equity awards paid in common stock, fair value is determined at the grant date. However, with respect to the portion of the performance shares payable in common stock that are subject to market and financial performance conditions defined in the grants, the number of performance shares expected to be earned is subject to revision and updated at each reporting period, with a related adjustment to compensation expense. Awards paid in cash are classified as share-based liability awards and fair value is remeasured at each reporting date with the related compensation cost adjusted. For awards granted to retirement-eligible participants, stock compensation expense is recognized on a prorated basis over the initial year. For awards granted to participants who become eligible for retirement during the requisite service period, stock compensation expense is recognized over the period between the date of grant and the date the participant first becomes eligible for retirement. Edison International and SCE estimate the number of awards that are expected to vest rather than account for forfeitures when they occur. Share-based payments may create a permanent difference between the amount of compensation expense recognized for book and tax purposes. The tax impact of this permanent difference is recognized in earnings in the period it is created. See Note 9 for further information. |
SCE Dividends | SCE Dividends CPUC holding company rules require that SCE's dividend policy be established by SCE's Board of Directors on the same basis as if SCE were a stand-alone utility company, and that the capital requirements of SCE, as deemed to be necessary to meet SCE's electricity service obligations, shall receive first priority from the Boards of Directors of both Edison International and SCE. In addition, the CPUC regulates SCE's capital structure which limits the dividends it may pay to its shareholders. Effective January 1, 2020, the common equity component of SCE's CPUC authorized capital structure was increased from 48% to 52% on a weighted average basis over the January 1, 2020 to December 31, 2022 compliance period. Under AB 1054, the impact of SCE's contributions to the Wildfire Insurance Fund are excluded from the measurement of SCE's CPUC-jurisdictional authorized capital structure. For further information, see Note 12. In May 2020, the CPUC issued a decision on SCE's application to the CPUC for waiver of compliance with its equity ratio requirement, that allows SCE to exclude from its equity ratio calculations (i) net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events and (ii) debt issued for the purpose of paying claims related to the 2017/2018 Wildfire/Mudslide Events up to an amount equal to the net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events. The temporary exclusion will lapse on May 7, 2022 or when a determination regarding cost recovery for the 2017/2018 Wildfire/Mudslide Events is made, whichever comes earlier. If the CPUC has not made a determination regarding cost recovery by May 7, 2022, SCE is permitted to file another application for a waiver of compliance with its equity ratio requirement. In the interim, SCE is required to notify the CPUC if an adverse financial event reduces SCE's spot equity ratio by more than one percent from the level most recently filed with the CPUC in the proceeding. The last spot equity ratio SCE filed with the CPUC in the proceeding did not exclude the then $1.8 billion net charge and was 45.2% as of December 31, 2018 (at the time the common equity component of SCE's CPUC authorized capital structure was required to remain at or above 48% on a weighted average basis over the applicable 37-month period). SCE’s spot equity ratio on December 31, 2018 would have been 48.7% had the $1.8 billion net charge at December 31, 2018 been excluded, therefore SCE will notify the CPUC if its spot ratio drops below 47.7% in any quarter. For further information, see Note 12. SCE monitors its compliance with the CPUC's equity ratio requirement based on the weighted average of the common equity component of SCE's CPUC authorized capital structure over the Capital Structure Compliance Period using its actual capital structure from the beginning of the Capital Structure Compliance Period through the reporting date together with forecasted performance and expected financing activities for the remainder of the Capital Structure Compliance Period. SCE expects to be compliant with its CPUC authorized capital structure at December 31, 2022. As a California corporation, SCE's ability to pay dividends is also governed by the California General Corporation Law. California law requires that for a dividend to be declared: (a) retained earnings must equal or exceed the proposed dividend, or (b) immediately after the dividend is made, the value of the corporation's assets must exceed the value of its liabilities plus amounts required to be paid, if any, in order to liquidate stock senior to the shares receiving the dividend. Additionally, a California corporation may not declare a dividend if it is, or as a result of the dividend would be, likely to be unable to meet its liabilities as they mature. Prior to declaring dividends, SCE's Board of Directors evaluates available information, including when applicable, information pertaining to the 2017/2018 Wildfire/Mudslide Events, to ensure that the California law requirements for the declarations are met. On February 25, 2021, SCE declared a dividend to Edison International of $325 million. The timing and amount of future dividends are also dependent on a number of other factors including SCE's requirements to fund other obligations and capital expenditures, its ability to access the capital markets, and generate operating cash flows and earnings. If SCE incurs significant costs related to catastrophic wildfires, including the 2017/2018 Wildfire/Mudslide Events, and is unable to recover such costs through insurance, the Wildfire Insurance Fund (for fires after July 12, 2019), or from customers or is unable to access capital markets on reasonable terms, SCE may be limited in its ability to pay future dividends to Edison International and its preference shareholders. |
Earnings Per Share | Earnings Per ShareEdison International computes earnings per common share ("EPS") using the two-class method, which is an earnings allocation formula that determines EPS for each class of common stock and participating security. Edison International's participating securities are stock-based compensation awards, payable in common shares, which earn dividend equivalents on an equal basis with common shares once the awards are vested. |
Income Taxes | Income Taxes Edison International and SCE estimate their income taxes for each jurisdiction in which they operate. This involves estimating current period tax expense along with assessing temporary differences resulting from differing treatment of items (such as depreciation) for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in the consolidated balance sheets. Income tax expense includes the current tax liability from operations and the change in deferred income taxes during the year. Interest income, interest expense and penalties associated with income taxes are generally reflected in "Income tax expense" on the consolidated statements of income. Edison International's eligible subsidiaries are included in Edison International's consolidated federal income tax and combined state tax returns. Edison International has tax-allocation and payment agreements with certain of its subsidiaries. Pursuant to an income tax-allocation agreement approved by the CPUC, SCE's tax liability is computed as if it filed its federal and state income tax returns on a separate return basis. |
New Accounting Guidance | New Accounting Guidance Accounting Guidance Adopted In June 2016, the Financial Accounting Standards Board ("FASB") issued an accounting standards update to require the use of the current expected credit loss model to measure impairment of financial assets measured at amortized cost, including trade and other receivables, and the use of an allowance to record estimated credit losses on available-for-sale debt securities. Edison International and SCE adopted this guidance on January 1, 2020 using the prospective adoption approach to available-for-sale debt securities and the modified retrospective approach to all other financial assets. The adoption of this guidance did not have a material impact on Edison International's and SCE's financial position or result of operations. See "Allowance for Uncollectible Accounts" and "Nuclear Decommissioning and Asset Retirement Obligations" above and Note 10 for further information. In August 2018, the FASB issued an accounting standards update which aligns the requirement for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing costs incurred to develop or obtain internal use software. The guidance also clarified presentation requirements for reporting implementation costs in the financial statements. Edison International and SCE adopted the standard on January 1, 2020 using the prospective adoption approach. The adoption of this guidance did not have a material impact on Edison International's and SCE's financial position or result of operations. In March 2020, the FASB issued an accounting standards update to provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference London Inter-Bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued an update to this standard to clarify that certain optional expedients and exceptions for contract modifications and hedge accounting apply to derivatives that are affected by the reference rate transition. Edison International and SCE have adopted the standard as of April 1, 2020 prospectively. SCE generally does not use hedge accounting for derivative transactions. SCE has a term loan with a variable interest rate based on LIBOR. In addition, both Edison International and SCE have revolving credit facilities with a variable interest rate based on LIBOR. These agreements contain provisions that require an amendment if LIBOR can no longer be used. SCE also has certain preference stocks, for which the distributions will be payable at a floating rate referenced to LIBOR from 2022. As of December 31, 2020, both Edison International and SCE have not utilized any of the expedients and therefore there is no impact on adoption of the guidance, however, if contract amendments are made where LIBOR is no longer valid, both Edison International and SCE expect to utilize the expedients through the allowed period of December 31, 2022. In August 2018, the FASB issued an accounting standards update to remove, modify and add certain disclosure requirements related to employer-sponsored defined benefit pension or other postretirement plans. The guidance removes disclosure requirements that are no longer considered cost beneficial, clarifies certain specific disclosure requirements and adds disclosure requirements identified as relevant. The modifications only affect annual period disclosures and must be applied on a retrospective basis to all periods presented. Edison International and SCE have adopted this guidance for the year ending December 31, 2020. The adoption of this guidance did not materially affect the annual disclosures related to employer-sponsored defined benefit pension or other postretirement plans. See Note 9 for further information. Accounting Guidance Not Yet Adopted In August 2020, the FASB issued an accounting standards update to simplify the accounting for certain financial instruments with characteristics of liabilities and equity. The amendments in this update affect entities that issue convertible instruments indexed to or potentially settled in an entity's own equity. This guidance also simplifies an entity's application of the derivatives scope exception for contracts in its own equity and amend s certain aspects of the EPS guidance. The guidance is effective January 1, 2022 with early adoption permitted after January 1, 2021. Edison International and SCE do not expect the adoption of this standard will materially affect Edison International's and SCE's |
