Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies As permitted by the rules and regulations of the SEC, the Companies' accompanying unaudited Consolidated Financial Statements contain certain condensed financial information and exclude certain footnote disclosures normally included in annual audited consolidated financial statements prepared in accordance with GAAP. These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes in the Companies' Annual Report on Form 10-K for the year ended December 31, 2014. In the Companies' opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position as of June 30, 2015, their results of operations for the three and six months ended June 30, 2015 and 2014, and their cash flows for the six months ended June 30, 2015 and 2014. Such adjustments are normal and recurring in nature unless otherwise noted. The Companies make certain estimates and assumptions in preparing their Consolidated Financial Statements in accordance with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the periods presented. Actual results may differ from those estimates. The Companies' accompanying unaudited Consolidated Financial Statements include, after eliminating intercompany transactions and balances, their accounts, those of their respective majority-owned subsidiaries and non-wholly owned entities in which they have a controlling financial interest. For certain partnership structures, income is allocated based on the liquidation value of the underlying contractual arrangements. As of June 30, 2015, Dominion owns the general partner and 70.9% of the limited partner interests in Dominion Midstream. The public’s ownership interest in Dominion Midstream is reflected as noncontrolling interest in Dominion’s Consolidated Financial Statements. Also, as of June 30, 2015, Dominion owns 50% of the units in and consolidates Four Brothers. SunEdison’s ownership interest in Four Brothers is reflected as noncontrolling interest in Dominion’s Consolidated Financial Statements. See Note 3 for more details regarding the nature and purpose of Four Brothers. The results of operations for interim periods are not necessarily indicative of the results expected for the full year. Information for quarterly periods is affected by seasonal variations in sales, rate changes, electric fuel and other energy-related purchases, purchased gas expenses and other factors. Certain amounts in the Companies' 2014 Consolidated Financial Statements and Notes have been reclassified to conform to the 2015 presentation for comparative purposes. The reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows. Amounts disclosed for Dominion are inclusive of Virginia Power and/or Dominion Gas, where applicable.

Business Combinations, Discontinued Operations and Disposal Groups [Abstract]
Acquisitions and Dispositions	Acquisitions and Dispositions Dominion Acquisition of Four Brothers In June 2015, Dominion acquired 50% of the units in Four Brothers from SunEdison for approximately $64 million of consideration, consisting of $2 million in cash and a $62 million payable, which is included in other current liabilities in Dominion's Consolidated Balance Sheets as of June 30, 2015. Four Brothers' purpose is to develop and operate four solar projects located in Utah, which will produce and sell electricity and renewable energy credits. The projects are expected to cost approximately $730 million to construct, including the initial acquisition cost. Dominion is obligated to contribute $445 million of capital to fund the construction of the projects. The facilities are expected to begin commercial operations in the third quarter of 2016, generating approximately 320 MW. Long-term power purchase, interconnection and operation and maintenance agreements have been executed for each of the projects. Dominion expects to claim 99% of the federal investment tax credits on the projects. Dominion owns 50% of the voting interests in Four Brothers and has a controlling financial interest over the entity through its rights to control operations. The allocation of the purchase price resulted in approximately $89 million of property, plant and equipment, $25 million of noncontrolling interest and $64 million of acquired equity. The noncontrolling interest was measured at fair value using the discounted cash flow method, with the primary components of the valuation being future cash flows (both incoming and outgoing) and the discount rate. Dominion determined its discount rate based on the cost of capital a utility-scale investor would expect, as well as the cost of capital an individual project developer could achieve via a combination of non-recourse project financing and outside equity partners. Four Brothers has entered into agreements with SunEdison to provide administrative and support services in connection with the construction of the project, operation and maintenance of the facilities, and administrative and technical management services of the solar facilities. In addition, Dominion has entered into a contract with SunEdison to provide services related to construction project management and oversight. There have been no costs related to services to be provided under these agreements for the six months ended June 30, 2015. Acquisitions of Solar Projects The following table presents other significant acquisitions of solar projects by Dominion in 2014 and 2015. Long-term power purchase, interconnection and operation and maintenance agreements have been executed for all of the projects. Dominion has claimed and/or expects to claim federal investment tax credits on the projects.

(2) The purchase price was primarily allocated to Property, Plant and Equipment. (3) Marin Carport is expected to begin commercial operations in late 2015 or early 2016. (4) The allocation of the purchase price to individual assets is under evaluation by management and has not been finalized. In June 2015, Dominion entered into an agreement to acquire 100% of the equity interests in the Maricopa West solar project in California from EC&R NA Solar PV, LLC for approximately $65 million in cash. The project is expected to close in the fourth quarter of 2015 and cost approximately $66 million once constructed, including the initial acquisition cost. Upon completion, the facility is expected to generate approximately 20 MW. The acquired assets of Four Brothers and the other solar projects are included in the Dominion Generation operating segment. Acquisition of DCGT In January 2015, Dominion completed the acquisition of 100% of the equity interests of DCGT from SCANA Corporation for approximately $497 million in cash, as adjusted for working capital. DCGT owns and operates nearly 1,500 miles of FERC-regulated interstate natural gas pipeline in South Carolina and southeastern Georgia. This acquisition supports Dominion’s natural gas expansion into the Southeast. The allocation of the purchase price is currently being evaluated and has preliminarily resulted in approximately $277 million of net property, plant and equipment, $250 million of goodwill, of which approximately $225 million is expected to be deductible for income tax purposes, and approximately $38 million of regulatory liabilities. The goodwill reflects the value associated with enhancing Dominion's regulated gas position, economic value attributable to future expansion projects as well as increased opportunities for synergies. The acquired assets of DCGT are included in the Dominion Energy operating segment. On March 24, 2015, DCGT converted to a limited liability company under the laws of South Carolina and changed its name from Carolina Gas Transmission Corporation to DCGT. On April 1, 2015, Dominion contributed 100% of the issued and outstanding membership interests of DCGT to Dominion Midstream in exchange for total consideration of $501 million , as adjusted for working capital. Total consideration to Dominion consisted of the issuance of a two -year, approximately $301 million senior unsecured promissory note payable by Dominion Midstream at an annual interest rate of 0.6% , and 5,112,139 common units, valued at $200 million , representing limited partner interests in Dominion Midstream. The number of units was based on the volume weighted average trading price of Dominion Midstream's common units for the ten trading days prior to April 1, 2015, or $39.12 per unit. Since Dominion consolidates Dominion Midstream for financial reporting purposes, this transaction was eliminated upon consolidation and did not impact Dominion's financial position or cash flows. Sale of Electric Retail Energy Marketing Business In March 2014, Dominion completed the sale of its electric retail energy marketing business. The proceeds were approximately $187 million , net of transaction costs. The sale resulted in a gain, subject to post-closing adjustments, of approximately $100 million ( $57 million after-tax) net of a $31 million write-off of goodwill, and is included in other operations and maintenance expense in Dominion's Consolidated Statements of Income. The sale of the electric retail energy marketing business did not qualify for discontinued operations classification. Dominion Gas Assignments of Marcellus Acreage In December 2013, DTI closed an agreement with a natural gas producer to convey over time approximately 79,000 acres of Marcellus Shale development rights underneath one of its natural gas storage fields. The agreement provided for payments to DTI, subject to customary adjustments, of up to approximately $200 million over a period of nine years, and an overriding royalty interest in gas produced from the acreage. In 2013 and 2014, DTI received approximately $98 million in cash proceeds. At December 31, 2014, deferred revenue totaled approximately $85 million . In March 2015, DTI and the natural gas producer closed on an amendment to the agreement, which included the immediate conveyance of approximately 9,000 acres of Marcellus Shale development rights and a two year extension of the term of the original agreement. The conveyance of development rights resulted in the recognition of $43 million ( $27 million after-tax) of previously deferred revenue to operations and maintenance expense in Dominion Gas' Consolidated Statements of Income. At June 30, 2015, deferred revenue totaled approximately $38 million , which is expected to be recognized over the remaining term of the agreement. In March 2015, DTI conveyed to a natural gas producer approximately 11,000 acres of Marcellus Shale development rights underneath one of its natural gas storage fields and received proceeds of approximately $27 million and an overriding royalty interest in gas produced from the acreage. This transaction resulted in a $27 million ( $16 million after-tax) gain, included in other operations and maintenance expense in Dominion Gas' Consolidated Statements of Income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Companies' fair value measurements are made in accordance with the policies discussed in Note 6 to the Consolidated Financial Statements in the Companies' Annual Report on Form 10-K for the year ended December 31, 2014. See Note 9 in this report for further information about the Companies' derivatives and hedge accounting activities. The Companies enter into certain physical and financial forwards, futures, options and swaps, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical and financial forwards and futures contracts. An option model is used to value Level 3 physical and financial options. The discounted cash flow model for forwards and futures calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return, and credit spreads. The option model calculates mark-to-market valuations using variations of the Black-Scholes option model. The inputs into the models are the forward market prices, implied price volatilities, risk-free rate of return, the option expiration dates, the option strike prices, the original sales prices, and volumes. For Level 3 fair value measurements, forward market prices, credit spreads and implied price volatilities are considered unobservable. The unobservable inputs are developed and substantiated using historical information, available market data, third-party data, and statistical analysis. Periodically, inputs to valuation models are reviewed and revised as needed, based on historical information, updated market data, market liquidity and relationships, and changes in third-party pricing sources. The following table presents Dominion's quantitative information about Level 3 fair value measurements at June 30, 2015. The range and weighted average are presented in dollars for market price inputs and percentages for credit spreads and price volatility.

Fair Value of Financial Instruments Substantially all of the Companies' financial instruments are recorded at fair value, with the exception of the instruments described below, which are reported at historical cost. Estimated fair values have been determined using available market information and valuation methodologies considered appropriate by management. The carrying amount of cash and cash equivalents, restricted cash (which is recorded in other current assets), customer and other receivables, short-term debt, affiliated current borrowings, payables to affiliates and accounts payable are representative of fair value because of the short-term nature of these instruments. For the Companies' financial instruments that are not recorded at fair value, the carrying amounts and estimated fair values are as follows: June 30, 2015 December 31, 2014 Carrying Estimated Fair (1) Carrying Estimated Fair (1) (millions) Dominion Long-term debt, including securities due within one year (2)(3) $ 20,907 $ 22,251 $ 19,723 $ 21,881 Junior subordinated notes (3) 1,373 1,348 1,374 1,396 Remarketable subordinated notes (3) 2,084 2,116 2,083 2,362 Virginia Power Long-term debt, including securities due within one year (3) $ 9,630 $ 10,541 $ 8,937 $ 10,293 Dominion Gas Long-term debt (3) $ 2,594 $ 2,614 $ 2,594 $ 2,672 (1) Fair value is estimated using market prices, where available, and interest rates currently available for issuance of debt with similar terms and remaining maturities. All fair value measurements are classified as Level 2. The carrying amount of debt issues with short-term maturities and variable rates refinanced at current market rates is a reasonable estimate of their fair value. (2) At June 30, 2015 and December 31, 2014, includes the valuation of certain fair value hedges associated with fixed rate debt of approximately $8 million and $ 19 million , respectively. (3) Carrying amount includes amounts which represent the unamortized discount and/or premium.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedge Accounting Activities	Derivatives and Hedge Accounting Activities The Companies' accounting policies and objectives and strategies for using derivative instruments are discussed in Note 2 to the Consolidated Financial Statements in the Companies' Annual Report on Form 10-K for the year ended December 31, 2014. See Note 8 in this report for further information about fair value measurements and associated valuation methods for derivatives. Derivative assets and liabilities are presented gross on the Companies' Consolidated Balance Sheets. Dominion's derivative contracts include both over-the-counter transactions and those that are executed on an exchange or other trading platform (exchange contracts) and centrally cleared. Dominion Gas' and Virginia Power's derivative contracts consist of over-the-counter transactions. Over-the-counter contracts are bilateral contracts that are transacted directly with a counterparty. Exchange contracts utilize a financial intermediary, exchange, or clearinghouse to enter, execute, or clear the transactions. Certain over-the-counter and exchange contracts contain contractual rights of setoff through master netting arrangements, derivative clearing agreements, and contract default provisions. In addition, the contracts are subject to conditional rights of setoff through counterparty nonperformance, insolvency, or other conditions. In general, most over-the-counter transactions and all exchange contracts are subject to collateral requirements. Types of collateral for over-the-counter and exchange contracts include cash, letters of credit, and in some cases other forms of security, none of which are subject to restrictions. Cash collateral is used in the table below to offset derivative assets and liabilities. Certain accounts receivable and accounts payable recognized on the Companies' Consolidated Balance Sheets, as well as letters of credit and other forms of security, all of which are not included in the tables below, are subject to offset under master netting or similar arrangements and would reduce the net exposure. Dominion Balance Sheet Presentation The tables below present Dominion's derivative asset and liability balances by type of financial instrument, before and after the effects of offsetting: June 30, 2015 December 31, 2014 Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheet Net Amounts of Assets Presented in the Consolidated Balance Sheet Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheet Net Amounts of Assets Presented in the Consolidated Balance Sheet (millions) Interest rate contracts: Over-the-counter $ 58 $ — $ 58 $ 24 $ — $ 24 Commodity contracts: Over-the-counter 276 — 276 382 — 382 Exchange 253 — 253 298 — 298 Total derivatives, subject to a master netting or similar arrangement 587 — 587 704 — 704 Total derivatives, not subject to a master netting or similar arrangement 10 — 10 15 — 15 Total $ 597 $ — $ 597 $ 719 $ — $ 719 June 30, 2015 December 31, 2014 Gross Amounts Not Offset in the Consolidated Balance Sheet Gross Amounts Not Offset in the Consolidated Balance Sheet Net Amounts of Assets Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Received Net Amounts Net Amounts of Assets Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Received Net Amounts (millions) Interest rate contracts: Over-the-counter $ 58 $ 25 $ — $ 33 $ 24 $ 16 $ — $ 8 Commodity contracts: Over-the-counter 276 30 17 229 382 34 34 314 Exchange 253 247 — 6 298 298 — — Total $ 587 $ 302 $ 17 $ 268 $ 704 $ 348 $ 34 $ 322 June 30, 2015 December 31, 2014 Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Consolidated Balance Sheet Net Amounts of Liabilities Presented in the Consolidated Balance Sheet Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Consolidated Balance Sheet Net Amounts of Liabilities Presented in the Consolidated Balance Sheet (millions) Interest rate contracts: Over-the-counter $ 108 $ — $ 108 $ 202 $ — $ 202 Commodity contracts: Over-the-counter 65 — 65 87 — 87 Exchange 272 — 272 493 — 493 Total derivatives, subject to a master netting or similar arrangement 445 — 445 782 — 782 Total derivatives, not subject to a master netting or similar arrangement 8 — 8 12 — 12 Total $ 453 $ — $ 453 $ 794 $ — $ 794 June 30, 2015 December 31, 2014 Gross Amounts Not Offset in the Consolidated Balance Sheet Gross Amounts Not Offset in the Consolidated Balance Sheet Net Amounts of Liabilities Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Paid Net Amounts Net Amounts of Liabilities Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Paid Net Amounts (millions) Interest rate contracts: Over-the-counter $ 108 $ 25 $ — $ 83 $ 202 $ 16 $ — $ 186 Commodity contracts: Over-the-counter 65 30 — 35 87 34 1 52 Exchange 272 247 25 — 493 298 195 — Total $ 445 $ 302 $ 25 $ 118 $ 782 $ 348 $ 196 $ 238 Volumes The following table presents the volume of Dominion’s derivative activity as of June 30, 2015.

Equity Method Investments Dominion Gas Dominion Gas accounts for the following investment under the equity method of accounting: Company Ownership% Investment Balance Description June 30, 2015 December 31, 2014 (millions) Iroquois 24.72 % $ 107 $ 107 Gas transmission system Total $ 107 $ 107 Dominion Gas' equity earnings on this investment totaled $12 million and $13 million for the six months ended June 30, 2015 and 2014, respectively. Dominion Gas received distributions from this investment of $12 million and $5 million for the six months ended June 30, 2015 and 2014, respectively. As of June 30, 2015 and December 31, 2014, the carrying amount of Dominion Gas' investment exceeded its share of underlying equity in net assets by approximately $8 million . The differences reflect equity method goodwill and are not being amortized. Dominion and Dominion Gas Blue Racer In December 2012, Dominion formed Blue Racer with Caiman to provide midstream services to natural gas producers operating in the Utica Shale region in Ohio and portions of Pennsylvania. Blue Racer is an equal partnership between Dominion and Caiman, with Dominion contributing midstream assets and Caiman contributing private equity capital. Dominion NGL Pipelines, LLC was contributed in January 2014 by Dominion to Blue Racer, prior to commencement of service, resulting in an increased equity method investment of $155 million , including $6 million of goodwill allocated from Dominion's goodwill balance to its equity method investment in Blue Racer. In March 2014, Dominion Gas sold the Northern System to an affiliate, that subsequently sold the Northern System to Blue Racer for consideration of approximately $84 million . Dominion Gas' consideration consisted of $17 million in cash proceeds and the extinguishment of affiliated long-term debt of $67 million and Dominion's consideration consisted of cash proceeds of approximately $84 million . The sale resulted in a gain of approximately $59 million ( $35 million after-tax for Dominion Gas and $34 million after-tax for Dominion) net of a $3 million write-off of goodwill, and is included in other operations and maintenance expense in both Dominion Gas' and Dominion's Consolidated Statements of Income.

(7) Amounts to be recovered through future rates to pay income taxes that become payable when rate revenue is provided to recover AFUDC-equity and depreciation of property, plant and equipment for which deferred income taxes were not recognized for ratemaking purposes, including amounts attributable to tax rate changes. (8) For jurisdictions subject to cost-based rate regulation, changes in the fair value of derivative instruments result in the recognition of regulatory assets or regulatory liabilities as they are expected to be recovered from or passed on to customers based on the ultimate settlement amount of the derivative. (9) Under PIPP, eligible customers can make reduced payments based on their ability to pay. The difference between the customer's total bill and the PIPP plan amount is deferred and collected or returned annually under the PIPP rider according to East Ohio tariff provisions. (10) Current regulatory liabilities are presented in other current liabilities in the Companies' Consolidated Balance Sheets. (11) Rates charged to customers by the Companies' regulated businesses include a provision for the cost of future activities to remove assets that are expected to be incurred at the time of retirement.

Regulatory Matters [Abstract]
Regulatory Matters	Regulatory Matters Regulatory Matters Involving Potential Loss Contingencies As a result of issues generated in the ordinary course of business, the Companies are involved in various regulatory matters. Certain regulatory matters may ultimately result in a loss; however, as such matters are in an initial procedural phase, involve uncertainty as to the outcome of pending reviews or orders, and/or involve significant factual issues that need to be resolved, it is not possible for the Companies to estimate a range of possible loss. For matters for which the Companies cannot estimate a range of possible loss, a statement to this effect is made in the description of the matter. Other matters may have progressed sufficiently through the regulatory process such that the Companies are able to estimate a range of possible loss. For regulatory matters for which the Companies are able to reasonably estimate a range of possible losses, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. Any estimated range is based on currently available information, involves elements of judgment and significant uncertainties and may not represent the Companies' maximum possible loss exposure. The circumstances of such regulatory matters will change from time to time and actual results may vary significantly from the current estimate. For current matters not specifically reported below, management does not anticipate that the outcome from such matters would have a material effect on the Companies' financial position, liquidity or results of operations. FERC - Electric Under the Federal Power Act, FERC regulates wholesale sales and transmission of electricity in interstate commerce by public utilities. Dominion's merchant generators sell electricity in the PJM, MISO, CAISO and ISO-NE wholesale markets, and to wholesale purchasers in the states of Tennessee, Georgia and California under Dominion's market-based sales tariffs authorized by FERC. Virginia Power purchases and, under its FERC market-based rate authority, sells electricity in the wholesale market. In addition, Virginia Power has FERC approval of a tariff to sell wholesale power at capped rates based on its embedded cost of generation. This cost-based sales tariff could be used to sell to loads within or outside Virginia Power's service territory. Any such sales would be voluntary. Rates In April 2008, FERC granted an application for Virginia Power's electric transmission operations to establish a forward-looking formula rate mechanism that updates transmission rates on an annual basis and approved an ROE of 11.4% , effective as of January 1, 2008. The formula rate is designed to recover the expected revenue requirement for each calendar year and is updated based on actual costs. The FERC-approved formula method, which is based on projected costs, allows Virginia Power to earn a current return on its growing investment in electric transmission infrastructure. In March 2010, ODEC and NCEMC filed a complaint with FERC against Virginia Power claiming that approximately $223 million in transmission costs related to specific projects were unjust, unreasonable and unduly discriminatory or preferential and should be excluded from Virginia Power's transmission formula rate. In October 2010, FERC issued an order dismissing the complaint in part and established hearings and settlement procedures on the remaining part of the complaint. In February 2012, Virginia Power submitted to FERC a settlement agreement to resolve all issues set for hearing. The settlement was accepted by FERC in May 2012 and provides for payment by Virginia Power to the transmission customer parties collectively of $250,000 per year for ten years and resolves all matters other than allocation of the incremental cost of certain underground transmission facilities. In March 2014, FERC issued an order excluding from Virginia Power’s transmission rates for wholesale transmission customers located outside Virginia the incremental costs of undergrounding certain transmission line projects. FERC found it is not just and reasonable for non-Virginia wholesale transmission customers to be allocated the incremental costs of undergrounding the facilities because the projects are a direct result of Virginia legislation and Virginia Commission pilot programs intended to benefit the citizens of Virginia. The order is retroactively effective as of March 2010 and will cause the reallocation of the costs charged to wholesale transmission customers with loads outside Virginia to wholesale transmission customers with loads in Virginia. FERC determined that there was not sufficient evidence on the record to determine the magnitude of the underground increment and ordered a hearing to determine the appropriate amount of undergrounding cost to be allocated to each wholesale transmission customer in Virginia. While Virginia Power cannot predict the outcome of the hearing, it is not expected to have a material effect on results of operations. PJM Transmission Rates In April 2007, FERC issued an order regarding its transmission rate design for the allocation of costs among PJM transmission customers, including Virginia Power, for transmission service provided by PJM. For new PJM-planned transmission facilities that operate at or above 500 kV, FERC established a PJM regional rate design where customers pay according to each customer's share of the region's load. For recovery of costs of existing facilities, FERC approved the existing methodology whereby a customer pays the cost of facilities located in the same zone as the customer. A number of parties appealed the order to the U.S. Court of Appeals for the Seventh Circuit. In August 2009, the court issued its decision affirming the FERC order with regard to the existing facilities, but remanded to FERC the issue of the cost allocation associated with the new facilities 500 kV and above for further consideration by FERC. On remand, FERC reaffirmed its earlier decision to allocate the costs of new facilities 500 kV and above according to the customer’s share of the region’s load. A number of parties filed appeals of the order to the U.S. Court of Appeals for the Seventh Circuit. In June 2014, the court again remanded the cost allocation issue to FERC. In December 2014, FERC issued an order setting an evidentiary hearing and settlement proceeding regarding the cost allocation issue. The hearing only concerns the costs of new facilities approved by PJM prior to February 1, 2013. Transmission facilities approved after February 1, 2013 are allocated on a hybrid cost allocation method approved by FERC and not subject to any court review. Settlement discussions are ongoing. Virginia Power anticipates that the majority of the impacts of any rate design changes resulting from the settlement discussions will be recoverable through retail rates in Virginia. Other Regulatory Matters Other than the following matters, there have been no significant developments regarding the pending regulatory matters disclosed in Note 13 to the Consolidated Financial Statements in the Companies' Annual Report on Form 10-K for the year ended December 31, 2014 and Note 12 to the Consolidated Financial Statements in the Companies’ Quarterly Report on Form 10-Q for the quarter ended March 31, 2015. Virginia Regulation Rate Adjustment Clauses Below is a discussion of significant riders associated with various Virginia Power projects: • The Virginia Commission previously approved Rider T1 concerning transmission rates. In May 2015, Virginia Power proposed an approximately $668 million total revenue requirement for the rate year beginning September 1, 2015, which represents an approximately $130 million increase over the previous year. Virginia Power also presented a mitigation proposal to defer approximately $96 million of this revenue requirement to the rate year beginning September 1, 2016, which would reduce by 50% the one -year rate impact on residential customers. In August 2015, the Virginia Commission rejected the mitigation proposal and approved full recovery of the proposed revenue requirement. • The Virginia Commission previously approved Rider S in conjunction with the Virginia City Hybrid Energy Center. In June 2015, Virginia Power proposed an approximately $250 million revenue requirement for the rate year beginning April 1, 2016, which represents an approximately $5 million increase over the previous year. This case is pending. • The Virginia Commission previously approved Rider W in conjunction with Warren County. In June 2015, Virginia Power proposed an approximately $118 million revenue requirement for the rate year beginning April 1, 2016, which represents an approximately $17 million decrease versus the previous year. This case is pending. • The Virginia Commission previously approved Rider R in conjunction with Bear Garden. In June 2015, Virginia Power proposed an approximately $74 million revenue requirement for the rate year beginning April 1, 2016, which represents an approximately $10 million decrease versus the previous year. This case is pending. • The Virginia Commission previously approved Rider B in conjunction with the conversion of three power stations to biomass. In June 2015, Virginia Power proposed an approximately $30 million revenue requirement for the rate year beginning April 1, 2016, which represents an approximately $21 million increase over the previous year. This case is pending. • Virginia legislation which provides for the recovery of costs to move certain electric distribution facilities underground became effective in July 2014. In October 2014, Virginia Power filed for approval of Rider U, which proposed a revenue requirement of approximately $28 million during the initial rate year beginning September 1, 2015. In May 2015, Virginia Power revised the revenue requirement to $24 million . In July 2015, the Virginia Commission denied approval of Rider U based on the evidence in the record, but found that an alternative plan addressing certain concerns they had, such as the lack of a cost benefit analysis, could reasonably satisfy the regulatory requirements for approval. Virginia Power is reviewing the order and assessing its options, which could include filing such an alternative plan by year end. Electric Transmission Project In April 2015, the Supreme Court of Virginia issued its opinion in the consolidated appeals of the Virginia Commission’s order granting a CPCN for the Skiffes Creek transmission line and related facilities. The Supreme Court of Virginia unanimously affirmed all but one of the alleged grounds for appeal. The court approved the proposed project including the proposed route for a 500 kV overhead transmission line from Surry Power Station to the Skiffes Creek Switching Station site. The court reversed and remanded the Virginia Commission’s determination in one set of appeals that the Skiffes Creek Switching Station was a transmission line for purposes of statutory exemption from local zoning ordinances. In May 2015, the Supreme Court of Virginia denied separate petitions filed by Virginia Power and the Virginia Commission to rehear its ruling regarding the Skiffes Creek Switching Station. Pending receipt of remaining required permits and approvals, Virginia Power expects to construct the project. North Anna Virginia Power is considering the construction of a third nuclear unit at a site located at North Anna. If Virginia Power decides to build a new unit, it must first receive a COL from the NRC, approval of the Virginia Commission and certain environmental permits and other approvals. The COL is expected as early as 2016. Virginia Power has not yet committed to building a new nuclear unit at North Anna. In September 2014, BREDL filed a petition with the NRC again seeking suspension of final decision making in the COL proceeding, along with motions to reopen and file a new contention. BREDL asserted that the NRC must make a safety finding on the feasibility and capacity of geologic disposal of spent fuel prior to the issuance of a license. BREDL also alleged that because these safety findings are no longer made as part of the NRC’s new continued storage rule, such findings must now be made in individual licensing proceedings. In January 2015, BREDL filed another petition asking the NRC to supplement the final environmental impact statement for North Anna 3 to incorporate the NRC’s generic assessment of the impacts of continued spent fuel storage, which would allow BREDL to then challenge that assessment. The NRC denied the September 2014 petition and motions filed by BREDL in February 2015 and the January 2015 petition filed by BREDL in April 2015. In April 2015, BREDL filed a new motion and petition seeking to object to the NRC’s reliance on the continued storage rule in licensing proceedings. The BREDL filings are substantially the same as those filed in other COL proceedings in which final environmental impact statements were issued prior to promulgation of the continued storage rule, like North Anna 3. In June 2015, the NRC denied the April 2015 motion and petition. In April 2014 legislation was enacted in Virginia that permits Virginia Power to recover 70% of the costs previously deferred or capitalized related to the development of a third nuclear unit located at North Anna and offshore wind facilities through December 31, 2013 as part of the 2013 and 2014 base rates. In the second quarter of 2014, Virginia Power recognized a $287 million ( $191 million after-tax) charge against income representing the cumulative recovery of costs from January 2013 through June 2014 and recognized additional charges of approximately $87 million ( $57 million after-tax) ratably during the remainder of 2014, which are primarily included in other operations and maintenance expense in the Consolidated Statements of Income. The remaining deferred or capitalized costs, as well as costs incurred after December 31, 2013, continue to be eligible for inclusion in a future rate adjustment clause. North Carolina Regulation In December 2012, the North Carolina Commission decided Virginia Power’s general rate case filed earlier that year, authorizing a 10.2% ROE. Following an appeal to the Supreme Court of North Carolina by multiple parties and a remand, the North Carolina Commission issued an opinion in July 2015 reaffirming its 10.2% ROE determination. Ohio Regulation PIPP Rider Under the Ohio PIPP Plus Program, eligible customers can make reduced payments based on their ability to pay their bill. The difference between the customer’s total bill and the PIPP amount is deferred and collected under the PIPP Rider in accordance with the rules of the Ohio Commission. In July 2015, East Ohio’s annual update of the PIPP Rider was automatically approved by the Ohio Commission after a 45-day waiting period from the date of the filing. The revised rider rate reflects the refund for the twelve-month period from July 2015 through June 2016 of an over-recovery of accumulated arrearages of approximately $57 million as of March 31, 2015, net of projected deferred program costs of approximately $35 million from April 2015 through June 2016. UEX Rider East Ohio has approval for a UEX Rider through which it recovers the bad debt expense of most customers not participating in the PIPP Plus Program. The UEX Rider is adjusted annually to achieve dollar for dollar recovery of East Ohio’s actual write-offs of uncollectible amounts. In July 2015, the Ohio Commission approved East Ohio's application to decrease its UEX Rider, which reflects a refund of over-recovered accumulated bad debt expense of approximately $14 million as of March 31, 2015, and recovery of prospective net bad debt expense projected to total approximately $20 million for the twelve-month period from April 2015 to March 2016.

Asset Retirement Obligation Disclosure [Abstract]
Asset Retirement Obligations	Asset Retirement Obligations AROs represent obligations that result from laws, statutes, contracts and regulations related to the eventual retirement of certain of the Companies' long-lived assets. Dominion’s and Virginia Power’s AROs are primarily associated with the decommissioning of their nuclear generation facilities and also include those for ash pond closures and the future abatement of asbestos expected to be disturbed in their generation facilities. Dominion Gas' AROs primarily include plugging and abandonment of gas and oil wells and the interim retirement of natural gas gathering, transmission, distribution and storage pipeline components. The Companies have also identified, but not recognized, AROs related to retirement of Dominion’s LNG facility, Dominion Gas' storage wells in its underground natural gas storage network, certain Virginia Power electric transmission and distribution assets located on property with easements, rights of way, franchises and lease agreements, Virginia Power’s hydroelectric generation facilities and the abatement of certain asbestos not expected to be disturbed in Dominion's and Virginia Power's generation facilities. The Companies currently do not have sufficient information to estimate a reasonable range of expected retirement dates for any of these assets since the economic lives of these assets can be extended indefinitely through regular repair and maintenance and they currently have no plans to retire or dispose of any of these assets. As a result, a settlement date is not determinable for these assets and AROs for these assets will not be reflected in the Consolidated Financial Statements until sufficient information becomes available to determine a reasonable estimate of the fair value of the activities to be performed. The Companies continue to monitor operational and strategic developments to identify if sufficient information exists to reasonably estimate a retirement date for these assets. The changes to AROs for Dominion and Virginia Power during 2014 and 2015 are presented below. There were no significant changes to Dominion Gas' AROs. Amount (millions) Dominion AROs at December 31, 2013 (1) $ 1,578 Obligations incurred during the period 40 Obligations settled during the period (82 ) Revisions in estimated cash flows (2) 102 Accretion 81 Other (5 ) AROs at December 31, 2014 (1) $ 1,714 Obligations incurred during the period (3) 306 Obligations settled during the period (38 ) Revisions in estimated cash flows (3) 34 Accretion 44 Other (1 ) AROs at June 30, 2015 (1) $ 2,059 Virginia Power AROs at December 31, 2013 $ 689 Obligations incurred during the period 28 Obligations settled during the period (1 ) Revisions in estimated cash flows (2) 108 Accretion 37 Other (6 ) AROs at December 31, 2014 (4) $ 855 Obligations incurred during the period (3) 288 Obligations settled during the period (2 ) Revisions in estimated cash flows (3) 34 Accretion 23 AROs at June 30, 2015 (4) $ 1,198 (1) Includes $94 million , $81 million and $247 million reported in other current liabilities at December 31, 2013, December 31, 2014 and June 30, 2015, respectively. (2) Relates primarily to a shift of the delayed planned date on which the DOE is expected to begin accepting spent nuclear fuel. (3) Primarily reflects future ash pond and landfill closure costs at certain utility generation facilities. See Note 16 for further information. (4) Includes $7 million and $180 million reported in other current liabilities at December 31, 2014 and June 30, 2015, respectively. Dominion and Virginia Power have established trusts dedicated to funding the future decommissioning of their nuclear plants. At June 30, 2015 and December 31, 2014, the aggregate fair value of Dominion’s trusts, consisting primarily of equity and debt securities, totaled $4.2 billion . At June 30, 2015 and December 31, 2014, the aggregate fair value of Virginia Power’s trusts, consisting primarily of debt and equity securities, totaled $1.9 billion .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities As discussed in Note 15 to the Consolidated Financial Statements in the Companies' Annual Report on Form 10-K for the year ended December 31, 2014, certain variable pricing terms in some of the Companies’ contracts cause them to be considered variable interests in the counterparties. Virginia Power Virginia Power has long-term power and capacity contracts with five non-utility generators with an aggregate summer generation capacity of approximately 870 MW. These contracts contain certain variable pricing mechanisms in the form of partial fuel reimbursement that Virginia Power considers to be variable interests. After an evaluation of the information provided by these entities, Virginia Power was unable to determine whether they were VIEs. However, the information they provided, as well as Virginia Power's knowledge of generation facilities in Virginia, enabled Virginia Power to conclude that, if they were VIEs, it would not be the primary beneficiary. This conclusion reflects Virginia Power's determination that its variable interests do not convey the power to direct the most significant activities that impact the economic performance of the entities during the remaining terms of Virginia Power's contracts and for the years the entities are expected to operate after its contractual relationships expire. The contracts expire at various dates ranging from 2015 to 2021 . Virginia Power is not subject to any risk of loss from these potential VIEs other than its remaining purchase commitments which totaled $530 million as of June 30, 2015. Virginia Power paid $56 million and $55 million for electric capacity and $23 million and $33 million for electric energy to these entities in the three months ended June 30, 2015 and 2014, respectively. Virginia Power paid $108 million and $111 million for electric capacity and $60 million and $87 million for electric energy to these entities in the six months ended June 30, 2015 and 2014, respectively. Virginia Power and Dominion Gas Virginia Power and Dominion Gas purchased shared services from DRS, an affiliated VIE, of approximately $83 million and $30 million for the three months ended June 30, 2015, $106 million and $26 million for the three months ended June 30, 2014, $166 million and $58 million for the six months ended June 30, 2015, and $214 million and $52 million for the six months ended June 30, 2014, respectively. Virginia Power and Dominion Gas determined that each is not the most closely associated entity with DRS and therefore neither is the primary beneficiary. DRS provides accounting, legal, finance and certain administrative and technical services to all Dominion subsidiaries, including Virginia Power and Dominion Gas. Virginia Power and Dominion Gas have no obligation to absorb more than their allocated shares of DRS costs.

Debt Disclosure [Abstract]
Significant Financing Transactions	Significant Financing Transactions Credit Facilities and Short-term Debt The Companies use short-term debt to fund working capital requirements and as a bridge to long-term debt financings. The levels of borrowing may vary significantly during the course of the year, depending upon the timing and amount of cash requirements not satisfied by cash from operations. In addition, Dominion utilizes cash and letters of credit to fund collateral requirements. Collateral requirements are impacted by commodity prices, hedging levels, Dominion’s credit ratings and the credit quality of its counterparties. Dominion At June 30, 2015, Dominion’s commercial paper and letters of credit outstanding, as well as its capacity available under credit facilities, were as follows: Facility Outstanding Outstanding Facility (millions) Joint revolving credit facility (1) $ 4,000 $ 2,622 $ — $ 1,378 Joint revolving credit facility (2) 500 — 56 444 Total $ 4,500 $ 2,622 $ 56 $ 1,822 (1) This credit facility has a maturity date of April 2019, and can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $1.5 billion of letters of credit. (2) This credit facility has a maturity date of April 2019, and can be used to support bank borrowings, commercial paper and letter of credit issuances. Virginia Power Virginia Power’s short-term financing is supported by two joint revolving credit facilities with Dominion and Dominion Gas. These credit facilities are being used for working capital, as support for the combined commercial paper programs of the Companies and for other general corporate purposes. At June 30, 2015, Virginia Power’s share of commercial paper and letters of credit outstanding, as well as its capacity available under its joint credit facilities with Dominion and Dominion Gas, were as follows: Facility Sub-limit Outstanding Commercial Paper Outstanding Letters of Credit Facility Sub-limit Capacity Available (millions) Joint revolving credit facility (1) $ 1,500 $ 1,441 $ — $ 59 Joint revolving credit facility (2) 250 — — 250 Total $ 1,750 $ 1,441 $ — $ 309 (1) This credit facility has a maturity date of April 2019, and can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $1.5 billion (or the sub-limit, whichever is less) of letters of credit. Virginia Power's current sub-limit under this credit facility can be increased or decreased multiple times per year. In January 2015, Virginia Power increased its sub-limit from $1.25 billion to $1.50 billion . (2) This credit facility has a maturity date of April 2019, and can be used to support bank borrowings, commercial paper and letter of credit issuances. Virginia Power's current sub-limit under this credit facility can be increased or decreased multiple times per year. In addition to the credit facility commitments mentioned above, Virginia Power also has a $120 million credit facility with a maturity date of April 2019. As of June 30, 2015, this facility supports approximately $119 million of certain variable rate tax-exempt financings of Virginia Power. Dominion Gas Dominion Gas’ short-term financing is supported by the two joint revolving credit facilities discussed above with Dominion and Virginia Power, to which Dominion Gas was added as a borrower in May 2014. In December 2014, Dominion Gas entered into a commercial paper program pursuant to which it began accessing the commercial paper markets in January 2015. At June 30, 2015, Dominion Gas' share of commercial paper and letters of credit outstanding, as well as its capacity available under its joint credit facilities with Dominion and Virginia Power were as follows: Facility Sub-limit Outstanding Commercial Paper Outstanding Letters of Credit Facility Sub-limit Capacity Available (millions) Joint revolving credit facility (1) $ 500 $ 360 $ — $ 140 Joint revolving credit facility (2) — — — — Total $ 500 $ 360 $ — $ 140 (1) This credit facility has a maturity date of April 2019, and can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $1.5 billion (or the sub-limit, whichever is less) of letters of credit. Dominion Gas' current sub-limit under this credit facility can be increased or decreased multiple times per year, up to a maximum of $1.0 billion . (2) This credit facility has a maturity date of April 2019, and can be used to support bank borrowings, commercial paper and letter of credit issuances. Dominion Gas' current sub-limit under this credit facility can be increased or decreased multiple times per year. Long-term Debt In May 2015, Virginia Power issued $350 million of 3.10% senior notes and $350 million of 4.20% senior notes that mature in 2025, and 2045, respectively. In June 2015, Dominion issued $500 million of 1.90% senior notes that mature in 2018. At the option of holders, $510 million of Dominion’s 5.25% senior notes due 2033 are subject to redemption at 100% of the principal amount plus accrued interest in August 2015. As a result, at December 31, 2014, the notes were included in securities due within one year in Dominion's Consolidated Balance Sheets. The option to redeem the notes expired in June 2015. As of June 30, 2015, the notes were reclassified to long-term debt in Dominion's Consolidated Balance Sheets. Issuance of Common Stock Dominion maintains Dominion Direct® and a number of employee savings plans through which contributions may be invested in Dominion’s common stock. These shares may either be newly issued or purchased on the open market with proceeds contributed to these plans. In January 2014, Dominion began purchasing its common stock on the open market for these plans. In April 2014, Dominion began issuing new common shares for these direct stock purchase plans. In December 2014, Dominion filed an SEC shelf registration for the sale of debt and equity securities including the ability to sell common stock through an at-the-market program. Also in December 2014, Dominion entered into four separate sales agency agreements to effect sales under the program and pursuant to which it may offer from time to time up to $500 million aggregate amount of its common stock. Sales of common stock can be made by means of privately negotiated transactions, as transactions on the NYSE at market prices or in such other transactions as are agreed upon by Dominion and the sales agents and in conformance with applicable securities laws. During the first quarter of 2015, Dominion provided sales instructions to the sales agents and issued 2.9 million shares through at-the-market issuances and received cash proceeds of approximately $219 million , net of fees and commissions paid of approximately $2 million . During the second quarter of 2015, Dominion provided sales instructions to the sales agents and issued 1.1 million shares through at-the-market issuances and received cash proceeds of approximately $78 million , net of fees and commissions paid of approximately $1 million . Following these issuances, Dominion has the ability to issue up to approximately $200 million of stock under the 2014 sales agency agreements. However, Dominion completed its 2015 planned market issuances of equity with the issuance of 2.8 million shares and receipt of proceeds of approximately $202 million through a registered underwritten public offering. Dominion has no current plans to issue to the market any additional shares of its common stock or other equity-linked securities in 2015.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies As a result of issues generated in the ordinary course of business, the Companies are involved in legal proceedings before various courts and are periodically subject to governmental examinations (including by regulatory authorities), inquiries and investigations. Certain legal proceedings and governmental examinations involve demands for unspecified amounts of damages, are in an initial procedural phase, involve uncertainty as to the outcome of pending appeals or motions, or involve significant factual issues that need to be resolved, such that it is not possible for the Companies to estimate a range of possible loss. For such matters for which the Companies cannot estimate a range of possible loss, a statement to this effect is made in the description of the matter. Other matters may have progressed sufficiently through the litigation or investigative processes such that the Companies are able to estimate a range of possible loss. For legal proceedings and governmental examinations for which the Companies are able to reasonably estimate a range of possible losses, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. Any accrued liability is recorded on a gross basis with a receivable also recorded for any probable insurance recoveries. Estimated ranges of loss are inclusive of legal fees and net of any anticipated insurance recoveries. Any estimated range is based on currently available information and involves elements of judgment and significant uncertainties. Any estimated range of possible loss may not represent the Companies' maximum possible loss exposure. The circumstances of such legal proceedings and governmental examinations will change from time to time and actual results may vary significantly from the current estimate. For current proceedings not specifically reported below, management does not anticipate that the liabilities, if any, arising from such proceedings would have a material effect on the financial position, liquidity or results of operations of the Companies. Environmental Matters The Companies are subject to costs resulting from a number of federal, state and local laws and regulations designed to protect human health and the environment. These laws and regulations affect future planning and existing operations. They can result in increased capital, operating and other costs as a result of compliance, remediation, containment and monitoring obligations. Air The CAA, as amended, is a comprehensive program utilizing a broad range of regulatory tools to protect and preserve the nation's air quality. At a minimum, states are required to establish regulatory programs to address all requirements of the CAA. However, states may choose to develop regulatory programs that are more restrictive. Many of the Companies' facilities are subject to the CAA's permitting and other requirements. In December 2011, the EPA issued MATS for coal- and oil-fired electric utility steam generating units. The rule establishes strict emission limits for mercury, particulate matter as a surrogate for toxic metals and hydrogen chloride as a surrogate for acid gases. The rule includes a limited use provision for oil-fired units with annual capacity factors under 8% that provides an exemption from emission limits, and allows compliance with operational work practice standards. Compliance was required by April 16, 2015, with certain limited exceptions. However, in June 2014, the VDEQ granted a one -year MATS compliance extension for two coal-fired units at Yorktown to defer planned retirements and allow for continued operation of the units to address reliability concerns while necessary electric transmission upgrades are being completed. Due to delays in transmission upgrades needed to maintain electric reliability, these coal units will need to continue operating until at least early 2017. Therefore, Virginia Power plans to request from the EPA an additional one year compliance extension under an EPA Administrative Order. In June 2015, the U.S. Supreme Court issued a decision holding that the EPA failed to take cost into account when the agency first decided to regulate the emissions from coal- and oil-fired plants, and remanded the MATS rule back to the D.C. Circuit Court. However, the Supreme Court did not vacate or stay the effective date and implementation of the MATS rule. Therefore, the Supreme Court’s decision does not change Dominion’s plans to close coal units at Yorktown or the need to complete necessary electricity transmission upgrades by 2017. At this time, Dominion intends to proceed as scheduled, pending further action regarding the MATS rule by the D.C. Circuit Court. The EPA established CAIR with the intent to require significant reductions in SO 2 and NOx emissions from electric generating facilities. In July 2008, the U.S. Court of Appeals for the D.C. Circuit issued a ruling vacating CAIR. In December 2008, the Court denied rehearing, but also issued a decision to remand CAIR to the EPA. In July 2011, the EPA issued a replacement rule for CAIR, called CSAPR, that required 28 states to reduce power plant emissions that cross state lines. CSAPR established new SO 2 and NOx emissions cap and trade programs that were completely independent of the current ARP. Specifically, CSAPR required reductions in SO 2 and NOx emissions from fossil fuel-fired electric generating units of 25 MW or more through annual NOx emissions caps, NOx emissions caps during the ozone season (May 1 through September 30) and annual SO 2 emission caps with differing requirements for two groups of affected states. Following numerous petitions by industry participants for review and a successful motion for stay, in October 2014, the U.S. Court of Appeals for the D.C. Circuit ordered that the EPA's motion to lift the stay of CSAPR be granted. Further, the Court granted the EPA's request to shift the CSAPR compliance deadlines by three years, so that Phase 1 emissions budgets (which would have gone into effect in 2012 and 2013) will apply in 2015 and 2016, and Phase 2 emissions budgets will apply in 2017 and beyond. CSAPR replaced CAIR beginning in January 2015. The cost to comply is not expected to be material to the Consolidated Financial Statements. Future outcomes of any additional litigation and/or any action to issue a revised rule could affect the assessment regarding cost of compliance. In May 2012, the EPA issued final designations for the 75 -ppb ozone air quality standard. A number of the Companies' facilities are located in areas impacted by this standard. As part of the standard, states will be required to develop and implement plans to address sources emitting pollutants which contribute to the formation of ozone. In November 2014, the EPA issued a new proposal to revise the ozone standard and expects to finalize the rule in October 2015. The EPA is not expected to complete attainment designations for a new standard until 2017 and states will have until 2020 to develop plans to address the new standard. Until the states have developed implementation plans, the Companies are unable to predict whether or to what extent the new rules will ultimately require additional controls. However, if significant expenditures are required to implement additional controls, it could adversely affect the Companies' results of operations and cash flows. In August 2010, the EPA issued revised National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines. The rule was amended in March 2011 and January 2013. The rule establishes emission standards for control of hazardous air pollutants for engines at smaller facilities, known as area sources. As a result of these regulations, Dominion Gas installed emissions controls on several compressor engines. Dominion Gas has spent approximately $2 million to date and is evaluating further expenditures. Dominion Gas is unable to estimate the additional potential impacts on results of operations, financial condition and/or cash flows related to this matter. In August 2012, the EPA issued the first NSPS impacting the natural gas production and gathering sectors and made revisions to the NSPS for natural gas processing and transmission facilities. These rules establish equipment performance specifications and emissions standards for control of volatile organic compound emissions for natural gas production wells, tanks, pneumatic controllers, and compressors in the upstream sector. Compliance with these rules is required for installations and wells constructed or reconstructed after August 23, 2011. The cost to comply with the NSPS will depend on the number of new wells and new equipment installations subject to the rule; therefore, Dominion Gas is unable to estimate the potential impacts on results of operations, financial condition and/or cash flows related to this matter. Water The CWA, as amended, is a comprehensive program requiring a broad range of regulatory tools including a permit program to authorize and regulate discharges to surface waters with strong enforcement mechanisms. The Companies must comply with applicable aspects of the CWA programs at their operating facilities. In October 2014, the final regulations under Section 316(b) of the CWA that govern existing facilities and new units at existing facilities that employ a cooling water intake structure and that have flow levels exceeding a minimum threshold became effective. The rule establishes a national standard for impingement based on seven compliance options, but forgoes the creation of a single technology standard for entrainment. Instead, the EPA has delegated entrainment technology decisions to state regulators. State regulators are to make case-by-case entrainment technology determinations after an examination of five mandatory facility-specific factors, including a social cost-benefit test, and six optional facility-specific factors. The rule governs all electric generating stations with water withdrawals above two MGD, with a heightened entrainment analysis for those facilities over 125 MGD. Dominion and Virginia Power have 14 and 11 facilities, respectively, that may be subject to the final regulations. Dominion anticipates that it will have to install impingement control technologies at many of these stations that have once-through cooling systems. Dominion and Virginia Power are currently evaluating the need or potential for entrainment controls under the final rule as these decisions will be made on a case-by-case basis after a thorough review of detailed biological, technology, cost and benefit studies. While the impacts of this rule could be material to Dominion's and Virginia Power's results of operations, financial condition and/or cash flows, the existing regulatory framework in Virginia provides rate recovery mechanisms that could substantially mitigate any such impacts for Virginia Power. In September 2010, Millstone's NPDES permit was reissued under the CWA. The conditions of the permit require an evaluation of control technologies that could result in additional expenditures in the future. The report summarizing the results of the evaluation was submitted in August 2012 and is under review by the Connecticut Department of Energy and Environmental Protection. Dominion cannot currently predict the outcome of this review. In October 2010, the permit issuance was appealed to the state court by a private plaintiff. The permit is expected to remain in effect during the appeal. In February 2015, the NPDES permit renewal application was submitted to the Connecticut Department of Energy and Environmental Protection along with a schedule to update the evaluation of control technologies consistent with the new federal 316(b) rule. Dominion is currently unable to make an estimate of the potential financial statement impacts related to this matter. Solid and Hazardous Waste The CERCLA, as amended, provides for immediate response and removal actions coordinated by the EPA in the event of threatened releases of hazardous substances into the environment and authorizes the U.S. government either to clean up sites at which hazardous substances have created actual or potential environmental hazards or to order persons responsible for the situation to do so. Under the CERCLA, as amended, generators and transporters of hazardous substances, as well as past and present owners and operators of contaminated sites, can be jointly, severally and strictly liable for the cost of cleanup. These potentially responsible parties can be ordered to perform a cleanup, be sued for costs associated with an EPA-directed cleanup, voluntarily settle with the U.S. government concerning their liability for cleanup costs, or voluntarily begin a site investigation and site remediation under state oversight. From time to time, Dominion, Virginia Power, or Dominion Gas may be identified as a potentially responsible party to a Superfund site. The EPA (or a state) can either allow such a party to conduct and pay for a remedial investigation, feasibility study and remedial action or conduct the remedial investigation and action itself and then seek reimbursement from the potentially responsible parties. Each party can be held jointly, severally and strictly liable for the cleanup costs. These parties can also bring contribution actions against each other and seek reimbursement from their insurance companies. As a result, Dominion, Virginia Power, or Dominion Gas may be responsible for the costs of remedial investigation and actions under the Superfund law or other laws or regulations regarding the remediation of waste. Except as noted below, the Companies do not believe this will have a material effect on results of operations, financial condition and/or cash flows. In September 2011, the EPA issued a UAO to Virginia Power and 22 other parties, ordering specific remedial action of certain areas at the Ward Transformer Superfund site located in Raleigh, North Carolina. Virginia Power does not believe it is a liable party under CERCLA based on its alleged connection to the site. In November 2011, Virginia Power and a number of other parties notified the EPA that they are declining to undertake the work set forth in the UAO. The EPA may seek to enforce a UAO in court pursuant to its enforcement authority under CERCLA, and may seek recovery of its costs in undertaking removal or remedial action. If the court determines that a respondent failed to comply with the UAO without sufficient cause, the EPA may also seek civil penalties of up to $37,500 per day for the violation and punitive damages of up to three times the costs incurred by the EPA as a result of the party's failure to comply with the UAO. Virginia Power is currently unable to make an estimate of the potential financial statement impacts related to the Ward Transformer matter. Dominion has determined that it is associated with 17 former manufactured gas plant sites, three of which pertain to Virginia Power and 12 of which pertain to Dominion Gas. Studies conducted by other utilities at their former manufactured gas plant sites have indicated that those sites contain coal tar and other potentially harmful materials. None of the former sites with which the Companies are associated is under investigation by any state or federal environmental agency. At one of the former sites, Dominion is conducting a state-approved post-closure groundwater monitoring program and an environmental land use restriction has been recorded. Another site has been accepted into a state-based voluntary remediation program. Virginia Power is currently evaluating the nature and extent of the contamination from this site as well as potential remedial options. Preliminary costs for options under evaluation for the site range from $1 million to $22 million . Due to the uncertainty surrounding the other sites, the Companies are unable to make an estimate of the potential financial statement impacts. See below for discussion on ash pond closure costs. Climate Change Legislation and Regulation In October 2013, the U.S. Supreme Court granted petitions filed by several industry groups, states, and the U.S. Chamber of Commerce seeking review of the D.C. Circuit Court's June 2012 decision upholding the EPA’s regulation of GHG emissions from stationary sources under the CAA's permitting programs. In June 2014, the U.S. Supreme Court ruled that the EPA lacked the authority under the CAA to require PSD or Title V permits for stationary sources based solely on GHG emissions. However, the Court upheld the EPA’s ability to require BACT for GHG for sources that are otherwise subject to PSD or Title V permitting for conventional pollutants. In July 2014, the EPA issued a memorandum specifying that it will no longer apply or enforce federal regulations or EPA-approved PSD state implementation plan provisions that require new and modified stationary sources to obtain a PSD permit when GHGs are the only pollutant that would be emitted at levels that exceed the permitting thresholds. In addition, the EPA stated that it will continue to use the existing thresholds to apply to sources that are otherwise subject to PSD for conventional pollutants until it completes a new rulemaking either justifying and upholding those thresholds or setting new ones. Some states have issued interim guidance that follows the EPA guidance. Due to uncertainty regarding what additional actions states may take to amend their existing regulations and what action the EPA ultimately takes to address the court ruling under a new rulemaking, the Companies cannot predict the impact to their financial statements at this time. In July 2011, the EPA signed a final rule deferring the need for PSD and Title V permitting for CO 2 emissions for biomass projects. This rule temporarily deferred for a period of up to three years the consideration of CO 2 emissions from biomass projects when determining whether a stationary source meets the PSD and Title V applicability thresholds, including those for the application of BACT. The deferral policy expired in July 2014. In July 2013, the U.S. Court of Appeals for the D.C. Circuit vacated this rule; however, a mandate making this decision effective has not been issued. Virginia Power converted three coal-fired generating stations, Altavista, Hopewell and Southampton, to biomass during the CO 2 deferral period. It is unclear how the court's decision or the EPA's final policy regarding the treatment of specific feedstock will affect biomass sources that were permitted during the deferral period; however, the expenditures to comply with any new requirements could be material to Dominion's and Virginia Power's financial statements. Other Legal Matters The Companies are defendants in a number of lawsuits and claims involving unrelated incidents of property damage and personal injury. Due to the uncertainty surrounding these matters, the Companies are unable to make an estimate of the potential financial statement impacts; however, they could have a material impact on results of operations, financial condition and/or cash flows. Appalachian Gateway Following the completion of the Appalachian Gateway Project in 2012, DTI received multiple change order requests and other claims for additional payments from a pipeline contractor for the project. In July 2013, DTI filed a complaint in U.S. District Court, Eastern District of Virginia for breach of contract as well as accounting and declaratory relief. The contractor filed a motion to dismiss, or in the alternative, a motion to transfer venue to Pennsylvania and/or West Virginia, where the pipelines were constructed. DTI filed an opposition to the contractor’s motion in August 2013. In November 2013, the court granted the contractor’s motion on the basis that DTI must first comply with the dispute resolution process. Pursuant to the ruling, DTI intends to mediate the matter. This case is pending. DTI has accrued a liability of approximately $6 million for this matter. Dominion Gas cannot currently estimate additional financial statement impacts, but there could be a material impact to its financial condition and/or cash flows. Ash Pond Closure Costs In September 2014, Virginia Power received a notice from the SELC on behalf of the Potomac Riverkeeper and Sierra Club alleging CWA violations at Possum Point. The notice alleges unpermitted discharges to surface water and groundwater from Possum Point's historical and active ash storage facilities. A similar notice from the SELC on behalf of the Sierra Club was subsequently received related to Chesapeake. In December 2014, Virginia Power offered to close all of its coal ash ponds and landfills at Possum Point, Chesapeake and Bremo as settlement of the potential litigation. While the issue is open to potential further negotiations, the SELC declined the offer as presented in January 2015 and, in March 2015, filed a lawsuit related to its claims of the alleged CWA violations at Chesapeake. Virginia Power filed a motion to dismiss in April 2015. A ruling on the motion is pending. As a result of the settlement offer, Virginia Power recognized a charge of $121 million in other operations and maintenance expense in its Consolidated Statements of Income in the Companies' Annual Report on Form 10-K for the year ended December 31, 2014. In April 2015, the EPA's final rule regulating the management of CCRs stored in impoundments (ash ponds) and landfills was published in the Federal Register. The final rule regulates CCR landfills, existing ash ponds that still receive and manage CCRs, and inactive ash ponds that do not receive, but still store CCRs. Virginia Power currently operates inactive ash ponds, existing ash ponds, and CCR landfills subject to the final rule at eight different facilities. The enactment of the final rule in April 2015 created a legal obligation for Virginia Power to retrofit or close all of its inactive and existing ash ponds over a certain period of time, as well as perform required monitoring, corrective action, and post-closure care activities as necessary. In the second quarter of 2015, Virginia Power recorded a $325 million ARO related to future ash pond and landfill closure costs. Recognition of the ARO also resulted in a $45 million incremental charge recorded in other operations and maintenance expense in its Consolidated Statement of Income, a $159 million increase in property, plant, and equipment associated with asset retirement costs, and a $121 million reduction in other noncurrent liabilities related to reversal of the contingent liability described above since the ARO obligation created by the final CCR rule represents similar activities. The actual asset retirement costs related to the CCR rule may vary substantially from the estimates used to record the increased obligation in the second quarter, due to uncertainty about compliance strategies that will be used based on final requirements to be imposed by the various state regulators. Nuclear Matters In March 2011, a magnitude 9.0 earthquake and subsequent tsunami caused significant damage at the Fukushima Daiichi nuclear power station in northeast Japan. These events have resulted in significant nuclear safety reviews required by the NRC and industry groups such as INPO. Like other U.S. nuclear operators, Dominion has been gathering supporting data and participating in industry initiatives focused on the ability to respond to and mitigate the consequences of design-basis and beyond-design-basis events at its stations. In July 2011, an NRC task force provided initial recommendations based on its review of the Fukushima Daiichi accident and in October 2011, the NRC staff prioritized these recommendations into Tiers 1, 2 and 3, with the Tier 1 recommendations consisting of actions which the staff determined should be started without unnecessary delay. In December 2011, the NRC Commissioners approved the agency staff's prioritization and recommendations, and that same month an appropriations act directed the NRC to require reevaluation of external hazards (not limited to seismic and flooding hazards) as soon as possible. Based on the prioritized recommendations, in March 2012, the NRC issued orders and information requests requiring specific reviews and actions to all operating reactors, construction permit holders and combined license holders based on the lessons learned from the Fukushima Daiichi event. The orders applicable to Dominion require implementation of safety enhancements related to mitigation strategies to respond to extreme natural events resulting in the loss of power at plants, and enhancing spent fuel pool instrumentation. The orders require prompt implementation of the safety enhancements and completion of implementation within two refueling outages or by December 31, 2016, whichever comes first. Implementation of these enhancements is currently in progress. The information requests issued by the NRC request each reactor to reevaluate the seismic and flooding hazards at their site using present-day methods and information, conduct walkdowns of their facilities to ensure protection against the hazards in their current design basis, and to reevaluate their emergency communications systems and staffing levels. Dominion and Virginia Power do not currently expect that compliance with the NRC's March 2012 orders and information requests will materially impact their financial position, results of operations or cash flows during the approximately four -year implementation period. The NRC staff is evaluating the implementation of the longer-term Tier 2 and Tier 3 recommendations. Dominion and Virginia Power are currently unable to estimate the potential financial impacts related to compliance with Tier 2 and Tier 3 recommendations. Guarantees, Surety Bonds and Letters of Credit Dominion At June 30, 2015, Dominion had issued $74 million of guarantees, primarily to support equity method investees. No significant amounts related to these guarantees have been recorded. As of June 30, 2015, Dominion’s exposure under these guarantees was $39 million , primarily related to certain reserve requirements associated with non-recourse financing. Dominion also enters into guarantee arrangements on behalf of its consolidated subsidiaries, primarily to facilitate their commercial transactions with third parties. To the extent that a liability subject to a guarantee has been incurred by one of Dominion's consolidated subsidiaries, that liability is included in the Consolidated Financial Statements. Dominion is not required to recognize liabilities for guarantees issued on behalf of its subsidiaries unless it becomes probable that it will have to perform under the guarantees. Terms of the guarantees typically end once obligations have been paid. Dominion currently believes it is unlikely that it would be required to perform or otherwise incur any losses associated with guarantees of its subsidiaries' obligations. At June 30, 2015, Dominion had issued the following subsidiary guarantees: Stated Limit Value (1) (millions) Subsidiary debt (2) $ 27 $ 27 Commodity transactions (3) 2,662 1,126 Nuclear obligations (4) 197 74 Cove Point (5) 1,910 — Solar (6) 1,192 523 Other (7) 536 44 Total $ 6,524 $ 1,794 (1) Represents the estimated portion of the guarantee's stated limit that is utilized as of June 30, 2015 based upon prevailing economic conditions and fact patterns specific to each guarantee arrangement. For those guarantees related to obligations that are recorded as liabilities by Dominion's subsidiaries, the value includes the recorded amount. (2) Guarantee of debt of a DEI subsidiary. In the event of default by the subsidiary, Dominion would be obligated to repay such amounts. (3) Guarantees related to commodity commitments of certain subsidiaries, including subsidiaries of Virginia Power, Dominion Gas and DEI. These guarantees were provided to counterparties in order to facilitate physical and financial transactions in gas, oil, electricity, pipeline capacity, transportation and related commodities and services. If any of these subsidiaries fail to perform or pay under the contracts and the counterparties seek performance or payment, Dominion would be obligated to satisfy such obligation. Dominion and its subsidiaries receive similar guarantees as collateral for credit extended to others. The value provided includes certain guarantees that do not have stated limits. (4) Guarantees related to certain DEI subsidiaries' potential retrospective premiums that could be assessed if there is a nuclear incident under Dominion's nuclear insurance programs and guarantees for a DEI subsidiary's and Virginia Power's commitment to buy nuclear fuel. Excludes Dominion's agreement to provide up to $150 million and $60 million to two DEI subsidiaries to pay the operating expenses of Millstone (in the event of a prolonged outage) and Kewaunee, respectively, as part of satisfying certain NRC requirements concerned with ensuring adequate funding for the operations of nuclear power stations. The agreement for Kewaunee also provides for funds through the completion of decommissioning. (5) Guarantees related to Cove Point, in support of terminal services, transportation and construction. Two of the guarantees have no stated limit, one guarantee has a $150 million limit, and one guarantee has a $1.75 billion aggregate limit with an annual draw limit of $175 million . (6) Includes guarantees to facilitate the development of solar projects including guarantees to support the issuance of full notice to proceed under EPC agreements. Includes certain guarantees that do not have stated limits. Also includes guarantees entered into by DEI on behalf of certain subsidiaries to facilitate the acquisition and development of solar projects. (7) Guarantees related to other miscellaneous contractual obligations such as leases, environmental obligations and construction projects. Also includes guarantees related to certain DEI subsidiaries' obligations for equity capital contributions and energy generation associated with Fowler Ridge and NedPower. As of June 30, 2015, Dominion's maximum remaining cumulative exposure under these equity funding agreements is $63 million through 2019 and its maximum annual future contributions could range from approximately $4 million to $19 million . The value provided includes certain guarantees that do not have stated limits. Additionally, at June 30, 2015, Dominion had purchased $132 million of surety bonds, including $66 million at Virginia Power and $30 million at Dominion Gas, and authorized the issuance of letters of credit by financial institutions of $56 million to facilitate commercial transactions by its subsidiaries with third parties. Under the terms of surety bonds, the Companies are obligated to indemnify the respective surety bond company for any amounts paid.

Risks and Uncertainties [Abstract]
Credit Risk	Credit Risk The Companies' accounting policies for credit risk are discussed in Note 23 to the Consolidated Financial Statements in the Companies' Annual Report on Form 10-K for the year ended December 31, 2014. At June 30, 2015, Dominion's credit exposure related to energy marketing and price risk management activities totaled $276 million . Of this amount, investment grade counterparties, including those internally rated, represented 80% . No single counterparty, whether investment grade or non-investment grade, exceeded $35 million of exposure. Credit-Related Contingent Provisions The majority of Dominion's derivative instruments contain credit-related contingent provisions. These provisions require Dominion to provide collateral upon the occurrence of specific events, primarily a credit rating downgrade. If the credit-related contingent features underlying these instruments that are in a liability position and not fully collateralized with cash were fully triggered as of June 30, 2015 and December 31, 2014, Dominion would have been required to post an additional $18 million and $20 million , respectively, of collateral to its counterparties. The collateral that would be required to be posted includes the impacts of any offsetting asset positions and any amounts already posted for derivatives, non-derivative contracts and derivatives elected under the normal purchases and normal sales exception, per contractual terms. Dominion had posted approximately $71 million and $1 million in collateral at June 30, 2015 and December 31, 2014, respectively, related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. The collateral posted includes any amounts paid related to non-derivative contracts and derivatives elected under the normal purchases and normal sales exception, per contractual terms. The aggregate fair value of all derivative instruments with credit-related contingent provisions that are in a liability position and not fully collateralized with cash as of June 30, 2015 and December 31, 2014 was $47 million and $49 million , respectively, which does not include the impact of any offsetting asset positions. Credit-related contingent provisions for Virginia Power and Dominion Gas were not material as of June 30, 2015 and December 31, 2014. See Note 9 for further information about derivative instruments. Dominion Gas In the second quarter of 2015, DTI provided service to 242 customers with approximately 95% of its storage and transportation revenue being provided through firm services. The ten largest customers provided approximately 42% of total storage and transportation revenue and the thirty largest provided approximately 73% of total storage and transportation revenue. Approximately 99% of the transmission capacity under contract on DTI’s pipeline is subscribed with long-term contracts ( two years or greater). The remaining 1% is contracted on a year-to-year basis. Less than 1% of firm transportation capacity is currently unsubscribed. All storage services are subscribed under long-term contracts. East Ohio distributes natural gas to residential, commercial and industrial customers in Ohio using rates approved by the Ohio Commission. Approximately 99% of East Ohio revenues are derived from its jurisdictional gas services. East Ohio’s bad debt risk is mitigated by the regulatory framework established by the Ohio Commission.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Virginia Power and Dominion Gas engage in related party transactions primarily with other Dominion subsidiaries (affiliates). Virginia Power's and Dominion Gas' receivable and payable balances with affiliates are settled based on contractual terms or on a monthly basis, depending on the nature of the underlying transactions. Virginia Power and Dominion Gas are included in Dominion's consolidated federal income tax return. A discussion of significant related party transactions follows. Virginia Power Transactions with Affiliates Virginia Power transacts with affiliates for certain quantities of natural gas and other commodities in the ordinary course of business. Virginia Power also enters into certain commodity derivative contracts with affiliates. Virginia Power uses these contracts, which are principally comprised of commodity swaps, to manage commodity price risks associated with purchases of natural gas. See Notes 7 and 9 for more information. Virginia Power participates in certain Dominion benefit plans described in Note 19. In Virginia Power's Consolidated Balance Sheets at June 30, 2015 and December 31, 2014, amounts due to Dominion associated with these benefit plans included in other deferred credits and other liabilities were $268 million and $219 million , respectively, and amounts due from Dominion at June 30, 2015 included in other deferred charges and other assets were $56 million . DRS and other affiliates provide accounting, legal, finance and certain administrative and technical services to Virginia Power. In addition, Virginia Power provides certain services to affiliates, including charges for facilities and equipment usage. Presented below are Virginia Power's significant transactions with DRS and other affiliates: Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 (millions) Commodity purchases from affiliates $ 94 $ 113 $ 346 $ 315 Services provided by affiliates (1) 107 106 217 214 Services provided to affiliates 5 6 10 11 (1) Includes capitalized expenditures.

[1]	Dominion’s Consolidated Balance Sheet at December 31, 2014 has been derived from the audited Consolidated Financial Statements at that date.
[2]	At June 30, 2015 and December 31, 2014, includes the valuation of certain fair value hedges associated with fixed rate debt of approximately $8 million and $19 million, respectively.
[3]	Carrying amount includes amounts which represent the unamortized discount and/or premium.
[4]	Fair value is estimated using market prices, where available, and interest rates currently available for issuance of debt with similar terms and remaining maturities. All fair value measurements are classified as Level 2. The carrying amount of debt issues with short-term maturities and variable rates refinanced at current market rates is a reasonable estimate of their fair value.
