Significant Accounting Policies | Note 2. 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, 2021. In the Companies’ opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position at September 30, 2022, their results of operations and changes in equity for the three and nine months ended September 30, 2022 and 2021 and their cash flows for the nine months ended September 30, 2022 and 2021. 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. Clearway’s ownership interest in Four Brothers and Three Cedars (through December 2021) and Terra Nova Renewable Partners’ 33% interest in certain Dominion Energy nonregulated solar projects (through December 2021) are reflected as noncontrolling interest in Dominion Energy’s Consolidated Financial Statements. See Note 10 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021 for additional information. 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’ 2021 Consolidated Financial Statements and Notes have been reclassified to conform to the 2022 presentation for comparative purposes; however, such reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows. Amounts disclosed for Dominion Energy are inclusive of Virginia Power, where applicable. There have been no significant changes from Note 2 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021, with the exception of the items described below. Cash, Restricted Cash and Equivalents Restricted Cash and Equivalents The following table provides a reconciliation of the total cash, restricted cash and equivalents reported within the Companies’ Consolidated Balance Sheets to the corresponding amounts reported within the Companies’ Consolidated Statements of Cash Flows for the nine months ended September 30, 2022 and 2021: Cash, Restricted Cash and Equivalents at End of Period Cash, Restricted Cash and Equivalents at Beginning of Period September 30, 2022 September 30, 2021 December 31, 2021 December 31, 2020 (millions) Dominion Energy Cash and cash equivalents (1) $ 163 $ 195 $ 283 $ 179 Restricted cash and equivalents (2)(3) 177 72 125 68 Cash, restricted cash and equivalents shown in the Consolidated Statements of Cash Flows $ 340 $ 267 $ 408 $ 247 Virginia Power Cash and cash equivalents $ 18 $ 38 $ 26 $ 35 Restricted cash and equivalents (3) 2 1 — — Cash, restricted cash and equivalents shown in the Consolidated Statements of Cash Flows $ 20 $ 39 $ 26 $ 35 (1) At September 30, 2021 and December 31, 2020, Dominion Energy had $15 million and $7 million of cash and cash equivalents included in current assets held for sale, respectively.

Supplemental Cash Flow Information The following table provides supplemental disclosure of cash flow information related to Dominion Energy: Nine Months Ended September 30, 2022 2021 (millions) Significant noncash investing and financing activities: (1) Accrued capital expenditures $ 745 $ 374 Leases (2) 129 75 (1) See Note 10 for noncash investing activities related to the acquisition of a noncontrolling interest in Dominion Privatization and Notes 16 and 17 for noncash financing activities related to the remarketing of Series A Preferred Stock and the issuance of common stock and transfer of property associated with the settlement of litigation. (2) Includes $29 million and $34 million of financing leases at September 30, 2022 and 2021, respectively, and $100 million and $41 million of operating leases at September 30, 2022 and 2021, respectively. The following table provides supplemental disclosure of cash flow information related to Virginia Power: Nine Months Ended September 30, 2022 2021 (millions) Significant noncash investing and financing activities: Accrued capital expenditures $ 454 $ 238 Leases (1) 113 59 (1) Includes $20 million and $24 million of financing leases at September 30, 2022 and 2021, respectively, and $93 million and $35 million of operating leases at September 30, 2022 and 2021, respectively Property, Plant and Equipment In the first quarter of 2022, Virginia Power revised the depreciation rates for its assets to reflect the results of a new depreciation study. The change resulted in a decrease in depreciation expense in Virginia Power’s Consolidated Statements of Income of $15 million ($11 million after-tax) and $45 million ($33 million after-tax) for the three and nine months ended September 30, 2022, respectively, and an increase in Dominion Energy’s EPS of $0.01 and $0.04 for the three and nine months ended September 30, 2022, respectively. The revision is expected to decrease Virginia Power’s annual depreciation expense by approximately $60 million ($45 million after-tax) and increase Dominion Energy’s EPS by approximately $0.05. For the three and nine months ended September 30, 2022, Virginia Power recorded charges of $18 million ($14 million after-tax) and $60 million ($45 million after-tax), respectively, associated with dismantling certain coal- and oil-fired generating units retired before the end of their useful lives, recorded in impairment of assets and other charges (benefits) in its Consolidated Statements of Income. Asset Retirement Obligations In the second quarter of 2021, Dominion Energy revised its estimated cash flow projections associated with the recovery of spent nuclear fuel costs for its AROs associated with the decommissioning of Kewaunee. As a result, Dominion Energy recorded a charge of $44 million ($35 million after-tax) within other operations and maintenance expense in its Consolidated Statements of Income. |

Acquisitions and Dispositions | Note 3. Acquisitions and Dispositions Disposition of Gas Transmission & Storage Operations In December 2021, Dominion Energy completed the sale of the Q-Pipe Group to Southwest Gas, as discussed in Note 3 to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. In the first quarter of 2022, Dominion Energy recognized a gain of $27 million ($20 million after-tax) in discontinued operations in its Consolidated Statements of Income associated with finalization of working capital adjustments. In connection with the closing of the sale of the Q-Pipe Group, Dominion Energy and Southwest Gas entered into a transition services agreement under which Dominion Energy will continue to provide specified administrative services to support the operations of the disposed businesses for up to 12 months after closing, subject to extension. Dominion Energy recorded $2 million and $5 million associated with the transition services agreement in operating revenue in the Consolidated Statements of Income for the three and nine months ended September 30, 2022, respectively. The following table represents selected information regarding the results of operations, which were reported within discontinued operations in Dominion Energy’s Consolidated Statements of Income: Three Months Ended September 30, 2021 Nine Months Ended September 30, 2021 Q-Pipe Group Q-Pipe Group (millions) Operating revenue $ 62 $ 188 Operating expense 24 52 Other income (1) 26 27 Interest and related charges 7 17 Income before income taxes ( 2 ) 57 146 Income tax expense 12 29 Net income attributable to Dominion Energy $ 45 $ 117 (1) Includes a $25 million benefit associated with the termination of the Q-Pipe Transaction in the third quarter of 2021. (2) Excludes $18 million income tax benefit recorded in the third quarter of 2021 associated with the GT&S Transaction. Capital expenditures and significant noncash items relating to the Q-Pipe Group included the following: Nine Months Ended September 30, 2021 (millions) Capital expenditures $ 26 Significant noncash items: Accrued capital expenditures 2 Sale of Hope In February 2022, Dominion Energy entered into an agreement to sell 100% of the equity interests in Hope to Ullico for $690 million of cash consideration, subject to customary closing adjustments, which closed in August 2022 after all customary closing and regulatory conditions were satisfied, including clearance under the Hart-Scott-Rodino Act and approval from the West Virginia Commission. The sale is treated as a stock sale for tax purposes. Upon closing, Dominion Energy recognized a pre-tax gain of $8 million, subject to customary closing adjustments, (net of $110 million write-off of goodwill which was not deductible for tax purposes) in losses (gains) on sales of assets in its Consolidated Statements of Income. The transaction resulted in an after-tax loss of $89 million. Upon meeting the classification as held for sale in the first quarter of 2022 and through the second quarter of 2022, Dominion Energy had recorded charges of $90 million in deferred income tax expense in its Consolidated Statements of Income to reflect the recognition of deferred taxes on the outside basis of Hope’s stock. This deferred income tax expense reversed upon closing of the sale and became a component of current income tax expense on the sale disclosed above. See Note 5 for additional information. In addition, a curtailment was recorded related to other postretirement benefit plans as discussed in Note 20. All activity related to Hope prior, or not related, to closing, is included in Gas Distribution. Sale of Kewaunee In May 2021, Dominion Energy entered into an agreement to sell 100% of the equity interests in Dominion Energy Kewaunee, Inc. to EnergySolutions, including the transfer of all decommissioning obligations associated with Kewaunee, which ceased operations in 2013. The sale closed in June 2022 following approval from the Wisconsin Commission in May 2022 and NRC approval of a requested license transfer in March 2022. The sale is treated as an asset sale for tax purposes and Dominion Energy retained the assets and obligations of the pension and other postretirement employee benefit plans. EnergySolutions is subject to the Wisconsin regulatory conditions agreed to by Dominion Energy upon its acquisition of Kewaunee, including the return of any excess decommissioning funds to WPSC and WP&L customers following completion of all decommissioning activities. In the second quarter of 2022, Dominion Energy recorded a loss of $649 million ($513 million after-tax), recorded in losses (gains) on sales of assets in its Consolidated Statements of Income, primarily related to the difference between the nuclear decommissioning trust and AROs. Prior to its receipt, there had been uncertainty as to the timing of or ability to obtain approval from the Wisconsin Commission. Prior to closing, Dominion Energy withdrew $80 million from the nuclear decommissioning trust to recover certain spent nuclear fuel and other permitted costs. All activity related to Kewaunee prior to closing is included in Contracted Assets. |

These revenues relate to contracts containing fixed prices where Dominion Energy will earn the associated revenue over time as it stands ready to perform services provided. This disclosure does not include revenue related to performance obligations that are part of a contract with original durations of one year or less. In addition, this disclosure does not include expected consideration related to performance obligations for which Dominion Energy elects to recognize revenue in the amount it has a right to invoice. Revenue expected to be recognized on multi-year contracts in place at September 30, 2022 2022 2023 2024 2025 2026 Thereafter Total (millions) Dominion Energy $ 18 $ 68 $ 61 $ 54 $ 48 $ 449 $ 698 At September 30, 2022 and December 31, 2021, Dominion Energy’s contract liability balances were $159 million and $124 million, respectively, and are recorded in other current liabilities and other deferred credits and other liabilities in the Consolidated Balance Sheets. At September 30, 2022 and December 31, 2021, Virginia Power’s contract liability balances were $43 million and $33 million, respectively, and are recorded in other current liabilities and other deferred credits and other liabilities in its Consolidated Balance Sheets. The Companies recognize revenue as they fulfill their obligations to provide service to their customers. During the nine months ended September 30, 2022 and 2021, Dominion Energy recognized revenue of $120 million and $124 million, respectively, from the beginning contract liability balances. During the nine months ended September 30, 2022 and 2021, Virginia Power recognized $33 million and $36 million, respectively, from the beginning contract liability balances. |

Income Taxes | Note 5. Income Taxes For continuing operations, including noncontrolling interests, the statutory U.S. federal income tax rate reconciles to the Companies’ effective income tax rate as follows: Dominion Energy Virginia Power Nine Months Ended September 30, 2022 2021 2022 2021 U.S. statutory rate 21.0 % 21.0 % 21.0 % 21.0 % Increases (reductions) resulting from: Recognition of taxes - sale of subsidiary stock 7.3 — — — State taxes, net of federal benefit 4.7 2.0 4.4 4.5 Investment tax credits (6.4 ) (5.6 ) (8.9 ) (5.8 ) Production tax credits (0.7 ) (0.5 ) (1.0 ) (0.6 ) Reversal of excess deferred income taxes (6.1 ) (3.8 ) (3.7 ) (2.2 ) State legislative change — (1.0 ) — (1.0 ) Changes in state deferred taxes associated with assets held for sale 0.4 (0.5 ) — — AFUDC - equity (0.6 ) (0.5 ) (0.8 ) (0.5 ) Absence of tax on noncontrolling interest — (0.2 ) — — Other, net (0.4 ) (1.1 ) 0.5 — Effective tax rate 19.2 % 9.8 % 11.5 % 15.4 % As described in Note 3, Dominion Energy sold 100% of the equity interests in Hope in a stock sale for income tax purposes. Dominion Energy’s 2022 effective tax rate reflects the current income tax expense on the sale of Hope’s stock. As of September 30, 2022, there have been no material changes in the Companies’ unrecognized tax benefits. It is reasonably possible that recent case law and interactions with the taxing authority could result in a decrease in unrecognized tax benefits by up to $26 million during the next twelve months. If such changes were to occur, other than revisions of the accrual for interest on tax underpayments and overpayments, earnings could increase by up to $26 million for Dominion Energy. See Note 5 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021, for a discussion of these unrecognized tax benefits. The Companies’ 2021 effective tax rates reflect the benefit of a state legislative change enacted in April 2021 for tax years beginning January 1, 2022. Dominion Energy’s effective tax rate reflects a $21 million deferred tax benefit, inclusive of a $16 million deferred tax benefit at Virginia Power. Discontinued operations Income tax expense reflected in discontinued operations is $4 million and $5 million for the nine months ended September 30, 2022 and 2021, respectively. 2021 income taxes include a $15 million benefit related to finalizing income tax returns on the GT&S Transaction. |

In accordance with revised accounting standards effective January 2022, a fair value adjustment, if dilutive, of the Series A Preferred Stock was no longer included in applying the if converted method to the 2019 Equity Units. In addition, diluted net income was no longer reduced by the Series A Preferred Stock dividends. No fair value adjustment was necessary for the three and nine months ended September 30, 2021. (2) Dilutive securities for the three and nine months ended September 30, 2022 consist primarily of the 2019 Equity Units through their settlement in June 2022 (applying the if converted method as updated effective January 2022), stock potentially to be issued to satisfy the obligation under a settlement agreement with the SCDOR (applying the if converted method) as well as forward sales agreements entered into in November 2021 (applying the treasury stock method). See Notes 16 and 17 for additional information The 2019 Equity Units, prior to settlement in June 2022, and the Q-Pipe Transaction deposit, prior to being settled in cash in July 2021, were potentially dilutive instruments. See Note 16 to the Consolidated Financial Statements in this report and Note 3 and Note 19 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021 for additional information. For the three and nine months ended September 30, 2021, the forward stock purchase contracts included within the 2019 Equity Units are excluded from the calculation of diluted EPS from continuing operations as the dilutive stock price threshold was not met, the Series A Preferred Stock included within the 2019 Equity Units is excluded from the calculation of diluted EPS from continuing operations based upon the expectation that the conversion would settle in cash rather than through the issuance of Dominion Energy common stock and a fair value adjustment related to the Series A Preferred Stock included within the 2019 Equity Units is excluded from the calculation of diluted EPS from continuing operations, as such fair value adjustment was not dilutive during the period. The impact of settling the deposit associated with the Q-Pipe Transaction in shares is excluded from the calculation of diluted EPS from continuing operations for the three and nine months ended September 30, 2021 based upon the expectation Dominion Energy would settle in cash, which occurred in July 2021, rather than through the issuance of Dominion Energy common stock. |

Fair Value Measurements | Note 8. 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, 2021. See Note 9 in this report for additional information about the Companies’ derivatives and hedge accounting activities. The Companies enter into certain physical and financial forwards, futures and options, 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 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, certain forward market prices and implied price volatilities are considered unobservable. The following table presents Dominion Energy’s quantitative information about Level 3 fair value measurements at September 30, 2022. The range and weighted average are presented in dollars for market price inputs and percentages for price volatility. Fair Value (millions) Valuation Techniques Unobservable Input Range Weighted Average (1) Assets Physical and financial forwards: Natural gas (2) $ 1 Discounted cash flow Market price (per Dth) (3) (2) - 6 (1) FTRs 263 Discounted cash flow Market price (per MWh) (3) 1-19 5 Electricity 211 Discounted cash flow Market price (per MWh) (3) 28-199 51 Physical options: Natural gas (2) 24 Option model Market price (per Dth) (3) 4-17 10 Price volatility (4) 13%-70% 51% Total assets $ 499 Liabilities Physical and financial forwards: Natural gas (2) $ 12 Discounted cash flow Market price (per Dth) (3) (2)-8 1 FTRs 5 Discounted cash flow Market price (per MWh) (3) 1-10 4 Total liabilities $ 17 (1) Averages weighted by volume.

The valuation is considered a Level 2 fair value measurement given that it is based on bids received. See Note 10 for information regarding nonrecurring fair value measurements associated with Dominion Energy’s noncontrolling ownership interest in Dominion Privatization.

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, restricted cash and equivalents, customer and other receivables, affiliated receivables, short-term debt, mandatorily redeemable preferred stock, 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: September 30, 2022 December 31, 2021 Carrying Amount Estimated Fair Value (1) Carrying Amount Estimated Fair Value (1) (millions) Dominion Energy Long-term debt (2) $ 38,487 $ 34,700 $ 35,996 $ 40,947 Supplemental credit facility borrowings 450 450 — — Junior subordinated notes (3) 1,387 1,338 1,386 1,470 Virginia Power Long-term debt (3) $ 15,618 $ 13,840 $ 13,753 $ 16,021 (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 issuances with short-term maturities and variable rates refinanced at current market rates is a reasonable estimate of their fair value. (2) Carrying amount includes current portions included in securities due within one year and amounts which represent the unamortized debt issuance costs and discount or premium. At December 31, 2021 the carrying amount includes the valuation of certain fair value hedges associated with fixed rate debt of $2 million. There were no fair value hedges associated with fixed rate debt at September 30, 2022. ( 3 ) Carrying amount includes current portions included in securities due within one year and amounts which represent the unamortized debt issuance costs, discount or premium. |

Derivatives and Hedge Accounting Activities | Note 9. Derivatives and Hedge Accounting Activities The Companies’ accounting policies, 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, 2021. See Note 8 in this report for additional information about fair value measurements and associated valuation methods for derivatives. Derivative assets and liabilities are presented gross on the Companies’ Consolidated Balance Sheets. The Companies’ 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. Over-the-counter contracts are bilateral contracts that are transacted directly with a third party. 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. In February 2022, Dominion Energy entered into contracts representing offsetting positions to certain existing exchange contracts with collateral requirements as well as new over-the-counter transactions that are not subject to collateral requirements. These contracts resulted in positions which limit the risk of increased cash collateral requirements. Certain accounts receivable and accounts payable recognized on the Companies’ Consolidated Balance Sheets, letters of credit and other forms of securities, as well as certain other long-term debt, 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. See Note 18 for additional information regarding credit-related contingent features for the Companies’ derivative instruments. Dominion Energy Balance Sheet Presentation The tables below present Dominion Energy’s derivative asset and liability balances by type of financial instrument, if the gross amounts recognized in its Consolidated Balance Sheets were netted with derivative instruments and cash collateral received or paid: September 30, 2022 December 31, 2021 Gross Amounts Not Offset in the Consolidated Balance Sheet Gross Amounts Not Offset in the Consolidated Balance Sheet Gross Assets Presented in the Consolidated Balance Sheet (1) Financial Instruments Cash Collateral Received Net Amounts Gross Assets Presented in the Consolidated Balance Sheet (1) Financial Instruments Cash Collateral Received Net Amounts (millions) Commodity contracts: Over-the-counter $ 367 $ 11 $ — $ 356 $ 153 $ 13 $ — $ 140 Exchange 292 287 — 5 9 7 — 2 Interest rate contracts: Over-the-counter 1,593 410 — 1,183 323 49 — 274 Foreign currency exchange rate contracts: Over-the-counter 6 6 — — 8 — — 8 Total derivatives, subject to a master netting or similar arrangement $ 2,258 $ 714 $ — $ 1,544 $ 493 $ 69 $ — $ 424 (1) Excludes $211 September 30, 2022 December 31, 2021 Gross Amounts Not Offset in the Consolidated Balance Sheet Gross Amounts Not Offset in the Consolidated Balance Sheet Gross Liabilities Presented in the Consolidated Balance Sheet (1) Financial Instruments Cash Collateral Paid Net Amounts Gross Liabilities Presented in the Consolidated Balance Sheet (1) Financial Instruments Cash Collateral Paid Net Amounts (millions) Commodity contracts: Over-the-counter $ 660 $ 17 $ 121 $ 522 $ 95 $ 13 $ 54 $ 28 Exchange 849 287 562 — 374 7 367 — Interest rate contracts: Over-the-counter 475 257 3 215 399 49 11 339 Foreign currency exchange rate contracts: Over-the-counter 387 153 — 234 — — — — Total derivatives, subject to a master netting or similar arrangement $ 2,371 $ 714 $ 686 $ 971 $ 868 $ 69 $ 432 $ 367 (1) There were no derivative liabilities that are not subject to master netting or similar arrangements at September 30, 2022 or December 31, 2021.

Fair Value Hedges For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings and presented in the same line item. There were no derivative instruments designated as fair value hedges during the three and nine months ended September 30, 2022 and 2021.

At September 30, 2022 and December 31, 2021, the net difference between the carrying amount of Dominion Energy’s investments and its share of underlying equity in net assets was $227 million and $244 million, respectively. At September 30, 2022, these differences are primarily comprised of $ million of equity method goodwill that is not being amortized and a $ million basis difference from Dominion Energy’s investment in Cove Point, which is being amortized over the useful lives of the underlying assets. At December 31, 2021, these differences are comprised of $27 million of equity method goodwill that is not being amortized, a $221 million basis difference from Dominion Energy’s investment in Cove Point, which is being amortized over the useful lives of the underlying assets, and a net $(4) million basis difference primarily attributable to an unfunded commitment made to Align RNG. Cove Point Dominion Energy holds a 50% noncontrolling limited partnership interest in Cove Point which is accounted for as an equity method investment, as discussed in Note 9 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. Income before income taxes recorded for 100% of Cove Point was $197 million and $136 million for the three months ended September 30, 2022 and 2021, respectively, and $506 million and $410 million for the nine months ended September 30, 2022 and 2021, respectively. Earnings attributable to Dominion Energy are presented within earnings from equity method investees Dominion Energy recorded distributions from Cove Point of $98 million and $85 million for the three months ended September 30, 2022 and 2021, respectively, and $259 million and $235 million for the nine months ended September 30, 2022 and 2021, respectively. Atlantic Coast Pipeline A description of Dominion Energy’s investment in Atlantic Coast Pipeline, including events that led to the cancellation of the Atlantic Coast Pipeline Project in July 2020, is included in Note 9 to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. At September 30, 2022 and December 31, 2021, Dominion Energy has recorded a liability of $119 million and $113 million, respectively, in other current liabilities in its Consolidated Balance Sheets as a result of its share of equity losses exceeding its investment which reflects Dominion Energy’s obligations on behalf of Atlantic Coast Pipeline related to its AROs. Dominion Energy recorded contributions of $965 million during the nine months ended September 30, 2021 to Atlantic Coast Pipeline. Dominion Energy recorded no contributions during the nine months ended September 30, 2022 to Atlantic Coast Pipeline. Dominion Energy expects to incur additional losses from Atlantic Coast Pipeline as it completes wind-down activities. While Dominion Energy is unable to precisely estimate the amounts to be incurred by Atlantic Coast Pipeline, the portion of such amounts attributable to Dominion Energy is not expected to be material to Dominion Energy’s results of operations, financial position or statement of cash flows. Wrangler In March 2022, Dominion Energy sold its remaining 15% noncontrolling partnership interest in Wrangler to Interstate Gas Supply, Inc. for cash consideration of $85 million. Dominion Energy recognized a gain of $11 million ($8 million after-tax), included in other income (expense), in its Consolidated Statements of Income for the nine months ended September 30, 2022. All activity related to Wrangler is recorded within the Corporate and Other segment. Dominion Privatization In February 2022, Dominion Energy entered into an agreement to form Dominion Privatization, a partnership with Patriot. Dominion Privatization, through its wholly-owned subsidiaries, will maintain and operate electric and gas distribution infrastructure under service concession arrangements with certain U.S. military installations. Under the agreement, Dominion Energy will contribute its existing privatization operations, excluding contracts held by DESC, and Patriot will contribute cash. The initial contribution, consisting of privatization operations in South Carolina, Texas and Pennsylvania, closed in March 2022 for which Dominion Energy received total consideration of $120 million, subject to customary closing adjustments, comprised of $60 million in cash proceeds and a 50% noncontrolling ownership interest in Dominion Privatization with an initial fair value of $60 million, estimated using the market approach. This is considered a Level 2 fair value measurement given that it is based on the agreed-upon sales price. In the first quarter of 2022, Dominion Energy recorded a gain of $23 million ($16 million after-tax), presented in losses (gains) on sales of assets in its Consolidated Statements of Income. Dominion Energy’s 50% noncontrolling ownership interest in Dominion Privatization is accounted for as an equity method investment as Dominion Energy has the ability to exercise significant influence, but not control, over the investee. Dominion Energy expects to contribute its existing privatization operations in Virginia to Dominion Privatization by the end of 2022, contingent on clearance or approval under the Hart-Scott-Rodino Act and other customary closing and regulatory conditions. In April 2022, Dominion Energy filed with the Federal Trade Commission for approval under the Hart-Scott-Rodino Act. In May 2022, the waiting period under the Hart-Scott-Rodino Act expired. The contribution of the service concession arrangements currently held by Virginia Power also requires approval from the Virginia and North Carolina Commissions. In May 2022, Virginia Power filed for such approval with the Virginia and North Carolina Commissions. In July and September 2022, the Virginia Commission and North Carolina Commission, respectively, approved the request to transfer at net book value. Upon closing of the second contribution, Dominion Energy expects to receive cash proceeds totaling $108 million, subject to customary closing adjustments, and to recognize a gain of approximately $130 million ($100 million after-tax). When this future contribution occurs, Dominion Energy expects to maintain a 50% noncontrolling ownership interest in Dominion Privatization. At September 30, 2022, $83 million of contracts and related assets and $4 million of liabilities associated with existing privatization operations in Virginia are classified as held for sale and reflected in current assets held for sale and other current liabilities, respectively, in Dominion Energy’s Consolidated Balance Sheets and in other current assets and other current liabilities, respectively, in Virginia Power’s Consolidated Balance Sheets. All activity related to Dominion Privatization is reflected within the Corporate and Other segment. |

Regulatory Matters | Note 13. 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 regulatory matters that the Companies cannot estimate, 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 that 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. 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, 2021. Virginia Regulation Virginia Fuel Expenses In May 2022, Virginia Power filed its annual fuel factor filing with the Virginia Commission to recover an estimated $2.3 billion in Virginia jurisdictional projected fuel expense for the rate year beginning July 1, 2022 and a projected $1.0 billion under-recovered balance as of June 30, 2022. Virginia Power’s proposed fuel rate represents a fuel revenue increase of $1.8 billion when applied to projected kilowatt-hour sales for that period. Virginia Power also proposed alternatives to recover this under-collected balance over a two- or three-year period. Under these alternatives, Virginia Power’s fuel revenues for the rate year would increase by $1.3 billion or $1.2 billion, respectively. In addition, Virginia Power proposed a change in the timing of fuel cost recovery for certain customers who elect market-based rates that would consider those customers’ portion of the projected under-recovered balance to have been recovered as of June 30, 2022. In July 2022, Virginia Power, the Virginia Commission staff and another party filed a comprehensive settlement agreement with the Virginia Commission for approval. The comprehensive settlement agreement provides for the collection of the requested under-recovered projected fuel expense over a three-year three-year In September 2022, the Virginia Commission approved the comprehensive settlement agreement Renewable Generation Projects In September 2021, Virginia Power filed a petition with the Virginia Commission for CPCNs to construct and operate 13 utility-scale projects totaling approximately 661 MW of solar generation and 70 MW of energy storage as part of its efforts to meet the renewable generation development requirements under the VCEA. The projects, as of September 2021, are expected to cost approximately $1.4 billion in the aggregate, excluding financing costs, and be placed into service between 2022 and 2023. In March 2022, the Virginia Commission approved the petition. In October 2022, Virginia Power filed a petition with the Virginia Commission for CPCNs to construct and operate eight utility-scale projects totaling approximately generation development requirements under the VCEA. The projects , as of October 2022, are expected to cost approximately $ 1.2 billion in the aggregate, excluding financing costs, and be placed into service between 2024 through 2025. This matter is pending. In November 2021, Virginia Power filed an application with the Virginia Commission requesting approval and certification of the Virginia Facilities component of the CVOW Commercial Project. The onshore Virginia Facilities have an estimated cost of approximately $1.1 billion, excluding financing costs, which is included within the overall cost of the CVOW Commercial Project. In addition, Virginia Power requested approval from the Virginia Commission to enter into financial hedges with U.S. financial institutions to mitigate the foreign currency exchange risk associated with certain supplier contracts associated with the CVOW Commercial Project. In August 2022, the Virginia Commission approved the application for certification of the Virginia Facilities component of the CVOW Commercial Project and noted that no further action was required with respect to Virginia Power’s foreign currency risk mitigation plan. Also in August 2022, Virginia Power filed a petition for limited reconsideration relating to the performance standard for operation of the CVOW Commercial Project included in the Virginia Commission’s August order. The Virginia Commission granted reconsideration and suspended in part the August order pending its reconsideration. In October 2022, Virginia Power, Office of the Attorney General of Virginia and other parties filed a settlement agreement with the Virginia Commission for approval. The settlement agreement provides for certain cost sharing mechanisms of total construction costs between $10.3 billion and $13.7 billion, as subject to potential adjustment to the extent construction costs are decreased by the IRA, and includes enhanced performance reporting provisions associated with operation of the CVOW Commercial Project in lieu of a performance guarantee. This matter is pending. Nuclear Life Extension In October 2021, Virginia Power filed a petition with the Virginia Commission requesting a determination that it is reasonable and prudent for Virginia Power to pursue a nuclear life extension program to extend the operating licenses of Surry and North Anna and to carry out projects to upgrade or replace systems and equipment necessary to continue to safely and reliably operate these nuclear power stations. The nuclear life extension program is expected to cost approximately $3.9 billion, excluding financing costs. In July 2022, the Virginia Commission approved the petition. Riders Developments for significant riders associated with various Virginia Power projects are as follows: Rider Name Application Date Approval Date Rate Year Beginning Total Revenue Requirement (millions) Increase (Decrease) Over Previous Year (millions) Rider B June 2022 Pending April 2023 $ 34 $ 18 Rider B June 2022 Pending April 2024 34 — Rider BW October 2021 May 2022 September 2022 145 32 Rider BW October 2021 May 2022 September 2023 120 (25 ) Rider CCR February 2022 October 2022 December 2022 231 15 Rider CE ( 1) September 2021 March 2022 May 2022 71 61 Rider CE ( 2) October 2022 Pending May 2023 89 18 Rider E January 2022 September 2022 November 2022 101 34 Rider GT August 2021 May 2022 June 2022 56 N/A Rider GT August 2022 Pending June 2023 16 (40 ) Rider OSW November 2021 August 2022 (3) September 2022 79 N/A Rider OSW November 2022 Pending September 2023 271 192 Rider R June 2021 March 2022 April 2022 59 1 Rider R June 2021 March 2022 April 2023 55 (4 ) Rider RGGI ( 4) December 2021 Withdrawn Rider RPS December 2021 June 2022 September 2022 140 127 Rider SNA ( 5) October 2021 July 2022 September 2022 107 N/A Rider SNA ( 5) October 2022 Pending September 2023 50 (57 ) Rider T1 (6) May 2022 July 2022 September 2022 706 (168 ) Rider U ( 7) June 2021 March 2022 April 2022 95 15 Rider U ( 8) June 2022 Pending April 2023 74 (21 ) Rider US-2 October 2021 June 2022 September 2022 11 2 Rider US-3 August 2021 March 2022 June 2022 50 12 Rider US-3 August 2022 Pending June 2023 40 (10 ) Rider US-4 August 2021 March 2022 June 2022 15 5 Rider US-4 August 2022 Pending June 2023 17 2 Rider W June 2022 Pending April 2023 106 (15 ) Rider W June 2022 Pending April 2024 109 3 DSM Riders ( 9) December 2021 August 2022 September 2022 91 17 (1) Associated with solar generation and energy storage projects approved in March 2022, solar generation projects approved in April 2021 and certain small-scale solar projects. (2) Associated with solar generation and energy storage projects requested for approval in October 2022 and certain small-scale solar projects in addition to previously approved Rider CE projects. (3) In August 2022, Virginia Power filed a petition for limited reconsideration relating to a performance standard for operation of the CVOW Commercial Project included in the Virginia Commission’s August order. The Virginia Commission granted reconsideration and suspended in part the August order pending its reconsideration with Rider OSW approved on an interim basis. (4) In January 2022, Virginia Power filed a motion to withdraw its application as a result of the announcement by the Governor of Virginia that he intends to withdraw Virginia from RGGI. The Virginia Commission granted Virginia Power’s motion in April 2022. See additional discussion below. (5) Virginia Power also requested approval of cost recovery of approximately $1.2 billion through Rider SNA for the first phase of nuclear life extension program which includes investments through 2024. In April 2022, Virginia Power, the Virginia Commission staff and certain interested parties filed a proposed stipulation recommending that costs incurred after February 2022 associated with the first phase of the nuclear life extension program for North Anna be deferred and requested for recovery in a subsequent Rider SNA filing. (6) Consists of $482 million for the transmission component of Virginia Power’s base rates and $224 million for Rider T1. (7) Consists of $ 60 35 (8) As amended in June 2022, application consists of $74 million for previously approved phases of Rider U. (9) Associated with an additional nine new energy efficiency programs with a $140 million cost cap, with the ability to exceed the cost cap by no more than 15%. In May 2022, Virginia Power filed a petition with the Virginia Commission requesting a suspension of Rider RGGI approved in August 2021. Virginia Power also requested that RGGI compliance costs incurred and unrecovered through July 2022 be recovered through existing base rates in effect during the period incurred. The Virginia Commission approved the request in June 2022. In the second quarter of 2022, Virginia Power recorded a charge of $180 million ($134 million after-tax) in impairment of assets and other charges for the amount deemed recovered through base rates through June 30, 2022, including the impact of certain non-jurisdictional customers which follow Virginia Power’s jurisdictional rate methodology.

In February 2020, the North Carolina Commission issued its final order relating to base rates. In July 2020, Virginia Power filed a notice of appeal and exceptions to the Supreme Court of North Carolina, arguing that the North Carolina Commission committed reversible error on certain issues relating to the ratemaking treatment of certain coal ash remediation costs. In June 2022, the Supreme Court of North Carolina affirmed the North Carolina Commission’s order. Virginia Power North Carolina Fuel Filing In August 2022, Virginia Power submitted its annual filing to the North Carolina Commission to adjust the fuel component of its electric rates. Virginia Power updated its filing in October 2022 to reflect the increased commodity cost of fuel and proposed a total $ 107 PSNC Rider D Rider D allows PSNC to recover from customers all prudently incurred gas costs and the related portion of uncollectible expenses as well as losses on negotiated gas and transportation sales. In May 2022, PSNC submitted a filing with the North Carolina Commission for a $56 million gas cost increase. The North Carolina Commission approved the filing in May 2022 with rates effective June 2022. In September 2022, PSNC submitted a filing with the North Carolina Commission for a $126 million gas cost increase. The North Carolina Commission approved the filing in September 2022 with rates effective October 2022. PSNC Customer Usage Tracker PSNC utilizes a customer usage tracker, a decoupling mechanism, which allows it to adjust its base rates semi-annually for residential and commercial customers based on average per customer consumption. In September 2022, PSNC submitted a filing with the North Carolina Commission for a $46 million increase relating to the customer usage tracker. The North Carolina Commission approved the filing in September 2022 with rates effective October 2022. South Carolina Regulation DSM Programs DESC has approval for a DSM rider through which it recovers expenditures related to its DSM programs. In January 2022, DESC filed an application with the South Carolina Commission seeking approval to recover $60 million of costs and net lost revenues associated with these programs, along with an incentive to invest in such programs. In April 2022 , the South Carolina Commission approved the request, effective with the first billing cycle of May 2022. Cost of Fuel DESC’s retail electric rates include a cost of fuel component approved by the South Carolina Commission which may be adjusted periodically to reflect changes in the price of fuel purchased by DESC. In August 2022, DESC filed an application with the South Carolina Commission seeking a mid-period adjustment to increase the base fuel component of retail electric rates for the recovery of electric fuel costs. If approved, the increase of the base fuel cost component is expected to be effective with the first billing cycle of January 2023. The estimated annual increase is $399 million. This matter is pending. Natural Gas Rates In June 2022, DESC filed with the South Carolina Commission its monitoring report for the 12-month period ended March 31, 2022 with a total revenue requirement of $553 million. This represents a $129 million overall annual increase to its natural gas rates including a $16 million base rate increase under the terms of the Natural Gas Rate Stabilization Act effective with the first billing cycle of November 2022. In October 2022, the South Carolina Commission issued an order approving a total revenue requirement of $549 million effective with the first billing cycle of November 2022. This represents a $125 million overall annual increase to DESC’s natural gas rates including a $12 million base rate increase under the terms of the Natural Gas Rate Stabilization Act. Ohio Regulation PIR Program In 2008, East Ohio began PIR, aimed at replacing approximately 25% of its pipeline system. In April 2022, the Ohio Commission approved an extension of East Ohio’s PIR program for capital investments through 2026 with continuation of 3% increases of annual capital expenditures per year. In June 2022, the Ohio Commission approved East Ohio’s application to adjust the PIR cost recovery rates for 2021 costs. The filing reflects gross plant investment for 2021 of $225 million, cumulative gross plant investment of $2.2 billion and a revenue requirement of $273 million. CEP Program In 2011, East Ohio began CEP which enables East Ohio to defer depreciation expense, property tax expense and carrying costs associated with CEP investments. In April 2022, certain parties filed an appeal with the Supreme Court of Ohio appealing the Ohio Commission’s December 2020 order establishing the CEP rider, including the rate of return utilized in determining the revenue requirement. This matter is pending. In February 2022, the Ohio Commission approved adjustments to CEP cost recovery rates for 2019 and 2020 costs. The approved rates reflect gross plant investment for 2019 and 2020 of $231 million, cumulative gross plant investment of $952 million and a revenue requirement of $118 million. The Ohio Commission also ordered that East Ohio should file its next base rate case by October 2023. In November 2022, the Ohio Commission approved adjustments to CEP cost recovery rates for 2021 costs. The approved rates reflect gross plant investment for 2021 of $146 million, cumulative gross plant investment of $1.1 billion and a revenue requirement of $131 million. PIPP Plus Program 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 2022, East Ohio’s annual update of the PIPP rider filed in May 2022 with the Ohio Commission was approved. The revised rider rate reflects recovery over the twelve-month period from July 2022 through June 2023 of projected deferred program costs of approximately $22 million from April 2022 through June 2023, net of over-recovery of accumulated arrearages of approximately $4 million as of March 31, 2022. 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 writeoffs of uncollectible amounts. In July 2022, the Ohio Commission approved East Ohio’s application to adjust its UEX rider to reflect an annual revenue requirement of $20 million to provide for recovery of an under-recovered accumulated bad debt expense of $7 million as of March 31, 2022, and recovery of net bad debt expense projected to total $13 million for the twelve-month period ending March 2023. West Virginia Regulation West Virginia Base Rate Case In September 2020, Hope filed its base rate case and schedules with the West Virginia Commission. Hope proposed a non-fuel, base rate increase of $28 million. The base rate increase was proposed to recover the significant investment in distribution infrastructure and costs associated with the acquisition of over 2,000 miles of gathering assets, both for the benefit of West Virginia customers. The proposed rates would provide for an ROE of 10.25% compared to the authorized ROE of 9.45%. In July 2021, the West Virginia Commission approved a non-fuel, base rate increase of $13 million for rates effective July 2021 with an ROE of 9.54%. In August 2021, Hope filed a petition for reconsideration with the West Virginia Commission regarding certain return calculations included in the July 2021 approval order. In June 2022, the West Virginia Commission issued an order resolving this petition without material modification to Hope’s base rates. Utah Regulation Utah Base Rate Case In May 2022, Questar Gas filed its base rate case and schedules with the Utah Commission. Questar Gas proposed a non-fuel, base rate increase of $71 million effective January 2023. The base rate increase was proposed to recover the significant investment in distribution infrastructure for the benefit of Utah customers. The proposed rates would provide for an ROE of 10.3% compared to the currently authorized ROE of 9.5%. This matter is pending. Purchased Gas In July 2022, the Utah Commission approved Questar Gas’ request for a $94 million gas cost increase with rates effective August 2022. In October 2022, the Utah Commission approved Questar Gas’ request for a $128 million gas cost increase with rates effective November 2022. |

Debt Disclosure [Abstract] | |
Significant Financing Transactions | Note 16. 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 Energy utilizes cash and letters of credit to fund collateral requirements. Collateral requirements are impacted by commodity prices, hedging levels, Dominion Energy’s credit ratings and the credit quality of its counterparties. Other than the items discussed below, there have been no significant changes regarding the Companies’ credit facilities and short-term debt as described in Note 17 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. Dominion Energy Dominion Energy’s short-term financing is supported by its $6.0 billion joint revolving credit facility that provides for a discount in the pricing of certain annual fees and amounts borrowed by Dominion Energy under the facility if Dominion Energy achieves certain annual renewable electric generation and diversity and inclusion objectives. At September 30, 2022, Dominion Energy’s commercial paper and letters of credit outstanding, as well as its capacity available under the credit facility, were as follows: Facility Limit Outstanding Commercial Paper Outstanding Letters of Credit Facility Capacity Available (millions) Joint revolving credit facility ( 1) $ 6,000 $ 2,600 $ 251 $ 3,149 (1) This credit facility matures in June 2026, with the potential to be extended by the borrowers to June 2028, and can be used by the borrowers under the credit facility to support bank borrowings and the issuance of commercial paper, as well as to support up to a combined $2.0 billion of letters of credit. DESC and Questar Gas’ short-term financings are supported through access as co-borrowers to the joint revolving credit facility discussed above with the Companies. At September 30, 2022, the sub-limits for DESC and Questar Gas were $500 million and $250 million, respectively. In addition to the credit facility mentioned above, Dominion Energy also has a credit facility which allows Dominion Energy to issue up to approximately $30 million in letters of credit and was scheduled to mature in June 2022 June 2025 June 2024 Dominion Energy has an effective shelf registration statement with the SEC for the sale of up to $3.0 billion of variable denomination floating rate demand notes, called Dominion Energy Reliability SM At September 30, 2022 and December 31, 2021, Dominion Energy’s Consolidated Balance Sheets include $343 million and $431 million, respectively, with respect to such notes presented within short-term debt. The proceeds are used for general corporate purposes and to repay debt. Virginia Power Virginia Power’s short-term financing is supported through its access as co-borrower to Dominion Energy’s $6.0 billion joint revolving credit facility. The credit facility can be used for working capital, as support for the combined commercial paper programs of the borrowers under the credit facility and for other general corporate purposes. At September 30, 2022, Virginia Power’s share of commercial paper and letters of credit outstanding under the joint revolving credit facility with Dominion Energy, Questar Gas and DESC was as follows: Facility Limit ( 1) Outstanding Commercial Paper Outstanding Letters of Credit (millions) Joint revolving credit facility ( 1) $ 6,000 $ 1,009 $ 180 (1) The full amount of the facility is available to Virginia Power, less any amounts outstanding to co-borrowers Dominion Energy, Questar Gas and DESC. The sub-limit for Virginia Power is set pursuant to the terms of the facility but can be changed at the option of the borrowers multiple times per year. At September 30, 2022, the sub-limit for Virginia Power was $1.75 billion. If Virginia Power has liquidity needs in excess of its sub-limit, the sub-limit may be changed or such needs may be satisfied through short-term intercompany borrowings from Dominion Energy. This credit facility matures in June 2026, with the potential to be extended by the borrowers to June 2028. The credit facility can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $2.0 billion (or the sub-limit, whichever is less) of letters of credit. Long-term Debt Unless otherwise noted, the proceeds of long-term debt issuances were used for general corporate purposes and/or to repay short-term debt. In January 2022, Virginia Power issued $600 million of 2.40% senior notes and $400 million of 2.95% senior notes that mature in 2032 and 2051, respectively. In April 2022, Virginia Power remarketed two series of tax-exempt bonds, with an aggregate outstanding principal of approximately $138 million to new investors. Both bonds will bear interest at a coupon of 1.65% until May 2024, after which they will bear interest at a market rate to be determined at that time. In May 2022, Dominion Energy borrowed $900 million under its Sustainability Revolving Credit Facility which matures in 2024 and bears interest at a variable rate. The proceeds from these borrowings were used to support environmental sustainability and social investment initiatives ($450 million) and for general corporate purposes ($450 million). In June 2022, Dominion Energy repaid $450 million borrowed for general corporate purposes. In May 2022, Virginia Power issued $600 million of 3.75% senior notes and $600 million of 4.625% senior notes that mature in 2027 and 2052, respectively.

Derivative Restructuring In June 2020, Dominion Energy amended a portfolio of interest rate swaps with a notional value of $2.0 billion, extending the mandatory termination dates, as discussed in Note 18 to the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. In August 2022, Dominion Energy settled certain of the outstanding interest rate swaps which would have otherwise matured in December 2024, resulting in a $154 million reduction in other long-term debt. Preferred Stock Dominion Energy is authorized to issue up to 20 million shares of preferred stock, which may be designated into separate classes. At September 30, 2022, Dominion Energy had issued and outstanding 1.8 million shares of preferred stock, 0.8 million and 1.0 million of which were designated as the Series B Preferred Stock and the Series C Preferred Stock, respectively.

Other than as discussed below, there have been no significant changes to Dominion Energy’s Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock as described in Note 19 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. 2019 Corporate Units The 2019 Equity Units, initially issued in the form of 2019 Series A Corporate Units, are described in Note 19 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. Pursuant to the terms of the 2019 Equity Units, Dominion Energy conducted a final remarketing of substantially all shares of Series A Preferred Stock in May 2022 which resulted in the dividend rate for all shares of Series A Preferred Stock being reset to 1.75% for the June 2022 through August 2022 dividend period and 6.75% effective September 2022. The conversion rate on the Series A Preferred Stock did not increase as a result of the remarketing. In May 2022, Dominion Energy received a commitment from a financial institution to purchase up to 1.6 million shares of the Series A Preferred Stock in the final remarketing. Accordingly, following the settlement of the successful remarketing and approval from its Board of Directors in June 2022, Dominion Energy became obligated to redeem all outstanding shares of Series A Preferred Stock in September 2022. As such, effective June 2022, the Series A Preferred Stock was considered to be mandatorily redeemable and was classified as a current liability. In addition, Dominion Energy made a short-term deposit at the financial institution as described further in Note 10. Proceeds from the final remarketing were used on behalf of holders of 2019 Series A Corporate Units at the time of the remarketing to pay the purchase price to Dominion Energy for the issuance of its common stock under the stock purchase contracts included in such corporate units in June 2022. In September 2022, Dominion Energy redeemed all outstanding shares of Series A Preferred Stock for $1.6 billion. The stock purchase contract liability associated with Dominion Energy’s 2019 Equity Units was $44 million at December 31, 2021. Stock purchase contract payments of $44 million and $64 million were made during the nine months ended September 30, 2022 and 2021, respectively.

Commitments And Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Note 17. 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 that the Companies cannot estimate, 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 that 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. The Companies maintain various insurance programs, including general liability insurance coverage which provides coverage for personal injury or wrongful death cases. 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 Companies’ financial position, liquidity or results of operations. 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 meet applicable 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. Ozone Standards The EPA published final non-attainment designations for the October 2015 ozone standard in June 2018 with states required to develop plans to address the new standard. Certain states in which the Companies operate have developed plans, and had such plans approved or partially approved by the EPA, which are not expected to have a material impact on the Companies’ results of operations or cash flows. However, until implementation plans for the standard are developed and approved for all states in which the Companies operate, the Companies are unable to predict whether or to what extent the new rules will ultimately require additional controls. The expenditures required to implement additional controls could have a material impact on the Companies’ results of operations and cash flows. ACE Rule In July 2019, the EPA published the final rule informally referred to as the ACE Rule, as a replacement for the Clean Power Plan. The ACE Rule regulated GHG emissions from existing coal-fired power plants pursuant to Section 111(d) of the CAA and required states to develop plans by July 2022 establishing unit-specific performance standards for existing coal-fired power plants. In January 2021, the U.S. Court of Appeals for the D.C. Circuit vacated the ACE Rule and remanded it to the EPA. This decision would take effect upon issuance of the court’s mandate. In March 2021, the court issued a partial mandate vacating and remanding all parts of the ACE Rule except for the portion of the ACE Rule that repealed the Clean Power Plan. In October 2021, the U.S. Supreme Court agreed to hear a challenge of the U.S. Court of Appeals for the D.C. Circuit’s decision on the ACE Rule. In June 2022, the U.S. Supreme Court reversed the D.C. Circuit’s decision on the ACE Rule and remanded the case back to the D.C. Circuit. Until the case is resolved by the D.C. Circuit and/or the EPA issues new rulemaking, the Companies cannot predict an impact to its operations, financial condition and/or cash flows. Carbon Regulations In August 2016, the EPA issued a draft rule proposing to reaffirm that a source’s obligation to obtain a PSD or Title V permit for GHGs is triggered only if such permitting requirements are first triggered by non-GHG, or conventional, pollutants that are regulated by the New Source Review program, and exceed a significant emissions rate of 75,000 tons per year of CO 2 In December 2018, the EPA proposed revised Standards of Performance for Greenhouse Gas Emissions from New, Modified, and Reconstructed Stationary Sources. The proposed rule would amend the previous determination that the best system of emission reduction for newly constructed coal-fired steam generating units is no longer partial carbon capture and storage. Instead, the proposed revised best system of emission reduction for this source category is the most efficient demonstrated steam cycle (e.g., supercritical steam conditions for large units and subcritical steam conditions for small units) in combination with best operating practices. The proposed revision to the performance standards for coal-fired steam generating units remains pending. Until the EPA ultimately takes final action on this rulemaking, the Companies cannot predict the impact to their results of operations, financial condition and/or cash flows. 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. Regulation 316(b) 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 DESC is conducting studies and implementing plans as required by the rule to determine appropriate intake structure modifications at certain facilities to ensure compliance with this rule. While the impacts of this rule could be material to the Companies’ results of operations, financial condition and/or cash flows, the existing regulatory frameworks in South Carolina and Virginia provide rate recovery mechanisms that could substantially mitigate any such impacts for the regulated electric utilities. Effluent Limitations Guidelines In September 2015, the EPA released a final rule to revise the Effluent Limitations Guidelines for the Steam Electric Power Generating Category. The final rule established updated standards for wastewater discharges that apply primarily at coal and oil steam generating stations. Affected facilities are required to convert from wet to dry or closed cycle coal ash management, improve existing wastewater treatment systems and/or install new wastewater treatment technologies in order to meet the new discharge limits. In April 2017, the EPA granted two separate petitions for reconsideration of the Effluent Limitations Guidelines final rule and stayed future compliance dates in the rule. Also in April 2017, the U.S. Court of Appeals for the Fifth Circuit granted the EPA’s request for a stay of the pending consolidated litigation challenging the rule while the EPA addresses the petitions for reconsideration. In September 2017, the EPA signed a rule to postpone the earliest compliance dates for certain waste streams regulations in the Effluent Limitations Guidelines final rule from November 2018 to November 2020; however, the latest date for compliance for these regulations was December 2023 . . While the impacts of this rule could be material to the Companies’ results of operations, financial condition and/or cash flows, the existing regulatory frameworks in South Carolina and Virginia provide rate recovery mechanisms that could substantially mitigate any such impacts for the regulated electric utilities. Waste Management and Remediation The operations of the Companies are subject to a variety of state and federal laws and regulations governing the management and disposal of solid and hazardous waste, and release of hazardous substances associated with current and/or historical operations. The CERCLA, as amended, and similar state laws, may impose joint, several and strict liability for cleanup on potentially responsible parties who owned, operated or arranged for disposal at facilities affected by a release of hazardous substances. In addition, many states have created programs to incentivize voluntary remediation of sites where historical releases of hazardous substances are identified and property owners or responsible parties decide to initiate cleanups. From time to time, the Companies may be identified as a potentially responsible party in connection with the alleged release of hazardous substances or wastes at a site. Under applicable federal and state laws, the Companies could be responsible for costs associated with the investigation or remediation of impacted sites, or subject to contribution claims by other responsible parties for their costs incurred at such sites. The Companies also may identify, evaluate and remediate other potentially impacted sites under voluntary state programs. Remediation costs may be subject to reimbursement under the Companies’ insurance policies, rate recovery mechanisms, or both. Except as described below, the Companies do not believe these matters will have a material effect on results of operations, financial condition and/or cash flows. Dominion Energy has determined that it is associated with former manufactured gas plant sites, including certain sites associated with Virginia Power. At 13 sites associated with Dominion Energy remediation work has been substantially completed under federal or state oversight. Where required, the sites are following state-approved groundwater monitoring programs. Dominion Energy commenced remediation activities at one site in the second quarter of 2022. In addition, Dominion Energy has proposed remediation plans with one site at Virginia Power and expects to commence remediation activities in 2023 depending on receipt of final permits and approvals. At September 30, 2022 and December 31, 2021, Dominion Energy had $47 million and $45 million, respectively, and Virginia Power had $25 million at both periods, of reserves recorded. Dominion Energy is associated with 12 additional sites, including two associated with Virginia Power, which are not under investigation by any state or federal environmental agency nor the subject of any current or proposed plans to perform remediation activities. Due to the uncertainty surrounding such sites, the Companies are unable to make an estimate of the potential financial statement impacts. 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. SCANA Legal Proceedings The following describes certain legal proceedings involving Dominion Energy, SCANA or DESC relating primarily to events occurring before closing of the SCANA Combination. In addition, certain legal matters which have been resolved 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, 2021. No reference to, or disclosure of, any proceeding, item or matter described below shall be construed as an admission or indication that such proceeding, item or matter is material. For certain of these matters, and unless otherwise noted therein, Dominion Energy is unable to estimate a reasonable range of possible loss and the related financial statement impacts, but for any such matter there could be a material impact to its results of operations, financial condition and/or cash flows. For the matters for which Dominion Energy is able to reasonably estimate a probable loss, Dominion Energy’s Consolidated Balance Sheets at September 3 0 , 202 2 and December 31, 202 1 include reserves of $ 96 million and $ million, respectively, included in other current liabilities, and insurance receivables of $ 68 million and $ million , respectively , included within other receivables. These balances at September 3 0 , 2022 and December 31, 2021 include $ 68 million and $ 85 million, respectively, of offsetting reserves and insurance receivables related to personal injury or wrongful death cases which are currently pending. During both the three and nine months ended September 30, 2022, charges included in Dominion Energy’s Consolidated Statements of Income were inconsequential . During the nine months ended September 3 0 , 202 1 , Dominion Energy’s Consolidated Statements of Income include charges of $ million ($ million after-tax) , included within impairment of assets and other charges. SCANA Shareholder Litigation In September 2017, a shareholder derivative action was filed against certain former executive officers and directors of SCANA in the State Court of Common Pleas in Richland County, South Carolina (the State Court Derivative Case). In September 2018, this action was consolidated with another action in the Business Court Pilot Program in Richland County. The plaintiffs allege, among other things, that the defendants breached their fiduciary duties to shareholders by their gross mismanagement of the NND Project, and that the defendants were unjustly enriched by bonuses they were paid in connection with the project. In January 2019, the defendants filed a motion to dismiss the consolidated action. In February 2019, one action was voluntarily dismissed. In March 2020, the court denied the defendants’ motion to dismiss. In April 2020, the defendants filed a notice of appeal with the South Carolina Court of Appeals and a petition with the Supreme Court of South Carolina seeking appellate review of the denial of the motion to dismiss. In June 2020, the plaintiffs filed a motion to dismiss the appeal with the South Carolina Court of Appeals, which was granted in July 2020. In August 2020, the Supreme Court of South Carolina denied the defendants’ petition seeking appellate review. Also in August 2020, the defendants filed a petition for rehearing with the South Carolina Court of Appeals relating to the July 2020 ruling by the court, which was denied in October 2020. In November 2020, SCANA filed a petition of certiorari with the Supreme Court of South Carolina seeking appellate review of the denial of SCANA’s motion to dismiss. This petition was denied in June 2021. Also in June 2021, the parties reached an agreement in principle in the amount of $33 million to resolve this matter, subject to court approval. This settlement was reached in contemplation of and to be utilized to satisfy a portion of the Federal Court Merger Case and the State Court Merger Case discussed below. In November 2021, the parties executed a settlement agreement and filed with the State Court of Common Pleas in Richland County, South Carolina for approval. In June 2022, the State Court of Common Pleas in Richland County, South Carolina issued final approval of the settlement agreement with the funds utilized to satisfy a portion of the State Court Merger Case as discussed below. In January 2018, a purported class action was filed against SCANA, Dominion Energy and certain former executive officers and directors of SCANA in the State Court of Common Pleas in Lexington County, South Carolina (the City of Warren Lawsuit). The plaintiff alleges, among other things, that defendants violated their fiduciary duties to shareholders by executing a merger agreement that would unfairly deprive plaintiffs of the true value of their SCANA stock, and that Dominion Energy aided and abetted these actions. Among other remedies, the plaintiff seeks to enjoin and/or rescind the merger. In February 2018, a purported class action was filed against Dominion Energy and certain former directors of SCANA and DESC in the State Court of Common Pleas in Richland County, South Carolina (the Metzler Lawsuit). The allegations made and the relief sought by the plaintiffs are substantially similar to that described for the City of Warren Lawsuit. In September 2019, the U.S. District Court for the District of South Carolina granted the plaintiffs’ motion to consolidate the City of Warren Lawsuit and the Metzler Lawsuit (the Federal Court Merger Case). In October 2019, the plaintiffs filed an amended complaint against certain former directors and executive officers of SCANA and DESC, which stated substantially similar allegations to those in the City of Warren Lawsuit and the Metzler Lawsuit as well as an inseparable fraud claim. In November 2019, the defendants filed a motion to dismiss. In April 2020, the U.S. District Court for the District of South Carolina denied the motion to dismiss. In May 2020, SCANA filed a motion to intervene, which was denied in August 2020. In September 2020, SCANA filed a notice of appeal with the U.S. Court of Appeals for the Fourth Circuit. In June 2021, the parties reached an agreement in principle in the amount of $63 million to resolve this matter as well as the State Court Merger Case described below, subject to court approval. This settlement was reached in contemplation of and to be partially satisfied by the State Court Derivative Case settlement described above. In November 2021, the parties executed a settlement agreement, as described above relating to this matter as well as the State Court Derivative Case and the State Court Merger Case, and filed with the State Court of Common Pleas in Richland County, South Carolina for approval. In June 2022, this case was dismissed in connection with the final approval by the State Court of Common Pleas in Richland County, South Carolina of the settlement agreement. In May 2019, a case was filed against certain former executive officers and directors of SCANA in the State Court of Common Pleas in Richland County, South Carolina (the State Court Merger Case). The plaintiff alleges, among other things, that the defendants breached their fiduciary duties to shareholders by their gross mismanagement of the NND Project, were unjustly enriched by the bonuses they were paid in connection with the project and breached their fiduciary duties to secure and obtain the best price for the sale of SCANA. Also in May 2019, the case was removed to the U.S. District Court of South Carolina by the non-South Carolina defendants. In June 2019, the plaintiffs filed a motion to remand the case to state court. In January 2020, the case was remanded to state court. In February 2020, the defendants filed a motion to dismiss. In June 2021, the parties reached an agreement in principle as described above relating to this matter as well as the Federal Court Merger Case and the State Court Derivative Case. In November 2021, the parties executed a settlement agreement, as described above relating to this matter as well as the State Court Derivative Case and the Federal Court Merger Case, and filed with the State Court of Common Pleas in Richland County, South Carolina for approval. In June 2022, the State Court of Common Pleas in Richland County, South Carolina issued final approval of the settlement agreement. Also in June 2022, Dominion Energy utilized the $33 million of insurance proceeds from the State Court Derivative Case settlement, the issuance of 0.4 million shares of its common stock and paid $2 million in cash to satisfy its obligations under the settlement agreement. Employment Class Actions and Indemnification In August 2017, a case was filed in the U.S. District Court for the District of South Carolina on behalf of persons who were formerly employed at the NND Project. In July 2018, the court certified this case as a class action. In February 2019, certain of these plaintiffs filed an additional case, which case has been dismissed and the plaintiffs have joined the case filed August 2017. The plaintiffs allege, among other things, that SCANA, DESC, Fluor Corporation and Fluor Enterprises, Inc. violated the Worker Adjustment and Retraining Notification Act in connection with the decision to stop construction at the NND Project. The plaintiffs allege that the defendants failed to provide adequate advance written notice of their terminations of employment and are seeking damages, which could be as much as $100 million for 100% of the NND Project. In January 2021, the U.S. District Court for the District of South Carolina granted summary judgment in favor of SCANA, DESC, Fluor Corporation and Fluor Enterprises, Inc. In February 2021, the plaintiffs filed a notice of appeal with the U.S. Court of Appeals for the Fourth Circuit. In November 2021, the U.S Court of Appeals for the Fourth Circuit affirmed the lower court ruling. In March 2022, the deadline to file an appeal to the Supreme Court of the United States expired. In September 2018, a case was filed in the State Court of Common Pleas in Fairfield County, South Carolina by Fluor Enterprises, Inc. and Fluor Daniel Maintenance Services, Inc. against DESC and Santee Cooper. The plaintiffs make claims for indemnification, breach of contract and promissory estoppel arising from, among other things, the defendants' alleged failure and refusal to defend and indemnify the Fluor defendants in the aforementioned case. As a result of the ruling in favor of the defendants in the aforementioned case, DESC was able to resolve Fluor’s claims for an inconsequential amount. Governmental Proceedings and Investigations In June 2018, DESC received a notice of proposed assessment of approximately $410 million, excluding interest, from the SCDOR following its audit of DESC’s sales and use tax returns for the periods September 1, 2008 through December 31, 2017. The proposed assessment, which includes 100% of the NND Project, is based on the SCDOR’s position that DESC’s sales and use tax exemption for the NND Project does not apply because the facility will not become operational. In December 2020, the parties reached an agreement in principle in the amount of $165 million to resolve this matter. In June 2021, the parties executed a settlement agreement which allows DESC to fund the settlement amount through a combination of cash, shares of Dominion Energy common stock or real estate with an initial payment of at least $43 million in shares of Dominion Energy common stock. In August 2021, Dominion Energy issued 0.6 million shares of its common stock to satisfy DESC’s obligation for the initial payment under the settlement agreement. In May 2022, Dominion Energy issued an additional 0.9 million shares of its common stock to partially satisfy DESC’s remaining obligation under the settlement agreement. Nuclear Operations Nuclear Insurance Other than the items discussed below, there have been no significant changes regarding the Companies’ nuclear insurance as described in Note 23 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. During the second quarter of 2022, Dominion Energy reduced the levels of nuclear property insurance coverage for the reactor site at Summer from $2.75 billion to the NRC minimum requirement of $1.06 billion. As a result of this reduction in nuclear property insurance coverage, Dominion Energy’s maximum retrospective premium assessment for the current annual policy period was reduced to $65 million. Additionally, DESC maintains an excess property insurance policy with the European Mutual Association for Nuclear Insurance which provides coverage to Summer for property damage and outage costs resulting from an event of a non-nuclear origin. Dominion Energy reduced the levels of coverage from $415 million to $1 million. During the third quarter of 2022, the total liability protection per nuclear incident available to all participants in the Secondary Financial Protection Program increased from $13.5 billion to $13.7 billion. This increase does not impact Dominion Energy’s responsibility per active unit under the Price-Anderson Amendments Act of 1988. Spent Nuclear Fuel As discussed in Note 23 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021, the Companies entered into contracts with the DOE for the disposal of spent nuclear fuel under provisions of the Nuclear Waste Policy Act of 1982. Guarantees, Surety Bonds and Letters of Credit At September 30, 2022, Dominion Energy had issued four guarantees related to Cove Point, an equity method investment, in support of terminal services, transportation and construction. Two of the Cove Point guarantees have a cumulative maximum exposure of $1.9 billion while the other two guarantees have no maximum limit. No amounts related to these guarantees have been recorded. In addition, at September 30, 2022, Dominion Energy had issued an additional $20 million of guarantees, primarily to support third parties. No amounts related to these guarantees have been recorded. Dominion Energy also enters into guarantee arrangements on behalf of its consolidated subsidiaries, primarily to facilitate their commercial transactions with third parties. If any of these subsidiaries fail to perform or pay under the contracts and the counterparties seek performance or payment, Dominion Energy would be obligated to satisfy such obligation. To the extent that a liability subject to a guarantee has been incurred by one of Dominion Energy’s consolidated subsidiaries, that liability is included in the Consolidated Financial Statements. Dominion Energy 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 Energy 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 September 30, 2022, Dominion Energy had issued the following subsidiary guarantees: Maximum Exposure (millions) Commodity transactions (1) $ 2,514 Nuclear obligations (2) 243 Solar (3) 303 Other (4) 1,268 Total (5)(6) $ 4,328 (1) Guarantees related to commodity commitments of certain subsidiaries. These guarantees were provided to counterparties in order to facilitate physical and financial transaction related commodities and services. (2) Guarantees primarily related to certain DGI subsidiaries regarding all aspects of running a nuclear facility. (3) Includes guarantees to facilitate the development of solar projects. (4) Guarantees related to other miscellaneous contractual obligations such as leases, environmental obligations, construction projects and insurance programs. Also includes guarantees entered into by Dominion Energy RNG Holdings II, Inc. on behalf of a subsidiary to facilitate construction of renewable natural gas facilities. Due to the uncertainty of workers’ compensation claims, the parental guarantee has no stated limit. (5) Excludes Dominion Energy’s guarantee of an offshore wind installation vessel discussed in Note 15 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021 . (6) In July 2016, Dominion Energy signed an agreement with a lessor to construct and lease a new corporate office property in Richmond, Virginia. The lessor provided equity and obtained financing commitments from debt investors, totaling $365 million, which funded total project costs. The project became substantially complete in August 2019 at which point the facility was available for Dominion Energy’s use and the five-year Additionally, at September 30, 2022, Dominion Energy had purchased $248 million of surety bonds, including $172 million at Virginia Power, and authorized the issuance of letters of credit by financial institutions of $251 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 | Note 18. Credit Risk The Companies’ accounting policies for credit risk are discussed in Note 24 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. At September 30, 2022, Dominion Energy’s credit exposure totaled $133 million, primarily related to price risk management activities. Of this amount, investment grade counterparties, including those internally rated, represented 88%. No single counterparty, whether investment grade or non-investment grade, exceeded $45 million of exposure. At September 30, 2022, Virginia Power’s exposure related to wholesale customers totaled $17 million. Of this amount, investment grade counterparties, including those internally rated, represented 78%. No single counterparty, whether investment grade or non-investment grade, exceeded $4 million of exposure. Credit-Related Contingent Provisions Certain of Dominion Energy’s derivative instruments contain credit-related contingent provisions. These provisions require Dominion Energy 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 September 30, 2022 and December 31, 2021, Dominion Energy would have been required to post $189 million and $31 million, respectively, of additional 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 Energy had posted $124 million and $66 million of collateral at September 30, 2022 and December 31, 2021, respectively, related to derivative instruments with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. In addition, Dominion Energy had posted letters of credit as collateral with counterparties covering $53 million of fair value of derivative instruments in a liability position at September 30, 2022. 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 was $313 million and $97 million at September 30, 2022 and December 31, 2021, respectively, which does not include the impact of any offsetting asset positions. Certain of Virginia Power’s derivative instruments contain credit-related contingent provisions. These provisions require Virginia Power to provide collateral upon the occurrence of specific events, primarily a credit rate 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 September 30, 2022 and December 31, 2021, Virginia Power would have been required to post $58 million and $22 million, respectively, of additional collateral to its counterparties. The collateral that would be required to be posted includes the impacts of any offsetting asset position and any amounts already posted for derivatives and non-derivative contracts, per contractual terms. Virginia Power had posted $121 million and $54 million of collateral at September 30, 2022 and December 31, 2021, respectively, related to derivative instruments with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. In addition, Virginia Power had posted letters of credit as collateral with counterparties covering $53 million of fair value of derivative instruments in a liability position at September 30, 2022. 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 was $179 million and $76 million at September 30, 2022 and December 31, 2021, respectively, which does not include the impact of any offsetting asset positions.

Related Party Transactions [Abstract] | |
Related-Party Transactions | Note 19. Related-Party Transactions Virginia Power engages in related-party transactions primarily with other Dominion Energy subsidiaries (affiliates). Virginia Power’s 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 is included in Dominion Energy's consolidated federal income tax return and, where applicable, combined income tax returns for Dominion Energy are filed in various states. Dominion Energy’s transactions with equity method investments are described in Note 10. 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 forward commodity purchases, to manage commodity price risks associated with purchases of natural gas. At September 30, 2022, Virginia Power’s derivative assets and liabilities with affiliates were $64 million and $3 million, respectively. At December 31, 2021, Virginia Power’s derivative assets and liabilities with affiliates were $29 million and $6 million, respectively. See Note 9 for additional information. Virginia Power participates in certain Dominion Energy benefit plans described in Note 22 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021. At September 30, 2022 and December 31, 2021, amounts due to Dominion Energy associated with the Dominion Energy Pension Plan and included in other deferred credits and other liabilities in the Consolidated Balance Sheets were $576 million and $522 million, respectively. At September 30, 2022 and December 31, 2021, Virginia Power's amounts due from Dominion Energy associated with the Dominion Energy Retiree Health and Welfare Plan and included in other deferred charges and other assets in the Consolidated Balance Sheets were $493 million and $431 million, respectively. While Virginia Power has not been notified by Dominion Energy of any required contributions to be made in 2022, it anticipates that it may have to contribute approximately $175 million as a result of Dominion Energy’s contribution made to its qualified defined benefit pension plans in December 2021. DES 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. The financial statements for all years presented include costs for certain general, administrative and corporate expenses assigned by DES to Virginia Power on the basis of direct and allocated methods in accordance with Virginia Power’s services agreements with DES. Where costs incurred cannot be determined by specific identification, the costs are allocated based on the proportional level of effort devoted by DES resources that is attributable to the entity, determined by reference to number of employees, salaries and wages and other similar measures for the relevant DES service. Management believes the assumptions and methodologies underlying the allocation of general corporate overhead expenses are reasonable. Presented below are Virginia Power’s significant transactions with DES and other affiliates: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 (millions) Commodity purchases from affiliates $ 515 $ 219 $ 1,099 $ 526 Services provided by affiliates (1) 125 116 378 363 Services provided to affiliates 4 6 13 15 (1) Includes capitalized expenditures of $44 million and $39 million for the three months ended September 30, 2022 and 2021, respectively, and $122 million and $121 million for the nine months ended September 30, 2022 and 2021, respectively. Virginia Power has borrowed funds from Dominion Energy under short-term borrowing arrangements. There were $784 million and $699 million in short-term demand note borrowings from Dominion Energy as of September 30, 2022 and December 31, 2021, respectively. Virginia Power had no outstanding borrowings, net of repayments, under the Dominion Energy money pool for its nonregulated subsidiaries as of September 30, 2022 and December 31, 2021. Interest charges related to Virginia Power’s borrowings from Dominion Energy were inconsequential for both the three and nine months ended September 30, 2022 and 2021. There were no issuances of Virginia Power’s common stock to Dominion Energy for the three and nine months ended September 30, 2022 and 2021. |

Segment Reporting [Abstract] | |
Operating Segments | Note 21. Operating Segments The Companies are organized primarily on the basis of products and services sold in the U.S. A description of the operations included in the Companies’ primary operating segments is as follows: Primary Operating Segment Description of Operations Dominion Energy Virginia Power Dominion Energy Virginia Regulated electric distribution X X Regulated electric transmission X X Regulated electric generation fleet (1) X X Gas Distribution Regulated gas distribution and storage (2) X Dominion Energy South Carolina Regulated electric distribution X Regulated electric transmission X Regulated electric generation fleet X Regulated gas distribution and storage X Contracted Assets Nonregulated electric generation fleet (3) X Noncontrolling interest in Cove Point X (1) I ncludes Virginia Power’s non-jurisdictional generation operations. (2) Includes renewable natural gas operations as well as Wexpro’s gas development and production operations. (3) Includes solar generation facility development operations. In addition to the operating segments above, the Companies also report a Corporate and Other segment. Dominion Energy The Corporate and Other Segment of Dominion Energy includes its corporate, service company and other functions (including unallocated debt) as well as nonregulated retail energy marketing operations (prior to December 2021), including Dominion Energy’s noncontrolling interests in Wrangler (through March 2022) and Dominion Privatization.

Accounting Policies [Abstract] | |
Basis of Accounting | 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, 2021. In the Companies’ opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position at September 30, 2022, their results of operations and changes in equity for the three and nine months ended September 30, 2022 and 2021 and their cash flows for the nine months ended September 30, 2022 and 2021. Such adjustments are normal and recurring in nature unless otherwise noted. |
Estimates | 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. |
Consolidation | 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. Clearway’s ownership interest in Four Brothers and Three Cedars (through December 2021) and Terra Nova Renewable Partners’ 33% interest in certain Dominion Energy nonregulated solar projects (through December 2021) are reflected as noncontrolling interest in Dominion Energy’s Consolidated Financial Statements. See Note 10 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021 for additional information. |
Reclassifications | Certain amounts in the Companies’ 2021 Consolidated Financial Statements and Notes have been reclassified to conform to the 2022 presentation for comparative purposes; however, such reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows. Amounts disclosed for Dominion Energy are inclusive of Virginia Power, where applicable. There have been no significant changes from Note 2 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021, with the exception of the items described below. |
Cash, Restricted Cash and Equivalents | Cash, Restricted Cash and Equivalents Restricted Cash and Equivalents The following table provides a reconciliation of the total cash, restricted cash and equivalents reported within the Companies’ Consolidated Balance Sheets to the corresponding amounts reported within the Companies’ Consolidated Statements of Cash Flows for the nine months ended September 30, 2022 and 2021: Cash, Restricted Cash and Equivalents at End of Period Cash, Restricted Cash and Equivalents at Beginning of Period September 30, 2022 September 30, 2021 December 31, 2021 December 31, 2020 (millions) Dominion Energy Cash and cash equivalents (1) $ 163 $ 195 $ 283 $ 179 Restricted cash and equivalents (2)(3) 177 72 125 68 Cash, restricted cash and equivalents shown in the Consolidated Statements of Cash Flows $ 340 $ 267 $ 408 $ 247 Virginia Power Cash and cash equivalents $ 18 $ 38 $ 26 $ 35 Restricted cash and equivalents (3) 2 1 — — Cash, restricted cash and equivalents shown in the Consolidated Statements of Cash Flows $ 20 $ 39 $ 26 $ 35 (1) At September 30, 2021 and December 31, 2020, Dominion Energy had $15 million and $7 million of cash and cash equivalents included in current assets held for sale, respectively.

Property, Plant and Equipment | Property, Plant and Equipment In the first quarter of 2022, Virginia Power revised the depreciation rates for its assets to reflect the results of a new depreciation study. The change resulted in a decrease in depreciation expense in Virginia Power’s Consolidated Statements of Income of $15 million ($11 million after-tax) and $45 million ($33 million after-tax) for the three and nine months ended September 30, 2022, respectively, and an increase in Dominion Energy’s EPS of $0.01 and $0.04 for the three and nine months ended September 30, 2022, respectively. The revision is expected to decrease Virginia Power’s annual depreciation expense by approximately $60 million ($45 million after-tax) and increase Dominion Energy’s EPS by approximately $0.05. For the three and nine months ended September 30, 2022, Virginia Power recorded charges of $18 million ($14 million after-tax) and $60 million ($45 million after-tax), respectively, associated with dismantling certain coal- and oil-fired generating units retired before the end of their useful lives, recorded in impairment of assets and other charges (benefits) in its Consolidated Statements of Income. |
Asset Retirement Obligations | Asset Retirement Obligations In the second quarter of 2021, Dominion Energy revised its estimated cash flow projections associated with the recovery of spent nuclear fuel costs for its AROs associated with the decommissioning of Kewaunee. As a result, Dominion Energy recorded a charge of $44 million ($35 million after-tax) within other operations and maintenance expense in its Consolidated Statements of Income. |
Fair Value Measurements | The Companies enter into certain physical and financial forwards, futures and options, 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 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, certain forward market prices and implied price volatilities are considered unobservable. |
Regulatory Matters Involving Potential Loss Contingencies | 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 regulatory matters that the Companies cannot estimate, 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 that 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. |
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 that the Companies cannot estimate, 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 that 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. The Companies maintain various insurance programs, including general liability insurance coverage which provides coverage for personal injury or wrongful death cases. 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 Companies’ financial position, liquidity or results of operations. |
Guarantees, Surety Bonds and Letters of Credit | Dominion Energy also enters into guarantee arrangements on behalf of its consolidated subsidiaries, primarily to facilitate their commercial transactions with third parties. If any of these subsidiaries fail to perform or pay under the contracts and the counterparties seek performance or payment, Dominion Energy would be obligated to satisfy such obligation. To the extent that a liability subject to a guarantee has been incurred by one of Dominion Energy’s consolidated subsidiaries, that liability is included in the Consolidated Financial Statements. Dominion Energy 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 Energy currently believes it is unlikely that it would be required to perform or otherwise incur any losses associated with guarantees of its subsidiaries’ obligations. |
