COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Nature of Operations

Dominion Energy, headquartered in Richmond, Virginia, is one of the nation’s largest producers and distributors of energy. Dominion Energy’s operations are conducted through various subsidiaries, including Virginia Power. Dominion Energy’s operations also include DESC, regulated gas distribution operations primarily in the eastern and Rocky Mountain regions of the U.S., nonregulated electric generation and a noncontrolling interest in Cove Point.

In connection with the comprehensive business review announced in November 2022, Dominion Energy entered into agreements in September 2023 to sell all of its regulated gas distribution operations, except for DESC’s, to Enbridge. In addition, Dominion Energy completed the sale in September 2023 of its remaining 50% noncontrolling partnership interest in Cove Point to BHE under the agreement entered in July 2023. As discussed in Notes 3 and 10, these operations are classified as discontinued operations and held for sale in Dominion Energy’s Consolidated Financial Statements. Subsequently in September 2023, Dominion Energy revised its primary operating segments as discussed in Note 21. Dominion Energy’s Consolidated Financial Statements and Notes have been recast to reflect these changes in presentation.

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, 2022.

In the Companies’ opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position at March 31, 2023, and their results of operations, changes in equity and cash flows for the three months ended March 31, 2023 and 2022. 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.

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’ 2022 Consolidated Financial Statements and Notes have been reclassified to conform to the 2023 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, 2022, with the exception of the items described below.

In September 2023, Dominion Energy entered into an agreement with Enbridge for the East Ohio Transaction, which includes the sale of East Ohio and is valued at approximately $6.6 billion, consisting of a purchase price of approximately $4.3 billion in cash and approximately $2.3 billion of assumed indebtedness. The purchase price will be subject to customary post-closing adjustments, including adjustments for cash, indebtedness, net working capital, capital expenditures and net regulatory assets and liabilities. Closing of the East Ohio Transaction is not conditioned upon the closing of the PSNC or Questar Gas Transactions. The sale will be treated as a stock sale for tax purposes and is expected to close in 2024, subject to clearance or approval under or by the Hart-Scott-Rodino Act, CFIUS and FCC as well as other customary closing and regulatory conditions. In November 2023, the waiting period under the Hart-Scott-Rodino Act expired. Also in November 2023, Dominion Energy submitted its initial filing request for approval by CFIUS.

The East Ohio Transaction is subject to termination by either party if not completed by September 2024, subject to a potential three-month extension for receipt of regulatory approvals, with a termination fee of $155 million due to Dominion Energy under certain conditions. Based on the recorded balances at September 30, 2023, Dominion Energy expects to recognize a pre-tax gain of approximately $20 million ($20 million after-tax loss) upon closing, including the write-off of $1.5 billion of goodwill which is not deductible for tax purposes but excluding the effects of final closing adjustments.

In the first quarter of 2022, Dominion Energy entered into an agreement to sell 100% of the equity interests in Hope in a stock sale for income tax purposes. Upon meeting the classification as held for sale, Dominion Energy established $87 million of deferred tax liabilities reflecting the excess of the financial reporting basis over the tax basis in Hope’s stock. These deferred taxes reversed upon closing of the sale in August 2022 and became a component of current income tax expense on the sale. See Note 3 to the Consolidated Financial Statements in Dominion Energy’s Annual Report on Form 10-K for the year ended December 31, 2022 for additional information regarding the sale of Hope.

As of March 31, 2023, there have been no material changes in the Companies’ unrecognized tax benefits or possible changes that could reasonably be expected to occur during the next twelve months. 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.

Note 8. Fair Value Measurements

The Companies’ fair value measurements are made in accordance with the policies discussed in Note 2 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2022. 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.

26

The following table presents the Companies' quantitative information about Level 3 fair value measurements at March 31, 2023. The range and weighted average are presented in dollars for market price inputs and percentages for price volatility.

(1)Averages weighted by volume.

(2)Includes basis.

(3)Represents market prices beyond defined terms for Levels 1 and 2.

(4)Represents volatilities unrepresented in published markets.

Sensitivity of the fair value measurements to changes in the significant unobservable inputs is as follows:

Significant Unobservable Inputs	Position	Change to Input	Impact on Fair Value Measurement
Market price	Buy	Increase (decrease)	Gain (loss)
Market price	Sell	Increase (decrease)	Loss (gain)
Price volatility	Buy	Increase (decrease)	Gain (loss)
Price volatility	Sell	Increase (decrease)	Loss (gain)

Nonrecurring Fair Value Measurements

See Note 10 for information regarding nonrecurring fair value measurements associated with Dominion Energy’s noncontrolling ownership interest in Dominion Privatization.

In the first quarter of 2023, Dominion Energy recorded a charge of $91 million ($68 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income to adjust a corporate office building down to its estimated fair value, using a market approach, of $35 million. The valuation is considered a Level 3 fair value measurement as it is based on unobservable inputs due to limited comparable market activity. The corporate office building is reflected in the Corporate and Other segment and presented as held for sale in Dominion Energy’s Consolidated Balance Sheets at March 31, 2023.

Dominion Energy had less than $1 million of unrealized gains and losses included in earnings in the Level 3 fair value category related to assets/liabilities still held at the reporting date for the three months ended March 31, 2023 and no such amounts for the three months ended March 31, 2022. Virginia Power had no such amounts for the three months ended March 31, 2023 and 2022.

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, 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:

	Dominion Energy				Virginia Power
	Carrying Amount		Estimated Fair Value(1)		Carrying Amount		Estimated Fair Value(1)
(millions)
March 31, 2023
Long-term debt(2)	$	41,920	$	39,771	$	16,400	$	15,314
Supplemental credit facility borrowings		900		900
Junior subordinated notes(2)		1,387		1,350
December 31, 2022
Long-term debt(2)	$	39,680	$	36,426	$	15,616	$	14,067
Supplemental credit facility borrowings		450		450
Junior subordinated notes(2)		1,387		1,340

(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. Additionally, the Dominion Energy carrying amount includes portions classified as held for sale and presented in current liabilities held for sale and noncurrent liabilities held for sale.

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, 2022. See Note 8 in this report for additional information about fair value measurements and associated valuation methods for derivatives.

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.

Equity Method Investments

Dominion Energy recorded equity earnings on its investments of $2 million and $6 million for the three months ended March 31, 2023 and 2022, respectively, in other income (expense) in its Consolidated Statements of Income. In addition, Dominion Energy recorded equity earnings of $76 million and $72 million for the three months ended March 31, 2023 and 2022, respectively, in discontinued operations, including amounts primarily related to its investments in Cove Point and Atlantic Coast Pipeline discussed below. Dominion Energy received distributions of $85 million and $76 million for the three months ended March 31, 2023 and 2022, respectively. Dominion Energy made contributions of $10 million and $74 million for the three months ended March 31, 2023 and 2022, respectively. At March 31, 2023 and December 31, 2022, the net difference between the carrying amount of Dominion Energy’s investments and its share of underlying equity in net assets was $217 million and $223 million, respectively. At March 31, 2023, these differences are primarily comprised of $9 million of equity method goodwill that is not being amortized and a $213 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, 2022, these differences are comprised of $9 million of equity method goodwill that is not being amortized, $215 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 $(1) million basis difference primarily attributable to capitalized interest.

Cove Point

Prior to the completion of the sale in September 2023 as discussed below, Dominion Energy held a 50% noncontrolling limited partnership interest in Cove Point which was 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, 2022.

36

Dominion Energy recorded distributions from Cove Point of $83 million and $76 million for the three months ended March 31, 2023 and 2022, respectively.

In July 2023, Dominion Energy entered into an agreement to sell its 50% noncontrolling limited partnership interest in Cove Point to BHE for cash consideration of $3.3 billion which closed in September 2023 after all customary closing and regulatory conditions were satisfied, including clearance under the Hart-Scott-Rodino Act and approval from the DOE. The sale is treated as an asset sale for tax purposes. In addition, Dominion Energy received proceeds of $199 million from the settlement of related interest rate derivatives. In connection with closing, Dominion Energy utilized proceeds, as required, to repay DECP Holding's term loan secured by its noncontrolling interest in Cove Point, which had an outstanding balance of $2.2 billion, and $750 million of outstanding borrowings under Dominion Energy’s two $600 million 364-day term loan facilities entered in July 2023.

In September 2023, as a result of Dominion Energy entering agreements for the East Ohio, PSNC and Questar Gas Transactions, Dominion Energy’s 50% noncontrolling limited partnership interest in Cove Point also met the requirements to be presented as discontinued operations and held for sale as both disposition activities were executed in connection with Dominion Energy’s comprehensive business review announced in November 2022. In addition, interest expense associated with DECP Holding's term loan secured by its noncontrolling interest in Cove Point have been classified as discontinued operations. As a result, the previously reported amounts have been recast to reflect this presentation.

Amounts presented within discontinued operations within Dominion Energy’s Consolidated Statements of Income for the three months ended March 31, 2023 include $76 million of earnings on equity method investees, $62 million of interest expense and $3 million of income tax expense. Such amounts for the three months ended March 31, 2022 were $73 million of earnings on equity method investees, $(91) million of interest expense (benefit) and $35 million of income tax expense. Dominion Energy’s Consolidated Balance Sheets at both March 31, 2023 and December 31, 2022 include $2.7 billion within noncurrent assets held for sale for Dominion Energy’s 50% noncontrolling limited partnership interest in Cove Point.

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 Companies’ Annual Report on Form 10-K for the year ended December 31, 2022.

At March 31, 2023 and December 31, 2022, Dominion Energy has recorded a liability of $100 million and $114 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 $6 million of contributions to Atlantic Coast Pipeline during the three months ended March 31, 2023. Dominion Energy made no contributions to Atlantic Coast Pipeline during the three months ended March 31, 2022.

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

A description of Dominion Energy’s investment in Wrangler (through March 2022) is included in Note 9 to the Consolidated Financial Statements in Dominion Energy’s Annual Report on Form 10-K for the year ended December 31, 2022.

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 three months ended March 31, 2022.

Dominion Privatization

Dominion Energy holds a 50% noncontrolling ownership interest in Dominion Privatization 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, 2022.

In March 2022, Dominion Energy completed its initial contribution of privatization operations in South Carolina (excluding contracts held by DESC), Texas and Pennsylvania to Dominion Privatization for 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 was considered a Level 2 fair value measurement given that it was 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.

Note 11. Property, Plant and Equipment

Acquisitions of Nonregulated Solar Projects

Other than the item discussed below, there have been no significant updates to acquisitions of solar projects by the Companies from those discussed in Note 10 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2022.

In March 2023, Dominion Energy entered into an agreement to acquire the Foxhound solar development project in Virginia (reflected in Contracted Energy) with closing on the agreement expected in 2024. The project is expected to cost approximately $205 million, including the initial acquisition cost, and commence commercial operations in 2024 with a generating capacity of 83 MW. Dominion Energy expects to claim production tax credits on the energy generated and sold by the project. Dominion Energy anticipates that an impairment charge may be required upon closing given its expectation that it is more likely that not that the nonregulated solar generation projects within Contracted Energy will be sold before the end of their useful lives as described in Note 10 to the Consolidated Financial Statements in Dominion Energy’s Annual Report on Form 10-K for the year ended December 31, 2022.

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, 2022.

Virginia Regulation - Key Legislation Affecting Operations

Virginia 2023 Legislation

In April 2023, legislation was enacted that amended several key provisions of the Regulation Act, as previously amended by the GTSA, and revised portions of the existing regulatory framework affecting Virginia Power’s operations. See Note 13 to the

40

Companies’ Annual Report on Form 10-K for the year ended December 31, 2022, for additional information on the Regulation Act and GTSA.

The legislation resets the frequency of base rate reviews from a triennial period, as established under the GTSA, to a biennial period commencing with the 2023 Biennial Review. Such biennial reviews shall include the establishment of an authorized ROE to be utilized for base rates and riders, prospective base rates for the upcoming two-year period based on projected cost of service and a determination by the Virginia Commission as to Virginia Power’s base rate earned return for the most recently completed two-year period against the previously authorized ROE, including any potential credits to customers’ bills.

The legislation provides that the Virginia Commission will establish an authorized ROE of 9.70% for Virginia Power in the 2023 Biennial Review, reflecting the average authorized ROE of vertically integrated electric utilities by the applicable regulatory commissions in the peer group jurisdictions of Florida, Georgia, Texas, Tennessee, West Virginia, Kentucky and North Carolina. Subsequent to the 2023 Biennial Review, all provisions related to this peer group benchmarking expire and the Virginia Commission is authorized to utilize any methodology it deems to be consistent with the public interest to make future ROE determinations. In all future biennial reviews, if the Virginia Commission determines that Virginia Power’s existing base rates will, on a going-forward basis, produce revenues that are either in excess of or below its authorized rate of return, the Virginia Commission is authorized to reduce or increase such base rates, as applicable and necessary, to ensure that Virginia Power’s base rates are just and reasonable while still allowing Virginia Power to recover its costs and earn a fair rate of return. In addition, beginning with the biennial review to be filed in 2025, the Virginia Commission may, at its discretion, increase or decrease Virginia Power’s authorized ROE by up to 50 basis points based on factors that may include reliability, generating plant performance, customer service and operating efficiency, with the provisions applying to such adjustments to be determined in a future proceeding.

The legislation directs that if the Virginia Commission determines as part of the 2023 Biennial Review that Virginia Power has earned more than 70 basis points above its authorized ROE of 9.35% established in the 2021 Triennial Review that 85% of the amount of such earnings above this level be credited to customers’ bills. In future biennial reviews, beginning with the biennial review to be filed in 2025, 85% of any earnings determined by the Virginia Commission to be up to 150 basis points above Virginia Power’s authorized ROE shall be credited to customers’ bills as well as 100% of any earnings that are more than 150 basis points above Virginia Power’s authorized ROE. For the purposes of measuring any bill credits due to customers, associated income taxes are factored into the determination of such amounts. In addition, the legislation eliminates Virginia Power’s ability to utilize Virginia Commission-approved investment amounts in qualifying solar or wind generation facilities or electric distribution grid transformation projects as a CCRO to reduce or offset any earnings otherwise eligible for customer credits as previously permitted under the GTSA.

In addition to the biennial review mechanisms discussed above, the legislation also includes provisions related to other aspects of Virginia Power’s ratemaking framework.

•Riders into base rates: Virginia Power is required to combine certain riders with an aggregate annual revenue requirement of at least $350 million with its base rates effective July 2023. After such riders are combined, they will be considered as part of base rates for the purposes of the biennial review proceedings. The inclusion of such riders cannot serve as the basis for an increase in base rates as part of the 2023 Biennial Review.

•Rider consolidation: Upon determination by the Virginia Commission, certain riders, while remaining separate from base rates, may be consolidated for cost recovery and review purposes.

•Capitalization ratio: The legislation establishes that Virginia Power is required to undertake reasonable efforts to maintain a common equity capitalization to total capitalization ratio through December 2024 of 52.10%.

•Fuel cost securitization: Virginia Power is authorized, on or before July 2024, to petition the Virginia Commission for approval of a financing order for certain deferred fuel costs. Virginia Power is required to permit certain retail customers to opt out of any such deferred fuel cost securitization.

•Electric generation plant retirements: The Virginia Commission shall provide to the Virginia General Assembly, on an annual basis, a report that includes information concerning the reliability impacts of generation unit additions and retirement determinations, along with the potential impact on the purchase of power from generation assets outside of the Virginia jurisdiction, the result of which could impact the depreciable lives of Virginia Power’s electric generation facilities in future periods.

Virginia Regulation - Recent Developments

Virginia Fuel Expenses

In May 2023, 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, 2023 and a projected $1.3 billion under-recovered balance as of June 30, 2023. The projected under-recovered balance includes $578 million representing the remaining two years of under-recovered balance as of June 30, 2022 being collected over a three-year period in accordance with the Virginia Commission’s approval of Virginia Power’s 2022 annual fuel factor as described in Note 13 to the Companies’ Annual Report on Form 10-K for the year ended December 31, 2022. Virginia Power proposed two alternatives to recover these under-collected fuel costs. The first option

41

reflects recovery of the total $3.3 billion fuel cost requirement over the July 2023 through June 2024 fuel period and results in an increase in Virginia Power’s fuel revenues of $631 million when applied to projected kilowatt-hour sales for the period. The second option proposed by Virginia Power incorporates its anticipated July 2023 application to the Virginia Commission for approval of a financing order to securitize up to the projected $1.3 billion under-recovered balance as of June 30, 2023 as permitted under legislation enacted in Virginia in April 2023. Under this option, Virginia Power proposed implementation of the current period fuel factor rate only effective July 2023 on an interim basis, while suspending implementation of the prior-period fuel factor rate pending the Virginia Commission’s consideration of the securitization petition. If approved by the Virginia Commission, the securitization option results in a net decrease in Virginia Power’s fuel revenues for the rate year of approximately $541 million. In addition, Virginia Power has proposed to alter the order in which revenue from certain customers who elect to pay market-based rates would be allocated between base rates and fuel, which if approved would result in a reduction to fuel revenue of $13 million. This matter is pending.

GTSA Filing

In March 2023, Virginia Power filed a petition with the Virginia Commission for approval of Phase III, covering 2024 through 2026, of its plan for electric distribution grid transformation projects as authorized by the GTSA. The plan includes 14 projects covering six components (i) AMI; (ii) customer information platform; (iii) grid improvement projects; (iv) physical and cyber security; (v) telecommunications infrastructure and (vi) customer education. For Phase III, the total proposed capital investment is $1.1 billion and the proposed operations and maintenance investment is $71 million. This matter is pending.

Renewable Generation Projects

In October 2022, Virginia Power filed a petition with the Virginia Commission for CPCNs to construct and operate eight utility-scale projects totaling approximately 474 MW of solar generation and 16 MW of energy storage as part of its efforts to meet the renewable 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. In April 2023, 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 W(5)	June 2022	February 2023	April 2023		105	(4)		(16	)

(1)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.

(2)Consists of $510 million for the transmission component of Virginia Power's base rates and $369 million for Rider T1.

(3)Consists of previously approved phases of Rider U.

(4)In May 2023, Virginia Power filed a notification with the Virginia Commission to combine Riders R, S and W, which have an aggregate revenue requirement of $351 million, into base rates effective July 2023 in accordance with legislation enacted in Virginia in April 2023.

(5)In February 2023, the Virginia Commission also approved Virginia Power's requested revenue requirement for the rate year beginning April 2024. However, as Virginia Power provided notification in May 2023 to combine Rider W into base rates as discussed above, Rider W will cease to be separately collected effective July 2023.

North Carolina Regulation

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 February 2023, PSNC submitted a filing with the North Carolina Commission for a $56 million gas cost decrease with rates effective March 2023. The North Carolina Commission approved the filing in March 2023.

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 March 2023, PSNC submitted a filing with the North Carolina Commission for a $23 million decrease relating to the customer usage tracker. The North Carolina Commission approved the filing in March 2023 with rates effective April 2023.

South Carolina Regulation

DSM Programs

DESC has approval for a DSM rider through which it recovers expenditures related to its DSM programs. In January 2023, DESC filed an application with the South Carolina Commission seeking approval to recover $46 million of costs and net lost revenues associated with these programs, along with an incentive to invest in such programs. DESC requested that rates be effective with the first billing cycle of May 2023. In April 2023, the South Carolina Commission approved the request, effective with the first billing cycle of May 2023.

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 February 2023, DESC filed with the South Carolina Commission a proposal to increase the total fuel cost component of retail electric rates. DESC's proposed adjustment is designed to recover DESC's current base fuel costs, including its existing under-collected balance, over the 12-month period beginning with the first billing cycle of May 2023, along with a requested decrease to DESC's variable environmental and avoided capacity cost component. The net effect of the proposal is an annual increase of $176 million. In March 2023, DESC, the South Carolina Office of Regulatory Staff and another party of record filed a stipulation with the South Carolina Commission for approval to reduce the base fuel cost component reflecting a subsequent decrease in current fuel prices, resulting in a net annual increase of $121 million. In April 2023, the South Carolina Commission voted to approve the stipulation, with rates effective May 2023.

Electric Transmission Project

In March 2023, DESC filed an application with the South Carolina Commission requesting approval to construct and operate 19 miles of 230 kV transmission lines, a substation and associated facilities in Jasper County, South Carolina estimated to cost approximately $55 million. This matter is pending.

43

Electric - Other

DESC utilizes a pension costs rider approved by the South Carolina Commission which is designed to allow recovery of projected pension costs, including under-collected balances or net of over-collected balances, as applicable. The rider is typically reviewed for adjustment every 12 months with any resulting increase or decrease going into effect beginning with the first billing cycle in May. In February 2023, DESC requested that the South Carolina Commission approve an adjustment to this rider to increase annual revenue by $24 million. In April 2023, the South Carolina Commission approved the request.

Natural Gas Base Rate Case

In March 2023, DESC filed its natural gas base rate case and schedules with the South Carolina Commission. DESC proposed a non-fuel, base rate increase of $19 million effective October 2023. The base rate increase was proposed to recover significant investment in distribution infrastructure for the benefit of customers. The proposed rates would provide for an ROE of 10.38% compared to the currently authorized ROE of 10.25%. In addition, DESC elected to continue applicability of the Natural Gas Rate Stabilization Act, which allows for the adjustment of natural gas base rates annually, to its future rates and charges. This matter is pending.

Ohio Regulation

PIR Program

In 2008, East Ohio began PIR, aimed at replacing approximately 25% of its pipeline system. The Ohio Commission has approved East Ohio’s PIR program for capital investments through 2026 with 3% increases of annual capital expenditures per year.

In February 2023, East Ohio filed an application with the Ohio Commission requesting approval to adjust the PIR recovery. The filing reflects gross plant investment for 2022 of $225 million, cumulative gross plant investment of $2.4 billion and a revenue requirement of $305 million. In April 2023, the Ohio Commission approved the request.

CEP Program

In 2011, East Ohio began CEP which enables East Ohio to defer depreciation expense, property tax expense and carrying costs at the debt rate of 6.5% on capital investments not covered by its PIR program to expand, upgrade or replace its infrastructure and information technology systems as well as investments necessary to comply with the Ohio Commission or other government regulations. 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 March 2023, East Ohio filed an application with the Ohio Commission requesting approval to adjust CEP cost recovery rates for 2022 costs. The filing reflects gross plant investment for 2022 of $195 million, cumulative gross plant investment of $1.3 billion and a revenue requirement of $151 million. This matter is pending.

Utah Regulation

Purchased Gas

In February 2023, Questar Gas filed an application with the Utah Commission seeking approval for a $92 million gas cost increase with rates effective March 2023. Subsequently in February 2023, the Utah Commission approved a $164 million gas cost increase reflecting additional undercollected gas costs incurred in January 2023.

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, 2022.

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 March 31, 2023, 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	$	3,157	$	154	$	2,689

(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 March 31, 2023, the sub-limits for DESC and Questar Gas were $500 million and $250 million, respectively.

In March 2023, FERC granted DESC authority through March 2025 to issue short-term indebtedness (pursuant to Section 204 of the Federal Power Act) in amounts not to exceed $2.2 billion outstanding with maturity dates of one year or less. In addition, in March 2023, FERC granted GENCO authority through March 2025 to issue short-term indebtedness not to exceed $200 million outstanding with maturity dates of one year or less.

In addition to the credit facility mentioned above and Virginia Power's letter of credit facilities mentioned below, Dominion Energy also has a credit facility which allows Dominion Energy to issue up to approximately $30 million in letters of credit and will mature in June 2024. At both March 31, 2023 and December 31, 2022, Dominion Energy had $25 million in letters of credit outstanding under this facility.

In March 2023, Dominion Energy entered into an agreement with a financial institution which it expects to allow it to issue up to $100 million in letters of credit. At March 31, 2023, no letters of credit were issued and outstanding associated with this agreement. In April 2023, Dominion Energy issued $58 million in letters of credit associated with this agreement.

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 InvestmentSM as disclosed in Note 17 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2022. At March 31, 2023 and December 31, 2022, Dominion Energy’s Consolidated Balance Sheets include $389 million and $347 million, respectively, with respect to such notes presented within short-term debt. The proceeds are used for general corporate purposes and to repay debt.

In January 2023, Dominion Energy entered into a $2.5 billion 364-day term loan facility which bears interest at a variable rate and will mature in January 2024 with the proceeds to be used to repay existing long-term debt and short-term debt upon maturity and for other general corporate purposes. Concurrently, Dominion Energy borrowed an initial $1.0 billion with the proceeds used to repay

45

long-term debt. In February and March 2023, Dominion Energy borrowed $500 million and $1.0 billion, respectively, with the proceeds used for general corporate purposes and to repay long-term debt. The maximum allowed total debt to total capital ratio under the facility is consistent with such allowed ratio under Dominion Energy’s joint revolving credit facility.

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 March 31, 2023, 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	$	1,010	$	90

(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 March 31, 2023, 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.

In January 2023, Virginia Power entered into a letter of credit facility which allows Virginia Power to issue up to $125 million in letters of credit and matures in January 2026. At March 31, 2023, less than $1 million in letters of credit were issued and outstanding under this facility with no amounts drawn under the letters of credit.

In March 2023, Virginia Power entered into an agreement with a financial institution which it expects to allow it to issue up to $125 million in letters of credit. At March 31, 2023, no letters of credit were issued and outstanding associated with this agreement. In April 2023, Virginia Power issued $80 million in letters of credit associated with this agreement.

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 March 2023, Dominion Energy borrowed $450 million under its Sustainability Revolving Credit Agreement, which, as described in Note 18 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2022, matures in 2024 and bears interest at a variable rate. The proceeds from these borrowings were used for general corporate purposes. At March 31, 2023 and December 31, 2022, Dominion Energy’s Consolidated Balance Sheets include $900 million and $450 million, respectively, with respect to this facility. In April 2023, Dominion Energy repaid $450 million borrowed for general corporate purposes.

In March 2023, Virginia Power issued $750 million of 5.00% senior notes and $750 million of 5.45% senior notes that mature in 2033 and 2053, respectively.

Derivative Restructuring

In August 2020, Virginia Power amended a portfolio of interest rate swaps with a notional value of $900 million, 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, 2022. In March 2023, Virginia Power settled the remaining outstanding interest rate swaps which would have otherwise matured in December 2023, resulting in a $448 million reduction in securities due within one year.

Preferred Stock

Dominion Energy is authorized to issue up to 20 million shares of preferred stock, which may be designated into separate classes. At March 31, 2023 and December 31, 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.

46

Dominion Energy recorded dividends of $7 million ($4.375 per share) for the three months ended March 31, 2022, on the Series A Preferred Stock. Dominion Energy recorded dividends of $9 million ($11.625 per share) for both the three months ended March 31, 2023 and 2022 on the Series B Preferred Stock. Dominion Energy recorded dividends of $11 million ($10.875 per share) for both the three months ended March 31, 2023 and 2022 on the Series C Preferred Stock.

There have been no significant changes to Dominion Energy’s 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, 2022.

Issuance of Common Stock

Dominion Energy recorded, net of fees and commissions, $43 million from the issuance of 1 million shares of common stock for the three months ended March 31, 2023 and $45 million from the issuance of 1 million shares of common stock for the three months ended March 31, 2022, through various programs including Dominion Energy Direct® and employee savings plans as described in Note 20 to the Consolidated Financial Statements to the Companies’ Annual Report on Form 10-K for the year ended December 31, 2022.

At-the-Market Program

In August 2020, Dominion Energy entered into sales agency agreements to effect sales under an at-the-market program as discussed in Note 20 to the Consolidated Financial Statements in the Companies’ Annual Report Form 10-K for the year ended December 31, 2022. Dominion Energy did not issue any shares or enter into any forward sale agreements under this program during the three months ended March 31, 2023.

Repurchase of Common Stock

In November 2020, the Board of Directors authorized the repurchase of up to $1.0 billion of Dominion Energy’s common stock in addition to the $3.0 billion repurchase program authorized in July 2020 and completed in December 2020 as discussed in Note 20 to the Consolidated Financial Statements in the Companies’ Annual Report Form 10-K for the year ended December 31, 2022.

Dominion Energy did not repurchase any shares of common stock during the three months ended March 31, 2023, except for shares tendered by employees to satisfy tax withholding obligations on vested restricted stock, which do not count against its stock repurchase authorization.

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.

47

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 standards 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. In March 2023, the EPA issued a final rule specifying an interstate federal implementation plan to comply with certain aspects of planning for the 2015 ozone standards which will be applicable 60 days after publication in the Federal Register for certain states, including Virginia. The interstate federal implementation plan imposes tighter NOX emissions limits during the ozone season and includes provisions for the use of allowances to cover such emissions. Until implementation plans for the 2015 ozone standards are fully 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, financial condition and/or 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 CO2 equivalent emissions. 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.

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

48

regulators are to make case-by-case entrainment technology determinations after an examination of five mandatory facility-specific factors, including a social cost-benefit test, and six optional facility-specific factors. The rule governs all electric generating stations with water withdrawals above two MGD, with a heightened entrainment analysis for those facilities over 125 MGD. Dominion Energy and Virginia Power currently have 15 and nine facilities, respectively, that are subject to the final regulations. Dominion Energy is also working with the EPA and state regulatory agencies to assess the applicability of Section 316(b) to eight hydroelectric facilities, including three Virginia Power facilities. The Companies anticipate that they may have to install impingement control technologies at certain of these stations that have once-through cooling systems. The Companies are currently evaluating the need or potential for entrainment controls under the final rule as these decisions will be made on a case-by-case basis after a thorough review of detailed biological, technological, and cost benefit studies. 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. In October 2020, the EPA released the final rule that extends the latest dates for compliance. Individual facilities’ compliance dates will vary based on circumstances and the determination by state regulators and may range from 2021 to 2028. 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 for one site at Virginia Power and expects to commence remediation activities in 2023 depending on receipt of final permits and approvals. At both March 31, 2023 and December 31, 2022, Dominion Energy had $47 million, of which $1 million in both periods is reflected in liabilities held for sale 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.

49

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, 2022. 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 March 31, 2023 and December 31, 2022 include reserves of $88 million and $94 million, respectively, included in other current liabilities, and insurance receivables of $72 million and $68 million, respectively, included within other receivables. These balances at March 31, 2023 and December 31, 2022 include $72 million and $68 million, respectively, of offsetting reserves and insurance receivables related to personal injury or wrongful death cases which are currently pending. During both the three months ended March 31, 2023 and 2022, no charges were included in Dominion Energy’s Consolidated Statements of Income.

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. In June 2022, DESC requested approval from the South Carolina Commission to transfer certain real estate with a total settlement value of $51 million to satisfy its remaining obligation under the settlement agreement. In July 2022, the South Carolina Commission voted to approve the request and issued its final order in August 2022. In September 2022, DESC transferred certain non-utility property with a fair value of $28 million to the SCDOR under the settlement agreement. In December 2022, DESC transferred additional utility property with a fair value of $3 million to the SCDOR. In October 2022, DESC filed for approval to transfer the remaining real estate with FERC which was received in November 2022. In March 2023, DESC transferred utility property with a fair value of $10 million to the SCDOR resulting in a gain of $9 million ($7 million after-tax), recorded in losses (gains) on sales of assets in Dominion Energy’s Consolidated Statements of Income for the three months ended March 31, 2023. The remaining utility property transfer is expected to be completed by early 2024 and result in a gain of approximately $10 million upon completion.

Nuclear Operations

Nuclear Insurance

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, 2022.

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, 2022, 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 March 31, 2023, 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.

50

In addition, at March 31, 2023, 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 March 31, 2023, Dominion Energy had issued the following subsidiary guarantees:

	Maximum Exposure
(millions)
Commodity transactions(1)	$	2,710
Nuclear obligations(2)		245
Solar(3)		214
Other(4)		1,269
Total(5)(6)	$	4,438

(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, 2022.

(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 lease term commenced. At the end of the initial lease term, Dominion Energy can (i) extend the term of the lease for an additional five years, subject to the approval of the participants, at current market terms, (ii) purchase the property for an amount equal to the project costs or, (iii) subject to certain terms and conditions, sell the property on behalf of the lessor to a third party using commercially reasonable efforts to obtain the highest cash purchase price for the property. If the project is sold and the proceeds from the sale are insufficient to repay the investors for the project costs, Dominion Energy may be required to make a payment to the lessor, up to 87% of project costs, for the difference between the project costs and sale proceeds. At March 31, 2023, no amounts have been recorded related to this guarantee.

Additionally, at March 31, 2023, Dominion Energy had purchased $268 million of surety bonds, including $190 million at Virginia Power and $38 million relates to entities held for sale, and authorized the issuance of letters of credit by financial institutions of $154 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.

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, 2022.

At March 31, 2023, Dominion Energy’s credit exposure totaled $217 million, primarily related to price risk management activities. Of this amount, investment grade counterparties, including those internally rated, represented 89%. No single counterparty, whether investment grade or non-investment grade, exceeded $48 million of exposure. At March 31, 2023, Virginia Power’s exposure related to wholesale customers totaled $34 million. Of this amount, investment grade counterparties, including those internally rated, represented 54%. No single counterparty, whether investment grade or non-investment grade, exceeded $13 million of exposure.

51

Credit-Related Contingent Provisions

Certain of Dominion Energy and Virginia Power's derivative instruments contain credit-related contingent provisions. These provisions require Dominion Energy and Virginia Power 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, Dominion Energy and Virginia Power would have been required to post additional collateral to its counterparties of $106 million and $45 million, respectively, as of March 31, 2023, and $140 million and $28 million, respectively, as of December 31, 2022. 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 collateral of $1 million at March 31, 2023, and both Dominion Energy and Virginia Power had posted $72 million at December 31, 2022, related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. Virginia Power had no such collateral posted at March 31, 2023. In addition, Dominion Energy and Virginia Power had both posted letters of credit as collateral with counterparties covering $6 million and $20 million of fair value of derivative instruments in a liability position at March 31, 2023 and December 31, 2022, respectively. 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 for Dominion Energy and Virginia Power was $107 million and $45 million, respectively, as of March 31, 2023 and $212 million and $99 million, respectively, as of December 31, 2022, which does not include the impact of any offsetting asset positions.

See Note 9 for additional information about derivative instruments.

Note 19. Related-Party Transactions

Dominion Energy’s transactions with equity method investments are described in Note 10. 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. A discussion of Virginia Power's significant related-party transactions follows.

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 March 31, 2023, Virginia Power’s derivative assets and liabilities with affiliates were $5 million and $82 million, respectively. At December 31, 2022, Virginia Power’s derivative assets and liabilities with affiliates were $33 million and $31 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, 2022. At March 31, 2023 and December 31, 2022, 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 $431 million and $422 million, respectively. At March 31, 2023 and December 31, 2022, 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 $534 million and $518 million, respectively.

DES and other affiliates provide accounting, legal, finance and certain administrative and technical services and licenses 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 March 31,	2023		2022
(millions)
Commodity purchases from affiliates	$	214	$	293
Services provided by affiliates(1)		147		130
Services provided to affiliates		4		4

52

(1)Includes capitalized expenditures of $54 million and $39 million for the three months ended March 31, 2023 and 2022, respectively.

Virginia Power has borrowed funds from Dominion Energy under short-term borrowing arrangements. There were $1.2 billion and $2.0 billion in short-term demand note borrowings from Dominion Energy as of March 31, 2023 and December 31, 2022, respectively. Virginia Power had no outstanding borrowings, net of repayments, under the Dominion Energy money pool for its nonregulated subsidiaries as of March 31, 2023 and December 31, 2022. Interest charges related to Virginia Power’s borrowings from Dominion Energy were $24 million and less than $1 million for the three months ended March 31, 2023 and 2022, respectively.

There were no issuances of Virginia Power’s common stock to Dominion Energy for the three months ended March 31, 2023 and 2022.

In January 2023, Virginia Power entered into a lease contract with an affiliated entity for the use of a Jones Act compliant offshore wind installation vessel currently under development with commencement of the 20-month lease term in August 2025 at a total cost of approximately $240 million plus ancillary services.

Note 20. Employee Benefit Plans

Net Periodic Benefit (Credit) Cost

The service cost component of net periodic benefit (credit) cost is reflected in other operations and maintenance expense in Dominion Energy’s Consolidated Statements of Income, except for $4 million and $6 million for the three months ended March 31, 2023 and 2022, respectively, presented in discontinued operations. The non-service cost components of net periodic benefit (credit) cost are reflected in other income (expense) in Dominion Energy’s Consolidated Statements of Income, except for $(11) million and $(11) million for the three months ended March 31, 2023 and 2022, respectively, presented in discontinued operations. The components of Dominion Energy’s provision for net periodic benefit cost (credit) are as follows:
