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, following completion of the GT&S Transaction in November 2020, a noncontrolling interest in Cove Point. See Note 3 for a description of the sale of substantially all of Dominion Energy’s gas transmission and storage operations to BHE through the GT&S Transaction completed in November 2020 and the anticipated sale of Dominion Energy’s remaining regulated gas transmission and storage services in the Rocky Mountain region of the U.S.

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, 2020.

In the Companies’ opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position at June 30, 2021, their results of operations and changes in equity for the three and six months ended June 30, 2021 and 2020 and their cash flows for the six months ended June 30, 2021 and 2020. 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. At June 30, 2021, Dominion Energy owns 50% of the voting interests in Four Brothers and Three Cedars and has a controlling financial interest over the entities through its right to control operations. GIP’s ownership interest in Four Brothers and Three Cedars, Terra Nova Renewable Partners’ 33% interest in certain Dominion Energy nonregulated solar projects and Brookfield’s 25% interest in Cove Point (effective December 2019 until November 2020) are reflected as noncontrolling interest in Dominion Energy’s Consolidated Financial Statements. In August 2021, Dominion Energy entered into an agreement with Terra Nova Renewable Partners to sell its remaining controlling financial interest in certain nonregulated solar projects. See Note 11 for more 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’ 2020 Consolidated Financial Statements and Notes have been reclassified to conform to the 2021 presentation for comparative purposes; however, such reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows. Effective in the second quarter of 2021, the Companies updated their Statements of Cash Flows to present net charges for allowance for credit risk and write-offs of accounts receivables within other adjustments to reconcile net income to net cash provided by operating activities from the previous presentation within changes in accounts receivable.

Property, Plant and Equipment

In March 2020, Virginia Power committed to retire certain coal- and oil-fired generating units before the end of their useful lives based on economic and other factors, including but not limited to market power prices and the VCEA. These units will be retired after they meet their capacity obligations to PJM in 2023. As a result, Virginia Power recorded a charge of $754 million ($561 million after-tax) in the first quarter of 2020, primarily included in impairment of assets and other charges in its Consolidated Statements of Income. This charge is considered a component of Virginia Power’s base rates deemed recovered under the GTSA, subject to review as

23

discussed in Note 13 to the Consolidated Financial Statements in Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2020.

In the second quarter of 2020, Virginia Power recorded charges of $30 million ($22 million after-tax) associated with dismantling certain of these electric generation facilities, recorded in impairment of assets and other charges 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.

Note 3. Acquisitions and Dispositions

Disposition of Gas Transmission & Storage Operations

In July 2020, Dominion Energy entered into an agreement with BHE with a total value of approximately $10 billion, comprised of approximately $4.0 billion of cash consideration (subject to customary closing adjustments) plus the assumption of long-term debt, to sell substantially all of its gas transmission and storage operations, including processing assets, as well as noncontrolling partnership interests in Iroquois, JAX LNG and White River Hub and a controlling interest in Cove Point (consisting of 100% of the general partner interest and 25% of the total limited partner interests). The agreement provides that Dominion Energy retains the assets and obligations of the pension and other postretirement employee benefit plans associated with the operations included in the transaction and relating to services provided through closing. In October 2020, pursuant to a provision in the agreement with BHE, Dominion Energy elected to exclude the Q-Pipe Group from the transaction as approval under the Hart-Scott-Rodino Act had not been obtained by mid-September 2020. Concurrently in October 2020, Dominion Energy and BHE entered into a separate agreement under which Dominion Energy would sell the Q-Pipe Group for cash consideration of $1.3 billion and the assumption of related long-term debt.  In November 2020, Dominion Energy completed the GT&S Transaction 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, 2020.

In connection with closing of the GT&S Transaction, Dominion Energy and BHE entered into a transition services agreement under which Dominion Energy will continue to provide specified administrative services to support the operations of the disposed business for up to 24 months after closing. In addition, BHE will provide certain administrative services to Dominion Energy. Dominion Energy recorded revenue of $6 million and $11 million associated with the transition service agreement in operating revenue in its Consolidated Statements of Income for the three and six months ended June 30, 2021, respectively.

Also in November 2020, BHE provided a $1.3 billion deposit to Dominion Energy on the Q-Pipe Transaction. In July 2021, Dominion Energy and BHE mutually agreed to terminate the Q-Pipe Transaction as a result of ongoing uncertainty associated with receiving approval under the Hart-Scott-Rodino Act. Dominion Energy simultaneously announced its intention to pursue the divestiture of the Q-Pipe Group to an alternative buyer via competitive sales process with targeted closing, subject to applicable regulatory approval, by the end of 2021. Also in July 2021, Dominion Energy entered into an approximately $1.3 billion term loan credit agreement and borrowed the full amount available thereunder.  The agreement matures in December 2021, which can be extended at Dominion Energy’s option to June 2022, and bears interest at a variable rate. The proceeds were utilized to repay the deposit received from BHE on the Q-Pipe Transaction.  Upon completion of a sale of the Q-Pipe Group, Dominion Energy is required to utilize the net proceeds to repay any outstanding balances under the term loan agreement.  The operations of the Q-Pipe Group continue to meet the classification as held-for-sale based on Dominion Energy’s plan to complete a sale of the entities.

The operations included in both the GT&S Transaction and the Q-Pipe Group are presented in held-for-sale and discontinued operations effective July 2020. As a result, the previously reported amounts have been recast to reflect this presentation and depreciation and amortization ceased on the applicable assets. As Cove Point had previously been consolidated within Dominion Energy’s financial statements, balances associated with Cove Point prior to the closing of the GT&S Transaction are presented within held-for-sale and discontinued operations. See Note 10 for further information regarding Dominion Energy’s equity method investment in Cove Point.

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

25

2013. The agreement provides that Dominion Energy retains the assets and obligations of the pension and other postretirement employee benefit plans.  In addition, Dominion Energy may continue to withdraw funds prior to closing from the nuclear decommissioning trust to recover certain spent nuclear fuel and other permitted costs, subject to certain conditions. The sale will be treated as an asset sale for tax purposes and is subject to termination by either party if not completed by December 2022. Closing is contingent on approval from the Wisconsin Commission as well as the NRC for the transfer of control of applicable licenses.  The purchase agreement requires that EnergySolutions be 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 May 2021, Dominion Energy and EnergySolutions submitted a license transfer application to the NRC. Also in May 2021, Dominion Energy submitted an application to the Wisconsin Commission for approval. In July 2021, WPSC and WP&L submitted a joint request to the Wisconsin Commission for the waiver of both of their rights of first refusal to purchase Kewaunee, such rights having been granted as the former owners of Kewaunee. At June 30, 2021, Dominion Energy determined that the assets and liabilities associated with the Kewaunee sale did not meet the criteria to be classified as held for sale due to the significant uncertainty surrounding the timing of or ability to obtain necessary regulatory approvals.

Dominion Energy expects to record a loss if and when it determines that criteria for the classification as held for sale have been met. If such classification had been made at June 30, 2021, Dominion Energy would have recognized a loss of approximately $725 million ($570 million after-tax). If the sale is ultimately completed, the final net loss will primarily depend on the value of the nuclear decommissioning trust and AROs at closing.

Acquisition of Birdseye

In May 2021, Dominion Energy acquired 100% of the ownership interest in Birdseye from BRE Holdings, LLC for total consideration of $46 million, consisting of $28 million in cash and $18 million, measured at fair value at closing, of consideration contingent on the achievement of certain revenue targets and future development project sales. Birdseye is primarily engaged in the development of solar energy projects in southeastern states in the U.S. with 2.5 GW of solar generation projects under development. The allocation of the purchase price resulted in $25 million of development project assets, primarily reflected in other deferred charges and other assets in Dominion Energy’s Consolidated Balance Sheets, and $24 million of goodwill, which is not deductible for tax purposes. The goodwill reflects the value associated with enhancing Dominion Energy's development of regulated and long-term contracted solar generating and electric storage projects. The fair value measurements, including of the assets acquired, were determined using the income approach and are considered Level 3 fair value measurements due to the use of significant judgmental and unobservable inputs, including projected timing and amount of future cash flows. Birdseye is included in Contracted Assets.

At June 30, 2021 and December 31, 2020, Dominion Energy’s contract liability balances were $91 million and $130 million, respectively, and are recorded in other current liabilities and other deferred credits and other liabilities in the Consolidated Balance Sheets.  At June 30, 2021 and December 31, 2020, Virginia Power’s contract liability balances were $43 million and $36 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 six months ended June 30, 2021 and 2020, Dominion Energy recognized revenue of $123 million and $106 million, respectively, from the beginning contract liability balances. During the six months ended June 30, 2021 and 2020, Virginia Power recognized $36 million and $24 million, respectively, from the beginning contract liability balance.  

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
Six Months Ended June 30,	2021			2020			2021			2020
U.S. statutory rate		21.0	%		21.0	%		21.0	%		21.0	%
Increases (reductions) resulting from:
State taxes, net of federal benefit		2.3			4.1			4.5			4.9
Investment tax credits		(5.3	)		(19.5	)		(5.8	)		(11.3	)
Production tax credits		(0.4	)		(1.6	)		(0.6	)		(2.0	)
Reversal of excess deferred income    taxes		(3.5	)		(6.5	)		(2.1	)		(0.8	)
State legislative change		(1.5	)		—			(1.7	)		—
AFUDC - equity		(0.5	)		(2.1	)		(0.6	)		(0.6	)
Other, net		(0.4	)		1.2			0.3			1.1
Effective tax rate		11.7	%		(3.4	)%		15.0	%		12.3	%

For the Companies’ rate-regulated entities, deferred taxes will reverse at the weighted average rate used to originate the deferred tax liability, which in some cases will be 35%. The Companies have recorded an estimate of excess deferred income tax amortization in 2021. The reversal of these excess deferred income taxes will impact the effective tax rate and rates charged to customers. See Note 13 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020 for more information.

As of June 30, 2021, 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, 2020, for a discussion of these unrecognized tax benefits.

The Companies’ 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 (benefit) included in discontinued operations is $11 million and $(562) million for the six months ended June 30, 2021 and 2020, respectively.  2020 income taxes reflect a charge of $81 million for the write-off of tax-related regulatory assets associated with the Atlantic Coast Pipeline Project.

EPS from discontinued operations – Basic		0.03			(2.42	)		0.07			(2.18	)
EPS attributable to Dominion Energy – Basic	$	0.33		$	(1.41	)	$	1.56		$	(1.75	)
EPS from continuing operations – Diluted	$	0.30		$	0.90		$	1.49		$	0.35
EPS from discontinued operations – Diluted		0.03			(2.42	)		0.07			(2.18	)
EPS attributable to Dominion Energy – Diluted	$	0.33		$	(1.52	)	$	1.56		$	(1.83	)

The 2019 Equity Units and the Q-Pipe Transaction deposit, prior to being settled in cash in July 2021, are potentially dilutive securities. See Note 19 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020 and Note 3, respectively, for additional information. The forward stock purchase contracts included within the 2019 Equity Units were excluded from the calculation of diluted EPS from continuing operations for the three and six months ended June 30, 2021 and 2020, 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 will be settled in cash rather than through the issuance of Dominion Energy common stock. For the three and six months ended June 30, 2021, 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 periods. 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 six months ended June 30, 2021 based upon the expectation Dominion Energy would settle in cash rather than through the issuance of Dominion Energy common stock.

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, 2020. See Note 9 in this report for further information about the Companies’ derivatives and hedge accounting activities.

The Companies enter into certain physical and financial forwards, futures, options and swaps, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical and financial forwards, futures and swaps contracts. An option model is used to value Level 3 physical options. The discounted cash flow model for forwards, futures and swaps 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.

34

The following table presents Dominion Energy’s quantitative information about Level 3 fair value measurements at June 30, 2021.  The range and weighted average are presented in dollars for market price inputs and percentages for price volatility.

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

In the second quarter of 2021, Dominion Energy recorded a charge of $20 million ($15 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income to write off substantially all of the long-lived assets of its nonregulated retail software development operations to their estimated fair value, using a market approach, of less than $1 million. The valuation is considered a Level 2 fair value measurement given that it is based on bids received.  

See Note 3 for information on the nonrecurring fair value measurement associated with the acquisition of Birdseye.

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:

	June 30, 2021				December 31, 2020
	Carrying Amount		Estimated Fair Value(1)		Carrying Amount		Estimated Fair Value(1)
(millions)
Dominion Energy
Long-term debt(2)(3)	$	33,076	$	38,558	$	31,996	$	38,773
Supplemental credit facility borrowings(4)		250		250		225		225
Junior subordinated notes(5)		2,862		3,024		3,411		3,633
Virginia Power
Long-term debt(5)	$	13,210	$	15,668	$	13,207	$	16,455

(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 both June 30, 2021 and December 31, 2020, the carrying amount includes the valuation of certain fair value hedges associated with fixed rate debt of $3 million.

(3) Includes amounts classified as held for sale, see Note 3.

(4) Also includes Supplemental 364-Day credit facility borrowings.

(5) Carrying amount includes current portions included in securities due within one year and amounts which represent the unamortized debt issuance costs, discount or premium.

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, 2020. See Note 8 in this report for further information about fair value measurements and associated valuation methods for derivatives.

Derivative assets and liabilities are presented gross on the Companies’ Consolidated Balance Sheets. 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 securities, none of which are subject to restrictions. Cash collateral, as presented in the table below, is used to offset derivative assets and liabilities.  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 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 further information regarding credit-related contingent features for the Companies’ derivative instruments.

The following table presents selected information related to losses on cash flow hedges included in AOCI in Dominion Energy’s Consolidated Balance Sheet at June 30, 2021:

	AOCI After-Tax			Amounts Expected to be Reclassified to Earnings During the Next 12 Months After-Tax			Maximum Term
(millions)
Interest rate	$	(371	)	$	(43	)	390 months
Total	$	(371	)	$	(43	)

The amounts that will be reclassified from AOCI to earnings will generally be offset by the recognition of the hedged transactions (e.g., interest rate payments) in earnings, thereby achieving the realization of prices contemplated by the underlying risk management strategies and will vary from the expected amounts presented above as a result of changes in interest rates.

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 six months ended June 30, 2021 and 2020.

The following table presents the amounts recorded on the balance sheet related to cumulative basis adjustments for fair value hedges:

	Carrying Amount of the Hedged Asset (Liability)(1)						Cumulative Amount of Fair Value Hedging Adjustments Included in the Carrying Amount of the Hedged Assets (Liabilities)(2)

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, 2020.

Income before income taxes recorded by Cove Point was $136 million and $131 million for the three months ended June 30, 2021 and 2020, respectively, and $274 million and $264 million for the six months ended June 30, 2021 and 2020, respectively. For the periods prior to closing of the GT&S Transaction, earnings attributable to Dominion Energy are presented in discontinued operations and subsequent to the closing, earnings attributable to Dominion Energy are presented within earnings from equity method investees in its Consolidated Statements of Income.

Dominion Energy recorded distributions from Cove Point of $77 million and $150 million for the three and six months ended June 30, 2021, respectively.  No contributions were made to Cove Point for the three and six months ended June 30, 2021.

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, 2020.

At June 30, 2021 and December 31, 2020, Dominion Energy has recorded a liability of $115 million and $1.1 billion, respectively, 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 credit facility, through February 2021, and AROs.

In February 2021, Atlantic Coast Pipeline repaid the outstanding borrowed amounts and terminated its revolving credit facility. As of December 31, 2020, Atlantic Coast Pipeline had borrowed $1.8 billion against the revolving credit facility.  Concurrently, Dominion Energy’s related guarantee agreement to support its portion of Atlantic Coast Pipeline’s borrowings was also terminated. Dominion Energy’s Consolidated Balance Sheets included a liability of $6 million associated with this guarantee agreement at December 31, 2020.

Dominion Energy recorded contributions of $13 million during the three months ended June 30, 2020, and $965 million and $29 million during the six months ended June 30, 2021 and 2020, respectively, to Atlantic Coast Pipeline. Dominion Energy recorded no contributions during the three months ended June 30, 2021 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.

DETI provided services to Atlantic Coast Pipeline which totaled $17 million and $37 million for the three and six months ended June 30, 2020, respectively, included in discontinued operations in Dominion Energy’s Consolidated Statements of Income.

Wrangler

A description of Dominion Energy’s investment in Wrangler 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, 2020.  At June 30, 2021 and December 31, 2020, $60 million and $63 million of assets and $17 million and $15 million of liabilities, respectively, associated with the remaining nonregulated retail energy marketing operations expected to be contributed to Wrangler by December 2021 were classified as held for sale and were included in current assets held for sale and current liabilities held for sale on Dominion Energy’s Consolidated Balance Sheets. The related disposal group is primarily comprised of customer receivables, goodwill, inventories and accounts payable.

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, 2020.

Virginia Regulation

2021 Triennial Review

In March 2021, Virginia Power filed its base rate case and accompanying schedules in support of the 2021 Triennial Review. In its filing, Virginia Power did not request an increase in base rates for generation and distribution services and proposed that base rates remain at their existing level. Virginia Power’s earnings test analysis, as filed, demonstrates it earned a combined ROE of 10.85% on its generation and distribution services for the test period, before accounting for forgiven customer balances. Pursuant to Virginia legislation, forgiven customer balances are excluded from the cost of service in determining test period revenues as part of the 2021 Triennial Review. To the extent that the Virginia Commission determines total earnings for the test period to be above Virginia Power’s authorized earnings band, the forgiven balance amounts are offset against the available revenues in the determination of any customer bill credits, or utilization of a CCRO. Test period earnings may be further reduced by Virginia Commission approved investment amounts in qualifying solar or wind generation facilities or electric distribution grid transformation projects that Virginia Power elects to include as a CCRO under the GTSA. In its filing, Virginia Power has elected to utilize $26 million of the Coastal Virginia Offshore Wind Pilot project investment as a CCRO to offset available revenues. The Virginia Commission will determine whether Virginia Power’s earnings for the test period, considered as a whole, were within 70 basis points above or below the authorized ROE of 9.2%. Should the Virginia Commission determine that there are additional available revenues for earnings sharing, then Virginia Power has contingently elected to offset those revenues with additional Virginia Commission approved qualifying CCRO investments. The Virginia Commission will also authorize an ROE for Virginia Power that will be applied to Virginia Power’s riders prospectively and that will also be utilized to measure base rate earnings as of January 1, 2021. Virginia Power is requesting authorization of an ROE of 10.8% based on Virginia Power’s current cost of equity. Pursuant to the Regulation Act, Virginia Power’s authorized ROE shall not be set lower than the average of either (i) the returns reported for the three previous years by not less than a majority of comparable utilities in the Southeastern U.S., with certain limitations as described in the Regulation Act, or (ii) the authorized returns that are set by the applicable regulatory commissions for the same select peer group. In May 2021, Virginia Power filed supplemental testimony to reflect updated test period earnings, including an earned ROE of 10.42%, before accounting for forgiven customer balances, and that no amount of eligible CCRO is necessary to be elected to be utilized. This matter is pending.

In the third and fourth quarters of 2020, Virginia Power recorded a net charge of $130 million related to the use of a CCRO in accordance with the GTSA.  In the first quarter of 2021, Virginia Power recorded a benefit of $130 million ($97 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income to adjust its reserve related to the use of a CCRO in accordance with the GTSA. These amounts reflect the impact related to jurisdictional customers as a result of the 2021 Triennial Review as well as the impact on certain non-jurisdictional customers which follow Virginia Power’s jurisdictional customer rate methodology.

Utility Disconnection Moratorium Legislation

In November 2020, legislation was enacted in Virginia relating to the moratorium on utility disconnections during the COVID-19 pandemic and resulted in Virginia Power forgiving Virginia jurisdictional retail electric customer balances that were more than 30 days past due as of September 30, 2020. As a result, Virginia Power recorded a charge of $127 million in the fourth quarter of 2020.  

56

In connection with the Virginia 2021 budget process, in the first quarter of 2021 Virginia Power recorded a charge of $76 million ($56 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income for Virginia jurisdictional retail electric customer balances that were more than 30 days past due as of December 31, 2020 that Virginia Power is required to forgive.  These forgiven customer balances are factored into Virginia Power’s 2021 Triennial Review as discussed above.

Grid Transformation and Security Act of 2018

In June 2021, Virginia Power filed a petition with the Virginia Commission for approval of a plan for electric distribution grid transformation projects as authorized by the GTSA.  The plan includes 14 projects covering six components: (i) smart meters; (ii) customer information platform; (iii) grid improvement projects; (iv) physical and cyber security; (v) telecommunications infrastructure and (vi) customer education (Phase II). For Phase II, the total proposed capital investment during 2022 – 2023 is $669 million and the proposed operations and maintenance investment is $110 million.  This matter is pending.

Virginia Fuel Expenses

In May 2021, Virginia Power filed its annual fuel factor with the Virginia Commission to recover an estimated $1.4 billion in Virginia jurisdictional projected fuel expenses for the rate year beginning July 1, 2021 and $72 million of estimated net under-recovered balances through June 30, 2021.  In June 2021, the Virginia Commission approved the annual fuel factor.

Solar Facility Projects

In May 2020 and July 2020, Virginia Power entered into and closed on separate agreements to acquire Grassfield Solar, Norge Solar and Sycamore Solar. The projects are expected to cost approximately $170 million in aggregate once constructed, including the initial acquisition cost. The facilities are expected to generate 82 MW combined and be placed into service in 2022. In October 2020, Virginia Power filed an application with the Virginia Commission for CPCNs to construct and operate these projects as part of its efforts to meet the renewable generation development requirements under the VCEA.  In April 2021, the Virginia Commission approved the application.

Riders

Below is a discussion of significant riders associated with various Virginia Power projects:

• The Virginia Commission previously approved Rider U in conjunction with cost recovery to move certain electric distribution facilities underground as authorized by Virginia legislation. In June 2020, Virginia Power proposed an $80 million total revenue requirement consisting of $44 million for previously approved phases and $36 million for phase five costs for Rider U for the rate year beginning April 1, 2021. This total revenue requirement represents a $28 million increase over the previous year. In February 2021, the Virginia Commission approved the filing.

In June 2021, Virginia Power proposed a $96 million total revenue requirement consisting of $61 million for previously approved phases and $35 million for phase six costs for Rider U for the rate year beginning April 1, 2022. This total revenue requirement represents a $16 million increase over the previous year. This matter is pending.

• Pursuant to Virginia legislation, Virginia Power can recover the costs related to the closure of CCR units.  In February 2021, Virginia Power filed for approval of Rider CCR with a proposed $216 million revenue requirement for the rate year beginning December 1, 2021.  This matter is pending.

• In October 2020, Virginia Power applied for approval of Rider CE associated with Grassfield Solar, Norge Solar and Sycamore Solar described above.  In April 2021, the Virginia Commission approved a $10 million revenue requirement for the rate year beginning June 1, 2021.

• The Virginia Commission previously approved Rider T1 concerning transmission rates. In May 2021, Virginia Power proposed a $874 million total revenue requirement consisting of $493 million for the transmission component of Virginia Power’s base rates and $381 million for Rider T1 for the rate year beginning September 1, 2021. This total revenue requirement represents a $190 million decrease versus the revenues to be produced during the rate year under current rates.  This matter is pending.

• Pursuant to the VCEA, Virginia Power can recover costs of compliance with the mandatory renewable portfolio standard program. In December 2020, Virginia Power filed for approval of Rider RPS with a proposed $13 million revenue requirement for the rate year beginning August 1, 2021. In July 2021, the Virginia Commission approved the filing.

• The Virginia Commission previously approved Rider GV relating to Greensville County.  In June 2021, Virginia Power proposed a biennial update procedure for Rider GV with two consecutive rate years. The filing proposed a revenue requirement of $142 million for the rate year beginning April 1, 2022 and a revenue requirement of $127 million for the rate year beginning April 2023.  This matter is pending.

• The Virginia Commission previously approved Rider R relating to Bear Garden. In June 2021, Virginia Power proposed a biennial update procedure for Rider R with two consecutive rate years. The filing proposed a revenue requirement of $59

57

million for the rate year beginning April 1, 2022 and a revenue requirement of $55 million for the rate year beginning April 1, 2023.  This matter is pending.

• The Virginia Commission previously approved Rider S relating to Virginia City Hybrid Energy Center. In June 2021, Virginia Power proposed a biennial update procedure for Rider S with two consecutive rate years. The filing proposed a revenue requirement of $192 million for the rate year beginning April 1, 2022 and a revenue requirement of $191 million for the rate year beginning April 1, 2023.  This matter is pending.

• Pursuant to Virginia legislation, Virginia Power can recover costs associated with participating in a market-based carbon trading program consistent with RGGI.  In August 2021, the Virginia Commission approved Rider RGGI with a $168 million revenue requirement for the rate year beginning September 1, 2021.

North Carolina Regulation

PSNC Base Rate Case

In April 2021, PSNC filed its general rate case application, direct testimony, exhibits, and schedules with the North Carolina Commission.  PSNC proposed a non-fuel, base rate increase of $53 million to be effective November 1, 2021. After considering the benefits of the 2017 Tax Reform Act, the net revenue increase to customers would be approximately $42 million.  The base rate increase was proposed to recover the significant investment in infrastructure to serve a growing customer base, improve safety and reliability of the transmission and distribution system and enhance energy efficiency and sustainability.  The proposed rates would provide for an ROE of 10.25% compared to the currently authorized ROE of 9.7%.  This matter is pending.

South Carolina Regulation

South Carolina Electric Base Rate Case

In August 2020, DESC filed its retail electric base rate case and schedules with the South Carolina Commission. DESC proposed a non-fuel, base rate increase of $178 million, or 7.75%, based on an adjusted test year data, effective on or after the first billing cycle of

58

March 2021. The base rate increase was proposed to recover the significant investment in assets and operating resources required to serve an expanding customer base, maintain the safety, reliability and efficiency of DESC’s system and meet increasingly stringent reliability, security and environmental requirements for the benefit of South Carolina customers.  DESC presented an earned ROE of 5.90% based upon a fully-adjusted test period. The proposed rates would provide for an earned ROE equal to the current authorized earned ROE of 10.25% established in the previous rate case in 2012. In January 2021, the South Carolina Commission approved a proposal made by the South Carolina Office of Regulatory Staff, and agreed to by DESC and other intervenors, to stay the base rate case due to the current economic conditions and to allow the parties more time to negotiate a settlement with a final order to be issued no later than August 2021.  

In July 2021, DESC, the South Carolina Office of Regulatory Staff and other parties of record filed a comprehensive settlement agreement with the South Carolina Commission for approval. The comprehensive settlement agreement provides for a non-fuel, base rate increase of $62 million (resulting in a net increase of $36 million after considering an accelerated amortization of certain excess deferred income taxes) commencing with bills issued on September 1, 2021 and an authorized earned ROE of 9.50%. Additionally, DESC has agreed to commit up to $15 million to forgive retail electric customer balances that were more than 60 days past due as of May 31, 2021, and provide $15 million for energy efficiency upgrades and critical health and safety repairs to customer homes. Pursuant to the comprehensive settlement agreement, DESC would not file a retail electric base rate case prior to July 1, 2023, such that new rates would not be effective prior to January 1, 2024, absent unforeseen extraordinary economic or financial conditions that may include changes in corporate tax rates. In July 2021, the South Carolina Commission voted to approve the comprehensive settlement agreement with a final order expected to be issued in August 2021.

In connection with this matter, Dominion Energy recorded charges for both the three and six months ended June 30, 2021, of $249 million ($187 million after-tax) reflected within impairment of assets and other charges, including $237 million of regulatory assets associated with DESC’s purchases of its first mortgage bonds during 2019 that are no longer probable of recovery under the settlement agreement, and $18 million ($14 million after-tax) reflected within other income in its Consolidated Statements of Income.

DSM Programs

DESC has approval for a DSM rider through which it recovers expenditures related to its DSM programs. In January 2021, DESC filed an application with the South Carolina Commission seeking approval to recover $48 million of costs and net lost revenues associated with these programs, along with an incentive to invest in such programs. In April 2021, the South Carolina Commission approved the filing. In connection with the approval of the comprehensive settlement agreement in the South Carolina base rate case discussed above, the net lost revenue component of the DSM rider will be adjusted resulting in a recovery of $43 million commencing with bills issued on September 1, 2021.

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 2021, DESC filed a proposal with the South Carolina Commission to increase the total fuel cost component of retail electric rates. DESC’s proposed adjustment would increase annual base fuel component recoveries by $36 million and is designed to recover DESC’s current base fuel costs, net of the existing over-collected balance, over the 12-month period beginning with the first billing cycle of May 2021. In addition, DESC proposed a decrease to its variable environmental component and an increase to its distributed energy resource component. In April 2021, the South Carolina Commission approved the filing.

Natural Gas Rates

In June 2021, DESC filed with the South Carolina Commission its monitoring report for the 12-month period ended March 31, 2021 with a total revenue requirement of $426 million. This represents a $9 million overall annual increase to its natural gas rates under the terms of the Natural Gas Rate Stabilization Act effective with the first billing cycle of November 2021. This matter is pending.

Ohio Regulation

PIR Program

In 2008, East Ohio began PIR, aimed at replacing approximately 25% of its pipeline system. In April 2021, the Ohio Commission approved East Ohio’s application to adjust the PIR cost recovery rates for 2020 costs. The filing reflects gross plant investment for 2020 of $178 million, cumulative gross plant investment of $2.0 billion and an annual revenue requirement of $243 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 2021, East Ohio filed an application requesting approval to adjust the CEP cost recovery rates for 2019 and 2020 costs.  The filing reflects gross plant investment for 2019 of $137 million, gross plant investment for 2020 of $99 million, cumulative gross plant investment of $957 million and a revenue requirement of $119 million. This matter is pending.

UEX Rider

59

East Ohio has approval for a UEX Rider through which it recovers the bad debt expense of most customers not participating in the PIPP Plus Program. The UEX Rider is adjusted annually to achieve dollar for dollar recovery of East Ohio’s actual write-offs of uncollectible amounts. In May 2021, East Ohio filed an application with the Ohio Commission requesting approval of its UEX Rider to reflect an increased annual revenue requirement of $20 million to provide for an under-recovered accumulated bad debt expense of $7 million as of March 31, 2021, and recovery of net bad debt expense projected to total $13 million for the twelve-month period ending March 2022. In July 2021, the Ohio Commission approved the filing.

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%.

PREP

In May 2021, Hope filed a PREP application with the West Virginia Commission requesting approval to recover PREP costs related to $54 million and $56 million of projected capital investment for 2021 and 2022, respectively. The application also includes a true-up of PREP costs related to the 2020 actual capital investment of $34 million and sets forth $9 million of annual PREP costs to be recovered in proposed rates effective November 1, 2021. This matter is pending.

Utah Regulation

Purchased Gas

In May 2021, the Utah Commission approved Questar Gas’ request for a $43 million gas cost increase with rates effective June 2021.

Note 14. Leases

Other than the items discussed below, there have been no significant changes regarding the Companies’ leases as described in Note 15 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020.

Dominion Energy’s Consolidated Statements of Income include $55 million and $89 million for the three and six months ended June 30, 2021, respectively, and $53 million and $85 million for the three and six months ended June 30, 2020, respectively, of rental revenue included in operating revenue. Dominion Energy’s Consolidated Statements of Income include $31 million and $58 million for the three and six months ended June 30, 2021, respectively, and $27 million and $50 million for the three and six months ended June 30, 2020, respectively, of depreciation expense included in depreciation, depletion and amortization, related to facilities subject to power purchase agreements under which Dominion Energy is the lessor.

Corporate Office Leasing Arrangement

In December 2019, Dominion Energy signed an agreement with a lessor, as amended in May 2020, to construct and lease a new corporate office property in Richmond, Virginia. The lessor provided equity and had obtained financing commitments from debt investors, totaling $465 million, to fund the estimated project costs. In March 2021, Dominion Energy notified the lessor of its intention to terminate the leasing arrangement effective April 2021. As a result, Dominion Energy recorded a charge of $71 million ($53 million after-tax) in the first quarter of 2021, included in impairments of assets and other charges in its Consolidated Statements of Income, primarily for amounts required to be repaid to the lessor.

Note 15. Variable Interest Entities

There have been no significant changes regarding the entities the Companies consider VIEs as described in Note 16 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020.

Dominion Energy

At June 30, 2021 and December 31, 2020, Dominion Energy’s securities due within one year included $35 million and $32 million, respectively, and at June 30, 2021 and December 31, 2020, Dominion Energy’s long-term debt included $228 million and $239 million, respectively, of debt issued by SBL Holdco, a VIE, net of issuance costs, that is nonrecourse to Dominion Energy and is secured by SBL Holdco’s interest in certain merchant solar facilities.

Virginia Power

60

Virginia Power purchased shared services from DES, an affiliated VIE, of $93 million and $86 million for the three months ended June 30, 2021 and 2020, respectively, and $189 million and $179 million for the six months ended June 30, 2021 and 2020, respectively. Virginia Power’s Consolidated Balance Sheets include amounts due to DES of $129 million and $175 million at June 30, 2021 and December 31, 2020, respectively, recorded in payables to affiliates.

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.

Dominion Energy

In June 2021, Dominion Energy amended its $6.0 billion joint revolving credit facility to provide 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. In addition, the amended facility incorporates certain administrative changes with respect to the anticipated transition from LIBOR to an alternative benchmark rate. The key financial covenants are unchanged from the previous facility.

At June 30, 2021, 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	$	2,636	$	99	$	3,265

(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 June 30, 2021, the sub-limits for DESC and Questar Gas were $500 million and $250 million, respectively.

In January 2021, DESC and GENCO applied to FERC for a two-year short-term borrowing authorization. In March 2021, FERC granted DESC authority through March 2023 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 2021, FERC granted GENCO authority through March 2023 to issue short-term indebtedness not to exceed $200 million outstanding with maturity dates of one year or less.

In addition to the credit facilities 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 matures in June 2022. At June 30, 2021 and December 31, 2020, Dominion Energy had $29 million and $30 million in letters of credit outstanding under this agreement, respectively.

In addition to the credit facilities mentioned above, SBL Holdco has $30 million of credit facilities which had an original stated maturity date of December 2017 with automatic one-year renewals through the maturity of the SBL Holdco term loan agreement in 2023. Dominion Solar Projects III, Inc. has $25 million of credit facilities which had an original stated maturity date of May 2018 with automatic one-year renewals through the maturity of the Dominion Solar Projects III, Inc. term loan agreement in 2024. At both June 30, 2021 and December 31, 2020, no amounts were outstanding under either of these facilities.

In March 2020, Dominion Energy entered into a $900 million 364-Day Revolving Credit Agreement that bore interest at a variable rate. At December 31, 2020, $225 million was outstanding under the agreement. In March 2021, the agreement reached maturity and Dominion Energy repaid the outstanding borrowed amount in full.

61

In July 2021, Dominion Energy entered into an approximately $1.3 billion term loan credit agreement following the termination of the Q-Pipe Transaction as discussed in Note 3.

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 Investment^SM 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, 2020. At June 30, 2021 and December 31, 2020, Dominion Energy’s Consolidated Balance Sheets include $392 million and $268 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, as amended in June 2021. The facility can be used for working capital, as support for the combined commercial paper programs of Virginia Power, Dominion Energy, Questar Gas and DESC and for other general corporate purposes.

At June 30, 2021, 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	$	814	$	12

(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 June 30, 2021, 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 March 2021, PSNC issued, through private placement, $150 million of 3.10% senior notes that mature in 2051.

In April 2021, Dominion Energy issued $600 million of 1.45% senior notes and $500 million of 3.30% senior notes that mature in 2026 and 2041, respectively.

In June 2021, Questar Gas entered into an agreement with certain investors to issue through private placement in August 2021, $125 million 2.21% 10-year senior notes and $125 million 3.15% 30-year senior notes.

In June 2021, Dominion Energy entered into a $900 million Sustainability Revolving Credit Agreement. This supplemental credit facility, which matures in June 2024 and bears interest at a variable rate, offers a reduced interest rate margin with respect to borrowed amounts allocated to certain environmental sustainability or social investment initiatives. Proceeds of the supplemental credit facility also may be used for general corporate purposes, but such proceeds are not eligible for a reduced interest rate margin. At June 30, 2021, $250 million was outstanding under the supplemental credit facility. The proceeds from these borrowings were used to support environmental sustainability and social investment initiatives.  The maximum allowed total debt to total capital ratio under this supplemental credit facility is consistent with such allowed ratio under Dominion Energy’s joint revolving credit facility.

In July 2021, DESC redeemed the remaining principal outstanding of $30 million of its 3.22% first mortgage bonds, plus accrued interest. The bonds would have otherwise matured in October 2021.

In July 2021, Dominion Energy redeemed the remaining principal outstanding of $400 million of its 2.0% senior notes, plus accrued interest. The notes would have otherwise matured in August 2021.

Preferred Stock

62

Dominion Energy is authorized to issue up to 20 million shares of preferred stock, which may be designated into separate classes.  At both June 30, 2021 and December 31, 2020, Dominion Energy had issued and outstanding 2.4 million shares of preferred stock, 1.6 million and 0.8 million of which were designated as the Series A Preferred Stock and the Series B Preferred Stock, respectively.  Dominion Energy’s Series A Preferred Stock and Series B Preferred Stock 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, 2020.  

Dominion Energy recorded dividends of $7 million ($4.375 per share) for both the three months ended June 30, 2021 and 2020, and $14 million ($8.750 per share) for both the six months ended June 30, 2021 and 2020, on the Series A Preferred Stock. Dominion Energy also recorded dividends of $9 million ($11.625 per share) for both the three months ended June 30, 2021 and 2020, and $18 million ($23.250 per share) for both the six months ended June 30, 2021 and 2020, on Series B Preferred Stock. The stock purchase contract liability associated with Dominion Energy’s 2019 Equity Units was $87 million and $129 million at June 30, 2021 and December 31, 2020, respectively. Stock purchase contract payments of $42 million and $41 million were made during the six months ended June 30, 2021 and 2020, respectively. In calculating diluted EPS, Dominion Energy applies the treasury stock method to the stock purchase contracts and the if-converted method to the Series A Preferred Stock.  

Issuance of Common Stock

Dominion Energy recorded, net of fees and commissions, $97 million from the issuance of 1 million shares of common stock for the six months ended June 30, 2021 and $148 million from the issuance of 2 million shares of common stock for the six months ended June 30, 2020, 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, 2020.

In July 2021, Dominion Energy issued 1.4 million shares of its common stock, valued at $104 million, to satisfy DESC’s obligation under a settlement agreement for the FILOT litigation discussed in Note 17.

In August 2021, Dominion Energy issued 0.6 million shares of its common stock, valued at $45 million, to satisfy DESC’s obligation for the initial payment under a settlement agreement with the SCDOR discussed in Note 17.

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, 2020. As of June 30, 2021, Dominion Energy has not issued any shares or entered into any forward sale agreements under this program.

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 as discussed in Note 20 to the Consolidated Financial Statements in the Companies’ Annual Report Form 10-K for the year ended December 31, 2020. Dominion Energy did not repurchase any shares of common stock during the six months ended June 30, 2021.

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. 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.

63

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. Until the states have developed implementation plans for the standard, 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. While the EPA has stated its intention to replace the ACE Rule, it is unknown at this time if or how the EPA will issue a replacement for the ACE Rule and how that replacement will affect the Companies’ 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. In January 2021, the EPA published a final rule affirming that fossil fuel-fired electric generating units meet the requirement that a source category “significantly contribute” to endangering air pollution for the purposes of regulating GHG emissions from new, modified and reconstructed stationary sources. The January 2021 rule also established a threshold for the “significant contribution” threshold that would have meant that no other source category, such as oil and gas facilities, petroleum refineries, and boilers, would meet that requirement at this time. In April 2021, the U.S. Court of Appeals for the D.C. Circuit granted an unopposed motion by the EPA to vacate and remand the January 2021 rule. 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.

64

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 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, technology, cost and 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 12 sites associated with Dominion Energy, including certain sites acquired in the SCANA Combination, remediation work has been substantially completed under federal or state oversight. Where required, the sites are following state-approved groundwater monitoring programs. Dominion Energy has proposed remediation plans associated with three sites, including one at Virginia Power, and expects to commence remediation activities in 2021 or 2022 depending on receipt of final permits and approvals. At June 30, 2021 and December 31, 2020, Dominion Energy had $40 million and $42 million, respectively, and Virginia

65

Power had $25 million and $26 million, respectively, of reserves recorded. In addition, for one site associated with Dominion Energy, an updated work plan submitted to SCDHEC in September 2018, would increase costs by approximately $11 million if approved by federal and state agencies. In September 2020, this plan was submitted to the Army Corps of Engineers. 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 to events occurring before closing of the SCANA Combination. 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 June 30, 2021 and December 31, 2020 include reserves of $341 million and $208 million, respectively, included within other current liabilities, and insurance receivables of $56 million and $8 million, respectively, included within other receivables. During the three and six months ended June 30, 2021, Dominion Energy’s Consolidated Statements of Income include charges of $40 million ($30 million after-tax) and $100 million ($75 million after-tax), respectively, included within impairment of assets and other charges. During the six months ended June 30, 2020, Dominion Energy’s Consolidated Statements of Income include charges of $25 million ($25 million after-tax) included within other income (expense).

Ratepayer Class Actions

In May 2018, a consolidated complaint against DESC, SCANA and the State of South Carolina was filed in the State Court of Common Pleas in Hampton County, South Carolina (the DESC Ratepayer Case). The plaintiffs alleged, among other things, that DESC was negligent and unjustly enriched, breached alleged fiduciary and contractual duties and committed fraud and misrepresentation in failing to properly manage the NND Project, and that DESC committed unfair trade practices and violated state anti-trust laws. In December 2018, the State Court of Common Pleas in Hampton County entered an order granting preliminary approval of a class action settlement. The court entered an order granting final approval of the settlement in June 2019, which became effective in July 2019. The settlement agreement, contingent upon the closing of the SCANA Combination, provided that SCANA and DESC establish an escrow account and proceeds from the escrow account would be distributed to the plaintiffs, after payment of certain taxes, attorneys' fees and other expenses and administrative costs. The escrow account would include (1) up to $2.0 billion, net of a credit of up to $2.0 billion in future electric bill relief, which would inure to the benefit of the escrow account in favor of class members over a period of time established by the South Carolina Commission in its order related to matters before the South Carolina Commission related to the NND Project, (2) a cash payment of $115 million and (3) the transfer of certain DESC-owned real estate or sales proceeds from the sale of such properties, which counsel for the plaintiffs estimated to have an aggregate value between $60 million and $85 million. At the closing of the SCANA Combination, SCANA and DESC funded the cash payment portion of the escrow account. In July 2019, DESC transferred $117 million representing the cash payment, plus accrued interest, to the plaintiffs. Through August 2020, property, plant and equipment with a net recorded value of $27 million had been transferred to the plaintiffs in coordination with the court-appointed real estate trustee to satisfy the settlement agreement. In September 2020, the court entered an order approving a final resolution of the transfer of real estate or sales proceeds with a cash contribution of $38.5 million by DESC and the conveyance of property, plant and equipment with a net recorded value of $3 million, which was completed by DESC in October 2020.

In September 2017, a purported class action was filed by Santee Cooper ratepayers against Santee Cooper, DESC, Palmetto Electric Cooperative, Inc. and Central Electric Power Cooperative, Inc. in the State Court of Common Pleas in Hampton County, South Carolina (the Santee Cooper Ratepayer Case). The allegations were substantially similar to those in the DESC Ratepayer Case. In March 2020, the parties executed a settlement agreement relating to this matter as well as the Luquire Case and the Glibowski Case described below. The settlement agreement provided that Dominion Energy and Santee Cooper establish a fund for the benefit of class members in the amount of $520 million, of which Dominion Energy’s portion was $320 million of shares of Dominion Energy common stock. In July 2020, the court issued a final approval of the settlement agreement. In September 2020, Dominion Energy issued $322 million of shares of Dominion Energy common stock to satisfy its obligation under the settlement agreement, including interest charges.

66

In July 2019, a similar purported class action was filed by certain Santee Cooper ratepayers against DESC, SCANA, Dominion Energy and former directors and officers of SCANA in the State Court of Common Pleas in Orangeburg, South Carolina (the Luquire Case). In August 2019, DESC, SCANA and Dominion Energy were voluntarily dismissed from the case. The claims were similar to the Santee Cooper Ratepayer Case. In March 2020, the parties executed a settlement agreement as described above relating to this matter as well as the Santee Cooper Ratepayer Case and the Glibowski Case. This case was dismissed as part of the Santee Cooper Ratepayer Case settlement described above.

RICO Class Action

In January 2018, a purported class action was filed, and subsequently amended, against SCANA, DESC and certain former executive officers in the U.S. District Court for the District of South Carolina (the Glibowski Case). The plaintiff alleged, among other things, that SCANA, DESC and the individual defendants participated in an unlawful racketeering enterprise in violation of RICO and conspired to violate RICO by fraudulently inflating utility bills to generate unlawful proceeds. In March 2020, the parties executed a settlement agreement as described above relating to this matter as well as the Santee Cooper Ratepayer Case and the Luquire Case. This case was dismissed as part of the Santee Cooper Ratepayer Case settlement described above.

SCANA Shareholder Litigation

In September 2017, a purported class action was filed against SCANA and certain former executive officers and directors in the U.S. District Court for the District of South Carolina. Subsequent additional purported class actions were separately filed against all or nearly all of these defendants (collectively the SCANA Securities Class Action). In January 2018, the U.S. District Court for the District of South Carolina consolidated these suits, and the plaintiffs filed a consolidated amended complaint in March 2018. The plaintiffs alleged, among other things, that the defendants violated §10(b) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder, and that the individually named defendants are liable under §20(a) of the same act. In December 2019, the parties executed a settlement agreement pursuant to which SCANA would pay $192.5 million, up to $32.5 million of which could be satisfied through the issuance of shares of Dominion Energy common stock, subject to court approval. In February 2020, the U.S. District Court for the District of South Carolina granted preliminary approval of the settlement agreement, pending a fairness hearing, and granted final approval in July 2020. In March 2020, SCANA funded an escrow account with $160 million in cash and paid the balance of $32.5 million in cash in August 2020 to satisfy the settlement.

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 will be utilized to satisfy a portion of the Federal Court Merger Case and the State Court Merger Case 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

67

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 will be partially satisfied by the State Court Derivative Case settlement described above.

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.

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. This case is pending.

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. This case is pending.

FILOT Litigation and Related Matters

In November 2017, Fairfield County filed a complaint and a motion for temporary injunction against DESC in the State Court of Common Pleas in Fairfield County, South Carolina, making allegations of breach of contract, fraud, negligent misrepresentation, breach of fiduciary duty, breach of implied duty of good faith and fair dealing and unfair trade practices related to DESC’s termination of the FILOT agreement between DESC and Fairfield County related to the NND Project. The plaintiff sought a temporary and permanent injunction to prevent DESC from terminating the FILOT agreement. The plaintiff withdrew the motion for temporary injunction in December 2017. In July 2021, the parties executed a settlement agreement requiring DESC to pay $99 million, which could be satisfied in either cash or shares of Dominion Energy common stock. Also in July 2021, the State Court of Common Pleas in Fairfield County, South Carolina approved the settlement. In July 2021, Dominion Energy issued 1.4 million shares of Dominion Energy common stock to satisfy DESC’s obligation under the settlement agreement.

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 September and October 2017, SCANA was served with subpoenas issued by the U.S. Attorney’s Office for the District of South Carolina and the Staff of the SEC’s Division of Enforcement seeking documents related to the NND Project. In February 2020, the SEC filed a complaint against SCANA, two of its former executive officers and DESC in the U.S. District Court for the District of South Carolina alleging that the defendants violated federal securities laws by making false and misleading statements about the NND Project. In April 2020, SCANA and DESC reached an agreement in principle with the Staff of the SEC’s Division of Enforcement to settle, without admitting or denying the allegations in the complaint. In December 2020, the U.S. District Court for the District of

68

South Carolina issued an order approving the settlement which required SCANA to pay a civil monetary penalty totaling $25 million, and SCANA and DESC to pay disgorgement and prejudgment interest totaling $112.5 million, which disgorgement and prejudgment interest amount were deemed satisfied by the settlements in the SCANA Securities Class Action and the DESC Ratepayer Case. SCANA paid the civil penalty in December 2020. The SEC civil action against two former executive officers of SCANA remains pending and is currently subject to a stay granted by the court in June 2020 at the request of the U.S. Attorney’s Office for the District of South Carolina.

In addition, the South Carolina Law Enforcement Division is conducting a criminal investigation into the handling of the NND Project by SCANA and DESC. Dominion Energy is cooperating fully with the investigations by the U.S. Attorney’s Office and the South Carolina Law Enforcement Division, including responding to additional subpoenas and document requests. Dominion Energy has also entered into a cooperation agreement with the U.S. Attorney’s Office and the South Carolina Attorney General’s Office. The cooperation agreement provides that in consideration of its full cooperation with these investigations to the satisfaction of both agencies, neither such agency will criminally prosecute or bring any civil action against Dominion Energy or any of its current, previous, or future direct or indirect subsidiaries related to the NND Project. A former executive officer of SCANA entered a plea agreement with the U.S. Attorney’s Office and the South Carolina Attorney General’s Office in June 2020 and entered a guilty plea with the U.S. District Court for the District of South Carolina in July 2020. Another former executive officer of SCANA entered a plea agreement with the U.S. Attorney's Office and the South Carolina Attorney General's Office in November 2020 and entered guilty pleas in the U.S. District Court for the District of South Carolina and in South Carolina state court in February 2021. As a result of the pleas, Dominion Energy has terminated indemnity for these former executive officers related to these two cases.

Abandoned NND Project

DESC, for itself and as agent for Santee Cooper, entered into an engineering, construction and procurement contract with Westinghouse and WECTEC in 2008 for the design and construction of the NND Project, of which DESC’s ownership share is 55%. Various difficulties were encountered in connection with the project. The ability of Westinghouse and WECTEC to adhere to established budgets and construction schedules was affected by many variables, including unanticipated difficulties encountered in connection with project engineering and the construction of project components, constrained financial resources of the contractors, regulatory, legal, training and construction processes associated with securing approvals, permits and licenses and necessary amendments to them within projected time frames, the availability of labor and materials at estimated costs and the efficiency of project labor. There were also contractor and supplier performance issues, difficulties in timely meeting critical regulatory requirements, contract disputes, and changes in key contractors or subcontractors. These matters preceded the filing for bankruptcy protection by Westinghouse and WECTEC in March 2017, and were the subject of comprehensive analyses performed by SCANA and Santee Cooper.

Based on the results of SCANA’s analysis, and in light of Santee Cooper's decision to suspend construction on the NND Project, in July 2017, SCANA determined to stop the construction of the units and to pursue recovery of costs incurred in connection with the construction under the abandonment provisions of the Base Load Review Act or through other means. This decision by SCANA became the focus of numerous legislative, regulatory and legal proceedings. Some of these proceedings remain unresolved and are described above.

In September 2017, DESC, for itself and as agent for Santee Cooper, filed with the U.S. Bankruptcy Court for the Southern District of New York Proofs of Claim for unliquidated damages against each of Westinghouse and WECTEC. These Proofs of Claim were based upon the anticipatory repudiation and material breach by Westinghouse and WECTEC of the contract, and assert against Westinghouse and WECTEC any and all claims that are based thereon or that may be related thereto.

Westinghouse’s reorganization plan was confirmed by the U.S. Bankruptcy Court for the Southern District of New York and became effective in August 2018. In connection with the effectiveness of the reorganization plan, the contract associated with the NND Project was deemed rejected. DESC is contesting approximately $285 million of filed liens in Fairfield County, South Carolina. Most of these asserted liens are claims that relate to work performed by Westinghouse subcontractors before the Westinghouse bankruptcy, although some of them are claims arising from work performed after the Westinghouse bankruptcy.

Westinghouse has indicated that some unsecured creditors have sought or may seek amounts beyond what Westinghouse allocated when it submitted its reorganization plan to the U.S. Bankruptcy Court for the Southern District of New York. If any unsecured creditor is successful in its attempt to include its claim as part of the class of general unsecured creditors beyond the amounts in the bankruptcy reorganization plan allocated by Westinghouse, it is possible that the reorganization plan will not provide for payment in full or nearly in full to its pre-petition trade creditors. The shortfall could be significant.

DESC and Santee Cooper were responsible for amounts owed to Westinghouse for valid work performed by Westinghouse subcontractors on the NND Project after the Westinghouse bankruptcy filing until termination of the interim assessment agreement. In

69

December 2019, DESC and Santee Cooper entered into a confidential settlement agreement with W Wind Down Co LLC resolving claims relating to the interim assessment agreement.

Further, some Westinghouse subcontractors who have made claims against Westinghouse in the bankruptcy proceeding also filed against DESC and Santee Cooper in South Carolina state court for damages. Many of these claimants have also asserted construction liens against the NND Project site. DESC also intends to oppose these claims and liens. With respect to claims of Westinghouse subcontractors, DESC believes there were sufficient amounts previously funded during the interim assessment agreement period to pay such validly asserted claims. With respect to the Westinghouse subcontractor claims which relate to other periods, DESC understands that such claims will be paid pursuant to Westinghouse’s confirmed bankruptcy reorganization plan. DESC further understands that the amounts paid under the plan may satisfy such claims in full. Therefore, DESC believes that the Westinghouse subcontractors may be paid substantially (and potentially in full) by Westinghouse. While Dominion Energy cannot be assured that it will not have any exposure on account of unpaid Westinghouse subcontractor claims, which DESC is presently disputing, Dominion Energy believes it is unlikely that it will be required to make payments on account of such claims that would exceed the portion of the Toshiba Settlement allocated for such balances within the SCANA Merger Approval Order recorded in regulatory liabilities on Dominion Energy’s Consolidated Balance Sheets.

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, 2020.

In March 2021, the total liability protection per nuclear incident available to all participants in the Secondary Financial Protection Program decreased from $13.8 billion to $13.7 billion. In June 2021, the total liability protection per nuclear incident available to all participants in the Secondary Financial Protection Program decreased from $13.7 billion to $13.5 billion. These decreases do not impact Dominion Energy’s responsibility per active unit under the Price-Anderson Amendments Act of 1988.

Effective June 2021, Dominion Energy reduced the levels of nuclear property insurance coverage for each of the reactor sites at Millstone, North Anna and Surry from $1.70 billion to the NRC minimum requirement of $1.06 billion. As a result of this reduction in nuclear property insurance coverage, Dominion Energy and Virginia Power’s maximum retrospective premium assessment for the current annual policy period was reduced to $76 million and $35 million, respectively.

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, 2020, 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.

In June 2018, a lawsuit for Kewaunee was filed in the U.S. Court of Federal Claims for recovery of spent nuclear fuel storage costs incurred after 2013. In March 2019, Dominion Energy amended its filing for recovery of spent nuclear fuel storage to include costs incurred for the year ended December 31, 2018. This matter is pending.

Guarantees, Surety Bonds and Letters of Credit

Upon the closing of the GT&S Transaction, Dominion Energy retained its 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 June 30, 2021, Dominion Energy had issued an additional $25 million of guarantees, primarily to support third parties. No amounts related to these guarantees have been recorded.

70

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 June 30, 2021, Dominion Energy had issued the following subsidiary guarantees:

	Maximum Exposure
(millions)
Commodity transactions(1)	$	1,859
Nuclear obligations(2)		202
Solar(3)		463
Other(4)		1,257
Total(5)	$	3,781

(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. Also includes guarantees entered into by DGI on behalf of certain subsidiaries to facilitate the acquisition and 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 guarantees for the new corporate office property and 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, 2020.

Additionally, at June 30, 2021, Dominion Energy had purchased $168 million of surety bonds, including $94 million at Virginia Power, and authorized the issuance of letters of credit by financial institutions of $99 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, 2020.

At June 30, 2021, Dominion Energy’s credit exposure totaled $123 million, primarily related to price risk management activities. Of this amount, investment grade counterparties, including those internally rated, represented 79%. No single counterparty, whether investment grade or non-investment grade, exceeded $38 million of exposure. At June 30, 2021, Virginia Power’s exposure related to wholesale customers totaled $7 million. Of this amount, investment grade counterparties, including those internally rated, represented 60%. No single counterparty, whether investment grade or non-investment grade, exceeded $2 million of exposure.

71

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 June 30, 2021 and December 31, 2020, Dominion Energy would have been required to post $35 million and $14 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 $20 million and $1 million of collateral at June 30, 2021 and December 31, 2020, respectively, related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. 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 $55 million and $15 million at June 30, 2021 and December 31, 2020, respectively, which does not include the impact of any offsetting asset positions.

If the credit-related contingent features underlying these instruments that are in a liability position and not fully collateralized with cash were fully triggered, Virginia Power would not have been required to post any additional collateral to its counterparties at June 30, 2021 and would have been required to post an additional $2 million of collateral to its counterparties at December 31, 2020.

See Note 9 for further information about derivative instruments.

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 June 30, 2021, Virginia Power’s derivative assets and liabilities with affiliates were $26 million and $1 million, respectively. At December 31, 2020, Virginia Power’s derivative assets and liabilities with affiliates were $3 million and $22 million, respectively. See Note 9 for more 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, 2020. At June 30, 2021 and December 31, 2020, 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 $479 million and $436 million, respectively.  At June 30, 2021 and December 31, 2020, 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 $392 million and $354 million, respectively.

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.

The Companies undertake no obligation to update any forward-looking statement to reflect developments occurring after the statement is made.

Accounting Matters

Critical Accounting Policies and Estimates

As of June 30, 2021, there have been no significant changes with regard to the critical accounting policies and estimates disclosed in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020, other than for the addition of the item below. The policies disclosed included the accounting for regulated operations, AROs, income taxes, accounting for derivative contracts and financial instruments at fair value, use of estimates in goodwill impairment testing, use of estimates in long-lived asset and equity method investment impairment testing and employee benefit plans.

Held for sale classification

Dominion Energy recognizes the assets and liabilities of a disposal group as held for sale in the period (i) it has approved and committed to a plan to sell the disposal group, (ii) the disposal group is available for immediate sale in its present condition, (iii) an active program to locate a buyer and other actions required to sell the disposal group have been initiated, (iv) the sale of the disposal group is probable, (v) the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value, and (vi) it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Dominion Energy initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until closing. Upon designation as held for sale, Dominion Energy stops recording depreciation expense and assesses the fair value of the disposal group less any costs to sell at each reporting period and until it is no longer classified as held for sale.

The determination as to whether the sale of the disposal group is probable may include significant judgments from management related to the expectation of obtaining approvals from applicable regulatory agencies such as state utility regulatory commissions, FERC or the U.S. Federal Trade Commission. This analysis is generally based on orders issued by regulatory commissions, past experience and discussions with applicable regulatory authorities and legal counsel.

In May 2021, Dominion Energy entered into an agreement to sell Kewaunee, subject to termination by either party if not completed by December 2022. The consideration as to whether the sale is probable includes judgments related to the ability to obtain the approvals, in a timely manner, of the NRC and the Wisconsin Commission.  Due to the uncertainty surrounding the timing of or ability to obtain approval by the Wisconsin Commission, at June 30, 2021 Dominion Energy did not conclude that the sale is probable and, as a result, the disposal group was not classified as held for sale. Dominion Energy would have recognized a loss of approximately $725 million ($570 million after-tax) if such classification had been met. This loss primarily represents the difference between the nuclear decommissioning trust and AROs at June 30, 2021.  The Wisconsin Commission requires that any excess decommissioning funds be returned to WPSC and WP&L customers following completion of all decommissioning activities. See Note 3 to the Consolidated Financial Statements for additional information.

Results of Operations

Presented below is a summary of Dominion Energy’s consolidated results:

	2021		2020			$ Change
(millions, except EPS)
Second Quarter
Net income (loss) attributable to Dominion Energy	$	285	$	(1,169	)	$	1,454
Diluted EPS		0.33		(1.52	)		1.85
Year-To-Date
Net income (loss) attributable to Dominion Energy	$	1,293	$	(1,439	)	$	2,732
Diluted EPS		1.56		(1.83	)		3.39

Overview

Second Quarter 2021 vs. 2020

Net income attributable to Dominion Energy increased $1.5 billion, primarily due to the absence of charges presented in discontinued operations associated with the cancellation of the Atlantic Coast Pipeline Project and related portions of the Supply Header Project, partially offset by charges associated with the settlement of the South Carolina electric base rate case, a decrease in net investment gains on nuclear decommissioning trust funds and increased unrealized losses on economic hedging activities.

Year-To-Date 2021 vs. 2020

Net income attributable to Dominion Energy increased $2.7 billion, primarily due to the absence of charges presented in discontinued operations associated with the cancellation of the Atlantic Coast Pipeline Project and related portions of the Supply Header Project, the absence of charges related to the planned early retirements of certain electric generation facilities in Virginia and an increase in net investment earnings on nuclear decommissioning trust funds. These increases were partially offset by charges associated with the settlement of the South Carolina electric base rate case.

An analysis of Dominion Energy’s results of operations follows:

Second Quarter 2021 vs. 2020

Operating revenue decreased 2%, primarily reflecting:

• A $147 million decrease due to unfavorable pricing at Millstone, including the economic hedging impacts of net realized and unrealized losses on freestanding derivatives ($138 million);

81

• A $25 million decrease in sales to electric utility customers associated with economic and other usage factors;

• A $22 million decrease from Virginia Power riders; and

• An $18 million decrease in PJM off-system sales.

These decreases were partially offset by:

• A $45 million increase from the absence of planned outages at Millstone;

• A $39 million increase in the fuel cost components included in utility rates as a result of an increase in commodity costs associated with sales to gas utility customers ($27 million) and electric utility customers ($12 million);

• A $28 million increase from gas utility capital cost riders; and

• A $24 million increase in sales to electric utility retail customers, primarily due to an increase in cooling degree days.

Electric fuel and other energy-related purchases decreased 4%, primarily due to a decrease in PJM off-system sales.

Purchased gas increased 34%, primarily due to an increase in commodity costs for gas utilities, which are offset in operating revenue and do not impact net income.

Other operations and maintenance increased 5%, primarily reflecting:

• A $44 million charge related to a revision in estimated recovery of spent nuclear fuel costs associated with the decommissioning of Kewaunee;

• A $33 million increase in outside services;

• A $20 million increase in costs of employer-provided healthcare; and

• A $14 million increase in storm damage and service restoration costs in Virginia Power’s service territory; partially offset by

• The absence of a $22 million charge associated with credit risk on customer accounts related to COVID-19;

• A $18 million decrease in outage costs;

• A $15 million decrease in merger and integration-related costs associated with the SCANA Combination; and

• A $15 million decrease in certain Virginia Power expenditures which are primarily recovered through state- and FERC-regulated rates and do not impact net income.

Impairment of assets and other charges increased $277 million, primarily due to charges associated with the settlement of the South Carolina electric base rate case ($249 million), litigation acquired in the SCANA Combination ($40 million) and the write-off of nonregulated retail software development assets ($20 million), partially offset by the absence of dismantling costs associated with certain Virginia Power electric generation facilities ($30 million).

Earnings from equity method investees increased $63 million, primarily due to an increase in equity method earnings from Cove Point following closing of the GT&S Transaction.

Other income decreased 37%, primarily due to a decrease in net investment gains on nuclear decommissioning trust funds ($200 million) and charges associated with the settlement of the South Carolina electric base rate case ($18 million) partially offset by an increase in non-service components of pension and other postretirement employee benefit plan credits ($28 million).

Interest and related charges increased 30%, primarily due to unrealized losses in 2021 compared to unrealized gains in 2020 associated with freestanding derivatives ($142 million) partially offset by the absence of borrowings in response to COVID-19 in 2020 ($24 million).

Income tax expense decreased $84 million, primarily due to lower pre-tax income ($190 million) and the benefit of a state legislative change ($21 million) partially offset by reduced interim period tax allocation benefits ($140 million).

Net income from discontinued operations including noncontrolling interests increased $2.0 billion, primarily due to a decrease in charges associated with the Atlantic Coast Pipeline Project and related Supply Header Project ($2.1 billion) partially offset by the absence of operations sold in the GT&S Transaction ($81 million).

82

Noncontrolling interests decreased 73%, primarily due to the closing of the GT&S Transaction in November 2020.

Year-To-Date 2021 vs. 2020

Operating revenue decreased 2%, primarily reflecting:

• A $198 million decrease due to unfavorable pricing at Millstone, including the economic hedging impacts of net realized and unrealized losses on freestanding commodity derivatives ($220 million);

• A $151 million decrease from an unbilled revenue reduction at Virginia Power;

• A $62 million decrease in sales to electric utility retail customers associated with economic and other usage factors;

• A $45 million decrease as a result of the contribution of certain nonregulated natural gas retail energy contracts to Wrangler; and

• A $35 million decrease in PJM off-system sales.

These decreases were partially offset by:

• A $109 million increase in sales to electric utility retail customers from an increase in cooling degree days during the cooling season ($24 million) and an increase in heating degree days during the heating season ($85 million);

• A $63 million increase from gas utility capital cost riders;

• A $49 million increase from Virginia Power riders;

• A $34 million increase from the absence of planned outages at Millstone;

• A $33 million net increase in the fuel cost component included in utility rates as a result of an increase in commodity costs associated with sales to gas utility customers ($103 million) partially offset by a decrease in commodity costs associated with sales to electric utility retail customers ($70 million); and

• A $24 million increase in sales to electric utility retail customers associated with growth.

Electric fuel and other energy-related purchases decreased 11%, primarily due to lower commodity costs for electric utilities ($70 million), which are offset in operating revenue and do not impact net income, and a decrease in PJM off-system sales ($35 million).

Purchased electric capacity increased $23 million, primarily due to an increase in expense related to the annual PJM capacity performance market effective June 2020.

Purchased gas increased 15%, primarily due to an increase in commodity costs for gas utilities, which are offset in operating revenue and do not impact net income.

Other operations and maintenance increased 8%, primarily reflecting:

• A $62 million increase in storm damage and restoration costs in Virginia Power’s service territory;

• A $47 million increase in certain Virginia Power expenditures which are primarily recovered through state- and FERC-regulated rates and do not impact net income;

• A $44 million charge related to a revision in estimated recovery of spent nuclear fuel costs associated with the decommissioning of Kewaunee;

• A $33 million increase in costs of employer-provided healthcare; and

• A $32 million increase in outside services; partially offset by

• A $23 million decrease in merger and integration-related costs associated with the SCANA Combination; and

• The absence of a $22 million charge associated with credit risk on customer accounts related to COVID-19.

Impairment of assets and other charges decreased 49%, primarily reflecting:

• The absence of charges associated with the planned early retirements of certain electric generation facilities in Virginia ($750 million);

• A decrease to the CCRO reserve associated with the 2021 Triennial Review ($130 million); and

83

• The absence of dismantling costs associated with certain Virginia Power electric generation facilities ($30 million); partially offset by

• Charges associated with the settlement of the South Carolina electric base rate case ($249 million);

• Charges associated with litigation acquired in the SCANA Combination ($100 million);

• A charge for the forgiveness of Virginia retail electric customer accounts in arrears pursuant to Virginia’s 2021 budget process ($77 million);

• A charge for corporate office lease termination ($71 million); and

• A charge for the write-off of nonregulated retail software development assets ($20 million).

Earnings from equity method investees increased $140 million, primarily due to an increase in equity method earnings from Cove Point following closing of the GT&S Transaction.

Other income increased $558 million, primarily due to net investment gains in 2021 compared to net investment losses in 2020 on nuclear decommissioning trust funds ($471 million), an increase in non-service components of pension and other postretirement employee benefit plan credits ($64 million), the absence of charges associated with litigation acquired in the SCANA Combination ($25 million) and an increase in AFUDC associated with rate-regulated projects ($17 million), partially offset by charges associated with the settlement of the South Carolina electric base rate case ($18 million).

Interest and related charges decreased 31%, primarily due to unrealized gains in 2021 compared to unrealized losses in 2020 associated with freestanding derivatives ($233 million), the absence of charges associated with the early redemption of certain securities in the first quarter of 2020 ($31 million) and the absence of borrowings in response to COVID-19 in 2020 ($24 million).

Income tax expense increased $178 million, primarily due to higher pre-tax income ($214 million) partially offset by the benefit of a state legislative change ($21 million).

Net income from discontinued operations including noncontrolling interests increased $1.8 billion, primarily due to a decrease in charges associated with the Atlantic Coast Pipeline Project and related Supply Header Project ($2.1 billion) partially offset by the absence of operations sold in the GT&S Transaction ($218 million).

Noncontrolling interests decreased 85%, primarily due to the closing of the GT&S Transaction in November 2020.

An analysis of Virginia Power’s results of operations follows:

Second Quarter 2021 vs. 2020

Operating revenue decreased 4%, primarily reflecting:

• A $49 million decrease in sales to electric utility retail customers associated with economic and other usage factors;

• A $22 million decrease from riders; and

• An $18 million decrease in PJM off-system sales; partially offset by

• A $20 million increase in sales to retail customers, primarily due to an increase in cooling degree days.

Electric fuel and other energy-related purchases decreased 5%, primarily due to a decrease in PJM off-system sales.

Purchased electric capacity increased $12 million, primarily due to an increase in expense related to the annual PJM capacity performance market effective June 2020.

Other operations and maintenance increased 6%, primarily reflecting:

• A $15 million increase in outside services;

• A $14 million increase in storm damage and service restoration costs;

• A $14 million increase in planned outage costs; and

• A $14 million increase in salaries, wages and benefits and administrative costs; partially offset by

• A $15 million decrease in certain expenses which are primarily recovered through state- and FERC-regulated rates and do not impact net income; and

• The absence of a $13 million charge associated with credit risk on customer accounts related to COVID-19.

Impairment of assets and other charges decreased 73%, primarily due to the absence of charges for dismantling costs associated with certain electric generation facilities ($30 million).

Other income decreased 23%, primarily due to a decrease in net investment gains on nuclear decommissioning trust funds.

89

Income tax expense increased 15%, primarily due to reduced interim period tax allocation benefits ($45 million) partially offset by lower pre-tax income ($19 million) and the benefit of a state legislative change ($16 million).

Year-To-Date 2021 vs. 2020

Operating revenue decreased 4%, primarily reflecting:

• A $151 million decrease from an unbilled revenue reduction;

• A $77 million decrease in sales to electric utility retail customers associated with economic and other usage factors;

• A $69 million decrease in the fuel cost component included in utility rates as a result of a net decrease in commodity costs associated with sales to electric utility retail customers; and

• A $35 million decrease in PJM off-system sales; partially offset by

• A $88 million increase in sales to retail customers from an increase in cooling degree days during the cooling season ($20 million) and an increase in heating degree days during the heating season ($68 million);

• A $49 million increase from riders; and

• A $24 million increase in sales to electric utility retail customers associated with growth.

Electric fuel and other energy-related purchases decreased 12%, primarily due to lower commodity costs for electric utilities ($69 million), which are offset in operating revenue and do not impact net income, and a decrease in PJM off-system sales ($35 million).

Purchased electric capacity increased $18 million, primarily due to an increase in expense related to the annual PJM capacity performance market effective June 2020.

Other operations and maintenance increased 15%, primarily reflecting:

• A $62 million increase in storm damage and service restoration costs;

• A $47 million increase in certain expenses which are primarily recovered through state- and FERC-regulated rates and do not impact net income;

• A $22 million increase in outside services;

• A $19 million increase in planned outage costs; and

• A $13 million increase in salaries, wages and benefits; partially offset by

• The absence of a $13 million charge associated with credit risk on customer accounts related to COVID-19; and

• A $10 million reduction in bad debt expense due to the forgiveness of Virginia retail electric customer accounts in arrears pursuant to Virginia’s 2021 budget process.

Impairment of assets and other charges decreased $847 million, primarily reflecting:

• The absence of charges associated with the planned early retirements of certain electric generation facilities ($750 million);

• A decrease to the CCRO reserve associated with the 2021 Triennial Review ($130 million); and

• The absence of charges for dismantling costs associated with certain electric generation facilities ($30 million); partially offset by

• A charge for the forgiveness of Virginia retail electric customer accounts in arrears pursuant to Virginia’s 2021 budget process ($77 million).

Other income increased $72 million, primarily due to net investment gains in 2021 compared to net investment losses in 2020 on nuclear decommissioning trust funds ($59 million) and an increase in AFUDC associated with rate-regulated projects ($13 million).

Income tax expense increased $110 million, primarily due to higher pre-tax income ($136 million) partially offset by the benefit of a state legislative change ($16 million).

Liquidity and Capital Resources

Dominion Energy depends on both internal and external sources of liquidity to provide working capital and as a bridge to long-term debt financings. Short-term cash requirements not met by cash provided by operations are generally satisfied with proceeds from short-term borrowings. Long-term cash needs are met through issuances of debt and/or equity securities.

At June 30, 2021, Dominion Energy had $3.3 billion of unused capacity under its joint revolving credit facility.

A summary of Dominion Energy’s cash flows is presented below:

	2021			2020
(millions)
Cash, restricted cash and equivalents at January 1	$	247		$	269
Cash flows provided by (used in):
Operating activities(1)		2,240			3,136
Investing activities(2)		(3,768	)		(3,334	)
Financing activities(3)		1,585			671
Net increase in cash, restricted cash and equivalents		57			473
Cash, restricted cash and equivalents at June 30	$	304		$	742

(1) Includes $108 million and $668 million related to discontinued operations for 2021 and 2020, respectively.

(2) Includes $(980) million and $(369) million related to discontinued operations for 2021 and 2020, respectively.

(3) Includes $(138) million related to discontinued operations for 2020 and no amounts for 2021.

Operating Cash Flows

Net cash provided by Dominion Energy’s operating activities decreased $896 million, including a $560 million decrease from discontinued operations. Net cash provided by continuing operations decreased primarily due to lower deferred fuel cost recoveries and increased margin deposits, partially offset by distributions from Cove Point and a decrease in interest payments.

Dominion Energy believes that its operations provide a stable source of cash flow to contribute to planned levels of capital expenditures and maintain or grow the dividend on common shares.

Dominion Energy’s operations are subject to risks and uncertainties that may negatively impact the timing or amounts of operating cash flows, which are discussed in Part I. Item 1A. Risk Factors in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020.

Credit Risk

Dominion Energy’s exposure to potential concentrations of credit risk results primarily from its energy marketing and price risk management activities. Presented below is a summary of Dominion Energy’s credit exposure as of June 30, 2021 for these activities. Gross credit exposure for each counterparty is calculated prior to the application of collateral and represents outstanding receivables plus any unrealized on- or off-balance sheet exposure, taking into account contractual netting rights.

	Gross Credit Exposure		Credit Collateral		Net Credit Exposure
(millions)
Investment grade(1)	$	78	$	—	$	78
Non-investment grade(2)		4		—		4
No external ratings:
Internally rated—investment grade(3)		22		2		20
Internally rated—non-investment grade(4)		21		—		21
Total(5)	$	125	$	2	$	123

(1) Designations as investment grade are based upon minimum credit ratings assigned by Moody’s Investors Service and Standard & Poor’s. The five largest counterparty exposures, combined, for this category represented approximately 61% of the total net credit exposure.

(2) The five largest counterparty exposures, combined, for this category represented less than 4% of the total net credit exposure.

(3) The five largest counterparty exposures, combined, for this category represented approximately 13% of the total net credit exposure.

91

(4) The five largest counterparty exposures, combined, for this category represented approximately 6% of the total net credit exposure.

(5)   Excludes the Millstone 2019 power purchase agreements.

Investing Cash Flows

Net cash used in Dominion Energy’s investing activities increased $434 million, primarily due to an increase in contributions to equity method affiliates including Atlantic Coast Pipeline, partially offset by a decrease in plant construction and other property additions and the absence of the acquisitions of Pivotal LNG, Inc. and an additional interest in Atlantic Coast Pipeline.

Financing Cash Flows and Liquidity

Dominion Energy relies on capital markets as significant sources of funding for capital requirements not satisfied by cash provided by its operations. As discussed further in Credit Ratings and Debt Covenants in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020, the ability to borrow funds or issue securities and the return demanded by investors are affected by credit ratings. In addition, the raising of external capital is subject to certain regulatory requirements, including registration with the SEC for certain issuances.

Dominion Energy currently meets the definition of a well-known seasoned issuer under SEC rules governing the registration, communication and offering processes under the Securities Act of 1933, as amended. The rules provide for a streamlined shelf registration process to provide registrants with timely access to capital. This allows Dominion Energy to use automatic shelf registration statements to register any offering of securities, other than those for exchange offers or business combination transactions.

Net cash provided by Dominion Energy's financing activities increased $914 million primarily due to lower common stock dividend payments and higher net issuances of debt.

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 Investment^SM. The registration limits the principal amount that may be outstanding at any one time to $1.0 billion. The notes are offered on a continuous basis and bear interest at a floating rate per annum determined by the Dominion Energy Reliability Investment Committee, or its designee, on a weekly basis. The notes have no stated maturity date, are non-transferable and may be redeemed in whole or in part by Dominion Energy or at the investor’s option at any time. At June 30, 2021 and December 31, 2020, Dominion Energy’s Consolidated Balance Sheets include $392 million and $268 million, respectively, with respect to such notes presented within short-term debt.  The proceeds are used for general corporate purposes and to repay debt.

See Note 16 to the Consolidated Financial Statements for further information regarding Dominion Energy’s credit facilities, liquidity and significant financing transactions, including a $900 million Sustainability Revolving Credit Agreement entered into in June 2021 and a $1.3 billion term loan credit agreement entered into in July 2021.

Credit Ratings

Credit ratings are intended to provide banks and capital market participants with a framework for comparing the credit quality of securities and are not a recommendation to buy, sell or hold securities. In the Credit Ratings section of MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020, there is a discussion on the use of capital markets by Dominion Energy as well as the impact of credit ratings on the accessibility and costs of using these markets. As of June 30, 2021, there have been no changes in Dominion Energy’s credit ratings.

Debt Covenants

In the Debt Covenants section of MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020, there is a discussion on the various covenants present in the enabling agreements underlying Dominion Energy’s debt. As of June 30, 2021, there have been no material changes to debt covenants, nor any events of default under Dominion Energy’s debt covenants.

Subsidiary Dividend Restrictions

As of June 30, 2021, there have been no material changes to the subsidiary dividend restrictions disclosed in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020.

92

Future Cash Payments for Contractual Obligations and Planned Capital Expenditures

As of June 30, 2021, there have been no material changes outside the ordinary course of business to Dominion Energy’s contractual obligations nor any material changes to planned capital expenditures as disclosed in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020.

Use of Off-Balance Sheet Arrangements

As of June 30, 2021, there have been no material changes to the off-balance sheet arrangements disclosed in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020, with the exception of the matter disclosed in Use of Off-Balance Sheet Arrangements in MD&A in the Companies’ Quarterly Report on Form 10-Q for the quarter ended March 31, 2021.

Future Issues and Other Matters

The following discussion of future issues and other information includes current developments of previously disclosed matters and new issues arising during the period covered by, and subsequent to, the dates of Dominion Energy’s Consolidated Financial Statements that may impact future results of operations, financial condition and/or cash flows. This section should be read in conjunction with Item 1. Business and Future Issues and Other Matters in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020, Future Issues and Other Matters in MD&A in the Companies’ Quarterly Report on Form 10-Q for the quarter ended March 31, 2021 and Note 17 to the Consolidated Financial Statements in this report.

Environmental Matters

Dominion Energy is 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. See Note 23 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020 and Note 17 to the Consolidated Financial Statements in this report for additional information on various environmental matters.

Legal Matters

See Notes 13 and 23 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020 and Notes 13 and 17 to the Consolidated Financial Statements and Item 1. Legal Proceedings in this report for additional information on various legal matters.

Regulatory Matters

See Notes 3 and 13 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020 and Note 13 to the Consolidated Financial Statements in this report for additional information on various regulatory matters.

Coastal Virginia Offshore Wind Commercial Project

In September 2019, Virginia Power filed applications with PJM for the Coastal Virginia Offshore Wind Commercial project to interconnect 2,640 MW of wind energy off the coast of Virginia adjacent to the Coastal Virginia Offshore Wind Pilot project. The project is expected to be placed in service by the end of 2026 with preliminary cost estimates from late 2019 of approximately $8 billion. Throughout project development, certain planning inputs and assumptions may vary from initial and preliminary estimates. During 2021, inflationary pressure on certain raw materials including steel have been observed which may impact project costs.  In addition, Virginia Power has moved into the detailed design phase for the project’s onshore electric transmission facilities including final route selection with consideration given for resiliency and minimizing environmental impacts. Although total costs for this component cannot be more precisely estimated until a final route is selected, these design factors will likely result in an increase in costs.  While certain cost inputs may increase, further evaluation of turbine design and wind resource in addition to the performance to-date of the Coastal Virginia Offshore Wind Pilot project, is likely to result in a revised assumption of higher lifetime capacity factors which is expected to mitigate potential increases in development costs such that there is no expected change to Virginia Power’s preliminary estimate for the project’s projected levelized cost of energy.  Virginia Power expects to file with the Virginia Commission a request for CPCN and related rider, which filing will include an updated cost estimate for the project, by the end of 2021.

93

Dominion Energy Virginia Solar Projects

Virginia Power has continued to identify projects to meet its renewable generation targets and currently has plans to acquire or construct several solar facilities, including the facilities currently under development, totaling approximately 3.6 GW of expected generating capacity and approximately $7.0 billion of investments.

Dominion Energy Virginia Battery Storage Projects

To support its development of solar generation facilities, Virginia Power plans to acquire or construct multiple battery storage facilities in Virginia, with facilities currently under development totaling approximately 86 MW of storage capacity and approximately $160 million of investment. These facilities are expected to be placed in service in 2022 through 2024.

Gas Distribution Non-Utility Renewable Natural Gas Projects

In August 2021, Dominion Energy announced an expansion of its partnership with Vanguard Renewables, increasing its commitment up to $1 billion.

ITEM 3.

QUANTITATIVE AND QUALITATIVE

DISCLOSURES ABOUT MARKET RISK

The matters discussed in this Item may contain “forward-looking statements” as described in the introductory paragraphs under Part I., Item 2. MD&A in this report. The reader’s attention is directed to those paragraphs for discussion of various risks and uncertainties that may impact the Companies.

Market Risk Sensitive Instruments and Risk Management

The Companies’ financial instruments, commodity contracts and related financial derivative instruments are exposed to potential losses due to adverse changes in commodity prices, interest rates and equity security prices as described below. Commodity price risk is present in the Companies’ electric operations and Dominion Energy’s natural gas procurement and marketing operations due to the exposure to market shifts in prices received and paid for electricity, natural gas and other commodities. The Companies use commodity derivative contracts to manage price risk exposures for these operations. Interest rate risk is generally related to their outstanding debt and future issuances of debt. In addition, the Companies are exposed to investment price risk through various portfolios of equity and debt securities.

The following sensitivity analysis estimates the potential loss of future earnings or fair value from market risk sensitive instruments over a selected time period due to a 10% change in commodity prices or interest rates.

Commodity Price Risk

To manage price risk, the Companies hold commodity-based derivative instruments held for non-trading purposes associated with purchases and sales of electricity, natural gas and other energy-related products.

The derivatives used to manage commodity price risk are executed within established policies and procedures and may include instruments such as futures, forwards, swaps, options and FTRs that are sensitive to changes in the related commodity prices. For sensitivity analysis purposes, the hypothetical change in market prices of commodity-based derivative instruments is determined based on models that consider the market prices of commodities in future periods, the volatility of the market prices in each period, as well as the time value factors of the derivative instruments. Prices and volatility are principally determined based on observable market prices.

A hypothetical 10% decrease in commodity prices would have resulted in a decrease in fair value of $26 million and $2 million of Dominion Energy’s commodity-based derivative instruments as of June 30, 2021 and December 31, 2020, respectively.

A hypothetical 10% decrease in commodity prices would have resulted in a decrease in fair value of $31 million and $35 million of Virginia Power’s commodity-based derivative instruments as of June 30, 2021 and December 31, 2020, respectively.

The impact of a change in energy commodity prices on the Companies' commodity-based derivative instruments at a point in time is not necessarily representative of the results that will be realized when the contracts are ultimately settled. Net losses from commodity-based financial derivative instruments used for hedging purposes, to the extent realized, will generally be offset by recognition of the hedged transaction, such as revenue from physical sales of the commodity.

Interest Rate Risk

The Companies manage their interest rate risk exposure predominantly by maintaining a balance of fixed and variable rate debt. They also enter into interest rate sensitive derivatives, including interest rate swaps and interest rate lock agreements. For variable rate debt outstanding for Dominion Energy and Virginia Power, a hypothetical 10% increase in market interest rates would not have resulted in a material change in earnings at June 30, 2021 or December 31, 2020.  

The Companies also use interest rate derivatives, including forward-starting swaps, interest rate swaps and interest rate block agreements to manage interest rate risk. As of June 30, 2021, Dominion Energy and Virginia Power had $9.2 billion and $2.8 billion, respectively, in aggregate notional amounts of these interest rate derivatives outstanding. A hypothetical 10% decrease in market interest rates would have resulted in a decrease of $160 million and $115 million, respectively, in the fair value of Dominion Energy and Virginia Power interest rate derivatives at June 30, 2021. As of December 31, 2020, Dominion Energy and Virginia Power had $6.9 billion and $2.1 billion, respectively, in aggregate notional amounts of these interest rate derivatives outstanding. A hypothetical 10% decrease in market interest rates would have resulted in a decrease of $124 million and $75 million, respectively, in the fair value of Dominion Energy and Virginia Power’s interest rate derivatives at December 31, 2020.

The impact of a change in interest rates on the Companies’ interest rate-based financial derivative instruments at a point in time is not necessarily representative of the results that will be realized when the contracts are ultimately settled. Net gains and/or losses from

95

interest rate derivative instruments used for hedging purposes, to the extent realized, will generally be offset by recognition of the hedged transaction.

Investment Price Risk

The Companies are subject to investment price risk due to securities held as investments in nuclear decommissioning and rabbi trust funds that are managed by third-party investment managers. These trust funds primarily hold marketable securities that are reported in the Companies’ Consolidated Balance Sheets at fair value.

Dominion Energy recognized net investment gains (including investment income) on nuclear decommissioning and rabbi trust investments of $675 million for the six months ended June 30, 2021, net investment losses (including investment income) on nuclear decommissioning and rabbi trust investments of $207 million for the six months ended June 30, 2020, and net investment gains (including investment income) on nuclear decommissioning and rabbi trust investments of $662 million for the year ended December 31, 2020. Net realized gains and losses include gains and losses from the sale of investments. Dominion Energy recorded in AOCI and regulatory liabilities, a net decrease in unrealized gains on debt investments of $41 million for the six months ended June 30, 2021 and a net increase in unrealized gains on debt investments of $37 million and $57 million for the six months ended June 30, 2020 and the year ended December 31, 2020, respectively.

Virginia Power recognized net investment gains (including investment income) on nuclear decommissioning and rabbi trust investments of $327 million for the six months ended June 30, 2021, net investment losses (including investment income) on nuclear decommissioning and rabbi trust investments of $119 million for the six months ended June 30, 2020, and net investment gains (including investment income) on nuclear decommissioning and rabbi trust investments of $287 million for the year ended December 31, 2020. Net realized gains and losses include gains and losses from the sale of investments. Virginia Power recorded in AOCI and regulatory liabilities, a net decrease in unrealized gains on debt investments of $12 million for the six months ended June 30, 2021 and a net increase in unrealized gains on debt investments of $20 million and $29 million for the six months ended June 30, 2020 and the year ended December 31, 2020, respectively.

Dominion Energy sponsors pension and other postretirement employee benefit plans that hold investments in trusts to fund employee benefit payments. Virginia Power employees participate in these plans. Differences between actual and expected returns on plan assets are accumulated and amortized during future periods. As such, any investment-related declines in these trusts will result in future increases in the net periodic cost recognized for employee benefit plans and will be included in the determination of the amount of cash to be contributed to the employee benefit plans.

ITEM 4. CONTROLS AND PROCEDURES

Senior management of both Dominion Energy and Virginia Power, including Dominion Energy and Virginia Power’s CEO and CFO, evaluated the effectiveness of each company’s disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation process, each of Dominion Energy and Virginia Power’s CEO and CFO have concluded that each company’s disclosure controls and procedures are effective.

There were no changes that occurred during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, Dominion Energy or Virginia Power’s internal control over financial reporting.

96

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Exhibit 4.1

REGISTRATION RIGHTS AGREEMENT

This Registration Rights Agreement (this “Agreement”), dated as of August 6, 2021, is entered into by and between Dominion Energy, Inc., a Virginia corporation (“DEI”), and South Carolina Department of Revenue (the “Department”).

WHEREAS, the Department has agreed to accept on August 6, 2021 a certain number of shares of DEI’s common stock, no par value, as agreed to by the parties (the “DEI Shares”) as partial consideration for the settlement of certain disputed tax liabilities of Dominion Energy South Carolina, Inc., a wholly-owned subsidiary of DEI (“DESC”); and

WHEREAS, as a condition to the Department’s acceptance of the DEI Shares, DEI has agreed to grant certain registration rights to the Department with respect to the DEI Shares on the terms and subject to the conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties and agreements set forth herein, and intending to be legally bound hereby, the parties hereto agree as follows:

1.Definitions

As used in this Agreement, the following capitalized terms shall have the following meanings:

2.Registration Matters

(a)DEI shall prepare and file with the SEC, as soon as reasonably practicable after the transfer of the DEI Shares to the Department, but in no event later than one (1) business day after the transfer of the DEI Shares to the Department, a prospectus supplement under Rule 424(b) (such prospectus supplement or any successor prospectus supplement, the “Resale Prospectus”) to its current Registration Statement on Form S-3 (333-239467) (such registration statement or any successor registration statement, the

“Registration Statement”) to enable the Department to sell the DEI Shares from time to time in any manner contemplated by the Resale Prospectus.  DEI shall thereafter use its commercially reasonable efforts to cause the Registration Statement to remain continuously effective and to prepare and file with the SEC any required amendments or supplements to the Registration Statement or the prospectus contained therein for so long as any of the DEI Shares qualify as Registrable Securities; provided that DEI shall not be required to file any amendment or supplement to the Registration Statement or the prospectus contained therein during the pendency of any “suspension period” provided for in Sections 2(f) and 2(g) below.

(b) DEI shall furnish to the Department or any of its agents copies of the Resale Prospectus and any other documents that the Department or its agents may reasonably request to facilitate the public sale or other disposition of all or any Registrable Securities by the Department.

(c)DEI shall use commercially reasonable efforts to cause the DEI Shares to be listed on the New York Stock Exchange as soon as reasonably practicable after the transfer of the DEI Shares to the Department; but in no event later than the date of the filing of the Resale Prospectus with the SEC.  

(d)DEI or DESC, as applicable, shall bear all expenses relating to the registration and resale of Registrable Securities, including filings fees with SEC, listing fees payable to NYSE, all preapproved brokerage fees and any other fees, including transfer taxes (if any), incurred by the Department relating to the resale of Registrable Securities.  

(e)The Department shall promptly provide any assistance or information reasonably requested by DEI as may be necessary to prepare the Resale Prospectus or otherwise required by DEI to satisfy its obligations under this Agreement to register the resale of Registrable Securities under the Securities Act.

(f)The Department shall not sell or offer to sell, within the meaning of the Securities Act, any Registrable Securities under the Resale Prospectus if DEI notifies the Department in writing of the occurrence of any event or the existence of any state of facts that, in the judgment of DEI’s legal counsel, requires the suspension of any sales under the Resale Prospectus due to pending corporate developments, public filings with the SEC or other similar events.  The right of DEI to suspend the disposition of Registrable Securities under the Resale Prospectus shall not be exercised by DEI for a period longer than is reasonably necessary under the circumstances and, in any event, for more than a total of 90 days in any twelve-month period.  Any such suspension of sales under the Resale Prospectus by the Department shall commence immediately upon receipt of any such notice by the Department and shall last until the Department is notified in writing by DEI that the Department may resume sales under the Resale Prospectus.  

(g) The Department shall also not sell or offer to sell, within the meaning of the Securities Act, any Registrable Securities under the Resale Prospectus if DEI notifies the Department in writing of: (i) any request by the SEC for amendments or supplements to the Registration Statement or the Resale Prospectus; (ii) the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; or (iii) any event or circumstance that necessitates the making of any changes in the Registration Statement or the Resale Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that the Registration Statement and the Resale Prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.  Any such suspension of sales under the Resale Prospectus by the Department shall commence immediately upon receipt of any such notice by the Department and shall last until the Department is notified in writing by DEI that the Department may resume sales under the Resale Prospectus. In the event of any suspension under this Section 2(g), DEI will use its commercially reasonable

2

efforts to cause the use of the Resale Prospectus to be resumed as soon as reasonably possible after delivery of a suspension notice to the Department.

(h)Except as set forth in Sections 2(f) and 2(g) above, the Department may sell Registrable Securities under the Resale Prospectus at any time and from time to time so long as such sales are made in a manner contemplated by the Resale Prospectus, and so long as the Department arranges for delivery of the Resale Prospectus to any transferee receiving such Registrable Securities to the extent required to comply with the prospectus delivery requirements of the Securities Act.

3.Indemnification

(a)DEI hereby agrees to indemnify and hold harmless the Department from and against any and all losses, claims, damages, liabilities or expenses, joint or several (each, a “Loss” and, collectively, “Losses”), to which the Department may become subject under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of DEI, which consent shall not be unreasonably withheld or delayed), to the extent such Losses (or actions in respect thereof as contemplated below) arise out of or are based upon (i) any failure on the part of DEI to comply with any obligation of DEI contained in this Agreement, or (ii) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Resale Prospectus, or any amendment or supplement thereto, or the omission or alleged omission to state in any of them a material fact required to be stated therein or necessary to make the statements in any of them, in light of the circumstances under which they were made, not misleading, and will reimburse the Department for any reasonable legal fees and other reasonable out-of-pocket expenses as such expenses are incurred by the Department in connection with investigating, defending, settling, compromising, or paying any such Loss or action; provided, however, that DEI will not be liable in any such case to the extent that any such Loss arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Resale Prospectus or any amendment or supplement of the Registration Statement or Resale Prospectus in reliance upon and in conformity with information furnished in writing to DEI by the Department, (ii) any untrue statement or omission or alleged untrue statement or omission of a material fact required to make such statement not misleading in the Resale Prospectus that is corrected in any subsequent amendment or supplement thereto that was delivered to the Department before the pertinent sale or sales by the Department, or (iii) any untrue statement or alleged untrue statement or omission or alleged omission in the Registration Statement, the Resale Prospectus, or any amendment or supplement thereto, when used or distributed by the Department during a suspension period under Section 2(f) or 2(g) above.

(b)The Department shall promptly notify DEI of any written notice of the threat or commencement of any action contemplated under Section 3(a) above; provided, however, that the failure to notify DEI will not relieve DEI from any liability which it may have to the Department under Section 3(a) except to the extent DEI is prejudiced as a result of such failure.  DEI will be entitled to participate in, and may elect to assume the defense of, any claim against the Department using counsel reasonably satisfactory to the Department.  If the defendants in any such action include DEI and the Department and the Department reasonably concludes that there may be a conflict between the positions of the Department and DEI in conducting the defense or that there may be a legal defense available to the Department that is different from that available to DEI, the Department will have the right to select separate counsel, with all reasonable fees and expenses of such counsel payable by DEI, to assume such legal defenses and to otherwise participate in the defense. Once the Department receives notice of DEI’s assumption of the defense of any action, DEI will not, except as provided above, be liable to the Department for any legal or other expenses subsequently incurred by the Department in connection with the defense of that claim.  The obligations of DEI and the Department under this Section 3 shall survive the completion of the any sales or other dispositions of Registrable Securities.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Nature of Operations

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, following completion of the GT&S Transaction in November 2020, a noncontrolling interest in Cove Point. See Note 3 for a description of the sale of substantially all of Dominion Energy’s gas transmission and storage operations to BHE through the GT&S Transaction completed in November 2020 and the anticipated sale of Dominion Energy’s remaining regulated gas transmission and storage services in the Rocky Mountain region of the U.S.

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, 2020.

In the Companies’ opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position at June 30, 2021, their results of operations and changes in equity for the three and six months ended June 30, 2021 and 2020 and their cash flows for the six months ended June 30, 2021 and 2020. 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. At June 30, 2021, Dominion Energy owns 50% of the voting interests in Four Brothers and Three Cedars and has a controlling financial interest over the entities through its right to control operations. GIP’s ownership interest in Four Brothers and Three Cedars, Terra Nova Renewable Partners’ 33% interest in certain Dominion Energy nonregulated solar projects and Brookfield’s 25% interest in Cove Point (effective December 2019 until November 2020) are reflected as noncontrolling interest in Dominion Energy’s Consolidated Financial Statements. In August 2021, Dominion Energy entered into an agreement with Terra Nova Renewable Partners to sell its remaining controlling financial interest in certain nonregulated solar projects. See Note 11 for more 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’ 2020 Consolidated Financial Statements and Notes have been reclassified to conform to the 2021 presentation for comparative purposes; however, such reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows. Effective in the second quarter of 2021, the Companies updated their Statements of Cash Flows to present net charges for allowance for credit risk and write-offs of accounts receivables within other adjustments to reconcile net income to net cash provided by operating activities from the previous presentation within changes in accounts receivable. All prior period information has been conformed to this presentation, which does not result in a change to net cash provided by operating activities.

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, 2020, with the exception of the items described below.

Property, Plant and Equipment

In March 2020, Virginia Power committed to retire certain coal- and oil-fired generating units before the end of their useful lives based on economic and other factors, including but not limited to market power prices and the VCEA. These units will be retired after they meet their capacity obligations to PJM in 2023. As a result, Virginia Power recorded a charge of $754 million ($561 million after-tax) in the first quarter of 2020, primarily included in impairment of assets and other charges in its Consolidated Statements of Income. This charge is considered a component of Virginia Power’s base rates deemed recovered under the GTSA, subject to review as

discussed in Note 13 to the Consolidated Financial Statements in Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2020.

In the second quarter of 2020, Virginia Power recorded charges of $30 million ($22 million after-tax) associated with dismantling certain of these electric generation facilities, recorded in impairment of assets and other charges 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 July 2020, Dominion Energy entered into an agreement with BHE with a total value of approximately $10 billion, comprised of approximately $4.0 billion of cash consideration (subject to customary closing adjustments) plus the assumption of long-term debt, to sell substantially all of its gas transmission and storage operations, including processing assets, as well as noncontrolling partnership interests in Iroquois, JAX LNG and White River Hub and a controlling interest in Cove Point (consisting of 100% of the general partner interest and 25% of the total limited partner interests). The agreement provides that Dominion Energy retains the assets and obligations of the pension and other postretirement employee benefit plans associated with the operations included in the transaction and relating to services provided through closing. In October 2020, pursuant to a provision in the agreement with BHE, Dominion Energy elected to exclude the Q-Pipe Group from the transaction as approval under the Hart-Scott-Rodino Act had not been obtained by mid-September 2020. Concurrently in October 2020, Dominion Energy and BHE entered into a separate agreement under which Dominion Energy would sell the Q-Pipe Group for cash consideration of $1.3 billion and the assumption of related long-term debt.  In November 2020, Dominion Energy completed the GT&S Transaction 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, 2020.

In connection with closing of the GT&S Transaction, Dominion Energy and BHE entered into a transition services agreement under which Dominion Energy will continue to provide specified administrative services to support the operations of the disposed business for up to 24 months after closing. In addition, BHE will provide certain administrative services to Dominion Energy. Dominion Energy recorded revenue of $6 million and $11 million associated with the transition service agreement in operating revenue in its Consolidated Statements of Income for the three and six months ended June 30, 2021, respectively.

Also in November 2020, BHE provided a $1.3 billion deposit to Dominion Energy on the Q-Pipe Transaction. In July 2021, Dominion Energy and BHE mutually agreed to terminate the Q-Pipe Transaction as a result of ongoing uncertainty associated with receiving approval under the Hart-Scott-Rodino Act. Dominion Energy simultaneously announced its intention to pursue the divestiture of the Q-Pipe Group to an alternative buyer via competitive sales process with targeted closing, subject to applicable regulatory approval, by the end of 2021. Also in July 2021, Dominion Energy entered into an approximately $1.3 billion term loan credit agreement and borrowed the full amount available thereunder.  The agreement matures in December 2021, which can be extended at Dominion Energy’s option to June 2022, and bears interest at a variable rate. The proceeds were utilized to repay the deposit received from BHE on the Q-Pipe Transaction.  Upon completion of a sale of the Q-Pipe Group, Dominion Energy is required to utilize the net proceeds to repay any outstanding balances under the term loan agreement.  The operations of the Q-Pipe Group continue to meet the classification as held-for-sale based on Dominion Energy’s plan to complete a sale of the entities.

The operations included in both the GT&S Transaction and the Q-Pipe Group are presented in held-for-sale and discontinued operations effective July 2020. As a result, the previously reported amounts have been recast to reflect this presentation and depreciation and amortization ceased on the applicable assets. As Cove Point had previously been consolidated within Dominion Energy’s financial statements, balances associated with Cove Point prior to the closing of the GT&S Transaction are presented within held-for-sale and discontinued operations. See Note 10 for further information regarding Dominion Energy’s equity method investment in Cove Point.

The following table represents selected information regarding the results of operations, which are reported within discontinued operations in Dominion Energy’s Consolidated Statements of Income:

The carrying amounts of major classes of assets and liabilities relating to the disposal groups, which are reported as held for sale in Dominion Energy’s Consolidated Balance Sheets were as follows:

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 agreement provides that Dominion Energy retains the assets and obligations of the pension and other postretirement employee benefit plans.  In addition, Dominion Energy may continue to withdraw funds prior to closing from the nuclear decommissioning trust to recover certain spent nuclear fuel and other permitted costs, subject to certain conditions. The sale will be treated as an asset sale for tax purposes and is subject to termination by either party if not completed by December 2022. Closing is contingent on approval from the Wisconsin Commission as well as the NRC for the transfer of control of applicable licenses.  The purchase agreement requires that EnergySolutions be 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 May 2021, Dominion Energy and EnergySolutions submitted a license transfer application to the NRC. Also in May 2021, Dominion Energy submitted an application to the Wisconsin Commission for approval. In July 2021, WPSC and WP&L submitted a joint request to the Wisconsin Commission for the waiver of both of their rights of first refusal to purchase Kewaunee, such rights having been granted as the former owners of Kewaunee. At June 30, 2021, Dominion Energy determined that the assets and liabilities associated with the Kewaunee sale did not meet the criteria to be classified as held for sale due to the significant uncertainty surrounding the timing of or ability to obtain necessary regulatory approvals.

Dominion Energy expects to record a loss if and when it determines that criteria for the classification as held for sale have been met. If such classification had been made at June 30, 2021, Dominion Energy would have recognized a loss of approximately $725 million ($570 million after-tax). If the sale is ultimately completed, the final net loss will primarily depend on the value of the nuclear decommissioning trust and AROs at closing.

Acquisition of Birdseye

In May 2021, Dominion Energy acquired 100% of the ownership interest in Birdseye from BRE Holdings, LLC for total consideration of $46 million, consisting of $28 million in cash and $18 million, measured at fair value at closing, of consideration contingent on the achievement of certain revenue targets and future development project sales. Birdseye is primarily engaged in the development of solar energy projects in southeastern states in the U.S. with 2.5 GW of solar generation projects under development. The allocation of the purchase price resulted in $25 million of development project assets, primarily reflected in other deferred charges and other assets in Dominion Energy’s Consolidated Balance Sheets, and $24 million of goodwill, which is not deductible for tax purposes. The goodwill reflects the value associated with enhancing Dominion Energy's development of regulated and long-term contracted solar generating and electric storage projects. The fair value measurements, including of the assets acquired, were determined using the income approach and are considered Level 3 fair value measurements due to the use of significant judgmental and unobservable inputs, including projected timing and amount of future cash flows. Birdseye is included in Contracted Assets.

Income Tax Disclosure [Abstract]

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
Six Months Ended June 30,	2021			2020			2021			2020
U.S. statutory rate		21.0	%		21.0	%		21.0	%		21.0	%

State taxes, net of federal benefit		2.3			4.1			4.5			4.9

Production tax credits		(0.4	)		(1.6	)		(0.6	)		(2.0	)
Reversal of excess deferred income    taxes		(3.5	)		(6.5	)		(2.1	)		(0.8	)
State legislative change		(1.5	)		—			(1.7	)		—
AFUDC - equity		(0.5	)		(2.1	)		(0.6	)		(0.6	)
Other, net		(0.4	)		1.2			0.3			1.1
Effective tax rate		11.7	%		(3.4	)%		15.0	%		12.3	%

For the Companies’ rate-regulated entities, deferred taxes will reverse at the weighted average rate used to originate the deferred tax liability, which in some cases will be 35%. The Companies have recorded an estimate of excess deferred income tax amortization in 2021. The reversal of these excess deferred income taxes will impact the effective tax rate and rates charged to customers. See Note 13 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020 for more information.

As of June 30, 2021, 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, 2020, for a discussion of these unrecognized tax benefits.

The Companies’ 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 (benefit) included in discontinued operations is $11 million and $(562) million for the six months ended June 30, 2021 and 2020, respectively.  2020 income taxes reflect a charge of $81 million for the write-off of tax-related regulatory assets associated with the Atlantic Coast Pipeline Project.

The 2019 Equity Units and the Q-Pipe Transaction deposit, prior to being settled in cash in July 2021, are potentially dilutive securities. See Note 19 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2020 and Note 3, respectively, for additional information. The forward stock purchase contracts included within the 2019 Equity Units were excluded from the calculation of diluted EPS from continuing operations for the three and six months ended June 30, 2021 and 2020, 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 will be settled in cash rather than through the issuance of Dominion Energy common stock. For the three and six months ended June 30, 2021, 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 periods. 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 six months ended June 30, 2021 based upon the expectation Dominion Energy would settle in cash rather than through the issuance of Dominion Energy common stock.

Fair Value Measurements

Fair Value Disclosures [Abstract]

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, 2020. See Note 9 in this report for further information about the Companies’ derivatives and hedge accounting activities.

The Companies enter into certain physical and financial forwards, futures, options and swaps, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical and financial forwards, futures and swaps contracts. An option model is used to value Level 3 physical options. The discounted cash flow model for forwards, futures and swaps 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 June 30, 2021.  The range and weighted average are presented in dollars for market price inputs and percentages for price volatility.

Nonrecurring Fair Value Measurements

In the second quarter of 2021, Dominion Energy recorded a charge of $20 million ($15 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income to write off substantially all of the long-lived assets of its nonregulated retail software development operations to their estimated fair value, using a market approach, of less than $1 million. The valuation is considered a Level 2 fair value measurement given that it is based on bids received.  

See Note 3 for information on the nonrecurring fair value measurement associated with the acquisition of Birdseye.

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:

	June 30, 2021				December 31, 2020
	Carrying Amount		Estimated Fair Value(1)		Carrying Amount		Estimated Fair Value(1)
(millions)
Dominion Energy
Long-term debt(2)(3)	$	33,076	$	38,558	$	31,996	$	38,773
Supplemental credit facility borrowings(4)		250		250		225		225
Junior subordinated notes(5)		2,862		3,024		3,411		3,633
Virginia Power
Long-term debt(5)	$	13,210	$	15,668	$	13,207	$	16,455

(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 both June 30, 2021 and December 31, 2020, the carrying amount includes the valuation of certain fair value hedges associated with fixed rate debt of $3 million.

(3) Includes amounts classified as held for sale, see Note 3.

(4) Also includes Supplemental 364-Day credit facility borrowings.

(5) Carrying amount includes current portions included in securities due within one year and amounts which represent the unamortized debt issuance costs, discount or premium.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

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, 2020. See Note 8 in this report for further information about fair value measurements and associated valuation methods for derivatives.

Derivative assets and liabilities are presented gross on the Companies’ Consolidated Balance Sheets. 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 securities, none of which are subject to restrictions. Cash collateral, as presented in the table below, is used to offset derivative assets and liabilities.  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 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 further information regarding credit-related contingent features for the Companies’ derivative instruments.

Volumes

The following table presents the volume of Dominion Energy’s derivative activity at June 30, 2021. These volumes are based on open derivative positions and represent the combined absolute value of their long and short positions, except in the case of offsetting transactions, for which they represent the absolute value of the net volume of its long and short positions.

	Current		Noncurrent
Natural Gas (bcf):
Fixed price(1)		59		14

AOCI

The following table presents selected information related to losses on cash flow hedges included in AOCI in Dominion Energy’s Consolidated Balance Sheet at June 30, 2021:

	AOCI After-Tax			Amounts Expected to be Reclassified to Earnings During the Next 12 Months After-Tax			Maximum Term
(millions)
Interest rate	$	(371	)	$	(43	)	390 months
Total	$	(371	)	$	(43	)

The amounts that will be reclassified from AOCI to earnings will generally be offset by the recognition of the hedged transactions (e.g., interest rate payments) in earnings, thereby achieving the realization of prices contemplated by the underlying risk management strategies and will vary from the expected amounts presented above as a result of changes in interest rates.

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 six months ended June 30, 2021 and 2020.

The following table presents the amounts recorded on the balance sheet related to cumulative basis adjustments for fair value hedges:

	Carrying Amount of the Hedged Asset (Liability)(1)						Cumulative Amount of Fair Value Hedging Adjustments Included in the Carrying Amount of the Hedged Assets (Liabilities)(2)

Equity Method Investments

Dominion Energy recorded equity earnings on its investments of $145 million and $5 million for the six months ended June 30, 2021 and 2020, respectively, in earnings from equity method investees in its Consolidated Statements of Income.  In addition, Dominion Energy recorded equity losses of $22 million and $2.3 billion for the six months ended June 30, 2021 and 2020, respectively, in discontinued operations related to its investment in Atlantic Coast Pipeline.  Dominion Energy received distributions of $166 million and $46 million for the six months ended June 30, 2021 and 2020, respectively. Dominion Energy made contributions of $1.0 billion and $37 million for the six months ended June 30, 2021 and 2020 respectively. At June 30, 2021, Dominion Energy had $20 million of contributions payable to equity method affiliates included within other current liabilities in its Consolidated Balance Sheet. At June 30, 2021 and December 31, 2020, the net difference between the carrying amount of Dominion Energy’s investments and its share of underlying equity in net assets was $234 million and $213 million, respectively. At June 30, 2021, these differences are comprised of $27 million of equity method goodwill that is not being amortized, a $224 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 $(17) million basis difference primarily attributable to an unfunded commitment made to Align RNG.  At December 31, 2020, these differences are comprised of $27 million of equity method goodwill that is not being amortized, a $227 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 $(41) million basis difference primarily attributable to an unfunded commitment made to Align RNG.

Cove Point

In November 2020, in conjunction with the GT&S Transaction, Dominion Energy sold 100% of its general partner interest and 25% of the total limited partner interest in Cove Point. Dominion Energy retained 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, 2020.

Income before income taxes recorded by Cove Point was $136 million and $131 million for the three months ended June 30, 2021 and 2020, respectively, and $274 million and $264 million for the six months ended June 30, 2021 and 2020, respectively. For the periods prior to closing of the GT&S Transaction, earnings attributable to Dominion Energy are presented in discontinued operations and subsequent to the closing, earnings attributable to Dominion Energy are presented within earnings from equity method investees in its Consolidated Statements of Income.

Dominion Energy recorded distributions from Cove Point of $77 million and $150 million for the three and six months ended June 30, 2021, respectively.  No contributions were made to Cove Point for the three and six months ended June 30, 2021.

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, 2020.

At June 30, 2021 and December 31, 2020, Dominion Energy has recorded a liability of $115 million and $1.1 billion, respectively, 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 credit facility, through February 2021, and AROs.

In February 2021, Atlantic Coast Pipeline repaid the outstanding borrowed amounts and terminated its revolving credit facility. As of December 31, 2020, Atlantic Coast Pipeline had borrowed $1.8 billion against the revolving credit facility.  Concurrently, Dominion Energy’s related guarantee agreement to support its portion of Atlantic Coast Pipeline’s borrowings was also terminated. Dominion Energy’s Consolidated Balance Sheets included a liability of $6 million associated with this guarantee agreement at December 31, 2020.

Dominion Energy recorded contributions of $13 million during the three months ended June 30, 2020, and $965 million and $29 million during the six months ended June 30, 2021 and 2020, respectively, to Atlantic Coast Pipeline. Dominion Energy recorded no contributions during the three months ended June 30, 2021 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.

DETI provided services to Atlantic Coast Pipeline which totaled $17 million and $37 million for the three and six months ended June 30, 2020, respectively, included in discontinued operations in Dominion Energy’s Consolidated Statements of Income.

Dominion Energy has claimed or expects to claim federal investment tax credits on the projects.

Non-Wholly-Owned Nonregulated Solar Facilities

Sale to Terra Nova Renewable Partners

In August 2021, Dominion Energy entered into an agreement with Terra Nova Renewable Partners to sell SBL Holdco, which holds Dominion Energy’s remaining 67% controlling interest in certain nonregulated solar projects for consideration of approximately $450 million, subject to customary closing adjustments, with the amount of cash reduced by the amount of SBL Holdco’s debt outstanding at closing. The transaction is expected to close in the fourth quarter of 2021, contingent on clearance or approval under the Hart-Scott-Rodino Act and by FERC as well as other customary closing and regulatory conditions.  

Dominion Energy will reclassify the assets and liabilities to be disposed of as held for sale in the third quarter of 2021. Dominion Energy expects to record a gain of approximately $25 million ($27 million after-tax) upon closing.

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, 2020.

Virginia Regulation

2021 Triennial Review

In March 2021, Virginia Power filed its base rate case and accompanying schedules in support of the 2021 Triennial Review. In its filing, Virginia Power did not request an increase in base rates for generation and distribution services and proposed that base rates remain at their existing level. Virginia Power’s earnings test analysis, as filed, demonstrates it earned a combined ROE of 10.85% on its generation and distribution services for the test period, before accounting for forgiven customer balances. Pursuant to Virginia legislation, forgiven customer balances are excluded from the cost of service in determining test period revenues as part of the 2021 Triennial Review. To the extent that the Virginia Commission determines total earnings for the test period to be above Virginia Power’s authorized earnings band, the forgiven balance amounts are offset against the available revenues in the determination of any customer bill credits, or utilization of a CCRO. Test period earnings may be further reduced by Virginia Commission approved investment amounts in qualifying solar or wind generation facilities or electric distribution grid transformation projects that Virginia Power elects to include as a CCRO under the GTSA. In its filing, Virginia Power has elected to utilize $26 million of the Coastal Virginia Offshore Wind Pilot project investment as a CCRO to offset available revenues. The Virginia Commission will determine whether Virginia Power’s earnings for the test period, considered as a whole, were within 70 basis points above or below the authorized ROE of 9.2%. Should the Virginia Commission determine that there are additional available revenues for earnings sharing, then Virginia Power has contingently elected to offset those revenues with additional Virginia Commission approved qualifying CCRO investments. The Virginia Commission will also authorize an ROE for Virginia Power that will be applied to Virginia Power’s riders prospectively and that will also be utilized to measure base rate earnings as of January 1, 2021. Virginia Power is requesting authorization of an ROE of 10.8% based on Virginia Power’s current cost of equity. Pursuant to the Regulation Act, Virginia Power’s authorized ROE shall not be set lower than the average of either (i) the returns reported for the three previous years by not less than a majority of comparable utilities in the Southeastern U.S., with certain limitations as described in the Regulation Act, or (ii) the authorized returns that are set by the applicable regulatory commissions for the same select peer group. In May 2021, Virginia Power filed supplemental testimony to reflect updated test period earnings, including an earned ROE of 10.42%, before accounting for forgiven customer balances, and that no amount of eligible CCRO is necessary to be elected to be utilized. This matter is pending.

In the third and fourth quarters of 2020, Virginia Power recorded a net charge of $130 million related to the use of a CCRO in accordance with the GTSA.  In the first quarter of 2021, Virginia Power recorded a benefit of $130 million ($97 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income to adjust its reserve related to the use of a CCRO in accordance with the GTSA. These amounts reflect the impact related to jurisdictional customers as a result of the 2021 Triennial Review as well as the impact on certain non-jurisdictional customers which follow Virginia Power’s jurisdictional customer rate methodology.

Utility Disconnection Moratorium Legislation

In November 2020, legislation was enacted in Virginia relating to the moratorium on utility disconnections during the COVID-19 pandemic and resulted in Virginia Power forgiving Virginia jurisdictional retail electric customer balances that were more than 30 days past due as of September 30, 2020. As a result, Virginia Power recorded a charge of $127 million in the fourth quarter of 2020.  

In connection with the Virginia 2021 budget process, in the first quarter of 2021 Virginia Power recorded a charge of $76 million ($56 million after-tax) in impairment of assets and other charges in its Consolidated Statements of Income for Virginia jurisdictional retail electric customer balances that were more than 30 days past due as of December 31, 2020 that Virginia Power is required to forgive.  These forgiven customer balances are factored into Virginia Power’s 2021 Triennial Review as discussed above.

Grid Transformation and Security Act of 2018

In June 2021, Virginia Power filed a petition with the Virginia Commission for approval of a plan for electric distribution grid transformation projects as authorized by the GTSA.  The plan includes 14 projects covering six components: (i) smart meters; (ii) customer information platform; (iii) grid improvement projects; (iv) physical and cyber security; (v) telecommunications infrastructure and (vi) customer education (Phase II). For Phase II, the total proposed capital investment during 2022 – 2023 is $669 million and the proposed operations and maintenance investment is $110 million.  This matter is pending.

Virginia Fuel Expenses

In May 2021, Virginia Power filed its annual fuel factor with the Virginia Commission to recover an estimated $1.4 billion in Virginia jurisdictional projected fuel expenses for the rate year beginning July 1, 2021 and $72 million of estimated net under-recovered balances through June 30, 2021.  In June 2021, the Virginia Commission approved the annual fuel factor.

Solar Facility Projects

In May 2020 and July 2020, Virginia Power entered into and closed on separate agreements to acquire Grassfield Solar, Norge Solar and Sycamore Solar. The projects are expected to cost approximately $170 million in aggregate once constructed, including the initial acquisition cost. The facilities are expected to generate 82 MW combined and be placed into service in 2022. In October 2020, Virginia Power filed an application with the Virginia Commission for CPCNs to construct and operate these projects as part of its efforts to meet the renewable generation development requirements under the VCEA.  In April 2021, the Virginia Commission approved the application.

Riders

Below is a discussion of significant riders associated with various Virginia Power projects:

• The Virginia Commission previously approved Rider U in conjunction with cost recovery to move certain electric distribution facilities underground as authorized by Virginia legislation. In June 2020, Virginia Power proposed an $80 million total revenue requirement consisting of $44 million for previously approved phases and $36 million for phase five costs for Rider U for the rate year beginning April 1, 2021. This total revenue requirement represents a $28 million increase over the previous year. In February 2021, the Virginia Commission approved the filing.

In June 2021, Virginia Power proposed a $96 million total revenue requirement consisting of $61 million for previously approved phases and $35 million for phase six costs for Rider U for the rate year beginning April 1, 2022. This total revenue requirement represents a $16 million increase over the previous year. This matter is pending.

• Pursuant to Virginia legislation, Virginia Power can recover the costs related to the closure of CCR units.  In February 2021, Virginia Power filed for approval of Rider CCR with a proposed $216 million revenue requirement for the rate year beginning December 1, 2021.  This matter is pending.

• In October 2020, Virginia Power applied for approval of Rider CE associated with Grassfield Solar, Norge Solar and Sycamore Solar described above.  In April 2021, the Virginia Commission approved a $10 million revenue requirement for the rate year beginning June 1, 2021.

• The Virginia Commission previously approved Rider T1 concerning transmission rates. In May 2021, Virginia Power proposed a $874 million total revenue requirement consisting of $493 million for the transmission component of Virginia Power’s base rates and $381 million for Rider T1 for the rate year beginning September 1, 2021. This total revenue requirement represents a $190 million decrease versus the revenues to be produced during the rate year under current rates.  This matter is pending.

• Pursuant to the VCEA, Virginia Power can recover costs of compliance with the mandatory renewable portfolio standard program. In December 2020, Virginia Power filed for approval of Rider RPS with a proposed $13 million revenue requirement for the rate year beginning August 1, 2021. In July 2021, the Virginia Commission approved the filing.

• The Virginia Commission previously approved Rider GV relating to Greensville County.  In June 2021, Virginia Power proposed a biennial update procedure for Rider GV with two consecutive rate years. The filing proposed a revenue requirement of $142 million for the rate year beginning April 1, 2022 and a revenue requirement of $127 million for the rate year beginning April 2023.  This matter is pending.

• The Virginia Commission previously approved Rider R relating to Bear Garden. In June 2021, Virginia Power proposed a biennial update procedure for Rider R with two consecutive rate years. The filing proposed a revenue requirement of $59

million for the rate year beginning April 1, 2022 and a revenue requirement of $55 million for the rate year beginning April 1, 2023.  This matter is pending.

• The Virginia Commission previously approved Rider S relating to Virginia City Hybrid Energy Center. In June 2021, Virginia Power proposed a biennial update procedure for Rider S with two consecutive rate years. The filing proposed a revenue requirement of $192 million for the rate year beginning April 1, 2022 and a revenue requirement of $191 million for the rate year beginning April 1, 2023.  This matter is pending.

• Pursuant to Virginia legislation, Virginia Power can recover costs associated with participating in a market-based carbon trading program consistent with RGGI.  In August 2021, the Virginia Commission approved Rider RGGI with a $168 million revenue requirement for the rate year beginning September 1, 2021.

Additional significant riders associated with various Virginia Power projects are as follows:

North Carolina Regulation

PSNC Base Rate Case

In April 2021, PSNC filed its general rate case application, direct testimony, exhibits, and schedules with the North Carolina Commission.  PSNC proposed a non-fuel, base rate increase of $53 million to be effective November 1, 2021. After considering the benefits of the 2017 Tax Reform Act, the net revenue increase to customers would be approximately $42 million.  The base rate increase was proposed to recover the significant investment in infrastructure to serve a growing customer base, improve safety and reliability of the transmission and distribution system and enhance energy efficiency and sustainability.  The proposed rates would provide for an ROE of 10.25% compared to the currently authorized ROE of 9.7%.  This matter is pending.

South Carolina Regulation

South Carolina Electric Base Rate Case

In August 2020, DESC filed its retail electric base rate case and schedules with the South Carolina Commission. DESC proposed a non-fuel, base rate increase of $178 million, or 7.75%, based on an adjusted test year data, effective on or after the first billing cycle of

March 2021. The base rate increase was proposed to recover the significant investment in assets and operating resources required to serve an expanding customer base, maintain the safety, reliability and efficiency of DESC’s system and meet increasingly stringent reliability, security and environmental requirements for the benefit of South Carolina customers.  DESC presented an earned ROE of 5.90% based upon a fully-adjusted test period. The proposed rates would provide for an earned ROE equal to the current authorized earned ROE of 10.25% established in the previous rate case in 2012. In January 2021, the South Carolina Commission approved a proposal made by the South Carolina Office of Regulatory Staff, and agreed to by DESC and other intervenors, to stay the base rate case due to the current economic conditions and to allow the parties more time to negotiate a settlement with a final order to be issued no later than August 2021.  

In July 2021, DESC, the South Carolina Office of Regulatory Staff and other parties of record filed a comprehensive settlement agreement with the South Carolina Commission for approval. The comprehensive settlement agreement provides for a non-fuel, base rate increase of $62 million (resulting in a net increase of $36 million after considering an accelerated amortization of certain excess deferred income taxes) commencing with bills issued on September 1, 2021 and an authorized earned ROE of 9.50%. Additionally, DESC has agreed to commit up to $15 million to forgive retail electric customer balances that were more than 60 days past due as of May 31, 2021, and provide $15 million for energy efficiency upgrades and critical health and safety repairs to customer homes. Pursuant to the comprehensive settlement agreement, DESC would not file a retail electric base rate case prior to July 1, 2023, such that new rates would not be effective prior to January 1, 2024, absent unforeseen extraordinary economic or financial conditions that may include changes in corporate tax rates. In July 2021, the South Carolina Commission voted to approve the comprehensive settlement agreement with a final order expected to be issued in August 2021.

In connection with this matter, Dominion Energy recorded charges for both the three and six months ended June 30, 2021, of $249 million ($187 million after-tax) reflected within impairment of assets and other charges, including $237 million of regulatory assets associated with DESC’s purchases of its first mortgage bonds during 2019 that are no longer probable of recovery under the settlement agreement, and $18 million ($14 million after-tax) reflected within other income in its Consolidated Statements of Income.

DSM Programs

DESC has approval for a DSM rider through which it recovers expenditures related to its DSM programs. In January 2021, DESC filed an application with the South Carolina Commission seeking approval to recover $48 million of costs and net lost revenues associated with these programs, along with an incentive to invest in such programs. In April 2021, the South Carolina Commission approved the filing. In connection with the approval of the comprehensive settlement agreement in the South Carolina base rate case discussed above, the net lost revenue component of the DSM rider will be adjusted resulting in a recovery of $43 million commencing with bills issued on September 1, 2021.

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 2021, DESC filed a proposal with the South Carolina Commission to increase the total fuel cost component of retail electric rates. DESC’s proposed adjustment would increase annual base fuel component recoveries by $36 million and is designed to recover DESC’s current base fuel costs, net of the existing over-collected balance, over the 12-month period beginning with the first billing cycle of May 2021. In addition, DESC proposed a decrease to its variable environmental component and an increase to its distributed energy resource component. In April 2021, the South Carolina Commission approved the filing.

Natural Gas Rates

In June 2021, DESC filed with the South Carolina Commission its monitoring report for the 12-month period ended March 31, 2021 with a total revenue requirement of $426 million. This represents a $9 million overall annual increase to its natural gas rates under the terms of the Natural Gas Rate Stabilization Act effective with the first billing cycle of November 2021. This matter is pending.

Ohio Regulation

PIR Program

In 2008, East Ohio began PIR, aimed at replacing approximately 25% of its pipeline system. In April 2021, the Ohio Commission approved East Ohio’s application to adjust the PIR cost recovery rates for 2020 costs. The filing reflects gross plant investment for 2020 of $178 million, cumulative gross plant investment of $2.0 billion and an annual revenue requirement of $243 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 2021, East Ohio filed an application requesting approval to adjust the CEP cost recovery rates for 2019 and 2020 costs.  The filing reflects gross plant investment for 2019 of $137 million, gross plant investment for 2020 of $99 million, cumulative gross plant investment of $957 million and a revenue requirement of $119 million. This matter is pending.

UEX Rider

East Ohio has approval for a UEX Rider through which it recovers the bad debt expense of most customers not participating in the PIPP Plus Program. The UEX Rider is adjusted annually to achieve dollar for dollar recovery of East Ohio’s actual write-offs of uncollectible amounts. In May 2021, East Ohio filed an application with the Ohio Commission requesting approval of its UEX Rider to reflect an increased annual revenue requirement of $20 million to provide for an under-recovered accumulated bad debt expense of $7 million as of March 31, 2021, and recovery of net bad debt expense projected to total $13 million for the twelve-month period ending March 2022. In July 2021, the Ohio Commission approved the filing.

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%.

PREP

In May 2021, Hope filed a PREP application with the West Virginia Commission requesting approval to recover PREP costs related to $54 million and $56 million of projected capital investment for 2021 and 2022, respectively. The application also includes a true-up of PREP costs related to the 2020 actual capital investment of $34 million and sets forth $9 million of annual PREP costs to be recovered in proposed rates effective November 1, 2021. This matter is pending.

Utah Regulation

Purchased Gas

In May 2021, the Utah Commission approved Questar Gas’ request for a $43 million gas cost increase with rates effective June 2021.

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.

Dominion Energy

In June 2021, Dominion Energy amended its $6.0 billion joint revolving credit facility to provide 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. In addition, the amended facility incorporates certain administrative changes with respect to the anticipated transition from LIBOR to an alternative benchmark rate. The key financial covenants are unchanged from the previous facility.

At June 30, 2021, 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	$	2,636	$	99	$	3,265

(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 June 30, 2021, the sub-limits for DESC and Questar Gas were $500 million and $250 million, respectively.

In January 2021, DESC and GENCO applied to FERC for a two-year short-term borrowing authorization. In March 2021, FERC granted DESC authority through March 2023 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 2021, FERC granted GENCO authority through March 2023 to issue short-term indebtedness not to exceed $200 million outstanding with maturity dates of one year or less.

In addition to the credit facilities 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 matures in June 2022. At June 30, 2021 and December 31, 2020, Dominion Energy had $29 million and $30 million in letters of credit outstanding under this agreement, respectively.

In addition to the credit facilities mentioned above, SBL Holdco has $30 million of credit facilities which had an original stated maturity date of December 2017 with automatic one-year renewals through the maturity of the SBL Holdco term loan agreement in 2023. Dominion Solar Projects III, Inc. has $25 million of credit facilities which had an original stated maturity date of May 2018 with automatic one-year renewals through the maturity of the Dominion Solar Projects III, Inc. term loan agreement in 2024. At both June 30, 2021 and December 31, 2020, no amounts were outstanding under either of these facilities.

In March 2020, Dominion Energy entered into a $900 million 364-Day Revolving Credit Agreement that bore interest at a variable rate. At December 31, 2020, $225 million was outstanding under the agreement. In March 2021, the agreement reached maturity and Dominion Energy repaid the outstanding borrowed amount in full.

In July 2021, Dominion Energy entered into an approximately $1.3 billion term loan credit agreement following the termination of the Q-Pipe Transaction as discussed in Note 3.

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 Investment^SM 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, 2020. At June 30, 2021 and December 31, 2020, Dominion Energy’s Consolidated Balance Sheets include $392 million and $268 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, as amended in June 2021. The facility can be used for working capital, as support for the combined commercial paper programs of Virginia Power, Dominion Energy, Questar Gas and DESC and for other general corporate purposes.

At June 30, 2021, 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	$	814	$	12

(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 June 30, 2021, 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 March 2021, PSNC issued, through private placement, $150 million of 3.10% senior notes that mature in 2051.

In April 2021, Dominion Energy issued $600 million of 1.45% senior notes and $500 million of 3.30% senior notes that mature in 2026 and 2041, respectively.

In June 2021, Questar Gas entered into an agreement with certain investors to issue through private placement in August 2021, $125 million 2.21% 10-year senior notes and $125 million 3.15% 30-year senior notes.

In June 2021, Dominion Energy entered into a $900 million Sustainability Revolving Credit Agreement. This supplemental credit facility, which matures in June 2024 and bears interest at a variable rate, offers a reduced interest rate margin with respect to borrowed amounts allocated to certain environmental sustainability or social investment initiatives. Proceeds of the supplemental credit facility also may be used for general corporate purposes, but such proceeds are not eligible for a reduced interest rate margin. At June 30, 2021, $250 million was outstanding under the supplemental credit facility. The proceeds from these borrowings were used to support environmental sustainability and social investment initiatives.  The maximum allowed total debt to total capital ratio under this supplemental credit facility is consistent with such allowed ratio under Dominion Energy’s joint revolving credit facility.

In July 2021, DESC redeemed the remaining principal outstanding of $30 million of its 3.22% first mortgage bonds, plus accrued interest. The bonds would have otherwise matured in October 2021.

In July 2021, Dominion Energy redeemed the remaining principal outstanding of $400 million of its 2.0% senior notes, plus accrued interest. The notes would have otherwise matured in August 2021.

Preferred Stock

Dominion Energy is authorized to issue up to 20 million shares of preferred stock, which may be designated into separate classes.  At both June 30, 2021 and December 31, 2020, Dominion Energy had issued and outstanding 2.4 million shares of preferred stock, 1.6 million and 0.8 million of which were designated as the Series A Preferred Stock and the Series B Preferred Stock, respectively.  Dominion Energy’s Series A Preferred Stock and Series B Preferred Stock 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, 2020.  

Dominion Energy recorded dividends of $7 million ($4.375 per share) for both the three months ended June 30, 2021 and 2020, and $14 million ($8.750 per share) for both the six months ended June 30, 2021 and 2020, on the Series A Preferred Stock. Dominion Energy also recorded dividends of $9 million ($11.625 per share) for both the three months ended June 30, 2021 and 2020, and $18 million ($23.250 per share) for both the six months ended June 30, 2021 and 2020, on Series B Preferred Stock. The stock purchase contract liability associated with Dominion Energy’s 2019 Equity Units was $87 million and $129 million at June 30, 2021 and December 31, 2020, respectively. Stock purchase contract payments of $42 million and $41 million were made during the six months ended June 30, 2021 and 2020, respectively. In calculating diluted EPS, Dominion Energy applies the treasury stock method to the stock purchase contracts and the if-converted method to the Series A Preferred Stock.  

Issuance of Common Stock

Dominion Energy recorded, net of fees and commissions, $97 million from the issuance of 1 million shares of common stock for the six months ended June 30, 2021 and $148 million from the issuance of 2 million shares of common stock for the six months ended June 30, 2020, 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, 2020.

In July 2021, Dominion Energy issued 1.4 million shares of its common stock, valued at $104 million, to satisfy DESC’s obligation under a settlement agreement for the FILOT litigation discussed in Note 17.

In August 2021, Dominion Energy issued 0.6 million shares of its common stock, valued at $45 million, to satisfy DESC’s obligation for the initial payment under a settlement agreement with the SCDOR discussed in Note 17.

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, 2020. As of June 30, 2021, Dominion Energy has not issued any shares or entered into any forward sale agreements under this program.

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 as discussed in Note 20 to the Consolidated Financial Statements in the Companies’ Annual Report Form 10-K for the year ended December 31, 2020. Dominion Energy did not repurchase any shares of common stock during the six months ended June 30, 2021.

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. 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. Until the states have developed implementation plans for the standard, 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. While the EPA has stated its intention to replace the ACE Rule, it is unknown at this time if or how the EPA will issue a replacement for the ACE Rule and how that replacement will affect the Companies’ 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. In January 2021, the EPA published a final rule affirming that fossil fuel-fired electric generating units meet the requirement that a source category “significantly contribute” to endangering air pollution for the purposes of regulating GHG emissions from new, modified and reconstructed stationary sources. The January 2021 rule also established a threshold for the “significant contribution” threshold that would have meant that no other source category, such as oil and gas facilities, petroleum refineries, and boilers, would meet that requirement at this time. In April 2021, the U.S. Court of Appeals for the D.C. Circuit granted an unopposed motion by the EPA to vacate and remand the January 2021 rule. 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 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, technology, cost and 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 12 sites associated with Dominion Energy, including certain sites acquired in the SCANA Combination, remediation work has been substantially completed under federal or state oversight. Where required, the sites are following state-approved groundwater monitoring programs. Dominion Energy has proposed remediation plans associated with three sites, including one at Virginia Power, and expects to commence remediation activities in 2021 or 2022 depending on receipt of final permits and approvals. At June 30, 2021 and December 31, 2020, Dominion Energy had $40 million and $42 million, respectively, and Virginia

Power had $25 million and $26 million, respectively, of reserves recorded. In addition, for one site associated with Dominion Energy, an updated work plan submitted to SCDHEC in September 2018, would increase costs by approximately $11 million if approved by federal and state agencies. In September 2020, this plan was submitted to the Army Corps of Engineers. 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 to events occurring before closing of the SCANA Combination. 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 June 30, 2021 and December 31, 2020 include reserves of $341 million and $208 million, respectively, included within other current liabilities, and insurance receivables of $56 million and $8 million, respectively, included within other receivables. During the three and six months ended June 30, 2021, Dominion Energy’s Consolidated Statements of Income include charges of $40 million ($30 million after-tax) and $100 million ($75 million after-tax), respectively, included within impairment of assets and other charges. During the six months ended June 30, 2020, Dominion Energy’s Consolidated Statements of Income include charges of $25 million ($25 million after-tax) included within other income (expense).

Ratepayer Class Actions

In May 2018, a consolidated complaint against DESC, SCANA and the State of South Carolina was filed in the State Court of Common Pleas in Hampton County, South Carolina (the DESC Ratepayer Case). The plaintiffs alleged, among other things, that DESC was negligent and unjustly enriched, breached alleged fiduciary and contractual duties and committed fraud and misrepresentation in failing to properly manage the NND Project, and that DESC committed unfair trade practices and violated state anti-trust laws. In December 2018, the State Court of Common Pleas in Hampton County entered an order granting preliminary approval of a class action settlement. The court entered an order granting final approval of the settlement in June 2019, which became effective in July 2019. The settlement agreement, contingent upon the closing of the SCANA Combination, provided that SCANA and DESC establish an escrow account and proceeds from the escrow account would be distributed to the plaintiffs, after payment of certain taxes, attorneys' fees and other expenses and administrative costs. The escrow account would include (1) up to $2.0 billion, net of a credit of up to $2.0 billion in future electric bill relief, which would inure to the benefit of the escrow account in favor of class members over a period of time established by the South Carolina Commission in its order related to matters before the South Carolina Commission related to the NND Project, (2) a cash payment of $115 million and (3) the transfer of certain DESC-owned real estate or sales proceeds from the sale of such properties, which counsel for the plaintiffs estimated to have an aggregate value between $60 million and $85 million. At the closing of the SCANA Combination, SCANA and DESC funded the cash payment portion of the escrow account. In July 2019, DESC transferred $117 million representing the cash payment, plus accrued interest, to the plaintiffs. Through August 2020, property, plant and equipment with a net recorded value of $27 million had been transferred to the plaintiffs in coordination with the court-appointed real estate trustee to satisfy the settlement agreement. In September 2020, the court entered an order approving a final resolution of the transfer of real estate or sales proceeds with a cash contribution of $38.5 million by DESC and the conveyance of property, plant and equipment with a net recorded value of $3 million, which was completed by DESC in October 2020.

In September 2017, a purported class action was filed by Santee Cooper ratepayers against Santee Cooper, DESC, Palmetto Electric Cooperative, Inc. and Central Electric Power Cooperative, Inc. in the State Court of Common Pleas in Hampton County, South Carolina (the Santee Cooper Ratepayer Case). The allegations were substantially similar to those in the DESC Ratepayer Case. In March 2020, the parties executed a settlement agreement relating to this matter as well as the Luquire Case and the Glibowski Case described below. The settlement agreement provided that Dominion Energy and Santee Cooper establish a fund for the benefit of class members in the amount of $520 million, of which Dominion Energy’s portion was $320 million of shares of Dominion Energy common stock. In July 2020, the court issued a final approval of the settlement agreement. In September 2020, Dominion Energy issued $322 million of shares of Dominion Energy common stock to satisfy its obligation under the settlement agreement, including interest charges.

In July 2019, a similar purported class action was filed by certain Santee Cooper ratepayers against DESC, SCANA, Dominion Energy and former directors and officers of SCANA in the State Court of Common Pleas in Orangeburg, South Carolina (the Luquire Case). In August 2019, DESC, SCANA and Dominion Energy were voluntarily dismissed from the case. The claims were similar to the Santee Cooper Ratepayer Case. In March 2020, the parties executed a settlement agreement as described above relating to this matter as well as the Santee Cooper Ratepayer Case and the Glibowski Case. This case was dismissed as part of the Santee Cooper Ratepayer Case settlement described above.

RICO Class Action

In January 2018, a purported class action was filed, and subsequently amended, against SCANA, DESC and certain former executive officers in the U.S. District Court for the District of South Carolina (the Glibowski Case). The plaintiff alleged, among other things, that SCANA, DESC and the individual defendants participated in an unlawful racketeering enterprise in violation of RICO and conspired to violate RICO by fraudulently inflating utility bills to generate unlawful proceeds. In March 2020, the parties executed a settlement agreement as described above relating to this matter as well as the Santee Cooper Ratepayer Case and the Luquire Case. This case was dismissed as part of the Santee Cooper Ratepayer Case settlement described above.

SCANA Shareholder Litigation

In September 2017, a purported class action was filed against SCANA and certain former executive officers and directors in the U.S. District Court for the District of South Carolina. Subsequent additional purported class actions were separately filed against all or nearly all of these defendants (collectively the SCANA Securities Class Action). In January 2018, the U.S. District Court for the District of South Carolina consolidated these suits, and the plaintiffs filed a consolidated amended complaint in March 2018. The plaintiffs alleged, among other things, that the defendants violated §10(b) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder, and that the individually named defendants are liable under §20(a) of the same act. In December 2019, the parties executed a settlement agreement pursuant to which SCANA would pay $192.5 million, up to $32.5 million of which could be satisfied through the issuance of shares of Dominion Energy common stock, subject to court approval. In February 2020, the U.S. District Court for the District of South Carolina granted preliminary approval of the settlement agreement, pending a fairness hearing, and granted final approval in July 2020. In March 2020, SCANA funded an escrow account with $160 million in cash and paid the balance of $32.5 million in cash in August 2020 to satisfy the settlement.

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 will be utilized to satisfy a portion of the Federal Court Merger Case and the State Court Merger Case 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 will be partially satisfied by the State Court Derivative Case settlement described above.

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.

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. This case is pending.

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. This case is pending.

FILOT Litigation and Related Matters

In November 2017, Fairfield County filed a complaint and a motion for temporary injunction against DESC in the State Court of Common Pleas in Fairfield County, South Carolina, making allegations of breach of contract, fraud, negligent misrepresentation, breach of fiduciary duty, breach of implied duty of good faith and fair dealing and unfair trade practices related to DESC’s termination of the FILOT agreement between DESC and Fairfield County related to the NND Project. The plaintiff sought a temporary and permanent injunction to prevent DESC from terminating the FILOT agreement. The plaintiff withdrew the motion for temporary injunction in December 2017. In July 2021, the parties executed a settlement agreement requiring DESC to pay $99 million, which could be satisfied in either cash or shares of Dominion Energy common stock. Also in July 2021, the State Court of Common Pleas in Fairfield County, South Carolina approved the settlement. In July 2021, Dominion Energy issued 1.4 million shares of Dominion Energy common stock to satisfy DESC’s obligation under the settlement agreement.

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 September and October 2017, SCANA was served with subpoenas issued by the U.S. Attorney’s Office for the District of South Carolina and the Staff of the SEC’s Division of Enforcement seeking documents related to the NND Project. In February 2020, the SEC filed a complaint against SCANA, two of its former executive officers and DESC in the U.S. District Court for the District of South Carolina alleging that the defendants violated federal securities laws by making false and misleading statements about the NND Project. In April 2020, SCANA and DESC reached an agreement in principle with the Staff of the SEC’s Division of Enforcement to settle, without admitting or denying the allegations in the complaint. In December 2020, the U.S. District Court for the District of

South Carolina issued an order approving the settlement which required SCANA to pay a civil monetary penalty totaling $25 million, and SCANA and DESC to pay disgorgement and prejudgment interest totaling $112.5 million, which disgorgement and prejudgment interest amount were deemed satisfied by the settlements in the SCANA Securities Class Action and the DESC Ratepayer Case. SCANA paid the civil penalty in December 2020. The SEC civil action against two former executive officers of SCANA remains pending and is currently subject to a stay granted by the court in June 2020 at the request of the U.S. Attorney’s Office for the District of South Carolina.

In addition, the South Carolina Law Enforcement Division is conducting a criminal investigation into the handling of the NND Project by SCANA and DESC. Dominion Energy is cooperating fully with the investigations by the U.S. Attorney’s Office and the South Carolina Law Enforcement Division, including responding to additional subpoenas and document requests. Dominion Energy has also entered into a cooperation agreement with the U.S. Attorney’s Office and the South Carolina Attorney General’s Office. The cooperation agreement provides that in consideration of its full cooperation with these investigations to the satisfaction of both agencies, neither such agency will criminally prosecute or bring any civil action against Dominion Energy or any of its current, previous, or future direct or indirect subsidiaries related to the NND Project. A former executive officer of SCANA entered a plea agreement with the U.S. Attorney’s Office and the South Carolina Attorney General’s Office in June 2020 and entered a guilty plea with the U.S. District Court for the District of South Carolina in July 2020. Another former executive officer of SCANA entered a plea agreement with the U.S. Attorney's Office and the South Carolina Attorney General's Office in November 2020 and entered guilty pleas in the U.S. District Court for the District of South Carolina and in South Carolina state court in February 2021. As a result of the pleas, Dominion Energy has terminated indemnity for these former executive officers related to these two cases.

Abandoned NND Project

DESC, for itself and as agent for Santee Cooper, entered into an engineering, construction and procurement contract with Westinghouse and WECTEC in 2008 for the design and construction of the NND Project, of which DESC’s ownership share is 55%. Various difficulties were encountered in connection with the project. The ability of Westinghouse and WECTEC to adhere to established budgets and construction schedules was affected by many variables, including unanticipated difficulties encountered in connection with project engineering and the construction of project components, constrained financial resources of the contractors, regulatory, legal, training and construction processes associated with securing approvals, permits and licenses and necessary amendments to them within projected time frames, the availability of labor and materials at estimated costs and the efficiency of project labor. There were also contractor and supplier performance issues, difficulties in timely meeting critical regulatory requirements, contract disputes, and changes in key contractors or subcontractors. These matters preceded the filing for bankruptcy protection by Westinghouse and WECTEC in March 2017, and were the subject of comprehensive analyses performed by SCANA and Santee Cooper.

Based on the results of SCANA’s analysis, and in light of Santee Cooper's decision to suspend construction on the NND Project, in July 2017, SCANA determined to stop the construction of the units and to pursue recovery of costs incurred in connection with the construction under the abandonment provisions of the Base Load Review Act or through other means. This decision by SCANA became the focus of numerous legislative, regulatory and legal proceedings. Some of these proceedings remain unresolved and are described above.

In September 2017, DESC, for itself and as agent for Santee Cooper, filed with the U.S. Bankruptcy Court for the Southern District of New York Proofs of Claim for unliquidated damages against each of Westinghouse and WECTEC. These Proofs of Claim were based upon the anticipatory repudiation and material breach by Westinghouse and WECTEC of the contract, and assert against Westinghouse and WECTEC any and all claims that are based thereon or that may be related thereto.

Westinghouse’s reorganization plan was confirmed by the U.S. Bankruptcy Court for the Southern District of New York and became effective in August 2018. In connection with the effectiveness of the reorganization plan, the contract associated with the NND Project was deemed rejected. DESC is contesting approximately $285 million of filed liens in Fairfield County, South Carolina. Most of these asserted liens are claims that relate to work performed by Westinghouse subcontractors before the Westinghouse bankruptcy, although some of them are claims arising from work performed after the Westinghouse bankruptcy.

Westinghouse has indicated that some unsecured creditors have sought or may seek amounts beyond what Westinghouse allocated when it submitted its reorganization plan to the U.S. Bankruptcy Court for the Southern District of New York. If any unsecured creditor is successful in its attempt to include its claim as part of the class of general unsecured creditors beyond the amounts in the bankruptcy reorganization plan allocated by Westinghouse, it is possible that the reorganization plan will not provide for payment in full or nearly in full to its pre-petition trade creditors. The shortfall could be significant.

DESC and Santee Cooper were responsible for amounts owed to Westinghouse for valid work performed by Westinghouse subcontractors on the NND Project after the Westinghouse bankruptcy filing until termination of the interim assessment agreement. In

December 2019, DESC and Santee Cooper entered into a confidential settlement agreement with W Wind Down Co LLC resolving claims relating to the interim assessment agreement.

Further, some Westinghouse subcontractors who have made claims against Westinghouse in the bankruptcy proceeding also filed against DESC and Santee Cooper in South Carolina state court for damages. Many of these claimants have also asserted construction liens against the NND Project site. DESC also intends to oppose these claims and liens. With respect to claims of Westinghouse subcontractors, DESC believes there were sufficient amounts previously funded during the interim assessment agreement period to pay such validly asserted claims. With respect to the Westinghouse subcontractor claims which relate to other periods, DESC understands that such claims will be paid pursuant to Westinghouse’s confirmed bankruptcy reorganization plan. DESC further understands that the amounts paid under the plan may satisfy such claims in full. Therefore, DESC believes that the Westinghouse subcontractors may be paid substantially (and potentially in full) by Westinghouse. While Dominion Energy cannot be assured that it will not have any exposure on account of unpaid Westinghouse subcontractor claims, which DESC is presently disputing, Dominion Energy believes it is unlikely that it will be required to make payments on account of such claims that would exceed the portion of the Toshiba Settlement allocated for such balances within the SCANA Merger Approval Order recorded in regulatory liabilities on Dominion Energy’s Consolidated Balance Sheets.

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, 2020.

In March 2021, the total liability protection per nuclear incident available to all participants in the Secondary Financial Protection Program decreased from $13.8 billion to $13.7 billion. In June 2021, the total liability protection per nuclear incident available to all participants in the Secondary Financial Protection Program decreased from $13.7 billion to $13.5 billion. These decreases do not impact Dominion Energy’s responsibility per active unit under the Price-Anderson Amendments Act of 1988.

Effective June 2021, Dominion Energy reduced the levels of nuclear property insurance coverage for each of the reactor sites at Millstone, North Anna and Surry from $1.70 billion to the NRC minimum requirement of $1.06 billion. As a result of this reduction in nuclear property insurance coverage, Dominion Energy and Virginia Power’s maximum retrospective premium assessment for the current annual policy period was reduced to $76 million and $35 million, respectively.

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, 2020, 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.

In June 2018, a lawsuit for Kewaunee was filed in the U.S. Court of Federal Claims for recovery of spent nuclear fuel storage costs incurred after 2013. In March 2019, Dominion Energy amended its filing for recovery of spent nuclear fuel storage to include costs incurred for the year ended December 31, 2018. This matter is pending.

Guarantees, Surety Bonds and Letters of Credit

Upon the closing of the GT&S Transaction, Dominion Energy retained its 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 June 30, 2021, Dominion Energy had issued an additional $25 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 June 30, 2021, Dominion Energy had issued the following subsidiary guarantees:

	Maximum Exposure
(millions)
Commodity transactions(1)	$	1,859
Nuclear obligations(2)		202
Solar(3)		463
Other(4)		1,257
Total(5)	$	3,781

(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. Also includes guarantees entered into by DGI on behalf of certain subsidiaries to facilitate the acquisition and 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 guarantees for the new corporate office property and 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, 2020.

Additionally, at June 30, 2021, Dominion Energy had purchased $168 million of surety bonds, including $94 million at Virginia Power, and authorized the issuance of letters of credit by financial institutions of $99 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, 2020.

At June 30, 2021, Dominion Energy’s credit exposure totaled $123 million, primarily related to price risk management activities. Of this amount, investment grade counterparties, including those internally rated, represented 79%. No single counterparty, whether investment grade or non-investment grade, exceeded $38 million of exposure. At June 30, 2021, Virginia Power’s exposure related to wholesale customers totaled $7 million. Of this amount, investment grade counterparties, including those internally rated, represented 60%. No single counterparty, whether investment grade or non-investment grade, exceeded $2 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 June 30, 2021 and December 31, 2020, Dominion Energy would have been required to post $35 million and $14 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 $20 million and $1 million of collateral at June 30, 2021 and December 31, 2020, respectively, related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. 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 $55 million and $15 million at June 30, 2021 and December 31, 2020, respectively, which does not include the impact of any offsetting asset positions.

If the credit-related contingent features underlying these instruments that are in a liability position and not fully collateralized with cash were fully triggered, Virginia Power would not have been required to post any additional collateral to its counterparties at June 30, 2021 and would have been required to post an additional $2 million of collateral to its counterparties at December 31, 2020.

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 June 30, 2021, Virginia Power’s derivative assets and liabilities with affiliates were $26 million and $1 million, respectively. At December 31, 2020, Virginia Power’s derivative assets and liabilities with affiliates were $3 million and $22 million, respectively. See Note 9 for more 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, 2020. At June 30, 2021 and December 31, 2020, 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 $479 million and $436 million, respectively.  At June 30, 2021 and December 31, 2020, 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 $392 million and $354 million, respectively.

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 June 30,				Six Months Ended June 30,

Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2021

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, 2020.

In the Companies’ opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position at June 30, 2021, their results of operations and changes in equity for the three and six months ended June 30, 2021 and 2020 and their cash flows for the six months ended June 30, 2021 and 2020. 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. At June 30, 2021, Dominion Energy owns 50% of the voting interests in Four Brothers and Three Cedars and has a controlling financial interest over the entities through its right to control operations. GIP’s ownership interest in Four Brothers and Three Cedars, Terra Nova Renewable Partners’ 33% interest in certain Dominion Energy nonregulated solar projects and Brookfield’s 25% interest in Cove Point (effective December 2019 until November 2020) are reflected as noncontrolling interest in Dominion Energy’s Consolidated Financial Statements. In August 2021, Dominion Energy entered into an agreement with Terra Nova Renewable Partners to sell its remaining controlling financial interest in certain nonregulated solar projects. See Note 11 for more information.

Reclassifications

Certain amounts in the Companies’ 2020 Consolidated Financial Statements and Notes have been reclassified to conform to the 2021 presentation for comparative purposes; however, such reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows. Effective in the second quarter of 2021, the Companies updated their Statements of Cash Flows to present net charges for allowance for credit risk and write-offs of accounts receivables within other adjustments to reconcile net income to net cash provided by operating activities from the previous presentation within changes in accounts receivable. All prior period information has been conformed to this presentation, which does not result in a change to net cash provided by operating activities.

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, 2020, with the exception of the items described below.

Property, Plant and Equipment

Property, Plant and Equipment

In March 2020, Virginia Power committed to retire certain coal- and oil-fired generating units before the end of their useful lives based on economic and other factors, including but not limited to market power prices and the VCEA. These units will be retired after they meet their capacity obligations to PJM in 2023. As a result, Virginia Power recorded a charge of $754 million ($561 million after-tax) in the first quarter of 2020, primarily included in impairment of assets and other charges in its Consolidated Statements of Income. This charge is considered a component of Virginia Power’s base rates deemed recovered under the GTSA, subject to review as

discussed in Note 13 to the Consolidated Financial Statements in Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2020.

In the second quarter of 2020, Virginia Power recorded charges of $30 million ($22 million after-tax) associated with dismantling certain of these electric generation facilities, recorded in impairment of assets and other charges 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, options and swaps, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical and financial forwards, futures and swaps contracts. An option model is used to value Level 3 physical options. The discounted cash flow model for forwards, futures and swaps 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. 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.
