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 September 30, 2021, Dominion Energy’s credit exposure totaled $177 million, primarily related to price risk management activities. Of this amount, investment grade counterparties, including those internally rated, represented 91%. No single counterparty, whether investment grade or non-investment grade, exceeded $51 million of exposure. At September 30, 2021, Virginia Power’s exposure related to wholesale customers totaled $10 million. Of this amount, investment grade counterparties, including those internally rated, represented 80%. No single counterparty, whether investment grade or non-investment grade, exceeded $4 million of exposure. Credit-Related Contingent Provisions Certain of Dominion Energy’s derivative instruments contain credit-related contingent provisions. These provisions require Dominion Energy to provide collateral upon the occurrence of specific events, primarily a credit rating downgrade. If the credit-related contingent features underlying these instruments that are in a liability position and not fully collateralized with cash were fully triggered as of September 30, 2021 and December 31, 2020, Dominion Energy would have been required to post $102 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 $90 million and $1 million of collateral at September 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 $192 million and $15 million at September 30, 2021 and December 31, 2020, respectively, which does not include the impact of any offsetting asset positions. Certain of Virginia Power’s derivative instruments contain credit-related contingent provisions.

If the credit-related contingent features underlying these instruments that are in a liability position and not fully collateralized with cash were fully triggered as of September 30, 2021 and December 31, 2020, Virginia Power would have been required to post an additional $40 million and $2 million, respectively of additional collateral to its counterparties. The collateral that would be required to be posted includes the impacts of any offsetting asset position and any amounts already posted for derivatives and non-derivative contracts, per contractual terms. Virginia Power had posted $79 million of collateral at September 30, 2021 related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash.
