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, 2019. At June 30, 2020, Dominion Energy’s gross credit exposure related to energy marketing and price risk management activities totaled $215 million. Of this amount, investment grade counterparties, including those internally rated, represented 95%. No single counterparty, whether investment grade or non-investment grade, exceeded $53 million of exposure. At June 30, 2020, Virginia Power’s exposure related to wholesale customers totaled $59 million. Of this amount, investment grade counterparties, including those internally rated, represented 100%. No single counterparty, whether investment grade or non-investment grade, exceeded $53 million of exposure. At June 30, 2020, Dominion Energy Gas’ exposure primarily related to wholesale customers totaled $27 million. Of this amount, investment grade counterparties, including those internally rated, represented 88%. No single counterparty, whether investment grade or non-investment grade, exceeded $3 millio n of exposure. For the three and six months ended June 30, 2020, the Export Customers comprised approximately 36% and 34%, respectively, of Dominion Energy Gas’ total operating revenue, with Dominion Energy Gas’ largest customer representing approximately 19% and 18%, respectively, of such amounts during the periods. For the three and six months ended June 2019, the Export Customers comprised approximately 34% and 33%, respectively, of Dominion Energy Gas’ total operating revenue, with Dominion Energy Gas’ largest customer representing approximately 18% and 17%, respectively, of such amounts during the periods. Credit-Related Contingent Provisions The majority 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, 2020 and December 31, 2019, Dominion Energy would have been required to post $13 million and $10 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 $4 million of collateral at June 30, 2020 related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash and had posted no collateral at December 31, 2019. 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 $17 million and $10 million at June 30, 2020 and December 31, 2019, 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 as of June 30, 2020 and December 31, 2019, Virginia Power would have been required to post an additional $2 million and $8 million, respectively, of collateral to its counterparties. Credit-related contingent provisions for Dominion Energy Gas were not material as of June 30, 2020 and December 31, 2019. See Note 9 for further information about derivative instruments.
