Debt Disclosure [Abstract] |
Short-Term Debt and Credit Agreements | NOTE 17. SHORT-TERM DEBT AND CREDIT AGREEMENTS 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 Dominion Energy’s short-term financing is supported through its access to the joint revolving credit facility described below. Commercial paper and letters of credit outstanding, as well as capacity available under the credit facility were as follows:
|  | Facility Limit |  |  | Outstanding Commercial Paper(1) |  |  | Outstanding Letters of Credit |  |  | Facility Capacity Available |
(millions) |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

(3) | In October 2020, the joint revolving credit facility was amended to remove Dominion Energy Gas as a co-borrower.
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 December 31, 2020, the sub-limits for DESC and Questar Gas were $500 million and $250 million, respectively. In January 2020, DESC and GENCO applied to FERC for a two-year short-term borrowing authorization. In March 2020, FERC granted DESC authority through March 2021 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 2020, FERC granted GENCO authority through March 2021 to issue short-term indebtedness not to exceed $200 million outstanding with maturity dates of one year or less. In January 2021, DESC and GENCO applied to FERC for a two-year short-term borrowing authorization. The applications are pending. In addition to the credit facility mentioned above, Dominion Energy also has a credit facility which had an original stated maturity date of June 2020 and allowed Dominion Energy to issue up to $21 million in letters of credit. In May 2020, the credit facility was amended to increase the facility capacity to approximately $30 million and extend the maturity date to June 2022. At December 31, 2020 and 2019, Dominion Energy had $30 million and $21 million, respectively, in letters of credit outstanding under this agreement. 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 December 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 May 2024. At both December 31, 2020 and 2019, no amounts were outstanding under either of these facilities. In March 2020, Dominion Energy entered into a $900 million 364-Day Revolving Credit Agreement. The agreement bears interest at a variable rate. At December 31, 2020, $225 million was outstanding under the agreement. The proceeds from these borrowings were used to provide for general working capital and other general corporate purposes. The maximum allowed total debt to total capital ratio under this supplemental agreement is consistent with such allowed ratio under Dominion Energy’s joint revolving credit facility. In March 2020, Dominion Energy borrowed $500 million under a 364-Day Term Loan Credit Agreement that bore interest at a variable rate. The proceeds were used to provide for general working capital and other general corporate purposes. In November 2020, Dominion Energy repaid the outstanding balance in full. In April 2020, Dominion Energy borrowed $625 million under a 364-Day Term Loan Credit Agreement that bore interest at a variable rate. The proceeds were used to provide for general working capital and other general corporate purposes. In June 2020, Dominion Energy repaid the outstanding balance in full. Dominion Energy has an effective shelf registration statement with the SEC for the sale of up to $3.0 billion of variable denomination floating rate demand notes, called Dominion Energy Reliability InvestmentSM. 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 December 31, 2020 and December 31, 2019, Dominion Energy’s Consolidated Balance Sheets include $268 million and $75 million, respectively, 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 the joint revolving credit facility. The credit facility can be used for working capital, as support for the combined commercial paper programs of the borrowers under the credit facility and for other general corporate purposes. 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 were as follows:
|  | Facility Limit |  |  | Outstanding Commercial Paper(1) |  |  | Outstanding Letters of Credit |
(millions) |  |  |  |  |  |  |  |  |  |  |  |

(2) | 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 within the facility limit but can be changed at the option of the borrowers under the credit facility multiple times per year. At December 31, 2020, the sub-limit for Virginia Power was $1.5 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 March 2023 and 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.
