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 capital projects, commodity prices, hedging levels, Dominion Energy’s credit ratings and the credit quality of its counterparties. Other than the items discussed below, there have been no significant changes regarding the Companies’ credit facilities and short-term debt as described in Note 17 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2024.

Dominion Energy

Dominion Energy’s short-term financing is primarily supported by its joint revolving credit facility.

The key financial covenants in the facility are unchanged except for a technical clarification to the calculation of equity utilized in the total debt to total capital ratio.

DESC’s short-term financing is supported through its access as co-borrower to the joint revolving credit facility discussed above with the Companies. At June 30, 2025, the sub-limit for DESC was $1.0 billion, which was increased from $500 million in April 2025. In July 2025, the sub-limit for DESC was decreased to $900 million.

Virginia Power

Virginia Power’s short-term financing is supported through its access as co-borrower to Dominion Energy’s $7.0 billion joint revolving credit facility, as amended in April 2025.
