DESC's short-term financing is supported through its access as co-borrower to Dominion Energy’s $6.0 billion joint revolving credit facility, which can be used for working capital, as support for the combined commercial paper programs of DESC, Dominion Energy, Virginia Power and Questar Gas, and for other general corporate purposes.

At March 31, 2021, DESC's share of commercial paper and letters of credit outstanding under its joint credit facility with Dominion Energy, was as follows:

A maximum of $1.0 billion of the facility is available to DESC, assuming adequate capacity is available after giving effect to uses by co-borrowers Dominion Energy, Virginia Power and Questar Gas. The sub-limit for DESC is set within the facility limit but can be changed at the option of the co-borrowers multiple times per year. At March 31, 2021, the sub-limit for DESC was $500 million. If DESC 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 DESC's parent or 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 $1.0 billion (or the sub-limit, whichever is less) of letters of credit.

In January 2021, DESC and GENCO each 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.

DESC is obligated with respect to an aggregate of $68 million of industrial revenue bonds which are secured by letters of credit. These letters of credit expire, subject to renewal, in the fourth quarter of 2021.

DESC has FERC approval to enter into an inter-company credit agreement with Dominion Energy under which DESC may have short-term borrowings outstanding up to $900 million. At March 31, 2021 and December 31, 2020, DESC had borrowings outstanding under this credit agreement totaling $443 million and $149 million, respectively, which are recorded in affiliated and related party payables in DESC’s Consolidated Balance Sheets. For both the three months ended March 31, 2021 and 2020, DESC recorded interest charges of $2 million.

Fuel Company and GENCO participated in a SCANA utility money pool until January 2021, when that utility money pool was closed. Money pool borrowings and investments bore interest at short-term market rates. For the three months ended March 31, 2021 and 2020 DESC recorded interest income from money pool transactions of less than $1 million and $1 million, respectively, and for the same period DESC recorded interest expense from money pool transactions of less than $1 million and $1 million, respectively. At December 31, 2020, DESC had outstanding money pool borrowings due to an affiliate of $206 million and investments due from an affiliate of $15 million. On its Consolidated Balance Sheet, DESC includes money pool borrowings within affiliated and related party payables and money pool investments within affiliated and related party receivables.
