Properties, in its own words

DESC has approximately 3,800 miles and 19,400 miles of electric transmission and distribution lines, respectively, exclusive of service level lines, in South Carolina. The grants for most of DESC’s electric lines contain rights-of-way that have been obtained from the apparent owners of real estate, but underlying property titles have not been examined. Where rights-of-way have not been obtained, they could be acquired from private owners by condemnation, if necessary. Many electric lines are on publicly-owned property, where permission to operate can be revoked. In addition, DESC owns 454 substations.

DESC’s natural gas system includes approximately 20,000 miles of distribution mains and related service facilities, which are supported by approximately 400 miles of transmission pipeline.

The rest of Item 2

DESC owns two LNG facilities, one located near Charleston, South Carolina, and the other in Salley, South Carolina. The Charleston facility can store the liquefied equivalent of approximately 1.0 bcf of natural gas, can regasify approximately 6% of its storage capacity per day and can liquefy less than 1% of its storage capacity per day. The Salley facility can store the liquefied equivalent of approximately 0.9 bcf of natural gas and can regasify approximately 10% of its storage capacity per day. The Salley facility has no liquefying capabilities.

DESC’s bond indenture, which secures its first mortgage bonds, constitutes a direct mortgage lien on substantially all of its electric utility property.

  • DESC has been and may continue to be or become subject to legal proceedings and governmental investigations and examinations.
  • Environmental Risks

  • Compliance with federal and/or state requirements imposing limitations on GHG emissions or efficiency improvements, as well as Dominion Energy’s commitment to achieve net zero carbon and methane emissions by 2050, may result in significant compliance costs, could result in certain of DESC’s electric generation units or natural gas facilities being uneconomical to maintain or operate and may depend upon technological advancements which may be beyond DESC’s control.
  • DESC is subject to risks associated with the disposal and storage of coal ash.
  • Construction Risks
  • DESC’s infrastructure build and expansion plans often require regulatory approval, including environmental permits, before commencing construction and completing projects.

  • Operational Risks
  • DESC’s financial performance and condition can be affected by changes in the weather, including the effects of global climate change.

  • Changing rating agency requirements could negatively affect DESC’s growth and business strategy.
  • An inability to obtain needed capital or financing on satisfactory terms, or at all, could have an adverse effect on DESC’s operations and ability to generate cash flow.

  • The use of derivative instruments could result in financial losses and liquidity constraints.
  • Exposure to counterparty performance may adversely affect DESC’s financial results of operations.
  • Public health crises and epidemics or pandemics could adversely affect DESC’s business, results of operations, financial condition, liquidity and/or cash flows.

Legal proceedings

From time to time, DESC is party to various legal, environmental or other regulatory proceedings, including in the ordinary course of business. SEC regulations require disclosure of certain environmental matters when a governmental authority is a party to the proceedings and such proceedings involve potential monetary sanctions that DESC reasonably believes will exceed a specified threshold. Pursuant to the SEC regulations, DESC uses a threshold of $1 million for such proceedings.
