Dominion Energy South Carolina requests regulatory review of electric rates to maintain safe, reliable, efficient service as customer growth continues

March 4, 2024
  • Requested increase to base rates is first in nearly four years
  • Rates are lower than national average

Since 2019, Dominion Energy South Carolina has added approximately 40,000 new electric customers to its system and invested $1.6 billion in its electric system to provide reliable, affordable and increasingly clean energy to power our customers every day. Compared to today’s rates and offset by a proposed fuel cost reduction and other factors, the company’s rate request filed today with the Public Service Commission of South Carolina would result in a net 3.58 percent increase for a residential customer’s electric rates.

If approved as requested, the bill of a typical residential customer using 1,000 kilowatt-hours of electricity per month would be approximately $151. This would be an average monthly increase of about $5 from today’s bill. It is expected that the commission will conduct a series of public hearings during the summer. If approved, new rates would be effective in September.

“Our dedicated men and women work hard to keep the lights on for our customers no matter the conditions,” said Keller Kissam, president of Dominion Energy South Carolina. “As a responsible energy company, this means we must invest money needed to keep our plants running, to keep our system reliable and to keep our grid secure – all while doing our part to help make South Carolina a place where people want to raise their families and run their businesses.”

Investments in technology and infrastructure, including year-round enhancements to the electric transmission and distribution systems, are necessary to meet the growing need for energy in South Carolina as well as increasingly strict safety, reliability and security standards. These investments include:

  • $963 million in installation of more than 19,000 distribution transformers, nearly 1,600 miles of distribution lines as well as new or replacement transmission lines, switchyards and substations, including two solar substations.
  • $478 million in upgrades, improvements, and additional environmental controls for generation plants.
  • $135 million in technology, systems and equipment to better serve customers and enhance system security.

Other reasonable and necessary costs include those for storm response and restoration, vegetation management and environmental remediation.

“If approved by the commission, Dominion Energy’s diligent management of electric fuel costs will help keep this proposed rate adjustment as low as it is,” Kissam said. “We’re committed to running our business efficiently and reliably as we continue to integrate increasingly clean energy while maintaining affordable rates.”
