Dominion Energy South Carolina Inc., a wholly owned subsidiary of Dominion Energy Inc., submitted comprehensive settlement agreements May 8 in its pending general electric rate case with South Carolina regulators.

Intervening parties have engaged with Dominion Energy South Carolina for several months to reach the settlement agreements. They include the South Carolina Office of Regulatory Staff, the South Carolina Department of Consumer Affairs, the South Carolina Energy Users Committee, the Southern Alliance for Clean Energy, the South Carolina Coastal Conservation League, the Sierra Club, CMC Steel South Carolina, Walmart, and AARP, among others.

Dominion Energy South Carolina and the intervening parties will present the settlements to the PSC at a hearing scheduled to begin May 12.

The utility submitted its settlement agreements for approval by the Public Service Commission of South Carolina (PSC). With the exception of one party, the settlements include all parties signing, supporting, or not opposing, according to Dominion.

The company said that since 2023, it has added roughly 23,000 new electric customers to its system, in which it has invested $1.4 billion to keep it running reliably and cost-effectively. If approved by the PSC, the proposed settlements would allow the company to recover the rising costs of its investments.

Additionally, a PSC approval would increase the average monthly bill for a residential customer using 1,000 kilowatt-hours by about $12 starting July 1.

The approved settlements also would include a total of $6 million funded by shareholders that would directly assist customers, and would consist of a one-time $3 million refund in the form of a bill credit applied this year for residential customers.

Also, an additional $1 million annually for three years would help low-income customers through payment assistance programs and support weatherization projects if the settlements are approved.

At the same time, the proposed settlements also support an authorized return on equity of 9.99 percent; a regulatory capital structure equity component of 53.52 percent; and a revenue increase of $207 million, which is about 36 percent less than the original request of $322 million in January, the utility said.
