Recognizing the challenges economic pressures have placed on everyone, Dominion Energy has carefully considered the best way to minimize the impact of rising fuel costs to produce electricity that are beyond our control. Specifically, the cost of natural gas has more than doubled since the last fuel cost adjustment. The company has requested a mid-period adjustment so that our customers see the lowest possible increase to their bills as we recover costs of purchasing and transporting fuel to produce the electricity they rely on every day. These fuel costs are a direct pass-through to customers – Dominion Energy does not earn a profit on this portion of electric rates. We encourage customers to contact us if they need payment assistance. In addition to $250 million still available in state and federal programs, customers can learn more about the $1 million available through EnergyShare, Dominion Energy's year-round assistance program.

A fuel cost adjustment involves coal, natural gas, nuclear, oil, solar, and purchased power costs needed to supply electricity to customers. The Public Service Commission of South Carolina annually reviews the costs Dominion Energy incurs for purchasing and transporting fuel to operate our electric generation facilities. Based on this review, the commission authorizes the company to adjust our electric rates – upward or downward – to reflect those incurred costs without any markup or profit.

If the company's mid-period fuel filing is approved as submitted, the average monthly bill of a residential customer using 1,000 kilowatt hours of electricity would increase by approximately 14%. This means an average residential bill of approximately $133 would increase to approximately $151. If approved, customers would see the increase in bills beginning in January 2023.

The company estimates increases of approximately 17% for commercial customers and 27% for industrial customers.

Dominion Energy maintains a diverse portfolio of electric generating facilities utilizing many different fuel sources, including natural gas, coal, nuclear, solar and oil. Significant and unforeseen market changes – namely higher commodity prices and increased demand for those commodities – have affected the prices of these fuel sources since our annual fuel cost adjustment, which was approved in April.

On Aug. 8, Dominion Energy South Carolina filed for a mid-period fuel cost adjustment. We respectfully requested that the commission schedule a hearing at the earliest possible time with appropriate notice to customers and the public. The commission will hear requests from the company and other parties on Nov. 29 at 10 a.m. and will continue as the commission determines necessary. The proceedings will be streamed live. Customers can participate by intervening or appearing at public hearings on Nov. 28 from 9 a.m.-1 p.m. or 4-8 p.m. For more details, please see the Notice of Filing and Public Hearings or contact the commission at 803-896-5100 or

Currently, approximately 25% of what a residential customer pays for a kilowatt hour of electricity represents the costs of fuel to run Dominion Energy South Carolina's power plants. If the adjustment is approved as submitted, fuel costs would become 34% of the average residential 1,000 kilowatt-hour bill.

As of June 30, 2022, Dominion Energy has under-collected approximately $202 million in fuel costs. If we do not request a mid-point fuel cost adjustment, the under-collected balance is estimated to increase to approximately $404 million by October 2022, and to approximately $592 million by April 2023. In other words, actual costs are significantly higher than what Dominion Energy has been charging customers based on earlier fuel cost projections determined by market conditions at the time, and this will continue to increase substantially. For example, if the under-collection issue is not addressed in part now, we estimate our residential customers would likely experience a significant bill increase in May 2023 of approximately 27%.

We rely upon natural gas pricing data provided by the New York Mercantile Exchange (NYMEX), which is a financial market that captures real-time trading data about the projected price of natural gas and other commodities.

With a diverse energy portfolio, Dominion Energy can select the most economical generation source available on its system and can also purchase power in the electric markets if it is more economical. However, natural gas short-term prices can fluctuate based on weather conditions, increased customer demand, changes in national supply and global demand, fluctuations in storage inventory levels, geopolitical matters, and other economic factors. The market for coal and fuel oil can be less volatile than the market for natural gas, but both fuel sources are subject to cost fluctuations due to production shortages, overall demand, and increased exports into the international market.

The Public Service Commission of South Carolina held a public hearing April 7-8, 2022, for Dominion Energy's annual fuel cost proceeding. During the proceeding, Dominion Energy requested an adjustment to recover approximately $142 million already spent on fuel costs. The company saw our annual fuel costs rise by nearly 50% when comparing calendar year 2021 to calendar year 2020. On April 28, the commission approved the fuel filing, which resulted in the monthly bill of a residential customer using 1,000 kilowatt hours of electricity increasing by approximately 5.19% – or $6.53 beginning in May. Since then, the cost of fuel to operate our electric generation facilities has continued to increase significantly, exceeding industry cost projections that the company expected would be incurred.
