Site description

Dominion Energy Company’s Williams Generating Station is located in Berkeley County, SC, in the floodplain between the Back and Cooper Rivers. Williams Generating Station began operations in 1973 and now operates a single, 633 MW coal-fired unit. This station operates both an onsite FGD pond and an offsite Ash Landfill located off South Carolina’s Hwy-52. Williams Generating Station currently has no plans to retire their coal-fired units. The FGD Pond and Ash Landfill are regulated under the CCR rule. You can find the industry-reported data here.
