Site description

Dominion Energy Company’s Williams Generating Station is in Goose Creek, South Carolina in the floodplain between the Back and Cooper Rivers in Berkeley County. It operates a single 660-MW coal-fired unit. Williams Generating Station began operations in 1973 and is planned for retirement in 2028. 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.
