Site description

South Carolina Public Service Authority’s Winyah Generating Station is located in Georgetown County, SC, along the banks of the Winyah Bay, close in proximity to the Atlantic Ocean. Winyah Generating Station began operations in 1975 and now operates four coal-fired units capable of producing 1,155 MW. This station also operates four onsite CCR disposal ponds as well as an onsite man-made cooling water pond. As of February 2019, South Carolina’s electric cooperatives have requested that Santee Cooper investigate whether or not coal combustion is still the cheapest method of producing electricity. Winyah Generating Station’s South Ash Pond, Ash Pond A, Ash Pond B and Slurry Ponds are regulated under the CCR rule. You can find the industry-reported data here. For more information on Winyah Generating Station, see EIP’s 2019 National Coal Ash Report.
