This is a list of electricity-generating power stations in the U.S. state of South Carolina, sorted by type and name. In 2024, South Carolina had a total summer capacity of 24.7 GW through all of its power plants, and a net generation of 100,485 GWh. In 2025, the electrical energy generation mix was 54.1% nuclear, 21.5% natural gas, 17.3% coal, 3.2% solar, 2.4% hydroelectric, 1.5% biomass, and 0.1% petroleum.

South Carolina is the nation's third largest producer of nuclear power, with four nuclear plants. Natural gas has been the most rapidly growing source of generation; quadrupling over the decade starting 2010. Data from the U.S. Energy Information Administration serves as a general reference.
