List of power stations in South Carolina explained

This is a list of electricity-generating power stations in the U.S. state of South Carolina, sorted by type and name. In 2022, South Carolina had a total summer capacity of 24,286 MW through all of its power plants, and a net generation of 98,709 GWh.^[1] In 2023, the electrical energy generation mix was 54.6% nuclear, 23.8% natural gas, 14.9% coal, 2.7% solar, 2% hydroelectric, 1.9% 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.^[2] Data from the U.S. Energy Information Administration serves as a general reference.

Units 2 and 3 were originally planned to be converted to natural gas as an interim step to closure, but those plans were abandoned.^{[13] [14]}
Fueled by mix of coal and natural gas
Units 3 and 4 are permitted to fire up to 30% petcoke by weight on either boiler.
