About electricity rates in South Carolina
South Carolina's electricity comes from regulated, vertically integrated utilities and there is no retail choice. Dominion Energy South Carolina and two Duke Energy companies serve most urban customers, while Santee Cooper, a state-owned utility, supplies the electric cooperatives that serve much of the rural state. The South Carolina Public Service Commission sets rates for the investor-owned utilities.
Nuclear plants provide the largest share of generation, with natural gas increasingly replacing coal and solar farms adding to the mix. Hot, humid summers drive heavy air-conditioning use, and because electric heat pumps are the norm, cold snaps also produce high winter peaks. Net metering is available for rooftop solar.
