Dominion Energy South Carolina covers most of the cities we've sampled — Columbia, Charleston, North Charleston, Mount Pleasant and Summerville all run on it. Rock Hill, near the North Carolina line, is the exception: it runs its own municipal electric utility. South Carolina has no retail electric market, so the utility holding your address is simply yours.

Dominion Energy South Carolina (formerly SCE&G) delivered electricity at sampled addresses across Columbia, Charleston, North Charleston, Mount Pleasant and Summerville — most of the state's population centers we've checked. Rock Hill, up near Charlotte and the North Carolina border, is the exception: it runs its own city-owned electric utility rather than buying from Dominion.
South Carolina doesn't run a retail electricity market, so there's no supplier to shop for — whichever utility holds your address delivers the power directly. Along the coast, Charleston and North Charleston share the same water provider, the Charleston Water System, which simplifies that account for the Lowcountry cities; elsewhere, water coverage isn't consistently confident yet in our sampling.

Rock Hill operates its own city-owned electric utility rather than buying power from Dominion Energy South Carolina — a genuine exception to the pattern that covers most of the rest of the state's population centers in our sampling.
Yes — both cities draw from the Charleston Water System in our sampled data, which is unusual consistency for a service that's normally split city by city. Confirm with the lookup for your exact address, since coverage can still shift near city lines.
No — South Carolina doesn't run a deregulated electricity market. Whichever utility holds your address, Dominion Energy South Carolina or Rock Hill's municipal utility, is who you sign up with directly, with no competing supplier to shop for.
