South Carolina Public Service Authority electricity rates

It serves 185,529 residential customers in South Carolina. At 11.38¢ per kilowatt-hour it is one of the cheaper places to buy electricity in South Carolina, 29.7% under the statewide average of 16.18¢.

Consumption is close to the national norm at 945 kilowatt-hours a month against 871, so the rate translates fairly directly into the bill.

Operated by the state itself, with rates set through a public body rather than a commission proceeding. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

In 2024 the average South Carolina Public Service Authority customer went 58 minutes without electricity across 0.69 interruptions. The median across the 941 utilities that report this is 185 minutes.

That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.

South Carolina Public Service Authority offers time-of-use pricing to residential customers. 65 households were enrolled, about 0.1% of its residential base.

These plans are opt-in almost everywhere. They reward households that can move laundry, dishwashing, water heating or electric vehicle charging out of the late-afternoon peak, and they cost more than the standard rate for households that cannot. How to tell which group you are in.

Adoption is above the national median, which generally tracks the retail rate more closely than it tracks sunshine. What exports are actually worth.
