South Carolina Public Service Authority electricity rates
South Carolina Public Service Authority is state serving 185,529 residential customers in South Carolina, at an average residential price of 11.38¢ per kilowatt-hour.
That price is derived, and it is annual. It is total residential revenue divided by total residential sales in EIA’s 2024 survey — not a tariff, and not this month’s rate. For what a kilowatt-hour costs in South Carolina right now, see the state page, currently 15.55¢.
