Electricity in South Carolina: price, usage, and the average bill
The average price — 14.23¢ per kWh in 2024 — is EIA's blended figure: total residential electricity revenue in South Carolina divided by total residential sales, across every utility and every home in the state. It blends fixed customer charges into the per-kWh number, so it will never match the energy rate printed on any single tariff. The latest monthly snapshot, July 2026 (preliminary), puts the average price at 15.47¢ per kWh; July is a summer month, so read it as a snapshot, not a new annual rate.
Usage is the other half of the bill: at 1,050 kWh a month, South Carolina usage runs 22% above the U.S. average of 863 kWh. Price times usage is why the average bill lands at $149.51 — read the two together, never the price alone. Our electricity guide puts all 50 states side by side.
Natural gas in South Carolina
Natural gas delivered to South Carolina homes cost an average of $16.91 per thousand cubic feet (Mcf) in 2024 — 17% above the U.S. average of $14.50. "Delivered" means the full price at the meter: the gas itself plus transportation and the local distribution company's charges. On the unit your bill most likely uses, that is about $1.63 per therm (1 Mcf ≈ 10.37 therms). We publish the price but not an "average gas bill" for South Carolina: the annual price table carries no per-state household consumption figure we can stand behind, so the honest way to size a gas bill is your own therms in the calculator. The natural gas guide covers all 50 states.
Heating and cooling: where the money goes in South Carolina
South Carolina households are among the country's heavier electricity users — 1,050 kWh a month against a 863-kWh national average. That is the pattern EIA data shows across the hot, humid South and Gulf states: air conditioning runs for much of the year, and in many homes electric heat and electric water heating add to the load in winter too. The result is that even a below-average price per kWh can still produce an above-average bill — volume, not price, is what drives the South Carolina total.
Heating oil and propane in South Carolina
EIA does not publish residential heating-oil or propane prices for South Carolina: its weekly survey covers the states where those delivered fuels are a common way to heat a home, and South Carolina is not on either survey list. That is a gap in the federal data, not a zero — homes in South Carolina do burn both fuels, but no official state average exists to print, so we don't estimate one. The published fuels for South Carolina are electricity and piped natural gas, above.
Before you compare your bill
- Averages blend every home size and every utility in the state — a small apartment and a large detached house are in the same average.
- Annual averages hide the seasons. A July bill in a cooling climate and a January bill in a heating climate can each be double the annual average month.
- The average price is not a tariff. Your utility's actual rate schedule — including its fixed monthly customer charge — is the number that prices your bill; the EIA average is the benchmark to compare it against.
