South Carolina Electricity Information

South Carolina’s electricity generation is led by nuclear power, which provides the majority of the state’s energy and helps keep emissions lower than in states reliant on fossil fuels. Natural gas has grown significantly, while coal use has declined, further reducing the state’s carbon footprint. Hydroelectric and solar power also contribute, with solar expanding rapidly in recent years. Electricity prices in South Carolina are close to the national average, though high summer demand for air conditioning can drive up costs for consumers.

With its strong nuclear and growing renewable energy sector, South Carolina is making progress toward a cleaner energy future. However, as natural gas remains a major player, the state continues to balance affordability, reliability, and sustainability in its power generation.
