Key Takeaways

Rock Hill Electricity Prices

Have you noticed your Rock Hill electricity bill creeping higher each year? You’re not alone, and the numbers tell the story.

South Carolina’s electricity prices rose from 12.9 cents per kWh in 2021 to 14.1 cents in 2024, a 9.3% increase. For Rock Hill homeowners served by Duke Energy or York Electric Cooperative, those steady jumps add up over time.

Rock Hill Area Utility Providers

If you live in Rock Hill, your electricity likely comes from Duke Energy. In 2023, Duke Energy charged about 12.7¢ per kWh—below both the South Carolina average of 13.70¢ and the national average of 16.0¢.

Duke Energy’s rates stay below national averages partly because of the region’s energy mix and lower demand costs. Even so, South Carolina rates run slightly above Duke’s Rock Hill pricing, and utility costs tend to rise over time.
