What businesses in North Charleston pay
Across South Carolina, businesses paid an average 11.68¢ per kWh over the 12 months to August 2026, 15.8% below the U.S. average of 13.87¢, and up 5.5% on the 12 months before. That ranks South Carolina 31 of 51, where 1 is the highest price. In 2025 the average commercial account in the state used 5,389 kWh a month, about $602 a month at the state price; that is a mean pulled up by a few very large users, so most small businesses use less.
A city has no price of its own: two businesses on the same street can pay very different amounts per kWh, because the rate schedule, the size of the peak and, where it is allowed, the supply contract matter more than the location. The South Carolina page has the state’s price history since 2010 and every utility with at least 500 commercial customers.
