What businesses in Louisville pay
Across Kentucky, businesses paid an average 12.37¢ per kWh over the 12 months to August 2026, 10.8% below the U.S. average of 13.87¢, and up 5.9% on the 12 months before. That ranks Kentucky 27 of 51, where 1 is the highest price. In 2025 the average commercial account in the state used 5,273 kWh a month, about $620 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 Kentucky page has the state’s price history since 2010 and every utility with at least 500 commercial customers.

Common questions
- Who provides electricity to businesses in Louisville?
- EIA lists LG&E, Salt River Electric Coop Corp and Shelby Energy Coop, Inc as electric utilities in Jefferson County. Which one serves a given address depends on the street; the utility on an existing bill is the definitive answer, and a utility can confirm service for a new site.

EIA publishes prices by state and by utility: LG&E averaged 11.46¢ per kWh for its commercial customers in 2025, and Kentucky averaged 12.37¢ over the 12 months to August 2026. A business’s own price depends on its rate schedule, its demand and, where it can choose, its supply contract.
