What businesses in San Antonio pay
Across Texas, businesses paid an average 8.57¢ per kWh over the 12 months to August 2026, 38.2% below the U.S. average of 13.87¢, and unchanged on the 12 months before. That ranks Texas 50 of 51, where 1 is the highest price. In 2025 the average commercial account in the state used 9,509 kWh a month, about $814 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 Texas page has the state’s price history since 2010 and every utility with at least 500 commercial customers.
Choosing a supplier in San Antonio
Most Texas commercial accounts inside ERCOT competitive territory choose their retail electric provider while the transmission and distribution utility continues to deliver power and handle outages under regulated tariffs. Municipal utilities such as Austin Energy and CPS Energy, many cooperatives, and non-ERCOT areas including El Paso Electric are not open to choice.
Where prices are heading
EIA does not forecast single states. For the West South Central census division, which includes Texas, its November 2026 Short-Term Energy Outlook puts the average commercial price at 9.15¢ per kWh for 2026 and 9.44¢ for 2027, up 4.9% from 9.00¢ in 2025. The forecast for every region.

Common questions
- Who provides electricity to businesses in San Antonio?
- EIA lists CPS Energy, AEP Texas Central, Pedernales Electric Cooperative and Guadalupe Valley Electric Cooperative and 5 more as electric utilities in Bexar County and Medina 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.
- What is the average commercial electricity rate in San Antonio?
- There is no official figure for a city. EIA publishes prices by state and by utility: CPS Energy averaged 10.09¢ per kWh for its commercial customers in 2025, and Texas averaged 8.57¢ 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.
- Can a business in San Antonio choose its electricity supplier?
- Most Texas commercial accounts inside ERCOT competitive territory choose their retail electric provider while the transmission and distribution utility continues to deliver power and handle outages under regulated tariffs.

The state page for Texas explains how it works and who regulates it.
