Who provides electricity to businesses in Round Rock?

EIA lists Oncor Electric Delivery, Austin Energy, Pedernales Electric Cooperative and Bluebonnet Electric Cooperative and 3 more as electric utilities in Williamson County and Travis 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 Round Rock?

There is no official figure for a city. EIA publishes prices by state and by utility: Oncor Electric Delivery averaged 3.90¢ per kWh for its commercial customers in 2025, for delivery alone, 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.

What businesses in Round Rock 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 Round Rock

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.
