Electricity in San Antonio: why you can't shop around
No. San Antonio is served by CPS Energy, a city-owned utility that hasn't opted into Texas retail competition, so residents can't pick a different electricity provider. Your rates are set locally. Some suburbs nearby are served by other utilities, so if you're outside the city, check your address on Power to Choose.
Power to Choose is the state's official, free plan-comparison site run by the PUCT. We don't get paid when you click.
What that means for your bill
CPS Energy sets the price for the customers it serves. Shopping for a retail plan is not an option at a typical in-city address.
Power to Choose returned no retail plans for ZIPs 78205 and 78201 on October 12, 2026. ERCOT's November 2025 retail market overview names San Antonio as a non-opt-in area.
If you are outside the city
Some nearby addresses are served by other utilities. Don't guess from the city name. Check the service address on Power to Choose.

Questions
Why isn't San Antonio deregulated?
CPS Energy is a city-owned utility. Municipal utilities can opt into Texas retail choice, and most have not. ERCOT's November 2025 retail market overview names San Antonio as an area where customers do not choose a retail provider: https://www.ercot.com/files/docs/2025/11/17/ERCOT-Grid-Insights-Retail-Market.pdf
Could that change?
Yes. A city-owned utility can opt in later if its governing body adopts a resolution. The PUCT explains that right here: https://www.puc.texas.gov/consumer-help/faq/muni/
Who do I call about my bill?
Call CPS Energy. There is no separate retail provider to shop. Account, billing, and outage questions go to the city utility: https://www.cpsenergy.com
Can I go solar or pick green power?
Any solar or green-power option has to come from CPS Energy or from a program it publishes. We are not describing a specific offer. Start on the utility's site: https://www.cpsenergy.com
Which nearby areas can choose?
Some addresses just outside the city utility may be served by a different company. We have not published a reviewed page for those suburbs. Check the address on Power to Choose before you assume you can shop.
