Before you pick a plan in San Antonio
An advertised rate holds at one usage level. At usage like San Antonio's (1,240 kWh in an average month), base charges, bill-credit thresholds, and minimum-usage fees change what you actually pay, which is why every Texas plan's Electricity Facts Label lists its average price at 500, 1,000, and 2,000 kWh. Each plan's details on our results show the fees and credit terms we receive for it and its prices at those three levels, next to its label.
What each one means, with examples: the rates guide and the glossary.

Energy choice
Does San Antonio have energy choice?
Mostly no. San Antonio proper, in ZIP codes starting with 782, is served by CPS Energy, the largest municipal utility in the country, which has not opted into retail competition. There is no retail choice there: CPS Energy delivers and bills, and no provider switch is possible.
Some surrounding communities sit on deregulated AEP Texas territory and can shop retail plans. Others run their own municipal utilities, which have not opted into retail competition, and cannot: New Braunfels is on New Braunfels Utilities and Boerne has a city utility of its own.
If you are near the edge of the metro, enter your ZIP in the comparison and it will tell you honestly which market you are in, including when the answer is that your area has no retail choice.
