City of San Antonio electricity rates

It serves 865,914 residential customers, making it one of the larger utilities in Texas. At 12.43¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Texas, 24.4% under the statewide average of 16.44¢.

Its customers use more electricity than the national norm, 1,070 kilowatt-hours a month against 871, which amplifies whatever the rate does.

Owned by the city it serves and governed by a local board rather than the state commission. No shareholder return is built into the rate. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

In 2024 the average City of San Antonio customer went 74 minutes without electricity across 1.15 interruptions. The median across the 941 utilities that report this is 185 minutes.

That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.

46,442 residential customers had net-metered solar in 2024, totalling 393.38 megawatts. That works out to 53.6 installations per thousand customers, against a median of 8 across the utilities reporting it.

Adoption here is exceptionally high. That usually means some combination of a high retail rate worth displacing, strong sunshine and favourable export rules, and it tends to bring its own regulatory argument about who covers the fixed cost of the network. What exports are actually worth.
