Your electricity in zip code 78225 is delivered by CPS Energy. This area is served by a regulated utility.
Residents of zip code 78225 in San Antonio, Bexar County receive their electricity exclusively through CPS Energy, a municipally owned utility serving the greater San Antonio metro area — home to over 1.4 million people. Unlike deregulated parts of Texas where consumers shop among competing retail providers, 78225 operates under a regulated municipal utility model, meaning CPS Energy sets and delivers electricity at a single, standardized rate. As of March 2026, the average residential rate in this area is approximately 12.1¢/kWh. While provider choice isn't available here, understanding your rate structure, billing options, and efficiency programs can still make a meaningful difference in what you pay each month.
The current average residential electricity rate in San Antonio's 78225 zip code is 12.1¢/kWh, as set by CPS Energy. This rate is applied uniformly across the service territory — there is no rate shopping available to residents in this zip code. Compared to the statewide deregulated market average, which can fluctuate significantly based on provider competition and contract terms, CPS Energy's regulated rate tends to offer more predictability month to month. Your total bill will depend on consumption, applicable fees, and any demand charges for higher usage tiers.
Because 78225 is served by a regulated municipal utility, residents do not have access to the competitive fixed-rate or variable-rate contracts available in deregulated Texas markets. CPS Energy sets its own rate schedules, which are reviewed and adjusted periodically through a public regulatory process. However, CPS Energy does offer budget billing and prepaid programs that can help smooth out seasonal bill spikes — particularly useful during San Antonio's hot summers when cooling costs surge.
Unlike neighboring deregulated regions of Texas where dozens of retail electric providers (REPs) compete for customers, 78225 has no retail electricity competition. CPS Energy is the sole provider. This means residents cannot switch to providers like Reliant, TXU Energy, Gexa Energy, Green Mountain Energy, or Pulse Power — all of which operate in deregulated Texas territories. While this limits rate-shopping flexibility, it also means residents are insulated from the kind of extreme price volatility that deregulated market customers can face during peak demand events.

Rate changes must go through a public approval process, giving ratepayers a degree of transparency and input not always available in competitive markets.
