Important: Electricity plan availability in San Antonio depends on your specific address.
San Antonio is partially deregulated. Most addresses within the San Antonio city limits are served by CPS Energy, a municipal utility — meaning you cannot choose your electricity provider. However, some addresses in the greater San Antonio metro area fall within AEP Texas Central's service territory, where the market is fully deregulated and you can shop for competitive rates.
Enter your ZIP code above to check whether competitive plans are available at your address. If you're in CPS Energy's territory, WattKarma cannot offer alternative plans — but we can still help you understand your current rate.
Parts of the San Antonio metro area fall within AEP Texas Central's service territory, where the electricity market is fully deregulated and you can choose your own supplier.

Texas Electricity Facts Labels must publish an average price at these three checkpoints. We do not invent sample competitor cents — those numbers go stale the day they are typed.
