San Antonio, like Austin, is mostly served by a municipal utility — CPS Energy — and is NOT in the deregulated Texas market. But many surrounding areas (parts of Bexar, Guadalupe, and Comal counties) are in AEP Texas Central territory and DO have plan choice. Check your address first.
If you're in the AEP Central deregulated area around San Antonio, TDU charges run about 4.97¢/kWh plus around $5.94 monthly — same as the Austin suburbs.
The actual electricity rate — the part you can control — is set by your Retail Electric Provider (REP). In San Antonio, the most common providers are Limited — CPS Energy is municipal, suburbs use REPs. Switching providers takes 1-2 billing cycles and doesn't interrupt service.
Inside city limits, you're a CPS customer with no choice. In New Braunfels, Schertz, Boerne, and parts of greater Bexar, you likely have choice.
Even if you can't shop, monitor your CPS rate — it has risen significantly in the past few years and there's talk of further increases.
San Antonio summers are brutal, and your usage spikes 60-80% June through September. A flat rate locked in during spring will save you serious money compared to variable.
The fastest way: use our plan comparison tool with your ZIP code. It pulls every available plan from the Compare Power database (the same data REPs publish to the Public Utility Commission of Texas) and ranks them by what you would actually pay at your usage level.
If you don't know your usage, run the bill calculator first to estimate it, or check your last bill for the "kWh used" number.
Can I switch electricity providers in San Antonio? If you're in a deregulated part of San Antonio, yes — most of San Antonio can switch any time. There's no service interruption.
Does switching providers cost anything? No. Switching itself is free. If you're mid-contract on your current plan, you might owe an Early Termination Fee (typically $150-$295) to your current REP — check your contract.
How long does switching take? Usually 1-2 billing cycles (3-8 weeks). The same poles deliver your electricity throughout; only the billing entity changes.
Will my power get shut off if I switch? No. Switching is paperwork-only. CPS Energy / AEP continues to deliver power without interruption.
