Before you pick a plan, read this.
CPS Energy (municipal) / AEP Texas (surrounding)
Inside the San Antonio city limits you're on CPS Energy, a municipal utility that's not deregulated — no shopping. Outside the city, on AEP Texas territory, you can pick from every retail plan in Texas. Voltcheckr will tell you which side you're on.
What San Antonio residents actually ask before they switch.
Part of San Antonio is in a municipal utility (no shopping), and part is deregulated. Check your ZIP code — Voltcheckr tells you for free which side you're on in 10 seconds.
San Antonio homes average around 1,240 kWh per month at an effective rate near 13.9¢/kWh, which works out to about $172/month. Voltcheckr calculates your exact bill against 200+ plans so you know where you actually stand.
Pick a plan on Voltcheckr, click Switch, and your new provider handles the cancellation of your old plan automatically. No calls, no paperwork, no double billing. Your new rate typically starts within 1–3 business days.
If you're inside a fixed-term contract, early termination fees (ETF) typically run $150–$295. Voltcheckr surfaces the ETF on your current plan and subtracts it from your first-year savings so you see the real break-even. If you're in the last 14 days of your contract, you can switch ETF-free.
Rates change daily. Upload your bill (or enter your ZIP + home size) and Voltcheckr shows you the real-time cheapest plan, with live rates from Texas electricity suppliers.
