Cibolo, Texas (zip code 78604) sits in Guadalupe County — one of the fastest-growing communities in the greater San Antonio region, with a population of over 32,000 residents. Unlike some Texas markets, 78604 falls within the AEP Texas Central (AEP-Central) service territory, a fully deregulated zone where residents have real power to choose their electricity provider. As of March 2026, 18 retail electric providers are actively competing for customers here, offering 82 distinct plans — including 73 fixed-rate options and 6 green/renewable plans. That level of competition is genuinely good news for households: it keeps pricing aggressive and gives consumers meaningful choices between contract lengths, green energy options, and billing structures.
The most competitive rate available in zip code 78604 right now is 9.5¢/kWh, offered through True Power's AEPTCC 12-month Fixed Residential plan. That's a meaningful 25% below the area's average rate of 12.7¢/kWh across all 82 available plans. The full rate range in this market spans from 9.5¢ at the competitive end up to significantly higher rates on short-term or variable plans — which is why plan selection matters enormously. For a typical Cibolo household using 1,000–1,500 kWh per month, choosing the best available rate over the average could save $30–$50 or more every month.
