Your electricity in zip code 78245 is delivered by CPS Energy. This area is served by a regulated utility.
If you live in the 78245 zip code on San Antonio's west side, your electricity is provided by CPS Energy — a municipally owned utility that serves the greater San Antonio area within Bexar County. Unlike most of Texas, this area is not part of the deregulated electricity market, meaning residents cannot shop among competing retail electricity providers. CPS Energy controls both the generation and delivery of power to your home. As of March 2026, the average rate in this area is approximately 12.1¢/kWh. While you can't switch providers, understanding how CPS Energy structures its rates — and how to reduce your consumption — can still make a meaningful difference on your monthly bill in a city of over 1.4 million people.
Residents of the 78245 zip code in San Antonio pay an average rate of 12.1¢/kWh through CPS Energy as of March 2026. This rate reflects a bundled structure that includes both energy supply and delivery costs, since CPS Energy operates as a vertically integrated municipal utility rather than separating generation from wires and poles. Bexar County households with a median income of $55,084 feel the impact of electricity costs acutely during peak summer months, when usage can spike significantly. The 12.1¢/kWh average is competitive by Texas standards, particularly when compared to deregulated markets where retail rates can range from 11¢ to over 16¢/kWh depending on contract type and provider.
Because 78245 is served by a regulated municipal utility, there are no short-term, medium-term, or long-term electricity contracts to compare — CPS Energy sets a single tariff rate for residential customers. However, CPS Energy does offer time-of-use (TOU) rate programs that reward customers who shift energy consumption to off-peak hours. If your household has flexibility in when you run appliances, a TOU plan could meaningfully reduce your effective rate below the 12.1¢/kWh average. Enrolling in these programs is done directly through CPS Energy's customer portal or by calling their customer service line.
Unlike neighboring areas in deregulated Texas zones — where providers like Reliant, TXU Energy, Green Mountain Energy, Gexa Energy, and Rhythm Energy compete for your business — the 78245 zip code has no retail electricity competition. CPS Energy is the sole provider, authorized by the City of San Antonio. This means pricing is set through a public rate-review process rather than market forces, which provides stability but limits consumer choice.
CPS Energy serves the entire San Antonio metro area, including 78245 and neighboring zips such as 78201, 78202, 78204, 78205, and 78207. As a municipal utility, CPS Energy is not part of ERCOT's competitive retail market. There is no TDSP separation here — CPS Energy handles generation, transmission, and distribution under one roof. Switching providers is not an option, and enrollment with a third-party retailer is not available in this territory.
Compared to deregulated San Antonio-adjacent areas or cities like Houston and Dallas where consumers shop for rates, 78245 residents trade choice for consistency. Spring months like March typically bring moderate electricity bills before summer heat drives air conditioning demand — and bills — sharply higher. Planning efficiency upgrades now, before peak season, is one of the most effective strategies available to CPS Energy customers.
Enroll in CPS Energy's Residential Time-of-Use rate plan and shift high-energy tasks — laundry, dishwashing, EV charging — to after 8 PM or before 3 PM on weekdays to avoid peak-hour surcharges during San Antonio's intense summer afternoons.
Apply for CPS Energy's free home energy audit program, which dispatches a certified technician to identify air sealing and insulation gaps common in older San Antonio homes, particularly those built before 1990 in neighborhoods like Southtown or Lavaca.
Install a programmable or smart thermostat and set it to 78°F or higher when away from home — in San Antonio's 100°F+ summer heat, every degree of setback can reduce cooling costs by approximately 3–4% per month.
Check eligibility for the CPS Energy REAP (Residential Energy Assistance Program) if your household income falls within federal guidelines — qualifying customers can receive direct bill credits and free weatherization upgrades that meaningfully reduce year-round energy expenses.
