Your electricity in zip code 78252 is delivered by CPS Energy. This area is served by a regulated utility.
Residents of zip code 78252 in San Antonio, Bexar County, receive their electricity exclusively through CPS Energy — a municipally owned utility serving the greater San Antonio area. Unlike much of Texas, this zip code is not part of the deregulated ERCOT retail market, meaning residents cannot choose an alternative retail electricity provider. As of March 2026, CPS Energy's average rate in this area is approximately 12.1¢/kWh. While competition among retail providers isn't a factor here, understanding your utility's rate structure, available programs, and energy efficiency options can still make a meaningful difference in your monthly bill. San Antonio is home to over 1.4 million residents, and CPS Energy serves the vast majority of them under a regulated, city-governed framework.
As of March 2026, the average electricity rate for CPS Energy customers in the 78252 zip code is 12.1¢/kWh. Because CPS Energy is a regulated municipal utility — not a competitive retail market — this rate is set by the utility and approved through a city-governed process, not determined by market competition. There is no rate range across providers to compare, but CPS Energy does offer tiered rate structures and time-of-use (TOU) options that can affect what individual customers ultimately pay based on their consumption habits.
For context, the statewide average in deregulated Texas markets often runs between 11¢ and 16¢/kWh depending on contract type and provider, meaning CPS Energy's 12.1¢/kWh average is reasonably competitive for a fixed municipal rate — particularly when you factor in the stability it provides without contract lock-ins or variable rate risk.
Because 78252 is served by a regulated utility, traditional short-term vs. long-term contract comparisons don't apply. CPS Energy customers are not locked into retail contracts. Instead, your rate is determined by the utility's approved tariff. However, CPS Energy does offer optional programs — including budget billing (which averages your annual costs into equal monthly payments) and time-of-use rate plans — that can function similarly to choosing a plan type in a deregulated market. Customers with flexible schedules who can shift heavy usage (laundry, dishwashing, EV charging) to off-peak hours may see meaningful savings under a TOU arrangement.
Zip code 78252 is not part of Texas's deregulated electricity market. There are no competing retail electricity providers (REPs) serving this area. CPS Energy is the sole electricity provider for residential and commercial customers in San Antonio's service territory. This is distinct from cities like Houston, Dallas, or Austin (outside city limits), where dozens of providers compete for customers.
CPS Energy is a municipally owned utility governed by the City of San Antonio. It handles both electricity generation/procurement and delivery infrastructure (poles, wires, meters) for the 78252 area. Because there is no separation between the retail and delivery functions — as there is in deregulated TDSP territories — there are no separate delivery charges to compare across providers. Your entire electricity bill comes from CPS Energy directly. To enroll in efficiency programs, rate plan options, or payment assistance, customers should contact CPS Energy directly at cpsenergy.com or call their customer service line.
Neighboring zip codes including 78201, 78202, 78204, 78205, and 78207 are all similarly served by CPS Energy under the same municipal utility framework. Rates and program availability are consistent across San Antonio's CPS service territory. Seasonal demand peaks — particularly during July and August when temperatures regularly exceed 100°F — can strain the grid and drive higher usage bills, even though the per-kWh rate itself remains stable. Spring months like March are typically the most cost-effective time for San Antonio residents to assess their energy usage before summer demand surges.
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.
