Your electricity in zip code 78217 is delivered by CPS Energy. This area is served by a regulated utility.
Residents in zip code 78217 in northeastern San Antonio are served exclusively by CPS Energy, a municipally owned utility operating throughout Bexar County. Unlike much of Texas, San Antonio falls outside the deregulated electricity market, meaning households here cannot choose a competitive retail electricity provider. CPS Energy controls both the generation and delivery of power in this area, setting rates that apply uniformly across the service territory. As of March 2026, the average residential rate in 78217 is approximately 12.1¢/kWh — a figure that reflects CPS Energy's regulated pricing structure. While choice is limited, understanding your rate, usage patterns, and available efficiency programs can still make a meaningful difference on your monthly bill.
The average electricity rate for residential customers in zip code 78217 is approximately 12.1¢/kWh as of March 2026. Because CPS Energy operates as a regulated municipal utility, this rate is set through a public rate-setting process rather than market competition. There are no alternative retail providers offering lower rates in this zip code — the 12.1¢/kWh figure is the standard residential rate that applies to all households in the 78217 area. This rate is generally competitive when compared to statewide averages in Texas, which have fluctuated between 12¢ and 15¢/kWh in recent months depending on the region and provider.
Because 78217 is served by a regulated utility, there are no short-term, medium-term, or long-term electricity contracts to evaluate. CPS Energy customers are automatically on the standard residential tariff. There is no need to shop for contract lengths or worry about early termination fees. Your rate is set by the utility and adjusted periodically through the regulatory process — not by market forces. This removes the complexity of contract shopping but also eliminates the opportunity to lock in a favorable rate during low-price periods.
Zip code 78217 is a non-deregulated zone. CPS Energy is the sole electricity provider serving this area, and no competitive retail electric providers (REPs) such as Reliant, TXU Energy, Green Mountain Energy, or Gexa Energy operate here. This stands in contrast to deregulated Texas cities like Houston, Dallas, or Corpus Christi, where dozens of providers compete for customers. San Antonio's municipal utility model prioritizes rate stability and local governance over open-market competition.
CPS Energy serves the entire city of San Antonio and surrounding Bexar County, making it one of the largest municipally owned utilities in the United States.

Neighboring zip codes in San Antonio — including 78201, 78202, 78204, 78205, and 78207 — are all served by CPS Energy under the same regulated rate structure. Residents across these zip codes pay the same base rate of approximately 12.1¢/kWh, as CPS Energy does not differentiate pricing by neighborhood or zip code. Seasonal demand does influence overall system costs — summer months in San Antonio bring intense heat and peak air conditioning loads, which can drive up usage-based charges. March 2026 represents a transitional period before peak summer demand, making it a good time to audit home energy efficiency and enroll in CPS Energy demand-response or budget billing programs.
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.
