CPS Energy rates, bills and the 2026 rise

The average price, by period

CPS Energy is a municipal utility: EIA lists it under its legal owner, the City of San Antonio (CPS Energy). It sells and delivers electricity to 888,946 homes, 6.9%¹ of the residential customers in Texas. Three figures answer the "rate per kWh" question, and each covers a different period:

Each price is average revenue per kWh: what CPS Energy billed its residential customers, divided by the kWh they used. It folds in the fixed monthly charge, fuel recovery and seasonal differences, so it will not match any single line of a rate schedule, and a small user pays more per kWh than a heavy one. The August 2026³ figure is a summer month and preliminary; the 12-month average is the steadier guide.

On the 2025 figure, CPS Energy ranked tied for 15th lowest of the 61 Texas utilities with 10,000 or more residential customers and 19.5% below the Texas average for all providers. Against the country it was 20th lowest of 177 large US utilities and 14.4% below the national average for public power¹.

Flat in 2025, higher in 2026

Between 2024 and 2025 almost nothing moved. The residential average went from 12.43¢ per kWh to 12.40¢ per kWh (−0.2%), use per home from 1,070 kWh to 1,075 kWh a month, and the average bill from $133.09⁴ to $133.34 (+0.2%¹). From 2024 to 2025 the Texas residential average, all providers, rose 3.1%⁵.

The monthly survey shows the change since then. The 12 months to August 2026 averaged 12.81¢ per kWh, above the 2025 figure, and August 2026³ came in +4.7%² on August 2025. The chart shows each month against the same month of the year before, the comparison that keeps the summer peak from distorting the change.

EIA reports what customers paid, not the decisions behind it, so the data cannot say how much of the rise comes from base rates and how much from fuel and other pass-through charges. CPS Energy's own rate pages list current charges and any pending changes.

One utility for every home on its wires

Most Texans buy electricity from a retail electric provider: 55.5% of the state's residential customers did in 2025. CPS Energy's customers do not. EIA counts every one of its 888,946¹ residential customers as full-service, buying both the electricity and its delivery from the utility, so the averages above cover all homes it serves.

That makes San Antonio part of the other Texas market, the cooperatives, city utilities and investor-owned utilities that still sell power themselves. Side by side, for 2025:

• CPS Energy residential customers: 12.40¢ per kWh.
• All Texas residential customers outside the competitive market: 13.11¢ per kWh.
• Texas residential customers of retail electric providers: 17.23¢ per kWh¹, a past average across all plans and providers, not an offer.

These groups live in different regions with different delivery costs and weather, so the gaps describe the two markets in 2025, not what any household would pay elsewhere. Which parts of Texas can shop is set out in the Texas retail choice guide.

Next to Austin Energy and the Hill Country co-ops

The closest comparison is Austin Energy, the other large city-owned utility in Central Texas. In 2025 its residential customers paid 13.14¢ per kWh on average, against 12.40¢ per kWh at CPS Energy, after a rise of 4.5% on 2024 that CPS Energy did not have. Pedernales Electric Cooperative, which also reports customers in Bexar County, averaged 12.75¢ per kWh, and Bluebonnet Electric Cooperative 11.59¢ per kWh¹.

CPS Energy reports service in 8 counties: Atascosa County, Bandera County, Bexar County, Comal County, Guadalupe County, Kendall County, Medina County and Wilson County. In all 8⁶, at least one other utility reports customers too, so a county, city or ZIP code does not settle which utility serves a home; the utilities' own service-area maps decide by address.

The summer bill against the spring bill

CPS Energy bills follow the summer cooling season. Over the last 12 months (September 2025 to August 2026), use per CPS Energy home fell to 686 kWh in March 2026 and climbed to 1,523 kWh in August 2026. The average bill moved with it, from $92.50 to $205.21. A household budgeting on the 12-month average bill of $133.55² will fall short in the peak month.

Rooftop solar on a scale rare in Texas

CPS Energy reported 48,818 net-metered residential solar installations in 2025, with 414.4 megawatts of capacity. That is 54.9 per 1,000 residential customers, against 10.8 for Texas as a whole and 38.1 nationally. Advanced meters were installed at 99.7%⁸ of homes. How exported solar is credited is set in CPS Energy's own tariffs; the solar and net metering guide explains the general mechanics.

Outages and interruptions

CPS Energy customers averaged 111 minutes without power in 2025 including major events, fewer than the Texas average of 225 minutes, and 75 minutes excluding major event days. Each customer saw 1.54 interruptions on average, against 1.71⁹ statewide, both measured under IEEE 1366.

Commercial and industrial customers

CPS Energy's 97,661 commercial customers paid 10.09¢ per kWh on average in 2025, with an average monthly bill of $1,198.00. Its 34 industrial accounts paid 8.91¢ per kWh. All 986,641 accounts together averaged 11.09¢ per kWh¹. For statewide prices and the full list of utilities, see electricity in Texas.
