The rate on the record
Municipal residential rates are often set by a city board, not the state commission. Needs verification. Average revenue per kilowatt-hour is total residential revenue divided by residential sales. It is not a tariff schedule.

Audit the full service average
Revenue 1,422,390.1 thousand dollars. Sales 11,467,604 MWh. Customers 888,946. Cents per kWh = revenue ÷ megawatt-hours × 100. Monthly bill = revenue × 1,000 ÷ customers ÷ 12.
Why a City of San Antonio bill moved
Usage and price pulled in opposite directions
Hold a City of San Antonio household to the filing average and the monthly full service bill changed +0.2% between those two EIA years. Holding the 2024 price fixed, the usage change of +0.4% is worth $0.56 a month. The price change of −0.2%, from 12.43¢ to 12.40¢, is worth −$0.28 on 2025 usage.
Below the Texas average
12.40¢ per kWh is below Texas's 2025 residential average of 15.40¢. July 2026 in the state was 15.88¢, versus 15.36¢ a year earlier (+3.4%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 1,075 kWh will not land on $133.34.
Not a typical investor-owned rate case
City of San Antonio is municipal in the EIA filing, so retail rates are often set by a city council or utility board rather than a state commission docket. The 2025 full-service average was 12.40¢ per kWh. Which board adopted the current tariff needs verification unless a decision is cited below.

Season
City of San Antonio customers in Texas average 1,075 kWh a month across the whole year, against a statewide residential average of 1,110 kWh. Summer afternoons do not look like that average. An air conditioner, a pool pump, or a hotter month can move the bill before any rider does.
Data-center load is not a line on this bill
National electricity demand is rising, and EIA points to large computing facilities. No retrieved order isolates a data-center dollar on a City of San Antonio residential account. That pass-through needs verification.

How to lower the bill
- Read the kilowatt-hours against this filing's average of 1,075 kWh a month. If your use is the thing that moved, the dollar total can rise on an unchanged rate.
- On the statement, separate the base energy charge from fuel or rider lines. A rider can move the total in a month when no new base-rate order exists.
- In Texas, the expensive hours are late afternoon and early evening in summer. Raise the cooling setpoint when you are out, and run the dryer, the dishwasher, and any pool pump outside those hours if your tariff charges more then.
- Start with LIHEAP for Texas (https://www.acf.hhs.gov/ocs/map/liheap-map-state-and-territory-contact-listing). A City of San Antonio discount beyond that program needs verification.
- If the read is marked estimated, the next actual read can true the account up or down. The tariff rule for that true-up needs verification.

The current offer, income cutoff, and how to apply need verification with the state LIHEAP office and Public Utility Commission of Texas.
