What drives electric bills in Arizona
Residential electricity in Arizona averaged 15.4¢ per kWh in January–July 2026, up 0.9% from 15.3¢ in the same months a year earlier (the U.S. average went up 6.9%). In July 2026, the latest month available, it was 15.4¢. The typical home here used 1,075 kWh a month in 2024, 25% more than the U.S. average, so how much power you use matters as much as the price.
- Extreme summer heat. In Phoenix and Tucson, air conditioning runs almost nonstop from May to October, and it accounts for most of the summer bill.
- Time-of-use rates. APS, SRP and TEP put most homes on plans that charge much more on weekday afternoons and evenings, typically in a window between 3 and 8 p.m. Running the A/C, dryer and oven in those hours costs the most.
- Pool pumps. Many Arizona homes have a pool, and its pump can add a lot to the bill.
Who supplies your power
Arizona Public Service (APS) serves Phoenix-area suburbs and much of the state, Salt River Project (SRP), a public power utility, serves much of metro Phoenix, and Tucson Electric Power (TEP) serves Tucson. Co-ops and small utilities serve rural areas.
Ways to pay less in Arizona
- Pre-cool your home before the peak window starts and set the thermostat higher during it. Check your plan’s exact peak hours on the bill.
- Run the pool pump outside peak hours and fewer hours a day. A variable-speed pump can cut its cost by more than half.
For example, a 1,500 W space heater running 8 hours a day costs about $56 a month at Arizona prices. Check what your appliances cost to run in Arizona.
Help paying your bill in Arizona
- Low-income discount programs: APS Energy Support, SRP’s Economy Price Plan and TEP’s Lifeline discount lower monthly bills for qualifying households.
- LIHEAP: Arizona’s program helps with cooling and heating bills through community action agencies. Arizona rules also limit disconnections for nonpayment during the hottest summer months.
Statewide help is in addition to the federal programs, such as LIHEAP and weatherization, that the bill checker above lists. Call 211 to find the agency that handles them near you.
Is solar worth it in Arizona?
A typical 7 kW rooftop system in Arizona produces roughly 11,550 kWh a year, about 90% of what an average home here uses. At the state’s average price of 15.4¢, that power is worth about $1,783 a year. What you actually save depends on your roof, the price you pay for the system, the 30% federal tax credit rules in effect when you buy, and how your utility credits the power you send to the grid.
