Arizona Utility Cost Calculator
Arizona’s average residential customer paid $161.85 a month for 1,051 kWh at 15.40¢ per kWh over the last 12 months — and far more than that in midsummer.
Arizona figures
APS, SRP and Tucson
Two retailers supply most Arizona homes. Arizona Public Service, investor-owned and regulated by the Arizona Corporation Commission, delivered 15.6 TWh to residences in 2024; Salt River Project, a public power entity, delivered 15.3 TWh. Tucson Electric Power and UNS Electric are the other large investor-owned names. Public entities made 41% of all retail sales — fourth-largest public share in the country — so many Arizona households pay rates that never pass through the Commission. Check the plan name on your bill before leaning on the 15.40¢ statewide average.
Air conditioning is the bill
No state’s homes spend more electricity on cooling: the 2020 household survey found about 5,165 kWh a year of air conditioning in an Arizona home that uses it, against 1,299 kWh for electric space heating. The seasonal swing follows — the average residential bill reached $263.16 in July 2026 and dropped to $101.91 in February 2026, more than a 2.5-fold difference.
Gas made 47% of 2024 generation and nuclear 28% — Palo Verde produced more electricity than any other plant in the state — with solar at 9%. Coal fell from 38% of the mix in 2014 to 8%. Rooftop solar is common: 317,033 homes had net-metered systems at the end of 2024, second only to California, or about 9% of residential meters.
Gas and help with bills
About half of homes have gas service, mostly for water and space heating, and the typical gas account uses only 304 therms a year — third-lowest nationally. Help with energy bills comes from the Division of Community Assistance and Development at the Arizona Department of Economic Security.

Worked example
Electric cooling, gas water heater and furnace — a Phoenix-area house at state averages:
- Electricity: 1,051 kWh × 15.40¢ = $161.85
- Natural gas: 25.3 therms × $1.814 = $45.89
$207.74 a month · $2,492.98 a year
