What Arizona power is made of

In plain words. Natural gas is the biggest source in Arizona (45%), and the power made there is cleaner than the U.S. average per kWh. Plants with 425 MW are planned to retire by 2030. New plants with 5,756 MW are under construction.

In 2025 Arizona plants of 1 MW or more made 116.4 TWh. The biggest sources: natural gas 45.2%, nuclear 26.9%, utility-scale solar 13.3%. For comparison, natural gas makes 40.9% of U.S. generation. Wind, solar and hydro together: 20.1% (22.6% for the U.S.). Arizona plants only; imports and rooftop solar are not counted.

Analyst note

Arizona residential power was 24th highest of 51 in 2015 at 12.13 ¢ and is 26th in 2024 at 14.91 ¢, so the state slid down 2 places. The U.S. figure went 12.65 to 16.48 ¢ while Arizona went +22.9%. The biggest annual move was 2023 at +7.7%; the latest year, 2024, came in at +6.3% against +3.0% for the U.S. Business customers paid 10.39 ¢ in 2015 and 12.23 ¢ in 2024, a gap to homes of -1.74 ¢ then and -2.68 ¢ now; industry went from 6.26 to 7.90 ¢ (+26.2%). Reliability changed little at the 7 Arizona utilities that report in both years: their median SAIDI went from 72 minutes in 2015 to 81 in 2024, +12%, against a U.S. median reporter of 99. Arizona Public Service Co is the largest by accounts with 1,400,037, 40.1% of the 3,490,713 accounts in Arizona, and the top three hold 86.6%.

At 14.91 ¢/kWh, Arizona residential power is mid-table in the country: 26th of 51, 1.57 ¢ below the U.S. figure. Since 2015 the residential price moved +22.9% against +30.3% nationally, so Arizona has slipped behind the national trend by 7.4 points.

Businesses pay 2.68 ¢ less than households here (-18.0%); business is under home price in 51 of 51. The median of 11 reporting utilities is 80.9 SAIDI minutes, 19% under the national median. The top three utilities hold 87.9% of accounts, so a few reliability records set the state picture.

By revenue, Arizona electricity splits 52.1% residential, 38.1% commercial and 9.8% industrial; by kWh the split is 44.5%, 39.7% and 15.7%. Residential accounts are the largest revenue source here. Home accounts are 89.8% of 3,490,711 accounts and use 1,075 kWh a month, a commercial account 8,634 and an industrial one 157,709.
