Arizona Electricity

What Arizona's Electricity Data Tells Us

Residential customers in Arizona pay 14.91¢/kWh in 2024, spread across 3.1M metered households, placing the state 9.5% below the national residential average of 16.48¢/kWh. Commercial rates sit at 12.23¢/kWh while industrial buyers pay 7.90¢/kWh, reflecting the cost differentials that come from voltage level, load factor, and contract length across EIA Form-861 survey respondents. Annual residential sales total 40.4M MWh on roughly $6027.5M in utility revenue, a useful yardstick for sizing local demand against the grid mix that serves it.

The generation mix is led by natural gas at 45.3% of in-state production, with nuclear providing 26.6% and solar supplying 13.4%. Renewable fuels, solar, wind, hydro, geothermal, and biomass, collectively account for 19.8% of Arizona's electricity output, a figure that matters because each renewable megawatt-hour displaces fuel costs that otherwise flow through to retail bills. Expansion headroom remains: cost curves for wind and solar have fallen faster than fossil alternatives for most of the last decade.

Looking back across EIA records, residential prices in Arizona moved from 12.15¢/kWh in 2016 to 14.91¢/kWh in 2024, a 22.7% shift over that window. Comparable-priced neighbors include Colorado, Texas, Nevada, which gives a peer set for sanity-checking local quotes. For anyone negotiating a supplier contract, weighing an energy-efficiency upgrade, or modeling a household budget, the combination of current rate, multi-year trend, and generation mix offers a sturdier footing than any single data point on its own.
