Arizona Electricity Prices

Arizona sits mid-pack — 15.23¢ per kilowatt-hour in May 2026, 32nd-highest of 51 and 21.5% below the national benchmark.

At Arizona's May 2026 average of 15.23¢/kWh, 10,500 kWh of annual use works out to $1,599 a year — around $133 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $439 gap between the two published averages, less for Arizona, not a bill either way.

Over the full EIA series the Arizona jurisdiction average has risen 118% since January 2001, from 6.99¢ to 15.23¢ in May 2026 — a compound 3.1% per year. Arizona is among the most month-to-month variable third of jurisdictions.

February 2026, at 16.03¢ per kilowatt-hour. The May 2026 reading of 15.23¢ sits 5.0% below that peak. The lowest monthly average on record was 6.99¢ in January 2001.

May. Measured over the 25 complete calendar years the EIA series covers for Arizona, 2001 through 2025, May runs highest relative to its own year and January runs lowest — a swing of roughly 16.7 percentage points.

Among Arizona and its land-border neighbours in May 2026, Utah posts the lowest average at 12.96¢ and California the highest at 33.25¢. Arizona ranks 4th of 5 in the group, at 15.23¢.

Almost certainly not exactly, and this is the one caveat that governs every figure on this page. The published value is the EIA residential average across every utility and residential rate class in Arizona for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 15.17¢ in August 2025 and 16.03¢ in February 2026. Your own rate depends on your utility, tariff, usage tier, time-of-use schedule, and fixed monthly charges, none of which this index models. Read your bill for the rate that applies to you.
