Arizona electricity prices and utilities
Households in Arizona paid an average of 14.91¢ per kilowatthour for electricity in 2024, 9.5% below the US average of 16.48¢. That ranks 26th highest of the 50 states and the District of Columbia.
The average residential bill was $160.24 a month on 1,075 kWh of monthly use (US: $142.26 on 863 kWh), the 9th highest bill. Residential sales came to 5,304 kWh per resident over the year.
In July 2026, the latest month EIA has published, the residential average was 15.38¢, little changed on July 2025; the US figure for the month was 18.31¢. Monthly figures are preliminary until EIA finalises the year.
19 respondents reported residential customers in Arizona on the full Form EIA-861 for 2024, and 25 smaller utilities filed the short form, which has no residential breakdown. Investor-owned utilities account for 57% of the residential customers reported.
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. State averages are EIA's own, from Forms EIA-861 and EIA-861M.

Reliability by utility, 2024
SAIDI: minutes of sustained interruption per customer over the year, including major event days (paler bars: the utility reported only the figure without major event days). Median across 13 Arizona filings: 113.2 minutes with major event days, 80.9 without. EIA's state total: 87.5 and 72.0 minutes, with SAIFI of 0.99 interruptions per customer. Utilities use differing calculation methods, and a single storm can dominate a small utility's year.
