Arizona's summer and winter bills
An Arizona bill depends on the month more than anything else. Over the last year the average home used 1,789 kWh in August 2026 and 636 kWh in February 2026, so the peak bill was 2.6 times the low one.[eia861m] Air conditioning in the desert summer drives the peak; winters in Phoenix and Tucson are mild, so heating adds little.
Arizona U.S. average
Because of the swing, a single summer bill makes Arizona look far more expensive than it is over a year. The 12-month average of $162.13 ranks 19th highest of 51, and the price of 15.39¢ per kWh ranks 30th highest, below the U.S. average of 18.04¢. The average bill changed +1.7% from $159.48 a year earlier.[eia861m]

A budget built on the 12-month average needs savings from the cheap months to cover July and August. Arizona utilities offer plans that charge more in late-afternoon summer peaks and less at other times, so shifting laundry, dishwashing and pool pumps away from the peak lowers the rate as well as the kWh.
What to check on a high Arizona bill
- kWh against the same month last year. The table above gives the state average for each month.
- Your rate. Divide the total by the kWh and compare it with your utility's row; the electricity cost calculator does the math for any rate.
- AC size and age. The HVAC size calculator estimates the cooling load and heat pump cost the yearly running cost.
Every state's bill is on average electric bill, and Arizona's price against the rest on electricity rates by state.
