Why Arizona pays what it pays
The Palo Verde Generating Station is the largest power plant in the United States by output, and it sits west of Phoenix. Its energy is low-cost, carbon-free and long since built, and it supplies a large share of Arizona's electricity along with power sold into California and elsewhere.
Arizona has also added utility-scale solar rapidly, which is well matched to a load shape dominated by afternoon air conditioning, and increasingly battery storage to push that solar output into the evening peak.
The state's population growth adds customers faster than most, which spreads fixed costs across a widening base. It is one of the more underrated reasons fast-growing Sun Belt states have held rates relatively well.
Where Arizona power comes from
Arizona generated 117 TWh in 2025, the 12th largest output of any state. Natural gas supplied 45.1% of it. Renewables accounted for 20.5%, against 23.8% nationally, which ranks Arizona #23 of 51.
- Natural gas 45.1% 53 TWh
- Nuclear 26.8% 31 TWh
- Solar 13.4% 16 TWh
- Coal 7.9% 9 TWh
- Hydroelectric 4.2% 5 TWh
- Wind 2.7% 3 TWh

Heating in Arizona: gas, heat pump or resistance
Residential natural gas in Arizona averaged $20.47 per thousand cubic feet in 2024, about $1.97 per therm, against a national average of $14.50. Put on the same scale as the state's electricity rate, the cost of delivering one million BTU of heat works out as follows.
In Arizona, a heat pump is cheaper to run than a gas furnace by about $7.05 per million BTU at these assumptions. Over a 60 million BTU heating season that is roughly $423, before counting the cooling a heat pump also provides.

What each Arizona utility charges
The statewide average hides a wide spread. Across the 22 Arizona utilities reporting to the EIA, rates run from 9.60¢ at Dixie Escalante R E A, Inc to 19.49¢ at USBIA-San Carlos Project . Together they serve 3.2 million residential customers.

Who sells electricity in Arizona
Arizona Public Service serves much of the state. Salt River Project, a public power utility, serves a large part of the Phoenix metropolitan area and is governed by an elected board rather than the state commission. Tucson Electric Power serves Tucson, and co-operatives serve rural areas.
There is no residential retail choice. The Arizona Corporation Commission, whose five members are elected statewide, regulates the investor-owned utilities. SRP sets its own rates.
Arizona sits in The Mountain West. Cheap legacy coal and abundant sun, with costs decided by how fast each state is retiring one and building the other. Read the regional analysis.
What you can actually do about it
Arizona has the most complicated residential rate menu of any state. APS and SRP both offer multiple time-of-use plans, demand-charge plans and flat plans, and the difference between the best and worst choice for a given household is large. Both publish rate comparison tools using your own historical usage. Use them.
Demand-charge residential plans can be excellent for households that never run several large appliances at once, and punishing for those that do.
Closest states by price
These jurisdictions charge within a fraction of a cent of Arizona, which is useful if you are comparing a move or a multi-state operating cost.
Arizona electricity rates: common questions
What is the average electricity rate in Arizona?
The average residential electricity rate in Arizona is 15.23 cents per kilowatt-hour as of May 2026, according to the U.S. Energy Information Administration. That is -17.4% relative to the national average of 18.44¢/kWh.
How much is the average monthly electric bill in Arizona?
The average Arizona household paid $160 a month across the twelve months to May 2026, using an average of 1,041 kWh. That is +3.1% against the U.S. average bill of $155, and it ranks 19th highest of the 51 jurisdictions. Your own bill depends on the size of your home, your heating and cooling equipment and your rate schedule.
Why is the Arizona bill ranking different from its rate ranking?
A bill is the rate multiplied by usage, and usage varies between states more than price does. Arizona ranks #32 of 51 on price but 19th on the actual bill, because households there use about 1,041 kWh a month against a national average of 871. Climate and heating fuel drive most of that difference.
Have electricity rates in Arizona gone up?
Arizona rates fell 3.1% over the year to May 2026, from 15.71¢ in May 2025 to 15.23¢.
Can I choose my electricity supplier in Arizona?
Regulated monopoly. Arizona households buy both supply and delivery from their local regulated utility or co-operative; there is no competitive residential supplier market.
