Arizona electricity rates, bills and the summer peak

What Arizona homes pay per kWh

Over the 12 months from September 2025 to August 2026, Arizona's residential customers paid an average of 15.39¢ per kWh, 14.7% below the US average. That placed Arizona 22nd from the lowest among the 50 states and DC. In August 2026, the latest month published (preliminary), the average was 15.05¢ per kWh, −0.3%¹ against August 2025. Average revenue per kWh is what customers paid in total, fixed charges and adjustments included, divided by what they used; it is not the price on any single rate plan.

Two things about that number stand out. It barely moved: the 12-month average was +1.7% against the 12 months before, the 6th lowest increase among the states, while the national average rose 6.5%. And it falls in summer. Over the same 12 months Arizona's monthly average was highest in February 2026 (16.03¢ per kWh) and lowest in August 2026 (15.05¢ per kWh¹). A general mechanism is at work: when use per home rises steeply in summer, each month's fixed customer charges are spread over many more kWh, so the average per kWh drops even as the bill climbs.

Peak-month bills lead the country

In August 2026 the average Arizona home used 1,789 kWh, the highest among the states, and the computed average bill was $269.26. The US average that month was $209.23 for 1,152 kWh. Arizona's average price that month, 15.05¢ per kWh, was below the US average of 18.16¢ per kWh¹; the gap in the bill comes from volume.

Across a whole year the picture is milder. The 2025 average bill was $157.15 a month for 1,030 kWh, the 16th highest in the country and $6.47 more a month than the US average². Over the last 12 months the computed average was $162.13. Winter months pull the annual figure down: use per home fell to 636 kWh in February 2026, so the peak month used 2.8 times¹ as much electricity as the lowest.

The bill fell from 2024 to 2025, by 1.9% to $157.15, the 4th lowest change among the states, while the US average bill rose 5.9%. Arizona's annual average price rose 2.3%³ over the same period, but use per home dropped from 1,075 kWh⁴ to 1,030 kWh² a month. In a state where summer cooling dominates, the weather of a single year can outweigh a price change.

Air conditioning, not heating

Air conditioning accounted for 36% of household electricity use in Arizona in EIA's 2020 Residential Energy Consumption Survey, the highest share among the states; the US share was 19%. Space heating took 6%⁵. NOAA's degree-day records match that split: Arizona averaged 2,655 cooling degree days a year from 2016 to 2025, 3rd highest among the states with NOAA data, and 2,041 heating degree days, 4th lowest⁶.

Electric heat is common anyway: 60.8% of Arizona households heated mainly with electricity in the Census Bureau's 2025 survey, against 41.8%⁷ nationally. The 2020 survey also put an Arizona household's annual electricity use at 13,598 kWh a year and its spending at $1,737, the 4th highest⁵ among the states (2020 figures, a pandemic year; the next survey's state results are due in spring 2027).

Households' own reports of their bills sit close to the national pattern. The Census Bureau's 2025 survey put the median monthly electricity bill reported by Arizona households at about $169, against a US median of $169; 27.3% reported $250 or more (±0.5 percentage points⁸). These are recalled bills for an average month, taxes included, and estimates with margins of error.

APS, SRP and Tucson Electric Power

Three utilities deliver electricity to 87.9% of Arizona's residential customers: APS (40.7%), Salt River Project (34.0%) and Tucson Electric Power (13.2%⁹). In 2025 their residential customers paid, on average:

APS customers paid the most per kWh of the three, 11.6% above the Arizona average. SRP customers paid less per kWh but used more electricity, so their average bill came close to APS's. Tucson Electric Power customers used the least and had the lowest average bill of the three; against 2024, their average bill was −6.8% and their average price −4.8%. At APS and SRP the average price rose over the same year (+3.5% and +3.9%) while their average bills fell (−3.2% and −2.0%⁹), again because homes used less.

The summer swing differs by utility too. In its peak month, August 2026, SRP's average home used 2,041 kWh and was billed $282.07. APS homes used less at their peak (August 2026), 1,727 kWh, yet were billed more, $291.13; Tucson Electric Power's peak (August 2026) came to 1,336 kWh and $197.92¹⁰ (preliminary monthly data).

Which utility serves your address

Arizona has no retail choice for households: in 2025, 0.0%⁹ of residential customers bought electricity from a competitive supplier. The utility is set by location. EIA's service-territory records list 13 distribution utilities in Maricopa County alone, the county of Phoenix and Mesa, among them APS, SRP and the City of Mesa. Tucson Electric Power reports service in Cochise County and Pima County; APS reports service in 14¹¹ of the state's 15 counties. A county or city name is not enough: each utility's own service-area map decides by address, and there is no official average price for a city.

Regulation differs by owner. The Arizona Corporation Commission regulates investor-owned utilities such as APS and Tucson Electric Power and states that it has no jurisdiction over city-owned utilities.

Time-of-use plans and rooftop solar

Arizona households are far more likely than most to be billed by time of day. In 2025, 37.7% of residential customers were enrolled in a time-varying rate, the 6th highest share among the states, against 11.3% nationally. APS reported 58.0% of its residential customers on such plans, SRP 33.6% and Tucson Electric Power 16.4%. Advanced meters, which make those plans possible, were installed at 94.3%¹³ of homes.

Rooftop solar is common as well. Arizona had 333,870 net-metered residential solar installations in 2025, 104.2 per 1,000 residential customers, the 4th highest rate among the states (US: 38.1). APS customers had 148.0¹³ per 1,000. Net-metered homes buy less electricity from their utility, and time-of-use customers pay different prices by hour, so the statewide average blends very different bills. The time-of-use guide explains how such plans change a bill.

Where the power comes from

Natural gas produced 45.2% of Arizona's electricity in 2025, nuclear power 26.9% and solar 13.3%, the 6th highest solar share in the country. Coal fell from 32.0% of generation in 2015 to 7.9%, while gas rose 15.5 percentage points and solar 10.2 percentage points. Arizona's plants generated 116.5 terawatt-hours in 2025, the equivalent of 127%¹⁴ of the state's retail sales, so the state produces more electricity than it sells to its own customers.

Arizona against its neighbors and over time

Below the US average does not mean cheap for the region. Over the last 12 months, 3 of Arizona's 4 neighbors had a lower residential average, with Utah lowest at 13.26¢ per kWh. California had the highest, at 32.34¢ per kWh¹.

Over the long run, Arizona's residential average rose from 8.30¢ per kWh¹⁵ in 2001 to 15.26¢ per kWh in 2025, an increase of 83.9%; the national average rose 100.8% over the same years. The annual average went up in 21 of the years since 2002 and last fell in 2020³. Businesses saw small declines recently: over the last 12 months the commercial average was −1.8% (12.22¢ per kWh) and the industrial average −2.7% (7.83¢ per kWh¹) against the 12 months before.

Outages and help paying

Arizona customers averaged 74 minutes without power in 2025, including major events, the 3rd lowest total among the states, and 0.93 interruptions per customer. Tucson Electric Power customers averaged 42 minutes in 2025, APS customers 73 minutes and SRP customers 66 minutes¹⁶.

Federal energy assistance is thin relative to the number of households. Arizona received $35.5 million from the Low Income Home Energy Assistance Program (LIHEAP) for fiscal 2026, $11.67 per occupied household, the lowest amount among the states; the first fiscal 2027 release was $29.9 million¹⁷. Application steps and other sources of help are listed in the help paying your electric bill guide.
