What businesses in Tempe pay
Across Arizona, businesses paid an average 12.22¢ per kWh over the 12 months to August 2026, 11.9% below the U.S. average of 13.87¢, and down 1.8% on the 12 months before. That ranks Arizona 28 of 51, where 1 is the highest price. In 2025 the average commercial account in the state used 8,893 kWh a month, about $1,107 a month at the state price; that is a mean pulled up by a few very large users, so most small businesses use less.
A city has no price of its own: two businesses on the same street can pay very different amounts per kWh, because the rate schedule, the size of the peak and, where it is allowed, the supply contract matter more than the location. The Arizona page has the state’s price history since 2010 and every utility with at least 500 commercial customers.
Choosing a supplier in Tempe
Arizona commercial accounts generally purchase supply from their regulated utility. Rate schedule selection, demand charges, solar and storage, and load shifting drive far more cost movement than any supply question.
Where prices are heading

Common questions
- Who provides electricity to businesses in Tempe?
- EIA lists APS, SRP, City of Mesa and USBIA-San Carlos Project and 9 more as electric utilities in Maricopa County. Which one serves a given address depends on the street; the utility on an existing bill is the definitive answer, and a utility can confirm service for a new site.
- What is the average commercial electricity rate in Tempe?
- There is no official figure for a city. EIA publishes prices by state and by utility: APS averaged 13.45¢ per kWh for its commercial customers in 2025, and Arizona averaged 12.22¢ over the 12 months to August 2026. A business’s own price depends on its rate schedule, its demand and, where it can choose, its supply contract.
- Can a business in Tempe choose its electricity supplier?
- Arizona commercial accounts generally purchase supply from their regulated utility. Rate schedule selection, demand charges, solar and storage, and load shifting drive far more cost movement than any supply question. The state page for Arizona explains how it works and who regulates it.
