About electricity in Arizona
Natural gas is Arizona's largest source of electricity, but nuclear and solar each supply a sizable share. Public power utilities serve a large share of homes alongside the investor-owned companies.
- natural gas 45%
- nuclear 27%
- solar 13%
- coal 8%
- hydropower 4%
- wind 3%
The Arizona Corporation Commission is the state agency that regulates electric utilities in Arizona.
What drives electricity prices in Arizona
Arizona makes more electricity than it uses. Natural gas is the largest source, and the Palo Verde Generating Station west of Phoenix, which often produces more power than any other plant in the country, makes nuclear the second. Solar is a large and fast-growing share.
Who sets your rate depends on where you live. Arizona Public Service and Tucson Electric Power are investor-owned and regulated by the elected Arizona Corporation Commission. Salt River Project, a public power utility that serves much of the Phoenix area, sets its own prices through an elected board and is not regulated by the commission. There is no retail choice.
Prices are below the national average, but long, very hot summers mean Arizona homes use a lot of electricity for air conditioning. The large utilities offer time-of-use plans that charge more in the late afternoon and evening, when demand peaks.
