State Profile and Energy Estimates

Changes to the State Energy Data System (SEDS) Notice: In October 2023, we updated the way we calculate primary energy consumption of electricity generation from noncombustible renewable energy sources (solar, wind, hydroelectric, and geothermal). Visit our Changes to 1960—2022 conversion factor for renewable energy page to learn more.

Profile Overview

Quick Facts

  • Arizona's Palo Verde Nuclear Generating Station is the largest nuclear power plant, the largest net generator of electricity, and, with a net summer capacity of 3,937 megawatts, the second-largest power plant of any kind in the nation. In 2022, it accounted for 4% of the nation's nuclear generation.
  • Arizona ranks second in the nation in solar energy potential after Nevada, and in 2022, it was fifth in solar-powered net generation from the state's utility- and small-scale photovoltaic and solar thermal power plants together. Solar energy provided the state with more power than all of Arizona's other renewable energy sources combined.
  • In part because of its large population and mild winter climate, Arizona consumed less total energy per capita than almost four-fifths of the states in 2020. 
  • In 2022, 99% of Arizona's total electricity net generation was provided from 6 sources: natural gas (42%); nuclear power (29%); coal (12%); solar energy (10%); hydroelectric power (5%): and wind (1%). Biomass, hydroelectric pumped storage, and petroleum, supplied the rest.
  • In 2022, Arizona hydroelectric power plants supplied their smallest amount of electricity in more than 30 years. They accounted for about 5% of Arizona's total in-state electricity generation.
