The Palo Verde Nuclear Generating Station®, located about 55 miles west of downtown Phoenix, has been the largest power producer of any kind in the United States since 1992. Its three units are capable of generating more than 4,000 megawatts of electricity.
Because of its desert location, Palo Verde is the only nuclear plant in the United States that does not sit on a large body of water. Instead, it uses treated effluent from several area municipalities to meet its cooling water needs, recycling approximately 20 billion gallons of wastewater each year.
Palo Verde, which has an economic impact of approximately $1.8 billion annually and is the largest single commercial taxpayer in Arizona, is operated by APS and is owned by a consortium of seven utilities in the Southwest. APS owns 29.1 percent of the plant.
