Since its inception in 1884, originally as Phoenix Light and Fuel Company, Arizona Public Service Company, the largest electric utility in Arizona, has generated clean, reliable, and affordable energy from nine power plants, now serving 2.7 million Arizonans. APS has long been recognized as a leader in water reuse, as demonstrated by its use of reclaimed water as cooling water for Palo Verde Generating Station, the largest producer of power in the United States for the last 25 years.
