• Irrigation  more than 2 million acres of land in southern California and southwestern , and over 400,000 acres in Mexico • Municipal & Industrial Water  20 million people in Arizona , Nevada, and Southern California rely on municipal, industrial, and domestic uses • Reliable, Renewable, Valuable Hydro Power Resource  SRP has been utilizing Hoover power since the early 1950’s  Along with other AZ entities, supported and committed to the resource when it wasn’t the cheapest  SRP continues to purchase the Hoover Dynamic Signal and provides valuable energy banking benefits to APA customers

SRP and its 2 million customers rely upon both the water and power from the BCP. SRP has built electric and water systems, maintains those systems, and has spent millions of dollars enhancing the reliability of these systems to ensure delivery of both BCP water and power to Arizona.
