The District provides electricity to retail customers in the Phoenix area. It operates or participates in seven major power plants and numerous other generating stations, including thermal, nuclear and hydroelectric sources.
During the Great Depression, Valley farmers were hard-pressed to make payments on the federal loans for Theodore Roosevelt Dam and other dams on the Salt River. To help reduce payments on the outstanding loans, the Arizona Legislature enacted a law in 1936 that allowed the formation of the Salt River Project Agricultural Improvement and Power District in 1937.
As a political subdivision of the state, the District can issue tax-exempt municipal bonds, thereby reducing interest costs and saving SRP electric and water users millions of dollars.
As the Valley's population has grown, the District has tapped many power sources to provide electricity to more than 929,000 customers. Besides the time-honored hydroelectric generating units at the dams on the Salt River, the District owns or participates in 10 generating stations in the Southwest. Customers also are served by power drawn from various other generating facilities in the Valley and state, as well as from contractual power purchases.
