Various laws, including the Reclamation Project Act of 1939, require WAPA to give preference to certain types of non-profit organizations seeking to purchase Federal power. Preference customers include state and Federal agencies, water and irrigation districts, municipalities, public utility districts, Native American tribes and rural electric cooperatives. A law may also designate specific entities that must receive preference in power sales from a particular powerplant or project. WAPA has some discretion regarding which preference entities should receive power and has allocated power to wildlife refuges, universities and mass transit systems.
