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. Sometimes, legislation specifies a geographic area that receives priority to Federal hydropower. WAPA also places geographic limits on the marketing of power, which define the location of eligible customers. Marketing area boundaries are usually based on past marketing practices, the location of the powerplants generating the electricity being sold, state boundary lines or river drainages. Transmission Infrastructure Program Section 402 of the American Recovery and Reinvestment Act of 2009 amended the Hoover Power Plant Act of 1984 to give WAPA authority to borrow up to $3.25 billion from the U.S. Treasury to pursue transmission projects that promote the delivery of renewable generation into the electric transmission grid. To implement that authority, WAPA created the Transmission Infrastructure Program (TIP). Two projects have been completed under this authority, and several others are in the development process. Agency organization WAPA employees conduct power sales, transmission operations and maintenance and engineering services at 51 duty stations organized under four regions, a management center and headquarters. The regions and management centers oversee the power and transmission contracts, operations and maintenance while centralized functions, such as finance, information technology, safety and security, are handled by headquarters.
