Southwestern's rates, by law, are designed to recover the costs of producing the power. These costs include repayment of the dams' initial construction, with interest; repayment of the transmission system construction, with interest; major replacements; and both the Corps of Engineers' and Southwestern's annual operating and maintenance expenses. Annual revenues vary with water conditions, but generally average about

' system for the states of Texas, Arkansas, Oklahoma, and Missouri (and a few more states who would be customers to these dams' energy production) but only for the federally-built dams and their hydroelectric power plants. Other power plants like fossil fuel plants were not going to be owned and managed by the SWPA like Tennessee's power plants. The reason for the creation of the SWPA was the fear that the federal dams, which are multipurpose in terms of flood control and water storage for recreation and human use, would be poorly managed by private businesses and also because utility companies during the 1920s and 1930s hiked up electricity prices in rural areas far higher than in urban areas. The SWPA was a hallmark of Rayburn's campaign to provide electricity to all farmers and rural Americans. He previously succeeded in the landmark

The SWPA (as well as the establishment of the other three Power Marketing Administrations) and the guaranteed cheap electricity from dams helped the REA's goals to be realized.
