The powerhouse of the U.S. Tennessee Valley Authority's Wilson Dam spans the south end of the dam. The neoclassical style dam was the first built on the Tennessee River and dates to its completion in 1924. It was originally built to provide power to the U.S. government's nearby nitrate plants, which were built to provide ammonium nitrate for military explosives. With the TVA Act, the dam was turned over to the TVA in 1933. The powerhouse contains 21 generators totaling 663 MW of net dependable power capacity.
