Johnsonville Fossil Plant
TVA’s Johnsonville Fossil Plant is located on 720 acres of land near Waverly, Tenn. It is named for the town of Johnsonville, which was flooded during the formation of the adjacent Kentucky Lake. The town was relocated several miles south and named New Johnsonville.
Johnsonville is the oldest fossil plant in the TVA fleet. Plant construction began May 12, 1949 with the first of the plant’s 10 operating units going into service Oct. 27, 1951. The final unit began generating electricity on Aug. 20, 1959.
Johnsonville's current net summer capability is 428 megawatts. Units 1 through 4 also provide steam to a nearby DuPont plant in a co-generation configuration. Johnsonville is the only TVA coal-fired co-generation facility.
Nevertheless, units 1 through 4 will cease generation by December 2017, as part of a consent decree with the Environmental Protection Agency (EPA). Units 5 through 10 were idled in 2012.
