The Johnsonville Combustion Turbine Plant is a 1.2 gigawatt simple cycle natural gas power plant located in New Johnsonville, Tennessee in Humphreys County, Tennessee. The TVA Johnsonville plant originally generated electricity as a coal power plant named the Johnsonville Fossil Plant from 1951 to 2017. It is operated by the Tennessee Valley Authority (TVA).

Coal units

Former Johnsonville Fossil Plant.

Construction of the fossil plant began in 1949.[1] The fossil plant started commercial operations at Unit 1 on October 27, 1951. By August 1959, all ten units were operating.[2] Its ten units had a combined operating capacity of 1.5-gigawatts (1,500 MW) with Units 1–4 providing electricity to the nearby Chemours plant.[3] In a 2011 agreement with the Environmental Protection Agency (EPA) to resolve lingering violation complaints in failure to comply with the Clean Air Act, the TVA announced they would shut down the coal units at Johnsonville by 2018.[4] Units 5–10 were idled at Johnsonville in 2012 and were shut down on December 31, 2015.[1][5] Units 1–4 were shut down on December 31, 2017.[1][6]

Natural gas units

In 1975 the TVA constructed 16 combustion turbine units at Johnsonville. Four more combustion turbine units were added in 2000. [7] These 20 units have a combined generating capacity of 1.2 gigawatts.[8] With the closure of the Johnsonville coal units, the TVA added a heat recovery generator to one of the combustion turbine units in 2017 to create the steam needed to produce titanium dioxide (TiO
2) at the nearby Chemours plant.[7]
