Johnsonville Cogeneration Plant

Humphreys County, Tennessee

On July 1, 2015, TVA issued a Final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for a Johnsonville Cogeneration Plant near New Johnsonville, Tennessee.

The Johnsonville Fossil Plant (JOF) is the oldest fossil plant in the TVA system. It has 10 coal-fired units which produce approximately 6 billion kilowatt-hours of electricity per year, enough to supply 400,000 homes. In April 2011, TVA entered into an agreement with EPA, several states, and three environmental advocacy groups, and TVA agreed to retire all 10 coal-fired units at JOF by December 31, 2017.

TVA currently provides steam produced by the coal-fired units to an external customer. The existing contract to provide steam will extend to December 2017 when the coal-fired units at JOF are retired. TVA evaluated actions to continue to provide steam to the steam customer following the retirement of all the coal-fired units. The preferred alternative is to construct and operate a heat recovery steam generator (HRSG) integrated into an existing combustion turbine (CT).

A draft of the EA was issued for public review and comment from April 20, 2015 to May 18, 2015. TVA responded to the comments received in Appendix A of the Final EA.
