What TVA is doing about emissions at John Sevier

TVA has taken a number of steps to make the efficient generation of power at John Sevier as clean as possible:

  • In support of recent environmental agreements and its vision of being one of the nation’s leading providers of low-cost and cleaner energy by 2020, TVA retired two units and removed from service the remaining two coal fired units on December 31, 2012.
  • John Sevier Combined Cycle units burn low emitting natural gas or ultra-low sulfur fuel oil.
  • All combined cycle units are equipped with dry low NOx burners and SCRs to reduce NOx emissions.
