John Sevier Fossil Plant Emissions

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 environmental agreements, TVA retired two units on Dec. 31, 2012, and retired the remaining two coal units on June 25, 2014.
  • 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.
