Colbert Fossil Plant Emissions

What TVA is doing about emissions at Colbert

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

  • Colbert burns low-sulfur coal to limit emissions of sulfur dioxide.
  • Low-NOx burners limit emissions of nitrogen oxides.
  • In support of environmental agreements, Colbert unit 5 has been idled and will be retired by Dec. 31 2015. Units 1 through 4 will be retired by June 30, 2016.
  • Colbert combustion turbines burn low-emitting natural gas or ultra-low-sulfur fuel oil.
