Cumberland Fossil Plant Emissions

What TVA is doing about emissions at Cumberland

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

  • Wet limestone scrubbers remove 95 percent of sulfur dioxide from the plant’s emissions.
  • Both Cumberland units are equipped with selective catalytic reduction systems completed in 2004 and low-NOx burners that reduce nitrogen oxide emissions by about 90 percent.
