Widows Creek Fossil Plant

What TVA is doing about emissions at Widows Creek

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

  • Units 7 and 8 are equipped with wet limestone scrubbers to remove particulates and sulfur dioxide emissions. These units also use low-NOx burners to reduce the production of nitrogen oxides.
  • TVA has installed selective catalytic reduction systems on units 7 and 8 to further reduce nitrogen oxide emissions by about 90 percent.
  • As of Oct. 1, 2011, the plant’s six other units have been idled — earlier than their retirement as required by an agreement with the Environmental Protection Agency, state environmental agencies and other parties.
