John Sevier Fossil Plant
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:
- The plant is equipped with electrostatic precipitators that capture ash from the burning coal.
- The use of low-sulfur coal from Virginia reduces emissions of sulfur dioxide (SO2 ).
- Low-NOx burners limit the production of nitrogen oxides (NOx), which contribute to the formation of ozone and acid rain.
