Allen Fossil Plant

TVA has taken a number of steps to make the efficient generation of power at Allen 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 the western United States limits emissions of sulfur dioxide.
A technology called overfire air limits the production of nitrogen oxides that contribute to the formation of ozone and acid rain. This technology involves modifications that reduce the oxygen available to form nitrogen oxides in the furnaces’ combustion zones.
All three units at Allen operate selective catalytic reduction systems reducing nitrogen oxide emissions by up to 90 percent.
In support of recent environmental agreements and its vision of being one of the nation’s leading providers of low-cost and cleaner energy by 2020, TVA will add scrubbers to all three units at Allen by Dec. 31, 2018.
