Shawnee Fossil Plant

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

Units 1 through 9 burn a blend of low-sulfur coal to limit sulfur dioxide emissions and use low-NOx burners to reduce emissions of nitrogen oxides.
Unit 10 — formerly used as a fluidized bed combustion boiler project — was idled in October 2010 and will be evaluated for possible conversion to generating power from biomass, such as wood waste.
As part of TVA's vision of being one of the nation’s leading providers of low-cost and cleaner energy by 2020, Shawnee units 1 and 4 will be converted to renewable biomass, controlled with scrubbers and selective catalytic reduction systems, or retired by Dec. 31, 2017.
