Allen Fossil Plant Emissions

What TVA is doing about emissions at Allen

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 coal units at Allen operate SCRs, reducing nitrogen oxide emissions by up to 90 percent.
• In support of environmental agreements, TVA will retire the Allen coal-fired units no later than Dec. 31, 2018, replacing them with natural-gas fired combined cycle units.
• Allen combustion turbines burn low-emitting natural gas or ultra-low-sulfur fuel oil.

Sulfur dioxide

Additional historical emission data for combustion turbines will be added when it becomes available.

*Data includes 32 tons from 2000 to 2014 for units that produce less than 25 megawatts and are not required to be reported to the Environmental Protection Agency.

Nitrogen oxides

Additional historical emission data for combustion turbines will be added when it becomes available.

*Data includes 88 tons from 2000 to 2014 for units that produce less than 25 megawatts and are not required to be reported to the Environmental Protection Agency.
