Cumberland Fossil Plant

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

Wet limestone scrubbers remove 95 percent of sulfur dioxide from the plant’s emissions.
Both units are equipped with selective catalytic reduction systems completed in 2004 and low-NOx burners that reduce nitrogen oxide emissions during the May to September ozone season by more than 90 percent.
