What TVA is doing about emissions at Paradise
TVA has taken a number of steps to make the efficient generation of power at Paradise as clean as possible:
- Wet limestone scrubbers remove 93 percent of the sulfur dioxide from emissions at all three Paradise units Unit 3 also burns low-sulfur coal to limit SO2 emissions.
- A technology called overfire air reduces oxygen in the furnaces to limit the production of nitrogen oxides that contribute to ozone and acid rain.
- Paradise Unit 2 was the first fossil unit in the TVA system to be equipped with a selective catalytic reduction system that reduces NOx emissions by transforming them into harmless nitrogen and water vapor. All three Paradise units are now equipped with this technology.
- As part of its vision of being one of the nation’s leading providers of low-cost and cleaner energy by 2020, TVA will upgrade the scrubbers on units 1 and 2 at Paradise no later than Dec. 31, 2012.
