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 sulfur dioxide from emissions at all three Paradise units. Unit 3 also burns low-sulfur coal to limit sulfur dioxide emissions.
- A technology called overfire air reduces oxygen in the furnaces to limit the production of nitrogen oxides.
- 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 to reduce nitrogen oxide emissions by about 90 percent.
- 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 performance of the scrubbers on Paradise units 1 and 2 by Dec. 31, 2012.
