On August 18, as part of a drive to produce more efficient and cleaner power, TVA’s board approved the installation of scrubbers, baghouses, and SCR systems at two coal-fired power plants in Tennessee to reduce sulfur dioxide, particulate matter, and nitrogen oxide emissions at a cost of up to $1.75 billion. In the same meeting, the board gave final approval for the purchase of the Magnolia Combined-Cycle Natural Gas power plant in Mississippi, and the completion of a $4.9 billion nuclear unit in Alabama.
