The units to be idled are the Shawnee unit 10 near Paducah, Kentucky; John Sevier units 1 and 2 near Rogersville, Tennessee, and Widows Creek units 1-6 near Stevenson, Alabama.
Two units at the Widows Creek plant will be idled in fiscal 2011, and four other units there will be idled between 2011 and 2015.
The Shawnee unit 10 will be evaluated for possible conversion to biomass fuel, and two units at John Sevier will be idled within the next four to five years.
TVA president and CEO Tom Kilgore said that one of TVA’s key goals is to improve air quality and replacing some coal with other cleaner fuel sources allows a reduction in air emissions including carbon.
TVA provides electricity for utility and business customers in most of Tennessee and parts of Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.
The TVA coal fleet consists of 59 units at 11 plants with a total generation capacity of about 15,000MW.
