TVA to retire 18 coal plants April 24, 2011 : 1:13 PM

North Carolina forces the Tennessee Valley Authority to take action:

“The state has settled a 5-year-old lawsuit with the Tennessee Valley Authority over emissions from its coal-fired plants.”

“The deal was part of a larger settlement with the U.S. Environmental Protection Agency over TVA violations of the clean air act at 11 of its coal-fired plants in Alabama, Kentucky and Tennessee.”

“The settlement requires the TVA to invest an estimated $3 billion to $5 billion on new and upgraded pollution controls. It must reduce emissions by retiring at least 18 of its 59 coal units and installing and continuously operating emission-control equipment on almost all of the remaining units.”
