LG&E and KU Announce the Retirement of the Coal-fired Green River Generating Station

LCG, October 2, 2015-Louisville Gas and Electric Company (LG&E) and Kentucky Utilities Company (KU), subsidiaries of PPL Corp., yesterday announced the retirement of the coal-fired Green River Station, located in western Kentucky. The retirement of Units 3 and 4 on September 30 completes the least cost compliance plans announced by the utilities in 2011 to retire 800 MW of coal-fired generation to meet the environmental mandates issued by the Environmental Protection Agency (EPA).

The Green River facility began operations in 1950. With increasing environmental regulations and additional required emission controls, Units 1 and 2 were retired in 2004, reducing the plants capacity from 263 to 163 MW. Units 3 and 4, which were originally scheduled to retire in 2016, are retiring now due to early completion of regional transmission projects to enhance electric reliability for the region and grid as a whole.
