AEP Shuts Down Ten Coal-fired Facilities

LCG, June 3, 2015--Last month American Electric Power (AEP) closed ten coal plants located across Appalachia and the Midwest. The electric generating facilities had a combined capacity of 5,588 MW. The plant closings are part of the utility's compliance plan for new Environmental Protection Agency (EPA) regulations, primarily the Mercury and Air Toxics Standard (MATS) rule that began this month.

AEP coal plant closures include: the Kammer Plant (630 MW) in West Virginia ; the Philip Sporn Plant (995 MW) in New Haven, West Virginia; the Kanawha River Plant (400 MW) in Glasgow, West Virginia; the Muskingum River Plant (1,440 MW) in Waterford, Ohio; the Picway Plant (100 MW) near Columbus, Ohio ; the Beckjord Plant (53 MW) in Ohio; the Clinch River Plant (235 MW) in Carbo, Virginia; the Glen Lyn Plant (335 MW) in Glen Lyn, Virginia; the Big Sandy Plant (800 MW) in Louisa, Kentucky; and the Tanners Creek Plant (995 MW) in Lawrenceburg, Indiana.

AEP also plans to retire two other coal-fired units - Northeastern Station, Unit 4 (470 MW), in Oklahoma, and Welsh, Unit 2 (528 MW), in Texas - by the end of 2016. In total, the retirements of these coal fired units will result in a loss of 6,586 MW of electric generating capacity.
