Three coal-fired power plants in West Virginia have shut down operations.
Media outlets report that Appalachian Power's Kanawha River Power Station at Glasgow, the Kammer Power Station near Moundsville and the Phillip Sporn Power Station at New Haven were closed Sunday.
Appalachian Power had announced in 2011 that it planned to close the plants, along with three coal-fired plants in Virginia, Ohio and Indiana. The company had said it would be cost-prohibitive to equip them to comply with new federal emission standards for mercury and other hazardous air pollutants. Another coal-fired plant inVirginia is being converted to natural gas.
In March, the company sent notices regarding the West Virginia plant closures to the state and to employees.
