American Electric Power announced Thursday that it will be closing its coal-fired power plant in Beverly, Ohio, making it the third plant to announce its closing since Obama gave a new energy speech on June 25. AEP originally planned to shut down four of its five power plants and convert the fifth into a natural gas-powered plant. That plan is no longer in place.

“Due to the cost of compliance with environmental regulations and current market conditions, AEP has determined that it is unlikely to make the capital investment to refuel the unit,” the company said in its announcement.
