Energy company Edison International announced, that its subsidiary Midwest Generation will close two of its major Illinois coal-fired power plants ahead of the deadline imposed by new emissions rules, according to The Chicago Tribune.
The two coal-fired power plants, the Fisk and Crawford generating stations, are now scheduled to be closed this September.
The older power plants were already scheduled to be shut down in 2018, when new rules laid out by the U.S. Environmental Protection Agency will require all coal-fired generation to meet strict emissions standards, but Chicago Mayor Rahm Emanuel has been pushing for their closure well before that date.
The two coal power plants provide a combined 858-megawatts of baseload generating capacity, along with 214 megawatts of peaking capacity.
Midwest Generation holds a total of 5,943 megawatts of generating capacity, including a large amount of coal, but the company's plans for these power plants remain unclear, given the $628 million in upgrades that will be necessary to meet the new standards.
