Minnesota Power said Wednesday that it will stop burning coal at three of its older generators.
The electric utility serving the Iron Range and central Minnesota said it plans to convert both coal-fired generators at its Laskin Energy Center in Hoyt Lakes, Minn., to burn natural gas in 2015. The project will cost $15 million, the utility said.
One of the three coal-fired units at the utility’s Taconite Harbor power plant in Schroeder, Minn., will be retired, the company said. Two other coal units at the plant will keep operating with upgraded environmental controls.
