DULUTH, Minn. (AP) -- Minnesota Power says it will stop burning coal at three of its older generators.
The Duluth-based electric utility plans to convert both coal-fired generators at its Laskin Energy Center in Hoyt Lakes to burn natural gas in 2015. The project will cost $15 million.
The company says one of the three coal-fired units at its Taconite Harbor power plant in Schroeder will be retired. Two other coal units at the plant will keep operating with upgraded environmental controls.
In a statement, Minnesota Power also said it intends to add other natural gas-fired generation after 2020, but gave no details.
The Star Tribune (http://bit.ly/XSOjaf) reports the company says its goal is to supply electricity to its 144,000 customers with one-third renewable energy, one-third natural gas and one-third coal-fired generation.
