Minnesota Power Completes Major Environmental Improvement Project at Boswell Energy Center

A three year environmental improvement project has wrapped up at Minnesota Power’s Boswell Energy Center. 

The project will reduce emissions and generate electricity more cleanly and reliably. 

The upgrade means that Boswell is reducing mercury emissions by 90 percent and significantly reducing emissions of sulfur dioxide and particulates, meeting all state and federal regulations.  

Unit 4 is Minnesota Power’s largest coal-fired generating unit, capable of producing 585 megawatts. 

The Boswell project cost around $260 million.  

“The new state-of-the-art technology at Boswell 4 will make the generating unit among the cleanest and most efficient in the nation while helping to preserve the reliable and affordable power our customers expect,” said Al Hodnik, ALLETE Chairman, president and CEO. 

Over the past decade, Minnesota Power has invested more than $600 million to cut emissions across the system.
