Minnesota Power (MP)

MP Overview

Minnesota Power (MP), based in Duluth, Minnesota provides electric services to around 144,000 retail customers, and about a dozen large industrial enterprises in northeast Minnesota. The majority of the power at Minnesota Power is generated from low-sulfur, low-mercury coal from the Powder River Basin. Faced with ever-more-stringent emission regulations at the state and federal level, the company initiated a $240 million project in 2006 to reduce emissions from the 350 megawatt Boswell Energy Center Unit 3, company’s second largest generation unit.
