This plant generates 90% of the Upper Peninsula's electricity and 12% of the electricity in the Wisconsin Energy system. Half of the plants generating capacity goes to the Empire and Tilden iron ore mines on the nearby Marquette Iron Range.

The plant is owned by Wisconsin Energy and is connected to the grid by numerous 138kV transmission lines and one 345kV line known as the Presque Isle-Plains-Morgan line which runs from Marquette southwest to Iron Mountain and south to Appleton, Wisconsin where it ties into numerous other 345Kv lines going south towards Milwaukee and west towards Wausau, Wisconsin and St. Paul, Minnesota.

In 2006, the plant incorporated a new process for capturing and reducing mercury emissions. [http://www.netl.doe.gov/publications/press/2006/06027-TOXECON_Begins_Full-Scale_Operatio.html]
