News release: Work to start along Michigan’s Upper Peninsula

Laurium Rebuild will improve electric reliability in Houghton County

Kingsford, Mich. – American Transmission Co. will soon begin reconstruction of the existing transmission line that runs between the Atlantic Mine Substation, located in Adams Township, and the Osceola Substation, located in Calumet Township.

“The upgraded transmission line will improve electric reliability in Michigan’s Upper Peninsula,” said Brett French, ATC customer relations. “We will do our best to inform landowners of the impact of our work, while keeping disruptions to a minimum as we complete the project.”

During the project, the existing transmission facilities will be replaced with new steel poles, insulators and wires along and within the existing transmission right-of-way corridor. ATC will also upgrade the substations in this area.

The affected communities include the City of Hancock, and the Townships of Adams, Quincy, Franklin, Osceola and Calumet. All are located in Houghton County. These communities may experience heavy truck traffic from time to time as equipment and materials are mobilized to the area to support this project.

ATC will start the work in August. This project should be complete, and the facilities placed in service by the end of May 2008.

This project, estimated to cost approximately $9 million, is another example of ATC’s ongoing commitment to the Upper Peninsula.
