American Transmission Co. projects

Project website for a Wisconsin-based company that owns and operates the high-voltage electric transmission system that powers communities in portions of the Upper Midwest.

The Morgan-Central Wisconsin-Werner West line was built to relieve congestion on facilities in and north of Green Bay, resulting in additional transfer capability and greater electric reliability for the area. In addition, it provides capability for transmission service for a new power plant in the Wausau area.This line intersects another new 345-kilovolt line (Gardner Park to Central Wisconsin Project) that would link a new substation, Gardner Park, located just south of the existing Weston Power Plant to the Central Wisconsin Substation in central Shawano County.

Northeastern Wisconsin and the Upper Peninsula of Michigan are served electrically by 345- and 138-kilovolt transmission lines that are some of the most constrained in the ATC system. These constraints have limited ATC’s ability to move power in and out of the Upper Peninsula, and have caused overloading on other parts of the electric system.
