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.

Gardner Park-Central Wisconsin

The Public Service Commission of Wisconsin granted approval for this project in June 2006. The line was placed in service in 2009.

This line supports the electrical output of a new 500-megawatt generator at Wisconsin Public Service Corp.’s Weston Power Plant south of Wausau. The transmission system that has carried electricity from the Weston Plant since the 1950s was inadequate to deliver the increased output from the new generator. Both the plant expansion and the new line were needed to serve the increase in electricity usage, which had almost doubled in the last 30 years.

This approximately 50-mile line will interconnect with a new 345-kilovolt line (Morgan-Werner West Project) to link the existing Morgan Substation, southwest of Oconto Falls, to a new substation called Werner West in the New London area.
