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.

Brodhead-South Monroe Project

American Transmission Co. will soon begin rebuilding the 18-mile, 69,000-volt electric transmission line that connects the Brodhead Substation and South Monroe Substation in Monroe. The age and condition of the existing line, which was built in 1950, necessitated the rebuild.

The new line will make a vital improvement in the reliability of the electric transmission system serving the area and will help ensure that the south central Wisconsin area is served by a reliable electric delivery system in years to come. The voltage of the line will not change, but the replacement structures and line will be designed to accommodate increased electric demand and to support growth.

The new line will follow the route of the existing line, and the work will involve installing new poles, wires and insulators.
