Electric transmission line connecting West Riverside Energy Center to the grid placed in service

Line is part of an integrated electric system serving customers in the region

Madison, Wis. – American Transmission Co. recently energized the approximately 4.2-mile, 345,000-volt Riverside transmission line. Project work included building a new substation near the Alliant Energy West Riverside Energy Center and connecting a new double-circuit transmission line to an existing 345-kV transmission line in the Town of Beloit.

The line is needed to connect the expanded West Riverside Energy Center to the electric transmission grid. The West Riverside Energy Center will include a natural gas-fueled generating station with an integrated solar installation. The estimated cost of the transmission line project is $42 million.

“We’d like to thank members of the public and residents for their cooperation as we worked to construct the transmission line and substation,” said ATC Project Manager Mark Sanzenbacher. “Crews are expected to complete restoration activities in the area this spring.”
