Madison, Wisconsin – American Transmission Co. this week submitted an application to the Public Service Commission of Wisconsin for the 345,000-volt Riverside Transmission Line Project. Project plans include an approximately 4- to 4.5-mile, double-circuit transmission line from a planned new substation near the Alliant Energy West Riverside Energy Center to an existing 345-kV transmission line in the Town of Beloit.

The project 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.

“We have identified a preferred and an alternative route for the project. If the project is approved, the Public Service Commission of Wisconsin will select and order only one route to be built,” said ATC Project Manager Mark Sanzenbacher.

If the project is approved by the PSC, construction is expected to begin in 2018 to meet an in-service date of 2019. Application materials and other documents associated with the proposed project are available at The docket number for this project is 137-CE-186.
