Riverside Transmission Line Project

American Transmission Co. recently completed an approximately 4.2-mile, double-circuit, 345,000-volt 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 transmission line is needed to connect Alliant Energy’s West Riverside Energy Center to the electric transmission grid. The West Riverside Energy Center, which is expected to begin operation in 2020, is a natural gas-fueled generating station with an integrated solar installation. According to Alliant Energy, it will provide a future supply of cost-competitive and reliable power for its customers and a significant economic investment in the Rock County region.
