Foundry Ridge Energy Center
Foundry Ridge Energy Center is a proposed 324 megawatt natural gas peaking plant in the Town of Darien in Walworth County, WI, developed by Invenergy. If approved, construction will begin in late 2026/early 2027, and the project will be operational in 2028.
Peaking plants operate only during times of high electric demand, when baseload isn’t enough, providing reliable power to maintain a stable and responsive electric grid.
