Three new transmission lines that are estimated to cost around $2.2 billion will cross through Wisconsin under a large expansion approved by the Midwest grid operator that’s designed to facilitate the clean energy transition.

The board for the Midcontinent Independent System Operator signed off on a $10.3 billion portfolio of 18 transmission projects for the Upper Midwest on July 25. The lines are expected to support 53 gigawatts of renewable energy and provide between $23 to $52 billion in benefits as utilities retire aging coal plants. Projects in Wisconsin are slated to start coming online as early as 2028.
