Wisconsin electrical utility We Energies has started construction on three renewable energy and battery storage projects in Wisconsin, with around half of their combined capacity earmarked to supply a major AI data center campus in Port Washington.

The projects comprise a 150MW solar and 50MWh battery storage project in Rock County, a 110MW wind farm spanning Iowa and Grant counties, and a 75MW battery energy storage facility in Walworth County. The projects are expected to be completed by the end of 2027.
Chicago-based Invenergy will develop the facilities before transferring ownership to Wisconsin utilities. We Energies will hold the majority ownership stake, with the remainder shared between Madison Gas & Electric and Wisconsin Public Service.
Approximately 50 percent of the generated capacity of each of the projects has been allocated to the under-development $15 billion Port Washington campus being developed by Vantage Data Centers, Oracle, and OpenAI.
