No one wanted to redevelop this polluted property. Then came AI.

A Colorado-based firm, Viridian Partners, proposes an $8 billion, 800 MW data center campus on a former General Motors brownfield site in Janesville, Wisconsin. The project, supported by city officials as a redevelopment opportunity, faces local opposition due to environmental concerns, electricity demands, and worries about economic dependency. A ballot initiative to stop the project will be presented to voters in November.

As data centers surge, competition grows over who builds Wisconsin’s grid

The Midwest's grid operator, MISO, reversed its decision, reassigning a key eastern Wisconsin transmission project from Blackstone-backed Viridon to American Transmission Company (ATC). This change aims to ensure substations are built in time for a new Port Washington data center, expected online by early 2028. The decision has implications for Wisconsin ratepayers, who may bear a larger share of the $1.3 billion buildout cost for the data center's power supply.
