Racine County, WI

Microsoft Project Nova (Caledonia)

Microsoft (filed as Dewberry (for Microsoft)). Withdrawn.

Microsoft sought to rezone 244 acres near County Line Road and Highway 32 in Caledonia, across from the We Energies Oak Creek power plant, for what would have been a third Racine County data center under the code name Project Nova. More than 2,000 residents signed a petition against it, and Microsoft withdrew the proposal on October 8, 2025, saying it would look for another site in the area.

What it would mean nearby

We Energies is asking the commission for a 9.3% residential increase (We Energies general electric and gas rate case for 2027 and 2028 (docket 5-UR-112)). On a $160 monthly bill that is about $13 to $17 a month. This tariff does not change home electric rates by itself, but it is meant to make large new data centers pay the full cost of the power plants and lines built to serve them instead of spreading those costs across everyone's bill. Transmission upgrades like this are typically billed to every electric customer in the state through transmission charges, not just to the data center that made the new line necessary, which is why the cost allocation question matters for ordinary bills even outside the four counties involved.
