Wisconsin got national attention when Microsoft built its Fairwater AI campus in Mount Pleasant. The state sits in MISO, has a cool climate and has utilities planning new generation for data center load. Invariant lists a Wisconsin site with 150 MW of substation capacity built, 80 MW available now and 130 ready acres.

- Wisconsin is in MISO with a cool climate that helps cooling efficiency.
- Microsoft’s Fairwater campus puts about 1.2 million square feet on a 315-acre site.
- Our Wisconsin site has 150 MW built and 80 MW available now on 130 ready acres.
- Built substation capacity is worth more than any map.

Exact locations, the utility documents behind each MW figure and pricing are shared on a call. We also hold sites that are not listed publicly; owners ask for discretion and a site that is shopped everywhere loses value.
Power in Wisconsin
Wisconsin is in MISO. Its utilities are adding generation for data center demand, and large campuses negotiate service directly. A site with a built substation skips the slowest step.Federal Energy Regulatory Commission
Reference campus
Microsoft’s Fairwater campus in Mount Pleasant has three buildings with about 1.2 million square feet on 315 acres and a closed-loop cooling system. It shows the land and cooling plan a large AI campus needs in the state.Microsoft
How to screen a Wisconsin data center site
- Confirm the serving utility and the grid operator, then ask which document backs the MW: a will-serve letter, a load study or a signed agreement.
- Check that the substation has headroom for your load under contingency. Distance to a line is not capacity.
- Screen the county and any city that could annex the site for moratoriums, recent denials and the zoning path.
- Work out usable acres after wetlands, floodplain, slope, easements and setbacks, and reserve room for the substation.
- Kill sites that are already claimed, operating for someone else, contaminated or owned by an environmental liability buyer before spending on parcels.
Invariant runs this screen on every Wisconsin site before an introduction and grades the result A, B or C by power evidence. Tell us your MW and date and we will send the Wisconsin sites that fit, including off-market ones.
