Opposition and litigation at this site

Yes.

How the community has taken it

Reception is a sourced signal, not an editorial judgment: opposed means documented, organized local opposition is the dominant signal on record.

Power and water

Alliant Energy confirmed as utility. QTS proposed enabling ~750 MW of new renewables on Alliant's grid via RECs - a grid-level commitment, not the facility's power draw. Facility IT load never disclosed.

QTS stated the campus would use water-free cooling with no cooling-water consumption or impact on the Yahara Watershed.

Notes on the record

CANCELLED: QTS withdrew Jan 28-29 2026 after DeForest found the proposal not feasible and the Village Board signaled a 7-0 rejection of the required annexation; WI DOA found the 1,572.5-acre annexation petition not in the public interest. Active footprint was 650 acres (five buildings). Capacity omitted: no source discloses facility IT load; the 750 MW figure was a grid renewable-energy-credit commitment via Alliant, not the campus draw. INVESTMENT OMITTED: the $12B figure is secondary press only (QTS said 'multibillion-dollar') and unrealized. Projected 5,000+ construction and 'hundreds' of permanent jobs were never realized (project cancelled). The $50M community commitment was a QTS-to-county pledge, not a government subsidy. Coordinates are the DeForest centroid.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Power capacity in megawatts
  • Tax abatements or other public subsidy
  • Permanent jobs promised
Which document closes each gap
Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
