Opposition and litigation at this site

How the community has taken it

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.
