Proposed-site record

Driftless Area Data Center

The proposed Cassville-area campus fell apart after local opposition and zoning action. Public reporting supports a prospective 400–500 MW power estimate and a two-year data-center restriction, but no facility-specific water, wastewater, utility-service, energized, generation, or IT-load record was found.

This panel tracks what the facility is for without assuming that every project is AI training, inference, or cloud capacity.

No source-backed workload, customer, hardware, or training/inference allocation is attached to this record yet.

Workload classification remains unknown in the reviewed record.

Public Money

Source review September 9, 2026: Wisconsin Watch reports an estimated $5.5 million in annual property-tax income for a proposed $2 billion project. That is a projected local revenue benefit, not spending, a subsidy award, or proof of the dataset's reported project cost; public incentive records remain unresolved.

Water

Source reviewed September 9, 2026: Wisconsin Watch's reporting on the proposed Cassville-area campus describes community concern about water and environmental impacts but does not disclose a cooling method, water source, withdrawal permit, service quantity, or wastewater capacity. Those facility-specific records remain unresolved; a closed-loop or waterless design must not be inferred from the proposal's collapse.

Power

Source reviewed September 9, 2026: Wisconsin Watch reported a developer had been scouting the area and quoted Grant County economic-development leadership estimating the prospective data center would require about 400-500 MW. The Cardinal-Hickory Creek transmission line is cited as a location attraction, but no utility agreement, interconnection approval, energized service, generation record, or data-center IT-load disclosure was reviewed. Cassville later adopted an ordinance restricting data centers for up to two years. The dataset's 400 MW remains an unverified prospective project/power estimate, not confirmed requested, approved, energized, generation, or IT-load capacity.
