Vantage Data Centers Lighthouse Campus

High-priority Lighthouse campus. Current company, DNR, and PSC records distinguish Vantage's 902 MW critical-IT claim, utility/transmission infrastructure, planned water service, and closed-loop cooling from the dataset's broader unverified range; customer allocation and measured operating use remain unresolved.

Compute Workload

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

Undisclosed / unknownUnknown

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

No public funding record attached yet. Local subsidy, tax-abatement, land, bond, and utility records need follow-up.

Water

Source review September 9, 2026: Vantage describes a closed-loop chilled-water design and near-zero WUE as company claims. Wisconsin PSC's July 2026 application for a 4.2-mile, 16-inch water main identifies applicant-stated demand of 22,000 gallons per day and a 3,500-gallons-per-minute fire-flow target; the project would provide a redundant supply to Vantage's private water system. These are planned/service figures, not measured consumption or wastewater volume.

Power

Vantage says We Energies supplies the Lighthouse campus with multiple feeds and renewable-energy matching; Wisconsin DNR records the separate sewer-service and environmental-review process. The dataset's 1,300-3,599 MW remains unverified as requested, approved, energized, generation, or data-center IT-load capacity.
