Vantage Data Centers: Port Washington (Lighthouse) Data Center Campus – Building 4

Building 4 is part of the Port Washington (Lighthouse) Data Center Campus, a landmark AI-focused development in Wisconsin designed to meet unprecedented demand for next-generation compute infrastructure. Strategically located in the Badger State near Milwaukee, the campus offers hyperscale-ready capacity, advanced cooling technologies, and high-density power infrastructure to support AI, HPC, and large-scale cloud deployments. The campus spans approximately 670 acres and is planned to deliver 902MW of critical IT load across four, one-story data centers once fully developed, totaling approximately 2,500,000 square feet. Building 4 benefits from this master-planned hyperscale campus architecture, incorporating high-capacity electrical systems, diverse connectivity pathways, and scalable mechanical infrastructure.

Designed for next-generation AI workloads, the campus supports rack densities up to 1.4kW per square foot, accommodating both traditional and liquid-cooled high-performance deployments
