Vantage Port Washington Campus (Lighthouse)

Vantage's Lighthouse campus sits on 672 acres in Port Washington, Wisconsin, about 30 minutes north of Milwaukee. The operator has announced 902 MW of planned critical IT load across four single-story data centers totaling 2.5 million sq ft, with completion scheduled for 2028 — making it, by disclosed capacity, the largest of Vantage's announced North American campuses. Rack densities are designed up to 1.4 kW/sq ft, and cooling combines conventional air-cooled chillers with liquid-to-liquid systems built to support GPU-class workloads. Power comes from We Energies, with Vantage citing 70% zero-emission generation (solar, wind and battery storage) and the remainder matched through renewable purchases for a 100% annual match. The campus runs N+1 mechanical and electrical redundancy, three meet-me-rooms and one point of entry per building, and is pursuing LEED certification rather than holding it yet. Vantage also cites a commitment to plant more than 2,000 native trees on the site as part of its sustainability program.
