Vantage MKE1: $8B Port Washington Hyperscale Campus
Status: Pre-Construction / Site Planning (Tax Incentives Disclosed May 2026) | Location: Port Washington, WI
Project Overview
Unveiled through municipal framework transparency and regional tax agreement releases in mid-May 2026, Vantage Data Centers' Port Washington Campus (MKE1) is a monumental $8 billion master-planned megasite. Spanning 1,900 acres just 30 miles north of Milwaukee, the multi-phase deployment is designed to supply an ultimate 1.3 gigawatts of power capacity for frontier AI model training and hyperscale cloud workloads. To secure the development, Port Washington local officials authorized a massive $458 million tax incentive package spread over a 20-year window to construct supporting civil infrastructure. However, the project has attracted considerable public pushback and scrutiny from local residents, environmental groups, and prominent regional commentators who cite severe concerns regarding long-term community ratepayer electricity costs, immense water consumption from local watersheds, and lack of layout transparency. To counter these concerns, Vantage claims the campus will run primarily on zero-emission energy assets, including newly contracted utility-scale solar, regional wind, and on-site industrial battery storage.
