Ark Green Bay Data Center Campus is an operating Ark Data Centers data center facility in Greenville, Wisconsin. Ark's operating Green Bay-area facility plus its directly adjacent 24.5-acre expansion campus. Current operating facts remain distinct from the multi-phase expansion envelope. The retrofit records future campus power capacity: 20 MW; conditioned space: 7,192 sq ft; colocation space: 5,000 sq ft; site area: 24.5 acres. Utility service, UPS, standby generation, cooling, facility power and IT load are kept in their source-defined scopes rather than collapsed into one capacity number. Where reliable public evidence for ownership, project financing, permitting, tenants or water arrangements was not established, Cartis records the research gap explicitly instead of inferring a fact.
