US Signal WI02 Madison Data Center

PRJ-1246 · Site · Fitchburg, Wisconsin, United States

Record last updated Oct 28, 2026

Scope and capacity

US Signal WI02 Madison Data Center is an operating US Signal data-center facility in Fitchburg, Wisconsin. US Signal's WI02 facility at 5515 Nobel Drive; infrastructure ratings are not operating IT load. The retrofit records utility feed capacity: 9000 kVA; backup generation capacity: 4500 kW; ups capacity: 6000 kW; cooling capacity: 1510 tons. 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.

Headline: 0.6 MW Planned critical IT

Numbers refer to their stated physical boundaries and are not added together. Source dates, claim dates and record updates have different meanings. Missing dates and locators are not inferred.
