AI data center in DeForest, WI, United States: cancelled.

Status: Cancelled

QTS proposed a $12 billion data center campus on about 1,600 acres of farmland in the Town of Vienna, to be annexed into the village of DeForest north of Madison. The Town of Vienna rejected a support agreement in November 2025 and the state Department of Administration opposed the annexation. On January 30, 2026, QTS told the village it was suspending the project and asked to withdraw its applications, and the village board then rejected the annexation (Wisconsin Watch, August 4, 2026). No capacity was published. Source: Wisconsin Watch via Urban Milwaukee, 2026-08-04.
