Google Project Loon (Hermantown)
Hermantown, St. Louis County, MN
Google Project Loon (Hermantown) is a planned data center in Hermantown, MN, with Google (built by Mortenson) named as the developer. Google-confirmed ~$650M hyperscale data center ('Project Loon'), originally 4 buildings/1.8M sq ft, scaled back to 3 buildings/1.66M sq ft, on 200-400 acres in SW Hermantown adjacent to Midway/Solway Townships; reported capacity in the 300-600MW range, no single confirmed figure. Google pledged to fund 700MW of new clean energy (300MW wind + 400MW storage) and ~$130M of public water/sewer/road infrastructure. City Council voted 4-0 to rezone ~200 acres (first step) but tabled tax-break/development-agreement votes in May 2026 amid opposition from the Minnesota Center for Environmental Advocacy and local groups.
