Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.
Reported lifecycle history
- Proposed
Balloonist LLC filed an annexation petition and I-1 rezoning for a ~324-acre site on County Highway B (Town of Red Cedar)
Underlying source - Proposed
Menomonie City Council approved annexation and I-1 rezoning 8-3; rezoning is not a building permit
Underlying source - Proposed
Mayor Knaack declared the project 'on pause'; TID/development-agreement talks ended; Balloonist subsequently purchased the land
Underlying source - Proposed
City Council adopted a new I-4 Data Center Industrial District ordinance with stricter parameters, effectively requiring Balloonist to reapply
Underlying source - Proposed
Mayor Crowe: city still refining the I-4 ordinance, draft to be introduced Aug 3 2026; Balloonist retains the land
Underlying source
Source notes
End operator undisclosed behind Balloonist LLC (a Delaware foreign LLC). Multiple outlets note Balloonist's Delaware address and registered agent match prior Meta data-center SPV patterns, but no source names Meta or any operator - recorded as undisclosed. A council member said the end user is 'one of the top tech giants' without naming them. The record is listed as proposed rather than permitted: the original I-1 rezoning was superseded by a January 2026 I-4 ordinance; no building permits were ever issued. Proposed investment up to $1.6B and 50-75 FTE jobs are developer projections (not recorded as firm fields). No MW capacity disclosed. Site: ~324 acres along County Highway B (annexed from Town of Red Cedar Aug 2025). Coordinates are the Menomonie centroid. The likely AI-specific classification rests on hyperscale scale + 'tech giant' attribution, not an explicit AI-workload statement.
Balloonist LLC confirmed working with Xcel Energy and the WI Public Service Commission on supply/grid; no MW load or substation figure disclosed.
