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

  1. Proposed

    TAC Data Centers announced Project Cardinal, a hyperscale campus of about 2 million sq ft that would need up to 600 MW, on a 569-acre site just outside Great Falls' northeast boundary between Malmstrom AFB and the Missouri River.

    Underlying source
  2. Cancelled

    TAC released its option to lease the 569 acres. NorthWestern Energy's power timelines did not fit the project.

Source notes

The pin is the Great Falls city centroid, not the parcel. The site was 569 acres adjacent to AgriTech Park, north of Malmstrom Air Force Base, outside city limits. The reported investment was $1-1.5 billion. Job figures are the low ends of the reported ranges: 1,500-2,000 construction and 150-200 permanent.
