Data Center Record.

Data centers in Montana

Montana has 5 data center sites, 0 buildings where disclosed on the record: 3 proposed and 2 stalled or cancelled. Most are in Silver Bow County (2) and Yellowstone County (2), and records are in 3 of 56 counties. The largest proposal is Quantica Broadview Data Center in Yellowstone County, 5,100 acres (third party estimate); it is proposed since October 16, 2026.

Montana decides case by case. From the state's own rule: NorthWestern Energy filed a large load tariff with the Montana PSC in March to require data centers to pay separate higher rates for energy use, September 8, 2026.

A blank total means no record disclosed the figure; the count without one says how many.

Summed only where a record disclosed the figure; a record with no figure adds nothing and is counted as not disclosed. Water is summed per day and per year separately, as the sources stated it, and never converted. A tax claim given as a range is summed at both ends.

The disclosed totals are in the table above.

No source on file states what any of the 5 tracked facilities in Montana are for. 3 sites not yet verified are named apart and are not in that number.

What each use disclosed

A record that lists several uses counts once under each. Each cell is the sum over the records with that use, disclosed rows only.

No source on file states how any of the 5 tracked facilities in Montana are cooled. 3 sites not yet verified are named apart and are not in that number.
