Montana data centers, in short
Montana has 20 data centers identified from primary sources, spread across 9 cities and counties and run by 10 operators. The largest concentration is Billings, with 7 data centers, followed by Helena with 3 and Missoula with 3.
The operators with the most data centers in Montana are iConnect Montana (8), Vision Net (4), Konceptio Data Services (1), State of Montana (1), Johnson Services (1). Colocation and interconnection providers appear most often because they publish building-level detail; hyperscale campuses appear where the operator or the county names the individual buildings.
Not every operator discloses size. In Montana, 1 publish a floor area, and each figure is shown against the data center it belongs to rather than added into one number. They are not the same measurement: one operator states the floor area of a single building, another the full capacity of a campus it has only announced.
NON-RTO There is no RTO or ISO market in most of Montana, so each utility and the state commission set interconnection terms. No statewide measure governing data centers is on record, alongside 1 local pause.
