Wyoming data centers, in short
Wyoming has 41 data centers identified from primary sources, spread across 11 cities and counties and run by 10 operators. The largest concentration is Cheyenne, with 27 data centers, followed by Casper with 3 and Sheridan with 2.
The operators with the most data centers in Wyoming are Advanced Communications Technology (9), Microsoft (2), Mountain West Technologies (2), Prometheus Hyperscale (2), fifteenfortyseven Critical Systems Realty (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 Wyoming, 3 publish a floor area and 5 publish a power figure, 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 Wyoming, so each utility and the state commission set interconnection terms. No statewide measure governing data centers is on record.
