New Hampshire data centers, in short
New Hampshire has 17 data centers identified from primary sources, spread across 8 cities and counties and run by 7 operators. The largest concentration is Manchester, with 5 data centers, followed by Portsmouth with 3 and Bedford with 2.
The operators with the most data centers in New Hampshire are FirstLight (11), FirstLight Fiber (1), G4 Communications (1), Consolidated Communications (1), Crown Castle (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 New Hampshire, 4 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.
ISO-NE runs the wholesale power market and the high-voltage grid for all of New Hampshire. 1 statewide measure governing data centers is on record. 1 named project in New Hampshire is delayed, blocked or under challenge.
