The largest concentration is Portland, with 5 data centers, followed by Brunswick with 3 and Bangor with 2. The operators with the most data centers in Maine are FirstLight (7), CENTRA Digital Interconnect (1), Consolidated Communications (1), NNENIX (1), University of Maine System (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 Maine, 3 publish a floor area and 1 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. ISO-NE runs the wholesale power market and the high-voltage grid for most of Maine. 2 statewide measures governing data centers are on record, alongside 1 local pause. 1 named project in Maine is delayed, blocked or under challenge. The list ## Maine data centers by city Every data center identified in Maine, grouped by the city or county it stands in, 12 of them across 5 places.
