Massachusetts

## Massachusetts data centers, in short

Massachusetts has 53 data centers identified from primary sources, spread across 21 cities and counties and run by 32 operators. The largest concentration is Boston, with 6 data centers, followed by Springfield with 6 and Waltham with 5.

The operators with the most data centers in Massachusetts are Crown Castle (4), Lumen (4), FirstLight (4), Cogent (3), Equinix (3). 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 Massachusetts, 22 publish a floor area and 10 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 all of Massachusetts. 1 statewide measure governing data centers is on record, alongside 1 local pause. 3 named projects in Massachusetts are delayed, blocked or under challenge.
