The largest concentration is Stamford, with 9 data centers, followed by Hartford with 3 and Norwalk with 3. The operators with the most data centers in Connecticut are Lumen (8), CyrusOne (3), Cloudpath (3), Crown Castle (2), Encompass Digital Media (2). 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 Connecticut, 5 publish a floor area and 4 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 Connecticut. 1 statewide measure governing data centers is on record, alongside 1 local pause. 2 named projects in Connecticut are delayed, blocked or under challenge.
