- Operational · 3A mapped building in OpenStreetMap, a Texas Comptroller program registration, or news reporting the site as running.
- Under construction · 0News reporting construction underway at the site.
- Planned · 0A TCEQ air permit on file with no mapped building yet, or a project announced in the news. Permits come before buildings, so this is the early-warning state.
- Paused · 0News reporting the project on hold.
- Inactive · 0News reporting the facility closed or the project cancelled.
- Registered, status unknown · 0In a state registry under a program that says nothing about construction (no air permit, no mapped building). Unknown is the answer, not a guess.

How this registry is counted
One row is one campus. OpenStreetMap maps individual buildings, so buildings within 400 meters of each other fold into a single facility; a facility found by two sources within 400 meters of each other is one row that lists both. Coordinates are never altered — a merged row keeps the mapped building’s position.
Status is inferred from what each source states and nothing more: a mapped building or a Texas Comptroller registration means the facility exists; a TCEQ air permit with no building yet means it is permitted, not built; a registry entry under a non-air program says nothing about construction, and the row says so. No source here confirms anything on site.
State and county come from the U.S. Census TIGER/Line county boundaries the facility point falls inside. Every count on this page is computed from the same registry file — nothing is typed in by hand.
Questions
How many data centers are in Massachusetts?
As of the September 18, 2026 registry snapshot, Massachusetts has 3 facilities: 3 operational. These are facilities recorded by public sources Geolocity mirrors; a site no source has mapped or registered is not counted.
Which Massachusetts counties have the most data centers?
Middlesex County (2), Essex County (1). Facilities sit in 2 counties in total; each county has its own page with a map and the facility list.
What does "planned" mean on this page?
A facility with an air permit on file (TCEQ, Texas only) or a public announcement, and no mapped building yet. Backup-generator air permits are issued before construction, which is why they read as early warning — and why a planned row is evidence of intent, not a promise that anything gets built.
