Massachusetts at a glance
The largest footprint in Massachusetts belongs to American Tower Corporation, behind 1 tracked facility. TierPoint, LLC round out the most active operators in the state. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.
Geographically, the buildout clusters: Middlesex County leads Massachusetts with 2 facilities and a composite risk score of 6/100. Essex County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.
Most of the Massachusetts fleet we track is already operating, which shifts the public conversation from "should this be built" to scrutiny of the deals already struck — the tax abatements granted, the water permits issued, and the rate impacts now showing up on bills.
We also surface the accountability trail: 2 state bills mentioning data centers and 6 recent news items are tracked for Massachusetts below, pulled from LegiScan and GDELT and refreshed automatically. Legislation is linked to the counties and operators it names; news is classified by community sentiment.
