Facility counts vary by directory because each one draws the boundary differently — DataCenterMap lists 44 in Alabama where this table says 35, since it counts small network rooms alongside hyperscale campuses. Cite the TWh figure rather than the facility count when you can; it is the number that speaks to grid impact. Underlying load research is LBNL-2001637 (Dec 2024).

Every data center already built in Massachusetts
GridWatch does not yet track a named hyperscale campus in Massachusetts, but that does not mean the state has none. DataCenterMap keeps a public directory of existing facilities — street addresses included — for Massachusetts.

Two caveats before you cite it at a hearing: it lists facilities that already exist, so a newly proposed campus will not appear; and it counts a small network room the same as a hyperscale campus, so the facility count is not a measure of power draw or community impact.
