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).

GridWatch is not yet tracking a named project in New Hampshire. That is a gap in our coverage, not evidence that nothing is proposed — most projects surface first in a zoning agenda, weeks before any reporting.

As of August 2026 (2m ago) · changes weekly — re-check before citing

Illustrative rather than exhaustive — dozens of localities churn weekly, and this tracks the ones we have read a source for. **Each row carries its own provenance.** Rows showing a verification date link to the ordinance, the enacting body's own page, or a datable report of the vote, and were read on that date. Rows marked *unverified* came from bulk compilation and have not been checked against a primary source — the locality, the year, and the status may all be off. Verify one of those with the town clerk before citing it as precedent. **Expiry is derived, not asserted.** A row with a documented end date flips to *Expired* on its own once that date passes. A time-limited moratorium whose start date was never documented keeps showing as enacted — that is a known gap, not a claim that it is still in force. Moratoriums are also routinely extended, so an expiry date is the earliest it could have ended, not proof that it did.

Already built

3Every data center already built in New Hampshire

GridWatch does not yet track a named hyperscale campus in New Hampshire, but that does not mean the state has none. DataCenterMap keeps a public directory of existing facilities — street addresses included — for New Hampshire.

Browse the New Hampshire directory →

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.

Air & environmental permits: New Hampshire DES — Air Resources Division

No searchable register. New Hampshire does not publish a permit database you can query. A public-records request to the agency is the only route to the file.

Grid interconnection queue: ISO New England

A routing hint only — several states are split between markets, and the serving utility is the only authority on which queue a given site is in.

These are places to look, not evidence that anything has been filed. Links were checked on 2026-08-21; search links are queries, not records.
