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).

As of August 2026 · 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.
Known data center campuses in Michigan
| Operator | Location | Tenant | Filing LLC |
|---|---|---|---|
| Microsoft | Southeast Michigan | Microsoft | Project-name / generic 'Holdings LLC'; less consistently codenamed |
⏳ No verification date recorded · changes over months · Source: Operator ownership & filing-LLC naming patterns — compiled from operator releases and county filings, then checked against SEC EDGAR full-text search. Composite, not a single citation: look the entity up yourself before naming it in a filing
Each row carries its own attribution level — first-party rows come from the operator's own site, but colocation and REIT ownership was compiled from trade press and never passed an independent fact-check. Check the attribution column before citing a row.
Every data center already built in Michigan
The campuses above are the ones GridWatch tracks by operator and filing LLC. For the full inventory — street addresses of every existing facility, including the smaller colocation and network sites — DataCenterMap keeps a public directory for Michigan.

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.
