As of July 2026 (3m ago) · changes over months · Source: U.S. Data Center Power Map by State — ElectricChoice.com compilation (updated July 2026; CC-BY 4.0). Underlying load research: LBNL 2024 US Data Center Energy Usage Report; rates: EIA
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 (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.

4Known data center campuses in Mississippi
| Operator | Location | Tenant | Filing LLC |
|---|---|---|---|
| Amazon (AWS) | Madison County | Amazon (AWS) | Vadata, Inc. — AWS's build/operating entity on many permits |
| Amazon (AWS) | Warren County (Vicksburg) | Amazon (AWS) | Vadata, Inc. — AWS's build/operating entity on many permits |
⏳ 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.
5Every data center already built in Mississippi
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 Mississippi.

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.

7Where the Mississippi paper trail lives
Air & environmental permits: Mississippi DEQ — Air Division
No searchable register. Mississippi 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: MISO (Midwest & Gulf)
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.
