Arizona: data centers & your electric bill
The numbers residents cite at hearings — grid, water, and regulator contacts for Arizona, from the free GridWatch toolkit.

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).

Pushback already happening in Arizona
| Where | Level | Status | Note | Source |
|---|---|---|---|---|
| Arizona (tax incentives) | State | Enactedexpires 2029-06-30 | HB 4168 — 3-year moratorium on new data center sales tax exemption applications, signed Jun 13. Saves ~\$57M. Developers submitted 113 applications in the 2 weeks before the pause (nearly as many as in the previous 13 years combined) | Source read 2026-08-13 |
| Pima County | Local | Proposed | Board voted 3-2 to direct staff to draft 120-day moratorium on data center approvals. Prompted by opposition to 'Project Blue'. Formal approval still needed. Permanent ordinance expected fall 2026 | Source read 2026-08-13 |
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.
Case studies
Mesa, AZ — Zoning rules instead of a moratorium: setbacks, height caps, sound study
With 15 data centers built, approved or proposed on roughly 1,500 acres in six years, Mesa's council introduced zoning controls 6–0 and adopted them in July 2025. Data centers are now allowed only where the council specifically authorises a Planned Area Development overlay on industrial land, and each must sit at least 400 feet from residential, stay under 60 feet tall, screen its mechanical equipment, and submit a sound study. Water cooling was argued in council — Councilwoman Jenn Duff pushed to restrict it during drought — but did not make it into the adopted rules. Worth reading as a list of what a council will grant without a moratorium, and what it won't.
Known data center campuses in Arizona
| Operator | Location | Tenant | Filing LLC |
|---|---|---|---|
| Meta | Mesa | Meta | Codename shells: Greater Kudu, Raven Northbrook, Stadion, Wobniar, Pinnacle Mountain |
| Microsoft | Goodyear (Greater Phoenix) | 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 Arizona
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 Arizona.

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.
