Data center moratoriums and restrictions in Arizona (2026)

Statewide actions in Arizona

• Arizona: incentive rollback, in force, July 1, 2026Three-year pause: the Arizona Commerce Authority may not accept applications for, or grant tax relief to, any new computer data center from July 1, 2026 through June 30, 2029. Existing certificates unaffected, and the provision self-repeals July 1, 2029. The Governor's office estimates about $57M in savings over the window (an administration estimate, not a formal fiscal note). ACA received 113 applications in the final two weeks before the window closed. Instrument: HB 4168 / SB 1861 (Laws 2026, Ch. 140). Source: Arizona Legislature, SB 1861/HB 4168 as-enacted fact sheet.

Local actions in Arizona

Blocked or delayed projects in Arizona

• Project Blue: Tucson's council voted 7-0 on August 6, 2025 to rescind the planned annexation and development agreement, but the 290-acre site, county-owned land north of the Pima County Fairgrounds, was never inside the city, and the developer's June 2025 purchase agreement with Pima County predated the vote. Beale waived the annexation and city-water closing conditions, supervisors approved a revised deal 3-2 in December 2025, the sale closed December 24, 2025, and construction began April 24, 2026 under county-only approvals with state-permitted groundwater, reportedly scaled back and with Amazon stepping away as end user. The project never moved. The vote removed the city from the deal, along with its development agreement, reclaimed-water arrangement, and tax share. An opponents' lawsuit challenging the approval process was dismissed in April 2026.
• Project Range: Tract withdrew its $14B, roughly 1,000-acre Project Range rezoning in unincorporated Maricopa County in May 2024 after objections from Goodyear and Buckeye; in August 2024 it closed on a 2,069-acre replacement site near Buckeye Municipal Airport, a $20B, up-to-1.8GW park backed by Buckeye's mayor. Utility planning and early infrastructure preparation were reported progressing into 2026. Neither the county planning commission nor the Board of Supervisors ever voted on the original applications, which a county spokesperson confirmed were withdrawn and closed.

What one campus pays a local government

The parent piece's calculator puts a single large campus at $2M to $90M a year in local revenue, depending on the tax regime and abatements. The reference campus (Project Blue scale: $3.6B of capital, 286 MW) pays about $157M to local governments over 10 years. Permanent jobs run around 50 per facility.
