State-level measures in Arizona
Every statewide moratorium, pause, siting restriction, or tax-incentive rollback in Arizona we can verify against a primary source. Strongest status first.
| Measure | Status | What it does | Source |
|---|---|---|---|
| HB 2649computer data centers; tax incentives | In force 2021-04 | Arizona HB 2649 (55th-1st-regular): computer data centers; tax incentives. Last action 2021-04-20: Signed by Governor. | |
| Arizona statewide (3-year pause on new data center tax exemptions, signed in FY budget)Arizona: On June 15, 2026 Gov. Katie Hobbs signed Arizona's ~$18B FY budget, which includes a three-year moratorium on NEW data center sales/use tax exemptions. | In force 2026-06 | On June 15, 2026 Gov. Katie Hobbs signed Arizona's ~$18B FY budget, which includes a three-year moratorium on NEW data center sales/use tax exemptions. Existing data centers keep their exemptions (5-10 year terms) and new facilities can still be built, they just cannot newly qualify for the incentive during the pause. The 2013-era incentive costs the state ~$38M/year; a mixed outcome curbing subsidies without restricting development. | |
| FY2027 budgetThree-year pause on data center sales-tax exemption | In force 2026-07 | Signed by Gov. Hobbs; imposes a three-year moratorium on new data center sales-tax exemptions (Jul 1 2026 to Jun 30 2029). Already-approved projects keep their exemptions. | |
| HB 4168Statewide moratorium on data centers through June 30, 2029 | In force 2026-07 | 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). The measure runs to June 30, 2029. | |
| HB 2756Rules for extra high load factor customers | Proposed 2026 | Would direct the Corporation Commission to adopt rules for extra high load factor customers, including review of contracts before execution and cost-of-service studies. Introduced; pending. | |
| Arizona (Senate disclosure bill)Arizona: On April 17, 2026, the Arizona Senate passed a bill that would require the state's major utilities to file reports every six months to the Arizona | Proposed 2026-04 | On April 17, 2026, the Arizona Senate passed a bill that would require the state's major utilities to file reports every six months to the Arizona Corporation Commission detailing new 'extra high load users' like data centers, including the number of new connections and connection requests. The bill now returns to the House for further action. This follows an ACC workshop on Large Load Users held April 16, 2026, where APS and SRP recommended new policies including a new extra high load factor (XHLF) rate, bring-your-own-power policies, and standard contracts requiring up-front financial support from data center customers. | |
| SB 1463Arizona SB 1463 (Sen. Priya Sundareshan, D - Senate Minority Leader) would repeal the state's transaction privilege and use tax exemption for qualifying large | Failed / vetoed 2026-01 | Arizona SB 1463 (Sen. Priya Sundareshan, D - Senate Minority Leader) would repeal the state's transaction privilege and use tax exemption for qualifying large data centers. Gov. Katie Hobbs called for the repeal in her January 2026 State of the State address, despite having voted for the original tax break as a state senator in 2013. Hobbs's plan also proposes a penny-a-gallon fee on data center water use. Rep. Neal Carter (R-San Tan Valley) sponsored a House companion to sunset the exemption. The Department of Revenue estimates the incentives cost the state ~$38M/year. A two-thirds supermajority is required to repeal a tax incentive, making passage difficult despite some bipartisan support. Gov. Hobbs called for repeal in her State of the State address and proposed a penny-per-gallon fee on data center water use ($6.5M/year for water conservation). The exemption costs $38.5M/year (up from $1.4M in 2020, projected to reach $60M+ by FY2027). SB 1463 (repeal data center tax exemption) failed to advance; the GOP legislature kept the breaks in its budget, which Gov. Hobbs vetoed in May partly over data center breaks. Repeal needed a 2/3 supermajority that never materialized. | |
| HB 2631Arizona: Governor Katie Hobbs called for repealing data center tax incentives which cost Arizona approximately $38.5 million per year. | Failed / vetoed 2026-02 | Governor Katie Hobbs called for repealing data center tax incentives which cost Arizona approximately $38.5 million per year. The bill would end the transaction privilege and use tax exemption for large data centers. Part of a broader national trend of states reconsidering data center tax breaks. The outcome remains pending. Gov. Hobbs called for repeal in her State of the State address and proposed a penny-per-gallon fee on data center water use ($6.5M/year for water conservation). The exemption costs $38.5M/year (up from $1.4M in 2020, projected to reach $60M+ by FY2027). HB 2631 (House companion tax-exemption repeal) failed like SB 1463; data center tax breaks were preserved in the GOP budget Hobbs vetoed. | |
| HB 2795Arizona: In Arizona, HB 2795 would prohibit counties (<500K pop) from denying zoning approval for small modular reactors after federal design certification | Failed / vetoed 2026-02 | In Arizona, HB 2795 would prohibit counties (<500K pop) from denying zoning approval for small modular reactors after federal design certification and site permitting. Allows SMR construction colocated with large industrial users (data centers) without ACC environmental compatibility certificate. Cleared House on party-line vote Feb 26, advancing to Senate. Gov. Hobbs vetoed similar bill in 2025. HB 2795 (industry-friendly SMR county-zoning preemption) failed Senate third reading 15-13-2 on April 8, 2026 and never reached the governor. |
City and county moratoria in Arizona
Most of the movement is local, where a building pause or permit halt does not need a legislative session. 6 tracked measures in Arizona, each with its source.
Where Arizona stands
Across the whole tracker we hold 334 state-level measures in 49 states and 1253 city and county measures, against 1419 primary sources. Arizona accounts for 9 of the state-level measures and 6 of the local ones.
By total measures on record it is #33 of the 50 states and DC carrying any tracked action, and #36 by city and county measures alone. Ranking is by count of sourced entries in this dataset, so it measures documented activity, not the size of the buildout.

What does bind large loads in Arizona
A moratorium is only one way a data center gets stopped. The grid operator decides whether it can connect at all, and on what terms. Arizona sits in 2 footprints.
APS/SRP/TEP vertically integrated (WECC); SPP's RTO West expansion (live 4/1/2026) added SPP RTO territory in Arizona per SPP.
States next door
5 of the 5 states bordering Arizona have at least one data-center measure on record. Restrictions tend to travel between neighbors, so this is usually where the next one comes from.

How to read this page
In force = a moratorium, siting restriction, or tax-incentive rollback that is currently enacted, by statute or executive order. Paused = a temporary hold on new incentives or applications. Proposed = introduced and still pending. Failed / vetoed = died in committee, was voted down, or was vetoed.
This page is generated from the same primary-sourced dataset as the national U.S. Data Center Moratorium Tracker and is re-checked on the same weekly cycle, whether or not anything changed. Legislative status changes quickly; it is informational, not legal advice. Spot something out of date in Arizona? Tell us.

Why Arizona is pushing back
The objections repeat from state to state: strain on the electric grid, water drawn for cooling, and the sense that a facility takes local resources without giving much back. SAVRN builds AI factories designed around those three objections: on-site power that does not lean on the public grid, direct-to-chip cooling that does not consume municipal water, and a training institute that puts local people to work inside the building.
