Arizona
Arizona’s data center politics are driven less by elections than by active state and local fights over water, grid costs, and siting, with Hobbs, the ACC, and several municipalities tightening scrutiny.
IARM Domain Signals
Water/Geology is the most stressed domain: Tucson/Project Blue and Hobbs’ agenda both center on water use, Colorado River stress, and the politics of who absorbs the costs of large consumptive loads (KJZZ, KJZZ). Energy/Power is the second major stressor because the ACC and legislature are focused on protecting retail customers from transmission and interconnection cost shifts for very large loads (Arizona Corporation Commission, Arizona Legislature).
IIKey 2026 Races
None identified as a race in which data centers are a dominant, defining campaign issue. The closest political storyline is Gov. Katie Hobbs (D), who has made data-center water fees and repeal of the tax exemption part of her 2026 agenda, while former U.S. Sen. Kyrsten Sinema (ind.) has lobbied locally for specific projects rather than running in 2026 (KJZZ, KJZZ).
IIIMoratorium · Ban Status
No statewide data-center moratorium or ban was enacted in Arizona as of May 2026, and the session’s statewide pause-style bills did not advance into law; MultiState reported that Arizona’s moratorium-style proposals stalled while local governments were moving ahead with targeted restrictions (MultiState, MultiState). Tucson advanced a city code amendment to regulate data centers, and city staff said a moratorium would have to be legally defensible and likely limited to 120 days (KJZZ). Chandler already rejected a proposed AI data center in December 2025, and Marana opponents pursued a referendum against rezoning tied to Project Blue (KJZZ, Axios).
IVRatepayer · Cost-Shift Legislation
HB 2756 is the clearest Arizona ratepayer-protection measure: it would require the Arizona Corporation Commission to adopt rules so new grid-connection costs for data centers are not shifted to other retail customers, and it would require cost-of-service studies that could support a new customer class or rate design for extra-high-load customers (Arizona Legislature, Arizona Corporation Commission). The ACC separately opened docket E-00000A-25-0069 and held an April 2026 workshop emphasizing that large loads should pay the costs they cause and that Arizona should protect residential and small-business customers from cost shifts (Arizona Corporation Commission, Arizona Corporation Commission).
VBallot Measures
None identified. A Marana referendum effort was underway in February 2026 over rezoning tied to a data-center proposal, but no Arizona statewide or local November 2026 ballot measure was confirmed in the sources gathered (Axios, Ballotpedia).
VITop Contested Sites
1) Project Blue, southeast of Tucson / Pima County, by Beale Infrastructure (with Humphrey’s Peak Power mentioned in reporting): highly contested, with Tucson rejecting annexation and a water dispute escalating into legal and political fights; by May 2026 the project was still advancing but under heavy opposition and water constraints (Axios, KJZZ). 2) Project Baccara, near Glendale/Surprise and Luke Air Force Base, by Michigan-based developer Takanock: Maricopa County approved a military-compatibility permit despite local pollution, noise, water, and air-base safety concerns (KJZZ). 3) Chandler Price Road AI data center proposal by New York-based Active Infrastructure: rejected unanimously in December 2025 after intense community pushback, but it remains a landmark cancellation in Arizona politics (KJZZ).

“We are a top two market in the world for data centers, and so I don't know that we need to be subsidizing them, that Arizona taxpayers need to be subsidizing them,” Gov. Katie Hobbs said, as reported by KJZZ on Jan. 9, 2026 (KJZZ).
