Arizona
DataCentersExposed tracks 86 AI data centers in Arizona — 17 operating and 17 in the pipeline — across 5 counties, drawing 11.3 GW of reported power demand from 18 tracked corporate operators. Arizona's data-center tax break cost the state $38.5M in forgone revenue in FY2025.

Arizona at a glance
The largest footprint in Arizona belongs to CyrusOne LLC, behind 8 tracked facilities. Prime Data Centers, Microsoft Corporation, and QTS Realty Trust, LLC round out the most active operators in the state. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.
Geographically, the buildout clusters: Maricopa County leads Arizona with 75 facilities and a composite risk score of 63/100. Pinal County and Pima County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.
Arizona is not done growing. 17 facilities are in the pipeline — proposed, permitted, or under construction — which is where residents still have a say at zoning hearings and in rate cases. Each pending project is a decision about land, water, electricity prices, and tax revenue that hasn't been finalized.
We also surface the accountability trail: 8 state bills mentioning data centers and 6 recent news items are tracked for Arizona below, pulled from LegiScan and GDELT and refreshed automatically. Legislation is linked to the counties and operators it names; news is classified by community sentiment.
2035 Buildout Outlook
Under the model's moderate-growth scenario (5%/yr annual load growth), PNNL's IM3 model sites about 14 standardized 36 MW campuses in Arizona by 2035 — roughly 504 MW of new electricity demand and ~322 M gal/yr of cooling water. Under the higher-growth scenario (15%/yr) that climbs to 77 campuses (2.8 GW). For scale, we currently track 86 real data centers in Arizona (11.3 GW of reported power).
- Low growth9324 MW · ~200 M gal/yr cooling water
- Moderate growth14504 MW · ~322 M gal/yr cooling water
- High growth381.4 GW · ~583 M gal/yr cooling water
- Higher growth772.8 GW · ~749 M gal/yr cooling water
The model assigns ~66% of these campuses' cooling to evaporative water cooling in Arizona (the rest to mechanical/air cooling), a split it derives from local water stress and wet-bulb temperature.
These are modeled candidate sites, not announced or permitted facilities. PNNL's IM3 model places identical 36 MW unit-campuses at feasible locations under each scenario — it shows where demand could concentrate, never a specific parcel. Figures use a market-gravity weight of 50. How the model works.

The taxpayer price tag
“In FY 2025, businesses deducted an estimated $770.5 million for this purpose. Had the transactions been taxable at a 5% rate, they would have generated about $38.5 million in tax. [Summary table, Deduction Code 565: 38,527,463]”
Program-wide cost of Arizona's data-center tax incentive(s), reported by the state — not attributable to a single facility. “Proj” = the state's own forward estimate; all other figures are realized/audited. Each links to its primary source.
