Phoenix, Arizona has become one of the fastest-growing datacenter markets in the United States — driven by cheap land, favorable power costs relative to California and Virginia, and a state government actively courting technology investment. What was a secondary market five years ago is now regularly mentioned alongside Ashburn, Dallas, and Chicago as a top-tier destination. The Phoenix metro now hosts over 40 tracked facilities, with 8 major projects in active construction simultaneously as of Q1 2026.
For vendors, this matters for one reason: construction activity at this scale creates procurement opportunities that simply don't exist in mature markets. New builds need everything — UPS systems, battery strings, generators, cooling, cabling, fire suppression, access control. The question is who gets the contracts.
The 8 Projects You Need to Know
1. CyrusOne Chandler Campus — Phase 3 (Started Q2 2025)
CyrusOne's existing campus in Chandler (Wild Horse Pass area) is one of the largest in the Southwest. A 2025 Maricopa County permit filing — #2025-BLD-048821 — indicates a 120MW expansion phase currently in structural construction. The project involves a new 6-story building with a full cooling plant. Equipment installation is expected to begin Q3 2026. CyrusOne's Phoenix campus page lists current available capacity.
2. Digital Realty PHX7/PHX8 (Permitted December 2025)
Digital Realty, already operating two facilities in the Phoenix metro, filed permits in December 2025 for two additional buildings at its existing Phoenix campus site. Combined capacity: approximately 90MW. The timing aligns with a hyperscaler pre-lease that Digital Realty publicly referenced in its Q4 2025 earnings call.
3. Google Maricopa County Expansion (Ground Broken Q1 2026)
Google's existing campus in Maricopa (south of Phoenix) is expanding. An Arizona Corporation Commission utility filing from January 2026 requests an additional 180MW of interconnection capacity — the clearest possible signal of a major construction phase. Ground was broken in Q1 2026. Google's Maricopa facility page documents the existing campus footprint.
4. Meta Goodyear — West Valley Hyperscale (Approved Late 2025, Permits Filed February 2026)
Meta received Goodyear City Council approval in late 2025 for a new 500-acre hyperscale campus. Phase 1 permits were filed in February 2026 for two 50MW buildings. The full buildout is expected to reach 400MW+ over 5 years. This is the single largest new datacenter project in Arizona history by announced scale.
5. Aligned Data Centers — Deer Valley (Ground Broken Q4 2025)
Aligned, known for its adaptive cooling technology, broke ground on a new 80MW campus in the Deer Valley area of Phoenix in Q4 2025. The project was fast-tracked through permitting in under 90 days, and Aligned has publicly stated they have pre-committed tenants for the first two buildings.
6. Iron Mountain — Mesa (Active Construction)
Iron Mountain acquired a 50-acre parcel in Mesa in 2025 and has since filed structural permits for a 40MW initial phase. Construction is actively underway. Iron Mountain's operations team has been posting facility-specific roles on Indeed since January 2026 — a reliable signal that commissioning is approaching.
7. Switch SUPERNAP West Valley Expansion
Switch's existing campus in Grand Prairie (near I-20) is undergoing its largest expansion since opening. Internal sources indicate the expansion adds 60MW across two new data halls. Permit filings confirm mechanical and electrical work is actively permitted.
8. QTS Phoenix — New Campus (Early Permitting)
QTS Realty (owned by Blackstone) announced a new Phoenix-area campus in late 2025. The project is in early permitting, with 200MW of planned capacity. For vendors, this is the earliest-stage opportunity — the procurement cycle hasn't started yet, which means there's time to get on the approved vendor list before bidding opens.
What the Phoenix Market Means for Vendors
The concentration of construction activity in Greater Phoenix right now is unusual — most markets have 1–2 active major projects at any time. Phoenix currently has 8+. That creates a vendor dilemma: you can't be everywhere at once, and each project has different procurement windows.
The strategic play is to focus on projects that are 6–12 months from equipment installation — not the ones breaking ground today (too early) and not the ones commissioning next month (too late). Right now, the CyrusOne, Digital Realty, and Google projects hit that window. The Meta and QTS projects are the pipeline opportunities.
Kova Stack tracks permit status, utility interconnection filings, and job posting patterns for every Phoenix project. When a project transitions from structural construction to MEP fit-out, we flag it — because that's when UPS vendors, cooling contractors, and cabling companies need to be calling.
