QTS Phoenix 3: What Glendale’s Permit Record Establishes

A West Valley campus with a public-market connection

QTS Phoenix 3 is a data-center development in Glendale, Arizona, with a documented connection to Blackstone-managed capital. QTS identifies the campus on its current operator website and lists individual buildings along West Camelback Road. For readers following the West Valley’s infrastructure expansion, this establishes a specific site to track without assuming that its entire master plan has reached operation.

The public-market connection is Blackstone, ticker BX. Affiliated funds completed their QTS acquisition in August 2021, and QTS ceased public listing. Our Blackstone company profile explains that ownership route. Buying an asset-manager stock is different from holding direct equity in this particular campus; the sources do not quantify a PHX3 earnings contribution to BX.

What the large capacity figure actually means

May 2024 reporting by Data Center Dynamics described a proposed 750 MW critical-capacity campus with 16 buildings, approximately 3 million square feet and a planned substation. Those are historical development figures. They should not be presented as the amount of computing capacity currently operating, occupied by tenants or earning rent.

The distinction is central to AI infrastructure analysis. A master plan establishes ambition and potential scale; productive deployment requires construction completion, electrical service, equipment readiness and customer acceptance. Data center power demand can also arrive in phases, so each phase needs its own dated evidence.

Glendale identity, Litchfield Park mailing addresses

The current QTS page calls the campus Glendale while listing Litchfield Park postal addresses for its buildings. Postal labels alone should not be used to assign city jurisdiction. Our project entry follows the operator’s campus identity and marks its map location as an approximate campus area, rather than claiming a surveyed parcel or verified entrance.

PHX3 also needs to remain separate from QTS’s other Phoenix-area facilities. A regional portfolio can contain operating assets and developing assets at the same time. Combining their capacities or status would obscure what is actually known about the Glendale project.

What the Glendale permit establishes—and what it does not

The City of Glendale's January 2025 combined permit report lists permit 176978, issued January 7, 2025, to QTS Glendale I LLC at 17316 W Camelback Road. QTS lists that same address as Phoenix 3 DC13. The address match provides primary-source evidence of permitted activity at one PHX3 building address.

The city classifies the permit as industrial and reports a declared valuation of $36,416,354. That number is not verified project spending or final construction cost. The permit record does not establish inspection completion, occupancy, utility energization, delivered megawatts or customer acceptance. A separate Goodyear-hosted plat remains adjacent-land context only.

No assumed tenants or supplier winners

QTS is the named private operator; Blackstone-affiliated funds supply the verified platform ownership connection. The sources reviewed do not establish a named PHX3 tenant, GPU vendor, utility service agreement or construction-company award. Wider Phoenix-market activity by major technology firms is not evidence that those companies participate here.

This matters when connecting infrastructure coverage to public stocks. A company can benefit from regional demand without holding a specific campus contract. Our internal links therefore lead to the supported Blackstone relationship, while customer and supplier exposure remain unresolved rather than being inferred from an AI theme.

Investor takeaway: follow delivery, not just the plan

Our analysis: PHX3 is a concrete AI infrastructure investment case study within the QTS platform. Permit evidence advances the record beyond a land-only proposal, but the next meaningful evidence is delivery: final inspection, energization, occupancy and customer acceptance. An announced megawatt total cannot substitute for that sequence.

Financing terms, realized construction spending, lease economics and campus-level earnings are also unresolved. The opportunity to track a substantial campus is real; the economic assessment depends on evidence that turns planned capacity into productive use. Our project profile provides the dated source trail, remaining questions and next catalysts without publishing a revenue forecast.
