Aligned Data Centers PHX3 Phoenix: 150MW Hyperscale & AI Campus
Status: Active Construction Phase | Location: Greater Phoenix Metropolitan Area (Union Hills / West Valley Corridor), Maricopa County, AZ, United States
Project Overview
Aligned Data Centers’ PHX-03 is a landmark 150 MW hyperscale data center campus strategically located within the rapidly expanding West Valley/Phoenix data center corridor, one of North America’s fastest-growing digital infrastructure markets. Building upon Aligned’s established presence in Maricopa County alongside its operational PHX-01 and PHX-02 facilities, PHX-03 is purpose-built to support hyperscale cloud providers, enterprise customers, and the rapidly increasing demands of artificial intelligence (AI), machine learning, and high-performance computing (HPC) workloads. Designed for large-scale cloud infrastructure and next-generation generative AI deployments, the campus incorporates Aligned’s patented Delta Cube (Delta³) cooling technology together with advanced direct liquid cooling (DLC) infrastructure, enabling exceptional thermal efficiency while significantly reducing water consumption in Arizona’s arid desert climate. This innovative cooling approach supports ultra-high-density GPU clusters and future AI hardware while improving operational sustainability and energy performance. The facility is powered by resilient high-voltage electrical infrastructure supplied by Arizona Public Service (APS) and Salt River Project (SRP), ensuring scalable and reliable energy delivery for mission-critical computing environments. As a carrier-neutral campus, PHX-03 offers access to major national dark-fibre routes, enabling low-latency connectivity, diverse network paths, and seamless interconnection with leading telecommunications providers and cloud platforms through direct cloud on-ramps. Combined with enterprise-grade security, resilient power architecture, scalable infrastructure, and sustainability-focused engineering, Aligned Data Centers’ PHX-03 provides a future-ready digital platform for organisations deploying hyperscale cloud services, AI training clusters, and next-generation data-intensive applications in one of the United States’ premier data center markets.
