Stack Infrastructure Stafford Technology Campus (STC Campus)
Status: Planned / Pre-construction Phase (Announced January 2025) | Location: 500-acre tract adjoined by landfill/light industrial zones, Stafford County, Virginia, USA
Project Overview
A monumental 500-acre technology development represents STACK Infrastructure's largest flagship data center campus to date, setting a new benchmark for hyperscale digital infrastructure in Northern Virginia, one of the world's most important data center markets. Designed as a next-generation AI and cloud computing hub, the master-planned campus spans four interconnected sub-campuses and is expected to accommodate up to 19 individual data centers, providing exceptional scalability for global hyperscalers, cloud service providers, and enterprise customers. Engineered to deliver massive power capacity and future-ready infrastructure, the campus is built to support high-density GPU deployments, artificial intelligence training clusters, large language models (LLMs), high-performance computing (HPC), and next-generation cloud workloads. Advanced power distribution, resilient utility connectivity, and ultra-low-latency fiber networks will enable the campus to meet the rapidly growing compute demands driven by AI adoption worldwide. A key differentiator of the development is its strong sustainability strategy, including innovative closed-loop water systems and environmentally responsible cooling technologies that significantly reduce freshwater consumption while minimizing environmental impact. By combining large-scale capacity, operational resilience, and sustainable infrastructure, the project reinforces Northern Virginia's position as the global epicenter of digital infrastructure and supports the continued expansion of AI-driven cloud ecosystems. The landmark development also reflects STACK Infrastructure's long-term commitment to delivering hyperscale campuses capable of supporting the next generation of intelligent applications, digital services, and enterprise transformation.
