STACK Infrastructure announced plans for a 144MW data center campus in Loudoun County, Virginia, further strengthening its presence in the world’s largest data center market. The new development, located within the Ashburn data center cluster, will consist of two 72MW, two-story buildings designed to support AI, machine learning (ML), and cloud workloads. The facility will feature advanced closed-loop water cooling systems for high-density computing environments and will be powered by 100% renewable energy. An on-site substation will provide direct power access to ensure high reliability.
The campus aligns with Loudoun County’s long-term development plans, integrating a compact, high-efficiency design more commonly found in dense urban environments. This expansion adds to STACK’s growing data center platform, which now includes 4.0+GW of active and under-development capacity globally, with 6.0+GW of planned and potential expansions. The project underscores STACK’s commitment to scalable, sustainable, and client-driven infrastructure solutions in key digital markets.
