Strategic development reinforces STACK's commitment to scalable, sustainable, and client-driven digital infrastructure
STACK Infrastructure Expands Loudoun County Footprint with 144MW Hyperscale Campus
Positioned in the greater Ashburn data center cluster, this campus will provide scalable capacity across two 72MW, two-story buildings. Designed with advanced cooling capabilities, the facility supports multiple deployment models for AI, ML, and cloud workloads, including closed-loop water cooling systems that maximize efficiency for high-density environments. The campus will utilize 100% renewable energy and draw power from an on-site substation, ensuring reliability.
"STACK is committed to delivering critical capacity where our clients need it most, and Loudoun County remains a critical hub for digital infrastructure,” said Ty Miller, Chief Commercial Officer, STACK Americas. "STACK's continued investment in Northern Virginia reinforces our long-term commitment to delivering best-in-class digital infrastructure in the world's most vital data center market."
The location of the campus aligns with Loudon County's long-term development plans, which, in part, designate this area for data center use due to its proximity to the airport. Given the characteristics of this site, STACK is implementing a data center design that is more commonly found in dense urban environments. This approach prioritizes thoughtful integration with the surrounding area, reinforcing STACK's commitment to community stewardship and responsible development.
This strategic expansion further strengthens STACK's Northern Virginia portfolio and adds to its growing global platform, which includes 4.0+GW of active and under development capacity and an additional 6.0+GW of planned and potential expansion worldwide. Featured developments include:
- A 500MW south Dallas campus, spanning 100 acres, strategically engineered to accommodate both shell and turnkey deployments.
- A 56MW Toronto campus, spanning 19 acres, includes an existing 8MW data center and 48MW expansion capacity, all supported by committed power.
