STACK Infrastructure Hillsboro: 148MW Pacific Northwest Hyperscale Campus

Status: Operational / Active Campus Expansion   |   Location: 4735 NE Starr Blvd & NE Brookwood Pkwy, Hillsboro, OR 97124, USA


Project Overview

STACK Infrastructure's Hillsboro Campus is a 148+ MW hyperscale data center development located in Hillsboro, Oregon, the heart of the Pacific Northwest's renowned Silicon Forest technology corridor. Spanning more than 60 acres across its POR01, POR02, and POR03 campuses, the development is purpose-built to support hyperscale cloud platforms, enterprise computing environments, and high-density artificial intelligence (AI) workloads. The campus offers scalable infrastructure with large data halls designed for high-performance computing while providing flexibility for future expansion. Power is delivered by Portland General Electric (PGE) and benefits from access to cost-effective zero-carbon renewable energy, including regional hydroelectric, wind, and solar resources, supporting customers with ambitious sustainability goals. The facility utilizes advanced waterside economization and the region's naturally cool climate to provide highly energy-efficient cooling with zero evaporation, reducing water consumption while maintaining optimal operating conditions. Strategically located on the Wave Business Hillsboro Data Center Ring, the campus provides low-latency connectivity to major domestic and international networks, including direct access to NCP and Jupiter transpacific subsea cable systems connecting North America with Asia Pacific markets. Combining renewable energy, sustainable cooling technologies, scalable hyperscale infrastructure, and world-class network connectivity, STACK Infrastructure's Hillsboro Campus is a leading destination for cloud providers, AI deployments, and enterprise digital infrastructure in the Pacific Northwest.
