Washington Data Centers: Complete Directory & Market Overview

Browse all 11 data center facilities in Washington — across 2 counties — on the Washington data centers directory.

Washington State: Pacific Northwest's Data Center Corridor

Washington's King County has become one of the most important data center markets in the western US, anchored by Seattle's technology ecosystem and abundant hydroelectric power from the Columbia River basin. Central Washington (Quincy, Ephrata) is emerging as a secondary hyperscale market as operators seek lower-cost power further from urban centers. The state's proximity to Asia-Pacific submarine cable landings makes it critical for trans-Pacific data routing. TierPoint, Digital Realty, Equinix, and Cologix operate the core colocation fabric in Seattle.

About the Washington Data Center Market

Data centers in Washington serve a range of industries including financial services, healthcare, government, and enterprise IT. The national data center market is undergoing a $600+ billion investment cycle driven by AI workload demand — with the US AI data center market projected to grow from $5.2 billion in 2025 to $57 billion by 2035 at a 27% compound annual growth rate.

Power infrastructure has emerged as the primary constraint on new builds across the US, with approximately 50% of planned projects facing delays due to grid limitations. The 2026 market is pivoting from large AI training clusters to inference infrastructure — smaller, faster, and closer to end users — which is driving distributed expansion across secondary markets nationwide.
