Data Center Market Overview in Washington State

Washington's data center market is divided into several distinct geographic clusters.

Central Washington is the state's largest hyperscale development area, with Quincy serving as a major hub for largest data center developers like Microsoft, Sabey Data Centers, Vantage Data Centers, CyrusOne, H5 Data Centers, and NTT. The region benefits from access to Columbia River hydropower and large-scale industrial sites.

East Wenatchee and Malaga have emerged as additional hyperscale locations, driven primarily by Microsoft's continued expansion. These projects are supported by regional public utility districts and new power, cooling, and water infrastructure.

Seattle and the Puget Sound region operate differently from Central Washington. The Seattle market is more focused on colocation, network connectivity, enterprise infrastructure, and carrier-dense facilities. Operators include Equinix, Digital Realty, Sabey, H5 Data Centers, DataBank, Digital Fortress, and others.

Eastern Washington is becoming an increasingly important location for new large-scale developments. AWS is planning its multibillion-dollar Wallula Gap campus, while Trammell Crow Company is evaluating a large data center development in West Richland.

Data Centers in Washington State: Major Locations

Quincy

Quincy is one of Washington's largest and most established hyperscale data center markets. Its growth has been supported by access to low-cost Columbia River hydropower, high-capacity utility infrastructure, industrial land, fiber connectivity, and a climate suitable for large-scale data center operations. Major operators in Quincy include Microsoft, Sabey Data Centers, Vantage Data Centers, CyrusOne, H5 Data Centers, and NTT.

East Wenatchee

East Wenatchee is a growing Microsoft data center location in Douglas County. Microsoft's EAT06 and EAT09 facilities are part of the company's expanding regional infrastructure supporting cloud and AI workloads.

Malaga

Malaga, located in Chelan County near Wenatchee, is another major Microsoft development area. Microsoft's Malaga campus includes EAT13 and has the potential to support multiple large data center buildings.

Seattle and Puget Sound

Seattle remains Washington's primary colocation and connectivity market. The region has a large concentration of network providers, enterprise infrastructure, cloud connectivity services, and carrier hotels.

The market is structurally different from Quincy and Central Washington because Seattle developments are generally more focused on colocation and network-intensive infrastructure rather than large greenfield hyperscale campuses.

Tri-Cities and West Richland

The Tri-Cities region is emerging as a potential new location for large data center developments. Projects in West Richland and Richland are being evaluated against growing concerns about electricity demand, transmission capacity, and regional infrastructure.

Wallula Gap and Walla Walla County

Wallula Gap Business Park in Walla Walla County is the proposed location of AWS's major multibillion-dollar data center campus. The project represents one of the largest upcoming data center developments in Washington.

AI Data Centers in Washington State

Washington is increasingly attracting infrastructure intended to support artificial intelligence and high-density cloud computing workloads.

Microsoft, AWS, and other hyperscale operators are expanding infrastructure capable of supporting AI workloads, but many individual facilities have not publicly disclosed whether they will be dedicated exclusively to AI training, AI inference, cloud computing, or a combination of workloads.

The strongest AI-related development trends in Washington include:

• AWS's large-scale Wallula Gap campus

• Microsoft's East Wenatchee and Malaga expansions

• Proposed large-load data center developments in West Richland and the Tri-Cities

• Growing demand for high-density computing infrastructure

• New investments in nuclear, renewable, and grid infrastructure

Washington's AI data center pipeline is therefore best described as a rapidly growing hyperscale and high-density computing market rather than a collection of publicly confirmed AI-only facilities.

Seattle Data Center and Colocation Market

Seattle is Washington's primary colocation and connectivity market. Unlike Quincy and Central Washington, where hyperscale campuses dominate, Seattle's data center ecosystem is driven by enterprise customers, network connectivity, cloud on-ramps, financial services, telecommunications, and colocation demand.

Major operators in the Seattle and Puget Sound market include:

• Equinix

• Digital Realty

• Sabey Data Centers

• H5 Data Centers

• DataBank

• Digital Fortress

• Lumen

• Centeris

Seattle is also an important network hub because of its connection to international subsea cable systems and Pacific Northwest fiber infrastructure.

Seattle Data Center Moratorium

Seattle has also introduced stricter controls on large new data center developments.

In June 2026, the Seattle City Council approved a one-year moratorium affecting certain new large data centers with electricity demand above 20 MVA.

The moratorium can potentially be extended and reflects growing concerns about electricity demand, grid infrastructure, and the impact of large data center loads on the city's power system. The policy development highlights the increasing importance of power availability in determining where future data centers can be developed in Washington.

Data Center Power and Infrastructure in Washington

Access to low-carbon electricity has historically been a major advantage for data center development in Washington. Hydroelectric power from the Columbia River has supported major hyperscale growth in Quincy and the Wenatchee Valley, with key utilities including Grant County PUD, Chelan County PUD, and Douglas County PUD.

However, rapid growth in large-load projects is increasing pressure on power infrastructure. Grant County PUD's large-load queue has reached nearly 2,900 MW of requested peak demand, with data centers accounting for a significant share. New projects may require additional transmission, substations, generation agreements, infrastructure contributions, and longer interconnection timelines.

Washington is also exploring new power sources. Energy Northwest's proposed Cascade Advanced Energy Facility could provide future small modular reactor capacity, with AWS associated with an agreement for up to 320 MW in its initial phase and potential expansion to approximately 960 MW. Helion Energy has also proposed a fusion power project in Malaga linked to a minimum 50 MW power purchase commitment for Microsoft.

Water and cooling infrastructure are another growing consideration. Microsoft's Malaga development requires dedicated cooling water infrastructure, while AWS's Wallula Gap campus is designed primarily around air cooling. As AI workloads increase data center power density, electricity availability, cooling systems, and water infrastructure will become increasingly important factors in Washington's future data center development.

Conclusion

Washington remains an important market for data center projects, supported by hydropower, strong connectivity, available land, and an established technology ecosystem. With more than 50 tracked projects and approximately USD 12.9 billion in pipeline investment, the state's data center development outlook remains strong.

Major projects such as the AWS Wallula Gap Data Center Campus, West Richland Data Center Campus, and Microsoft's EAT06, EAT13, and EAT09 demonstrate the scale of investment expected across the state. However, securing reliable power, transmission capacity, and supporting infrastructure will increasingly determine how quickly these upcoming data centers in Washington State move from planning to construction.
