Microsoft — Quincy, Washington AI Data Center Campus

Microsoft’s Quincy, Washington campus is one of the company’s oldest and largest data center investments in the United States. Located in Grant County in eastern Washington State, the campus has been operational since 2007 and has grown into one of Microsoft’s most significant compute concentrations globally.

Quincy was selected for its access to exceptionally cheap, abundant hydroelectric power from the Columbia River basin — electricity rates from the Grant County Public Utility District are among the lowest in the nation, historically under 3 cents per kWh. The Pacific Northwest’s renewable hydropower grid gives the Quincy campus one of the lowest carbon intensities of any Microsoft Azure deployment. The facility supports Azure’s West US regions and plays a central role in Azure AI services including OpenAI API deployments, Microsoft Copilot, and Azure Machine Learning training.

The campus spans thousands of acres and includes some of Microsoft’s largest data center buildings by floor area. Grant County’s economy has been substantially shaped by Microsoft’s presence, which has spurred development of the broader local data center cluster — including facilities from Intuit, Dell, and Sabey Data Centers. Microsoft has made multi-billion-dollar investments in Quincy over its history and continues to expand capacity there as AI workload demand grows.
