Washington

The largest footprint in Washington belongs to Sabey Data Centers, behind 12 tracked facilities. Microsoft Corporation, Centeris, and Vantage Data Centers Holdings, LLC round out the most active operators in the state. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.

Geographically, the buildout clusters: Grant County leads Washington with 12 facilities and a composite risk score of 39/100. Chelan County and King County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.

Washington is not done growing. 2 facilities are in the pipeline — proposed, permitted, or under construction — which is where residents still have a say at zoning hearings and in rate cases. Each pending project is a decision about land, water, electricity prices, and tax revenue that hasn't been finalized.
