What's happening in Chelan County
Facilities here with disclosed capacity draw 840 MW from the local grid. Data-center load on this scale is the single biggest driver of recent capacity-market price increases — costs that flow through to every ratepayer in the service territory, not just the operators.
Alphabet Inc. has the largest presence in Chelan County. We resolve project codenames and shell LLCs back to the corporate parent wherever the public record allows, so the table below names who is actually behind each site.
Below: every tracked facility in the county, the active state legislation that names it or its county, and local news. Commissioner vote records arrive in a later release; the placeholders show where that accountability data will land.
2035 Buildout Outlook
Under the model's moderate-growth scenario (5%/yr annual load growth), PNNL's IM3 model sites about 2 standardized 36 MW campuses in Chelan County by 2035 — roughly 72 MW of new electricity demand and ~70 M gal/yr of cooling water. For scale, we currently track 5 real data centers in Chelan County (840 MW of reported power).
- High growth272 MW · ~70 M gal/yr cooling water
- Higher growth272 MW · ~70 M gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Chelan County (the rest to mechanical/air cooling), a split it derives from local water stress and wet-bulb temperature.
These are modeled candidate sites, not announced or permitted facilities. PNNL's IM3 model places identical 36 MW unit-campuses at feasible locations under each scenario — it shows where demand could concentrate, never a specific parcel. Figures use a market-gravity weight of 50. How the model works.
