What's happening in Washington County
Facilities here with disclosed capacity draw 928 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.
Flexential Corp. has the largest presence in Washington 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 5 standardized 36 MW campuses in Washington County by 2035 — roughly 180 MW of new electricity demand and ~174 M gal/yr of cooling water. Under the higher-growth scenario (15%/yr) that climbs to 25 campuses (900 MW). For scale, we currently track 27 real data centers in Washington County (928 MW of reported power).
- Low growth5180 MW · ~174 M gal/yr cooling water
- Moderate growth5180 MW · ~174 M gal/yr cooling water
- High growth12432 MW · ~418 M gal/yr cooling water
- Higher growth25900 MW · ~870 M gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Washington 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.
