What's happening in Grant County
Facilities here with disclosed capacity draw 1.5 GW 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.
Microsoft Corporation has the largest presence in Grant 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 11 standardized 36 MW campuses in Grant County by 2035 — roughly 396 MW of new electricity demand and ~35 M gal/yr of cooling water. Under the higher-growth scenario (15%/yr) that climbs to 60 campuses (2.2 GW). For scale, we currently track 12 real data centers in Grant County (1.5 GW of reported power).
- Low growth8288 MW · ~35 M gal/yr cooling water
- Moderate growth11396 MW · ~35 M gal/yr cooling water
- High growth291.0 GW · ~104 M gal/yr cooling water
- Higher growth602.2 GW · ~209 M gal/yr cooling water
The model assigns ~9% of these campuses' cooling to evaporative water cooling in Grant 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.
