Overview

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

via PNNL IM3 (CC BY 4.0)

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).

Modeled new campuses by demand-growth scenario
  • High growth2
    72 MW · ~70 M gal/yr cooling water
  • Higher growth2
    72 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.

County commissioners

How the Chelan County board votes on each data-center matter — the rezonings, the abatements, the water permits — is built from public-meeting minutes and roll-call records. Know of a vote we should be tracking? Tell us.

Methodology & sources

The risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%). Water and land are not yet measured for our facilities, so those arcs render as "not yet measured" and the weights are renormalized over the factors we can source today — when the data lands, the score updates.

Every row carries a confidence level (high / medium / low) and a source URL. Spot an error? Tell us.
