What's happening in Fairfax County
Facilities here with disclosed capacity draw 5 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.
Amazon.com, Inc. has the largest presence in Fairfax 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 Fairfax 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 19 campuses (684 MW). For scale, we currently track 27 real data centers in Fairfax County (5 MW of reported power).
- Low growth5180 MW · ~174 M gal/yr cooling water
- Moderate growth5180 MW · ~174 M gal/yr cooling water
- High growth8288 MW · ~279 M gal/yr cooling water
- Higher growth19684 MW · ~661 M gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Fairfax 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.
