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 Sussex County by 2035 — roughly 72 MW of new electricity demand and ~70 M gal/yr of cooling water. Under the higher-growth scenario (15%/yr) that climbs to 4 campuses (144 MW). For scale, we currently track 1 real data center in Sussex County.
- High growth272 MW · ~70 M gal/yr cooling water
- Higher growth4144 MW · ~139 M gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Sussex 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 Sussex 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.
