What's happening in Essex County
TierPoint, LLC has the largest presence in Essex 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 1 standardized 36 MW campus in Essex County by 2035 — roughly 36 MW of new electricity demand and ~35 M gal/yr of cooling water. For scale, we currently track 2 real data centers in Essex County.
- Higher growth136 MW · ~35 M gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Essex 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.
