Data centers in Essex County, NJ

Everything on file with the regulator, added up. Every figure links to the filing it came from.

1data center site

1 permitted facilities.

These facilities hold active air permits in EPA's national registry. Groundwork has not yet read NJ's permit documents, so generator counts and permitted emissions show as pending here — unlike Virginia, where every figure is read from the permit itself.

What this does — and doesn't — mean.

It is smaller than it sounds

These are emergency backup generators. They are permitted to run during grid outages and for routine testing — typically tens of hours a year, not continuously. A permit is a ceiling on what a site may emit, not a measurement of what it does emit.

A permit also is not a building. An issued permit establishes approval; it does not establish that anything is built, energised or running.

None of the 1 sites here that Groundwork could locate sits in a FEMA Special Flood Hazard Area.

It is bigger than any one filing shows

No single permit discloses the total permitted in this county. That number exists only because 1 separately-published filings were added together. Each one, read alone, looks routine.

What NJ publishes

Groundwork has this state’s facilities from EPA’s national air-permit registry, but has not yet read the state’s own permit documents. Generator counts and permitted emissions therefore show as pending.
