Data centers in Philadelphia County, PA
Everything on file with the regulator, added up. Every figure links to the filing it came from.
4 permitted facilities.
These facilities hold active air permits in EPA's national registry. Groundwork has not yet read PA'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.
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.
No single permit discloses the total permitted in this county. That number exists only because 4 separately-published filings were added together. Each one, read alone, looks routine.

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.
