Ranked 5 of 14 counties.

Fauquier County holds 521 permitted backup generators across 4 sites. The median tracked county with any generator data has 248.

Counties with permitted generator counts Groundwork has read from permit documents. Only Virginia publishes permits in a form that makes this countable today, so this ranking is Virginia-only — not a claim that no county elsewhere is denser.

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 4 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 521 generators permitted in this county. That number exists only because 4 separately-published filings were added together. Each one, read alone, looks routine.

What VA publishes

Virginia is the only state that publishes a data-center-specific air permit list, with the issuance document for every permit. That is why Virginia pages carry permit counts, generator counts and permitted NOx, and most other states do not.
