PJM data center · https://askthegrid.com/assets/facilities/iron-mountain-data-center-va-3

Iron Mountain Data Center VA-3 is an operating data-center building at 11640 Hayden Road in Manassas, Virginia, within PJM. Prince William County's Build Out Analysis records the building as completed with 389,649 square feet of gross floor area. This profile distinguishes that county-reported building area from facility power or IT load and keeps building-specific facts separate from Iron Mountain's wider Manassas campus claims.

## Data quality

- The exact asset is consistently identified as Iron Mountain Data Center VA-3 at 11640 Hayden Road, Manassas; the county record reports it as completed in 2024 with a finaled building permit.
- No exact-asset local or trade-news article, community organization, petition, public-hearing record, opposition proceeding, or litigation record was identified. The exact-site evidence consists primarily of an official operator listing, a county building record, a design-firm project page, and a permit record.
- Campus-wide claims about jobs, incentives, renewable-energy matching, tenants, and other facilities were not attributed to VA-3. The reported VA-8/9 rezoning and related resident concerns were treated as a separate campus extension, not as evidence about VA-3.
- Removed uncited provider news result: Northern Virginia Data Centers | Manassas Data Centers | Iron Mountain
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
