Iron Mountain's January 20, 2025 location overview reports VA-2 at 24 MW total potential capacity. Retained separately from the later 36 MW figure; it is not treated as an interconnection request, contracted capacity, critical IT load, or campus aggregate.

Utility: NOVEC (Northern Virginia Electric Cooperative)
Balancing authority: PJM Interconnection, LLC
ISO / RTO: PJM Interconnection (PJM-RTO)
Redundancy: Tier III designed/concurrently maintainable facility with block N+1 configuration; A/B underground utility feeds; high-efficiency N+1 block-redundant cooling; and block-redundant N+1 generators and UPSs.
Backup generation: Emergency diesel engine-generator sets are permitted at Iron Mountain's source, which explicitly includes VA-2 at 11660 Hayden Road. The VA-2 location overview describes block-redundant N+1 generators. The public permit does not allocate a generator count or MW rating specifically to VA-2.
Power sources: NOVEC-supplied grid electricity · 100% matched renewable power, as reported by Iron Mountain; the physical renewable source is not specified · Diesel fuel for emergency backup generation
Grid flexibility: No facility-specific demand-response, load-shifting, or other flexible-load enrollment is identified. The DEQ permit allows emergency diesel generators to operate during an ISO-declared emergency, but that does not establish a VA-2 demand-response program.

Construction: VA-2 is an operating, purpose-built two-story data-center facility. Prince William County's building record identifies one VA2 building as completed in 2019 under permit BLD2018-04430, with the permit finaled on 2019-10-23 and gross floor area of 325,918 square feet. Iron Mountain separately publishes 221,500 gross square feet (another page states 221,578 square feet) and 36 MW of capacity. A December 2019 report stated that construction had begun and targeted first-phase completion in Q1 2020; this target is distinct from the county's completion record and is not treated as an explicit commercial-operation date. The operator currently lists VA-2 as operational.
Land transaction: In 2016, Iron Mountain announced its intention to establish the Manassas data-center campus on 83 acres at 11650 Hayden Road; the related county/Industrial Development Authority agreement included $500,000 in water and sewer availability fee credits. The cited record does not establish a VA-2-specific purchase price or closing date. The later 40-acre adjacent-site acquisition for two additional buildings is excluded from the VA-2 facility record.
