# Amazon AWS IAD-14

PJM data center · https://askthegrid.com/assets/facilities/amazon-aws-iad-14

Amazon AWS IAD-14 is a planned Amazon Web Services data-center building at 11801 Brewers Spring Road in Manassas, Virginia, within PJM. Prince William County's Build Out Analysis records 199,003 square feet of planned gross floor area; that figure describes the proposed building, not IT load. No newer exact-building evidence is used to describe the project as operating, and no facility demand, serving substation, or interconnection point is inferred.

## Identity and location

- Operating status: proposed
- Asset scope: building
- Location: 11801 Brewers Spring Road, Manassas, Prince William County, VA
- Operator: Amazon Web Services (exact asset)

## Power and grid context

- Backup generation: 49 MW · approved · exact asset · IAD-14 · as of 2014-05-08 — Permitted diesel emergency-generator capacity associated with IAD-14: one 1,500 ekW generator plus nineteen 2,500 ekW generators; calculated total nameplate capacity is 49 MW. This is backup-generation capacity, not IT load, utility-service capacity, or interconnection capacity.
- ISO/RTO: PJM
- Balancing authority: PJM Interconnection, LLC
- Electric utility: Dominion Energy Virginia

## Development

- Site status: Planned; the current exact-building county record shows both Building Status and Permit Status as Planned, with no occupancy date or year built.
- Site area: 10.05 acres
- Gross floor area: 199,003 square feet
- Buildings: 1
- Construction: Amazon AWS IAD-14 at 11801 Brewers Spring Road is listed in the current Prince William County building record as a planned, site-plan-sourced building with 199,003 square feet of planned gross floor area. The record has no year built, permit case, approved or permitted GFA, or occupancy date. A Virginia environmental permit approved on May 8, 2014 authorized construction and operation of diesel emergency generators at the IAD-14 address, but that authorization does not establish building completion or commercial operation. An older 2024 parcel inventory lists the parcel as an operating data-center parcel with a 115,600-square-foot improvement; because that conflicts with the newer exact-building county record, IAD-14 is not classified here as operating.

## Compute and operations

- Facility classes: hyperscale, cloud
- Workloads: cloud computing
- Operating context: Amazon AWS IAD-14 at 11801 Brewers Spring Road is listed by Prince William County as a planned data-center building with 199,003 square feet of planned gross floor area and no occupancy date. Independent facility data characterizes the same IAD-14 identity as hyperscale, and its intended operating model is AWS cloud computing. The current exact-building government record lists the building as planned, so it should not be treated as operating.

## Data quality

- Prince William County identifies Amazon AWS IAD-14 at 11801 Brewers Spring Road as a planned building with 199,003 square feet of planned gross floor area; the county record contains no planning case number, permit case, approved gross floor area, permitted gross floor area, or occupancy date.
- Third-party directories inconsistently describe IAD14 as operational and report different sizes or addresses. Those claims should not override the county record or be used to describe this building as operating.
- Noise reporting concerns the broader Amazon data-center complex beside Great Oak. The available reporting does not isolate impacts, mitigation, or benefits to IAD-14 alone.
- No exact-site petition, litigation matter, or named community organization beyond the Great Oak Homeowners Association was located.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
