Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

The Loudoun County Planning Commission voted unanimously to recommend denial of application LEGI-2024-0074 on July 23, 2026; the application still awaits a Board of Supervisors decision.
Underlying source
Source notes
Application LEGI-2024-0074. Ten data center buildings up to 100 feet tall, three electrical substations and a backup power storage facility on the east side of Evergreen Mills Road south of Watson Road, in Loudoun's Transition Policy Area near Goose Creek. Rezoning sought from Transitional Residential-10 to Industrial Park. Sources give different footprints — Loudoun Now reports 325 acres and 3.25 million sq ft; Loudoun Wildlife Conservancy reports 362 acres and up to 3.5 million sq ft — so no land area is recorded here rather than picking between them. The southern half comprises 13 parcels of the Spring Valley subdivision with existing single-family homes; one parcel holds an 1880s house and a family cemetery.
Loudoun Wildlife Conservancy describes proposed natural gas-powered hydrogen fuel cells with on-site battery storage and three substations; Loudoun Now reports Tier 4 generators throughout. No generation capacity figure has been published.
