STACK's Prince William County campus: ten data centers and 420 MW on 200 acres, fed by two dedicated 300 MW on-site Dominion substations, in Northern Virginia's power-constrained market. The county rejected a separate STACK rezoning application. · source ● primary, confidence medium

Lead-time assumptions

Site secured 15 months before first power — Land under control and campus announced. Rarely binding; shown for context.
Permits in hand 0 months before first power — Final air and siting permits. Operators often energize on standard or temporary authorisations and receive the major permit later; flagged only when the permit lands more than 6 months after first power or is missing for an on-site plant.
Grid supply agreed 9 months before first power — Interconnection or large-load agreement approved. Observed median 7 months before first power; the physical works (substation, lines) run in parallel with construction.
Substation and lines energized 2 months before first power — Utility delivery point live; final tests before the load is taken.
New generation online 1 months before first power — Utility plant or on-site plant generating; needed just before energization when the grid cannot carry the load alone.
Major equipment on site 6 months before first power — Turbines, transformers, switchgear delivered; installation and commissioning take the remaining months.
Construction started 24 months before first power — Groundbreaking of the building that gives first power. Observed 4-26 months for recent AI campuses; Meta's redesigned campuses took 35-58.
Building ready for IT 0 months before first power — First building ready for IT. 'Complete' or 'opened' is usually reported after first power; flagged only beyond 3 months.
Full build-out complete -12 months before first power — All announced buildings operational. Comes after first power by design; context only.
Water supply secured 12 months before first power — Water rights, municipal agreement or desalination contract in hand. Context only; one of the feasibility items.
Financing closed 12 months before first power — Project financing, anchor lease or committed capital announced. Context only; not applicable when the owner is a hyperscaler building on its balance sheet.

2028-01-01 est.348 MWEstimate: All 6 AI data center buildings will be finished in 2028, assuming a groundbreak-to-operational timeline of 18-24 months. One is complete, three are clearly under construction, and the last two data centers are

Recorded fact The site is energized.

Calculated requirement Energized; watch the build-out timeline for the next buildings.
