1 GW+ campus in New Albany. Behind-the-meter supply from Williams' Socrates South gas plant (about $1.6bn, OPSB-approved; 200 MW firm, 258 MW at design ambient), construction from Q3 2025 with completion estimated Q3 2026, plus AEP grid service; Meta also contracted more than 2.1 GW from Vistra nuclear plants. Reported in September 2025 as due online the following year; Epoch records first power in October 2025. · source ◐ secondary, confidence medium
Recorded readiness — 1 of 6 applicable milestones have a dated public record
Gate to first power — target 2025-10-14 (estimate) · path: Hybrid: on-site bridge, then grid · each step must finish its lead time before the target
1 of 1 required steps have a public date. Red = recorded date past the rule-based deadline · grey "no public date" = required step without a record · green = on record in time · context steps never colour.

This site is energized; lights only show how its recorded steps compared with the lead times.
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.

Build-out timeline (Epoch AI; dated status notes with IT power; rows after today are estimates)
Recorded fact new generation online has a recorded date later than the rule-based deadline for a 2025-10-14 first power.
Calculated requirement Energized; watch the build-out timeline for the next buildings.
