Last change recorded — · Last checked 2026-10-05
Jeollanam-do's 3 GW AI data center (Fir Hills / Stock Farm Road, up to $35bn, Nvidia partnership) on the Solar City reclaimed-land site; approved February 2025, completion targeted for 2028, but reporting in July 2026 said detailed plans were still unclear. Separately, the government's National AI Computing Center (2.4 trn won, 15,000 GPUs by 2028) broke ground at Haenam on 2026-08-03. No first-power date published for the 3 GW project. · source ◐ secondary, confidence low
Recorded readiness — 1 of 7 applicable milestones have a dated public record
Gate to first power — target 2028-12-31 (estimate) · path: Hybrid: on-site bridge, then grid · each step must finish its lead time before the target
0 of 5 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.

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 (announced phases from public reporting; rows after today are plans)
Recorded fact No public date for permits in hand, grid supply agreed, new generation online, major equipment on site, building ready for it.
Calculated requirement Grid supply agreed must finish by 2028-03-28; no public date is on record for it. Under the current rule set the recorded dates plus their lead times give a first power no earlier than 2028-12-31 (on the target). This is a floor set by the record, not a forecast.
