Stream Data Centers' Goodyear campus: up to 2 million sq ft and 280 MW critical load at full build-out, fed from an on-site 350 MW APS substation. Phoenix IV is planned for 2029. · source ◐ secondary, 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.

Build-out timeline (Epoch AI; dated status notes with IT power; rows after today are estimates)

2022-10-30—Construction beginning, as can be seen on satellite. Major renovations on western side of the non AI building (PX1), including adding generators and cooling towers.

2026-01-31—Major construction has finished on AI building 1, and AI building 6 has been expedited, as depicted by satellite imagery.

2026-05-0164 MWEstimated: AI building 1 should be operational. Major construction work finished by January 31, 2026, and the shell looked complete by that date. We estimate after three months the building will be operational.

2030-01-01 est.220 MWAlthough official [promotional sources](https://www.streamdatacenters.com/wp-content/uploads/2026/01/SDC-Goodyear-CaseStudy-251218.pdf) estimate the campus to be fully operational in 10-12 years, it is likely to be finis

Recorded fact building ready for it has a recorded date later than the rule-based deadline for a 2026-05-01 first power.

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