time-to-power: greenfield self-build vs wholesale colo (live 50k+ GPU cluster) vs neocloud
~24–36 mo once power is secured (queue adds 4–7 yr in dense hubs) / ~6–12 mo fit-out / days–weeksobserved
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | Each leg is gated differently: queue position and tariff process (self-build), provider capacity + fit-out (colo), available inventory (neocloud). |
| Caveat | 2026 practitioner bands, not commitments — the executed tariff, studies and agreements set any given project's schedule. |

| Source | JLL, 2026 Global Data Center Outlook · Interconnection >4 yr average, ~7 yr Northern Virginia; ~2 yr construction |
| Derivation | Self-build: ~24–36 mo construction once power is secured (CBRE 2026: 18–24 mo groundbreaking-to-commissioning for sub-500 MW; SemiAnalysis practitioner band) — the grid queue in front of it averages >4 yr in major markets and ~7 yr in Northern Virginia (JLL 2026 Outlook), which is why queue position, not construction, gates greenfield. Wholesale colo: ~6–12 mo fit-out of an energized shell (xAI Colossus's 122-day build is the compressed extreme; CBRE reports preleased delivery beyond 12 mo for new shells). Neocloud: days–weeks when capacity exists; reserved capacity books months ahead. |
