AI evidence brief
Summarizes only the evidence on this page. Answers citing anything else are rejected automatically.
How the time-to-power window was estimated
Evidence used
  • Current stage: Under construction (furthest stage with documented evidence)[1]
  • Construction elapsed: Construction documented since 2025-09-18 (1.0 years).
  • Stated date: Next projected milestone: 2026-12-30 (modeled/speculative)[1]
  • Required: 300 MW
Assumptions
  • From “Under construction”, large loads have typically taken 0.5–2 more years to first power (editorial range; see Methodology).
  • Construction to first power typically takes 1.25–2.5 years.
  • The window is a range of plausible outcomes under these assumptions, not a forecast. It moves as new filings, queue updates or imagery arrive.
Window: H1 2027 – H1 2028

Utility, ISO and nearby assets are derived from the site's location. Proximity to a substation or line doesn't establish the interconnection; that needs a utility filing or interconnection-queue record. Queue requests are applications, not commitments — most never reach operation.

Timeline

Construction start: Sep 18, 2025[1]
First operational: Dec 30, 2026[1]
  1. Sep 18, 2025[1]

    Site grading and civil works begin.

  2. Nov 29, 2025[1]

    Foundations of Building 1 are visible.

  3. Jul 30, 2026[1]

    Building 1 shell is complete, with rooftop units installed, and most air-cooled chillers in place in a ground yard to the north. Most of the 120 backup diesel generators are also in place. Substantial progress since Nov 2025, still under construction and not yet energized.

  4. Dec 30, 2026Projected244 MW facility power· 1 buildings operational[1]

    Building 1 Phase I is operational: 168 MW critical IT power (244 MW gross), running Google TPU v7 (chip type inferred, tagged likely). We estimate ~Dec 2026, about 3 months later than the disclosed target, because the site is shell-complete but not yet energized as of the Jul 2026 image. Disclosed target: Cipher 2025-09-25 PR states the 168 MW critical IT load is "expected to be delivered by September 2026."

  5. Apr 30, 2027Projected300 MW facility power· 1 buildings operational[1]

    Building 1 Phase II is operational: 207 MW total critical IT (300 MW gross). Phase II adds 39 MW critical IT (see Cipher 2025-11-20 PR). We estimate ~Apr 2027, about 3 months later than the ~Q1 2027 target, based on construction progress.
