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: Operational (furthest stage with documented evidence)[1]
  • Stated date: Next projected milestone: 2027-02-09 (modeled/speculative)[1]
  • Required: 1.01 GW
Assumptions
  • From “Under construction”, large loads have typically taken 0.5–2 more years to first power (editorial range; see Methodology).
  • 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 – H2 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.
