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 2025-12-04 (0.8 years).
  • Stated date: Next projected milestone: 2028-12-31 (modeled/speculative)[1]
  • Required: 1.4 GW
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 2028 – H2 2029

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.
