  • ⚠ No permit record linked to this site yet.
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 2025-09-27 (1.0 years).
  • Stated date: Modeled completion date: 2028-12-31 (modeled/speculative)[1]
  • Required: 1.2 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

Interconnection records

No interconnection-queue record is linked to this site. Of the ISOs we ingest, only NYISO publishes large-load requests; PJM, ERCOT, MISO, SPP and CAISO queues list generation only.

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 27, 2025[1]
  1. Sep 27, 2025[1]

    Land clearing begins for the site

  2. Jan 4, 2026[1]

    Small sections of building foundation construction begins, and land clearing appears to be mostly finished

  3. Mar 23, 2026[1]

    Steel framing and roofing is underway for Building 1.

  4. Dec 31, 2028Projected1.2 GW facility power[1]

    All buildings finished, site is fully operational. Our reasoning is that examples so far take a median of 2-2.5 years to go from land clearing to 1 GW. This suggests around 2028-01-01 here. However, due to delays being more likely than speedups and the fact that this base rate data is still unproven, the more conservative estimate is made. The current state of the site also supports this estimation.
