How the time-to-power window was estimated
Evidence used
  • Current stage: Operational (furthest stage with documented evidence)[1]
  • Stated date: Next projected milestone: 2027-07-01 (modeled/speculative)[1]
  • Required: 464 MW
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.

Timeline

Construction start: Oct 1, 2021[1]
First operational: Apr 1, 2024[1]
  1. Oct 1, 2021[1]

    Land clearing begins on the eastern half of the site, for Buildings 1-2

  2. Jul 1, 2023[1]

    Building 2 foundation work begins. Building 1 generators seem complete, cooling towers still under construction.

  3. Apr 1, 202478 MW facility power· 1 buildings operational[1]

    Building 1 operational. No visible construction and roads/parking complete around the building. Building 2 chillers are beginning construction. Foundation work begins for Building 3.

  4. Mar 1, 2025156 MW facility power· 2 buildings operational[1]

    Building 2 operational. Parking complete, no more visible construction.

  5. Oct 1, 2025260 MW facility power· 3 buildings operational[1]

    Building 3 operational. Surrounding roads finished, no more visible construction.

  6. Feb 21, 2026260 MW facility power· 3 buildings operational[1]

    Buildings 1-3 are visibly operational, with steam coming out of the cooling towers. Meanwhile Building 4 is extremely close to completion, with all backup generators complete with only 3 cooling towers missing their fans. ~1/2 the generators are installed for Building 5, and the roof is mostly complete (starting to install the final white layer, with the actual roof structure already complete).

  7. May 1, 2026364 MW facility power· 4 buildings operational[1]

    Building 4 operational. No more visible construction, and since only 3 fans needed to be installed since Feburary, operational date was likely soon after. Building 5 roof almost complete.

  8. Aug 5, 2026364 MW facility power· 4 buildings operational[1]

    Confirmation that Building 4 is complete. Building 5 has progressed since February, with a complete roof, all backup generators in place, and five cooling towers in place.

  9. Jul 1, 2027Projected464 MW facility power· 5 buildings operational[1]

    Building 5 operational. The transmission line construction notice that expands site by 100 MW is assumed to be entirely for Building 5, and has an in-service date of July 1, 2027 (page 3). Estimate taken on the safe side based on completion times for Building 3-4 from when roof was complete.

  10. Jun 8, 2022[2]
