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
- Jul 1, 2023[1]
Land clearing begins for the entire site.
Building 1 is operational. This is based on the state of construction on 2025-03-02 as seen on Google Earth, where building shell and external components seems to have been completed, but there is still a lot of construction equipment present. That equipment appears to have been cleared up by this date, 4 months later, with the 2025-09-07 satellite imagery providing an upper bound. Construction has begun on the Building 2 roof, with work beginning on the areas for cooling and generators as well.
Building 2 roof is mostly completed. Building 2's backup generators are almost complete, and cooling is a little more than halfway complete. The Building 2 substation is also under construction.
Building 2 is close to being operational. There is only construction left on the backup generators, which are almost complete. Some equipment is also strewn around the building, especially near the air-cooled chillers. Preparation seems to have begun for Building 3 at the site.
Building 2 is operational. This is estimated based on the close-to-complete construction status from May 2026.
