How the time-to-power window was estimated

Evidence used

Current stage: Operational (furthest stage with documented evidence)[1][2]
Stated date: Next projected milestone: 2030-01-01 (modeled/speculative)[1]
Required: 267 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: H2 2028 – H2 2030

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 30, 2022[1]

First operational: May 1, 2026[1]

Oct 30, 2022[1]
Construction beginning, as can be seen on satellite. Major renovations on western side of the non AI building (PX1), including adding generators and cooling towers.
Jan 31, 2026[1]
Major construction has finished on AI building 1, and AI building 6 has been expedited, as depicted by satellite imagery.
May 1, 202677 MW facility power· 1 buildings operational[1]
Estimated: AI building 1 should be operational. Major construction work finished by January 31, 2026, and the shell looked complete by that date. We estimate after three months the building will be operational.
Jan 1, 2030Projected267 MW facility power· 6 buildings operational[1]
Although official promotional sources estimate the campus to be fully operational in 10-12 years, it is likely to be finished sooner than this given the empirical durations for other data center campuses as well as because AI building 6 has been expedited. The first AI building took approximately 24 months to complete. Assuming construction for a new building starts midway for every building, then the campus will be complete in 4 years for the 5 remaining buildings, since AI buildings 2 and 6 are both underway.
