Time-to-power · verification · interconnectionPower reality
- ⚠ Announced 150 MW is 2.0× the 75 MW documented by grid, construction or operating records.
- ⚠ No recorded land acquisition found.
How the time-to-power window was estimated
- From “Interconnection agreement / service contract”, large loads have typically taken 0.75–2.5 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.

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.
