How the time-to-power window was estimated

Evidence used

Current stage: Under construction (furthest stage with documented evidence)[1]
Stated date: Requested in-service date (NYISO 1484): 2028-05[1]
Required: 300 MW

Assumptions

From “Under construction”, large loads have typically taken 0.5–2 more years to first power (editorial range; see Methodology).
Stated dates slip; the window allows up to 0.75 years past the stated date at this stage.
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 – H1 2029

Capacity figures are nameplate or contracted; annual consumption is a labeled model estimate, not metered data.

Grid & electricity

Contracted / committed power: Not yet sourced

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.
