AI evidence brief
Summarizes only the evidence on this page. Answers citing anything else are rejected automatically.
How the time-to-power window was estimated
Evidence used
  • Evidence: No dated stage evidence found.
Assumptions
  • An estimate needs at least one dated development, permit, grid or construction record.
  • The window is a range of plausible outcomes under these assumptions, not a forecast. It moves as new filings, queue updates or imagery arrive.

Interconnection records

No interconnection-queue record is linked to this site. Of the ISOs we ingest, only NYISO publishes large-load requests; PJM, ERCOT, MISO, SPP and CAISO queues list generation only.

On-site & dedicated generation

  • Customer-owned, behind-the-meter, dispatchable generation (required by the utility tariff)[1]

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.
