How the time-to-power window was estimated
Evidence used
  • Current stage: Announced (furthest stage with documented evidence)[1]
  • No public grid record: No interconnection request or utility contract found; adds uncertainty to the upper bound.
  • Required: 77 MW
Assumptions
  • From “Announced”, large loads have typically taken 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.
Window: H2 2028 – H2 2032

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

  • On-site natural gas generators (backup power, demand response and ancillary services)[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.
