Dashed boxes are based on proximity only and do not establish which asset serves the site.

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

No on-site, behind-the-meter or dedicated generation found in sources.

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.
