PJM interconnection queue

A PJM queue substation page has the same name: Brunot Island (PA) — 4 queue requests filed, 0 active.

Same name and state (weaker). Matched on name and state: the utility that presented this substation operates in one state, and every queue filing at a substation of the same name is in that state. No transmission owner is recorded on those filings, so this is a weaker match than one on owner. Not verified as the same facility.
