PJM–New York AC interface
NYISO ↔ PJM · AC with phase-angle regulation
Every AC tie between PJM and New York, scheduled as one interface. The phase-angle regulators at Ramapo steer how much of it flows where.
Operator readings
Compare each operator’s reading at its stated time. Scheduled transfers and metered physical flow measure different things.

Sources and method
Readings come from NYISO and PJM interface readings. Each value is shown with its operator and source time; direction is normalized from that operator’s sign convention toward or away from NYISO. A rating describes the equipment; an operator’s posted directional limit, when available, is a separate operating value. The map point identifies a sourced terminal or crossing where available, or a representative connection point; it does not trace the full route.
