Palo Verde West
CAISO ↔ Arizona · Intertie scheduling point
CAISO’s PVWEST intertie scheduling point. Its reading nets published import and export schedules across the balancing-area pairs using this point. CAISO’s network model includes the Palo Verde and Hassayampa 500 kV terminals in Arizona; the marker is at Palo Verde.
Scheduled transfers
Compare each operator’s reading at its stated time. Scheduled transfers and metered physical flow measure different things.

Sources and method
Schedules come from CAISO 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 CAISO. 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.
