Cottonwood 230 kV
CAISO ↔ Sacramento area · Intertie scheduling point
CAISO’s CTW230 intertie scheduling point. Its reading nets published import and export schedules across the balancing-area pairs using this point. The marker is at the named Cottonwood substation.

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.
