Severity = Σ |shadow price| over bound hours ($/MWh·h). This ranks how
hard each constraint bound, not settled congestion rent (rent requires
constraint flow MW, which CAISO does not publish here). Click a row to
locate it on the map.
When a transmission line or intertie is taken out of service (for maintenance,
or forced by a fault), the grid can move less power along that path — which is
often why a nearby constraint binds and congestion spikes. Each entry
below is a facility with a planned or forced outage in the next 7 days and how
much transfer capability (MW) it removes. Source: CAISO OASIS TRNS_OUTAGE.
A constraint flagged outage? in the Constraints
tab shares equipment-name tokens with one of these outages — a lead worth checking,
not a proven cause.
