Constrained on-off costs by month
The monthly dollar cost of constrained on/off payments by participant, location, trading period, and constraint type
The system operator may on occasion need to dispatch plant out of merit order, ie dispatch plant in a way that does not result in a least cost dispatch - see clauses 13.192 to 13.212 of the Code for the precise details. Participants are compensated with constrained-on (when offered price exceeds the clearing price) or constrained-off (clearing price exceeds the offered price) payments when this occurs.
A file is published each month that contains constrained-on/off costs and volumes by participant, location, trading period, and constraint type.
