Constrained-on/off costs and volumes

The system operator may on occasion need to dispatch plant out of merit order or, conversely, not dispatch plant that is in the merit order - see clauses 13.192 to 13.212 of the Code for the precise details. Participants are compensated with constrained-on or constrained-off 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. See here  for more information about these files.

What are datasets?

Datasets are collections of files that often contain large volumes of data and are available for immediate download. Dataset users are typically analysts familiar with the electricity industry and have a need to obtain a large set of data or specific data on a regular basis.
