Data source
The settlement data published here is calculated and published by the Settlement Administration Agent (SAA) and Central Data Collection Agent (CDCA) as part of the Central Systems settlement process.
The SAA-I014 (subflow 2), CDCA-I029, CDCA-I030 and CDCA-I042 data flows are sent to Elexon, National Grid ESO and can be sent to BSC Parties and non-BSC Parties on request.
Elexon has reformatted the data from these data flows into .csv here to be easier to use.
