Defaulting Data Aggregators

Default Data used for Half Hourly Data Aggregator

Following an incident with the Data Transfer Service (DTS) on 29 July 2019, there was a delay in some files being sent to the Supplier Volume Allocation Agent (SVAA).  ELEXON did not receive the below files from one Half Hourly Data Aggregator (HHDA) in time for the Volume Allocation Run today.

Default data has been used for the dates as shown in the table below:

II HH 24/07/2019 23/07/2019 II NEEB H, M
SF HH 09/07/2019 09/07/2019 II NEEB A


Any Suppliers who believe they are impacted should contact their DA directly, however other Parties may be affected to a small degree through their GSP Group Correction Factors.

If you have any questions relating to this issue, please contact the BSC Service Desk (
