End to reporting of some transparency data to Elexon

As part of the development of Elexon’s new wholesale market data service, the Insights Solution, we did not migrate some data flows from the legacy Balancing Mechanism Reporting Service (BMRS) to the new platform.

 This follows implementation of CP1583 ‘Rationalising publication of European Transparency Regulation (ETR) data on Elexon Systems’.  

These reports have previously been identified as being of minimal value to Elexon’s customers as the data is duplicated in other reports, has had no data reported, or has been superseded by subsequent regulatory changes.

Elexon is no longer required to publish the data flows set out in CP1583

CP1583 was approved by the Imbalance Settlement Group (ISG) in October 2023 for implementation on 1 November 2023. Elexon has not been required to publish the reports set out in CP1583 since 1 November.  

While these datasets have not been migrated to the Insights Solution, we will continue to publish these reports on the legacy BMRS until we switch it off on 31 May 2024.  

Parties will not need to submit some outage reports

For some of the reports relating to outages, Parties normally make their submissions to National Grid ESO’s Market Operation Data Interface System (MODIS). They will be able to stop submitting the data to ESO.  

These reports include:  

  • Planned Unavailability of Generation Units (B1510)   
  • Changes in Actual Availability of Generation Units (B1520) 
  • Planned Unavailability of Production Units (B1530) 
  • Changes in Actual Availability of Production Units (B1540) 

Saving time for companies on reporting

Not having to report this data reduces some of the BSC compliance administration for certain Parties.
