The Balancing Mechanism Reporting Service (BMRS) is the primary channel for providing operational data relating to Great Britain’s (GB) Electricity Balancing and Settlement arrangements, as well as REMIT and European Transparency Regulation data. It’s used extensively by market participants to help make trading decisions and understanding market dynamics, and acts as a prompt reporting platform as well as a means of accessing historic data. The BMRS has a wider user base both within and outside of the energy industry and includes traders, regulators, industry forecasting teams and academics.

The level of detail within BSC Section V is inconsistent with other sections of the Code which instead use CSDs to provide detail, leading to extended timescales involved in assessing, progressing and implementing a relatively minor and low impact BMRS change as a Modification under current arrangements.

Furthermore, because minor BMRS changes are unlikely to materially impact BSC Parties, these changes could be released more frequently than current BSC Systems Release accommodations. These visible and elongated timescales have led to recent public criticism of the process with some industry participants now looking to make their own publication arrangements rather than using the BMRS.

This would have a detrimental effect of potentially fragmenting market information across platforms and making the act of accessing market information more arduous and reducing transparency with a further adverse effect on competition.

This Modification aims to streamline BSC Section V – ‘Reporting’ by moving a selection of reports, to be determined by the Modification Workgroup, currently set out in Annex V-1, to the Reporting Catalogue and/or IDDs; or alternatively place certain reports in a separate BSC Panel controlled document, facilitating the opportunity to progress a Change Proposal in place of the requirement to progress a Modification.

It is further proposed that the operational processes followed by ELEXON to determine the scope and content of BSC Systems Releases are reviewed to determine whether new and amended publication requirements could be delivered outside of the normal release schedule.


P372 was raised by the BSC Panel on 13 September 2018. The Initial Written Assessment was presented to the Panel on 13 September 2018 and the Panel agreed to progress the Modification to the Assessment Procedure. 

The first industry Workgroup was held on 15 November 2018 where a solution was agreed.

The second industry Workgroup was held on 18 December 2018 to gather Workgroup initial views on the proposal before issuing the Assessment Consultation.

ELEXON issued the Assessment Procedure Consultation for a 15 Working Day window on 27 February 2019.

Next Events

The Assessment Procedure Consultation will finish at 5pm on Tuesday 19 March 2019.
