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. 

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.

This Modification proposes 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.


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. The responses have been published below.

The Assessment Report was presented to the BSC Panel on 11 April 2019. 

P372 was submitted for Report Phase Consultation on 16 April 2019, with responses due by 5pm Wednesday 1 May 2019.

The Report Phase Consultation did not receive any responses, questions or further comments. The consultation was active for a standard 10 Working Days, and industry were reminded to respond.

The BSC Panel considered the Draft Modification Report at its meeting on 9 May 2019 and approved the P372 Solution under Self-Governance.

P372 was subject to a 15 Working Day appeal window, which closed on Thursday 30 May 2019. There were no appeals recieved, therefore P372 will be implemented on 27 June 2019 as part of the June 2019 BSC Release.
