Change Proposal: CP1493

Add a form and associated process steps to BSCP15 for registering Non-Standard BM Unit configurations

Proposer: ELEXON

Current Phase: Implemented

Categories: CVA, SVA

Responsible Panel Committees: Imbalance Settlement Group (ISG), Supplier Volume Allocation Group (SVG)

Implementation Date: 22 February 2018 (February 2018 Release)


BSCP15 section 3.1 currently states that if a Party wishes to apply for a non-standard BM Unit configuration for the relevant Plant and Apparatus, it must write a letter to BSCCo (ELEXON). This letter must set out the justification and ‘additional information’ that explains why its proposed non-standard configuration should be agreed.

Currently, the BSCP does not detail what ‘additional information’ the Party should provide; what ELEXON then does with that information; or what the next steps are for progressing the non-standard BM Unit configuration application. ELEXON is often asked by Parties what information needs to be included in the letter, or if we can provide a sample or template letter. This highlights a lack of clarity in the process, creating the potential for inconsistency and delays in applications.

This CP will amend BSCP15 in order to create a new form to be used by Parties when applying for non-standard BM Units; change the existing process steps for non-standard BM Unit registrations, so that they require Parties to complete this application form rather than submit a letter; add extra steps to the registration process, reflecting how ELEXON then progresses the non-standard BM Unit application to the ISG for decision; add definitions of Non-Standard BM Unit and Standard BM Unit; and make a number of housekeeping changes, including re-ordering process steps.


CP1493 was raised by ELEXON on 8 September 2017. The CP Progression paper was presented to the ISG and SVG for information at its meetings on 26 September 2017 and 3 October 2017 respectively. The CP was issued for CP Consultation on 9 October 2017, with responses due by 3 November 2017.

CP1493 was approved by the SVG and ISG at its meetings on 5 December 2017 and 11 December 2017 respectively. CP1493 was implemented on 22 February 2018 as part of the February 2018 Release.
