Formal title: Recommended Changes following an Operational Review of MDD Processes

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


Currently, Market Domain Data (MDD) Change Requests submitted to Elexon (in accordance with BSCP509 ‘Market Domain Data’) are handled through a resource-intensive and error-prone manual process.   This results in unnecessary difficulty and expense for both the parties raising change requests, and for Elexon. In particular, there were several issues arising from version 116 of the MDD release as described in paper SVG61/004. At the Supplier Volume Allocation Group (SVG) meeting on 02 May 2006, the SVG agreed that an operational review of the Market Domain Data Process should be carried out (Paper SVG63/08).   The approach included feedback from a group of industry experts and also from a discussion session at the SVA Forum held on 18 July 2006. The review indicated that a number of changes to BSCP509 are desirable to ensure that the requirements are streamlined, and that all of the forms set out in BSCP509 are efficient and consistent with the information in the MDD database.   Suggested changes were discussed by the SVG at its meeting on 31 October 2006 (SVG69/02) and these are highlighted in CP1190


CP1190 was raised on 4 May 2007. CP1190 was issued for Industry Impact Assessment as part of CPC00604on 4 May 2007.   CP1190 was presented to the SVG for a decision on progression on 3 July 2007. The SVG approved CP1190 for inclusion in the November 2007 Release.
