CP1407 – Updates to current LLF audit templates

Formal title: Updates to current LLF audit templates

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


CP1407 proposes to create a set of compulsory templates with consistent formatting for the Licensed Distribution System Operators (LDSOs) to complete as part of the annual Line Loss Factor (LLF) audit. As such amendments have been made to the current BSCP128 Appendices and an additional three Appendices have been added.


CP1407 was raised by Elexon on 3 February 2014. CP1407 was issued for CP Impact Assessment on 3 February 2014, with responses due back on 28 February 2014.

Elexon  addressed respondents’ comments and concerns received from the CP Impact Assessment and identified that the changes required would have a material impact on the CP1407 solution. Amendments would include making the BSCP128: Appenidx 5 template mandatory and the BSCP128: Appendix 9 template optional which differs to what was originally proposed for both templates to be mandatory. CP1407 v2.0 was subsequently raised and issued for CP Impact Assessment  on 7 April 2014 in order to obtain industry views on the revised solution.

CP1407 v2.0 was approved by the ISG on 27 May 2014 and the SVG on 3 June 2014 for implementation on 26 June 2014 as part of the June 2014 BSC Systems Release. The changes to the BSC Baseline Statement were approved by the Panel at its meeting on 12 June 2014.
