Formal title: Housekeeping Change to CoPs 1, 2, 3 and 5 following P266

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


P266 ‘Improving the allocation of Reactive Power flows between Import and Export Metering Systems’ was implemented on 23 February 2012 as part of the February 2012 BSC Release. This introduced additional paragraphs to Codes of Practice (CoPs) 1, 2, 3 and 5. This had the effect of incrementing the numbering of the ‘Overall Accuracy’ section in each of these CoPs from 4.2.1 to 4.3.1. However, other sections within these CoPs continue to incorrectly reference the ‘Overall Accuracy’ sections as 4.2.1 and not 4.3.1.

This change proposes to amend this manifest error, to prevent the risk of confusion and inconsistencies.


Elexon raised CP1470 on 12 August 2016. The CP Assessment Report was presented to the Imbalance Settlement Group (ISG) on 20 September 2016, and to the Supplier Volume Allocation Group (SVG) on 4 October 2016.

The ISG and SVG approved CP1470 for implementation on 23 February 2017 as part of the February 2017 BSC Systems Release.
