Change Proposal: CP1480

Creation of a new authorisation category for corrections to BOA related data

Proposer: National Grid Electricity Transmission Plc

Current Phase: CPC Consultation

Lead Analyst: Pritesh Mistry

Categories: CVA, SVA

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

Implementation Date: Targeted for 29 June 2017 (June 2017 Release)


The BSCP18 ‘Corrections to Bid-Offer Acceptance Related Data’ is ambiguous on who may authorise corrections to Bid-Offer Acceptance (BOA) data.  This lack of clarity is creating problems for the Transmission Company (TC) when trying to identify the right individual to contact and can cause delays. These delays could mean that corrections to data are not made by the Settlement Final (SF) Run causing incorrect data to enter Settlement.

CP1480 proposes the creation of a new authorisation category specifically for this activity. Details of individuals in this new category would be made available to the TC for the purpose of seeking consent for corrections to BOA related data to be made.



CP1480 was presented to the ISG on 13 December 2016 and was presented to the SVG on 3 January 2017. CP1480 was issued for consultation on 9 January 2017 and closed on Friday 3 January 2017 at 5pm.It will now be presented to the ISG and SVG on the 21 February 2017 and 28 February 2017 respectively.
