Change Proposal: CP1480

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

Proposer: National Grid Electricity Transmission Plc

Current Phase: Committee Decision

Lead Analyst: Pritesh Mistry

Categories: CVA, SVA

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

Implementation Date: 2 November 2017 (November 2017 BSC Systems 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.



The progression paper for CP1480 was presented to the ISG on 13 December 2016 and was presented to the SVG on 3 January 2017. It was then issued for consultation on 9 January 2017, which closed on Friday 3 February 2017.

CP1480 was presented to the ISG on the 21 February 2017 for decision. ISG have asked for information on whether a shared mailbox can be used for an Authorised Person and if the list can be managed via the ELEXON portal. As a result, they have deferred the decision for CP1480.

This was presented to SVG for decision on 28 February 2017 and similarly they decided to defer CP1480 for a month. They asked if we could explore a number of other soloutions and present the options at the next SVG meeting in April.

This will be presented to ISG on 28 March 2017 to discuss if alternative soloutions and improvements can be made to CP1480 or if they should  accept/reject as CP1480 as it currently stands. Please note that if alternative soloutions were chosen then another industry consultation is likely.

In addition, due to ISG and SVG choosing to defer the decision and the likelihood of an additional consultation, the implementation date has been moved to November 2017 because June 2017 is no longer possible.
