Change Proposal: CP1312

Use of Gross Volume Correction in Post Final Settlement Runs

Proposer: ELEXON

Current Phase: Implemented

Lead Analyst: Bu-Ke Qian

Category: SVA

Responsible Panel Committee: Supplier Volume Allocation Group (SVG)


One of the features of GVC is an ‘Error Freezing Reading’. BSCP504 only covers the application of this technique outside the Trading Disputes process. Previously, ELEXON has issued guidance to the effect that an ‘Error Freezing Reading’ may be deemed in the current Post Final Settlement Run (PFSR) window, in the event that the relevant Metering System is subject to a Trading Dispute (and a PFSR has been scheduled for the relevant GSP Group). However, the Trading Disputes Committee (TDC) has recently agreed that its preference is for ‘Error Freezing Readings’ to be deemed at the RF boundary in all circumstances, and not to allow these readings to be deemed at a PFSR. CP1312 proposes to amend Section 4. 14 of BSCP504 to deliver the TDC’s preferred solution.


CP1312 was raised on 28 August 2009. CP1312 was issued for Industry Impact Assessment as part of CPC00668. The SVG approved this CP on 3 November and was implemented  as part of the February 2010 Release.
