Change Proposal: CP1479

Updates to the Defined Metering Points in Codes of Practice 1, 2, 3, 5 and 10

Proposer: ELEXON

Current Phase: Committee Decision

Lead Analyst: Giulia Barranu

Categories: CVA, SVA

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

Implementation Date: 2 November 2017 (November 2017 Release)


On 6 February 2014 ELEXON raised Issue 54 ‘Discrepancies between the points of measurement required in the BSC and the CoPs and the physical points of connection’. ELEXON presented the Issue 54 Report (BSC Panel 225/13) to the BSC Panel on 12 June 2014. The Issue 54 Report highlighted issues with three Defined Metering Points (DMPs) in Codes of Practice (CoPs) 1, 2, 3, 5 and 10. This CP proposes to:

  • change the DMP between a Distribution System of a LDSO (with no other parties connected) and the Transmission System to the point of connection;
  • change the DMP for where Generating Plant connects to the Transmission System to be the point of connection; and
  • make the DMP between an External Interconnector and the Transmission System the point of connection, rather than specify all the existing External Interconnectors.


CP1479 was raised by ELEXON on 23 November 2016. It will be presented for decision to the ISG and SVG at their meetings on 21 of February and 28 of February respectively.
