Code Change and Development Group (CCDG)

The CCDG is one of three industry working groups which Elexon is chairing and providing with technical leadership to support Ofgem’s Significant Code Review on Electricity Settlement Reform.

CCDG’s role, outputs and timetable

The CCDG is building on the Target Operating Model (TOM) for Market-wide Half Hourly Settlement, as delivered by the Design Working Group in August 2019, by:

  • developing further detailed areas of the TOM design
  • developing further detail on the transition approach for migrating different types of Meters to the new Settlement arrangements, and on the ‘run-off’ of the existing Non Half Hourly Settlement arrangements
  • identifying, and overseeing drafting of, the changes needed to Industry Codes and key subsidiary documents to enable the TOM

The diagram below shows when the CCDG plans to consult industry for the different stages of its work, as well as when it intends to issue its final report to Ofgem. For each CCDG meeting, we also produce a Headline Report summarising its discussions (see ‘Meetings’ below). Since March 2020, the CCDG has been meeting remotely.

What’s new?

On 17 December 2020, we issued the CCDG’s consultation on its detailed Target Operating Model design and its identified impacts on Industry Codes. We have since extended the consultation deadline to 29 January 2021. We also held a webinar on 13 January 2021 to talk through the consultation and answer any questions.

The consultation is your opportunity to give your views on the essential data items, processes and Industry Code changes needed to deliver Market-wide Half Hourly Settlement.
