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.

The CCDG will build 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
• identifying, and overseeing drafting of, the changes needed to Industry Codes and subsidiary documents to enable the TOM

For each CCDG meeting, we produce a Headline Report summarising its discussions (see ‘Meetings’ below). We will also publish more information as the group’s work progresses. 

What’s new?

Due to a variety of factors including COVID-19, we are currently re-planning the CCDG’s activities with Ofgem. The work plan published on this page is therefore out of date, although it is still a useful overview of the scope and sequencing of the group’s deliverables. We will publish a revised plan as soon as possible. In the meantime, the diagram below is our latest view of the key milestone timings.

Since March 2020, all CCDG meetings have been held remotely and this will continue until at least the beginning of 2021. See here for more information on how we are approaching remote meetings.
