We published the December MDD data set on Wednesday 9 December 2020, which is due to go live on Wednesday 16 December. This published data set did not contain any TCR changes. The next sets of DNO TCR changes will be published in January 2021. We will continue to monitor the progress of the MDD published for December and listen to feedback from parties.

IDNO Change Requests

We will continue to validate Independent Distribution Network Operator (IDNO) Change Requests for the time being, and will seek approval from the SVG to progress these after we have completed industry testing.

On Monday 14 December we held a workshop with IDNOs to discuss the number of LLFC combinations being requested, and to explain how the MDD processes and timescales work.

We will continue to supporting the IDNOs with their submissions following this workshop.
