This open letter sets out our approach to the prioritisation and sequencing of decisions in respect of current in-progress proposals to modify the sections of the Connection and Use of System Code (“CUSC”) that relate to Transmission Network Use of System (“TNUoS”) charges. There continues to be a significant number of CUSC Modification Proposals (“CMPs”) in this area, with several of those proposals being either dependent on, or materially affected by, each other.
We consider it appropriate to adapt our decision-making timelines to ensure effective sequencing of our decisions in respect of these changes, and we will work with the CUSC Panel on the prioritisation of proposals still in the industry-led process, ideally based in part on the degree to which those proposals interact with each other. We believe that proper sequencing of our decisions will support: i) stability in the charging regime; ii) the retention of locational investment signals; and iii) predictability in charges themselves.
