Authority decision to send back CUSC modification proposal CMP379

Share the page

On 9 September 2021, National Grid ESO raised CUSC Modification Proposal (CMP) 379 (‘Determining TNUoS demand zones for transmission – connected demand at sites with multiple Distribution Network Operators (DNOs)’). The CUSC Panel subsequently submitted a Final Modification Report (FMR)1 to us on 8 March 2023. We have decided that we cannot form an opinion on CMP379 based on the FMR submitted and we therefore direct that the FMR is revised and resubmitted.
