Authority decision to send back CUSC modification proposal CMP441
Share the page
On 23 December 2024, the Final Modification Report for Connection and Use of System Code (CUSC) Modification Proposal CMP441: 'Reducing the credit risk of supplying non-embedded hydrogen electrolysers' was submitted to the Authority for decision.
It is our decision that we are unable to properly form an opinion on CMP441 based on the Final Modification Report as submitted to us. We are therefore sending the proposal back to the CUSC Panel for further consideration.
