Outcome of request for an urgent review of proposed changes to Connection and Use of System Code, CMP473 Clarification of contract updates required with a Gate 2 Modification Offer.
Details of outcome
We have disagreed with the Panel’s view that CMP473 should be progressed on an urgent basis. In reaching our decision, we have considered the details of the Proposal, the justification for requesting urgency, the views of NESO, and the views of the CUSC Panel. We are not satisfied that the issue is imminent, urgent, and could have significant commercial impacts on affected parties. This letter sets out our reasoning.
Code modification description
On 13 April 2026, RWE raised CUSC modification proposal CMP473, which seeks to clarify which updates to Existing Agreements are required to be implemented through a Gate 2 Modification Offer. The Proposer has indicated that, under current arrangements, Gate 2 Modification Offers may not consistently reflect updates to Existing Agreement appendices, including Appendix J, and that this lack of clarity could result in connecting Users being issued with offers that do not accurately reflect the contractual position.
