CMP397: Consequential changes required to CUSC Exhibits B and D to reflect CMP316 (Co-Located Generation Sites)
What is being proposed
CMP316 makes changes to Section 14 of the CUSC. CMP397 facilitates CMP316 and proposes consequential changes to CUSC Exhibits B & D
Current status
The Panel met on 30 September 2022 and agreed that it goes straight to Code Administrator Consultation. Code Administrator Consultation was issued at the same time as the CMP316 Code Administrator Consultation and was run from 4 October 2022 to 5pm on 1 November 2022 and no responses were received. Draft Final Modification Report was presented to November 2022 Panel for Panel recommendation vote. 3 Panel Members noted that changes to the legal text for CMP316 WACM1 are required as the legal text does not reflect the intent of CMP316 WACM1. Therefore Panel, under CUSC 8.23.4(iv), asked for the Workgroup (date TBC) to be re-formed to update the legal text for CMP316 WACM1 and at the same time update the worked example (Annex 8) as to how CMP316 WACM1 works, which will help industry understanding. Panel will need confirmation that Workgroup have agreed the above and then a 2nd Code Administrator Consultation (full 15 Working Days given the extent of the Legal Text changes) will be issued specifically on the updates to CMP316 WACM1. Following conclusion of the 2nd Code Administrator, the Draft Final Modification Report will be re-presented to Panel for their recommendation vote. Given its interaction with CMP316, the CMP397 recommendation vote will also be delayed to when the CMP316 Draft Final Modification Report is re-presented to Panel. The Draft Final Modification was submitted to the May CUSC Panel for Panel recommendation vote. At the May 2024 CUSC Panel, the Panel recommended unanimously that the Proposer’s solution better better facilitates the CUSC Applicable Objectives. CMP397 expected decision date of 24 January 2025 (previously 29 November 2024). (06/05/2025) The expected Authority decision date is 30 September 2025.
Details
Timeline
Analysis
CMP397 makes technical changes to CUSC exhibits to support CMP316's co-located generation rules. The modification received unanimous panel support in May 2024 and awaits Ofgem decision by September 2025. This is administrative housekeeping required to implement the substantive co-location framework.
Why it matters
Pure administrative follow-through — the real market impact sits with CMP316 itself. This demonstrates how minor code modifications can take years to clear governance hurdles even when uncontroversial.
