Elexon confirms P462 Workgroup meeting 18 held and full Assessment Procedure timetable through May 2027 unchanged

The 22 September 2026 Elexon P462 modification page confirms that Workgroup meeting 18 took place on 16 September 2026 (a meeting not previously reflected in the tracked timetable) and reconfirms the remainder of the published Assessment Procedure schedule without alteration: Workgroup meeting 19 on 13 October 2026, Assessment Phase Consultation running 19 November–9 December 2026, Assessment Report to BSC Panel on 11 February 2027, Report Phase Consultation running 22 February–23 March 2027, Draft Modification Report to BSC Panel on 13 May 2027, and Final Modification Report to the Authority on 17 May 2027. No topic summary for Workgroup meeting 18 has yet been published on the page, unlike prior meetings.

The absence of any timetable slippage or further extension request signals that, after two prior extensions (12 months in Nov 2024 and 4 months in Dec 2025) and completion of the CEPA CBA in April 2026, the Workgroup is now converging toward finalising its recommended solution ahead of the Assessment Phase Consultation. This matters for BSC Parties and support-scheme generators because the consultation in November-December 2026 will be the first formal opportunity for wider industry to respond to whatever solution (original Section T 3.11 amendment or an Alternative Solution) the Workgroup settles on, directly shaping how CfD/RO-supported generators will price Balancing Mechanism bids and how consumer balancing costs are calculated going forward.

The confirmation that Workgroup meeting 18 occurred on schedule (16 September 2026) with the full downstream timetable intact suggests the Workgroup has avoided a third extension, which would have been a plausible risk given the complexity flagged by two earlier extensions and REMA-interaction discussions from meeting 4. The unpublished topic for meeting 18 is notable given that all prior meetings (1 through 17) have topic descriptions logged on the page; this could indicate the meeting addressed sensitive or still-evolving content, such as finalising choice between the base Section T 3.11 amendment and the 'Alternative Solution' floated at meetings 7, 16 and 17, ahead of the Assessment Phase Consultation. If the timetable holds, the November-December 2026 consultation will be the key near-term signal of which design direction the Workgroup has settled on.
