Elexon confirms P518 Report Phase Consultation on ABSVD data provision for CLASS has closed

The Elexon consultation page for BSC Modification P518 now shows the Report Phase Consultation status as 'Closed', confirming that the consultation window (issued 18 August 2026, response due 1 September 2026) has ended as scheduled, with the same enabling-only scope requiring BSCCo to provide NESO with ABSVD-related data for CLASS.

Closure of the Report Phase Consultation moves P518 from the input-gathering stage into the assessment stage ahead of the Draft Modification Report to BSC Panel, a necessary step before any Self-Governance decision can be made on this enabling data-provision obligation that underpins NESO's C9 ABSVD methodology for CLASS.

The consultation closing on schedule with no indication of extension or scope amendment suggests the enabling-only framing is proceeding without significant industry pushback, consistent with expectations for a low-cost, narrowly scoped Self-Governance candidate; analysts should watch the forthcoming Draft Modification Report for any summary of consultation responses that could reveal disagreement over data granularity or timing before the Self-Governance objection window opens.
