P473 Correcting inconsistencies in the P415 Legal Text

Modification P415 ‘Facilitating access to Wholesale Markets for flexibility dispatched by Virtual Lead Parties’ seeks to allow independent aggregators to sell customers’ flexibility into Wholesale Markets. Independent aggregators wishing to do this will be required to accede to the BSC in the new role of Virtual Trading Party (VTP). Ofgem has approved this Modification for implementation on 7 November 2024 as part of the standard November 2024 BSC release.

Elexon has received industry feedback on the Legal Text post Ofgem approval on 6 October 2023, as well as internal feedback during work with service providers to design the system changes required to implement Modification P415, and this has revealed that the P415 Legal Text does not correctly describe the intended solution for P415 as well as some inconsistencies and omissions.
