Implementation Consultation for P466: BSC Section N Modernisation

This consultation aimed to provide the BSC Panel with further information to enable it to recommend a revised Implementation Date to the Authority. The Authority directed the Panel to consult on a revised proposed Implementation Date for P466, as the current Implementation Date is no longer appropriate.

We reported to Ofgem that the current P466 Implementation Date was no longer appropriate, as it significantly increased the risk of delivering P415 Facilitating access to wholesale markets for flexibility dispatched by Virtual Lead Parties and Helix, our Market Wide Half Hourly Settlement (MHHS) delivery programme. This is because P415 and Helix require, amongst others, changes to the FAA system. We are modernising the FAA system as part of our Kinnect programme and for reasons of efficiency and cost, will implement P466, P415 and Helix onto the new FAA system. To manage the risk, we plan to implement the new FAA system and P466 at the same time and then subsequently implement the P415 and Helix changes. This is not possible under the current P466 implementation approach.

What is proposed?

The P466 solution involves amending BSC Section N to align it with modern practices and the updated FAA systems. The processes should reduce duplication and make the process more efficient. The proposal also intends to amend irrelevant references that are now redundant, so that BSC parties can more easily understand the BSC Section. The proposed solution will also allow the flexibility for improvements to the FAA systems that would previously have been limited by the legal text. Although this aligns with the new FAA system, this Modification will be a document only change and simply aligns with the new system.
