View P463 Report Phase Consultation on Introducing a Standard Change Process

P463 Report Phase Consultation on Introducing a Standard Change Process

P463 seeks to introduce a new change process – a ‘Standard Change’ process – into the BSC arrangements that would allow for certain, low risk, predictable and repeatable pre-authorised changes to be implemented without following the existing Change Proposal or Modification procedures. This should reduce the burden on industry and Elexon; allowing them to focus on higher value activities.

P476 Report Phase Consultation on Exemption from MHHS Requirements for Smart Market Segment Supplier Qualification

P476 seeks to allow the Performance Assurance Board to have the authority to exempt Suppliers from Smart Segment Qualification obligations. This would allow a Supplier operating in the advanced market segment (that does not have the system, processes or controls in place to meet these obligations) without a specific cost associated to be exempted from Design, Test and Build.

P475 Report Phase Consultation on Allowing All Storage Sites to set and fix their own Production/Consumption Flags

The purpose of this Modification is to address the issue of storage BM Units flipping between Production (P) and Consumption (C) statuses. This flipping leads to significant financial challenges for parties managing large storage units. The proposal seeks to allow storage BM Units to fix their P/C status, thereby mitigating these challenges.

View P469 Report Phase Consultation on Credit Default ECVNs Refuse and Rejection Periods

P469 Report Phase Consultation on Credit Default ECVNs Refuse and Rejection Periods

P469 proposal seeks to delay the Credit Default Refusal and Rejection Periods. This change would give parties a two-hour window from the Level 2 Credit Default notification until the time when any Energy Contract Volume Notifications (ECVN) related to a defaulting party are rejected.

To implement the proposed Solution, this Modification aims to change BSC Section M, 3.3.3 a (i) and (ii).

P471 Report Phase Consultation relating to the procurement of BSC Agents

P471 seeks to allow more flexibility in the requirements for procurement of BSC Agents, to allow the option of having these systems operated by the service provider who developed them (at least for the duration of the transition period), while the currently-appointed Supplier Volume Allocation Agent (SVAA) continues to operate legacy processes.

Elexon have re-issued this P471 Report Phase Consultation, following feedback from a P471 webinar held on 27 June 2024. P471 now includes some alternative legal text. We have included two additional consultation questions as a result.

The alternative legal text has amended Section E2.7.1, E2.7.3 and a new paragraph E 2.7.1A has been included, which focuses on what the Appointment Approach Statement should include. It now requires a brief description, where an appointment, rather than a procurement of a BSC Agent is proposed to require:

  • Rationale for the approach;

  • Considerations of commercial and other advantages, including value for money assessments, where practical and proportionate; and

  • The duration and overall amounts involved in such arrangements

P469 Assessment Procedure Consultation on Credit Default ECVNs Refusal and Rejection Periods

P469 seeks to delay the start of the Credit Default Refusal Period and Credit Default Rejection Period for Energy Contract Volume Notifications (ECVNs) and Metered Volume Reallocation Notifications (MVRNs) where acceptance of said ECVNs and MVRNs would increase a BSC Party’s Energy Indebtedness.

This Assessment Procedure Consultation was issued on 14 June 2024 and will close at 5 pm on Friday 28 June 2024.

View Implementation Consultation for P466: BSC Section N Modernisation

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.

View P473 Correcting inconsistencies in the P415 Legal Text

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.

Send Back Consultation on P461: Accurate Reporting of Customers Delivered Volumes to Suppliers

Ofgem issued a Send Back Direction on P461 ‘Accurate Reporting of Customers Delivered Volumes to Suppliers’ to the BSC Panel on 8 May 2024, as it was unable to form an opinion on whether or not P461 should be approved.  The Panel approved the draft Send Back Process at its meeting on 9 May 2024. 

The Send Back Consultation was issued on 13 May 2024 and will close at 5pm on Friday 24 May 2024.
