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.

Implementation Consultation for P466: BSC Section N Modernisation

This consultation aims to provide the BSC Panel with further information to enable it to recommend a revised Implementation Date to the Authority. The Authority has 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.

P461 Send Back Consultation

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.

P463 Assessment Procedure Consultation

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.

P443 Report Phase Consultation

This Modification seeks to limit the exposure of all GB parties, including consumers, to extreme prices because of tight margins across the European energy markets. The proposed solution is to cap the price that enters the BSC Imbalance Price calculation at the Value of Lost Load (VoLL – currently £6,000/MWh), for Interconnector actions only. VoLL under the BSC represents the value to customers of unsupplied energy. National Grid Electricity System Operator (NGESO) would still be able to take Interconnector actions it deems necessary, but these would be capped in the Imbalance Price calculation where the relevant actions exceed VoLL.

This Modification will require a period of mandatory Change of Measurement Class (CoMC) activity for all Non-Half Hourly (NHH) Unmetered Supplies (UMS) Metering Systems running from October 2023 to October 2024. It will also require all new UMS connections to be settled Half Hourly (HH) from October 2023.

If the transition for NHH UMS Metering Systems is not brought forward, combined with the workload from other MHHS activities, It will significantly increase the risk that there will be insufficient time for Customers, Suppliers and UMSOs to address any issues that may arise with the transition to the MHHS Target Operating Model.

View P432 Report Phase Consultation

P432 Report Phase Consultation

This Modification proposes to align the BSC definition of an Advanced Meter with that in the Standard License Conditions (SLC) and to set explicit Half Hourly (HH) Settlement obligations for Current Transformer (CT) Advanced Meters ahead of the migration to Market-wide Half-Hourly Settlement (MHHS). 

Summary

Market-wide Half-Hourly Settlement (MHHS) requires that all Metering System Identifiers (MSIDs) are settled on a Half Hourly (HH) basis and moved to the MHHS Target Operating Model. The Code Change and Development Group (CCDG) has recommended moving Current Transformer (CT) Advanced Meters to settle HH by October 2023 in its consultation on the Transition Approach for MHHS. If this recommendation is not implemented the risk is that there will be insufficient time for Customers, Suppliers and their Agents to address issues that may arise will be increased, especially against the backdrop of the larger MHHS migration activities that will be needed for smart Meters.

  • Inconsistent definitions of Advanced meter in the BSC versus Electricity Supply Standard Licence Conditions; and
  • The risk of not meeting MHHS Transition Timetable leading to Settlement errors.

P432 seeks to align the BSC definition of an Advanced Meter with that in the SLC and to set explicit HH Settlement obligations for CT Advanced Meters ahead of the migration to MHHS. Existing CT Advanced Meters settling NHH are expected to migrate using the Change of Measurement Class (CoMC) process to settle HH by October 2023 and all new connections for CT Advanced Meters will be expected to settle HH from October 2022. Any opt-out/in rights for customers under the SLC are reflected in the P432 solution.
