Change Consultations

P480 seeks to facilitate the Electricity System Restoration Standard (ESRS) requirements to publish the day-ahead peak demand forecast for each restoration region and the demand restored in each restoration region published hourly during a System Restoration on BMRS (Elexon’s Insights Solution Platform). P480 is a consequential Modification to GC0156 ‘Facilitating the Implementation of the Electricity System Restoration Standard’.

This Proposed Solution is to make changes to BSC system and BSC Section Q ‘Balancing Mechanism Activities’ and Code Subsidiary Documents to implement these provisions outlined in GC0156. 

The purpose of this implementation consultation is to seek feedback from industry participants on the proposal to bring forward the Implementation Date of P475. By gathering views on the revised timeline, the consultation allows stakeholders to assess and respond to the impact of an earlier delivery of the Modification.

Elexon has identified an opportunity to adjust the timeline, allowing for the earlier delivery of the Modification’s benefits. This feedback will help the BSC Panel make an informed recommendation to the Authority regarding the updated implementation date, ensuring that both market and participant needs are considered.

This is the P444 ‘Compensation for Virtual Lead Party actions in the Balancing Mechanism’ Send Back Consultation, which Elexon is issuing for industry consultation on behalf of the BSC Panel. The purpose of this consultation is to invite BSC Parties and other interested parties to provide their views on the outcomes of the P444 Send Back process. It includes a summary of the additional work undertaken by Elexon and the Workgroup.

This Modification proposes changes to the BSC to enable the Market-Wide Half-Hourly Settlement (MHHS) arrangements.

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 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.

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.

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).

This Modification proposes changes to the BSC to enable the ongoing governance, funding and operation of the Data Integration Platform (DIP).

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
