P431 Report Phase Consultation13 December 2021
Modification P399 implemented to support greater competition for balancing services8 November 2021
Webinar on P375: Settlement of Secondary BM Units held on 7 December 202121 October 2021
P433 ‘P375-P420 Legal Text Alignment’
P433 seeks to ensure that the Legal Text for Approved Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’ is aligned with the BSC baseline introduced by the implementation of P420 ‘Retail Code Consolidation Significant Code Review’. This Modification will correct a number of manifest errors introduced into the P375 legal text by P420 and will therefore allow the implementation of the P375 Legal Text in the BSC on the P375 Implementation Date.
P432 ‘Half Hourly Settlement for CT Advanced Metering Systems’
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).
P431 ‘Post Brexit Agreement Updates’
As a result of the UK leaving the EU, Great Britain (GB) is no longer part of the Internal Energy Market and updates are required to the BSC to ensure that the legal text appropriately reflects these changes.
P430 ‘Extension of P375 to include Suppliers’
P430 seeks to extend the solution to Approved Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’ to allow Suppliers to register Asset Meters and allocate Asset Metering System Identifier (AMSID) Pairs to Secondary Balancing Mechanism Units (SBMUs).
P429 ‘Switching off Participant-Reported PARMS Serials’
P429 would permanently cease the operation of, and remove the obligations associated with, participant-reported Performance Assurance Reporting and Monitoring System (PARMS) Serials and associated Supplier Charges.
P428 ‘Correction to P376 Legal Text’
This Modification is required to correct an error contained within the approved legal drafting for P376. This Proposal will ensure that Virtual Lead Parties (VLPs) do not need to submit the status of Metering System Identifier (MSID) pairs contained within secondary Balancing Mechanism (BM) Units that do not use the baselining methodology introduced in the P376 solution.
P427: Publication of Performance Assurance Parties’ impact on Settlement Risk
This Modification seeks to amend BSC Section Z to allow the Performance Assurance Board (PAB) to recommend that the Panel publish notices to industry in respect of Performance Assurance Parties’ (PAPs’) contribution to Settlement Risk along with relevant risk data.
P426 ‘Combining related BSC Parties’ Energy Indebtedness positions for the Credit Cover Percentage calculation’
This Modification proposes to remove inefficiencies with the Credit Cover calculation by allowing related BSC Parties to combine their Energy Indebtedness prior to calculating the Credit Cover Percentage.
P425 ‘Single Supplier Shared SVA Meter Arrangements’
This Modification aims to reduce the requirement from two or more Suppliers, to one or more Suppliers, to be involved in a Shared Supplier Volume Allocation (SVA) Metering Arrangement.
