List of all BSC Modifications

This Modification would remove the existing requirement within BSC Section V ‘Reporting’ for the Balancing Mechanism Reporting Agent (BMRA) to provide BMR Service (BMRS) data via the legacy High Grade Service, otherwise referred to as the TIBCO service. 

This Modification seeks to allow correct reporting of chargeable volumes to the EMRS company for SVA Metering Systems that record both exempt supply and licensed supply through the addition of a new third party role, the “Exempt Supply Calculation Agent”.

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. 

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 proposes has no impact on the operation of the BSC – they are, essentially, administrative changes only. 

This Modification would cease the operation of, and remove the obligations associated with,
participant-reported Performance Assurance Reporting and Monitoring System (PARMS)
Serials and associated Supplier Charges.

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.

this is the page teaser that will appear on the page, on the listing page and on the BSC homepage under the modification section – more stuff here 21/09/2022 – and again later one that same day

This Modification seeks to enable BSC Systems to aggregate the Import data of all non-Final Demand sites for exclusion from Balancing Services and Use of System (BSUoS) charges.

P418 aims to ensure the Legal Text for approved BSC Modification P383 properly reflects the approved solution, business requirements, and is aligned with the BSC baseline introduced by P344, P354 and P388. In particular, it will clarify that the solution being delivered by P383 is applicable to both Supplier Base Balancing Mechanism (BM) Units and Additional BM Units.

[page teaser field]This Modification seeks to remove the Letter of Credit templates and Approved Insurance Product requirements from annexes M1 – M4 of the BSC. The Modification also seeks to place a requirement on Elexon to publish the Letter of Credit templates and Approved Insurance Product requirements on the BSC Website.

P402 will introduce new reporting requirements on Licensed Distribution System Operators (LDSOs) and Elexon that will ensure the provision of data to enable the (National Electricity Transmission System Operator) NETSO to set Transmission Network Use of System (TNUoS) demand residual tariffs and enable accurate billing of subsequent charges.

Following the conclusion of its Targeted Charging Review Significant Code Review , Ofgem directed National Grid and certain  LDSOs to make changes to how residual revenues are recovered through Distribution Use of System (DUoS) and TNUoS demand charges.
