This page shows which Modifications and Change Proposals have been identified as having no impact on BSC Parties or Party Agents. Please note that the assessment of where impacts may affect certain roles within the electricity market may be amended during the course of the Change process.
CP1617 Correcting the timing of NHHDC deemed reads in BSCP708
This Change Proposal addresses an error in BSCP708 that incorrectly requires Non-Half Hourly Data Collector or NHHDCs to generate deemed final reads for their Effective To Date (ETD). The change will align BSCP708 with BSCP504 by requiring deemed reads to be generated for the Migration Date instead, ensuring accurate Settlement data.
P483 Enabling Asset Metering for Non-Half Hourly Boundary Metering Systems
The implementation of BSC Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’ allows Asset Metering System Identifier (AMSID) Pairs to participate in Settlement by utilising metering situated behind the Boundary Point. However, it requires that the associated MSID Pair—the Boundary Point Metering System—must be settled Half-Hourly. This requirement prevents most domestic consumers from participating in flexibility services with smart devices, as the majority are not half-hourly settled, and consumers, along with their Virtual Lead Parties (VLPs), cannot mandate changes to the meter’s Measurement Class.
P480 Publication of regional demand forecast data to fulfil ESRS Reporting requirements
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.
CP1596 Amend BSCP40 to include the process for changes to the Retail Energy Code Energy Market Data Specification
This CP seeks to update BSCP40 to define processes for changing EMDS items.
P458 Introducing Data Controller and Processor Obligations in the BSC for MHHS Testing
The purpose of this Modification is to address the need for personal information sharing in the Balancing and Settlement Code (BSC), specifically in the context of the Market-wide Half Hourly Settlement (MHHS) testing. The current BSC General Data Protection Regulation (GDPR) and data protection provisions were not designed to allow the sharing of personal information, which has now become necessary for the planned MHHS testing.
P468 Enabling Elexon to support the (currently in draft) Electricity Support Payments and Levy Regulations 2024
P473 Correcting inconsistencies in the P415 Legal Text
Elexon received feedback from industry on the P415 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. This revealed that the P415 Legal Text does not correctly describe the intended solution for P415 as well as some inconsistencies and omissions.
P481 Enable Elexon to be the Market Facilitator Delivery Body
This Modification seeks to extend Elexon’s vires to take up the role of Market Facilitator Delivery Body, to implement Ofgem’s decision published on 29 July 2024.
CP1592 Upgrade of NHHDA and EAC/AA systems from Oracle 12c to version 19.21
Upgrade NHHDA and EAC/AA systems to the latest available version of Oracle 19.21.
P461 Accurate Reporting of Customers Delivered Volumes to Suppliers
The details reported to Suppliers when a customer delivers a Bid Offer Acceptance (BOA) through a Virtual Lead Party (VLP) do not reflect any adjustments made to that data in Settlement. This Modification proposes to address this issue by amending the values reported to Suppliers.
P467 Enduring Solution in an event of a Gas Deficit Emergency (GDE)
This is a follow on Modification from Issue 105 and provides an enduring solution in an event of a Gas Deficit Emergency (GDE).
CP1591 New Site Visit Check Code Valid Set value
The implementation of Distribution Connection and Use of System Agreement (DCUSA) Modification DCP411 ‘Charging De-energised sites’ involves updating the J0024 data set by adding a new Enumeration Value.
CP1593 New Interconnector Fuel Type Category: Greenlink
Changes are needed to the Insights Solution to ensure data relating to the new Greenlink Interconnector is provided to market participants alongside existing data relating to Settlement arrangements in the Great Britain (GB) electricity market.
CP1582 Update BSCP520 on Change of Measurement Class to ensure the UMSO send a D0388 with a zero charge code
CP1582 was originally raised as a housekeeping Change Proposal (CP) to update BSCP520 ‘Unmetered Supplies Registered in SMRS’ step 3.6.2.3, as introduced erroneously by P434 ‘Half Hourly Settlement for UMS Metering Systems’], states “UMSO confirms the de-energisation date to Supplier, NHHDC and MA”’ as Non Half Hourly (NHH) Unmetered Supply (UMS) sites don’t have a Meter Administrator (MA).
Following an objection to the CP as housekeeping, and subsequent consultation period, CP1582 has been expanded to provide greater clarity and alignment with industry process for BSCP520 where a Change of Measurement Class (CoMC) event has occurred.
CP1584 Allow non-BSC Parties to raise Change Proposals, add a CP withdrawal process and remove BCA/PACA concept
BSC Issue 102 ‘BSC Change Process Review’ identified several improvements to align and simplify BSC Change processes on solution ownership and recommended Elexon make changes to several current processes described within BSC Procedure (BSCP) BSCP40 “Change Management”.
CP1586 Defining the requirements for Minimum Burden and CT ratios
In some cases, the Current Transformer (CT) ratios for the maximum current of the circuit is not appropriately selected, even though these ratios are vital for accurate energy settlement as they ensure safe and precise current conversion, maintain metering equipment within its optimal operating range, and uphold regulatory compliance standards. CP1586 originates from Issue 93 ‘Review of the BSC Metering Codes of Practice’.
P464 Housekeeping and updating BSC references to “Consumer Scotland”, “Generation Curtailment Validation Committee” and “GCVC”
This housekeeping Modification replaces references to “Citizens Advice Scotland” with “Consumer Scotland”. It also replaces any references to “Network Gas Supply Emergency Settlement Validation Committee” and “NGSESVC” to “Generation Curtailment Validation Committee” and “GCVC”. Additionally, it also corrects 5 non-material errors and inconsistencies across 5 Sections of the Balancing and Settlement Code (BSC).
CP1578 Enabling Embedded LDSOs to submit Site Specific LLFs
This CP proposes updates to remove issues that may stop Embedded LDSOs from submitting Site Specific LLFs. These updates will define the process for submitting Site Specific LLFs, including establishing deadlines and requirements for the Embedded and Host LDSOs.
P465 Correction to P415 legal text to amend Credit Cover requirements for Virtual Trading Parties
This Modification is required to correct an error in the approved legal drafting for P415. This Proposal will ensure that Credit Cover requirements for Virtual Trading Parties (VTPs) correctly take into account the energy volumes (‘Deviation Volumes’) that VTPs trade in wholesale markets, which was the intention of the P415 Workgroup.
P456 Enable Elexon to procure ancillary Technology Services for use by BSC Agents
Removing barriers in BSC Section E that would prevent Elexon updating BSC Agent contracts, therefore enabling BSC Agents to use Technology Services procured by Elexon. This should reduce costs for BSC Parties.
