This page shows which Modifications and Change Proposals have been identified as impacting a Supplier. 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.
P496 Defining DIP Manager Data and how it can be shared
This Modification will clarify in the DIP Rules that due to the transactional nature of data in Common Blocks, this data shall be defined as DIP Manager Data for service management and issue resolution. Establish a mechanism for sharing DIP Manager Data, including from Messages’ Common Blocks, with relevant stakeholders like Code Bodies, ensuring a clear legal basis for sharing personal information, such as MPAN data, when necessary.
P472 Amendment to provisions for Parties to bring claims against BSC Agents in BSC Section E
P459 Allowing different Supplier Agents to be appointed to Import and Export MSIDs
This Modification would allow Suppliers to appoint different Supplier Volume Allocation (SVA), Meter Operator Agents (MOAs) and Data Collectors (DCs) for the Import and Export Metering System Identifiers (MSIDs) where Data Communications Company (DCC) adopted smart meters are installed. Being able to appoint different Supplier Agents across Import/Export MSIDs will remove a barrier preventing the use of Export MSIDs for small-scale micro-generation, which currently disbenefits Suppliers, sales and operators of micro-generation, and electricity consumers.
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.
P476 Exemption from MHHS Requirements for SMS Supplier Qualification
P476 sought 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.
P477 Data Protection Provisions for Market-wide Half Hourly Settlement
The purpose of this Modification is to address the need for personal information sharing in the Balancing and Settlement Code (BSC), once the Market-wide Half Hourly Settlement (MHHS) arrangements are operational.
P442 Reporting chargeable volumes for exempt and licensed supply
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 Notification Agent”.
CP1601 Add ‘ZD Authorisation Level’ for receiving Settlement performance data to the BSCP38
The Customer Assurance Report Platform (CARP) is launching in April 2025, which will enable Suppliers to directly access Settlement performance data metrics. It is critical that only authorised persons are granted access to the data for information and security purposes. Currently, there is no agreed method for registering and authorising access to CARP. The BSC already has an authorisation process, defined in BSCP 38: ‘Authorisations’, but it does not include an authorisation level for CARP.
CP1599 Remove the requirement in BSCP602 to specify the Half Hourly Data Aggregator in Non-Final Demand Declarations
CP1599 proposes updates to BSCP602 to remove the requirement for Non-Final Demand Declarations to specify the HHDA and Effective From Date (EFD) for each MSID. It also adds a process in the Customer Solution to check if an MSID in the SVA Metering System and Asset Metering System Register has transitioned to the MHHS arrangements and validate and store the relevant MSID information.
