At the time of writing, this would need to complete by October 2024. It will also require all new UMS connections to be settled Half Hourly (HH) from 12 months prior to M11, currently October 2023.

Read More

CP1563 ‘Altering the Trigger Point and subsequent Timescales for Commissioning SVA CT Operated Metering Systems and issue of Data Flow’

CP1563 seeks to update some of the trigger points for Current Transformer (CT) Commissioning and subsequent sending of data flows as the Proposer considers that they are not appropriate for CT operated metering systems of all types.

Read More

CP1567 ‘New BSC Procedure (BSCP) for Assurance Information Requests (AIRs)’

The AIR is a Performance Assurance Technique (PAT) which was introduced in May 2022. Currently there is no related BSCP for an AIR, therefore when issuing an AIR, there is no written obligation on Parties to adhere to the request.

Read More

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.

Read More

CP1568 ‘Inclusion of new LDSO-mastered SMRS data items’

This Change Proposal will include new LDSO-mastered SMRS data items in the SVA Data Catalogue, the REC EMAR Data Specification and BSCP604. 

Read More

CP1572 ‘Specifying the requirements to provide SLDs for HV and EHV sites’

Currently there is no requirement in the BSC to produce SLDs despite a number of BSC processes requiring one to be submitted. Without the requirement to produce SLDs being specified, some Parties have not felt incentivised to create them.

CP1558 ‘New Registration data items to facilitate MHHS’

This Change Proposal will introduce new Registration Service data items and supporting BSC processes into existing Supplier Meter Registration Service (SMRS) systems. 

Read More

P441 ‘Creation of Complex Site Classes’

This Modification looks to progress a recommendation of the Issue 88 Workgroup to introduce Complex Site classes. These classes would categorise the types of Complex Site, each having clearly defined criteria within the BSC. A new “type” of Complex Site (referred to as a Class 6 Complex Site) to allow approval of ”non-standard” complex sites would also be introduced.
P441 would also clarify when the netting of Imports from Exports for multiple Metering Systems registered in Supplier Volume Allocation (SVA) is permitted.

This change would facilitate consistency across the market and as so called “Local Energy Schemes” become more popular, rules for when netting are permitted would be clearly defined going forward.

CP1585 ‘Submission of Half Hourly data for Embedded LDSO sites to Host LDSO’

This CP proposes that the Half Hourly Data Collector send Half Hourly data for Embedded LDSO connected sites to the Host LDSO via D0275 and/or D0036 to improve the quality of forecasting and reduce manual effort. 

Read More

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.

Read More

CP1574 ‘Improving the use of the D0215 data flow in the relevant industry processes’

This CP seeks to implement the recommendation from the Issue 99 Workgroup, which involves updating Balancing and Settlement Code Procedure (BSCP) 515 ‘Licensed Distribution’ and the Retail Energy Code (REC) Meter Operator Schedule 14 documents to streamline the use of the D0215 flow in its associated processes.

Read More

P460 aims to change responsibility for proposing, consulting on and obtaining approval of the Market-wide Half Hourly Settlement (MHHS) Migration Plan from BSCCo to the Market-wide Half Hourly Settlement Programme (MHHSP).

Read More

P453 ‘Metering Dispensation process improvements and clarification to the CoPs’

This Modification seeks to progress two recommendations from Issue 93 ‘Review of the BSC metering Codes of Practice’. The first recommendation clarifies the relevant Code of Practice (CoP) for circuits embedded behind the Boundary Point Metering System or Defined Metering Point (DMP). The second recommendation eliminates the need for Metering Dispensations when the Actual Metering Point (AMP) does not coincide with the DMP, but there is no impact on Settlement accuracy.

Read More

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). 

Read More

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.

Read More

CP1587 ‘Obsolete Metering Equipment’

Providing a process and transition period to remove unsupported assets and mitigate the risk to Settlement. 

Read More

P466 ‘BSC Section N Modernisation’

This Modification seeks to update BSC Section N ‘Clearing Invoicing and Payment’ to support the effective running of the Funds Administration Agent (FAA). The Modification will align the BSC with Elexon’s updated financial systems and modern banking practices to increase the efficiency of service provided to industry.

Read More

P454 ‘Removal of BSC obligations to provide BMRS Data via TIBCO and the High Grade Service’

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.

P454 is a recommendation from BSC Issue 95, which considered the impacts associated with maintaining the legacy TIBCO service.

Read More

P455 ‘On-Site Aggregation as a method to facilitate Third Party Access’

This Modification seeks to establish a more cost effective and efficient method for delivering Third Party Access on private networks that include domestic and small business customers. It does so by enabling aggregated meter data from sub meters on private networks to be submitted into Settlement in lieu of data from Settlement meters installed at the Boundary Point.

Read More

P463 ‘Introduce a Standard Change Process’

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.
