BSC Changes impacting a Supplier
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.
P472 ‘Amendment to provisions for Parties to bring claims against BSC Agents in BSC Section E’
This Modification proposes to amend BSC Section E to remove the requirement for Parties to be able to bring claims against BSC Agents. An industry Workgroup will be formed to consider what other measures (if any) might be appropriate to mitigate the impact of this on Parties.
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).
P471 ‘Amendment to BSC Section E to allow more flexibility in procurement of BSC Agents’
To allow more flexibility in the requirements for procurement of BSC Agents, to allow the option of having these systems operated by the service provider who developed them (at least for the duration of the transition period), while the currently-appointed Supplier Volume Allocation Agent (SVAA) continues to operate legacy processes.

CP1595 ‘Correcting the D0148 flow in BSCP520 – CP1590 fix’
CP1595 will remove D0148 from 3.1.12 in BSCP520: Unmetered Supplies Registered in SMRS. The change will ensure references to the Data Transfer Network flows (D0148 in this case) is inputted for its correct use.
P412 ‘Ensuring non-BM Balancing Services providers pay for non-delivery imbalances at a price that reflects the real-time value of energy’
This Modification will introduce imbalance charges for non-Balancing Mechanism (BM) Balancing Services providers, where their delivery does not match instructed volumes. This will mean the GB market more effectively meets the requirements of the Clean Energy Package.
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.
CP1594 ‘Creating an Approval Process for New and Legacy Communication Types’
Older metering communication types are quickly becoming redundant and are being replaced by newer communication types. Elexon are proposing to create an approvals process to allow for the managed end dating of older technologies, such as Public Switched Telephone Network (PSTN), Circuit Switched Data (CSD) and subsequently 2G.
P470 ‘Protecting the Imbalance Price from IOLC related distortions’
P470 seeks to reprice Offer prices in the Imbalance Settlement Price calculation where those Offers were impacted by price restrictions introduced by the Inflexible Offers Licence Condition (IOLC).
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.
P451 ‘Updating BSC Black Start provisions and compensation arrangements’
P451 seeks to facilitate the implementation of NGESO’s new approach to Black Start, termed System Restoration. In doing so, it proposes to update all BSC references to “Black Start” to “System Restoration”, and enable contracted Restoration Service Providers who are non-BSC parties to claim BSC Black Start compensation.
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.

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.
P469 ‘Credit Default Refusal and Rejection Period’
P469 proposal seeks to delay the Credit Default Refusal and Rejection Periods. This change would give parties a two-hour window from the Level 2 Credit Default notification until the time when any Energy Contract Volume Notifications (ECVN) related to a defaulting party are rejected.
To implement the proposed Solution, this Modification aims to change BSC Section M, 3.3.3 a (i) and (ii).
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.
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.
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”.
CP1590 ‘Enabling use of DTN agent appointments process for P434’
Enabling suppliers who may be considering the use of DTN derived Dataflows to meet the requirements to migrate their Unmetered Supply (UMS) portfolios over the 12 months up to the UMS mandate go live date.
CP1587 ‘Obsolete Metering Equipment’
Providing a process and transition period to remove unsupported assets and mitigate the risk to Settlement.
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.
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).
