List of all BSC Modifications
These pages list all Modifications issued since 2001. Modifications are raised to introduce changes that would alter any part of the BSC or any Code Subsidiary Documents (CSDs) or BSC Systems impacted by the proposed changes.
P475 Allowing All Storage Sites to set and fix their own Production/Consumption Flags
The purpose of this Modification is to address the issue of storage BM Units flipping between Production (P) and Consumption (C) statuses. This flipping leads to significant financial challenges for parties managing large storage units. The proposal seeks to allow storage BM Units to fix their P/C status, thereby mitigating these challenges.
P474 Governance, funding and operation of the DIP
This Modification proposes changes to the BSC to enable the ongoing governance, funding and operation of the Data Integration Platform (DIP).
P473 Correcting inconsistencies in the P415 Legal Text
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.
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.
Elexon will hold a webinar on Thursday 27th June to discuss P471 and P472. If you are interested, please sign up via this form
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).
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).
P468 Enabling Elexon to support the (currently in draft) Electricity Support Payments and Levy Regulations 2024
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).
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.
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.
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).
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.
P462 The removal of subsidies from Bid Prices in the Balancing Mechanism
This Modification aims to reduce consumer cost potentially caused by the interaction between the BM and support mechanism arrangements. This shall be done by removing distortion of support mechanisms (such as Contracts for Difference (CfDs) and the Renewables Obligation (RO) schemes) to reduce actions being taken outside of consumer cost order when following the Bid stack merit order.
The proposed solution for consideration by an industry Workgroup is to modify the equation BSC Section T ‘Settlement and Trading Charges’ paragraph 3.11 to pay the lost support mechanism.
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.
P460 Amend the responsibility to propose and consult on a MHHS Migration Plan
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).
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.
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.
P457 Replace the Electricity Arbitration Association with the London Court of International Arbitration
P457 proposes to remove the Electricity Arbitration Association (EAA) from the BSC and replace with the London Court of International Arbitration (LCIA) to deliver better value for money and service.
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.
