This page shows which Modifications and Change Proposals have been identified as impacting a Generator. 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
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.
P441 Creation of Complex Site Classes
This Modification looks to progress a recommendation of the Issue 88 Workgroup to introduce Complex Site classes.
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.
P469 Credit Default Refusal and Rejection Period
P469 proposal sought 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).
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.
P479 Amendments to the Credit Cover calculations
This Modification seeks to amend the Credit Cover calculations to make more accurate and operationally efficient estimates of Energy Indebtedness, using data available closer to real time.
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.
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.
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).
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.
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).
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.
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).
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.
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.
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.
CP1587 Obsolete Metering Equipment
Providing a process and transition period to remove unsupported assets and mitigate the risk to Settlement.
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).
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.
