List of all BSC Modifications

This Modification seeks to enable BSC Systems to aggregate the Import data of all non-Final Demand sites for exclusion from Balancing Services and Use of System (BSUoS) charges.

P418 aims to ensure the Legal Text for approved BSC Modification P383 properly reflects the approved solution, business requirements, and is aligned with the BSC baseline introduced by P344, P354 and P388. In particular, it will clarify that the solution being delivered by P383 is applicable to both Supplier Base Balancing Mechanism (BM) Units and Additional BM Units.

P416 seeks to amend the BSC to include an appeals mechanism that BSC Parties could use to challenge items in the Annual Budget.

P411 aims to improve the effectiveness of the Qualification Performance Assurance Technique (PAT) by requiring new Licensed Distribution System Operators (LDSOs) to undergo Qualification in this role. 

P410  will introduce changes to the imbalance price calculations to ensure BSC compliance with the European Imbalance Settlement Harmonisation regulations.

P408 is being raised as a consequential BSC Modification to Grid Code Modification GC0130.

The Modification aims to deliver:

• Continued alignment of the Grid Code and BSC processes; and
• Improved market transparency and efficiency through provision of additional Output Usable, Margin and Surplus data in the two to three year ahead timescale.

P405 will allow notices that the BSC currently requires to be sent by post or fax to be sent by email.

Moving the Self Assessment Document and associated documents from BSCP537 and making them a Category 3 BSC Configurable Item

Enabling reform of residual network charging as directed by the Targeted Charging Review

To clarify the governance arrangements for BSC Panel Alternates in respect of their contribution to quoracy and voting at BSC Panel meetings. This will help to address ambiguity within the existing arrangements.

BSC Panel Modification Business via Video/Teleconference

P399 seeks to include additional information in the Balancing Services Adjustment Data (BSAD) to identify the assets involved in bilateral trades.

P398 seeks to increase accessibility to data held by Elexon and BSC Agents. It will better align the BSC with the United Kingdom’s Industrial Strategy.

P397 seeks to introduce a mechanism through which the Balancing and Settlement Code Company (BSCCo) determines whether certain Parties should carry out the Settlement Adjustment Processes following a DCE.

Revised treatment of BSC Charges for Lead Parties of Interconnector BM Units

Aligning BSC Reporting with EMR Regulations - an enduring solution

Removal of Unused BSC Provisions

Disapplication of Supplier Charge SP01

This Modification will ensure the process and responsibilities for amending BSC provisions constituting EBGL Article 18 terms and conditions reflect delegations made by NGESO in favor of the BSCCo and BSC Panel, to ensure a unified market change process.

Introducing Desktop Audits

P390 seeks to introduce a framework into the BSC that allows the Elexon Board to determine whether Elexon can undertake additional activities provided certain conditions are met, and with the consent of the Authority.

P389 will delete BSC Section K paragraph 3.1.8(b) in order to remove conflict between the BSC and Capacity Market rules

'Aligning the P344 and P354 Solutions'

This Modification Proposal aims to amend the Balancing and Settlement Code (BSC) Panel Elections process to allow communications between parties via email. Other communication methods could be approved by the BSC Panel on a case-by-case basis.

Corrections and clarifications to the P344 ‘Project TERRE’ legal text

Improving the efficacy and efficiency of the Section H Default provisions

P384 'The publication of European Electricity Balancing Guideline (EB GL) balancing data by BMRS'

Enhanced reporting of demand data to the NETSO to facilitate CUSC Modifications CMP280 and CMP281

The Balancing and Settlement Code (BSC) contains multiple references to European Union (EU) legislation and bodies. Additionally, it also contains text introduced as a result of implementing various EU legislation. Retaining these references and text following the United Kingdom’s (UK’s) withdrawal from the EU without a deal (‘no-deal Brexit’) would have meant that the BSC would have been technically inaccurate but would have remained operable because of the European Union Withdrawal Act 2018.

P381 proposes to remove Section C3.9.1 of the BSC in respect of ‘quarterly reports’. 

Modifying the P344 wording of BSC Section Q ‘Balancing Services Activities’ to ensure National Grid ESO’s continued compliance with the Balancing and Settlement Code (BSC) and the Replacement Reserve Implementation Framework (RRIF).

P369 proposes to modify the Balancing Settlement Code (BSC) to reflect the creation of a new National Grid Electricity System Operator (NGESO) that is legally separate from National Grid Electricity Transmission Limited (NGET).

P368 seeks to amend provisions in the timing and revision of the PAF Procedure documents in order to support the objectives of the Performance Assurance Framework (PAF) Review in delivering a more efficient and effective PAF.

P367 proposes to remove the Supplemental Balancing Reserve (SBR) and Demand Side Balancing Reserve (DSBR) arrangements from the Balancing and Settlement Code (BSC). 

P366 proposed amending how Supplier Charge SP08a is applied to Non Half Hourly non-Domestic Meters that are hard-to-read (HTR). It is believed that applying Supplier Charge SP08a to HTR Metering Systems is anti-competitive and limits consumer choice. 

Enabling Elexon to tender for the Retail Energy Code (REC)

P364 will clarify the requirements for configuring and registering Plant and Apparatus in Balancing Mechanism (BM) Units. Specifically where Parties seek to share responsibility for Imports and Export from the same Plant and Apparatus or via the same Boundary Point. It will also clarify the circumstances and requirements for maintaining BM Unit registration details and seeking to re-register BM Units when the configuration of Plant and Apparatus change.
