From today anybody regardless of whether they work in the electricity sector or not can get access to the same level of data that is used for most of Elexon’s reporting on electricity Settlement.

We have published updated versions of the 2022/23 Risk Evaluation Register (RER) and the Risk Operating Plan (ROP) following a review completed in July 2022.

From today voting is open for the 2022 BSC Panel elections. You can vote until close of play on 26 August. Below are the six candidates that could be elected (or re-elected) to serve on the Panel.

A new ‘Code of Practice (CoP11) for the Metering of Balancing Services Assets for Settlement Purposes’ has been introduced, defining the minimum BSC requirements for Asset Metering Systems.

Elexon has recently obtained feedback from Suppliers that the current Settlement monitoring approach may act as a disincentive for Suppliers to move sites to elective Half Hourly (HH) Settlement in preparation for Market-wide Half Hourly Settlement (MHHS). This is because moving ‘good’ performing sites to HH Settlement may reduce the performance of their remaining Non Half Hourly portfolio.

We issue two Circulars during each Market Domain Data (MDD) Release. These are: Impact Assessment Circulars that informs you of the proposed changes to be included in the next Version of MDD; and a Final Circular that confirms the changes being committed to the next Version of MDD.

We are looking to engage with interested parties through our Settlement and Invoicing Solution User Group. Participating in the User Group will enable you to help shape the future design of the solution on our new digital platform, Elexon Kinnect.

We have been working on changes to the Elexon Kinnect Customer Solution which delivers functional enhancements to the contacts, authorised signatories, addresses and bank details elements of the Elexon Kinnect Customer Solution. These changes are usable from 20 June 2022 and provide benefits for existing customers and new market entrants.

Following the Grid Supply Point (GSP) Group Metering Issues identified in GSP Groups _C and _J, Elexon has looked at further impacts the corrected data could have on Settlement processes.

After completing some additional analysis, we identified that there were some impacts on Transmission Loss Factors (TLFs).  These impacts were small, mostly affecting the Summer 2022 period.

We have been developing an exciting new data and insights platform, the Elexon Kinnect Insights Solution, which builds on our existing Balancing Mechanism Reporting Service (BMRS) to offer a richer and more detailed data service for GB electricity.

The Credit Assessment Load Factor (CALF) values for the Autumn 2022 BSC Season, which runs from 1 September 2022 to 30 November 2022, are available from the Credit/Credit Alerting section under the Financial and Credit menu on the Elexon Portal.

If you are the Lead Party of a non-Credit Qualifying Balancing Mechanism Unit (BMU), you can appeal an assigned CALF value if you believe it does not accurately represent your expected activity by Monday 1 August 2022.

At its May 2022 meeting, the Performance Assurance Board (PAB) undertook a review of its approach to managing the Settlement Performance standard. The PAB has approved two changes to the Settlement Performance Standard.

The Technical Assurance Scope contains the checks we will perform during the period. A ‘within period revision’ to the scope can also be made with approval from the PAB. The check will then take place anytime during that BSC year.

Elexon is helping the industry to get set for the go-live of the Central Switching Service (CSS) this summer as part of Ofgem’s Switching Programme.

The CSS, which will be governed by version 3.0 of the Retail Energy Code (REC), will provide a single, dual fuel switching process for gas and electricity. The aim is to make switching faster and more reliable.

On 12 May, we issued BSC Circular EL03581, which gave notice to BSC Parties that the ‘Coronavirus Disapplication Period’ for Supplier Charges will be ending. This means that, from September 2022, Supplier Charges for SP08 will be reapplied from the September Performance Assurance Reporting and Monitoring System (PARMS) Reporting Period.

In the past eight years, we have identified five Grid Supply Point (GSP) Metering errors, equal to around 1.4% of the total number of GSP Meters. These errors have caused energy to be recorded incorrectly. As any unaccounted energy is allocated to BSC Parties through GSP Group Correction and Transmission Losses, such metering errors can present a large impact on the allocation of energy and therefore the accuracy of Trading Charges to BSC Parties.

We are publishing a beta version of our GSP change-point detection model to gather feedback from participants and help us identify other areas where central analytics and reporting could support industry in mitigating risks to Settlement.

Elexon has been investigating errors in Settlement related to two Grid Supply Point (GSP) Groups: South Eastern GSP Group (Group _J); and London GSP Group (Group _C). This follows our continued monitoring of the Annual Demand Ratio (ADR).

We are delighted that today, 9 May, Ofgem confirmed its decision to appoint Elexon as the independent Capacity Market Advisory Group (CMAG) secretariat, subject to a BSC Modification being raised and approved to enable us to do the work.

Elexon will be joining forces with industry not-for-profit Icebreaker One as part of their government-supported Open Energy programme, which seeks to revolutionise the way data is shared across the energy sector to make sure the UK achieves its Net Zero goals. 

On 30 June 2022, Elexon will implement Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point‘.  This is a major change to the Wholesale Electricity Trading Arrangements, which supports Net Zero by creating more opportunities for smaller asset owners to provide balancing services.  

We issue two Circulars during each Market Domain Data (MDD) Release. These are: Impact Assessment Circulars that informs you of the proposed changes to be included in the next Version of MDD; and a Final Circular that confirms the changes being committed to the next Version of MDD.

After every Technical Assurance audit we produce a non-confidential findings report that is presented to the Performance Assurance Board (PAB).

Centrica is due to begin a trial this September where controllable storage heaters will provide demand-side response (DSR) when needed, by dialling down their demand. 

It is the second trial which has been approved by Ofgem to use Elexon’s Balancing and Settlement Code (BSC) Sandbox. The Sandbox allows innovators to trial concepts in a live market environment without having to meet all the usual BSC rules.

Yesterday (21 April) Ofgem confirmed that the Balancing and Settlement Code will be used to govern and fund the new Data Integration Platform (DIP) to support Market-wide Half Hourly Settlement (MHHS). This means that Elexon will manage the DIP service provider, which is currently being procured through the MHHS Programme.

Today the Department for Energy Department for Business, Energy and Industrial Strategy (BEIS) and Ofgem jointly responded to the consultations they published in July 2021 on a Future System Operator (FSO), and reforming the energy codes.  National Grid ESO will move away from National Grid plc and become an independent, publicly owned FSO.

As part of that process there will also be a consultation on the ownership of Elexon, which is currently owned by National Grid ESO. 

We issue two Circulars during each Market Domain Data (MDD) Release. These are: Impact Assessment Circulars that informs you of the proposed changes to be included in the next Version of MDD; and a Final Circular that confirms the changes being committed to the next Version of MDD.

This article, written by Lawrence Jones, Head of Rules Management at Elexon, talks about a new site we have built so that the BSC and related documents are available digitally. This helps companies and other people to browse the documents using  improved navigation, web pages instead of PDFs, and a site search. 

Elexon has been working on an exciting project to develop a brand new site that will enable you to have much easier access to the Balancing and Settlement Code (BSC) and its subsidiary documents, ‘the Digital Code’.

The clock change this weekend will result in a ‘short’ day which will impact Settlement periods and contract notifications. On a ‘short’ clock change day, there are only 46 Settlement Periods instead of the normal 48.

Elexon is investigating potential errors in Settlement related to the South Eastern GSP (Grid Supply Point) Group (Group _J) and the London GSP Group (Group _C). This follows our continued monitoring of the Annual Demand Ratio (ADR).

National Grid ESO has resubmitted Balancing Services Adjustment Actions (BSAA) and Balancing Services Adjustment Data (BSAD) files for multiple settlement dates throughout 2021. The period covers January through to November 2021 and is across 69 distinctly impacted Settlement Periods.

We issue two Circulars during each Market Domain Data (MDD) Release. These are: Impact Assessment Circulars that informs you of the proposed changes to be included in the next Version of MDD; and a Final Circular that confirms the changes being committed to the next Version of MDD.

Elexon has been monitoring the on-going impacts of component shortages and supply chain challenges which are impacting on the availability of electricity Meters and related equipment. To help us understand the extent of these challenges, we have created a short survey to assess the impact on the industry.

The Credit Assessment Load Factor (CALF) values for the Summer 2022 BSC Season, which runs from 1 June 2022 to 31 August 2022, are available from the Credit/Credit Alerting section under the Financial and Credit menu on the Elexon Portal.

If you are the Lead Party of a non-Credit Qualifying BMU, you can appeal an assigned CALF value if you believe it does not accurately represent your expected activity.

We have been making changes to the layout and content on Newscast, which is our weekly newsletter that features key information about the industry and BSC activities.

To deliver on our commitment to providing enhanced, customisable data we are migrating the aging Balancing Mechanism Reporting Service platform (BMRS) to the Elexon Kinnect Insights Solution. Through easier access to data and data insights, the new Insights Solution will play a key role in supporting existing  companies, new entrants and innovators who want to develop new products and services.

This page aims to answer common questions about participation in the testing of system changes related to Modification P375, part of the June 2022 Release.
