Performance Assurance Framework: News

The Market-wide Half Hourly Settlement (MHHS) Performance Assurance Framework (PAF) engagement plan supports Elexon’s objectives during the PAF changes due to MHHS. It outlines Elexon’s approach, detailing the audience, purpose, key messages, timing, and engagement methods for key PAF deliverables.

The plan includes key dates for industry stakeholders, related to Settlement Risk resources and changes to Performance Assurance Techniques for the 2025-2026 Performance Assurance Operating Period (PAOP).

The MHHS Programme is introducing changes for legacy Suppliers and agents to support the Migration of Metering System Identifiers (MSIDs) from legacy arrangements to MHHS. Reverse migration can take place during the migration period (from March 2025 onwards) where a customer has switched to a Supplier that is not yet MHHS Qualified.

This is of interest to all Suppliers with Non Half Hourly portfolios

At its meeting on 27 April 2023, the Performance Assurance Board (PAB) approved the deployment of EFR for Settlement Risk 008; the risk that Supplier Volume Allocation (SVA) metered data is not processed or transferred correctly, or is not processed at all.

Due to a global shortage of materials and disruption of global supply chains, there is a shortage of semi-conductors among other crucial components, which impacts the ability for Meter manufacturers to produce and supply electricity Meters, including those required for Settlement under the BSC.

This shortage of Settlement Meters impacts on new connections and fault resolution in both the Supplier Volume Allocation (SVA) and Central Volume Allocation (CVA) markets, and consequently impacts the integrity and accuracy of Settlement.

From 23 February 2023, under Modification P427, Elexon will be able to publish the Settlement performance data of Performance Assurance Parties (PAPs)* under the Peer Comparison Performance Assurance Technique.

Due to a global shortage of materials and the impact of COVID-19 on global supply chains, there is a shortage of semi-conductors among other crucial components, which impacts the ability of Meter manufacturers to produce and supply electricity Meters, including those required for Settlement under the BSC.

This shortage of Settlement Meters impacts on new connections and fault resolution in both the Supplier Volume Allocation (SVA) and Central Volume Allocation (CVA) markets, and consequently impacts the integrity and accuracy of 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.

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.

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.

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.

We are interested in gathering feedback on our Performance Assurance product from parties within the industry to help analyse and identify areas where we could improve. 

From January 2022 a new Error and Failure Resolution approach for Risk 9 will be initiated.

As of 19th July 2021, the government no longer instructs people to work from home. Therefore, with authorisation from our customers we plan to restart on site audits. The Technical Assurance Agent (TAA), currently C&C Group Holdings Ltd, have updated our procedure and practices and these must be followed by all staff when working off site in order to minimise risk to themselves and others.

The three-month notice period required to end the COVID-19 Supplier derogations begins on 1 July. The Performance Assurance Board (PAB) made this decision at its meeting on 24 June 2021, taking into account feedback from industry and the loosening of COVID-19 restrictions.

The PAB believe that there is now a reasonable level of confidence that Government restrictions which significantly impact Settlement operations have concluded. In particular, whilst some restrictions do remain in place, very few business premises are now required to remain closed.

We have published the latest Quarterly Performance Assurance Report for Q4 2020-2021. This report outlines the Key Points of Progress, the Risk Landscape, Key Industry Metrics, Focussed Risk and Event Overview as well as Technique Updates.

The Performance Assurance Board committee agree the approach to monitoring the Supplier Half Hourly (HH) and Non-Half Hourly (NHH) Settlement performance standards and applying Error and Failure Resolution (EFR) on a quarterly basis.

Here are details agreed by PAB regarding the current approach related to this period of time.

Please note that if you would like to follow further updates to this subject further information is available on the Monitoring the Settlement performance standards web page.

The consultation sets out the Settlement Risks identified for 2021/22, but we’d like BSC parties to let us know what they think of these risks and if they should be amended.
