Performance Assurance Reports

The reports on this page provide feedback on the results of some of the Performance Assurance Techniques. They feed into the Annual Performance Assurance Report (APAR).

If you want to read previous years’ reports please email us at paa@elexon.co.uk.

Annual Performance Assurance Report (APAR)

The Annual Performance Assurance Report:

  • provides the results of the risk evaluation and risk assurance procedures, in particular how well the techniques mitigated the Settlement Risks;
  • sets out the costs of ELEXON implementing the techniques;
  • recommends changes to existing techniques or recommends creating new techniques; and
  • explains the benefits of changing the Performance Assurance Techniques

Performance Assurance Framework Key Performance Indicators

ELEXON will report on the KPIs quarterly, at the same time as the full update on the Performance Assurance Techniques (PATs) is presented to PAB in the TPR. The KPIs will then be published on the Performance Assurance section of the website. The PAB approved the final set of revisions to the KPIs at the April PAB meeting.

Market Issue Documents

Market Issue documents detail matters raised by the Auditor for the industry’s attention. They capture widespread concerns which affect all organisations operating in a certain role.

The following are non-confidential versions of the Market Issues.

BSC Auditor’s Summary of Market Issues

——————————————————————————–

Materiality Report

The BSC Auditor produces a Materiality Report to explain how it determines the materiality of the key issues in the Annual Report. It also covers the distribution of these errors across Settlement. In 2009/10 a number of the key issues previously reported have improved to the extent that they are no longer in the Statement of significant matters. Therefore no Materiality Report was produced. Similarly no reports were produced for the 2010/11 and 2011/12 BSC Audits.

 

TAA Annual Report – Half Hourly Metering Systems

The Technical Assurance of Metering (TAM) technique monitors compliance of 100kW metering HHMS registered in Settlement as Measurement Class C, as documented in the BSC and its subsidiary documents including the Balancing and Settlement Code Procedures (BSCPs) and metering Codes of Practice (CoPs).

The Technical Assurance Agent (TAA) Annual Report provides the TAA’s view on the health of the Half Hourly metering population in the SVA and CVA markets. It is based on the findings from the inspections of Technical Assurance of Metering Systems and is used to highlight key market issues, particularly those with high potential materiality or risk to the quality of data used in Settlement.

If you have had more than 25 TAA inspections during the 2015/16 audit period, you will receive your individual annual customer reports, and will also be offered a chance to discuss your individual findings with ELEXON and the TAA.

We also produce individual confidential reports for Registrants (of Metering Systems) and Meter Operator Agents who receive 25 or more visits during the year.
