BSC Audit Reports

Annual BSC Audit Report

The BSC Audit Report is produced every year by the BSC Auditor. Based on the assurance procedures the BSC Auditor performs, it highlights the key BSC Audit issues which have higher levels of potential settlement error or risk associated with them.

The Statement of Significant Matters (‘SSM’), which is included as part of the BSC Audit Report should be read in conjunction with the BSC Auditor’s assurance opinion. The SSM contains details of those issues that are judged as not being sufficiently material to be included in the BSC Auditor’s assurance opinion but which, the BSC Auditor believes are appropriate to bring to the attention of the recipients of the BSC Auditor’s Report.

KPMG, as the BSC Auditor has completed the Report for the audit of the calculations and allocations performed in relation to Settlement from 1 April 2014 to 31 March 2015. A summary of the Auditor’s findings for the 2014/15 Audit Year is as follows:

The BSC Audit

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.
