Monitoring and auditing performance


This page will tell you about the different ways we we keep track of your performance and any non compliance with the Balancing and Settlement Code (BSC) code. 

How we monitor your performance and any potential risks?

We conduct a handful of activities to help us ensure that parties are adhering to their BSC obligations and do not breach the BSC code.  These include:

  • Material Error Monitoring – this process is used to analyse settlement data and supplementary data to estimate and track identified material errors; it also helps us rank customer performance in the market and identify operational issues
  • Technical Assurance of Metering (TAM) Systems – this involves a the Technical Assurance Agent (TAA) conducting individual inspection visits to monitor the compliance of Metering Systems with the requirements stated in the BSC. The audit provides a level of assurance that the metered values passed into Settlement represent actual consumption. 
  • BSC Audit – The BSC Audit is performed on all Parties above a certain size on an annual basis, it involves reviewing systems and business processes in order to provide a level of assurance that the calculations and allocations that have been performed within CVA and Supplier Volume Allocation (SVA) are in accordance with the BSC and its subsidiary documents.
  • Technical Assurance of Performance Assurance Parties (TAPAP) – we may visit you to investigate a process which is potentially causing a risk to Settlement. 

How we report potential risks to the customer

There are a number of reports that provide feedback on the results of techniques. 

Technical Assurance of Metering (TAM) findings reports

The TAA Annual Report provides the Technical Assurance Agent’s view on the health of the Half Hourly metering population in the SVA and CVA markets. If you have had more than 25 TAA inspections during the audit period, you will receive your individual annual customer reports.

BSC Audit findings report

The BSC Auditor presents the Annual BSC Audit Report to the BSC Panel in June each year and individual and confidential Audit Issue documents will be sent to selected organisations.

Technical Assurance of Performance Assurance Parties (TAPAP) findings reports

After every Technical Assurance audit we produce a non-confidential findings report that is presented to the PAB and published on the website.
