The Balancing and Settlement Code (BSC) Audit is a key
detective technique. It’s designed to provide assurance that the Settlement
and Funding Share calculation provisions are complied with.
The BSC Auditor is a BSC Agent procured and managed by ELEXON. The BSC Auditor is
currently PricewaterhouseCoopers LLP.
BSC Audit Issue Documents and Audit Survey
The 2009/10 Audit Year is now complete and we’re sending Audit Issue Documents to
Audited Entities this week.
In line with our ongoing efforts to deliver the best service to the industry, we’d
like your feedback on the process. Our BSC Audit questionnaire on the BSC Audit
is an opportunity to tell us about your experiences over the last Audit year, covering
the period 1 April 2009 to 31 March 2010.
Click here to access the BSC Audit Feedback Questionnaire. Please complete this
survey by Monday 2 August 2010.
We value your feedback, and your comments will help us to improve the quality of
our service to you.
For more information on the survey or the BSC Audit, please contact
bscaudit@elexon.co.uk.
What happens during the Audit?
The BSC Panel sets the scope of
the BSC Audit each year. Following this, the BSC Auditor develops an Audit Approach
which describes how it will deliver the work required to meet the scope.
Below are copies of the current BSC Audit Scope, BSC Audit Scope Diagrams and non-confidential
version of the BSC Audit Approach. Contact ELEXON if you require previous versions.

The Audit Cycle follows an annual
Audit Cycle of planning, site visits and reporting.
Further information is available in the
BSC Audit Process Fact Sheet (69Kb)
.
What happens after the Audit?
The BSC Auditor presents his Annual BSC Audit Report in June each year to the BSC
Panel. Individual and confidential BSC Audit Issue Documents (BSCAIDs) are distributed
to Parties and Party Agents. Market Issues relating to specific market roles can
be located on the
Performance Assurance Reports Page
What does a 'Qualified' BSC Audit Opinion mean?
The BSC Auditor will ‘Qualify’ its audit opinion if it cannot provide reasonable
assurance that the total level of error in Settlement is less than the Materiality
Threshold. The Materiality Threshold is currently 1.65TWh which represents approximately
0.5% of the total annual electricity supplied across Great Britain.
Related Audits
The BSC Audit incorporates the Funding Shares Audit and takes account of the findings
of the Balancing Mechanism (BM) Audit performed by National Grid’s Auditor. The
BM Audit looks at the data submitted and used for balancing the system.
You can download the BM Audit Report from the National Grid website.
I’m about to be Audited - what do I need to know?
Your OSM and the BSC Auditor will be in touch with you to discuss the audit process,
and answer any questions you may have. You will be offered a planning meeting to
talk about arrangements for the site visit and any data requests.
We offer an on-line tool, the BSC Audit Communications System, which is a secure
central repository for BSC Audit documentation and you can use it to share information
with the BSC Auditor and ELEXON. You can upload, view and download information relating
to the Audit.
You can access the BSC Audit Communications System via
the ELEXON Assurance Portal. If you want to use this facility please email
bscaudit@elexon.co.uk.
Annual BSC Audit Reports
The BSC Auditor produces several reports each year outlining the findings of the
BSC Audit work. These reports are available from the
Performance Assurance Reports page.
BSC Audit Issue Documents
Individual Issue Documents are raised by the BSC Auditor to highlight issues identified
during its work. Individual documents are raised against Suppliers, Supplier Agents,
Supplier Meter Registration Agents, BSC Agents (in relation to the Central Systems)
and ELEXON. You receive your Issue Documents once you’ve agreed and accepted the
content. If you’re not a BSC Party you’ll need a Hold Harmless Letter in place before
you receive your Issue Documents. Visit the
Hold Harmless Letters page for more information.
Audit Peer Comparison
During the BSC Audit Terms of Reference Review 2009, an Expert Group examined how
performance under the BSC Audit could be measured, to incentivise Audited Entities
to reduce non-compliances.
We have put together a scoring mechanism, and compiled the results for each market
role, based on data from the 2008/09 Audit Year which is published on the
BSC Audit Issue Resolution page.
