The IESO received a clean audit in an external audit that examined the Meter Data Management and Repository’s (MDM/R) operations, processes and procedures.

In its report, which covers the April 1, 2011 to September 30, 2011 audit period, PricewaterhouseCoopers LLP provided an unqualified opinion on the controls the IESO has put in place relating to the accurate, complete and timely processing of the MDM/R, and the security over electricity consumption information. The results found that:

• The controls that were tested operated with sufficient effectiveness to provide reasonable assurance that the control objectives were achieved during the audit period;
• The description of controls presented fairly, in all material respects, the relevant controls that were placed in operation as at September 30, 2011;
• The controls were suitably designed to provide reasonable assurance that the specified control objectives would be achieved.

An independent MDM/R audit is conducted every year to provide reasonable assurance to the MDM/R service recipients and their auditors that the IESO’s internal controls governing the operation of the MDM/R are suitably designed and effectively administered.

The MDM/R service recipients are responsible to obtain the report and review the scope, coverage and results to assess the extent of use of the report in meeting their needs.

MDM/R service recipients who have questions or would like a copy of the audit report may contact the SME.
