In order to reinforce the Market Participants' confidence in the transparency and adequacy of the operation of the WESM, the PEM Audit Committee (PAC) conducts, coordinates and supervises the independent audits of the operations, processes and systems of the market, the Market Operator and the Central Registration Body (CRB). The PAC, in consultation with Metering Service Providers (MSP), also reviews the security arrangements and requirement of WESM and Retail metering installations.
To ensure sufficient and adequate expertise, the PAC engages, through PEMC, the services of qualified independent persons, firms and/or consortiums, who shall act as the External Auditor for the said audit and metering review.
The first operational audit on the systems and procedures of the Market Operator was conducted in 2010 while the first metering arrangements review on WESM and retail MSPs was conducted in 2012.
