Annual Market Advisory Committee Composition Reviews
Under clause 2.3.9 of the WEM Rules, the Coordinator of Energy must annually review the composition of the MAC and may remove and appoint members following the review.
The review process is outlined in the MAC Constitution, provided under the MAC Governance Documents section above.
The Coordinator completed the 2024 MAC Composition Review on 29 January 2024 and appointed MAC Members to fill vacancies of the MAC. This will maintain the balance of energy producers and retailers on the MAC. These appointments are reflected in the MAC Membership list published above.
A fulsome review of the MAC has now commenced to assess whether the:
- MAC is fit for purpose, and in particular, that it operates efficiently and provides balanced, timely and useful advice to the Coordinator;
- MAC operates for the good of the WEM Objectives;
- MAC members are participating in the interests of the stakeholder groups that they represent rather than on representing the specific interest of any organisation or person; and
- The review will also account for the expanded scope of the WEM Rules and the expanded range of subject matter that the MAC will be required to provide advice on.
Depending on the outcomes of the review, the composition and Constitution of the MAC, including the number and class of Market Participants may be amended. Further information on the review of the MAC is available here.
Further information on the 2024 MAC Composition Review and all previous reviews can be found on the Past Market Advisory Committee Annual Composition Reviews page.
