Governance documents
The ESM Rules outline the functions and composition of the MAC, as well as the procedures for appointing new members. The ESM Rules require the Coordinator of Energy (Coordinator) to develop and publish a Constitution for the MAC.
Following the Coordinator’s Review of the MAC (the Review) under clause 2.2D.1(h) of the ESM Rules, the Coordinator completed a review of the MAC Constitution in consultation with the MAC in accordance with clause 2.3.3 of the ESM Rules.
Stakeholder consultation on the changes to the MAC Constitution closed on 22 December 2025. Submissions received and EPWA’s response to these are available below.
The Amending Rules to implement the outcomes of the Review were included in the Electricity System and Market Amendment (Tranche 9) Rules 2025 which were approved by the Minister for Energy on 19 December 2025 and a notice of their making was published in the Government Gazette on 23 December 2025.
The Constitution for the MAC has now been amended, as required under clause 2.3.3 of the ESM Rules, to reflect the changes to the ESM Rules following the MAC Review.
The amended MAC Constitution is available below.
