AEMC Commissioners are appointed by Australia’s state, territory and federal governments to make the rules under the national energy laws, and to advise governments on overall energy market development.

The Commissioners exercise the AEMC’s statutory rule making and market development functions, subject to some delegations as explained below. Most of the functions relating to the management and day-to-day running of the organisation are the responsibility of the Chief Executive and the Executive Leadership Team. The Commission retains the majority of the statutory rule making powers and market development functions, and is also responsible for the AEMC’s strategic direction.

The Commissioners review the corporate governance framework of the organisation, overseeing the development of the AEMC’s strategic priorities and business planning, and approving corporate development initiatives as proposed by the Chief Executive with the Executive Leadership Team. The Commission holds monthly organisational meetings to review operational matters. In terms of risk management and reporting, the Commissioners review the AEMC’s budget, monitor its financial performance, and consider and approve the annual financial statements.

In February 2018 the COAG Energy Council welcomed the appointment of Mr Charles Popple and Ms Allison Warburton as AEMC Commissioners. Mr Popple's term commenced on 17 February 2018 and Ms Warburton's term commenced on 12 March 2018.
