The Australian Energy Market Commission (AEMC) is an independent statutory body that works for Australia's future productivity and living standards by contributing to a decarbonising, affordable and reliable energy system for consumers.

We listen, make practical rule changes and provide expert advice in a rapidly changing world. We lead, collaborate, adapt and influence in making and amending rules for the National Electricity Market, elements of the natural gas market and related retail markets; and providing strategic and operational advice on energy issues to the Energy and Climate Change Ministerial Council.

The National Electricity, Gas and Retail Rules made by the AEMC have the force of law and under the National Energy Laws, all of the AEMC’s work is guided by the three legislated national energy objectives:

Each objective requires an explicit focus on the long-term interests of energy consumers in our rule making decisions and advice, in relation to price, quality, safety, reliability and security of supply, and emissions reduction. In doing this we understand how the rapidly changing context in which we operate affects the interests of consumers in the long term and the need to design a future-proof system accordingly. We account for significant shifts such as climate change impacts, technological change and market transformation, and the uncertainty that the interaction between these shifts creates in the sector.

“None of our decisions are taken lightly. The security, reliability and cost of energy underpins our quality of life.”

Energy is a key input to all sectors of the Australian economy. We recognise that decarbonised, affordable and reliable energy is a key enabler of improved consumer living standards. We work for a future where energy simply works for all consumers. Consumers do not worry about their energy bills. Consumers do not worry when they turn on a light switch or charge a device no matter where they are. Consumers do not worry about blackouts on hot days. Consumers do not worry about contributing to emissions.

By ensuring energy simply works for Australian businesses, we help the economy to grow sustainably and competitively, as well as providing certainty for investment, innovation and jobs.


Governance and history

The National Electricity Market (NEM) was established in 1998 and the AEMC was established in 2005.

The AEMC is one of three market bodies responsible for energy in Australia, all of which report to the Energy and Climate Change Ministerial Council (ECMC) through the energy ministers. 

The 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 are supported by the Chief Executive and the Executive Leadership Team and staff, and together they discharge rule making and market development roles in line with the AEMC’s Code of Conduct which requires AEMC staff to act with fairness, honesty, impartiality and integrity in all our dealings.


Rule making

Under the:

we make and amend the:

that underpin the National Electricity Market (NEM). These rules:

  • govern the operation of the NEM – the competitive wholesale electricity market and the associated national electricity system
  • govern how market participants can operate in gas and retail sectors
  • govern the economic regulation of the services provided by monopoly transmission and distribution networks and gas pipelines
  • facilitate the provision of services to retail customers and provide specific rights for consumers to whom energy is sold or supplied

The AEMC cannot propose rules (except for minor changes such as corrections). However any stakeholder including governments, industry participants and consumers can request rule changes.

Our role is to manage the rule change process and to consult and decide on rule change requests made by others. We do this in accordance with processes set out in the law, the central focus of which is the long-term interests of consumers.

Reviews and advice

Energy markets are adapting to changing circumstances, such as the transformation of the natural gas sector and growth in renewable and local generation. In accordance with the National Electricity Objectives, the AEMC undertakes reviews and provides advice to governments on improvements to regulatory and energy market arrangements, in order to provide consumers with reliable low-emissions energy in the most cost efficient way within this changing environment.

Many of our reviews arise from terms of reference provided by the nation’s energy ministers, but we can also initiate our own reviews on matters related to the rules.

In conducting our reviews and preparing advice we consult widely on matters which are related to the progress of the Energy and Climate Change Ministerial Council’s energy reform agenda.

Our current work and priorities 

The AEMC regularly monitors and reports on a range of matters including the level of competition in energy retail markets, future price trends, and energy market performance. We also seek to understand the impact on the energy sector of relevant policies – such as emissions reduction policies – and highlight any issues in our advice to help promote integrated and consistent policy outcomes.

As part of our technology-focussed work program, the AEMC also publishes papers and reports which inform our advice to governments and analysis of rule change requests.

Our priorities are threaded through multiple rule changes, reviews and advice.

The Reliability Panel, which forms part of the AEMC’s institutional arrangements, reviews and reports on the safety, security and reliability of the national electricity system.
