The Australian Energy Market Commission (AEMC) has this week unveiled a draft determination proposing significant updates to the regulatory framework governing gas networks, a move intended to safeguard consumers from escalating costs as the nation transitions away from gas. Released on August 26, 2026, the draft package introduces a new 20-year outlook to sit alongside the existing five-year regulatory framework, aiming to provide greater transparency and better tools for regulators to manage the long-term decline in gas demand.

This policy shift comes as thousands of Australian households and businesses are actively converting from gas to electricity, driven by rising energy costs and a growing commitment to decarbonisation. The AEMC’s proposal is designed to facilitate an orderly, consumer-led transition, ensuring that those who remain connected to the gas network are not unfairly burdened with the costs of an increasingly underutilised system.

“Our draft package lays the foundations for an orderly, consumer-led transition that puts households and businesses in the driver’s seat,” stated AEMC Chair Anna Collyer. “Despite uncertainty about future gas demand, government policies and transition timelines, we cannot afford to delay action; it will only allow the problem to grow, become more costly, and harder to resolve.”

The Challenge of Declining Gas Networks

Australia’s gas networks face a unique challenge: as more consumers switch to electric appliances for heating, cooking, and hot water, the fixed costs of maintaining the extensive gas pipeline infrastructure are spread across a shrinking customer base. This dynamic threatens to push up individual gas bills for remaining customers, creating a ‘death spiral’ where higher prices accelerate the exodus, further exacerbating the issue. The AEMC’s draft determination aims to pre-empt this by introducing mechanisms that ensure prices remain reasonable over the long term, particularly for vulnerable consumers.

Key Proposals in the Draft Determination

The AEMC’s draft package includes several key reforms:

  • 20-Year Outlook: A new long-term planning horizon will require gas network service providers and regulators to consider the long-term impacts of the energy transition on customer services and costs. This aims to identify issues early and allow for timely responses.
  • Enhanced Transparency: New requirements will mandate greater transparency from service providers regarding network usage, investment plans, and transition strategies.
  • Cost Alignment: Measures are proposed to better align the recovery of network costs with the expected use of the network over time. This includes strengthening existing provisions to minimise unnecessary expenditure being passed from networks to consumers, by using forecast demand, instead of solely relying on existing demand, to justify costs.
  • Improved Regulatory Tools: The Australian Energy Regulator (AER) will be equipped with better tools to oversee gas network planning and investment decisions in a declining market.

The AEMC anticipates that these changes, once implemented, will begin to impact consumer costs and network management by mid-2027, providing a clearer pathway for both the industry and consumers.

Industry and Consumer Group Reactions

While the AEMC frames its proposal as a proactive measure, it has not been met with universal approval. Energy Consumers Australia (ECA) expressed “profound disappointment,” arguing that the draft determination “would leave consumers left holding the tab for Australia’s shrinking gas networks.” ECA CEO Dr Brendan French criticised the AEMC’s approach, stating that despite acknowledging consumer risks, the proposed rule would “weaken the regulator’s ability to control price increases” and effectively “shift power away from the regulator and toward businesses that are asking consumers to pay more, faster.”

ECA, alongside the Justice and Equity Centre, had previously proposed rule changes aimed at ensuring fair treatment for consumers transitioning away from gas. Their concerns highlight a tension between ensuring network viability and protecting consumers from the costs associated with the transition.

Broader Implications for Australia’s Energy Transition

This draft determination underscores the complexities inherent in Australia’s rapid energy transition. As states like Victoria continue to lead the charge in residential electrification, the policy challenges of managing legacy fossil fuel infrastructure become increasingly pressing. The shift away from gas impacts not only household bills but also the broader energy ecosystem, encouraging greater adoption of electric alternatives.

For households considering the switch, understanding these regulatory developments is critical. The long-term trajectory points towards a predominantly electric future, making decisions around home heating and appliance choices increasingly important for managing future energy costs. For those looking to reduce their reliance on gas, exploring efficient electric alternatives can lead to substantial annual savings.

Furthermore, as more homes embrace rooftop solar and battery storage, the integration of these consumer energy resources (CERs) is becoming central to grid stability and efficient energy use. Policies that support a robust and flexible electricity grid will indirectly benefit all Australians by facilitating more renewable energy generation and potentially lowering wholesale electricity prices.

The AEMC’s draft determination is now open for public consultation, with stakeholders encouraged to provide feedback before the final determination is made. The outcome will significantly shape how Australia manages the economic and social impacts of its accelerating energy transition, aiming to balance network stability with consumer protection in a rapidly evolving market. These policy decisions will directly influence the effectiveness of future energy bill relief initiatives for Australians.
