Australians could see significant reductions in their electricity bills, with new modelling from the Australian Energy Market Commission (AEMC) revealing that reforms to how electricity network costs are recovered could deliver up to $6 billion in savings over the next 15 years. Released on 22 April 2026, the analysis indicates that some households could save as much as $740 annually on their electricity bills by 2040.

This landmark modelling, based on over 400 million real data points from households across ten distribution networks, underscores the potential for a more efficient and equitable energy system. The proposed reforms aim to modernise network charging, shifting away from outdated structures that no longer reflect the evolving energy landscape, particularly with the rise of rooftop solar and home batteries.

“Australia’s energy system has changed dramatically over the past decade. Consumers are now generators, sending power back to the grid from solar panels and batteries, and the way we charge for the network needs to keep pace with that change.”

— Anna Collyer, AEMC Chair

The AEMC’s analysis projects that most households, regardless of whether they have solar or batteries, would benefit from these reforms. Notably, approximately two-thirds of households currently unable to install solar or batteries are also expected to be better off. This is a crucial aspect, as it addresses concerns about equitable access to the benefits of the energy transition. The projected savings of $40 to $80 per household per year by 2040 specifically account for network cost reductions.

The Drive for Reform: Outdated Pricing vs. Modern Grid

The current network pricing structures often fail to accurately reflect the true cost of using the grid at different times. As more households adopt rooftop solar and battery storage, they interact with the grid in new ways, sometimes reducing their reliance on grid power during peak demand periods and even exporting excess electricity.

The AEMC’s push for reform acknowledges that the traditional ‘poles and wires’ costs, which constitute a significant portion of an electricity bill, need to adapt. By aligning network charges more closely with actual grid usage patterns and the benefits customers provide to the system (e.g., through solar exports), the reforms seek to incentivise efficient energy use and investment in distributed energy resources. For households looking to maximise their savings, understanding how to avoid peak demand charges will become even more critical.

Broader Context: AER’s Draft Default Market Offer

This AEMC modelling comes amidst broader discussions about electricity pricing in Australia. The Australian Energy Regulator (AER) released its draft Default Market Offer (DMO) for 2026-27 on 19 March 2026, proposing potential price reductions for residential and small business customers on standing offers across New South Wales, South East Queensland, and South Australia. These proposed reductions, ranging from 1.3% to 10.1% for residential customers and 7.6% to 21.2% for small businesses, were largely attributed to lower wholesale electricity costs and reduced environmental and retail operating costs.

For example, under the AER’s draft decision, residential prices in New South Wales could decrease by 2.4% (approximately -$58) to 8.2% (approximately -$226), depending on the distribution zone. Small business prices in the state could fall by 7.6% (approximately -$379) to 21.2% (approximately -$1,320). In South East Queensland, residential prices were projected to drop by 10.1% (approximately -$216), and small business prices by 12.8% (approximately -$550). South Australian residential customers could see a 1.3% (approximately -$31) decrease, while small businesses might benefit from a 15.2% (approximately -$845) reduction.

Furthermore, the AER’s draft determination also introduced the concept of a “Solar Sharer Offer” (SSO), an opt-in tariff that would provide three hours of free power during the middle of the day for households with smart meters in DMO regions. This initiative, set to be available from 1 July 2026 in NSW, SA, and SE QLD, is designed to leverage abundant solar energy and help households reduce bills by shifting their energy use.

Protecting Vulnerable Consumers

While the AEMC’s modelling highlights significant potential savings, it also acknowledges that some consumers could face higher bills if the reforms are implemented without safeguards. To address this, the AEMC has commissioned independent analysis from HoustonKemp Economists to identify practical options for consumer protection. For instance, a small Sydney florist with low overall electricity consumption could see their bill increase by up to $810 by 2040 under the modelled scenario before any consumer protections are applied. This underscores the need for targeted measures to ensure no household is left worse off.

The AEMC has not yet reached final recommendations, with all findings and over 2,700 submissions to be considered before the Final Report is published in June 2026.

Implications for Households and Businesses

The ongoing reforms and proposed changes signal a dynamic period for Australian energy consumers. For those considering investments in home energy solutions, these developments reinforce the value of efficient appliances and renewable energy technologies.

The focus on network efficiency and demand-side management means that actively managing energy consumption will continue to be a key strategy for bill reduction. As winter approaches, understanding effective ways to reduce heating bills will also be crucial for many Australians.

This latest modelling from the AEMC provides a clear indication that a more equitable and cost-effective energy future is within reach, provided the right reforms and consumer protections are put in place.
