Australian households and businesses could see a collective reduction of up to $1.1 billion on their energy bills in the coming years, following the Australian Energy Regulator’s (AER) release of its draft 2026 Rate of Return Instrument (RORI) on 31 August 2026. This critical consultation process directly influences how much electricity and gas network companies can charge consumers for their infrastructure investments. In a separate but related decision on the same day, the AER also moved to cap gas disconnection fees for Victorian households at $220, significantly reducing a potential barrier for those looking to electrify their homes.
These recent announcements underscore the AER’s ongoing efforts to balance necessary network investment with consumer affordability, particularly as Australia navigates its energy transition.
What is the Rate of Return Instrument (RORI)?
The Rate of Return Instrument (RORI) is one of the most fundamental regulatory decisions influencing energy prices in Australia. It sets the allowed rate of return for electricity and gas network businesses, determining the revenue they can recover from consumers for their investments in poles, wires, and pipelines. This rate of return is a crucial component of network charges, which typically account for a significant portion of a consumer’s total energy bill.
“It’s one of the most important decisions influencing how much Australian households and small businesses pay for energy, and many people don’t know about it.”
By consulting on the 2026 RORI, the AER aims to ensure that network companies are compensated fairly for their services without overcharging consumers. The current draft decision proposes changes that the AER estimates could result in substantial savings for households and small businesses across the National Electricity Market (NEM) and regulated gas networks. The consultation period allows stakeholders, including consumer advocacy groups, to provide feedback before a final decision is made.
The $1.1 Billion Impact on Your Bills
The AER’s estimate of $1.1 billion in potential savings reflects a proposed reduction in the rate of return networks are allowed to earn. This directly translates to lower network charges on energy bills over time. While the final figure may adjust after the consultation period, the intent is clear: to alleviate cost pressures on consumers.
Historically, network costs have been a significant and often opaque component of electricity and gas bills. By scrutinising and potentially lowering the allowed rate of return, the AER aims to foster greater efficiency and ensure that consumers are not burdened with excessive charges for essential infrastructure upgrades and maintenance. These savings would be distributed across millions of households and small businesses in New South Wales, South East Queensland, South Australia, Victoria, Tasmania, and the ACT, where the AER’s regulatory framework applies.
Victorian Households See Relief on Gas Disconnection Fees
In a targeted decision on 31 August 2026, the AER also released draft decisions for Victorian gas distributors, specifically addressing the cost of permanently disconnecting from the gas network. The draft ruling rejects proposals from distributors that would have allowed them to charge customers around $1,000 for abolishing a gas connection. Instead, the AER proposes a cap of $220 for individual customers, with any remaining costs to be recovered from the broader customer base (socialised across all gas users).
This decision is a significant win for Victorian homeowners looking to transition away from gas and electrify their homes, a move often motivated by rising gas prices and environmental concerns. The previous high disconnection fees acted as a deterrent, adding an unexpected cost to energy efficiency upgrades. For those considering a full shift to electric appliances, such as reverse-cycle air conditioners for heating and cooling or induction cooktops, this clarity and reduction in cost provide welcome certainty.

Broader Context: Network Costs and the Energy Transition
Network charges are a complex part of Australia’s energy pricing structure, reflecting the cost of building, maintaining, and operating the vast infrastructure that delivers electricity and gas. As Australia transitions to a cleaner energy system, significant investment is required in new transmission lines, distribution networks, and smart grid technologies to integrate more renewable energy sources and manage decentralised generation like rooftop solar and home batteries.
The AER’s role is to ensure these investments are prudent and efficient, preventing network companies from passing on unjustified costs to consumers. The RORI is a key mechanism for achieving this. Lowering the cost of capital for network companies ultimately means lower charges for consumers.
What This Means for Your Energy Bill
While the $1.1 billion in savings from the RORI is an estimate and subject to final determination, it signals a positive direction for energy affordability. For individual households and businesses, the direct impact will vary based on their consumption, location, and energy plan. However, a reduction in underlying network costs should flow through to retail prices over time.
Consumers are encouraged to remain proactive in managing their energy costs. This includes regularly comparing energy plans to ensure they are on the most competitive offer.

The AER’s current focus on network cost efficiency, coupled with specific consumer-friendly rulings like the Victorian gas disconnection cap, reflects a broader regulatory commitment to ensuring a fair and affordable energy future for all Australians.
