2026 RATE OF RETURN INSTRUMENT REVIEW UPDATE
On 28 March 2025, the Australian Energy Regulator (AER) announced that come July 2025, it will commence a review to make the 2026 rate of Rate of Return Instrument (RORI) by December 2026. The AER has also published the RORI review process paper, which sets out the review process to be followed in making the 2026 RORI.
Under national energy laws, the AER must make a RORI every 4 years. The RORI, which is binding on network business and the AER, specifies how the AER will determine the allowed rate of return on capital invested in regulated electricity and gas networks. The return on capital is a key driver of the total amount of revenue network businesses derive from network revenue determinations made by the AER. It is calculated by multiplying the rate of return to the value of the regulatory asset base.
Any changes in the rate of return or how it is calculated will likely affect retailers who may pass on any increase in the rate of return to end consumers.

DRAFT RULE TO INCREASE CREDIT SUPPORT OPTIONS
On 3 April 2025, the Australian Energy Market Commission (AEMC) published a draft rule determination that would expand credit support options available to participants in the National Electricity Market (NEM).
The draft rule seeks to amend the credit support arrangements in the NEM to increase optionality and flexibility for market participants by:
- allowing participants to provide cash as credit support up to a limit of $5 million each;
- allowing participants to provide surety bonds as credit support; and
- broadening the pool of acceptable credit support providers.
The draft rule would particularly benefit small and prospective retailers, who typically have higher financing costs and lower access to capital.

DRAFT RULES TO ENHANCE SAFEGUARDS FOR ENERGY CONSUMERS
On 27 March 2025, the AEMC published two draft determinations aimed at enhancing safeguards for energy consumers.
The first draft determination responds to a rule change request from Energy Ministers to increase support for consumers experiencing hardship. It aims to:
- increase support and improve outcomes for hardship consumers so that they are no worse off if they do not take up their retailer’s deemed better offer;
- place a stronger onus on retailers to assist hardship consumers with deemed better offers but afford retailers flexibility in delivering these protections; and
- improve the reporting and transparency of hardship offers available to consumers.
The second draft determination consolidates four rule change requests into one rule change process focused on improving confidence in retail energy plans. It seeks to:
- protect consumers from paying higher prices for their loyalty by ensuring they pay no more than the standing offer price when their energy plan's benefits expire;
- remove unreasonably high penalties for not paying bills on time;
- restrict retailers from increasing prices in market retail contracts more than once every 12 months; and
- prohibit fees and charges for vulnerable consumers and limit fees and charges to reasonable costs for all other consumers.
The AER is seeking stakeholder feedback on both draft determinations by 8 May 2025.

GAS PIPELINE MONITORING AND TRANSPARENCY REPORT
On 26 March 2025, the AER published the first gas pipeline monitoring and transparency report that provides insights into the behaviour and compliance of pipeline service providers.
Some of the key findings include:
- limited transparency in prices charged by service providers for pipeline services;
- shippers reported different experiences in their ability to negotiate non-price terms and conditions with service providers;
- financial information reported by service providers (mandatory from December 2025) will improve transparency and enable cost-based pricing benchmarks to be calculated using a building block approach;
- 11 access negotiations with prospective shippers seeking access to pipeline services were reported, all of which resulted in new access agreements;
- the AER did not have any compliance concerns regarding service providers’ dealings with associates;
- responses to the 2023 and 2024 voluntary information requests indicated service providers had complied with all ring-fencing requirements, except for one instance of self-reported noncompliance; and
- service providers have complied with the requirements under the National Gas Law and National Gas Rules.
VICTORIAN ENERGY EFFICIENCY TARGET AMENDMENT (ENERGY UPGRADES FOR THE FUTURE) BILL 2025
The Victorian Energy Efficiency Target Amendment (Energy Upgrades for the Future) Bill 2025 (Vic) (Bill), which seeks to amend the Victorian Energy Efficiency Target Act 2007 (Vic), has commenced second reading at the Legislative Council.
The Bill will, among other things, make it easier for electricity and gas retailers to comply with their obligations to buy and surrender certificates by making the Victorian Energy Upgrades program flexible by removing technical restrictions on the creation and surrender of certificates.
