Australia's energy transition will only succeed if consumers understand it, trust it and can participate without needing to become energy experts.
That was the central message from Australian Energy Market Commission (AEMC) Chair Anna Collyer during her keynote address at Australian Energy Week, where she outlined a reform agenda focused on simplifying electricity pricing, improving consumer participation and ensuring new technologies deliver benefits without driving up costs.
Rather than focusing solely on generation and transmission, Collyer argued the next phase of the transition must put households and businesses at its centre.
Reflecting on her five years leading the AEMC, she said the Commission had remained committed to being forward-looking, pragmatic and collaborative.
That means tackling some of the energy market's most contested issues before they create greater costs for consumers.
"We've also been challenged by our stakeholders to be bolder, to use our role and bring the sector together on hotly contested questions, where those questions posed really very real and serious risks to consumers if we don't find a path forward together now.”
The centrepiece of Collyer's address was an early preview of the AEMC's long-awaited electricity pricing review.
She argued electricity pricing has become increasingly difficult to navigate as more households install rooftop solar, batteries and electric vehicles.
Sharing her own experience of installing a home battery, Collyer admitted that even as Chair of the AEMC she found comparing electricity plans surprisingly difficult.
"I tried to understand all the different rates... there was really a lot to consider, and it was pretty complex and very time consuming."
If someone with deep market knowledge struggled, she said, the challenge was far greater for pensioners, busy families and students trying to reduce their electricity bills.
The Commission's proposed solution is to shift much of that complexity away from consumers and towards retailers and energy service providers.
Rather than expecting households to understand network tariffs, export charges and time-of-use pricing, retailers would package those costs into simpler products suited to different customer needs.
To explain the concept, Collyer compared electricity to buying milk.
Consumers do not need to understand every cost involved in producing and transporting milk before deciding which carton to buy. Electricity, she argued, should be no different.
The proposal would not remove incentives for flexible energy use. Consumers willing to allow technologies such as batteries to optimise their electricity use should continue sharing in the financial benefits, while those who simply want predictable bills and straightforward pricing should also have that option.
Importantly, Collyer stressed the reforms would not happen overnight.
The pricing review contains recommendations only. Any rule changes would require further consultation before implementation, with reforms likely to be introduced gradually over the coming decade.
"The alternative... is that the current arrangements gradually become more costly, more confusing, and very much harder to unwind."
Beyond pricing reform, Collyer highlighted the rapid growth of data centres as one of the biggest emerging challenges for the energy market.
While Australia has a significant economic opportunity to attract investment, she said data centre development must not leave existing energy consumers worse off.
The AEMC is currently updating technical standards for large inverter-based loads and advising energy ministers on arrangements requiring future data centres to offset electricity demand through renewable generation, firming and demand flexibility.
Drawing on lessons from overseas, including North America and Ireland, Collyer said large new electricity loads must be planned, connected and operated as part of the broader power system.
"We can't pursue that opportunity at the expense of other energy consumers, especially when so many are under real cost-of-living pressures."
Electric vehicle charging presents a similar balancing act.
The AEMC is considering several rule change proposals examining the role of network businesses in supporting charging infrastructure while ensuring consumers are not paying more than necessary.
Collyer also pointed to broader reforms underway to modernise electricity networks as millions of households increasingly generate, store and export electricity.
With network costs accounting for up to half of the average power bill, she said better planning, improved data and updated regulatory frameworks would help identify where solutions such as community batteries or local energy projects could deliver greater value than traditional network upgrades.
Throughout the address, Collyer returned to a consistent theme: the energy transition is not simply about building new infrastructure, but about designing a system that consumers can confidently navigate.
"It's about giving Australians more control and better choices in this energy transition... to empower them to take advantage of change rather than consumers simply feeling as though change is happening to them."
As Australia's electricity system becomes increasingly decentralised and technology-driven, Collyer's message was clear: lasting success will depend not only on engineering and investment, but on creating an energy market that is simpler, fairer and built around the needs of consumers.
