The Australian Energy Market Commission (AEMC) has made a draft rule to modernise distribution network planning in a system increasingly driven by consumer energy resources (CER).
Rooftop solar, batteries and EVs are transforming how networks are used, creating both opportunities for consumers and challenges for the grid.
To keep pace with this shift, planning needs to be backed by clearer, more accessible data on how and where these technologies are being used.
Greater visibility can help meet the growing demands of consumers and reduce the need for costly network investments.
The draft rule introduces a new distribution network development plan to support more proactive, long-term planning.
Importantly, it also includes a new data reporting framework to improve visibility of the network and help unlock the value of CER.
AEMC Chair Anna Collyer said the reform will give decision-makers across the energy system better information to act earlier.
“With detailed visibility of where solar, batteries and EVs are emerging, DNSPs and investors can plan ahead through targeted upgrades or non-network solutions.” Ms Collyer said.
“That means fewer constraints, less curtailment of rooftop solar, and ultimately more efficient investment decisions that flow onto everyone’s power bills.”
“It’s like upgrading the planning tools from an old street directory to Google Maps, where we can see more clearly, respond earlier and ensure the grid works for everyone.”
A key focus of the draft rule is boosting visibility of the low-voltage network to provide a more granular view of what’s happening right down to the street.
That level of insight helps identify the best spots to install EV chargers, community batteries and other local energy solutions.
Other proposed enhancements
- Standardised data reporting across DNSPs to improve consistency and transparency.
- Flexible data reporting requirements that can evolve with new technologies and services.
- Stronger stakeholder engagement in network planning processes.
Network costs make up close to half of a typical electricity bill so it’s vital that the planning and reporting framework is fit for purpose.
Updating network regulation to support improved consumer outcomes is one of the AEMC’s four key priorities for this financial year. The draft rule also aligns with the direction of the National CER Roadmap.
What happens next
The AEMC is seeking stakeholder feedback before publishing a final determination and rule, expected in mid-2026.
Submissions are due 4 June 2026.
