Changing the way we use the local electricity distribution grid can provide Australians with cleaner and cheaper energy, according to a new report from Energy Networks Australia.
The Time is Now report shows that there are opportunities within the distribution grid that can be unlocked and enabled now, to deliver more benefits for customers.

Energy Networks Australia CEO Dom van den Berg said we must look beyond the traditional role of distribution networks as just poles and wires.
“Findings show that if we act now to get the distribution grid doing more heavy lifting, customers can save around $160 per year and avoid $7 billion in overall system costs in 2030 alone. The nation will also be better positioned to achieve its 82% renewables target by 2030,” she said.
“We absolutely need to make sure we are pulling all levers. That includes keeping focused on the large-scale renewable projects and the vital transmission infrastructure we need to connect them. While we do that, it also makes good sense to do everything we can at a local level to bring down bills and provide more services to customers.
“We must get smarter with how we use existing infrastructure, how we maximise rooftop solar, how and where we store and manage it locally, and how we get more EV chargers in more places.
“There is a clear opportunity to get the local grid doing more of the heavy lifting in the energy transition and achieve greater savings for customers by 2030, but that window of opportunity is closing.”
The report calls for changes that can be delivered today through the right policy decisions, and fit-for-purpose regulatory settings. The recommendations include:
- Link local energy hubs by linking locally-generated solar with unused capacity in the grid to operate as ‘local energy hubs’ for all the community to benefit from.
- Amplify untapped solar opportunities by introducing incentives for large commercial properties to install more solar panels on existing rooftops and share it with the local community.
- Soak up the surplus solar by having large batteries attached to the existing grid infrastructure so that local customers get the full benefits of solar and grid connected batteries.
- Plug in more EV chargers by enabling networks to install and maintain kerbside (power poles) charging at pace to put more chargers in more places, ensuring an equitable rollout of chargers and reducing customers’ range anxiety.
- Sync with the grid by connecting and coordinating all energy resources so that we better utilise our existing poles and wires, while maximising the benefits to customers.
