Community batteries
What is a community battery?
A community battery is a battery that can enable greater use of solar energy generated in the local community, enabling savings for local residents.
Community batteries can store solar energy generated in local neighbourhoods, enable lower electricity costs for consumers, and support the continued growth of low-emissions household solar on the electricity network.
The community batteries installed by Endeavour Energy are connected directly to the electricity network. Some of Endeavour Energy’s community batteries are mounted onto electricity poles, and all others sit on the ground.
How does a community battery work?
The high uptake of rooftop solar has seen households generate large amounts of energy during the day but it’s also created a new challenge. The excess solar has created congestion on the electricity network – a bit like when there’s too many cars causing a traffic jam, making it slow to get to your destination. It's the same when there’s too much solar in the electricity grid. It can create a backlog on the electricity grid.
A community battery puts this excess energy to good use. It works a bit like an energy bank where it can store excess solar generated by rooftop panels and then share it back with the community.
Are community batteries safe?
Safety underpins everything we do at Endeavour Energy, and we maintain the same commitment to safety for community batteries as we do for all our network assets. Community batteries operate within Endeavour Energy’s network. L ike all our assets, community batteries undergo stringent engineering and design approvals before installation. Additionally, Endeavour Energy has emergency response plans in place to handle any unforeseen situations.
Are community batteries noisy?
Our community batteries comply with NSW rules, regulations and guidelines for noise. Noise from the batteries comes from the air conditioning units attached to them.
Potential noise impacts to the community have been assessed as part of our location review process. Noise assessments are conducted before installation to ensure compliance with noise guidelines. For batteries installed on the ground, we have installed noise-reducing equipment to minimise impact.
Community battery trial
Where are the locations for the batteries and how did you choose these areas?
Batteries can provide support to Endeavour Energy’s network area by reducing overloading on the network, helping to manage voltages, improving network resiliency, and increasing the capacity for solar exports from customers.
Locations selected for batteries are areas where the network is currently experiencing, or is expected to experience, problems that could be addressed by batteries. The locations have also been selected based on their high percentage of residents with rooftop solar panels, to improve opportunities for customers to participate in the community battery program.
How many batteries are being installed as part of this program
The Shell Cove Community battery is part of our larger trial in partnership with Origin Energy. Our first community battery was launched in Bungarribee Blacktown last year, with this battery now fully subscribed. Community batteries are now being delivered to communities of the Campbelltown, Kiama, Liverpool, Shoalhaven, Wingecarribee and Wollondilly local government areas, subject to waivers from the Australian Energy Regulator.
Does Endeavour Energy have plans for more community batteries beyond this program
Endeavour Energy is participating in government community battery grant programs to enable us to roll out batteries to more communities. Under the Commonwealth Batteries for Household Solar program, we will deliver a further 44 community batteries across Blaxland, Hobartville, Bidwill, Cabramatta, Warrawong and Dapto by March 2025.
Program registration
What is required to participate in the community battery trial?
Participation is voluntary. You need to be the owner or lessee at the supply address and the premises at that address needs to be connected to the electricity grid. We will assess whether participation in right for you and calculate the savings you may receive from participating in the trial.
I don’t have solar. Can I still participate?
Absolutely. Even if you don’t have solar panels, you will be able to join the community battery as long as you live in an eligible battery catchment area.
I rent the property, can I still participate and benefit from the community battery?
Yes. Community batteries are open to customers regardless of whether you own or rent the premises at the supply address.
Participating in the program
What amount of storage can I access?
In the interest of fairness and providing as many customers with access to cheaper household energy as possible, we have set an initial battery capacity limit at 4 kWh per household per day. Our current research tells us most households will at least use this amount of energy most evenings, therefore making it the most efficient capacity for the most amount of customers - distributing the benefits as widely as possible through our communities.
What does it cost and what are the financial benefits for me?
Customers will be charged a monthly participation fee of $15, which will entitle them to reserve capacity of up to 4 kWh each day. Customers can then draw up to this same amount of energy back from the battery per day.
As customers supply and, or just source their energy from a community battery, they will receive a rebate. The rebate will reflect the savings they have generated by sourcing some of their daily energy needs from the battery rather than the grid.
We estimate that participating customers who both store and draw energy in and from the community battery could receive a potential rebate of up to $300 per annum, even after their payment of the participation fee is accounted for.
The exact amount of rebate you could receive will depend on:
- whether you have a home solar system or not
- the size of your solar system
- your usage patterns
- the time of the year (as electricity use varies over summer, autumn, winter and spring)
- for homes with rooftop solar, the amount of excess solar energy you export to the network.
What happens if I move before the end of the trial?
No problem. Simply contact us and you can withdraw from the trial at any time, with no financial penalties payable for doing so.
How will I receive my rebate for participating in the community batteries trial?
Origin Energy will calculate your rebate and deposit the amount directly into your nominated bank account. This will be done on a monthly basis.
What happens to the rebate I already earn from my excess solar energy?
Yes you will continue to get this rebate from your electricity retailer. Your participation in this trial is completely separate and has no impact on your existing electricity arrangement with your retailer.
The trial is expected to demonstrate that you can get more value out of your existing excess solar production by storing that energy and using it at times when prices are higher in the national electricity market – such as at night when the sun isn’t shining.
Retail partner
How is Endeavour Energy working with Origin Energy on this initiative?
Endeavour Energy will buy and install the community batteries, providing the necessary infrastructure. Origin Energy will support with the offering to customers and be the retail partner in this initiative.
Do I need to be a customer of Origin Energy to participate?
No. You do not need to be an Origin Energy electricity customer to participate in the community batteries trial. Your participation in the trial relates to energy storage services and is separate to any electricity agreement you have with your current electricity retailer.
Do I need to notify my energy retailer that I am joining the community batteries trial?
No - your retail arrangements will remain unchanged. Your participation in the trial relates to energy storage services and is separate to any electricity agreement you have with your current electricity retailer.
