Evoenergy is trialling six new community-scale batteries in Denman Prospect to help improve electricity reliability during Canberra’s high-demand winter season.
One battery was installed in March 2025, with five more scheduled to be installed by late May. These batteries are the first of their kind in the ACT and are designed to store energy from the grid during off-peak periods – like overnight or midday – and release it when demand is highest, especially in the evenings when heating use peaks.
Each battery delivers 300kW/600kWh of energy storage, which is equivalent to around 44 home batteries. They provide a flexible and innovative way to support reliability now, while Evoenergy progresses permanent network upgrades, including the planned Molonglo zone substation.
The batteries are fully enclosed, actively monitored, and meet strict safety and performance standards. Temporary fencing, signage, and protective systems are in place at each site. This trial is part of Evoenergy’s commitment to delivering safe, reliable and innovative energy solutions for Canberra’s growing communities.
Frequently asked questions:
-
What do the batteries look like?Each battery is similar in size to half a shipping container – approximately 3 metres long by 2 metres tall. They are housed in a single enclosed unit on the ground, surrounded by secure temporary fencing with Evoenergy-branded banner mesh and safety signage. Each battery connects directly to a nearby distribution substation via underground cables.
-
Why are these batteries being installed?The six community-scale batteries are part of a temporary three-month trial to support the electricity network during Canberra’s high-demand winter period. They store energy from the grid during off-peak times and release it when demand is highest – particularly in the evenings when heating use peaks. This helps balance the network, optimise available capacity, and improve reliability for the Molonglo Valley.
-
How safe are the batteries?The batteries are designed, built, and tested to meet stringent Australian and international safety standards. Each unit features advanced fire suppression, battery management systems, and protective casings. Evoenergy monitors the batteries remotely and performs regular on-site inspections. ACT Fire and Rescue and ACT Environmental Planning have been consulted to ensure compliance with all safety and regulatory requirements.
-
Are the batteries loud?The batteries produce a low to medium ‘whoosh’ sound – similar to a washing machine or office air conditioner. Noise levels will vary depending on weather and usage, but noise levels are minimal. For locations within 45 metres of homes, acoustic barriers are used to reduce sound impacts.
-
Can the batteries be moved if residents are concerned?No. Each site was carefully selected to maximise network benefit while minimising community impact. A detailed noise assessment was conducted, and sound levels will not exceed 35 decibels at 45 metres – comparable to a whisper at close range.
-
Is it safe to be near the batteries during operation?The batteries are securely enclosed, fenced off, and equipped with protective systems to prevent public access or accidental contact. While it’s safe to be nearby, do not attempt to touch the battery or enter the fenced area.
-
Can I use the battery during an outage?No. If there is a power outage in your area, the battery will shut down as a safety precaution. This prevents electricity from being unintentionally fed into the network and ensures the safety of Evoenergy crews working to restore power.
-
Why is the battery located close to homes?The batteries are positioned to support the electricity network in the Molonglo area. Their proximity to existing distribution substations enables them to supply more customers and provide the greatest reliability benefit to the surrounding neighbourhoods.
