Battery energy storage systems work by storing electrical energy and releasing it back into the grid on demand, stabilising supply during peak periods and supporting the integration of renewable energy generation.
A utility-scale BESS uses large banks of lithium-ion batteries, managed by control systems that direct when to charge, store, and discharge energy to the network. By responding quickly to changes in demand, it plays an important role in keeping Australia's electricity supply stable and reliable.

Like other utility scale facilities, BESS facilities can generate some sound. The main source of the sound is the cooling fans that regulate the temperature of the individual battery cells. The sound they make is similar to an air conditioning unit or a dull whirring noise. Detailed noise studies are undertaken by specialist consultants during the development process to ensure that any noise generated is within the relevant environmental noise guidelines and limits. Once operating, BESS facilities must continue to meet strict noise requirements which are set out in the planning process and other relevant noise protocols and/or guidelines.
A BESS uses proven and safe lithium-ion battery technology – similar to what you would find in your mobile phone or laptop computer – to provide reliable, clean, affordable electricity. To date, independent technical experts have not identified any known direct health impacts associated with BESS facilities.
When a BESS reaches the end of its life (around 30 years), the facility can be decommissioned (shut down). The BESS operator will remove the BESS facility and related infrastructure and rehabilitate the site. This will be a condition of the BESS facility's development approval from the State government and our agreement with the landowner. During decommissioning most of the materials the BESS is made from can be reclaimed or recycled.
