Construction is now underway on the second grid-scale battery storage system in Western Australia.
The $625 million Kwinana Battery Stage Two project will deliver 200 megawatts of energy capacity with 800 megawatt hours of energy storage – four times that of Kwinana Battery Stage One.
The project will play a key role in closing coal-fired power stations, as part of the Western Australian Government’s 2030 emissions reduction targets.
Construction on the second big battery will include 288 shipping container-sized battery modules and will feature 72 inverter units. These inverters use new-generation technology to support grid stability by storing electricity when demand is lowest and delivering it back into the grid during peak times.

Western Australian Premier Roger Cook said the start of construction marks an important milestone for the state.
“These big batteries help to ensure our energy system remains reliable as we transition away from coal-fired power,” Cook said.
Construction of the big battery is situated close to the old Kwinana Power Station site, adjacent to the first grid-scale battery.
The second big battery is expected to open by late 2024.
