Batteries in place for $625M Kwinana Battery Stage Two

Battery systems are now in place for the $625 million Kwinana Battery Stage Two project in Western Australia.

Synergy has installed the containerised battery systems at what will be WA’s biggest grid-connected battery energy storage system.

The Kwinana Battery Stage Two project will deliver the second grid-scale battery energy storage system in Kwinana, which will aim to deliver cleaner, reliable and affordable energy for the region.

Kwinana Battery Stage Two will provide 200 megawatts of energy capacity with 800 megawatt hours of energy storage – four times that of Kwinana Battery Stage One.

This system will comprise of 288 shipping container sized battery modules and will feature 72 inverter units. These inverter units will be used to support grid stability by storing electricity when demand from the grid is low, delivering it back into the gird during peak times.

When complete, the new battery system will be capable of powering 370,000 average homes across the State for approximately four hours.

Synergy Newly installed battery systems at Kwinana Battery Stage Two were supplied by Contemporary Amperex Technology Co. Limited (CATL). Power Electronics has been contracted to provide the 72 inverters.

Western Australian Premier Roger Cook said the installation of the new battery systems was an important milestone in the State’s energy transformation.

“WA is a leader in the uptake of residential solar energy, and these big batteries help to ensure our energy system remains reliable as we transition away from coal-fired power,” he says.

“It is particularly fitting that we’re building the infrastructure of future at the site of the old Kwinana Power Station – keeping the Kwinana industrial strip front and centre as our energy system transitions to a new future.”
