The Western Australian Government is taking significant steps toward a cleaner, more reliable, and affordable energy future with over $1 billion in contracts awarded for massive battery energy storage systems in Kwinana and Collie.

Contemporary Amperex Technology Co Limited (CATL) has secured contracts to supply approximately 300 EnerC Plus containerised liquid-cooling battery systems for Kwinana Battery Stage Two and around 650 EnerC Plus units for Collie.

Power Electronics will be responsible for delivering 72 inverters for the Kwinana battery and 160 inverters for the Collie battery, the government said in a media statement. 

Kwinana Battery Stage Two is set to provide 200 megawatts of power with 800 megawatt hours of energy storage. Construction began in June and is slated for completion by the end of 2024, supporting 160 jobs.

Meanwhile, the Collie battery will become Western Australia’s largest, providing 500 megawatts with 2,000 megawatt hours of storage and creating about 500 jobs during the peak of construction.

These battery systems will facilitate the integration of more renewables into the energy grid by storing excess wind and solar energy generated during the day and releasing it during periods of high demand.

These contracts are part of the state government’s $2.8 billion budget commitment to advancing renewable energy projects.

Premier Roger Cook commented on the developments, saying the contracts, totalling more than $1 billion, represent a major and important investment by the government into WA’s cleaner, reliable, and affordable energy future. 

“Battery energy storage systems will play a key role in our decarbonization plans, storing excess renewable energy generated in the day and discharging during times of high demand,” Cook noted.

The premier also added, “We’re putting WA on the path to becoming a global green energy superpower, which is good for jobs, good for the environment, and will keep our economy strong into the future.”

Meanwhile, Energy Minister Bill Johnston stated, “Contemporary Amperex Technology is a global leader of new energy innovative technologies, providing more than 600 battery units for Kwinana Battery Stage One, which is now storing energy and discharging into the grid.” 

“Power Electronics is a leading manufacturer of inverters for photovoltaic plants and battery applications and a world leader in energy storage,” Johnston said. 

He also complimented Synergy on obtaining these important partnerships, which distinguishes WA as a leader in the global energy transition.
