The West Australian government has signed one of the nation's largest renewable energy deals to purchase two massive battery storage systems worth more than $1 billion.
The systems will be installed at the industrial hub of Kwinana, about 40km south of Perth, and the coal-producing town Collie, in WA's southwest.
They will allow for more renewable wind and solar energy to be stored for use during high-demand periods.
About 950 EnerC Plus containerised liquid-cooling battery systems and 232 inverters will be supplied under the deal.
Premier Roger Cook said the contracts were an investment in cleaner energy production and a major step towards WA's net zero emissions by 2050 target.
"Battery energy storage systems will play a key role in our decarbonisation plans, storing excess renewable energy generated in the day and discharging during times of high demand," he said.
"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."
Kwinana Battery Stage Two will provide 200 megawatts of power with 800 megawatt hours of energy storage.
Construction on Kwinana Battery Stage Two started in June and is estimated to be completed at the end of 2024, supporting 160 jobs.
The Collie battery will be the biggest in WA providing 500 megawatts with 2000 megawatt hours of storage.
It will also create about 500 jobs during the peak of construction.
A battery energy storage system with 2800 megawatt hours of storage is estimated to be capable of supplying 175,000 homes with on-demand energy.
