Neoen builds its sixth big battery in Australia

French renewables giant Neoen will start building its sixth big battery in Australia. The battery will be the company’s first major project in Western Australia.

It will also be Neoen’s first 4-hour long-duration battery globally. Long-duration storage is increasingly needed as the world transitions to renewable energy.

Helping Western Australia decarbonise

The 219 MW / 877 MWh battery will be located near the town of Collie in the southwest region of Western Australia. It will connect to Western Power’s Shotts Terminal substation. The battery’s construction will create around 120 jobs and opportunities for local suppliers.

The Collie Battery will enable Neoen to fulfil a services contract awarded by the Australian Energy Market Operator (AEMO).

The contract will run for 2 years from 1 October 2024. It will provide 197 MW of storage capacity for 4 hours, charging during the day and then discharging across the evening peak. This will address the risks around the retirement of coal power plants and increasingly high penetration of rooftop solar in Western Australia.

‘This is an exciting time for Neoen as it is our first major project in Western Australia,’ says Louis de Sambucy, Neoen Australia’s CEO. ‘With our growing team in Perth and a strong pipeline of projects, we look forward to playing an increasingly significant role in the state’s rapid decarbonisation.’

The battery is expected to start operating in Q4 2024.
