Alinta Energy to build 100MW Australian 'big battery'

Alinta Energy is to build a 100MW two-hour ‘big battery’ at its Wagerup Power Station to help stabilise and backup the grid in South West Western Australia.

Alinta has appointed Shanghai Electric Power Design Institute and Sunterra to deliver the battery by early 2025.

Works at the site, located around 120 kilometres south of Perth, will commence immediately.

Ken Woolley, Alinta Energy chief development officer, said: “This project is a great example of how Alinta Energy, Western Power, AEMO and our key supply partners are rapidly mobilising to ensure the electricity system in South West WA has the smoothest transition to renewables possible.”
