The Liddell Battery project comprises the development of a 500-megawatt / 1,000-megawatt hour grid-scale battery (BESS) on the site of the former Liddell power station - which retired in 2023.
The project is to be delivered over three stages:
- Stage one: decoupling works to faciliate new connection following the retirement of the Liddell power station.
- Stage two: delivery of the BESS.
- Stage three: ancilliary works to Bayswater power station.
