Renew Economy:

Australia’s largest battery storage project could be built just outside of Sydney, with planning documents revealing the plans of renewable energy developer Neoen kick-starting the planning process for a 500MW/1,000MWh big battery in New South Wales.

Neoen submitted a scoping study for the project with the NSW Department of Planning, Industry and Environment shortly before Christmas, and is the first step in the planning process for what the company has dubbed the “Great Western Battery”.

In the study prepared with the support of consultancy AECOM, Neoen says that the project would form a major part of an evolving New South Wales energy grid, with the energy storage project capable of supporting the NSW state government’s plans to drive new investment into as much as 12GW of new wind and solar generation capacity by the end of the decade.

According to the scoping study lodged by Neoen, the ‘Great Western Battery’ would re-purpose existing network infrastructure previously constructed for the now decommissioned Wallerawang coal-fired power station. The 1,000MW Wallerawang coal power station was closed by EnergyAustralia in 2014, and Neoen’s proposed big battery would be able to connect to a 330kV substation that that had previously served the power station.

Neoen expects the project to involve an investment of between $300 and $400 million and would create up to 200 new construction jobs, with final figures to be determined as the planning process progresses. An indicative timeline suggests that construction of the battery could begin in 2022 with operation commencing by 2023.
