RES is proposing to develop a battery energy storage system (BESS) facility near Bunyip North, north of the Princes Freeway, approximately 3km from Bunyip, in the Cardinia Shire.

The BESS would have a power capacity of up to 400 megawatts (MW) and a storage capacity of up to 2,400 megawatt-hours (MWh) — enough to supply around 138,000 homes at times of peak demand.

The Project is designed to support the sustainable transition of Victoria's energy network, enabling greater integration of renewable energy and reducing reliance on fossil fuels to maintain grid reliability.

The planning application is now on public notice. 

To view the documents for the Bunyip North BESS on the Ministerial permit register, visit PA2604370.

The Responsible Authority will not decide on the application before 21 August 2026.

To learn more, including how to make a submission, see the formal public notice (Form 2) or visit Planning Pathway & Timeline.

In planning for Australia's clean energy future, RES acknowledges its rich history. We pay our respects to the Bunurong people of the Kulin Nation, the Traditional Custodians of the Country on which the Bunyip North Energy Storage Project is proposed. We recognise their ongoing connection to land and waterways and pay our respects to their Elders past and present.
