Flow Power has announced plans for a second large-scale battery at its Bennetts Creek Battery project while breaking ground at the site where construction is set to begin on Stage 1.
Held at the Bennetts Creek Battery project site opposite Morwell Terminal Station on Gunaikurnai Country, the celebration recognised progress on what is set to become Flow Power’s largest Battery Energy Storage System (BESS).

Bennetts Creek Battery will be a 100MW/223MWh BESS project with a footprint of approximately 2.3ha, and is expected to begin operations in 2028. Once operational, it will support the integration of existing renewable energy generation into the Victorian grid during peak times and help place downward pressure on wholesale electricity prices.
Delivery of the Bennetts Creek Battery project is supported by Wärtsilä, which will provide battery technology and intelligent control systems, and Zenviron, which is responsible for balance of plant design, construction, installation and commissioning.
Bennetts Creek Stage 2 is proposed to be located alongside the existing Bennetts Creek Battery site at Monash Way, Morwell. The project will deliver up to 300MW/1.2GWh of additional energy storage.
Stage 2 is currently in the early planning phase, with Flow Power undertaking initial environmental, noise and cultural heritage investigations. An application for Development Approval is being prepared for the Department of Transport and Planning, and Flow Power is seeking community input as part of the consultation process.
The Latrobe Valley region was selected for both projects due to its industrial zoning and strong proximity to existing grid infrastructure. The area’s transmission network was originally built to host some of Victoria’s largest and earliest generators, many of which are reaching end of life and scheduled to retire over the coming years.
Flow Power chief operating officer Byron Serjeantson said the event marked an important moment for both the company and the state’s clean energy transition.
“Today’s celebration marks an exciting milestone for Bennetts Creek Battery and for Flow Power’s continued investment in Victoria’s energy future,” he said.

“Projects like this are critical to supporting the integration of more renewable energy into the grid, while helping deliver the reliable and affordable energy households and businesses need.”
