Flow Power plans to build the $135 million facility on a six-hectare site at 275 Whitehead Street, behind the existing Corowa Substation.
The battery would have a capacity of 100 MW/200 MWh, enough to power all homes in the Federation Council area for a day.
The project is in addition to European Energy’s 30-megawatt BESS planned for Mulwala, sufficient to power about 20,000 homes.
Construction on the Mulwala battery is expected to begin mid-2026, subject to approvals.
Flow Power’s head of project development, Mark Raymond, said the Corowa project was progressing through the NSW Department of Planning’s State Significant Development approval process.
He said the battery would help stabilise the electricity grid by storing excess renewable energy and releasing it when demand is high.
Initial meetings have been held with nearby residents, businesses and council representatives with plans to host a second community information day in late November.
“We want to make sure people understand how the project works, what the benefits are, and how we’re managing any potential impacts,” Mr Raymond said.
“The battery is designed to charge during the day when solar output is high, and release energy during evening peaks.
“This means more efficient use of renewable power already in the system.”
An Environmental Impact Statement to assess noise, bushfire, and social and economic impacts is being prepared and is expected to be submitted to the NSW Department of Planning, Housing and Infrastructure in late 2025 or early 2026.
Flow Power hopes construction would start in 2027 generating about 70 jobs, with completion expected by mid-2028.
Federation Council general manager Adrian Butler said the council welcomed early engagement from Flow Power and would continue to monitor the proposal through the planning process.
He said council encouraged residents to take part in consultation opportunities.
“It’s positive to see major renewable energy projects being proposed in our region,” Mr Butler said.
“Council’s role is to ensure the planning process carefully considers local impacts, particularly around land use, amenity, and community benefit.”
“We’d urge community members to review the Environmental Impact Statement once it’s on exhibition and provide feedback, so local views are reflected in the assessment.”
Mr Raymond said Flow Power would continue to engage with the Corowa community as plans progress with details of the community event to be advertised locally.
