Renewable energy retailer and project developer Flow Power has announced plans for a State Significant Development project in Corowa, New South Wales.
The proposed project is a 100MW/200MWh Battery Energy Storage System that will enhance grid reliability, support renewable integration, and deliver long-term social and economic benefits to the local community.
The proposed Corowa Battery will be located at 275 Whitehead Street, behind the existing Corowa Substation, with a project footprint of approximately 2–3ha. Once operational, the battery will store enough energy to power the equivalent of all homes in the Federation Council area, with around 13,000 residents, for a full day.
The Corowa site was selected for its location adjacent to existing high-voltage transmission infrastructure, which reduces environmental impact by eliminating the need for additional transmission lines and ensures efficient connection to the grid.
With growing solar generation from local rooftops, commercial facilities and the nearby Corowa Solar Farm, large-scale energy storage will help balance supply and demand, ensuring renewable energy can be better integrated and utilised across the grid.
Flow Power Head of Community and Stakeholder Engagement, Kait Williamson, said the project would strengthen the local grid while creating lasting economic and social value for the region.
“This is an exciting project for the Corowa Community, and for New South Wales,” Ms Williamson said. “We’ve been listening closely to the local community, council, neighbours and businesses, and are committed to delivering a project that strengthens the local grid, while creating lasting economic and social value for the region.”
The Corowa Battery will store energy generated within the region, including renewable energy from local solar projects, and release it during periods of high demand. This will contribute to more affordable, reliable, and sustainable energy for everyone.
By capturing and storing energy generated locally without the need for additional transmission lines to the project, the battery will also help postpone the need for costly network upgrades, which will contribute to reduced long-term costs for electricity customers. The proximity to existing energy infrastructure will also reduce the potential impact on the local landscape.
Flow Power is working with local stakeholders and Federation Council to co-design Community Benefit Initiatives. These include a Neighbour Benefit Program valued at up to $250,000 for residents within 1km of the project site, and a proposed $800,000 Community Enhancement Fund, which will exceed New South Wales government recommendations.
The project is set to deliver significant regional investment to the area, including around 70 construction jobs and ongoing maintenance opportunities, with a focus on prioritising local workers and suppliers to further strengthen the local community connection.
Flow Power is currently progressing through the New South Wales Department of Planning, Housing and Infrastructure’s State Significant Development process. In June 2025, a Scoping Report was submitted, and Flow Power is now preparing a detailed Environmental Impact Statement for submission before the end of the year.
The Environmental Impact Statement will include independent technical assessments covering noise, visual impact, bushfire risk, traffic management, and social and economic impacts. Once complete, the Environmental Impact Statement will be placed on public exhibition for community feedback.
Flow Power has been engaging closely with the Corowa Community to understand and address local concerns, particularly around noise, visual impact, traffic and fire safety.
To reduce both noise and visual impacts, landscape screening, such as walls, trees, and shrubs, will be installed to create an effective buffer. Early technical assessments indicate that noise levels will comply with NSW noise guidelines, and the landscape and visual impact assessment is currently underway.
“Community consultation is central to the delivery of our projects,” Ms Williamson said. “Feedback from local residents will continue to shape key design elements to ensure the Corowa Battery delivers positive outcomes for the community and local environment.”
As the project timeline progresses, Flow Power will continue its engagement with Federation Council, local residents and community groups. The Environmental Impact Statement will be available for public review later this year, via the New South Wales Major Projects planning portal, where community members can make submissions and provide feedback.
