The Deniliquin Battery Energy Storage System (BESS) Flood Assessment is an iconic project supporting the transition to renewable energy while ensuring resilience to local flood risks. This study is unique in that it integrates advanced hydrologic and hydraulic modelling, site-specific flood behaviour analysis, and compliance with regional and state floodplain management plans to enable the safe development of large-scale energy infrastructure.
The project confirms that the BESS site will operate without increasing flood risk to surrounding properties or infrastructure, while incorporating measures to ensure safe access and minimal environmental impact. Currently underway, the assessment represents an important milestone in balancing energy security, climate adaptation, and community safety, with outcomes that will help guide the future of sustainable infrastructure across the region
This assessment ensures the BESS site operates safely without increasing flood risk, setting a benchmark for sustainable infrastructure in the region.
The Deniliquin BESS is proposed to be located 6 km southeast of Deniliquin, NSW, adjacent to the Deniliquin substation.
