In an innovative move towards sustainable infrastructure management, a pioneering field trial is underway, focusing on the integration of battery energy storage systems at ten sewage pumping stations within the Shoalhaven Heads catchment, NSW. In partnership with Shoalhaven Water and supported by the ARC SafeREnergy Hub, the Australian Power Quality Research Centre (APQRC) is developing battery backup systems to enhance the performance, safety, and reliability of critical sewage pumping and distributed infrastructure. Currently in the installation phase with four sites already equipped, this initiative marks a crucial step forward in understanding how battery storage can contribute to energy resilience in critical infrastructure applications. The next crucial phase involves a comprehensive data analysis of site performance, setting the stage for groundbreaking insights into energy solutions for sewage management.
