Wandoan Battery Energy Storage System is a utility-scale energy storage project located in Queensland, developed to strengthen grid stability and support the increasing penetration of renewable generation within the National Electricity Market.
The project integrates large-format battery units with power conversion systems and high-voltage connection infrastructure, enabling rapid response to network frequency fluctuations and peak demand events. By storing excess generation and dispatching energy when required, the facility enhances reliability while supporting more efficient operation of the broader transmission network.
Delivery of Wandoan BESS required coordinated engineering, protection and control design, grid compliance studies, and close engagement with AEMO and the relevant Network Service Provider to satisfy performance standards and commissioning requirements.
Key project elements include:
• Battery storage system installation and integration
• Power conversion systems and transformer infrastructure
• High-voltage connection and substation works
• Protection, control, and SCADA systems
• Testing, commissioning, and compliance verification
Wandoan BESS plays a strategic role in supporting renewable integration, improving system strength, and contributing to a more resilient and flexible electricity network.
