This 500 MWh grid connected Battery Energy Storage System supports large scale energy storage and grid flexibility in Gnarwarre, Australia. The facility is designed with a power capacity of 250 MW along with 2 hours of storage backup, enabling strong support for energy shifting, primary frequency response and ancillary services. The project contributes to the region’s renewable energy transition by storing excess generation and releasing power when required to stabilise the grid. It includes detailed electrical engineering, safety planning and operational procedures aimed at supporting reliable commissioning and long term operation. The project is currently ongoing, with the early contractor involvement stage completed.
TCE's Scope
TCE delivered the complete detailed engineering for the 500 MWh Battery Energy Storage System. The scope included preparation of the full electrical system design, Single Line Diagram, Logic Diagram, Schematic Drawings and the Supervisory Control and Data Acquisition architecture in line with project requirements. TCE prepared equipment sizing calculations and developed the Request for Quotation and Technical Data Sheet for all major electrical equipment. The work also included Technical Bid Evaluation as per project guidelines and vendor document review for all electrical systems.
The scope covered preparation of the startup and shutdown procedure, the performance test procedure and the performance test report. TCE provided support for the cyber security assessment and completed the installation details for all major equipment except the Battery Energy Storage System itself.
The team also prepared the as built documentation for all TCE related engineering based on the site markup furnished by the site contractor and other involved entities. All deliverables are intended to be certified by a local Australian partner holding Chartered Engineer status.
Impact
TCE’s engineering work strengthened the project’s ability to deliver flexible, responsive and reliable energy storage for the Australian grid. The detailed electrical design supports safe operation, efficient installation and clear equipment integration during commissioning. The performance procedures and start up and shutdown plans improve operational reliability, while the equipment specifications and vendor reviews ensure that major components meet the required standards for large scale storage.
The project contributes to grid stability and supports renewable energy adoption by enabling energy shifting, primary frequency response and ancillary services through a high capacity storage facility.
