Construction of the 300MW, 1200 megawatt hour (MWh) battery is now past the halfway mark, with important energisation milestones achieved and strong progress across construction, commissioning and compliance activities. Yurika’s civil and electrical works are nearing completion in several areas of the site, paving the way for the next phase of commissioning.

At 1200 MWh, the Stanwell Battery ranks among the largest battery energy storage systems in Queensland and is a major step in diversifying the energy mix at the Stanwell Power Station precinct. Cooling towers and turbine halls that have powered Queensland homes and industries for decades now share space with modern battery units, showing how old can meet new in our changing energy landscape.

The project has also recently demonstrated strong performance in safety and regulatory compliance, successfully passing external audits and reinforcing the Yurika project team’s commitment to safe, high‑quality delivery.

Batteries have changed the game for energy systems, making it possible to store energy when it is abundant and release it when demand peaks. Fast, flexible and reliable, the Stanwell Battery will provide significant firming capacity to the Central Queensland electricity grid, responding in fractions of a second to support grid stability.

Stanwell’s power stations are already connected to the grid and supported by experienced teams and robust infrastructure. Building battery storage at these existing sites is efficient and practical, creating a launchpad for the next generation of energy storage in Queensland.

The project is to commence operations in January 2027. Yurika is engaged as the Principal Contractor with work including the turnkey design, engineering, procurement, factory inspections and testing, delivery, construction, start-up, commissioning and testing of all plant and equipment for the Balance of Plant (BoP) works. BoP is the process of connecting and integrating the battery and the renewable energy it generates into the electricity grid.
