Quinbrook has reached financial close on $469 million financing for Stage 3 of the Supernode Battery project in Queensland, marking a further milestone in the phased development of Australia’s largest operational BESS campus.
With planned capacity expected to exceed 3GWh, Supernode is supported by CATL as its core energy storage system supplier for all three stages, providing advanced storage solutions and lifecycle support to enable reliable long-term operation.

Located at Brendale, north of Brisbane, Supernode is adjacent to the South Pine substation, a key hub in the Queensland power system and the regional reference node for marginal loss factors (MLFs).
This location provides a favourable MLF position and approximately 4,000MW of available connection capacity for phased expansion. The project’s development coincides with Queensland’s accelerating energy transition and the infrastructure investment cycle.
Financial close of Stage 3 brings total project financing across Supernode Stages 1, 2, and 3 to approximately $1.2 billion. Across its first three stages, Supernode is set to reach 780MW/3,074MWh. Capacity across the three stages has been contracted under long-term offtake arrangements.
The long-term value of such assets depends on the continued availability, operational efficiency, safety and reliability of their energy storage systems. CATL has provided EnerC Plus systems for Stages 1 and 2 and will supply TENER S systems for Stage 3, establishing a consistent technology platform across the campus.
CATL will further support the full lifecycle of the energy storage asset through condition monitoring, performance tracking, fault response and preventive maintenance to help ensure reliable long-term operation.
Quinbrook managing director and regional lead Australia Tim Hornemand said, “Achieving commercial operations for Stage 2 means we’ve successfully delivered both Origin-contracted stages on schedule, an outcome we’re incredibly proud of given the complexity of commissioning utility-scale battery storage projects in Australia.

“With Stage 3 now fully financed, we’ve reached another important milestone in Supernode’s continuing development. The ongoing support of our banking partners also reflects confidence in the Supernode project, our delivery track record and the long-term outlook for battery storage in Australia.”
CATL and Quinbrook are also working together on EnerQB, an eight-hour battery storage solution being considered for future stages of the Supernode development.
