CATL and Quinbrook deepen their Supernode battery‑storage partnership after completing phase 2 operations and securing A$469 million for phase 3, strengthening Australia’s large‑scale storage pipeline
Executive summary: CATL and Quinbrook announced that Quinbrook’s Supernode battery storage project completed commercial operation of phase 2 and closed A$469 million of financing for phase 3. It marks advancement of large‑scale battery storage in Australia, signals strong investor confidence in long‑duration storage, and deepens the strategic tie between CATL and Quinbrook.
Who is involved: Contemporary Amperex Technology Co. Ltd. (CATL), Quinbrook Infrastructure Partners, the Supernode project.
Likely next: Progression to construction and commissioning of Supernode phase 3, potential further financing rounds, and expanded CATL battery supply agreements for the project.
Quinbrook's Supernode project has reached a significant inflection point with the completion of phase 2 operations, which are now generating revenue, and the concurrent closing of A$469 million in financing for phase 3. The dual milestone not only validates the commercial viability of large‑scale battery storage in Australia but also cements CATL's position as the primary technology provider for the venture, reinforcing a supply relationship that spans multiple development stages. The sizable capital commitment reflects growing institutional appetite for long‑duration storage assets that can underpin grid reliability as renewable penetration deepens. By securing funding before construction begins, the partners reduce execution risk and set a clear timeline for adding further capacity to Australia's expanding storage pipeline, which is critical for meeting both state‑level renewable targets and national emissions goals. With financing in place, phase 3 construction is expected to commence in the near term, and the partners have indicated a roadmap for additional phases that could extend the project's total capacity. Successful delivery of these subsequent stages will provide a template for replicable, utility‑scale storage deployments across the National Electricity Market, potentially accelerating the transition to a firmed renewable grid.
