Australia's Supernode Battery Storage Project Hits Major Financing and Operational Milestones

## Australia's Supernode Battery Storage Project Hits Major Financing and Operational Milestones Quinbrook Infrastructure Partners and CATL, the world's leading battery manufacturer, have announced a series of significant milestones for Australia's Supernode battery energy storage project, including the completion of Stage 2 commercial operations and the financial close of A$469 million in funding to advance Stage 3 of the phased development. According to a PR Newswire release dated 15 August 2026, the Supernode project — based in Brisbane, Australia — represents one of the most ambitious grid-scale battery energy storage initiatives in the Asia-Pacific region. The successful completion of Stage 2 commercial operation signals that the project is delivering on its development timeline, while the Stage 3 financing milestone underscores continued institutional confidence in large-scale energy storage infrastructure. ### Strategic Significance for Energy Transition The Supernode project is widely regarded as a bellwether for Australia's broader energy transition, as the country works to integrate increasing volumes of renewable generation into its national electricity grid. Large-scale battery storage assets play a critical role in stabilising grid frequency and providing dispatchable capacity — functions that are directly relevant to port electrification and shore power initiatives being pursued by maritime operators across the region. For the maritime industry, developments of this scale carry particular relevance. Australian ports are under growing pressure to decarbonise landside operations and provide clean power to vessels at berth. Reliable, grid-scale battery storage infrastructure is a prerequisite for delivering the consistent, high-capacity shore power connections that modern container and cruise vessels require. ### CATL and Quinbrook Partnership The partnership between Quinbrook — a specialist renewable energy and storage investment manager — and CATL reflects a broader trend of battery manufacturers taking active roles in project development, rather than simply supplying technology. CATL's involvement brings both technical credibility and supply chain certainty to the Supernode project at a time when battery procurement timelines remain a key risk factor for large infrastructure developments. The A$469 million Stage 3 financing package represents a substantial vote of confidence from lenders in the project's commercial fundamentals and the durability of the Quinbrook-CATL partnership. Further details on the Stage 3 construction timeline and projected operational capacity are expected to be released as the project progresses through its next development phase. *Source: PR Newswire*
