CATL said Quinbrook’s Supernode energy storage Phase II has entered commercial
operation and Phase III’s A$469m financing has closed. Phases I–II
(520MW/1,858MWh) are now fully commercial; after Phase III the project’s total
capacity will exceed 3GWh, making it the largest operating battery storage asset
in Australia’s National Electricity Market (NEM). CATL is the project’s sole
supplier; Phase III will exclusively deploy CATL’s Tianheng storage system and
CATL and Quinbrook will jointly develop 8‑hour long-duration storage solutions.
CATL has installed a unified standardized technical platform at the site to
remove multi-phase equipment compatibility risks and support full-cycle safety
and efficient operations.
