Quinbrook has selected GE Vernova to provide technology for the third stage of the Supernode battery energy storage system (BESS) project in Queensland, Australia, expanding its involvement to all three phases of the development.
The agreement will see GE Vernova deliver power conversion, plant controls, system integration and grid-connection support for stage three.

The Supernode site is located adjacent to the South Pine substation, a central component of Queensland’s electricity transmission network. The facility stores electricity during times of surplus and dispatches it back into the grid when demand rises or renewable output fluctuates.
This process supports dependable power supply and allows for greater integration of renewable energy sources into the network.
The first and second stages, which also used GE Vernova technology, are now fully operational and are among the largest BESS facilities running in Australia’s National Electricity Market.
Stage three is set to contribute an additional 260MW and 1.22GW-hours (GWh) of storage, bringing the total capacity of the Supernode campus to 780MW and 3.08GWh once completed.
Quinbrook has confirmed that the third stage recently achieved Generator Performance Standards acceptance, a key step required for grid connection.
GE Vernova Electrification segment Power Conversion & Storage business leader Ed Torres said: “Supernode shows what is possible when storage, power conversion and intelligent controls work together at scale. Our engineering and integration work helped Supernode Stage 3 secure Generator Performance Standards acceptance.
“This important grid-connection milestone demonstrates the strength of our technology and our ability to support complex projects in Australia’s demanding grid-connection environment. We are proud to expand our partnership with Quinbrook and bring grid-forming technology to Australia.”
Grid-forming technology included in phase three will enable batteries to contribute to system stability and provide services traditionally delivered by conventional power stations, including frequency support.
Prior to this, Quinbrook and CATL completed commercial operations for stage two of the Supernode BESS project and secured A$469m ($332.9m) in funding for the financial close of stage three.
