Centalion, a leading global energy trading company, is expanding its APAC power platform through two connected transactions in South Australia: a long-term electricity supply agreement with Firmus Technologies for its planned AI infrastructure operations, and a long-term offtake agreement supporting GreenPoint Energy’s Koolunga Battery Energy Storage System (BESS) project. 

Together, the transactions establish an integrated supply model linking large-scale electricity demand with renewable procurement, flexible load capability and battery firming infrastructure, supporting Firmus’ long-term Australian energy requirements. 

Under the 12-year agreement, Centalion will supply electricity to Firmus’ South Australia operations from mid-2027 through supply arrangements designed to support Firmus’ long-term growth. As part of that structure, Centalion is committing to underwriting 1.2 GW of additional renewable generation and 1.5 GWh of new battery storage capacity by 2032, while incorporating demand flexibility during tight supply periods. In doing so, Centalion and Firmus will take the market and tenor risk needed to help unlock investment in the long-dated renewable and firming capacity required for the energy transitionEnergy Transition refers to the global shift from reliance on fossil fuels such as coal, oil, and natural gas towards more sustainable and renewable energy sources like solar, wind, hydroelectric,...

A key part of the initial firming portfolio is GreenPoint Energy’s Koolunga BESS project. At 200 MW / 800 MWh, Koolunga is expected to provide more than half of Firmus’ initial contracted battery firming requirement and represents the first major storage component supporting the broader Firmus–Centalion supply portfolio. 

Under the offtake agreement, GreenPoint Energy will secure long-term revenue support for the project, while Centalion will secure dispatchable storage capacity and risk managementRisk Management in the context of energy commodities trading refers to the identification, assessment, and prioritization of uncertainties followed by coordinated and economical application of resources to minimize, monitor, and... More capability to support customer delivery. Koolunga is targeted for commercial operations in Q1 2028 and is located adjacent to ElectraNet’s Brinkworth 275 kV substation in South Australia’s Mid North. 

The combined structure demonstrates how long-term customer demand can be coordinated with renewable procurement and firming infrastructure through a single commercial solution. For Centalion, the transactions represent another step in the expansion of its APAC power platform and provide a model for future customer-led energy solutions across the National Electricity Market. 

Executives from each of the companies involved commented on the deal in June: 

“The AI revolution will be built on energy infrastructure, and this agreement shows how commodity traders can play a critical role in making that future possible. This milestone underscores the evolution of our company into a broader energy solutions provider—one that can mobilize capital, manage risk, and deliver physical supply to support strategic infrastructure projects,” said Aldo Della Valle, Global Head of Power & Natural GasNatural Gas Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane (CH4), but commonly includes varying amounts of other higher alkanes, and sometimes a small percentage...

Firmus Co-CEO Oliver Curtis said: “AI is going to be one of the largest new sources of electricity demand Australia has ever seen.

Mahesh Reddy Indluri, Co-Chief Executive Officer, GreenPoint Energy, said the partnership between GreenPoint Energy and Centalion on Koolunga “highlights the importance of strategic long-term offtake structures for battery energy storage systems to support Australia’s data centre ambitions. This offtake structure positions Koolunga within a broader firm load supply model designed to specifically support large scale commercial customers with renewable energy,” he said.
