The second stage of the Supernode battery energy storage system (BESS), has commenced operations this week, bringing the total nameplate capacity to 520 megawatts (MW) and 1,858 megawatt-hours (MWh), making it the biggest in the main grid at the moment.
The Supernode project is being developed by global investment giant Quinbrook and actually refers to two separate projects – the Supernode BESS which will eventually boast 760 MW/3096 MWh of storage, as well as the adjacent Supernode Data Centre (Supernode DC).
The battery project could be expanded further, to 1GW and 5,000 MWh, depending on future demand, which would make it the biggest battery in Australia.
The first two stages are now operating under a long-term tolling agreement with energy giant Origin Energy. The third and final stage, which has been contracted by Stanwell Corp under a 15-year off-take agreement, also reached financial close this week on a $469 million debt financing package.
“Achieving commercial operations for Stage 2 means we’ve successfully delivered both Origin contracted stages on schedule, an outcome we’re incredibly proud of given the complexity of commissioning utility-scale battery storage projects in Australia,” said Tim Horneman, managing director and regional leader for Australia at Quinbrook.
