Supernode battery reaches 520 MW milestone, Stage 3 financed

⚡ AI Executive Summary

Quinbrook Infrastructure Partners has brought Stage 2 of its Supernode battery storage project in Queensland into commercial operation, expanding the facility to 520 MW / 1,858 MWh total capacity. The company has simultaneously secured financing for Stage 3, which will push capacity to 780 MW by 2027, with an additional Stage 4 under consideration. Supernode's strategic location at Queensland's central transmission node positions it as a critical asset for grid stability and renewable integration. The project demonstrates growing financial confidence in utility-scale battery storage as essential infrastructure for managing renewable energy variability. With staged expansion and multiple long-term offtake agreements in place, Supernode exemplifies how large-scale storage deployments can be financed and developed as backbone assets rather than marginal resources. This progression is significant for understanding how storage transitions from niche applications to core grid infrastructure in high-renewable penetration regions.
