Supernode Stage 2 Completes Construction and Commences Operations

Stages 1 and 2 are now the largest operational BESS in Australia’s National Electricity Market

Brisbane – 28 July 2026  – Quinbrook, a specialist investment manager focused exclusively on delivering the infrastructure needed for the energy and digital transitions, today announced that Stage 2 of its Supernode battery storage project in Queensland has successfully completed construction and commenced commercial operations. Moreover, Stage 3 has also reached financial close on an additional A$469 million in debt financing, bringing total project financing across the Supernode complex to c. A$1.2 billion.

The first two stages of Supernode are now operational which completes delivery of the Origin-contracted stages marking another successful milestone in the project’s development.

Stage 2 is now operating under a long-term tolling agreement with Origin Energy. Stages 1 and 2 have a combined capacity of 520 MW / 1,858 MWh. The first two stages were delivered in line with the original completion schedule despite the many complexities of constructing and commissioning utility-scale battery storage systems in Australia’s National Electricity Market (‘NEM’). Stages 1 and 2 together comprise the largest operating BESS in the NEM today.

Supernode Stages 1 and 2 were delivered in partnership with Quinbrook affiliate Private Energy Partners, with the partnership continuing through construction of Stage 3.

Stage 3 also reached financial close on a A$469 million debt financing package. The financing builds on the January 2025 financing of Stages 1 and 2 with continued backing from Commonwealth Bank of Australia, MUFG and Deutsche Bank, alongside new lending partners DNB and Rabobank. Financing terms improved on the earlier facilities, reflecting Quinbrook’s growing track record in developing, constructing and financing utility-scale battery storage coupled with the strength of Stage 3’s 15-year offtake agreement with Stanwell Corporation.
