Supernode BESS

The Supernode Battery Energy Storage System (BESS), located adjacent to the South Pine switchyard in Brendale, Queensland, is one of Australia’s largest battery storage campuses.

Strategically positioned at the central node of Queensland’s electricity transmission network, Supernode provides large-scale energy storage, flexibility and grid support while enabling the continued integration of renewable energy across the state.

Stages 1 and 2 are now operational with a combined capacity of 520 MW / 1,858 MWh, making them the largest operational BESS in Australia’s National Electricity Market. Combined with Stage 3, Supernode will provide approximately 780 MW / 3,073 MWh of battery storage capacity.

Grid and Energy Benefits

• Provides large-scale energy storage, flexibility and firming to Queensland’s electricity grid.
• Supports the integration of renewable energy by storing electricity during periods of high generation and making it available during periods of higher demand.
• Helps strengthen grid stability and reliability as Queensland’s electricity system transitions towards increasing levels of renewable generation.
• Strategically located at the heart of Queensland’s transmission network, supporting efficient energy delivery and grid access.
• Once the first three stages are operational, Supernode is expected to support the equivalent power needs of approximately 188,000 typical Queensland households during evening peak periods.

Project Status

Supernode BESS is being delivered in multiple stages as part of the wider Supernode energy and digital infrastructure precinct.

• Stage 1 – 260 MW / 619 MWh: Commenced commercial operations in February 2026.
• Stage 2: Commenced commercial operations in July 2026. Together, Stages 1 and 2 provide 520 MW / 1,858 MWh of operational capacity.
• Origin Energy has contracted 100% of the capacity of Stages 1 and 2 under 12-year tolling agreements.
• Stage 3: Contracted under a 15-year offtake agreement with Stanwell Corporation and progressing towards completion.
• Investment across Stages 1, 2 and 3 is expected to exceed A$1.4 billion.
• Further expansion is planned,

Grid Connection and Operations

Supernode BESS is strategically located adjacent to the South Pine switchyard at the heart of Queensland’s electricity transmission network, providing direct access to critical high-voltage transmission infrastructure.

This strategic location enables Supernode to provide grid stability, flexibility and firming services while supporting the optimisation and integration of renewable energy generation across Queensland.

Supernode is being delivered in partnership with Quinbrook affiliate Private Energy Partners, which has supported the design, procurement and construction of the project and will oversee longer-term asset management.
