Quinbrook Infrastructure Partners, a global investment manager, announced the financial closure and commencement of construction for the first stage of the 'Supernode' Battery energy storage project. The project's first phase comprises a 250MW/2hr Battery Energy Storage System (BESS) and a data center facility in Queensland. 

The total capacity of the project is around 2000 MW; once operational, it will be one of the largest battery storage projects in Australia. Origin Energy has committed to the full capacity of stage one under a long-term offtake contract.

The 'Supernode' project is part of a USD 2.5 billion battery and data center integrated facility in south-east Queensland. The first stage of the project alone represents an investment by Quinbrook of over USD 325 million. The project is being developed on a 30-hectare site in the northern Brisbane suburb of Brendale.

The site has three direct connections into Queensland’s high-voltage transmission grid, two dedicated for battery storage, and the third for BESS and data centers in Australia. The Origin offtake agreement represents one of the largest binding BESS offtakes on a MW basis signed to date in Australia between two non-government parties. 

When operational, the Supernode BESS will enable the efficient storage of surplus solar and wind energy, aid the displacement of coal and other emissions-intensive generation sources and provide grid-support at the central node of the Queensland high voltage transmission network.

Objectives of Supernode BESS Project

Quinbrook Infrastructure Partners is leading the Supernode Battery Energy Storage System (BESS) project, which is a ground-breaking effort in the field of renewable energy. This ambitious project aims to address several key objectives, each contributing to a more sustainable and reliable energy future.

Efficient Energy Storage

One of the primary objectives of the Supernode BESS project is to enable the efficient storage of surplus solar and wind energy. This is a critical aspect of renewable energy utilization, as the intermittent nature of these sources necessitates a robust and reliable storage solution. By effectively storing surplus energy, the project ensures that the power generated does not go to waste and can be used during periods of high demand or low production.

Displacement of Emissions-Intensive Sources

The project also aims to aid the displacement of coal and other emissions-intensive generation sources. This is a significant step towards reducing the environmental impact of energy production. By promoting the use of renewable energy sources and providing a viable alternative to traditional fossil fuels, the Supernode BESS project contributes to global efforts to combat climate change.

Grid Support

Another key objective of the BESS project is to provide grid-support at the central node of the Queensland high voltage transmission network. This involves ensuring the stability and reliability of the power grid, which is crucial for maintaining consistent energy supply to homes and businesses. By providing this support, the project plays a vital role in the overall functioning of the energy infrastructure.

Stability

The project directly addresses stability issues facing the Queensland power grid, which have arisen due to record levels of rooftop solar installation across Queensland. These installations, while beneficial for harnessing solar energy, can pose challenges to the grid's stability. The Supernode BESS project aims to mitigate these challenges and ensure the continued reliability of the power supply.
