Australia’s renewable energy landscape just gained a powerful boost. Octopus Australia, a subsidiary of Octopus Energy, has announced the acquisition of the Coleambally Battery Energy Storage System (BESS) from Risen Energy—marking another strategic leap in the nation’s clean energy transformation. This move not only expands Octopus’s growing portfolio but also accelerates the journey toward a flexible, sustainable, and resilient energy future for New South Wales and beyond.

The acquisition of the Coleambally BESS project represents a significant milestone for Octopus Australia’s renewable expansion. Situated in the Murrumbidgee region of southern New South Wales, the 100 MW/400 MWh battery project is designed to strengthen grid stability and support peak demand across the region. With both development and grid connection approvals already secured, Octopus is now taking the reins to guide the project through its final development, procurement, and financing stages. This move builds on the company’s billion-dollar partnership with Dutch pension investor APG—an alliance aimed at accelerating Australia’s clean energy pipeline and addressing the country’s growing demand for renewable infrastructure.

By integrating battery storage with renewable generation, the Coleambally project is set to redefine how energy is produced and consumed. The battery will operate in synergy with the Darlington Point Solar Farm, one of the largest in the country, creating a balanced ecosystem that can store excess solar power during the day and release it when evening demand peaks. The installation of approximately 1,440 meters of underground 330 kV high-voltage cable connecting the BESS substation to the existing Darlington Point substation further underscores the project’s advanced engineering and readiness. This approach not only enhances grid reliability but also aligns seamlessly with New South Wales’ ambitious 2 GW energy storage target by 2030.

Once operational, the Coleambally Battery will trade its stored energy in the merchant market, ensuring reliable electricity supply during critical demand periods. This model of flexible energy trading reflects Octopus’s vision of building a dynamic, technology-driven grid that adapts to real-time needs. More importantly, it demonstrates how renewable assets can evolve beyond generation—providing dispatchable energy that directly supports both consumers and the national grid. As Octopus Australia continues to lead in sustainable innovation, the Coleambally project stands as a beacon for what’s next in the renewable energy transition: smarter storage, stronger systems, and a cleaner future powered by purpose.
