The Supernode battery project in Brisbane is undergoing a massive expansion, tripling in size following an extension agreement between Quinbrook Infrastructure Partners and Origin Energy. The project's first stage, currently under construction, is sized at 250 MW and 520 MWh. With the recent extension, the battery will now be a four-hour facility with a total capacity of 1560 MWh, making it one of the largest in Australia. Origin Energy's commitment to the project reflects its strategic shift towards flexible capacity and reliance on renewable energy sources. The company sees battery storage as essential for firming variable renewable energy supply and ensuring a secure and reliable energy grid. The Supernode battery will support Origin Energy's transition away from 'baseload' power generation, with plans to close the Eraring coal-fired generator and invest in various storage projects. The battery project is seen as crucial for Queensland's power system, with the site's proximity to the South Pine switchyard facilitating efficient energy flow. The Supernode battery will play a significant role in responding to market signals promptly, supporting grid stability, and participating in energy markets for revenue generation. As Australia aims to achieve 85% renewables by 2035, the expansion of battery storage capacity, including projects like the Supernode battery, will be instrumental. The project's ability to adapt to changing market dynamics and provide grid support functions highlights the growing importance of battery technology in the transition to green energy.
