Canadian Solar Inc. announced that its energy storage subsidiary, e-STORAGE, has successfully achieved commercial operation of the 220 MWh DC Mannum Battery Energy Storage Project in South Australia. The project, owned by Epic Energy and developed by Recurrent Energy—a subsidiary of Canadian Solar—marks a major milestone in advancing grid stability and renewable energy integration in the region. e-STORAGE served as the Engineering, Procurement, and Construction (EPC) provider, underscoring its expertise in delivering large-scale, high-performance battery energy storage solutions.
The successful commissioning of the Mannum project reflects e-STORAGE’s strong technical capabilities and growing footprint in Australia’s renewable energy market. The project’s delivery was made possible through the collaboration of e-STORAGE’s experienced local team and Consolidated Power Projects (CPP), which acted as the Balance of Plant contractor. This partnership highlights the company’s ability to combine global technology leadership with local execution strength.
At the core of the Mannum Battery Energy Storage Project is e-STORAGE’s proprietary SolBank technology, designed to ensure safe, reliable, and efficient operation throughout the system’s lifecycle. In addition to the project’s development and commissioning, e-STORAGE has entered into a long-term service agreement to manage ongoing operations and maintenance. This approach ensures consistent performance, reliability, and value creation over time, reinforcing e-STORAGE’s commitment to sustainable, long-term partnerships with asset owners.
The Mannum project is strategically located alongside 46 MWp of solar farm capacity, also owned by Epic Energy, creating a hybrid renewable setup that enhances system efficiency and grid flexibility. By storing excess solar energy and releasing it during peak demand periods, the battery system supports the reliability of South Australia’s power grid. Importantly, the project contributes to the state’s ambitious target of achieving 100% renewable electricity generation by 2027, positioning it as a key component of Australia’s clean energy transition.
Stephen Mudge, Interim Co-Chief Executive Officer of Epic Energy, emphasized the significance of the achievement, noting that the commissioning of the Mannum grid-scale battery represents a critical step in advancing South Australia’s energy security. He expressed gratitude to both internal and external partners for their collaboration in bringing this complex project to fruition.
Colin Parkin, President of e-STORAGE, also highlighted the importance of the project for the company’s regional strategy. He stated that e-STORAGE is proud to support Epic Energy in strengthening South Australia’s grid resilience and accelerating the shift toward renewable power. With more than 1.8 GWh of Battery Energy Storage Systems (BESS) currently under construction across Australia, e-STORAGE continues to solidify its reputation as a leading provider of advanced energy storage products and solutions.
The successful completion of the Mannum Battery Energy Storage Project not only enhances South Australia’s renewable infrastructure but also demonstrates Canadian Solar’s growing influence in the global energy storage sector. Through e-STORAGE and its innovative technologies, Canadian Solar remains at the forefront of enabling the transition toward cleaner, more resilient, and sustainable energy systems worldwide.
