KITCHENER, ON, Oct. 29, 2025 /PRNewswire/ — Canadian Solar Inc. (the “Company” or “Canadian Solar”) (NASDAQ: CSIQ) today announced that e-STORAGE, part of the Company’s majority-owned subsidiary CSI Solar Co., Ltd. (“CSI Solar”), has successfully achieved commercial operation of the 220 MWh DC Mannum Battery Energy Storage Project in South Australia. e-STORAGE served as the Engineering, Procurement, and Construction (EPC) provider for the project, which is owned by Epic Energy and was developed by Recurrent Energy, a subsidiary of Canadian Solar.
e-STORAGE has further strengthened its track record in delivering large-scale storage solutions by commissioning the project in Australia. This success was driven by e-STORAGE’s experienced local team and its partnership with Consolidated Power Projects (CPP) as the Balance of Plant contractor.
The project utilizes e-STORAGE’s proprietary SolBank technology, ensuring safe, reliable, and high-performance operation. Under a long-term service agreement, e-STORAGE will also support the project’s ongoing performance and operational management, demonstrating its commitment to long-term value creation.
Situated alongside 46 MWp of solar farm capacity also owned by Epic Energy at the Mannum site, the Mannum project marks a significant milestone in strengthening South Australia’s grid stability and will make a significant contribution to South Australia’s target of 100% renewable electricity generation by 2027.
Stephen Mudge, Interim Co-Chief Executive Officer of Epic Energy, said: “The commissioning of the Mannum grid-scale battery is an important milestone in our ongoing commitment to South Australia’s energy security, and we thank all our internal and external partners for successfully delivering this complex project.”
Colin Parkin, President of e-STORAGE, commented: “We are delighted to support Epic Energy in reinforcing South Australia’s grid resilience and accelerating the shift towards clean energy. Today, with over 1.8 GWh of BESS under construction in Australia, e-STORAGE continues to establish itself as a leading product and solution provider in the region.”
