e-STORAGE Secures a Battery Energy Storage Project in Germany as Part of its European Expansion

KITCHENER, ON, Nov. 12, 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 signed a Battery Energy Storage System (BESS)  Supply Agreement for a 20.7 MW / 56 MWh DC energy storage project in Lower Saxony, Germany. The agreement also includes a 20-year Long-Term Service Agreement (“LTSA”).

By delivering bankable technology and lifecycle services, e-STORAGE supports the build-out of flexible grid infrastructure that enables renewable integration and system stability in key European markets.

e-STORAGE will supply and commission an integrated BESS solution based on its proprietary SolBank technology platform. Shipments are scheduled to begin in March 2026, with commissioning targeted for later that year. The LTSA will provide long-term maintenance and performance services to ensure operational reliability throughout the project’s lifespan.

The project was developed by Kyon Energy, which will also serve as the Engineering, Procurement, and Construction Management (EPC-M) contractor until commercial operation.

Florian Antwerpen, Managing Director of Kyon Energy, said, “Large-scale battery storage systems are a key component of Germany’s energy transition and security of supply. They provide the urgently needed flexibility in the power grid – more efficiently than any other technology. As one of the leading developers and operators of BESS in Germany, we are consistently driving forward the expansion of this infrastructure.”

Colin Parkin, President of e-STORAGE, said, “Strengthening grid flexibility is central to Europe’s energy transition, and bankable storage assets have an increasingly important role in that process. We are committed to supporting this need in Germany and across the region through responsible, long-term participation in the market.”
