Canadian Solar’s e-STORAGE Signs 20.7 MW / 56 MWh Battery Storage Agreement In Lower Saxony, Germany, With 20-Year Service Support

Canadian Solar Inc. has announced that e-STORAGE, part of its majority-owned subsidiary CSI Solar Co., Ltd., 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), ensuring ongoing maintenance and performance support throughout the project’s lifespan. The project, developed by Kyon Energy, will be executed with Kyon serving as the Engineering, Procurement, and Construction Management (EPC-M) contractor until commercial operation.

e-STORAGE will provide and commission an integrated BESS solution built on its proprietary SolBank technology platform. Shipments are scheduled to begin in March 2026, with commissioning expected later in the year. The LTSA ensures operational reliability and long-term performance of the system. By delivering bankable technology and lifecycle services, e-STORAGE aims to support the development of flexible grid infrastructure that enables renewable energy integration and enhances system stability in key European markets.

Large-scale battery storage systems are becoming increasingly essential to Germany’s energy transition, providing critical grid flexibility more efficiently than other technologies. Florian Antwerpen, Managing Director of Kyon Energy, emphasized that large-scale battery storage is a vital component of Germany’s energy transition and supply security. He highlighted that these systems offer the flexibility needed for a stable power grid and that Kyon Energy is actively advancing the expansion of this infrastructure.

Colin Parkin, President of e-STORAGE, noted that strengthening grid flexibility is central to Europe’s renewable energy transition. He added that bankable storage assets play a key role in supporting the region’s energy needs and reaffirmed e-STORAGE’s commitment to responsible, long-term participation in Germany’s energy storage market. This project underscores Canadian Solar’s commitment, through e-STORAGE, to advancing energy storage solutions that support the growth of renewable energy and the stability of power grids across Europe.
