HyperStrong International (Germany) GmbH, a subsidiary of Beijing HyperStrong Technology Co., Ltd. has signed an EPC contract with LEAG Clean Power GmbH to develop a 1.6 GWh utility-scale battery energy storage system (BESS) in Germany. Once completed, the project will stand among the largest battery storage facilities in Europe, marking a major milestone in the region’s clean energy expansion.
Named GigaBattery Boxberg 400, the project forms a key part of LEAG’s GigawattFactory initiative, an integrated renewable energy hub that combines solar, wind, flexible storage, and hydrogen-ready power plants. This collaboration reinforces LEAG’s commitment to delivering a reliable, sustainable, and secure energy supply for Germany’s future.
The Boxberg system will utilize HyperStrong’s 4-hour energy storage solution, built on its proven HyperBlock III technology, a field-tested, utility-scale product engineered for stable operation in diverse climates. Featuring liquid cooling, intelligent energy management, and advanced safety architecture, the system is optimized for grid-scale performance in Europe’s dynamic energy landscape. Once operational, it will deliver essential grid services, facilitate renewable integration, and strengthen regional energy security.
“With this project, we continue to accelerate our GigawattFactory strategy and expand the foundation for a carbon-neutral energy system,” said Adi Roesch, CEO of LEAG Group. “Battery energy storage plays a crucial role in balancing renewable fluctuations and ensuring energy remains available when it is needed. Working with a technology-driven partner like HyperStrong enables us to deliver on this vision efficiently and at scale.”
HyperStrong, with the EMEA regional headquarter in Frankfurt, Germany, is a Tier-1 global energy storage solution provider with extensive project experience across utility-scale and commercial & industrial applications. The company has deployed over 45 GWh of energy storage systems worldwide across more than 400 projects – offering high efficiency, safety, and reliability for BESS applications.
For this project, HyperStrong will serve as the EPC contractor, delivering a turnkey, full-station energy storage solution that covers engineering design, equipment supply, system integration, commissioning, grid connection, and long-term operation support.
“We are honored to partner with LEAG Clean Power on this landmark 1.6 GWh project, which demonstrates both companies’ shared commitment to building a resilient, low-carbon energy future,” said Dr. Jianhui Zhang, Chairman and CEO of HyperStrong. “This collaboration represents not only a milestone for our global strategy, but also a significant contribution to Germany’s and Europe’s renewable energy transition. Together, we are unlocking the potential of energy storage to power the next era of clean energy.”
The cooperation between HyperStrong and LEAG Clean Power is part of a broader effort to expand large-scale energy storage capacity in Germany. The German government has reaffirmed the strategic importance of storage systems for achieving a secure, affordable, and sustainable electricity system.
“This partnership brings together complementary strengths – the energy expertise of LEAG Clean Power and HyperStrong’s approach to ensure high technical availability and efficiency,” said Thomas Brandenburg, CEO of LEAG Clean Power GmbH. “The project will set a new milestone for battery storage deployment in Europe and demonstrates the growing importance of global collaboration in achieving energy transition goals.”
Mr. Pingyang Wang, Senior Vice President of HyperStrong International and President of EMEA Region, added, “We are truly honored that LEAG Clean Power has selected HyperStrong as their partner for the Boxberg project. This trust inspires us to bring our full expertise and commitment to deliver a project of the highest quality, while strengthening our long-term presence in Germany and supporting the energy transition across Europe.”
