HyperStrong International, which is based in Germany, is a subsidiary of Beijing HyperStrong Technology Co. With LEAG Clean Power GmbH it has signed an engineering, procurement and construction contract to deploy a 1.6 GWh utility-scale battery energy storage system project in Germany. Once completed, this project will be one of the largest battery storage facilities in Europe.
The new project ‘GigaBattery Boxberg 400’ will form part of LEAG’s GigawattFactory concept – an integrated renewable energy hub combining photovoltaic and wind generation with flexible storage and hydrogen-ready power plants.
The Boxberg project will adopt HyperStrong’s 4-hour energy storage system, based on its HyperBlock III product. This is a well-established, field-verified utility-scale storage product designed for stable operation under diverse climatic conditions. The system combines liquid cooling technology, intelligent energy management, and excellent safety performance, so well suited to grid-scale applications in Europe’s variable energy environment. Once operational, the system can provide critical grid services, support renewable integration, and enhance energy security for the region.
HyperStrong has extensive project experience across utility-scale and commercial/industrial applications and deployed over 45 GWh of energy storage systems worldwide across more than 400 projects.
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.
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.
