November 24, 2025: China’s HyperStrong International and LEAG Clean Power have signed an EPC (engineering, procurement and construction) contract to deploy a 1.6GWh utility-scale battery energy storage system project in Germany. Once completed, this project will become 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 four-hour energy storage system, based on its HyperBlock III product. HyperBlock III is a field-verified utility-scale storage product designed for stable operation under diverse climatic conditions. The system combines liquid cooling technology, and intelligent energy management.

Once operational, the system will provide critical grid services, support renewable integration, and enhance energy security for the region.

HyperStrong, a subsidiary of Beijing-based HyperStrong Technology with its EMEA regional headquarters in Frankfurt, Germany, is a Tier-1 global energy storage provider of utility-scale and commercial and industrial applications. The company has deployed over 45GWh of energy storage systems worldwide across more than 400 projects.

HyperStrong will be 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.

“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.”
