The new project will form part of LEAG’s GigawattFactory concept.
The project is a core component of LEAG’s GigawattFactory initiative, which integrates large-scale solar and wind generation with flexible battery storage and hydrogen-capable power infrastructure at the Boxberg site.
The storage system will utilise HyperStrong’s HyperBlock III product, a four-hour-duration solution incorporating liquid-cooling technology, advanced energy management systems, and comprehensive safety features. The design has been extensively tested in various operating environments and is optimised for grid-support applications across Europe’s diverse climate zones. Once commissioned, it will deliver essential frequency regulation, renewable energy integration, and system stability services.
HyperStrong will act as the turnkey EPC contractor, responsible for full-system design, equipment supply, grid connection, integration, commissioning, and ongoing operational support.
The company has delivered over 45 GWh of energy storage capacity through more than 400 projects worldwide, spanning utility-scale, commercial, and industrial segments.
The partnership between HyperStrong International and LEAG Clean Power supports Germany’s ongoing expansion of large-scale storage infrastructure. The German Government continues to emphasise the central role of battery systems in maintaining a reliable, cost-effective, and sustainable electricity supply as renewable generation increases.
Construction preparations for GigaBattery Boxberg 400 are now under way, with the project expected to contribute significantly to regional grid flexibility and the continued growth of renewable energy deployment in eastern Germany.
