HyperStrong has marked a major milestone in its European expansion with the groundbreaking of the 1.6 GWh Boxberg 400 GigaBattery project in Saxony, Germany, the company acting as turnkey contractor for the BESS for the flagship utility‑scale storage installation, working alongside project owner LEAG Clean Power and other partners.
Built on the six‑hectare remediated site of the former “Plant II” at the Boxberg power plant location, the project features 400 MW of grid‑connection capacity and 1,600 MWh (1.6 GWh) of storage capacity. Upon completion, the facility can theoretically supply electricity to approximately 640,000 households for four hours, setting new industry benchmarks for grid stabilisation and efficient utilisation of variable renewable power.
The scope of HyperStrong’s involvement is the end‑to‑end delivery of the battery energy‑storage system, including the supply of battery systems equipped with lithium‑iron‑phosphate cells, the integration of electrical equipment and the turnkey construction of the storage facility. The project will deploy the company’s field‑proven HyperBlock III liquid‑cooled utility‑scale storage system.
Senior VP Pingyang Wang commented: “We are delighted to stand alongside LEAG today to break ground on the Boxberg 400 GigaBattery project. This 1.6 GWh facility embodies HyperStrong’s unwavering dedication to Germany’s energy transition. By deploying our mature BESS solution and comprehensive EPC capabilities, we look forward to seeing this site become one of Europe’s largest battery storage facilities, delivering reliable and flexible power to support Germany’s renewable ambitions over the long term.”
The project further strengthens HyperStrong’s local presence in Germany and demonstrates its ability to deliver large-scale energy storage projects across Europe.
LEAG Clean Power emphasised the strategic value the project brings to Germany’s energy transition and regional development, its CEO Thomas Brandenburg adding: “The energy supply of the future requires high‑performance storage systems. At LEAG Clean Power, we are establishing another key component in Boxberg for the integration of renewable energies and the security of supply in Germany. The Boxberg 400 marks another milestone in the development of our GigawattFactory. It will help make wind and solar power flexibly usable and strengthen the stability of the electricity grid. At the same time, the project makes a crucial contribution to the transformation of the Lusatia energy region. Together with HyperStrong and other partners, we are launching a pioneering infrastructure project here that provides concrete support for the energy transition.”
