May 13, 2025, Munich, Germany  - Hithium, a leading global new energy technology company, and Schoenergie, a German full-service provider of sustainable and affordable energy solutions, have achieved a major milestone with their first joint large-scale utility Battery Energy Storage System (BESS) project in Germany.

The project features a cutting-edge battery storage system (21MW / 55MWh) co-located with a 20MW solar park. With a direct connection to a substation, the system provides vital grid services such as frequency control, voltage regulation, and black start capability. Solar panels on top of the containers can power the storage’s cooling, improving sustainability. Most notably, this is one of the first real-world deployments of grid-forming technology in continental Europe, capable of reacting to grid frequency shifts in milliseconds. Hithium will supply 11 units of its 5MWh BESS containers to enhance grid stability and renewable energy integration, solidifying its commitment to Germany’s energy transition.

The partnership between Hithium and Schoenergie extends beyond their BESS project, with both parties already planning future initiatives to deepen their collaboration. In September 2024 and April 2025, Schoenergie’s team and their external experts visited Hithium’s headquarters in Xiamen, China, and successfully completed the factory acceptance test for the BESS units, ensuring the highest standards of quality, performance, and safety.

One Container, One Research Vision: SUREVIVE

The BESS containers are installed on a battery storage park fully developed by Schoenergie in its role as EPC and will be used in the German government-funded SUREVIVE research project. The project investigates how grid-forming inverters and batteries can stabilize the grid under real-world conditions in the EU power network. The system will support frequency regulation, provide instantaneous reserve power, and test black start capability—crucial for rebuilding the grid after large-scale outages. Findings from the project will inform regulatory guidelines and support broader deployment of grid-forming technology across Europe.

Volker Schöller, Chief Technology Officer of Schoenergie explains: “Modern battery systems must do more than store energy. They must respond to volatility, operate flexibly across multiple markets, be grid building and grid forming and support the grid by also delivering inertia. Our joint BESS project with Hithium demonstrates exactly these capabilities and paves the way for a truly renewable-based power infrastructure.”

“We are honored to partner with Schoenergie, combining our reliable and efficient BESS solution with Germany’s leadership in grid innovation,” added Min Yang, Senior Sales Director of Hithiun DACH. “This project not only addresses immediate grid stability challenges but also lays the foundation for a resilient and sustainable energy future in Europe. Together, we’re not just stabilising grids today—we’re building a blueprint for Europe’s resilient, sustainable energy future.”
