HiTHIUM, a global energy technology leader, and Schoenergie, a German clean energy provider, have announced the launch of their first joint large-scale utility Battery Energy Storage System (BESS) project in Germany. The milestone project—21 MW / 55 MWh in capacity—is co-located with a 20 MW solar park and connected directly to a substation, enabling critical grid services such as frequency control, voltage regulation, and black start capability.
Notably, this marks one of continental Europe’s first real-world deployments of grid-forming battery technology. The system uses 11 of HiTHIUM’s 5 MWh BESS containers, designed to respond to frequency shifts within milliseconds. Solar panels atop the containers power their cooling systems, enhancing overall sustainability.
This project plays a central role in the German government-funded SUREVIVE research initiative. The goal is to assess how grid-forming inverters and storage systems can maintain grid stability under real-world European power network conditions. Findings will guide future regulatory frameworks and support broader adoption of grid-forming solutions.
Schoenergie, acting as EPC, oversaw full development of the storage park. Factory acceptance tests were conducted in Xiamen, China, where both companies’ teams gathered to ensure top-tier safety and performance standards.
“Modern batteries must provide flexibility, stability, and inertia to support a renewable grid,” said Volker Schöller, CTO of Schoenergie. HiTHIUM’s Min Yang emphasized, “This collaboration not only stabilizes the grid today but sets a blueprint for Europe’s sustainable energy future.”
