Chinese energy storage company HiTHIUM and German sustainable energy service provider Schoenergie have announced the official launch of their first large-scale utility-grade energy storage project in Bavaria, Germany.
The project deploys a 21MW/55MWh energy storage system that coordinates with a neighboring 20MW solar plant, connecting directly to the grid through a substation to provide frequency regulation, voltage support, and black start capabilities.
Notably featuring grid-forming technology - among the first large-scale applications of this technology in continental Europe - the system utilizes inverters to actively construct grid voltage and frequency, replacing traditional synchronous generators with claimed millisecond-level dynamic response. The system comprises 11 HiTHIUM-supplied 5MWh containerized units integrated with rooftop PV panels to power cooling systems, reducing energy consumption.
The partners completed two rounds of equipment testing in September 2024 and April 2025. Schoenergie's technical team conducted factory acceptance tests in Xiamen, including extreme temperature performance verification and black start simulations.
The project is part of the German government-funded SUREVIVE research initiative, which aims to validate grid-forming technology's coordination with battery storage in real-world operations, potentially influencing future EU grid technical standards.
As EPC contractor, Schoenergie has implemented over 5,000 renewable energy projects globally since 2008, totaling 1,600MWp. HiTHIUM ranked third globally with 35.1GWh energy storage battery shipments in 2024, deriving 28.6% of its revenue from overseas markets.
