Schoenergie in Germany Has Commissioned A 21MW/55MWh Energy Storage Project

 

Schoenergie in Germany has commissioned a 21MW/55MWh energy storage project, marking the first use of grid-connected inverter technology in continental Europe's distribution network.

 

A large-scale grid-connected energy storage system, named SUREVIVE, has officially commenced operations in Flühlen, Saarburg County, Trier, Germany. The project, with a 21MW energy storage capacity and 55MWh, utilizes grid-connected inverter technology and shares a substation connection point with a 20MW ground-mounted photovoltaic power plant. It features black start capability and millisecond-level frequency response.

 

Developed by Schoenergie, the system is the first large-scale battery energy storage project to utilize grid-connected inverter technology in continental Europe's distribution network. The project, jointly developed by Westnetz, the Fraunhofer Institute for Solar Energy Systems, and the University of Stuttgart, also serves as a real-world research platform for distribution networks. The project focuses on verifying the technical performance of energy storage systems and grid-connected inverters in synergistic support for grid stability.

 

Katrin Eder, Minister of Energy and Climate Protection in the state of Rhineland-Palatinate, noted at the commissioning ceremony that the state's installed photovoltaic capacity has more than doubled from 2,302 MW in 2019 to 5,102 MW in 2024. As solar power continues to expand, supporting energy storage systems have become critical infrastructure for ensuring the economic integration of photovoltaic power. By the end of August 2025, the state had put 124,000 battery energy storage systems into operation, totaling 830 MW and providing over 1,200 MWh of usable storage capacity.
