Shining a Light on Germany's Renewable Energy Revolution: A Closer Look at its Largest Battery Storage Systems
Operational: Largest Battery Storage Facility in Germany, Situated in Schleswig-Holstein, Commences Service
Germany's transition towards a green energy future is gaining momentum with the launch of some impressive battery storage systems. The latest addition, situated in Bollingstedt, Schleswig-Holstein, is among the country's largest, storing excess wind and solar energy to provide renewable energy for up to 170,000 households during peak demand times.
The system, developed by Eco Stor and EPW GmbH, has a 103.5 megawatt (MW) capacity and a storage capacity of 238 megawatt-hours (MWh). Consisting of 64 containers stuffed with lithium-ion batteries and 32 containers for inverters and transformers, it's a testament to Germany's commitment to reducing reliance on fossil fuels and stabilizing power grids.
According to Tobias Goldschmidt, Schleswig-Holstein's Minister of Energy, battery storage systems are multitaskers that smooth out natural fluctuations in solar and wind energy, stabilize grids, lower electricity prices, and increase the share of green power in grids. Eco-Stor CEO, Georg Gallmetzer, is excited about the potential of these systems, suggesting they can shift valuable solar power into the evening hours, smooth out prices, and further reduce power from gas and coal.
A closer look at the German battery storage landscape reveals several upcoming and recently completed large-scale projects. One such project is Eco Stor's Bollingstedt and Schuby projects, the latter being situated just 5 km away. The Bollingstedt project, which is the largest in the country, boasts a capacity of 103.5 MW/238 MWh. In Schuby, an identical project is under construction.
Eco Stor is leading the charge in the development of larger systems, with several planned, each promising a capacity of 300 MW/600 MWh. Additionally, a project in Tantow by Green Flexibility and Enertrag is set to have a power capacity of 60 MW and a storage capacity of 130 MWh, with commissioning slated for early 2026.
Another notable project is the co-located 21 MW/55 MWh battery storage system by HiTHIUM and Schoenergie with a 20 MW solar park. These developments underscore the growth and investment in battery storage systems in Germany, aiming to enhance grid stability and integrate renewable energy sources more effectively.

- The development of large-scale battery storage systems in Germany, such as Eco Stor's projects in Bollingstedt and Schuby, is contributing to the environmental-science and technology sector, offering vocational training opportunities for community members in the renewable energy industry.
- The investment in battery storage systems, like the one in Tantow by Green Flexibility and Enertrag, not only ensures grid stability but also offers potential financial benefits, such as lower electricity prices and savings in energy costs, especially with excess wind and solar energy storage.
- As Germany continues to prioritize renewable energy and battery storage solutions, partnerships between companies like HiTHIUM and Schoenergie, and their joint endeavor to create a co-located battery system, demonstrate the growing importance of these technologies in the science, energy, and technology sectors, with a focus on environmental sustainability.
