An energy storage facility with a capacity of 40 MWh is being built in northern Germany.
German Company Kyon Energy Begins Construction of 40 MWh Battery Energy Storage System
German company Kyon Energy has announced the start of construction on a new battery energy storage system with a capacity of 40 MWh in the town of Großenwiehe, located near the Schobüll transmission station in northern Germany.
The Strategic Role of Energy Storage
The planned installation, with a power output of 20 MW and a capacity of 40 MWh, is part of the dynamic development of battery technology in Germany. Energy storage systems like the one in Großenwiehe are crucial for storing surplus energy generated by wind and solar farms and feeding it back into the grid during times of increased demand. In doing so, they support balancing and wholesale markets, contributing to greater supply security and flexibility in the power system.
“Energy storage systems compensate for fluctuations in the grid in real time, preventing overloads and ensuring reliable, socially responsible electricity supply,” emphasizes Florian Antwerpen, Managing Director of Kyon Energy.
Local Support and Grid Integration
The Großenwiehe project has received support from local authorities. Mayor Keno Jaspers expressed satisfaction with the investment, noting that it aligns with the strategy for energy independence and active community participation in the energy transition.
The battery will be integrated into the distribution grid, enabling effective balancing of energy fluctuations and maximizing the use of renewable sources. This is further proof that storage technologies are an essential element of modern energy infrastructure.
Kyon Energy – A Driving Force of the Energy Transition
Based in Munich, Kyon Energy specializes in the design, construction, and—recently—operation of large-scale grid-connected energy storage systems. The company was acquired in early 2024 by French energy giant TotalEnergies, significantly strengthening its position in the German market. Thanks to its new business model, Kyon is becoming a comprehensive provider of flexibility in the energy sector.
Currently, the company has over 1 GW of approved projects ready for implementation and a total project pipeline of over 7 GW. So far, Kyon has successfully developed and sold 121 MW of battery systems, with the ambition to launch more storage capacity than is currently operating on the German market.
Among upcoming projects is a 102 MW / 204 MWh installation in Brilon (North Rhine-Westphalia), set to begin construction in summer 2025. Meanwhile, Kyon’s first directly operated system will be a 100 MW / 200 MWh battery in Dahlem, valued at over €75 million.
No Green Future Without Storage
According to 2022 data, due to insufficient storage capacity and infrastructure limitations, the German power system was forced to curtail nearly 4.5% of renewable energy production. This corresponds to 8.07 TWh of unused energy—enough to power nearly 2.9 million households for a year.
“The current grid infrastructure is not suited to the variability of renewable energy production. With our energy storage systems, we can balance these fluctuations and accommodate more clean energy into the grid,” Kyon Energy stated in an official release.
