Kyon Energy , Germany's leading developer of large-scale energy battery storage systems (BESS), EPCM (engineering, procurement, construction, and management) provider, and operator of large-scale battery storage facilities, is working with battery technology specialist Saft , a subsidiary of TotalEnergies, in Dahlem, North Rhine-Westphalia, to build one of Germany's most significant battery storage facilities. With an output of 100 megawatts (MW) and a storage capacity of 203 megawatt hours (MWh), the large-scale storage facility in Dahlem will be one of the largest of its kind.
The plant will play a key role in stabilizing and increasing the flexibility of the German power grid. It is scheduled to begin commercial operation in October 2026.
Progress in record time Construction work on the Dahlem storage project is progressing rapidly. The delivery and installation of 70 battery containers and 35 MVPS (medium voltage power station) containers was completed in October 2025 in just 18 working days, setting a new record.
Electrical installation work began in November 2025 and will take several months to complete. The switchgear and plant control systems buildings will be constructed in stages. The empty conduits for the 110 kV underground cable route have already been laid for the new, purpose-built 110 kV substation, as have the foundations for the two high-voltage transformers. The transformers are due to arrive at the end of 2025, allowing the physical grid connection to be completed in the first quarter of 2026, with the plant being powered up in the second quarter.
Technology partnership strengthens innovative storage solutions The Dahlem project relies on energy-efficient, durable and safe high-performance battery containers from the French manufacturer Saft. Specifically, it uses the Intensium® Shift+. These systems use modern lithium-ion technology with lithium iron phosphate (LFP) cells and are specially designed for large-scale energy storage.
As subsidiaries of TotalEnergies, Saft and Kyon Energy are playing a pivotal role in the global energy transition. Together, they are developing sustainable energy storage solutions to enable the shift towards a low-carbon energy system.
