Kyon Energy Simultaneously Breaks Ground on Large-Scale Battery Storage Projects in NRW, Saxony-Anhalt and Schleswig-Holstein

Munich – Kyon Energy is simultaneously commencing construction of three utility-scale battery storage systems at the sites of Brilon-Nehden, Sülzetal and Husum. The projects combine for approximately 273 MW of capacity and around 552 MWh of storage capacity, and are specifically designed to contribute to grid stability across three distinct grid regions.

With this triple groundbreaking, Kyon Energy is consistently executing its growth strategy as an Independent Flexibility Provider (IFP). The TotalEnergies subsidiary develops, builds and operates the systems in-house, and reports a project pipeline of more than 7 GW as well as 1.2 GW currently under development – making it one of the leading battery storage project developers in Germany.

Three Sites, Three Grid Regions, Varying Scales

The largest of the three projects is being built in Husum, Schleswig-Holstein: with approximately 146.5 MW of capacity and around 296 MWh of storage capacity, it is designed to absorb wind energy generation peaks in one of Germany's most wind-intensive regions. In Brilon-Nehden in the Hochsauerlandkreis – a region under particularly heavy grid stress – a storage system with approximately 103 MW and around 208 MWh is being built. The smallest addition is the storage facility in Sülzetal near Magdeburg, at approximately 23.7 MW and around 48 MWh, which expands Kyon Energy's portfolio in the eastern German grid area.

Growth Strategy With a Focus on Grid Bottlenecks and Security of Supply

With these three projects, Kyon Energy is deliberately positioning itself in regions where grid congestion and grid intervention costs (redispatch costs) are particularly significant. Managing Director Thomas Maubert states: "With the start of construction in Brilon-Nehden, Sülzetal, and Husum, we are implementing three more powerful large-scale battery storage systems and creating additional flexibility exactly where it will be urgently needed in the future. We are thus consistently pursuing our growth strategy and driving the development of a storage infrastructure that is indispensable for a renewable, flexible, and stable energy system."

Kyon Energy was acquired by TotalEnergies in January 2024. According to the company, it has to date successfully developed and divested 269 MW of battery storage and holds 1.5 GW of permitted and construction-ready projects.
