Munich, May 28, 2026 – Kyon Energy continues to drive the expansion of large-scale battery storage systems in Germany. With the start of construction at the Brilon-Nehden (North Rhine-Westphalia), Sülzetal (Saxony-Anhalt), and Husum (Schleswig-Holstein) sites, the company is now implementing three more projects. Together, these facilities have a capacity of approximately 273 MW and a storage capacity of approximately 552 MWh.
These three large-scale battery storage systems mark another important step in building much-needed flexibility capacities for an increasingly renewable energy system. As a project developer, builder, and operator, Kyon Energy implements these facilities as a single-source provider, thereby strengthening its role as an Independent Flexibility Provider (IFP) in the German electricity market.
In Brilon-Nehden in the Hochsauerland district, a battery storage system with a capacity of approximately 103 MW and a storage capacity of approximately 208 MWh is being built. This project will help stabilize the power system in a region particularly strained on the grid side. By rapidly providing flexibility, the storage system can compensate for short-term fluctuations in the power grid, thereby strengthening local supply security.
At the Sülzetal site near Magdeburg, Kyon Energy is implementing a battery storage facility with a capacity of approximately 23.7 MW and a storage capacity of about 48 MWh. This project complements the company's storage portfolio in the East German grid area and helps strengthen regional grid stability and make electricity from renewable energies more efficiently usable.
With approximately 146.5 MW of power and around 296 MWh of storage capacity, the Husum project is one of the larger undertakings in Kyon Energy's current portfolio. In Schleswig-Holstein, a region with a very high proportion of wind energy, the storage system will be able to absorb generation peaks and feed electricity back into the grid as needed. This project thus helps to better utilize existing wind power potential and relieve the burden on the power system in a key energy transition region.
With all three projects, Kyon Energy creates additional flexibility in the power system – a central prerequisite for the success of the energy transition. Battery storage systems enable the efficient integration of fluctuating renewable energies, balance short-term grid imbalances, and thus ensure the stability of the overall system. The facilities therefore make a significant contribution to supply security while simultaneously reducing the need for fossil flexibility options. These projects are part of Kyon Energy's extensive project pipeline. The company develops, builds, and operates battery storage systems along the entire value chain and, with a project pipeline of more than 7 GW and over 1.2 GW under implementation, is one of the leading players in the German market.
“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,” says Thomas Maubert, Managing Director of Kyon Energy. “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 is a leading German project development company that focuses on large-scale battery storage systems and acts not only as a project developer but also as an EPCM (Engineering, Procurement, Construction, and Management) and operator of the facilities. As an Independent Flexibility Provider (IFP), the company, with more than 1.2 GW of projects under implementation, significantly contributes to stabilizing the German power system. With 269 MW of battery storage systems successfully developed and sold with partners, over 1.5 GW of approved and ready-to-build projects, and a current project pipeline of over 7 GW, Kyon Energy is one of the market leaders in Germany. The company, which was acquired by TotalEnergies in January 2024, has a particular focus on the development and optimization of multi-use strategies, combined with deep expertise in project development and management, as well as the regulation of large-scale battery storage systems. Through its battery storage systems, Kyon Energy is a driver of the energy transition and strives for a world powered by renewable, sustainable, and independent energy.
