- Europe's largest large-scale battery storage facility to date approved in Alfeld (Leine), Lower Saxony.
- The project will provide 137.5 megawatts of storage power and 275 megawatt hours of storage capacity for the German electricity grid.
- Realization of the storage project is planned by the end of 2025.
Munich, 13.11.2023. Kyon Energy, a leading project development company for large-scale battery storage systems, has received approval for a new large-scale battery storage project in Alfeld (Leine), Lower Saxony. The facility will have a storage capacity of 137.5 megawatts and a storage capacity of 275 megawatt hours, making it the largest approved storage project in Europe to date. The storage capacity in Alfeld exceeds the current largest facility in Europe by 50 percent. Construction of the facility is scheduled to start next year, with commissioning to follow by the end of 2025.
The storage project in Alfeld is a milestone in making the German electricity grid more flexible. Plants of this size make a significant contribution to stabilizing the electricity grid and strengthening the energy infrastructure. The capacity of the project in Alfeld is sufficient to supply one million households with electricity for one hour.
"It is essential for the success of the energy transition in Germany to massively expand storage capacities. Battery storage systems are indispensable for the integration of renewable energies into our electricity grids and the security of supply in Germany. The approval of the project in Alfeld is a decisive step towards a sustainable and independent energy future," says Florian Antwerpen, Managing Director of Kyon Energy.
In the past two years alone, Kyon Energy has commissioned storage projects with a capacity of over 120 megawatts. Further permits for almost half a gigawatt of storage capacity have now been granted. Kyon Energy will thus ensure the further expansion of around half of the current storage market in Germany (around 1.17 GW). This is a significant contribution to the success of the energy transition. The project in Alfeld is currently the largest approved plant.
Bernd Beushausen, Mayor of the town of Alfeld (Leine), comments: "We have found a reliable partner in Kyon Energy. The town is very proud that the company has decided to build its new large-scale battery storage facility here in Alfeld. We are therefore delighted to be working with Kyon Energy to ensure that the town of Alfeld (Leine) can also act as a role model for the south of the district of Hildesheim in the area of the energy transition from 2025."
The storage facility will be built near the substation. The high storage capacity makes it possible to store surplus energy from renewable energy sources and feed it back into the grid as required. The storage facility charges at times of low demand and low electricity prices, which is particularly the case when generation from renewable energy sources is high. In turn, it discharges at times of high demand and correspondingly expensive electricity prices - in other words, at times when there is little renewable electricity in the grid. In this way, storage systems not only promote the integration of renewables into the electricity mix, but also help to reduce the overall electricity price. Renewable energies can be better utilized and dependency on conventional energy sources is further reduced.
