Greenlight for ‘Europe’s largest’ battery project in Germany

Kyon Energy received approval for a 137.5MW/275MWh battery project that will be located near a substation, charging and discharging as per renewable availability to help shave peak demand from Germany’s power grid.

The battery storage project will be located in Alfeld (Leine), Lower Saxony, Germany.

According to the project development company of large-scale battery energy storage systems, the facility will be the largest approved storage project on the continent to date, surpassing the current record holder in Europe by 50%.

The storage facility will be built near a substation, its high storage capacity making it possible to store surplus energy from renewable sources and feed it back into the grid as needed.

To do so, the facility will charge at times of low demand and favourable electricity prices, especially when generation from renewable sources is high. It will then discharge at times of high demand and correspondingly expensive electricity prices – i.e., at times when there is little renewable electricity in the grid.

The project is being called a milestone in Germany by Kyon for increasing the flexibility of the power grid; according to the company, the project’s capacity will be enough to supply one million households with electricity for one hour.

“For the success of the energy transition in Germany, it is essential to massively expand storage capacities. Battery storage is indispensable for the integration of renewable energies into our power grids and for security of supply in Germany.

“The approval of the project in Alfeld is a decisive step towards a sustainable and independent energy future,” stated Florian Antwerpen, managing director of Kyon Energy.

The mayor of Alfeld (Leine), Bernd Beushausen, added: “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 act as a role model for the district of Hildesheim in the area of the energy transition from 2025.”

Construction of the plant is scheduled to start next year, with commissioning to follow by the end of 2025.

In the past two years, Kyon Energy has commissioned storage projects with a capacity of over 120MW.

Further permits for almost half a gigawatt of storage capacity have now been granted, supporting Kyon Energy in its ambition to ensure the further expansion of half of the current storage market in Germany (around 1.17GW).
