LEAG Clean Power integrates solar photovoltaic and wind energy systems with flexible power plants and large-scale storage facilities across the Lusatian energy region and other locations in Germany. This integrated approach is known as the GigawattFactory. 

LEAG Group CEO Adi Roesch said: “With this project, we are igniting another growth engine for our GigawattFactory. By constructing gigascale storage facilities, we are addressing one of the biggest challenges of the energy transition: the constant availability of energy regardless of the availability of renewable energies.  

“The key to the energy system of the future lies in a combination of renewable energies, storage facilities that can be used as needed, and flexible power plants.” 

The GigaBattery Jänschwalde 1000 project is built to deliver essential grid services, enable efficient energy trading, strengthen Germany’s energy security, and accelerate the country’s energy transition.
