The project will have a capacity of 1GW.
LEAG Clean Power specializes in integrating solar photovoltaic and wind energy systems with flexible power plants and large-scale storage facilities across the Lusatian energy region and other parts of Germany. This approach, known as the GigawattFactory, combines renewable generation with storage and flexible power solutions to ensure a reliable energy supply.
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 is designed to provide essential grid services, enable efficient energy trading, strengthen Germany’s energy security, and accelerate the country’s energy transition. By delivering large-scale, flexible storage, the project will help balance supply and demand, making renewable power more reliable and accessible.
Fluence President and CEO Julian Nebreda said: “We are proud to partner on a project of this scale and importance and congratulate LEAG Clean Power on this milestone for the energy future of Germany and Europe. This flagship project demonstrates that when expertise, vision, and courage come together, a major transformation is possible. Together, we can transform the energy system and thus the foundation of our economy and our everyday lives.”
The German government has emphasized that energy storage is essential for maintaining a secure, affordable, and sustainable power system. Projects like GigaBattery Jänschwalde 1000 are central to supporting large-scale renewable integration while ensuring grid stability and reliability.
The collaboration between LEAG and Fluence is expected to enhance system stability and facilitate the continued expansion of renewable energy across Germany. By combining cutting-edge storage technology with renewable generation and flexible power plants, the project aims to serve as a model for Europe’s energy transition and support long-term sustainability goals.
Overall, the GigaBattery Jänschwalde 1000 project represents a major step toward a resilient, renewable-based power system, demonstrating how large-scale energy storage can complement renewable generation and strengthen energy security across the region.
