The GigaBattery Jänschwalde 1000, an innovative energy storage project, will soon establish its presence in Germany’s progressive world energiewende. This ambitious project is impressive enough in its capacity of 1 gigawatt (GW). Its goal is to enhance the nation’s energy security and accelerate the adoption of sustainable energy technologies. LEAG Clean Power and Fluence have made a powerful alliance. Coupled together, they help ensure this project is the heart of the GigawattFactory, which seeks to be an incubator for advanced energy storage technology innovation.
The signing ceremony for the GigaBattery Jänschwalde 1000 project took place shortly before November 7, 2025. This event has produced a historic opportunity for the energy future of Germany and all Europe. This groundbreaking project will deploy Fluence’s advanced energy storage solution, Smartstack, which is engineered to deliver essential grid services and facilitate efficient energy trading.
Project Overview and Objectives
The GigaBattery Jänschwalde 1000 project is smartly tailored to tackle critical challenges facing the energy industry. With its ability to deliver dependable energy storage, it helps guarantee that no matter what changes happen with renewable energy sources, you still have consistent energy. This new capability is no small thing as Germany strives to shift from a fossil-fuel dependent power system to a more sustainable one.
Fluence President and CEO Julian Nebreda painted an optimistic picture for this new partnership.
“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.” – Julian Nebreda
Integrating Smartstack technology will provide a new path to satisfying grid reliability requirements. It will establish a more competitive market for energy exchange, which will in the long run lower electricity costs for consumers.
Commitment to Energy Security
The German federal government has so far not disputed the fact that energy storage plays a crucial role in ensuring a secure power system. With the GigaBattery Jänschwalde 1000 project, officials believe they are taking substantial steps toward ensuring that energy demands are met seamlessly. This initiative is EU’s broader efforts to improve energy security throughout Europe.
Staying successful in this fast-changing energy landscape calls for creative approaches. The GigaBattery Jänschwalde 1000 project offers an example of how storage facilities will play a significant role in establishing a safe, manageable energy system. It would address one of the most painful challenges we face in moving to renewable energy.
Adi Roesch from LEAG Clean Power remarked on the project’s significance:
“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.” – Adi Roesch
Impact on Energy Transition
Germany’s passion for evolving toward a green future is inspiring. Projects such as Estonia’s GigaBattery Jänschwalde 1000 initiative will be key to achieving national and European climate targets. The partnership between LEAG and Fluence is a strong acknowledgment that innovation and sustainability are the new normal in energy production and consumption.
By enhancing grid services and enabling efficient trading mechanisms, this project is expected to significantly contribute to affordable and sustainable power systems in Germany. Now, more countries are clamoring to be the next to implement similar technologies. We fondly appreciate the GigaBattery Jänschwalde 1000 project as a star on the rise, of success in Europe’s energy transition.
