EP Group, through its subsidiary LEAG Clean Power, has taken another major step in transforming the Jänschwalde energy site in Germany into a cornerstone of Europe’s future energy system. The investment will complement several renewable energy projects at the site with a cutting-edge, gigascale battery installation. GigaBattery Jänschwalde—set to become one of Europe’s largest battery storage project—will deliver 1 000 megawatts of power and 4 000 megawatt-hours of capacity.
This large-scale energy storage system will provide critical flexibility to the European power grid and enable the efficient use of growing volumes of renewable electricity. Once deployed, GigaBattery Jänschwalde—supplied by Fluence Energy and incorporating Fluence’s latest SmartStack technology—will be capable of storing and releasing energy equivalent to the daily electricity needs of approximately 420 000 households.
“For EP Group, this project represents another major step toward a sustainable energy future. Energy storage is indispensable for electricity systems that rely to a large extent on renewables—it supports system security and enables renewable power use even when the sun is not shining and the wind is not blowing. The future energy system will rely on renewables, fast-responding storage, and flexible power plants. With four-hour storage capability, we can use the existing grid connection more efficiently, balance longer periods of fluctuating renewables, and further strengthen security of supply,” said Tomáš David, Senior Executive of EP Group responsible for renewables, energy storage systems, and new business opportunities.
For EP Group, the Jänschwalde battery represents a further investment in the energy system of the future. Beyond grid stabilization, the project will create a platform for additional developments—linking renewable generation, new industrial applications, and innovative energy products. It is a central element of EP Group’s long-term strategy to transform the Lusatia region into a leading clean energy hub.
