Fluence and LEAG Clean Power Launch Second Battery Storage Project in Germany
Event summary
- Fluence and LEAG Clean Power began construction on the Heinersbrück GridBattery project in eastern Germany, scheduled for completion in 2027.
- The project is co-located with renewable generation assets on recultivated former mining land and will use Fluence’s Smartstack™ battery solution.
- This is the second joint project between Fluence and LEAG Clean Power, following the 1GW / 4 GWh GigaBattery Jänschwalde 1000 system currently under deployment.
- Fluence has contracted or deployed 35 projects in Germany with a cumulative capacity of over 6 GWh.
The big picture
This project is part of Germany’s broader coal phase-out strategy, with LEAG Group repurposing former mining areas to develop its GigawattFactory—a system integrating renewable generation, battery storage, and dispatchable power. Fluence’s involvement underscores the growing demand for intelligent energy storage solutions in Europe’s transition to a more resilient grid.
