Fluence and LEAG Clean Power have started construction on the 400 MWh Heinersbrück GridBattery in Germany, which will be co-located with wind and solar assets to enhance grid stability and support the country's energy transition. This project follows their earlier collaboration on a larger 1 GW / 4 GWh battery system, and both use Fluence's Smartstack technology to optimise renewable energy storage and supply security.
