Fluence Energy, LEAG start construction of BESS in Germany

LEAG Clean Power GmbH and Fluence Energy GmbH, a subsidiary of Fluence Energy, Inc., have started the deployment of the Heinersbrück GridBattery energy storage project in Germany. The project will be co-located with renewable generation assets on recultivated former mining land, Fluence said.  

The Heinersbrück GridBattery, scheduled for completion in 2027, is the second joint project for Fluence and LEAG Clean Power. The companies are already deploying the 1GW / 4 GWh GigaBattery Jänschwalde 1000 system in the same part of the country, in eastern Germany. 

Fluence is responsible for the design, supply, and construction of both projects. They will be powered by Fluence Smartstack, a high-density, high-availability, modular battery solution known for its advanced safety and ease of deployment.

As part of Germany’s coal phase-out, LEAG Group is repurposing former mining areas, existing industrial sites, and energy infrastructure to develop its GigawattFactory, an integrated system of renewable generation, battery storage, and dispatchable power plant capacity designed to support the energy transition.

“The Heinersbrück GridBattery is the first LEAG Clean Power battery storage system to share a grid connection point with wind and photovoltaic generation assets,” said Thomas Brandenburg, Managing Director of LEAG Clean Power GmbH. “We are pleased to have Fluence as an experienced and highly capable partner, supporting us both at the Heinersbrück and Jänschwalde power plant sites as we build a battery storage cluster of national and European significance.”  

“As a company with deep German heritage, we share LEAG’s ambition of establishing large-scale energy storage as a key pillar of a modern and resilient German energy system,” said Julian Jansen, Managing Director, Germany, at Fluence.
