Fluence and LEAG Clean Power begin second battery storage project in Germany

Fluence and LEAG Clean Power start the construction of their second battery storage project to support Germany’s energy transition

BERLIN and COTTBUS, Germany, Aug. 13, 2026 (GLOBE NEWSWIRE) — LEAG Clean Power GmbH and Fluence Energy GmbH, a subsidiary of Fluence Energy, Inc. (NASDAQ: FLNC) (Fluence), a global market leader delivering intelligent energy storage systems, services, and asset optimisation software, have started the deployment of the Heinersbrück GridBattery energy storage project. The project will be co-located with renewable generation assets on recultivated former mining land. It is designed to strengthen the security of energy supply and reduce pressure on the power grid.

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.

Thomas Brandenburg, Managing Director of LEAG Clean Power GmbH, said:

The Heinersbrück GridBattery is the first LEAG Clean Power battery storage system to share a grid connection point with wind and photovoltaic generation assets.

Brandenburg added,

This allows us to store surplus renewable electricity flexibly and make it available when it is needed.

”In doing so, we increase the efficiency of our energy system, relieve pressure on the power grid, and strengthen security of supply.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,”

Julian Jansen, Managing Director, Germany, at Fluence, said:

The Heinersbrück GridBattery is the second project we are delivering with LEAG Clean Power in the Lusatia region following GigaBattery Jänschwalde 1000.

”This adds to our strong track record in Germany, where we have contracted or deployed 35 projects with a cumulative capacity of over 6 GWh. 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,”
