Fluence and LEAG Begin Construction of Second Battery Storage Project
Fluence and LEAG Clean Power began construction of the Heinersbrück GridBattery, a second battery storage project in eastern Germany, targeting completion in 2027. Fluence will design, supply, and build both this project and the existing 1GW/4GWh GigaBattery Jänschwalde 1000. The systems use Fluence Smartstack and support Germany’s coal phase-out.
How this was made

The 30-second read
Why it matters
The Heinersbrück GridBattery is positioned as a second project, with Fluence responsible for design, supply, and construction, and powered by Fluence Smartstack modular battery technology.
Market read
A new Germany battery storage project adds to Fluence’s and LEAG Clean Power’s execution track record, but the article provides no financial terms.
What to watch
Grid-connection sharing and permitting timelines can drive schedule risk; the article does not address interconnection status, capex funding, or commissioning milestones beyond 2027 completion.
Background
Fluence and LEAG Clean Power are already deploying a 1GW/4GWh GigaBattery Jänschwalde 1000 system in eastern Germany.
Ticker impact
Fluence is named as the design, supply, and construction partner for the second LEAG Clean Power battery storage project in Germany.
Likely modest positive bias, mainly for longer-horizon order-book sentiment rather than a near-term repricing.
The article discloses a second joint project and Fluence’s scope, but provides no financial terms, capacity beyond the system type, or immediate earnings impact.
Market effects
Reinforces continued European grid-storage buildout tied to coal phase-out and renewable integration.
Highlights Lusatia, eastern Germany as an active storage cluster location with shared grid connection points.
Supports the broader narrative of scaling modular battery systems for renewable firming in Europe.
Counterpoint
Without contract value, financing terms, or performance guarantees, the news may be more about branding and pipeline than near-term earnings power.
