Fluence Energy and LEAG Clean Power GmbH announced a 1 GW/4 GWh battery storage facility in Jänschwalde, Germany, that will deploy Fluence’s Smartstack platform—the company’s first large‑scale AC‑based, high‑density system. The project will provide grid‑stability services, support renewable integration, and help meet European decarbonization targets.
The deal marks a strategic milestone for Fluence. It is the first time the Smartstack architecture is being used at this scale, and it positions the company as a key player in Germany’s growing storage market. The Jänschwalde site is part of LEAG’s “GigawattFactory” strategy, which couples renewable generation with flexible power plants and storage, giving Fluence a foothold in a high‑growth segment of the European market.
Fluence’s recent financial results contextualize the significance of the contract. In Q3 2025, the company reported revenue of $602.5 million, up 24.7% YoY, but its GAAP gross‑profit margin fell to 14.8% from 17.2% the prior year, reflecting pricing pressure and higher input costs. Adjusted EBITDA rose to $27.4 million, but the company’s backlog remained strong at $4.9 billion. Despite the revenue growth, Fluence lowered its FY 2025 revenue guidance to $2.6 billion–$2.8 billion and adjusted EBITDA guidance to $0–$20 million, citing slower U.S. production ramp‑up and tariff uncertainty. The Jänschwalde contract, therefore, represents a tangible revenue source that could help offset these headwinds and support the company’s long‑term growth trajectory.
Analysts have responded cautiously to Fluence’s guidance revisions and recent profitability challenges. The company’s average 12‑month price target remains well below its current valuation, and the consensus rating is largely “Hold” or “Reduce.” The primary driver of this sentiment is the repeated downward revision of FY 2025 guidance and the year‑over‑year revenue declines in Q1 and Q2 2025, which have raised concerns about execution risk and market conditions. The strong backlog, however, provides a counterbalancing narrative that the company still has significant future revenue potential.
CEO Julian Nebreda emphasized that the Smartstack platform “redefines how energy storage systems are designed, built, and maintained,” and highlighted the Jänschwalde project as a proof of concept for large‑scale deployment. CFO Manavendra Sial noted that the company is executing legacy low‑margin backlog while targeting adjusted EBITDA breakeven in Q4 2023, underscoring a focus on cost discipline amid market uncertainty.
The Jänschwalde project aligns with Fluence’s broader strategy to expand its footprint in Europe and accelerate the adoption of its Smartstack technology. While the contract adds a substantial revenue stream, the company must navigate tariff risks, production ramp‑up delays, and competitive pressures. Successful execution of this project could strengthen Fluence’s market position and provide a template for future large‑scale deployments, but the company’s ability to convert its backlog into timely, profitable revenue remains a key risk factor.
