Green Flexibility Secures €1 Billion Boost to Revolutionize Europe's Energy Storage Market

Green Flexibility Secures €400 Million Funding to Propel Europe's Energy Transition

Berlin, January 16, 2025 – In a significant boost to Europe’s renewable energy landscape, Green Flexibility, a leading German developer of large-scale battery energy storage systems (BESS), has secured an initial equity commitment of €400 million from Partners Group, a global private markets investment firm. This substantial funding, complemented by additional debt financing, brings the total investment to over €1 billion, enabling Green Flexibility to accelerate its ambitious battery energy storage projects across Europe.

Company Background and Expertise

Founded in 2023 by industry veterans Christoph Ostermann, Hermann Schweizer, Christoph Lienert, and Bernd Arkenau, Green Flexibility has rapidly emerged as a pivotal player in the European energy sector. The company specializes in the development, construction, and operation of large-scale battery storage systems, offering a comprehensive approach that spans every project phase—from site identification to the marketing of storage solutions.

The founders bring a wealth of experience to the table, having developed Europe’s first virtual power plant a decade ago. This pioneering initiative underscored the critical role of grid flexibility in ensuring stability and sustainability, a principle that continues to guide Green Flexibility’s mission today.

Market Need and Solution

Europe's energy landscape is undergoing a profound transformation, characterized by the rapid expansion of renewable energy sources and the gradual decline of conventional base-load power plants. This shift has introduced significant fluctuations in electricity generation, leading to heightened price volatility and grid instability. Green Flexibility addresses these challenges through its innovative BESS projects, which offer multiple benefits:

1. Energy Storage: Capturing excess energy during periods of high generation.
2. Energy Release: Supplying stored energy when demand peaks.
3. Grid Stabilization: Enhancing the reliability of the power grid.
4. Curtailment Reduction: Minimizing the wastage of renewable energy.
5. Price Smoothing: Stabilizing energy costs for consumers and businesses.

By implementing these solutions, Green Flexibility plays a crucial role in balancing the intermittent nature of renewable energy, thereby supporting the broader goal of a sustainable and resilient energy grid.

Strategic Partnerships and Approach

Green Flexibility’s success is underpinned by its strategic collaborations with other project developers and grid operators. By working closely with grid operators, the company ensures that local grid requirements are seamlessly integrated into project implementations. This collaborative approach not only enhances grid stability but also positions Green Flexibility as an industry pioneer in addressing the complexities of energy storage integration.

Moreover, the partnership with Partners Group brings invaluable financial and strategic support, while the collaboration with Cellect Energy leverages advanced asset management platforms to oversee Green Flexibility’s extensive +8 GW energy storage project pipeline. These alliances underscore the company’s commitment to technological excellence and operational efficiency.

Future Plans and Market Position

With the secured €1 billion in funding, Green Flexibility is poised to scale its operations and achieve market leadership in Europe’s largest electricity market. The company aims to execute its extensive project pipeline, which exceeds 10 gigawatts, and establish itself as a key player in the rapidly growing BESS sector.

Christoph Ostermann, CEO of Green Flexibility, emphasized the importance of quality, safety, and reliability in the battery storage market. “Our focus on these core aspects, combined with our experienced team, positions us well to address the challenges of the energy transition,” Ostermann stated. David Daum, Partner and Head of Infrastructure Europe at Partners Group, echoed this sentiment, highlighting the opportunity to build a significant battery storage platform in Europe’s expansive power market.
