Germany’s Green Flexibility secures up to EUR 400m equity finance for grid-scale batteries

Green Flexibility wants to plan, build, and operate battery storage systems at strategically important points in the grid across Europe, taking on all project steps, from identifying sites to marketing the resulting facilities.
The company, founded in the Bavarian town of Kempten in 2023 – and whose team includes the founder and former CEO of battery maker Sonnen, Christoph Ostermann – has completed a financing round with Partners Group. A statement issued on Jan. 16, 2025 indicated the Swiss private equity firm is investing up to EUR 400 million in Green Flexibility, which, with the latter’s additional debt capital, should enable a project volume of more than EUR 1 billion worth of sites.
Green Flexibility wants to use the money to establish itself as a market leader. The company website states Green Flexibility’s current project pipeline includes more than 10 GW of battery storage facilities, more than 100 MW of which are ready for construction.
“With Partners Group, we have the ideal partner to scale our company and realize our vision of a sustainable and, above all, reliable energy future,” said Green Flexibility CEO Ostermann. The company wants to cooperate with other project developers and announced a large-scale battery storage partnership with Allgäuer Überlandwerk in August 2024.
The Kempten-based developer said it will integrate the local grid requirements of electricity network operators into its projects.
