Press releases | 18 September 2025

Led by partners Dr. Tim Heitling and Dr. Carla Luh, global law firm Hogan Lovells has advised Terra One Climate Solutions GmbH on the €150m mezzanine financing for the development and construction of battery energy storage systems (BESS) across Europe.

Berlin-based startup Terra One has raised €150m from asset manager Aviva Investors to finance its grid-scale battery storage facilities. The company is an innovative provider of large-scale battery storage solutions in Germany, enabling the storage of surplus energy from renewable sources and its flexible feed-in to the power grid when needed. Since 2022, Terra One has combined advanced storage technology with machine-learning solutions to stabilize the grid, use renewable energy efficiently, and drive the energy transition forward. The financing gives Terra One the ability to execute its near-term project pipeline and establish Terra One as one of Europe’s leading independent flexibility providers. Combined with equity and project financing, this gives Terra One the ability to invest up to 750 million in new storage projects.

Hogan Lovells provided Terra One with comprehensive advice on the financing and corporate aspects of the transaction. The Hogan Lovells team regularly advises on innovative financings and pioneering energy transactions, and is recognized as a leading advisor for complex and high-profile projects in the renewable energy sector.
