Daiwa Acquires 49% Stake in 157 MW German Solar Project with 80 MWh Battery Storage

Germany | October 15, 2026-Japanese investor Daiwa Energy & Infrastructure (DEI) has acquired a 49% stake in the Elsterheide solar photovoltaic (PV) and battery energy storage project in Saxony, Germany, from independent renewable energy developer AMPYR Solar Europe (ASE). The recently commissioned project combines a 157 MWp solar power plant with an 80 MWh battery energy storage system (BESS).

AMPYR Solar Europe will retain the remaining 51% stake and continue to operate and manage the assets. The transaction also establishes a foundation for a longer-term partnership, under which ASE will develop and manage renewable energy projects while Daiwa invests as a long-term partner during their operational phase. Financial details of the transaction have not been disclosed.

Integrated Solar and Storage Enhances Grid Flexibility

Located across more than 130 hectares in the municipalities of Elsterheide and Hoyerswerda, the project integrates utility-scale solar generation with battery storage. The BESS can charge using electricity generated by the solar plant or electricity drawn from the grid, enabling it to support energy management and provide balancing services to the local power network.

The project features a diversified revenue structure, including a long-term power purchase agreement (PPA) covering 120 MWp of solar capacity, a battery optimization agreement and the sale of Guarantees of Origin. An additional 40 MW of solar capacity receives support under Germany’s Renewable Energy Sources Act (EEG).

Investment Partnership Supports Renewable Energy Growth

The transaction highlights the growing role of institutional investors in financing operational renewable energy assets. For developers, selling a minority stake can release capital for future projects while preserving operational control and long-term participation in asset performance.

For investors, combining solar generation with battery storage offers opportunities to participate in Germany’s energy transition while diversifying revenue streams through contracted electricity sales, storage optimization and market-based trading.

As renewable energy penetration increases across Europe, integrated solar-plus-storage projects are becoming an important component of a more flexible electricity system.

The Elsterheide transaction illustrates how strategic investment partnerships can support the continued development and commercialization of large-scale renewable energy infrastructure.
