Prime Capital has acquired the Tuovila Battery Energy Storage System (BESS) in Finland six months after Futureal Energy Partners provided finance to fund the completion of the project.
The 125MW battery energy-storage system, which can provide up to four hours of energy, was developed by Finnish renewables company Aurinkokarhu Oy.
In September 2025, Futureal Energy Partners issued a development loan to Aurinkokarhu Oy to fund the remaining development costs required to bring the Tuovila BESS project to a ready-to-build stage, while also supporting a sale process.
The project was then sold to German alternative asset manager Prime Capital “on a timeline that exceeded initial expectations”, Futureal Energy Partners said.
Daniel Szentirmai, co-founder and CEO of Futureal Energy Partners, said: “This transaction demonstrates how targeted development financing can accelerate high-quality energy-storage projects and bring them to market efficiently.
“The Tuovila BESS project is not only a strong commercial success, but also a strategic investment in grid stability and flexibility. We are proud that this marks Futureal Energy Partners’s entry into the Finnish renewables market, where we see further attractive opportunities ahead.”
Construction of the Tuovila BESS project is expected to start in the second quarter of 2026, with commercial operations planned for early 2027.
Andreas Renfällt, CEO of Aurinkokarhu Oy, said: “We highly value our cooperation with Futureal Energy Partners. Their development financing and transactional expertise provided valuable support throughout the successful sales of Tuovila BESS. This project underlines the growing importance of battery energy storage in Finland and across the Nordics.
“The transaction reflects the shared commitment of Aurinkokarhu and Futureal Energy Partners to advancing innovative, flexible energy solutions that support the integration of renewables and the long-term stability of Europe’s power systems.”
