Tuovila BESS Project – Entering the Construction Phase
- March 16, 2026
At the end of 2025, Aurinkokarhu reached an agreement with Prime Capital AG regarding the continued development of the Tuovila BESS project, a battery energy storage system located in the municipality of Mustasaari on the west coast of Finland.
The project is currently one of the largest BESS initiatives in Finland, with a planned capacity of 125 MW/500 MWh. This project will play an important role in strengthening Finland’s energy storage capacity and supporting the ongoing transition toward a more resilient and renewable energy system.
The successful development of the project has been made possible through close cooperation with local stakeholders and Aurinkokarhu’s trusted advisors Etha Oy, Futureal Energy Partners, and Hillforth Development AB.
The entire Aurinkokarhu team would like to extend our sincere thanks to everyone involved, and especially to the landowners, the municipality, and the grid operator for their constructive collaboration throughout the development process. We look forward to continuing to monitor and support the development and construction of the BESS facility, which is expected to be completed in 2027.
