Luxcara has made a significant move in the Nordic energy market by acquiring this 125 MW ready-to-build Battery Energy Storage System (BESS) project in Finland, marking a key milestone in grid stability and sector leadership.
The acquisition of Project Tuisku significantly reinforces Luxcara’s presence in the Nordic region and contributes to grid stability in Finland’s dynamic, rapidly evolving power market. The addition of this large-scale battery energy storage system (BESS) project brings Luxcara’s total battery storage capacity under construction to nearly 1 GW, further strengthening its position as a leader in the sector.
With a planned capacity of 125 MW, Project Tuisku is anticipated to become one of the largest battery storage assets in Finland. The country’s increasing reliance on wind energy, coupled with a highly liquid power market, provides robust fundamentals for the development and operation of large-scale battery storage infrastructure.
The project is fully permitted, with a binding grid connection agreement secured. Construction began in 2024, and commercial operations are scheduled to start in the summer of 2027.
A long-term tolling agreement will provide stable, predictable revenue streams and further enhance the project’s bankability, appealing to institutional investors and lenders.
Luxcara, a German asset manager specialising in energy transition infrastructure, has acquired the Tuisku battery energy storage system in Finland. This milestone expands Luxcara’s storage portfolio, deepens its Nordic market presence, and emphasises its focus on grid stability and the integration of renewable energy. The project was acquired from Finnish developer Pohjan Voima.
Situated near Keminmaa in Southern Lapland, the Tuisku project benefits from a prime location adjacent to Fingrid’s 400 kV Keminmaa substation, ensuring direct integration with Finland’s high-voltage transmission grid. Construction is scheduled to commence in early 2026 and is expected to last approximately 18 months, with commercial operations projected to begin by summer 2027.
Janis Hoberg, Investment Director at Luxcara, says: “Battery storage is becoming a cornerstone of Europe’s power system, and Finland offers particularly strong fundamentals for flexible assets. Tuisku BESS combines advanced development status with an excellent grid location in a market well suited to utility-scale storage. This acquisition reflects Luxcara’s disciplined approach to building a diversified energy infrastructure portfolio.”
All necessary permits for the project have been secured, including full land rights and a legally binding grid connection agreement with transmission system operator Fingrid. Grid connection activities are already in progress, providing a high degree of certainty for the project’s execution. The long-term tolling agreement will provide stable revenues and strengthen the project’s risk profile, improving its overall bankability. Finland’s increasing share of renewable energy generation continues to drive demand for flexible grid solutions, reinforcing the commercial viability of large‑scale battery storage assets such as Tuisku.
Luxcara leverages its battery storage expertise as a key investor in the German Waltrop BESS site. With Tuisku, its battery storage capacity under construction is nearing 1 GW, illustrating rapid growth and a strong commitment to this asset class.
