First 220 MWh BESS project in Finland
SMA Altenso to realize first 220MWh battery energy storage project in Finland
Niestetal, 23 April, 2026 – Finland is emerging as a key market for advanced energy storage solutions, driven by a rapid expansion of renewable energies, increasing power price volatility, and rising grid stability requirements. Building on its strong engineering track record and extensive project development and delivery experience, SMA Altenso is entering this promising market to deliver efficient and investor-ready solutions. A first battery energy storage system (BESS) with the capacity of 95 MW and 220 MWh will be realized in Alapitkä, in the municipality of Lapinlahti, Finland.
The so-called Battery Park Alapitkä is a stand‑alone, ready‑to‑build, utility‑scale BESS project developed entirely by Altenso in collaboration with its local partner Infinergies Finland Oy. BESS plays a strategic role in Finland’s energy transformation.
Altenso and re:cap are joining forces

The Battery Park Alapitkä sets new technological standards using advanced grid-forming inverter technologies by SMA to ensure reliable operation and stable performance under demanding conditions. The Sunny Central Storage UP-S, delivering power conversion efficiency through SiC Mosfet semiconductors, combine performance, reliability, and cybersecurity compliance. The inverters are mounted on a Medium Voltage Power Station in a 40-ft configuration, giving EPCs and project developers double the power in a single turnkey unit, simplifying the system design and installation.
Altenso transfers Battery Park Alapitkä to re:cap
The global greentech investor re:cap has reached an agreement to fully acquire in Altenso’s Battery Park Alapitkä on behalf of the FP Lux European Battery Storage fund. By this move, re:cap strengthens its position in the rapidly expanding European BESS market, benefiting from its involvement in this high-growth sector from an early stage.
Altenso co-developed the project with Infinergies Finland Oy and will execute the full EPC scope, managing balance of plant, medium to-high voltage construction and grid integration.The Battery Park Alapitkä is scheduled for operation in 2027.
