Global solar and energy storage leader Sungrow has announced the successful commissioning of a 60MWh Battery Energy Storage System (BESS) project in Simo, Finland, marking one of the northernmost battery power plants in the world. Developed in partnership with FRV AmpTank, the project is a major step in bolstering grid stability and renewable energy integration in the Nordic region.
Located less than 100 km south of the Arctic Circle, the installation comprises 26 Sungrow PowerTitan battery containers, delivering 30MW of power output and 60MWh of storage capacity. This deployment supports Finland’s growing reliance on wind and solar power, ensuring a more resilient and responsive energy grid.
The PowerTitan system, Sungrow’s flagship liquid-cooled BESS tailored for utility-scale applications, is designed to withstand extreme weather conditions while maintaining high efficiency and reliability. Housed in 20-foot pre-assembled containers, the system enables rapid installation and modular scalability. The use of safe lithium iron phosphate batteries with liquid cooling ensures durability and minimal maintenance—an advantage in the region’s harsh environment.
Hannu Koivusalo, Chairman of AmpTank, remarked: “There were two main reasons why we selected Sungrow. The first was technical reliability. Sungrow’s technology convinced us that it would perform reliably under all conditions. The second key factor was long-term reliability, specifically maintenance, servicing, and related support, where Sungrow offered us a very competitive package.”
Henry Särkisilta, Key Account Manager at Sungrow Finland, added: “It has been a pleasure to be part of delivering one of the world’s northernmost battery power plants in collaboration with FRV AmpTank. Our products are designed to operate in demanding conditions, ensuring stability and efficiency for Finland’s renewable energy grid and our customers. At the same time, our team of experts is fully dedicated to supporting our partners’ efforts towards our common path towards a sustainable future.”
The Simo BESS project underscores Sungrow’s commitment to “Clean power for all” by showcasing the role of intelligent energy storage in enabling a clean and stable grid. As Finland advances its transition to renewable energy, such projects highlight the importance of coupling clean generation with cutting-edge storage technologies for long-term sustainability and energy security.
