Sungrow deploys big battery storage system in Finnish Arctic

Chinese inverter and energy storage manufacturer Sungrow has successfully deployed a 60 MWh battery energy storage system (BESS) in Simo, Finland, situated just over 100 kilometers south of the Arctic Circle. This installation, comprising 26 of Sungrow’s PowerTitan liquid-cooled battery containers, is part of a joint venture between Fotowatio Renewable Ventures (FRV) and AMP Tank Finland Oy. The project aims to enhance grid stability and support Finland’s transition to renewable energy sources.

The PowerTitan system integrates a 5 MWh battery with a 2.5 MW power conversion system (PCS) into a single 20-foot container, utilizing a liquid-cooled design. According to the manufacturer, this configuration ensures efficient heat dissipation, extending system longevity and maintaining high performance even in extreme cold conditions. The system boasts a roundtrip efficiency of 89.5% and incorporates AI-based battery health management system, enhancing safety and operational reliability.

Located near Fingrid’s Simojoki substation in Lapland, the BESS occupies a 0.4-hectare site and plays a critical role in balancing the intermittency of renewable energy sources like wind and solar. By storing excess energy during periods of low demand and releasing it during peak consumption, the system contributes to a more resilient and sustainable power grid.

Hannu Koivusalo, Chairman of AMP Tank, highlighted the decision to partner with Sungrow, citing the company’s technological reliability and comprehensive support services as key factors. “Sungrow’s expertise ensures that our energy storage solutions operate effectively under the challenging conditions of the Arctic environment,” Koivusalo stated.

The deployment in Simo marks Sungrow’s continued expansion into the European energy storage market, following previous installations in the UK and other regions. With the potential for future expansion to 200 MWh, the company’s latest project underscores the growing importance of advanced energy storage systems across all geographies.
