Chinese group Sungrow Power Supply Co. Ltd has completed the commissioning of a battery energy storage system with a capacity of 60MWh in Simo, Finland. Developed in partnership with the joint venture FRV AmpTank, the project is among the world’s northernmost storage facilities, according to a statement released on May 27.

A strategic project in an extreme zone

Located less than 100 kilometres south of the Arctic Circle, the site includes 26 PowerTitan containers manufactured by Sungrow. The system provides an output of 30MW and a total storage capacity of 60MWh. The installation aims to stabilise the local energy grid as Finland increases the share of renewable sources such as wind and solar.

Sungrow’s PowerTitan is a liquid-cooled Battery Energy Storage System (BESS) designed for large-scale applications. The 20-foot containerised format enables simplified transport and installation, thanks to pre-assembly carried out at the factory. This compact format also allows for back-to-back installation without performance loss.

Design suited to Nordic conditions

The batteries use lithium iron phosphate technology with a liquid circulation cooling system, designed to reduce maintenance needs and ensure stable performance in harsh weather conditions. The design aims to maximise technical reliability while limiting on-site interventions.

“There were two main reasons for choosing Sungrow: technical reliability and the guarantee of long-term support,” said Hannu Koivusalo, Chairman of the AmpTank joint venture. He specified that the maintenance and service commitments offered by the Chinese group were a decisive factor in their decision.

Henry Särkisilta, Key Account Manager at Sungrow Finland, stated that the project reflects the adaptability of their systems to demanding environments, highlighting the local team’s involvement in the technical deployment of this infrastructure.
