Energy Storage Under Extreme Conditions: Sungrow Delivers Large-Scale Battery Storage Near the Arctic Circle

Hefei, China – The Chinese energy storage specialist Sungrow has commissioned a large-scale battery storage system in Simo, Finland, located just 100 kilometers south of the Arctic Circle. The project was developed in cooperation with the joint venture FRV Amp-Tank. The company develops battery storage solutions for both short-term and long-term storage.

This project is one of the northernmost battery storage systems in the world. The facility consists of 26 Power-Titan containers from Sungrow, equipped with liquid-cooled lithium iron phosphate batteries designed for operation in extreme climatic conditions. With a power output of 30 MW and a storage capacity of 60 MWh, the system ensures grid stability, balances peak loads, and enables reliable integration of fluctuating wind and solar power.

Special attention was given to a combination of technical reliability, high efficiency, and low maintenance requirements in the project. Due to the compact container design, the system was pre-assembled and delivered, allowing for quick on-site installation – a significant advantage in remote regions such as northern Finland, emphasizes Sungrow.

“Our products are designed to operate in demanding conditions, ensuring stability and efficiency for Finland’s renewable energy grid and our customers,” says Henry Särkisilta, Key Account Manager at Sungrow Finland.

Hannu Koivusalo from Amp-Tank lists two main reasons for choosing Sungrow as the supplier of the BESS. "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,” says Koivusalo.
