Longi’s First Finland Battery Goes Live as Nordic Storage Race Heats Up
Longi Green Energy Technology has rolled out its first energy storage system in Finland—a modest 2 MW/4 MWh battery, but one that's drawing attention thanks to its integration with the Söderby Solpark solar installation on the Åland Islands. According to Longi Energy Storage, the BESS works alongside a 4 MW solar array on site. Capacity is 4 MWh, a figure that tracks the total electricity the battery can hold. Timing is critical as Finland ramps up weather-dependent energy sources and needs batteries to manage volatile supply. By early February, roughly 1,050 MW of storage had been plugged into the Finnish grid, grid operator Fingrid said. The company also cautioned that new battery sites need to be chosen carefully to prevent
