This paper has provided a comprehensive review of the current status and developments of energy storage in Finland, and this information could prove useful in future modeling studies of the Finnish energy system that incorporate energy storages.
With projects ranging from underground thermal vaults to cutting-edge battery systems, Finland''s approach to energy storage is about as diverse as its famous midnight sun phases.
SEB Nordic Energy''s portfolio company Locus Energy, in collaboration with Ingrid Capacity, proudly announces the groundbreaking of one of Finland''s largest battery energy storage system (BESS) in Nivala Municipality, Northern Ostrobothnia.
Finland is expected to operate more than 300MW of grid-scale battery energy storage systems in the next two years, according to data from LCPDelta''''s StoreTrack database.
This paper has provided a comprehensive review of the current status and developments of energy storage in Finland, and this information could prove useful in future modeling studies of the Finnish energy system that incorporate energy storages.
Currently, utility-scale energy storage technologies that have been commissioned in Finland are limited to BESS (lithium-ion batteries) and TES, mainly TTES and Cavern Thermal Energy Storages (CTES) connected to DH systems.

Energy storage systems offer a solution. “This groundbreaking is an important moment for Finland’s energy transition and a concrete step toward a more flexible, resilient, and decarbonized energy system,” said Jussi Jyrinsalo, Senior Vice President at Fingrid.
Wind power generation is estimated to grow substantially in the future in Finland. Energy storage may provide the flexibility needed in the energy transition. Reserve markets are currently driving the demand for energy storage systems. Legislative changes have improved prospects for some energy storages.
This development forebodes a significant transition in the Finnish energy system, requiring new flexibility mechanisms to cope with this large share of generation from variable renewable energy sources. Energy storage is one solution that can provide this flexibility and is therefore expected to grow.
