FAQs 5

Is this Finland's largest battery energy storage system?

Swedish flexible assets developer and optimizer Ingrid Capacity has joined hands with SEB Nordic Energy’s portfolio company Locus Energy to develop what is claimed to be Finland’s largest and one of the Nordics’ largest battery energy storage systems (BESS). The 70 MW/140 MWh BESS project will be located in Nivala, northern Finland.

Does Finland have energy storage?

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.

Is energy storage a viable solution for the Finnish energy system?

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.

How can a Finnish energy system be modeled?

The energy system could be modeled with a tool such as EnergyPLAN, considering the effects of a much larger share of RES in the Finnish energy system and the need for flexibility from ESSs. In collaboration with this study, a survey was conducted among the Finnish BRPs about their views and needs regarding ESSs.

What are battery energy storage systems?

Battery energy storage systems Battery energy storage systems are currently the only utility-scale energy storages used to store electrical energy in Finland. BESSs are suitable for providing FCR and FFR services. BESSs provide rapid reaction times: full power can be achieved in a matter of hundreds of milliseconds .
