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 does the Finnish TSO respond to the growing number of renewable installations?

The Finnish TSO, Fingrid, is continuously taking measures to respond to the fast-growing number of renewable installations. The power system is getting more complicated both from a technical and commercial perspective, with many large changes occurring simultaneously both in electricity production and consumption.

Can ESSs solve intermittent power production in Finland?

The growth of wind deployments influences both the electricity system and the electricity markets. ESSs are one main solution to tackle intermittent power production, but in Finland, there are so many wind projects in the pipeline that ESSs alone cannot solve this issue.

How do EU-funded hydrogen projects work in Finland?

There is a variety of EU-funded financial tools and incentives for hydrogen projects . The affordable low-carbon electricity grid, the high availability of new VRES, and the willingness to pay from local offtakers, are making Finland attractive for European renewable hydrogen projects.

What are some examples of GWh-scale borehole thermal energy storage in Finland?

Examples of larger GWh-scale borehole thermal energy storages built in Finland include one built at a logistics center in Sipoo and an underground parking lot in Turku . Normally, the depth of the boreholes for ground-source heating and in borehole thermal energy storages is a few hundred meters at most.
