Which energy storage technologies are being commissioned in Finland?

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.

Is energy storage the future of wind power generation in Finland?

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.

What factors influence the development of energy storage activities in Finland?

Several parameters are influencing the development of energy storage activities in Finland, including increased VRES production capacities, prospects to import/export electricity, investment aid, legislation, the electricity and reserve markets and geographic circumstances.

How much wind power will Finland have by 2035?

The range of wind power and electricity storage capacity estimated to be found in the Finnish electricity system by 2035 across the four different scenarios are listed in Table 2. The scenario with the highest amount of wind power had a combined onshore and offshore wind power capacity of 44 GW and a production of 141 TWh.

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.

How much does wind power cost in Finland?

Since 2019, wind power installations in Finland have been entirely commercially built and are mainly based on mutual power purchase agreements. The price levels for these agreements can be as low as 30 €/MWh , and onshore wind is currently the cheapest source of electricity in Finland .
