6 Frequently Asked Questions about “Finland energy storage power station”

Is energy storage a viable option in Finland?

This study reviews the status and prospects for energy storage activities in Finland. The adequacy of the reserve market products and balancing capacity in the Finnish energy system are also studied and discussed. The review shows that in recent years, there has been a notable increase in the deployment of energy storage solutions.

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 the energy system still working in Finland?

However, the energy system is still producing electricity to the national grid and DH to the Lempäälä area, while the BESSs participate in Fingrid's market for balancing the grid . Like the energy storage market, legislation related to energy storage is still developing in Finland.

What is the storage capacity of water tank thermal energy storage in Finland?

Water TTESs found in Finland are listed in Table 7. The total storage capacity of the TTES in operation is about 11.4 GWh, and the storage capacity of the TTES under planning is about 4.2 GWh. Table 7. Water tank thermal energy storages in Finland. The Pori TTES will be used for both heat and cold storage.

Can PHS be used as energy storage in Finland?

Plans exist for PHS systems, but studies have indicated that there may be few suitable locations for PHS plants in Finland [94, 95]. While large electrolyzer capacities are planned to produce renewable hydrogen, only pilot-scale plans currently exist for their use as energy storage for the energy system (power-to-hydrogen-to-power).

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.
