Average office building energy storage price per 1MW in Finland

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 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.

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.

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 .

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.

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.
