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.
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.
Like the energy storage market, legislation related to energy storage is still developing in Finland. The two are intertwined as who is allowed to own and operate energy storages will define the business models of the storages. A major barrier to the implementation of ESS was removed when the issue of double taxation was solved.
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.
