Finland s user-side energy storage capacity regulations

Is energy storage legal in Finland?

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.

Does Finland have a capacity mechanism to protect electricity supply in Finland?

The European Commission has approved, under EU State aid rules, a €150 million Finnish capacity mechanism to safeguard security of electricity supply 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.

Does Finland have a capacity mechanism?

To ensure the balance between supply and demand during scarcity hours, Finland has a capacity mechanism – strategic reserve. The Energy Authority is responsible for evaluating and deciding the required size of the strategic reserve capacity and arranging the tendering process to procure the capacity.

What is the future of energy storage in Finland?

Reserve markets are currently driving the demand for energy storage systems. Legislative changes have improved prospects for some energy storages. Mainly battery storage and thermal energy storages have been deployed so far. The share of renewable energy sources is growing rapidly in Finland.

Will Finnish electricity generation capacity be available during peak load periods?

However, the entire capacity is not available during the peak load periods. The Energy Authority has estimated in autumn 2020, that 11,400 MW of Finnish electricity generation capacity (incl. peak load re-serves) will be available for the consumption peaks in winter 2020–2021.
