As we approach Q4 tender season, one thing''s clear: Finland''s storage boom isn''t a flash in the pan. Whether it''s HYNN''s frost-proof batteries or GreenVoltis'' smart VPP networks, suppliers
Why Finland''s Energy Storage Tanks Are Turning Heads Globally Ever wondered how a country with long, dark winters and limited sunlight manages energy storage? Finland''s
Finland''s energy storage market is expanding, thanks largely to increasing renewable energy sources, plus regulatory adaptation being made by Fingrid, the transmission
While lithium excels at short-term electrical energy storage, sand is better suited to long-duration thermal storage, especially in cold climates. This hybrid approach—pairing wind,
products and balancing capacity in the Finnish energy system are also studied and discussed. The review shows that in r. cent years, there has been a notable increase in the deployment of
You know, when people talk about European energy storage, Germany and Sweden usually steal the spotlight. But here''s the thing - Finland''s quietly been building a world-class battery
Finland''s renewable energy storage solutions using the world''s largest sand battery cut emissions by 70% in Pornainen. The system stores 100 megawatt-hours of thermal energy

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.
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.
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.
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.
HT Finland has activated the world's largest sand battery in Pornainen, storing excess renewable energy as heat to power an entire town’s heating needs. The system cuts heating emissions by nearly 70%, using soapstone as a low-cost, long-duration thermal storage medium.
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.
