Locus Energy and Ingrid Capacity collaborate on a major 70 MW battery energy storage project in Finland, strengthening the country''s energy grid and promoting sustainability.
Transmission Grids, Capital Cost and Energy Storage are the key action priorities that stand out in Finland''s energy horizon, according to the 2024 World Energy Issues Monitor survey results.
Finland has launched the world''s largest operational sand battery in the municipality of Pornainen. The facility stores renewable energy as heat and supplies thermal
Polar Night Energy is the only manufacturer with a solid-particle storage system among the companies of the survey with a commercial project. The company from Finland promotes its
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
Why Heat Storage Matters While much of the world''s focus is on electrical energy storage, such as grid-scale batteries, more than half of global energy consumption is
Sungrow, the global PV inverter and energy storage system provider, has announced the deployment of the 60 MWh battery storage project in Simo, Finland. The
As Finland''s energy transition accelerates, one thing''s clear: the country isn''t just building storage projects – it''s engineering the template for cold-climate renewable integration worldwide.
Polar Night Energy will build a second pilot plant in southern Finland to test its power-to-heat-to-power sand battery technology. The project aims to demonstrate the system''s
With energy prices on the market fluctuating widely in Finland, even on an hourly basis, there is a growing demand for energy storage systems. Improving energy efficiency and storage will lead

The 70 MW/140 MWh BESS project will be located in Nivala, northern Finland. Set to go online in 2026, the facility will enhance grid stability, energy resilience and accelerate
While conventional battery technology dominates the energy storage landscape, innovators are exploring alternative methods. These include utilizing materials like fire bricks
This paper has provided a comprehensive review of the current status and developments of energy storage in Finland, and this information could prove useful in future modeling studies of the Finnish energy system that incorporate energy storages.
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.
Swedish flexible assets developer and optimizer Ingrid Capacity has joined hands with SEB Nordic Energy’s portfolio company Locus Energy to develop what is claimed to be Finland’s largest and one of the Nordics’ largest battery energy storage systems (BESS). The 70 MW/140 MWh BESS project will be located in Nivala, northern Finland.
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.
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.
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.
