Helsinki to become site of largest energy storage in the Nordics
Helen has launched a pilot project to test new opportunities offered by a megawatt-scale electricity storage facility, as a result of which Helsinki’s Suvilahti will become the largest electricity storage in the Nordic countries.
The significance of energy storage is growing, along with the increase in renewable energy sources, such as solar and wind power. During good weather, when a lot of electricity is produced but demand is low, it should be possible to store electricity. With intermediate electricity storage, supply can match demand more flexibly and the electricity storage facility will also stabilise the electricity grid.
Helen is the first company in the Nordic electricity market to integrate a mega-watt scale lithium-ion battery energy storage system in the electricity grid. The Suvilahti electricity storage facility will comprise some 15 000 lithium-ion battery cells that will temporarily store the energy generated by Helen’s Suvilahti power plant and the plant currently under construction in Kivikko.
Helen’s partners in the pilot are Helen Sähköverkko and the national transmission system operator Fingrid. The battery technology will be supplied by Landis+Gyr together with Toshiba. The electricity storage facility will be integrated in the Kalasatama district’s smart energy system.
