Ilmatar and a UK-based investment management company, Glennmont Partners, are building an energy storage facility near the Piiparinmäki wind farm with 41 wind turbines.
The wind farm, with a total rated capacity of 211 MW will now be supplemented by 30 MW of energy storage. The balancing power enabled by the storage makes it possible to supply electricity to the grid as the situation in the energy market turns favourable. The storage also provides tools for capacity management, both in-farm and as a service, to help manage the capacity of the national electricity grid.
