Yesterday, we successfully delivered a new project: Two 40-foot containers housing an ultracapacitor energy storage system (UCES/UGS) are now on their way to Northern Finland for the Finnish energy company Pohjolan Voima Oyj (PVO).
PVO operates eight hydropower plants with a combined production capacity of 450 MW, providing the majority of the Fast Frequency Reserve (FFR) in the Nordic power system.

To protect the service life of the turbines and ensure reliable frequency reserve capability, Pohjolan Voima Oyj (PVO) has invested in a supercapacitor-based system that will be deployed at the Kierikki power plant.
The ultracapacitor energy storage system (3 MW / 30 seconds) developed by Freqcon provides frequency control power independently and in parallel with the hydropower generators, delivering full output within 150 ms.
The two containers offer flexible operation: they can be controlled individually and each provides 1.5 MW of power. The system is also designed for expansion to 6 MW and can be extended with two additional containers.
With this project, we are supporting PVO on its path toward a stable and sustainable energy future, in line with the requirements of the Nordic power grid.
