An ultracapacitor in a hydropower plant can store and discharge electricity very quickly. It is able to meet the new and increasingly stringent requirements of the frequency containment reserve for disturbances.
My Fingrid is a central point of access for customers looking for detailed information on power outages and estimates of the locations of faults.
The disturbance in the electricity grid in Continental Europe last year showed how well pan-European collaboration can work.

Finland’s main grid has an excellent reliability of operation rating. There can be more than 350 disturbances per year, and faults are cleared swiftly. Mari Kiuru, Network Control Expert at Fingrid, answers our questions.
Fingrid, Outokummun Energia and PKS Sähkönsiirto are together realising a solution for reducing the number of outages caused to customers on long main grid lines by more than half.
