Exceptional Nordic activation in the aFRR energy market

On 29 March, the aFRR energy market experienced an exceptionally low level of aFRR energy activation compared to the usual level. Fingrid did not receive any aFRR control signal for Nordic frequency restoration during that day. The reason was a communication failure in the data exchange between transmission system operators, which has now been resolved.

The aFRR (automatic Frequency Restoration Reserve) energy market, is a real-time market from which Fingrid procures aFRR reserves to balance the power system. In this market, the price of aFRR energy is determined for each 4-second market period based on the real-time activation signal and the aFRR energy market bids. Fingrid has joined the European aFRR energy market platform (PICASSO).
