Activated frequency containment reserve for normal operation (FCR-N) is published hourly one hour after the hour in question, for example the value for hour 07-08 is published at 9 o'clock.
FCR-N is the frequency containment reserve used in the Nordic synchronous system that aims to keep the frequency in normal frequency range between 49,9 - 50,1 Hz.
Activated FCR-N volume (MWh) is calculated on the basis of the frequency in the Nordic synchronous system.
Value is activated net energy. Positive value means that the frequency has been in average below 50,0 Hz during the hour, and reserve has been activated as up-regulation. Respectively, negative value means that the frequency has been in average above 50,0 Hz, and reserve has been activated as down-regulation.
