How does the Nordic Balancing Model (NBM) impact today’s aFRR?
In the coming years, several major changes will take place regarding aFRR. These changes concern both the dimensioning—i.e., the volume requested per bidding zone and hour—and the procurement process. As we connect to the European platform for aFRR exchange, PICASSO, the basis for control signals will also change (from frequency deviation to area imbalance), and aFRR will be activated through an energy activation market ahead of the upcoming delivery period.
