The Nordic and Baltic system operators have together secured routines and identified eventual ambiguities in a scenario where the Baltics are disconnected from the Russian grid. In such a scenario, frequency support from the Nordic system will be needed. The Baltic TSOs have restricted the import from Russia in order not to risk a serious situation in the event of a sudden disconnection from the Russian system.

TSOs are well prepared and have earlier practiced and evaluated such a scenario as part of the long-planned preparations to synchronize the Baltics with the Central European synchronous electricity system in 2025.
