Svk will adjust the safety margin (RM) on selected critical grid elements in accordance with the Nordic CCM Article 3.
The change means that FRM values change from 5-10% of the maximum capacity of the grid elements to 3-12% based on operational experience after Go-Live on 31 October 2024 and methodological calculations for the safety margin. New critical grid elements will get a default FRM of 10 % of Fmax. These new safety margins ensure adequate risk levels for operational security. The market impact is considered to be limited as a consequence of the simultaneous discontinuation of the daily IVA application that Svk have performed since November 2024. The change will be implemented in the flowbased calculation from EDD 25.02.25.
Svk aims to continuously monitor and update the FRM values according to the Nordic CCM. We are closely following the results from the flowbased market coupling and gaining operational experience. We are also continuously improving our tools, models and data.
In addition, Svk is continuously updating IVA values to manage risk. With the current flows, the desired flows can be controlled using IVA on 7 of the 33 CNECs, marked in green in the image below.
The graph below shows the new FRM levels for the 33 critical grid elements:
