6. Information on exact operational security limit(s) that are expected to be violated in the absence of curtailment:

The reduction of NTC FR->CH and CH->DE is due to a combination of planned outages that seems critical according to our studies.

In particular, the planned outage 220kV Hauterive-Mühleberg will continue, with the planned outage 220kV Botterens-Mühleberg in combination.

7. Why alternative measures are not sufficient to avoid the expected violation of operational security limit(s)?

The planned outage 220kV Hauterive-Mühleberg was already highly challenging in the past weeks (topological remedial actions exhausted, lack on Redispatch / countertrading potential and N and N-1 overloads on TSO and DSO level). We expect an even more challenging situation with the 2nd line in planned outage.

The cancellation of planned outage have been considered, but is also very challenging for our partners
