Each TSO shall perform year-ahead ... operational security analyses in order to detect at least the following constraints:
a
power flows and voltages exceeding operational security limits;
b
violations of stability limits of the transmission system identified in accordance with Article 38(2) and (6); and
c
violations of short-circuit thresholds of the transmission system.

When a TSO detects a possible constraint, it shall design remedial actions in accordance with Articles 20 to 23. If remedial actions without costs are not available and the constraint is linked to the planned unavailability of some relevant assets, the constraint shall constitute an outage planning incompatibility and the TSO shall initiate outage coordination in accordance with Article 95 or 100 depending of the time of the year when this action is initiated.
