When selecting the appropriate remedial actions, each TSO shall apply the following criteria: activate the most effective and economically efficient remedial actions; activate remedial actions as close as possible to real-time taking into account the expected time of activation and the urgency of the system operation situation they intend to resolve; consider the risks of failures in applying the available remedial actions and their impact on operational security such as: the risks of failure or short-circuit caused by topology changes; the risks of outages caused by active or reactive power changes on power generating modules or demand facilities; and the risks of malfunction caused by equipment behaviour; give preference to remedial actions which make available the largest cross-zonal capacity for capacity allocation, while satisfying all operational security limits.
