ABSTRACT
Improving the resilience level of a critical infrastructure is vital to face crises and ensure its proper functioning. This paper describes the methodology followed to gather information for developing a methodology to assess the resilience level of Red Eléctrica de España (REE), which is the company responsible for the transmission and operation of the electricity system in Spain. The process was based on the three units of analysis of a crisis: peak of the crisis, lifecycle of the crisis, and learning process among crisis. In the peak of the crisis we identified the impact variables that allow to characterize a crisis, and the main key stakeholders. In the lifecycle of crisis, we analyzed how the preparation and prevention activities affect the response and recovery. Furthermore, a CIs’ interdependencies analysis was carried out. Finally, the last step focused on understanding how the CI learns between one crisis and the next one.
