Climate Change results in possible less frequent but more intensified storm events that include so called super typhoons. To ensure the resilience of the energy power delivery systems, this paper offers lessons learned from forensic investigations of the damaged power delivery systems from the Philippines after the 2013 Super Typhoon Haiyan. The objective is to investigate new strategies to design the power delivery systems, especially in the coastal regions, to defend against the intensified storm events brought on by climate change. A critical review of current power line system design approach, especially load design based on ASCE 7-10, is conducted. The review along with extreme loading calculations revealed limitations in current design philosophies. A design framework using a holistic approach that includes a strong backbone line system is suggested. The strong backbone line system is to be designed for extreme loading scenario with additional considerations including debris loading, wind-storm surge interactions and local geospatial condition with multiple wind directions. Preliminary design of a strong backbone system for McClellanville, South Carolina, power supply scenario is presented as a case study and is shown to be economically viable.
