This report examines how APEC economies are integrating resilience into energy policy, planning, and regulation amid rising electricity demand, intensifying climate risks, and rapidly evolving energy markets. Using the APEC Energy Resiliency Principles and international reference frameworks, it assesses robustness, flexibility, recovery capacity, and governance across diverse energy systems. The analysis reviews laws, strategies, grid codes and performance indicators to identify common challenges—such as growing climate hazards, expanding renewable integration, and the need for stronger system flexibility. It also highlights differences shaped by access levels, energy mixes, and market structures. The report concludes with key messages emphasizing the need for explicit resilience objectives, climate‑informed infrastructure planning, alignment between resilience and decarbonization pathways, and improved metrics to capture system performance during extreme events.
