Building resilience into the grid: resilience metrics and standards for transmission systems

This report outlines metrics and standards to assess, quantify, and enhance the resilience of transmission systems, building on previous work on power sector resilience. Power transmission systems are becoming increasingly vulnerable as climate change intensifies extreme weather events and amplifies system-wide risks.

As critical infrastructure spanning long distances and multiple hazard zones, these systems are particularly exposed to disruptions that can trigger widespread social and economic impacts. The report emphasizes the importance of developing harmonized approaches to measure and strengthen resilience, ensuring that infrastructure can better withstand and recover from climate-related disruptions.
