Tropical cyclones are a leading cause of electric power outages, and the time required for power system recovery after storm damage is a critical measure of system resilience. However, systematically collected data on power supply disruptions are available for only a limited number of countries, leaving global patterns largely unexplored. In this study, we conducted the first global analysis of electric power system recovery times after 396 storms across 66 countries from 2012 to 2021, using satellite-based daily nighttime lights (NTLs) derived blackouts following storms. The median duration of blackouts detected worldwide was 4 d, with 5th–95th percentiles of 1–12 d. We found that high density urban areas had significant (P
