THE BIG PICTURE (Infographic): Blackouts in 2025
Major power outage events in 2025 reveal a broad spectrum of reliability risks, spanning voltage instability and protection failures to extreme weather and heat-related transmission stress. Compared with recent years, which were largely characterized by weather-driven disruptions and resource-adequacy events, 2025 incidents more clearly highlight vulnerabilities in interconnected system operations, including voltage management, reactive power […]
