Ukrenergo explains the difference between emergency and urgent power outages in Ukraine

Emergency power outages in Ukraine are a type of emergency disconnection introduced to balance the entire energy system, while local emergency outages apply only to specific regions. Both are caused by Russian strikes on energy infrastructure. Emergency restrictions are implemented when the system needs rapid balancing due to attacks, with unknown timing and duration. Scheduled outages, lasting about 4 hours with a ±30-minute switching interval, are pre-planned for electricity deficits and allow consumers to prepare in advance. Preventive outages are ordered by Ukrenergo before potential attacks to avoid larger accidents, based on military warnings. Power is restored after the threat passes.
