Power Outage Causes

Contact With Trees, Birds and Other Wildlife Affecting our Facilities

Likely seasons: Spring, Summer

Large trees, birds and other wildlife such as crows and snakes, or wires used for bird nesting may come into contact with electric wires, which can cause power outages.

Examples of electric wire contact accidents caused by trees and bird nests

Wind and Rain Damage

Likely seasons: Summer, Autumn

Flying objects or falling trees due to strong winds, landslides and similar can cut electric wires or cause electric poles to collapse, resulting in power outages.

Particularly in the event of a typhoon, tin roof sheeting, signboards, covering sheets, television antennas, etc. may be scattered by strong winds and come into contact with electric poles and wires, resulting in power outages. Please take measures in advance, for example, by properly fixing objects when strong rains or high winds are forecast to avoid such incidents.

If you encounter a broken electric pole or dangling electric wires, be sure to keep a safe distance and never touch anything in order to avoid severe risk of electric shock.

Example of toppled electric pole as a result of typhoon or flooding

Lightning Damage

Likely season: Summer

Lightning can destroy insulators that separate electric wires from the ground, resulting in power outages.

Example of insulator damage by lightning

Snow Damage

Likely season: Winter

Accumulated snow can cause trees to collapse and contact electric wires, resulting in power outages.
