The Problem with Birds in Substation Outages

Birds have been a problem for electrical substations since the first power distribution systems were built. The elevated components of substations create ideal perches and overhangs for birds to nest and find safety. Critical electrical substation design principles now include deterrent elements for avian safety.

Unfortunately, by choosing substations as their home, birds risk injury and death, and cause equipment damage and significant expense in several ways:

Bridging: Wingtip contact, or "bridging," involves the accidental...
