Squirrels

Substation power outages caused by squirrels

Responsible for the greatest number of substation outages across the U.S., squirrels enter substations in search of shelter and warmth—and possess the instinct to remember the best nesting sites. Their sheer numbers make them the greatest threat to substation security. TransGard’s electric fencing barriers deter squirrels and other animals that cause substation power outages.
