Penn Power installed TransGard fencing in two Mercer County (PA) substations to help deter climbing animals and protect against electrical equipment interference that can cause power outages. The fencing keeps the animals out of harm’s way and electricity flowing to customers.
The company plans to install additional animal deterrent substation fencing at other locations in Mercer and Lawrence counties over the next five years.
“Climbing animals present one of the greatest threats to substation operation and electric service reliability,” said Ed Shuttleworth, regional president of Penn Power and Ohio Edison. “A single substation outage can cost thousands of dollars in equipment damage and hundreds of man hours to repair as well as causing extended outages for customers served by that circuit. The special fencing was an economical solution to prevent these types of service disruptions in the future.”
Unlike other types of animal traps and deterrents, this special fencing completely prevents climbing animals from accessing the substation equipment and discourages them from trying again. Many climbing animals, like squirrels, have a highly developed memory that enables them to remember locations for food, warmth and shelter. With one brief contact with a fence panel, animals learn that a substation is not a welcoming location to visit and typically avoid protected substations in the future.
This fencing has proven to be successful for Penn Power’s sister utility in Maryland, which has seen a sharp decline in substation outages due to animals
