A closer look at animal-caused outages at substations
BY BILL REICHARD, TransGard Systems
Every year, squirrels, raccoons, snakes, and other climbing animals cause substation outages across North America. According to a 2010 University of Minnesota study, the resulting estimated cost to electric utilities is between $15 million and $18 million per year. However, when commercial entities and consumer frustration are taken into consideration, the overall cost of these outages to electric utilities can cost the...
