After repairing damage from the two worst power outages in Kentucky history, E-On U.S. says it’s unlikely it will bury power lines to prevent future damage from falling trees.Vice President of Energy Delivery Chris Hermann says the process of burying lines is expensive and complicated, given the number of other companies that use utility poles for infrastructure.“To go into existing urban areas and try to take all of the utility lines, phone, cable, LG&E off of the polls, it’s just terribly, terribly expensive," he says.Herman says utility companies are burying lines in new developments.
