JCP&L's transmission lines are patrolled at least twice each year. The patrols typically take 12 – 15 days to complete, depending on weather and other conditions and scheduling requirements. Local law enforcement agencies will be notified before the helicopter inspections take place.
During the inspection process, helicopters will hover low in areas near substations and transmission lines. When an issue is identified, a notification, along with a photograph, is forwarded to the appropriate operations area so the repair can be made.
The aerial transmission line patrols are part of JCP&L's $251 million investment in 2014 to expand and strengthen its infrastructure to enhance reliability of service.
