National Grid Helicopters Will Begin Aerial Inspections Monday

National Grid will begin aerial inspections of all high-voltage power lines on Monday, June 8.

The inspections, which are expected to continue until mid-August, will involved helicopters flying low over Marblehead and other towns throughout Massachusetts, New Hampshire, Vermont and Rhode Island. The inspections will involve continuous infra-red imaging.

According to a police log note, National Grid’s certified contractor, JBI Helicopters of New Hampshire, will be performing the aerial inspection using its Bell Jet-Ranger helicopter fleet. The helicopters are primarily painted blue and yellow with occasional red or yellow striping.

“Safety will be the #1 priority in all areas of this work,” according to the note printed in the Marblehead police log.
