AUGUSTA, Maine (AP) — Central Maine Power Co. has begun its spring inspections of its transmission lines by helicopter. The flights help crews spot potential problems with equipment, as well as signs of unauthorized use.
CMP, a subsidiary of Iberdrola USA, owns nearly 2,500 miles of transmission line. Along with semi-annual visual patrols and yearly infrared inspections, the utility does aerial checks when problems crop up.
The inspections also turn up unauthorized use of land along the power company’s rights of way. Spokesman John Carroll says there have been problems with people using CMP’s rights of way to dispose of old appliances, building materials and cars, and using them for ATV mud runs. Carroll says that’s bad for the environment and unfair to people who live nearby.
