Eversource Installing New Transmission Lines with Helicopter

March 24, 2017
Work strengthens transmission network reliability

Eversource will be using a helicopter flying more than 80 feet above ground to pull lines through new transmission structures in the Watertown/Litchfield area in New Hampshire starting this week. Once complete, these new lines will improve system reliability by creating a new path for energy to flow between substations in the area and provide a long-term solution to the region’s increasing energy needs.

“The region’s transmission system is the backbone of the electric grid, and this important work is part of our commitment to improving system reliability,” said Stephen Sullivan, Vice President of Project Management at Eversource. “Using the helicopter to install new transmission lines greatly reduces the impact to environmentally-sensitive areas.  It also reduces the amount of time needed to complete the job, compared to conventional methods.”

This work is part of the Frost Bridge-Campville Project that began in 2016 and includes the construction of a new overhead 115-kilovolt (kV) transmission line on more than 10 miles of existing right-of-way.  This project is expected to be completed in 2018.

The helicopter flights will occur periodically beginning the week of March 20th through July in Watertown, Thomaston, Litchfield and Harwinton.  All flights are weather permitting and will take place between 7 a.m. and dusk in most areas.  The helicopter being used for the work is yellow with registration numbers 938M.
