BERLIN, Conn. (WTIC Radio)—Eversource is testing out aerial tree trimming for the first time in Connecticut using rotating blades hanging below a helicopter.
With overhanging tree limbs being one of the top reasons for power outages, Eversource is working to speed up the process of clearing out tree branches that grow too close to its transmission lines.
The helicopter "finishes the work in minutes," Eversource spokesperson Frank Poirot said. "This is work that would've normally taken up to a week, probably longer, to be done from the ground."
This new technique also reduces the risk of injury to tree crews, the chances of a power outage and the potential of any harmful impacts to the environment, Poirot said.
Depending on the area, Poirot said the trimmed tree limbs will either be left on the ground or cleared away. In landscaped or manicured areas, he explained, ground crews would move in to remove the fallen branches. In highly vegetative spots, the branches would be left to decompose into the soil.
The technique has been tested out in New Hampshire, Poirot said, though it's still in its trial stages in Connecticut.
Currently, pilots with Eversource contractor Rotor Blade are conducting overhead trimming in specific areas, such as hard-to-reach, highly vegetative or environmentally-sensitive areas, he said.
"It's under consideration for a broader application, but right now, we're trying it out," Poirot said.
With this new tool in the tool box, Poirot said Eversource will be able to better maintain safe and reliable power for its customers.
