Aerial Tree Trimming

We use a low-flying helicopter and rotating blades to trim tree limbs from the sides of power line corridors.

This trimming method helps to significantly reduce the amount of time it takes climbing crews to conduct the work manually, and reduces the risk of injury to tree crews working in hard-to-reach areas that are rocky or have dense vegetation.
The aerial saw is suspended below the helicopter and carefully guided by the pilot. It has 10 rotating blades powered by its own auxiliary engine and measures 90 to 120 feet in length.

Upgrading Our Transmission Lines Using Helicopters

Transmission lines bring reliable electricity to millions of people and are critical to delivering clean energy.

Our contract crews are flown by helicopter to conduct transmission work, allowing for minimal impact to wildlife whilst increasing reliability.

Resilient Infrastructure

We're continuously upgrading our infrastructure for reliability, resiliency and connecting clean resources.
