Phases of Construction
-
Site Preparation
The first step is clearing trees and brush. This work allows construction crews to safely build access roads and remove trees that could fall onto the power line.
-
Environmental Controls
Next, steps are taken to protect the area during construction. These may include placing mats, silt fences, and concrete washout containers for construction materials.
-
Substation Upgrades
New foundations and structures are installed, along with fiber-optic cables and new wires. Old structures are removed, and the new wires are energized. Crews use heavy equipment, including cranes.
-
Restoration
After construction, crews restore the work area and return the ground as close as possible to its original condition, unless otherwise specified in regulatory requirements or by a landowner agreement.
