Why are power lines installed underground?
2025-08-16The decision to install power lines underground is a strategic choice driven by several key factors. While more expensive to install, underground power lines offer significant advantages:
-
Increased Reliability: Underground lines are protected from the primary causes of power outages, such as severe weather (high winds, ice storms, and lightning), falling trees, and wildlife contact. This makes them a more resilient option, especially in areas prone to extreme weather events.
-
Enhanced Aesthetics: By removing poles and wires from the landscape, underground lines preserve the visual appeal of residential neighborhoods, scenic areas, and urban centers, which can also increase property values.
-
Greater Safety: Underground lines eliminate the risk of accidental contact with live conductors, such as from fallen lines or vehicles colliding with poles. This significantly enhances public safety.
-
Reduced Fire Risk: In areas with a high risk of wildfires, burying power lines eliminates the potential for arcs or sparks from overhead lines coming into contact with dry vegetation, a common cause of wildfires.
