Video: Why are some power lines underground?

Power lines are seen along roads, down alleys and crossing streets overhead. But some areas have power lines that can’t be seen – they lay underground.

The decisions behind whether to install overhead or underground power lines in neighborhoods and developments are complex. OPPD factors in the density of the neighborhood, accessibility and cost. Underground power lines are considerably more expensive to install – and more time-intensive to repair.

Matt Peterson will explain the difference in the video above.
