What is a disadvantage of installing electrical lines underground compared to overhead facilities?

Installing electrical lines underground does have disadvantages, with increased land disturbance being one of the most significant. This process typically involves extensive excavation and grading of the land, which can disrupt the natural environment and existing landscapes. Such disturbance may lead to soil erosion, destruction of vegetation, and habitat disruption for local wildlife.

Moreover, the installation process can require significant alterations to existing infrastructure, which may further complicate land use and increase the time and resources needed for construction. While underground lines offer benefits like improved aesthetics and more resilience against weather-related outages, the increased land disturbance during the installation process poses substantial challenges that must be carefully managed.
