Feature Overhead Transmission underground Transmission
Cost Generally lower initial cost Higher initial cost due to excavation and specialized materials
Maintenance Easier to locate and repair faults Localization of faults is difficult and costly
Safety More susceptible to environmental damage (storms, ice) Safer from external factors, lower risk of public contact
Aesthetics Visible and can impact landscapes Out of sight, better for congested or urban areas
