What is the cost difference between overhead and underground installations?

2025-08-13

The installation cost is often a deciding factor. While it varies greatly depending on the project's scale, location, and voltage, a common rule of thumb is that underground cable installation is significantly more expensive than overhead line installation—often by a factor of 5 to 10.

  • Overhead Costs: Primarily driven by the cost of conductors, poles/towers, insulators, and labor for stringing.

  • underground Costs: Include the cost of specialized insulated cables, extensive civil works for excavation and trenching, and a high cost for labor and specialized equipment like cable laying winches and cable trailers.
