The project will help Bangkok to ready and position itself as an ASEAN metropolis. It was planned with safety considerations, an intent to beautify the urban landscape, and to support effective legal enforcement for cases of lines and telecommunication equipment that were not installed as required on electric poles of Metropolitan Electricity Authority and Provincial Electricity Authority. The underground powerline project is divided into two phases. Phase 1 covers 39 routes with 127.3 km in distance, while Phase 2 covers 134.3 km.
