In order to improve the distribution system, the Nepal Electricity Authority decided to lay the cable underground and remove overhead lines.

The underground cable project, funded by the Government of Nepal and the Asian Development Bank, seeks to meet the growing energy needs of the valley and is deployed underground and automated through the transmission network, using overhead insulated cables and smart meters to improve the capacity and reliability of distribution networks.

According to the announcement of the tender, the international public tender will be in accordance with the Asian Development Bank "single-stage dual-envelope tender procedures", interested bidders must be in two envelopes to submit technical and financial proposals. Technical bids will be held on September 20 when the bidders will be present at the meeting and the financial tender will remain sealed and unopened. In accordance with the procedure, only the financial tender of the technically qualified bidders will be opened.

Nepal Electricity has been considering the use of horizontal deployment of power grid system to lay the underground cable, so the damage caused by the road smaller. By drilling a pit in one place, the power lines can be deployed up to 100 meters. Once the project is completed, the road will be immediately poured into the asphalt road. According to the Nepalese Electricity Authority, the main reason for removing existing overhead lines and deploying underground cable systems, in addition to increasing capacity, is to improve the reliability of the distribution system. Kulman Ghising, general manager of the Nepalese Electricity Authority, said: "The existing power distribution system is very fragile, although the power supply is sufficient but often lead to a sudden power outage.

The existing distribution network in the Kathmandu Valley can not support more than 400 megawatts of load. The Nepal Electricity Authority is planning to upgrade the distribution network to support up to 2000 megawatts of load. "Laying down the underground cable and building a new substation will enhance the load capacity of the distribution network," added Ghising.

In the second phase, the Nepal Electricity Authority plans to use underground cables to replace the Rhone Park distribution center lines, and then gradually replace the entire valley of the distribution system. In addition to laying underground cables, the bureau is also preparing to build three 132-kilovolt substations in Phutong, Mulpani and Chapagaun to increase the capacity of the valley's distribution system.
