Public Discussion during execution of Walkover Survey

The 400 kV and 132 kV transmission lines under this project are instrumental in enhancing the reliability and efficiency of Nepal’s power transmission network. They are designed to address the increasing electricity demand in key regions, including the Budhigandaki Basin, Sindhupalchowk, Kavrepalanchok, Ramechhap, as well as the remote districts of Dailekh, Kalikot, and Jumla. Jade Consult, in collaboration with POWERGRID Corporation of India Ltd., is contributing to this effort as part of a broader initiative to strengthen and expand the Integrated Nepal Power System (INPS).

The scope of Consulting Services under the CP-2 Project was expanded through an amendment to the Principal Contract, incorporating several key components. This extension includes the Engineering and Environmental Study for the New KhimtiRakathum and Phukot–Ranchuli 132 kV Transmission Line Projects. In addition, it covers substation-related works such as the 132 kV bay extensions at New Khimti and Kavre/Ramechhap substations, as well as at Kalikot and Phukot substations. The amended scope also includes the development of new 400 kV substations at Motipur, Lamahi, Chhinchu, and New Attariya, further strengthening the national transmission infrastructure.
