NEA has identified load centers in the Middle-West Terai region and the need to enhance transmission capacity and reinforce substations. Most load centers are within 6 to 40 km of the Gandak substation and the proposed 220 kV line. The 220 kV multi-circuit lines will serve as the backbone for future power transmission in the region, with the Gandak–Nepalgunj line spanning over 330 km along Hulaki Rajmarga.

ChesCo is providing Consulting Services for Detailed Engineering Study for the project.
