The Chilime–Trishuli 220 kV Transmission Line is a crucial infrastructural development aimed at evacuating power generated from hydropower plants located in the Chilime and Trishuli river corridors and strengthening the national grid of Nepal. The line stretches over the challenging Himalayan terrain to enhance system reliability, reduce bottlenecks in transmission, and integrate various new hydropower projects. This transmission line will play an important role in stabilizing power supply and promoting deeper energy exchange within the national network.
