KATHMANDU: The Dana–Rahughat section of the 220 kV Kaligandaki Corridor transmission line in Myagdi district has resumed operation after remaining out of service for 21 days due to flood and landslide damage and erosion along the Kaligandaki River.
The Nepal Electricity Authority (NEA) has temporarily restored the transmission line using an Emergency Restoration System (ERS) tower. According to the authority, one circuit of the transmission line was energised and brought back into operation last night.
Flooding and erosion damaged four transmission towers in Pokharebagar, Annapurna Rural Municipality–6, Myagdi. Towers numbered 21, 23 and 24 were completely destroyed, while tower number 22 sustained partial damage.
The disruption had prevented around 170 megawatts of electricity generated by five private-sector hydropower projects from being transmitted to the national grid through the Dana substation. With the restoration of the transmission line, electricity generated by the affected projects can now be fed into the national transmission system.
The 220 kV Kaligandaki Corridor transmission line is a double-circuit project designed to integrate electricity generated by hydropower projects along the Kaligandaki River and its tributaries into the national grid.
The transmission line extends approximately 130 kilometres from the Dana substation in Annapurna Rural Municipality–3, Myagdi, to the New Butwal substation in Sunwal Municipality–13, Nawalparasi (Bardaghat Susta West).
With a transmission capacity of 1,200 megawatts, the line is a key component of Nepal’s electricity infrastructure, supporting the integration and evacuation of hydropower generated in the Kaligandaki basin and surrounding areas.
