Floods in Nepal’s Bhotekoshi and Trishuli valleys damaged or destroyed 14 hydroelectric projects, including six under construction, taking 431 megawatts offline, according to the Nepal Electricity Authority. The shutdown represents more than 12% of the country’s total hydropower capacity, while including unfinished projects would roughly double the losses. At the Trishuli-1 project, 63 Indians were rescued from a construction tunnel and more than 100 workers remained unaccounted for. The infrastructure damage accompanied a broader disaster that killed more than 600 people, left more than 2,400 missing and required assistance for 93,000. The destruction has highlighted the exposure of Nepal’s plan to use Himalayan rivers to become a major producer and exporter of renewable electricity, a sector that has attracted companies from India, China and elsewhere. Puspa Sharma, a Nepali research fellow at the Institute of South Asian Studies at the National University of Singapore, said Nepal faces two important risks.
