Catastrophic Flood Exposes the Risks of Nepal’s Hydropower Bet

The blast of earth, water and ice that rushed through a region of Nepal knocked out more than a tenth of the country’s hydropower capacity within minutes, striking at an industry Nepal has made central to its economic future.

The floods in the Bhotekoshi and Trishuli valleys damaged or destroyed 14 hydroelectric projects, including six under construction. After the deluge on Wednesday, 431 megawatts of generating capacity had gone dark, according to the Nepal Electricity Authority — more than 12 percent of the country’s total capacity.

The toll was far greater when including projects under construction. Counting those plants, now halted or in some cases swept away, would roughly double the capacity lost. Among them was the Trishuli-1 project, where 63 Indians were rescued from a construction tunnel and more than 100 workers remain unaccounted for.

The destruction was part of a much larger human catastrophe. More than 600 people were killed, more than 2,400 remained missing, and 93,000 needed assistance.
