Glacial collapse wipes out a dozen Nepal hydropower projects
- A glacial collapse on Aug. 26 sent an ice-and-rock avalanche crashing through roughly 40 miles of Nepal's Trishuli river valley, destroying nearly a dozen hydropower projects, the Wall Street Journal reported.
- The disaster has killed around 1,400 people overall, with more than 5,000 missing.
- The 216-megawatt Upper Trishuli 1 dam, backed by the World Bank's International Finance Corporation, was the largest installation hit, with more than 500 of its 1,400 on-site workers missing.
- Engineers said the flood swelled to 20 times the level that the Langtang Khola Hydro project was designed to withstand.
- Geomorphologists calculated the Aug. 26 ice-and-rock avalanche was roughly 10 times the volume of the 2025 collapse that destroyed the Swiss village of Blatten.
- Nepal has quadrupled installed hydropower capacity over the past decade, with more than 210 projects under construction that would expand capacity by an additional 150%, per industry estimates.
