Langtang Project: Nepal’s first hydropower from a glacial lake


From UPSC perspective, the following things are important :

Prelims level: Langtang Microhydro Electricity Project

Mains level: NA


Langtang Microhydro Electricity Project, Nepal’s first hydropower from a glacial lake has become functional recently.

Langtang Microhydro Electricity Project

  • The Project was built three years after the 2015 earthquake-avalanche that devastated the valley, with help from the Hong Kong-based Kadoorie Charitable Foundation.
  • It has a weir and spillway at the moraine, and the water is taken through a fibre glass-insulated penstock pipe to a powerhouse that generates 100kW of electricity.
  • It seeks to provide 24 hours of electricity to 120 households and tourist lodges in Kyanjin and Langtang.

Uniqueness of the project

  • The project is the first-of-its-kind in Nepal to power a village and holds promise for other remote Himalayan valleys where the risk posed by expanding glacial lakes can be mitigated.
  • At the same time, it provides electricity to tourism-dependent families.
