In Context
- The Langtang Microhydro Electricity Project was built three years after the 2015 earthquake-avalanche with help from the Hong Kong-based Kadoorie Charitable Foundation.
About Langtang Microhydro Project.
- It costs $530,000 and 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 will be providing 24 hours of electricity to 120 households and tourist lodges in Kyanjin and Langtang.
- Benefits:
- 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, while at the same time providing electricity to tourism-dependent families.
- Risk:
- The only downside would be that most glacial lakes are at very high elevations where there are few settlements, and also the greater cost of transporting equipment by helicopter.
- But if the risk-reduction from glacial lake outburst floods is factored in, these multi-purpose projects would be cost-effective.
