About Project
Lapche Tamakoshi Hydroelectric Project 42MW
The Lapche Khola Hydropower Project is a significant undertaking situated in the Bigu Rural Municipality of Dolakha District, within the Bagmati Province. This project, harnessing the power of the Lapche Khola River, boasts a substantial capacity of 42 MW, functioning as a peaking run-off-river scheme. The project’s hydrology is characterized by a catchment area of 644.85 square kilometers, a design discharge of 17.70 cubic meters per second, and a design flood discharge of 527 cubic meters per second for a 100-year flood event. At the heart of the project’s infrastructure is a barrage-type weir, stretching 18 meters in length, with a full supply level (FSL) of 2367.00 meters above mean sea level (amsl) and a minimum drawdown level (MDDL) of 2362.00 meters amsl. The barrage is equipped with a sluice gate measuring 3 meters by 6 meters to manage sediment, complemented by three intake points and a gravel trap system. The headrace tunnel, an essential component for water conveyance, is an inverted D-shaped structure with dimensions of 4.20 meters by 4.20 meters and a length of 2380 meters, extending to the vertical shaft, including tunnels from each settling bay. This project not only aims to provide a reliable power supply but also promises significant economic and infrastructural benefits to the local community, underscoring its importance in regional development. By integrating advanced engineering with careful environmental considerations, the Lapche Khola Hydropower Project represents a vital step towards sustainable energy solutions in Nepal.
