Summit Power Company Pvt. Ltd.

The Surke Dudhkoshi Hydropower Project is a renewable energy initiative aimed at producing clean electricity from the potential energy of water. Summit Power Company Pvt. Ltd. is developing this Run of River project in the frontier of Khumbu Pasanghalmu VDC, Mapya Dudhkoshi VDC and Solududhkunda RM of Solukhumbu District. The project area is accessible via the Sagarmatha Rajmarg and Harkapur-Okhaldhunga Road. However, construction of additional roads (approx. 5 km) is required to access the Headworks areas. The Headworks of the project is located almost 80m below the confluence of Lujakhola and Dudhkoshi River. The intake, connecting tunnel, gravel trap, desender basin, headrace tunnel, surge shaft, vertical shaft, underground powerhouse, and tailrace tunnel along with all constructions are proposed on the left bank of the Dudhkoshi River. A weir having a height of 10.5m and a length of 48.4m will be constructed, allowing a flow of 40.24 m3/sec from the gravel trap to the desender basin, and settled clean water will flow through a 10.50m long tunnel to the surge shaft. The water will then flow to the underground powerhouse, where it will generate 188 MW electricity with the help of a Pelton turbine. The generated electricity will be evacuated through an 18Km long 220KV double circuit transmission line at the Tingla substation. The project will use 18.85 HA of forest land. The environmental study of the project has been conducted by analyzing the data collected after observing the field study, and public consultation, key informant’s interview, household survey, etc.

Project Outcome

Increase in Power Generation: The Surke Dudhkoshi Hydropower Project will generate 188 MW of electricity, which will significantly increase the power supply in Nepal. This will not only meet the country's growing energy needs in the future but also opens up opportunities for Nepal to export renewable energy to neighboring countries.

Promotion of Renewable Energy: As a renewable energy project, the Surke Dudhkoshi Hydropower Project will promote the use of clean energy and contribute to reducing Nepal's reliance on fossil fuels, which will help to mitigate the country's carbon footprint.

Employment Generation: The construction and operation of the project will create job opportunities for Nepali citizens, which will contribute to the country's economic growth.

Revenue Generation: The project is estimated to generate NPR 6470.60 million in revenue, which will contribute to the national economy and help to fund other development projects in Nepal.

Development of Infrastructure: The project requires the construction of roads, tunnels, and other infrastructure, which will improve connectivity and accessibility in the region. This will benefit local communities and support the development of tourism, trade, and other industries.
