Kabeli 3 Hydropower Project is a run-of-river type scheme, located in Taplejung district in Province 1 of Nepal. The entire components from intake to powerhouse area are located in Sirijangha Rural Municipality. The project has an installed capacity of 21.93 MW and will generate 130.26 GWh of energy annually. The gross head of the project is 374.10 m while design discharge of the project is 7.3 cumec. The project is located in the rocks of Lesser Himalayan zone with major lithology of gneiss, schist and phyllite.
Jade Consult had carried out detail engineering design and tender document preparation of this project. Kabeli Hydropower Company Pvt. Ltd. is the developer of this project.
The intake and powerhouse site can be reached by main foot trails from Tellok bazaar. Bhadrapur of Jhapa District and Biratnagar of Morang District have regular air flights from Kathmandu city. From Birtamod, regular vehicles are available to reach Phidim bazaar of Panchthar district. This is a part of Mechi Highway. This black-topped road continues up to Ganeshchowk of Panchthar District. From Ganeshchowk to Tharpu there is a gravel road which is part of East-West Mid-Hill Highway of Nepal. There is local gravel road from Tharpu to Phundruwa of Tellok VDC of Taplejung District with a Bailey bridge over Kabeli River in between. Up to Tellok bazar a public vehicle is available and it is possible to reach Phundruwa with own private vehicle. Phundruwa is about 6 km from Tellok bazar. From Phundruwa it is about 5 km to reach Mamankhe, the headworks site. From the Jorpul, Dovan, which is a powerhouse site, a project road is proposed to reach up to headworks site. The total length of the proposed project road will be approximately 12 km.
I was involved in this project during February 2018 – August 2019. I was responsible for site selection, activity planning of geotechnical investigation of the project, geological/engineering geological mapping of the project area and access road, rock mass characterization and classification, design of support for surface and underground excavations of project components by empirical and finite element methods using applications like Rocscience RS2 and Unwedge and construction material survey.
