2. History

A group of professional Engineers with extensive experience

in the field of design, construction and operation of hydropower projects, came together in 2005 to study and design hydropower projects with a intense on small and medium size projects. Later, as the energy need of the nation grew for the construction of larger projects, we went on expanding our group. To match the pace of the development, TAC Hydro Engineers was established, which then expanded into TAC Hydro Consultancy.

The total installed capacity of the Mathillo Inkhu Khola Jalbidhyut Aayojana is 33.20 MW. The design discharge is 7.24 m3/sec. The project has 4015 m length of waterway tunnel of diameter 2.8m and underground circular surge shaft of diameter 6m. Two units of Pelton Turbine each of capacity 16.75 MW is housed in underground powerhouse.


Feasibility Study and Initial Environment Examination (IEE) Study. 

(Lower Chameliya Hydropower Project) is located on the Chameliya River in the Darchula and Baitadi Districts of the Sudur Paschim Province in Nepal. It is a peaking run-off river project and is cascade project of NEA’s (Nepal Electricity Authority) Chameliya Hydroelectric Project (CHEP). The project’s headworks are situated at a catchment area of 1084 km2. With a gross head of approximately 67.35 meters and a design discharge of 36.38 cubic meters per second, the installed capacity of LCHP is 20.00 MW. The design discharge and turbine discharge for LCHP are the same as in CHEP, as it receives diverted tailrace water from CHEP.

8. Project Engineering


Detailed Engineering Design of project including Design of Access Road, Tender Document Preparation and Bid Evaluation. The Kasuwa Khola Hydropower Project is a Peaking Run-of-River (PROR) type project situated in the Makalu Rural Municipality of the Sankhuwasabha District, Koshi Province, Nepal. Located in the pristine Makalu Barun National Park, it utilizes the Kasuwa Khola, a tributary of the Arun River, and receives significant water inflow from the Hinsa Khola. With a gross head of 560 meters and a design discharge of 9.9 m3/s, the project covers a catchment area of 85.97 km2. Its 45MW capacity and PROR design enable it to supply additional power to the grid during peak demand, contributing to a reliable electricity supply.


Detailed Engineering Design, Tender Document Preparation and Bid Evaluation. The Madhya Chameliya Hydropower Project (MCHP) is a Run-of-River type project located in the Chameliya River in the Darchula district of Sudur Paschim Province, Nepal. It has an available gross head of approximately 136.26 m and a design discharge of 25.17 m3/sec diverted into two horizontal axis Francis units via 3.8 m diameter of buried steel pipe. With these parameters, the project has an installed capacity of 28.00 MW, aiming to harness the river’s energy potential for sustainable electricity generation.



Detailed Engineering Design, Tender Document Preparation and
Bid Evaluation of Transmission Line. The Madkyu Khola Hydropower Project is a run-of-river hydroelectric plant situated in the Kaski District of Nepal.
