INTRODUCTION
Pre-feasibility study was conducted by NEA in 2001.
Upgraded feasibility study carried out by JICA in a period
from February 2005 to June 2007.
Installed capacity of 122 MW was identified in pre-
feasibility study and optimized to 127 MW in upgraded
feasibility study.
Installed capacity of 140 MW (Maximum) established in
detail engineering study.
Tanahu Hydropower Limited (THL) was established in 2012
as a subsidiary company of Nepal Electricity Authority (NEA)
as special purpose vehicle (SPH) to execute Tanahu
Hydropower Project.
INTRODUCTION CONT…
Project site located 150 km west of Kathmandu on Seti
River near Damauli of Tanahu District. The project is seasonal
storage type capable of supplying peak power for minimum of
6 hours daily in dry season.
Power will be evacuated through 36 km long 220 kV D/C
transmission line to New Bharatpur sub-station.
Estimated Annual energy 585.7 GWh (Primary Energy:
266.2 GWh, Secondary Energy: 319.5 GWh) for first 10 year
and estimated that it will decreased by 16% after 10 years.
Will be equipped with sediment flushing system
Construction will be started in mid of 2017 and will be
completed in end of 2021.
OBJECTIVE OF PROJECT
Objective of Tanahu Hydropower Project are:
To construct hydropower plant having installed
capacity of 140 MW
To construct 220 kV Damauli Bharatpur
transmission line
Implementation of Rural Electrification in 17
VDC of Tanahu District.
Community development program in project area
Resettlement of project affected households
