Sanjen
Jalavidhyut Company Limited (SJCL) is a subsidiary of Chilime and was
incorporated in February 2010 as a public limited company.
SJCL has planned to
develop two new projects–Sanjen Hydroelectric Project (SHEP) having capacity of
42.5 MW and Sanjen(Upper) Hydroelectric Project (SUHEP) of capacity 14.8 MW in
Rasuwa district of Central Development Region. Both the projects SHEP and SHUEP
are running in parallel to meet the target of completion in December 2016 A.D
and June 2016 A.D respectively. The plant is planned to install in the National
Grid through a single circuit transmission line at Chilime hub located at the
Rasuwa district.
The
company will manage the debt requirement of the project from the EPF for which
tri-partite loan arrangement has been signed between EPF, Chilime and SJCL. The
equity investment will be made through 51% promoter share and 49% public share.
Chilime has 38% shareholding in SJCL. The promoter share will be raised first
then after public share.

SHEP
is a cascade run-of-river hydropower development that utilizes the water from
the tailrace of SUHEP powerhouse. Additionally, SHEP utilizes 0.5 m3/s water
from Chhupchhung Khola. SHEP is one of the attractive projects due to its low
specific investment costs and its limited environmental impacts. SHEP has major
structures viz. forebay, headrace tunnel, underground surge tank, inclined and
horizontal pressure shaft, powerhouse and tail race structures. Project
utilizes design flow of 11.57 m3/s at 40 percentile flow exceedance of long
term available river discharge and 442 m gross head to produce 42.5 MW power
and 251.94 GWh gross energy per annum. Generation voltage of 11kV is stepped up
at the switchyard by 11/132 kV transformer and 1.1 km 132 kV transmission line
connected at Chilime hub will be constructed for power evacuation.

The
project is accessible via Kathmandu-Trisuli road (72 km), Trisuli-Somdang
Highway (Pasang Lhamu Highway 72 km) and 6 km long access road up to existing
headworks of Chilime Hydroelectric Project. The access road to the power house
and headwork is constructed by the company.
Hydrology:
The
Sanjen Hydroelectric Project (SHEP) is a cascade run-of-river scheme which
diverts the tail water coming from the powerhouse of Sanjen (Upper)
Hydroelectric Project and the additional water (0.50m3/sec) from the
Chhupchhung Khola. The major headworks structure of the SHEP will be a forebay
cum intake structure. Water discharged from tailrace of SUHEP powerhouse and
the water from the Chhupchhung Khola through feeder canal system will be
collected in this forebay. There will be a simple intake structure, desander
and a feeder canal to feed water from Chhupchhung Khola which is designed to
convey 0.5m3/s of water from the intake and discharge to the forebay of the
interconnection system. Adding this flow, the design discharge adopted for SHEP
is 11.57 m3/s. The forebay is provided with side channel spillway.
