Executive Summary
The 1.00 MW Neptune Top Small Hydro Project is a proposed hydro electric project located
on the Neptune Khad, a right bank tributary of the Sainj River, in Kullu district of Himachal
Pradesh, India. The proposed elevations for the project are 2175m (intake) and 1875m
(tailrace), giving a gross head of 300m for the scheme.
The project is accessible on the state road along the river Sainj from Aut-Sainj-Neuli-XXX
and then till village xxx on the right bank of Neptune Khad. The project site is upstream of
the 2.4 MW under construction Neptune SHP. The project components lay along left bank of
the khad.
The main project components include a trench type weir at 2175m ASL, intake structure,
feeder channel, desilting tank, water conductor channel, forebay, penstock, powerhouse with
switchyard at 1875m ASL (as per allotment), tailrace and ~3.0 km long 33 kV power
transmission line. Two Pelton turbine-generator units of equal capacity are proposed to be
installed at the powerhouse. The catchment area of the project is ~ 16 sq km, out of which ~2
sq km is snow fed. The gross head is 300m and the design discharge for an installed capacity
of 2 MW would be ~0.75 cumecs.
The land involved in the project is almost entirely forest land. Some private land would be
involved in the road construction or in the transmission line alignment. Road requirement
would be minimal for the powerhouse in case the lower proposed elevation for the
powerhouse is approved.
Further activities in the development of the project include feasibility report, DPR, local
clearances, Technical Concurrence, IA, forest clearance, lease of forest land, and detailed
engineering design of the scheme. In addition, financial closure of bank loan and Power
Purchase Agreement (PPA) with power purchaser would be critical steps. These are likely to
take 24 months at the minimum. The construction of the project is likely to take another 2
years time from commencement. Overall, the timelines to commercial operation would range
between 4 years to 5 years from allotment.
The hydrology of the project site is good. For a gross head of 300m, the installed capacity is
likely to be 2.0 MW, with an annual generation of 10.2 GWh (Million kWh). The PLF in
that case would be around 58%. We have used the Hydra-HP software developed by AHEC,
IIT Roorkee to predict the hydrology of the project at the intake site.
We thus conclude that the Neptune Top SHP site is attractive due to its high head, lack of
private interference and fair hydrology. The head for the scheme is on good and hence the
dependence on discharge for the given capacity is lower. This makes the components (water
conductor, penstock, machines, powerhouse, etc.) compact and hence comparatively less
expensive than a similar low/medium head scheme. The hydrology of the project site is
good and the annual PLF has been estimated to be 68%, with an estimated annual
generation of 6.0 GWh (Million kWh) for an installed capacity of 1.0 MW.

Introduction
The 1.00 MW Neptune Top Small Hydro Project is a proposed hydro electric project on the
Neptune Khad, a right bank tributary of the Sainj River, in Kullu district of Himachal
Pradesh, India.
The proposed elevations for the project are 2175m (intake) and 1875m (tailrace), giving a
gross head of 300m for the scheme. The project area for the site as seen on Google earth is
shown below.
Project components represented by red line (extended elevation)
Accessibility
The project is accessible on state roads along the Sainj River from Aut to Larji and then to
Sainj town on the banks of the river Sainj. There are large projects of NHPC (Parvati II and
III) and HPPCL (Sainj – 100 MW) on the river in the vicinity. Beyond Sainj, the road leads to
XXX and then moves along the right bank of Neptune Khad till xxx Village. The under-
construction Neptune SHP is downstream of the Village along the right bank. The Neptune
Top SHP is planned on the left bank. The road ends at the intake site of the Neptune Top
SHP. Further bridge work is underway to cross to the left bank. Road of about 0.5 km length
would be required for the proposed powerhouse at 1875m For the Intake site, additional 2.0-
3.0 km of road would have to be constructed. The project is upstream of the 2.5 MW Neptune
SHP under construction. No other projects are allotted in the upstream elevation.
Hydrology & Power Potential
The intake site for Neptune Top power project is located at an elevation of 1980m on the
Neptune Khad. The catchment area of the Khad above the intake site is ~16 sq km as
calculated from Google Earth. The highest peak is around 4300m. The Catchment area
consists of snow fed region of ~2 sq km. The rest of the catchment area is rain fed and will

provide substantial quantity of water flow for the power project as it contains dense forests.
The catchment area is shown demarcated by the thin white line.
We have used the Hydra-HP software developed by AHEC (IIT Roorkee) to estimate the
hydrology and power potential of the Neptune Top SHP.
Hydra-HP is software developed by AHEC, IIT Roorkee for prediction of hydrology and
power potential of small hydro power projects located in the state of Himachal Pradesh. For
the sake of analysis, the area of the state is divided into a grid of squares, each 1 km by 1 km
in dimensions. Thus, any catchment area is divided into squares of 1 sq km area and runoff
from each such contributing square is utilized to predict the runoff for the project. The
rainfall data for the given catchment is also utilized to provide more accurate figures for run-
off.
For this analysis, we first delineated the catchment area of the Neptune Top Intake site on
Google Earth and fed the catchment area boundary point data to Hydra-HP in the format
required. The format is as given in a table at the end of this section. Once the boundary points
are input, Hydra creates a map of the catchment area with potential run-off and other
catchment characteristics based on elevation, type of catchment and rainfall data. The
catchment area characteristics for Neptune Top SHP intake site are as shown below.

As can be seen from the images, the catchment area of the intake site is ~16 sq km. The
catchment in the higher reaches is shown in a darker blue, indicating higher contribution to
the runoff, while the catchment in the lower elevation is shown in white, indicating lower
contribution to the run-off.
Based on the catchment area characteristics, the software then develops a synthetic annual
flow regime report for the intake site. The flow regime is shown in figure below. The flow
regime report shows the probability of occurrence of a particular flow over the year.

Armed with the synthetic flow regime curve, we are now ready to calculate the power
potential of the site. For that, we need to input a few more things such as the net head, the
number of turbines proposed, the design discharge and the environmental flow. Once these
data are input, the software provides us with a configuration of the possible type of turbine
for the given head-flow combination. The Pelton turbine is found appropriate for this site.
The software then calculates the power potential of the site for the given characteristics.
We have considered the gross head of 300m and calculated the installed capacity as 2.0
MW, with an annual generation of 10.2 GWh (Million kWh). The power potential report for
the project is attached below.

Hydra software has been found to predict the generation for small hydro sites in Himachal
Pradesh with an acceptable level of accuracy. We therefore use it quite extensively for
projects where hydrology data is limited.
