| Project
Profile |
| The
Baspa-II project is a run-of-the-river hydro-electric
power plant with an installed capacity of 300 MW.The diversion
barrage of the project is located across river Baspa,
one of the major tributaries of river Sutlej, at Kuppa
in Himachal Pradesh. The power house is located at Karcham,
Kinnur District, Himachal Pradesh. Water is diverted from
the barrage to the power house through a diversion barrage.
The water is conducted/passed through a head race tunnel
of about 7.95 km long and steel lined pressure shaft about
845 meters long to create a design head of 702 meters
for running 3 pelton turbines of 100 MW each. A surge
shaft has been constructed between the head race tunnel
and the pressure shaft which would be used to regulate
the flow. This Run of the river scheme does not involve
any submergence or rehabilitation and is environment friendly.

| Location
and Land |
The
project site is located about 210 Kms from Shimla. Kalka,
which is the nearest broad gauge railway station on the
northern railway about 300 Kms from the project site,
is connected to the project site by National Highway-22
(Hindustan Tibet Road).
The total land requirement for the project is about 43.58
Hectares(Ha) out of which 49 Ha is government land and
the balance 14 Ha is private land. This land mainly houses
barrage; desilting chambers; HRT reservoir area at tunnel
Kuppa; approach road to intermediate adit to surge shaft
bottom and adit to gate chamber; part area of aggregate
processing plant/quarry at Kilba’ store and office
facilities created near surge shaft/ gate shaft and power
house portal; and colony, workshop, store and office facilities
at Kuppa and Sholtu. |
| Hydrology |
The
project, being a run-of-river type Hydro-Power project,
would generate power by utilizing the water diverted from
the flow of river Baspa. The flow in the river Baspa is
contributed by several nullahs and khuds and numerous
glaciers. The catchment area is mainly in the Kinnaur
district of Himachal Pradesh, covering an area of about
967.72 sq.kms. Precipitation in the catchment area occurs
mostly in the form of snow, which is moderate to heavy
depending on the altitude. It contributes to glacier formations,
which contributes substantially to the river flows during
the period April to October. Most of the annual run off
the Baspa River is derived from glacier and snowmelt.
Water
availability at sangla, the site of the diversion barrage,
has been computed using 10 days flows for the period 1977-78
to 1992-93 and the same has been considered for the estimation
of 90% dependable year for water availability. Based on
the above data, the 90% dependable year has been identified
as the year 1981-82 and the design energy for the plant
based on the water flow in that year has been estimated
at about 1214 million units of electricity. The secondary
energy generation potential of the plant based on average
discharge for the period 1977-78 to 1992-93 is about 179
million units. |
| Evacuation
of Power |
The
power generated at Baspa would be stepped up to 400 KV
and would be evacuated by two circuits of 400 KV lines
for the power station to Jhakri substation, which is about
55 Km from the site. The transmission line from the power
station to Jhakri consisting of 121 towers has been installed
as a part of the project sub-contracted by JIL to Larsen
& Toubro.
From Jhakri the following 400 KV transmission system would
be utilized to evacuate the full output both from JHPL
(300 MW) and Naptha-Jhakri (1500MW) hydro electric projects.

| Benefits |
Development
of Hydro-Power potential in Himachal Pradesh which is endowed
with established potential of over 20,000 MW is bound
to play a decisive role in not only making H.P a power
state of the country but shall ignite multi-dimensional
development of the entire region. In addition to the accepted
benefits from all Hydro-Power projects, like generating
clean power, gainful utilization of water-a renewable
natural resource for power generation, this will help
save precious fossil fuels and entail low operation &
maintenance cost, thereby, ensuring cheapest cost of power
and success of this project as the largest Hydro-Power
project awarded to the private sector in the country.
This, in ample measures, showcases the prevailing environment
in the state conducive to such mega investment, and will
provide necessary impetus for increased participation
for overall development of the state.
The implementation of Baspa project has resulted in positive
development of the socio-economic profile in view of great
employment opportunity for close to a decade to the people
of the region in both, skilled and un-skilled category.
Additionally the company has undertaken various measures
with a view to give back to the society by providing free
medical facility to surrounding villages, building schools
etc. The company has developed various infrastructure
facilities in and around the site including number of
permanent bridges and motorable roads. Due to constant
vigil maintained by the company, road blockades, which
are a perennial problem in the area especially in winter,
are removed quickly, restoring traffic in the shortest
possible time.
While the benefit from the additional power generated
are indisputable, the financial benefits from the projects
are also immense for the Government of Himachal Pradesh
as the state is entitled to get 12% FREE power generated
from the project and there would also be additional revenue
earnings by way of direct & indirect taxes by the
sale of electricity. |
