TIUNI PLASU HYDROELECTRIC PROJECT (72 MW)

CHIEF ENGINEER’S REPORT

The socio-economic development of any State is dependent upon

availability of electrical energy which has been aptly termed as the engine of

growth. In order to accelerate the economic development of the state of

Uttarakhand bringing about social well being for its population, industrialization

and increase in agricultural and horticultural production are necessary.

The State of Uttarakhand has an identified hydropower potential of about

15000 MW. Out of this possible generating capacity, about 3000 MW have

already been harnessed. Project totaling to a capacity of about 2150 MW are

under construction and another 9264 MW are in the planning stage. The

Government of Uttarakhand recognizing the fact that the hydropower potential of

the state needs to be harnessed to the maximum in the shortest possible time for

the economic development of the state and for meeting the energy demand of

the country has accorded top priority to this sector.

The Tiuni-Plasu Hydroelectric Project is a run-of-river scheme, located in

Tehsil Tiuni, district Dehradun, Uttarakhand. It envisages the utilization of water

of river Tons, a tributary of river Yamuna to generate 72 MW hydropower,

harnessing a head of about 67 m. The project is located from geographical

coordinates 77050’20’E to 77051’30’E and 30o55’0”N to 30o57’20”N. The river

Tons originates in the glacier of Himalayas in the extreme northern part of district

Uttarkashi, Uttarakhand.

The site was identified during 1971-72 by investigation wing of the U.P.

Irrigation Department. The original scheme was prepared in March, 1983 utilizing

a gross head of 92 m by constructing a barrage at Tiuni and a power house at

Plasu. A detailed project report based on investigations was prepared and

submitted in October, 1987 having an installed capacity of 50 MW utilizing a

gross head of 95 m. Due to shifting of power house site to upstream on account


v

of high F.R.L. of Kishau Dam, a DPR of 42 MW installed capacity was prepared

in October 1992 by the Investigation and Planning Organization, U.P. Irrigation

Department, Dehradun. Subsequently the project was transferred to Uttarakhand

Jal Vidyut Nigam Limited (UJVNL), UJVNL prepared a pre-feasibility report in

August 2007 envisaging an installed capacity of 66 MW. Later on, the

development of this particular project was transferred to Uttarakhand Irrigation

Department in August 2008. The present proposal envisages a construction of

138m long barrage across river Tons and a Surface Power House of installed

Capacity of 72 MW.

The scheme would generate 423.29 million kwh in 50% dependable year

with 95% plant availability factor. The cost of the project including escalation in

cost during construction period and interest on loan amount during construction

(IDC) is estimated at Rs. 82953 lakh. The cost of generation is estimated at Rs.

3.97 per kwh in the first year and the levellised cost of generation is Rs. 3.55 per

kwh.

The perusal of the present Detailed Project Report clearly indicates that

the Tiuni Plasu HEP (72 MW) is a technically feasible and economically desirable

project for hydropower development to meet the energy requirement of the State.

TIUNI PLASU HYDROELECTRIC PROJECT (72 MW)

SUPERINTENDING ENGINEER’S REPORT

The Tiuni-Plasu Hydroelectric Project is a run-of-river scheme, located in

Tehsil Tiuni, district Dehradun, Uttarakhand. It envisages a construction of 138m

long barrage, 200m downstream of confluence of river Pabar and Tons near

Tehsil Tiuni to generate 72 MW hydropower, harnessing a head of about 67 m.

The site was initially identified by U. P. Irrigation Department during 1971-

72 utilizing a gross head of 92 m by constructing a barrage at Tiuni and a power

house at Plasu. Later the project was transferred to Uttarakhand Jal Vidyut

Nigam Limited (UJVNL) and a pre-feasibility report was prepared by UJVNL in

August 2007 envisaging an installed capacity of 66 MW. Again the development

of this particular project was transferred to Uttarakhand Irrigation Department in

August 2008.

The project, now envisages a construction of 138m long barrage across

river Tons having 8 bays. The barrage will be constructed at the place where the

bed level of river Tons is 908.00m. The length of the reservoir formed due to the

construction of the barrage will be about 1.1km with live storage capacity of the

reservoir as 0.438 Mm³

The water from the barrage will be taken to power house through two

HRT’s, each of dia 6.00 m & 2.035km length connected to two sedimentation

tanks at the end. The length of each sedimentation tank will be 360.00 m. These

sedimentation tanks will remove sediment particles upto the 150 micron. From

these sedimentation tanks, a single HRT of 7.60m dia & about 1.85Km. length,

will be constructed. A Surge Tank of 35 m dia & 28 m high is also proposed to be

constructed before carrying the water to power house through a 110m long

penstock of 4 m dia. The power house will have 3 no. of vertical Francis type

turbines, each of 24 MW capacity.

The scheme would generate 423.29 million kwh in 50% dependable year

with 95% plant availability factor. The cost of the project including escalation in

cost during construction period and interest on loan amount during construction

(IDC) is estimated at Rs. 82953 lakh. The sale price is estimated at Rs. 3.97 per

kwh in the first year and the levellised sale price is Rs. 3.55 per kwh.

The Tiuni Plasu Hydroelectric Project (72 MW) on river Tons in district

Dehradun is therefore a technically feasible, viable and eligible project for

development to meet the energy requirement of the State. The sale price of Rs.

3.55/- per kWh may appear to be on higher side at the first sight. However,

considering that energy is becoming scarcer day-by-day, the cost of energy in

the long run shall be economical. Hence, construction of 72 MW Tiuni Plasu

Hydroelectric Project is worth for consideration.

Fig. 1.2 Route Map

The route via Chakrota remains closed for a considerable period in winter season

due to snowfall. Keeping in view the above facts, it is proposed to use road route

via Koti-Meenus & Ataal for project works. In major portion of this route, the road

is only one lane wide. So, this road will have to be got widened to two lanes,

otherwise it will not be possible to transport cement, steel and heavy machineries

such as turbines etc. The widening of this road in some reaches is in progress.

TIUNI-PLASU-HEP-DPR

I-4

1.4 GENERAL CLIMATIC CONDITIONS IN THE PROJECT AREA

The climate of the catchment area is generally temperate and varies with

elevation. Fairly long and severe winter season is the chief climatic feature. It is

warm in summer, humid in monsoon and cold in winter. The climatic

classification of the area is variable from tropical monsoon, mild winter, dry

winter, hot summer to tropical upland, mild winter, dry winter, hot summer to

tropical upland, mild winter, dry winter, short warm summer. The project area is

at an elevation of about 908.00 m to 860.00 m. The mean temperature is around

20oC with maximum and minimum temperature 45oC and 2oC respectively.

However, the lowest temperature of -5o C in the catchment was also recorded. In

this river basin, the climate is tropical monsoon type with most of the rainfall

occur in the summer period i.e. from June to September due to tropical storms

and depressions originating in Bay of Bengal. The mean annual precipitation at

Rohru, Jubbal, Chopal, Arakot, Mori, Naitwar and Tiuni raingauge stations

established in the catchment are about 808 mm, 918 mm, 973 mm, 1200 mm,

4015 mm, 1209 mm and 874 mm respectively. In the higher elevation, the snow

starts accumulating from the beginning of December and reaches maximum in

January / February. The snow starts melting from March onwards which

contributes to the river flows. Generally, snow accumulation and snow melt

periods are December to February and March to May respectively. The year may

be divided into four seasons, determined by the broad climatic conditions

prevailing in the region:

a. Winter season - From December to March

b. Summer or pre-monsoon season - From April to May

c. Monsoon season - From June to September

d. Post – monsoon season - From October to November

1.5 GENERAL DESCRIPTION OF TOPOGRAPHY, PHYSIOGRAPHY AND

GEOLOGY OF THE PROJECT AREA

The entire project area has lime stone, slate, quartzite, phyllites and basic rock

intrusive grouped as the Deoban lime stone formation. The lime stone is present

downstream of Tiuni. At the barrage site thinly bedded slates and quartzite slates

TIUNI-PLASU-HEP-DPR

I-5

are exposed on both the abutments. On the right bank lies a fossil valley which

runs parallel to the present course of the river. The barrage on the right bank

would have to be founded on the pervious materials, whereas in the rest of the

length it will rest on rock.

The proposed power house site is located on the left bank of river Tons near

village Naval. Dark grey to black slates interbeded with hard quartzite with

profuse quartzites veins are exposed. Site is suitable for a surface power house.

Detailed geological investigations have been conducted by Geological Survey of

India and the report is in a separate volume.

1.6 HISTORICAL BACKGROUND OF THE PROJECT

a) Earlier proposal: The site was identified during 1971-72 by the

investigation wing of the U.P. Irrigation Department, Dehradun. The

original scheme was prepared in March, 1983 utilizing a gross head

of 92 m by constructing a barrage at Tiuni and a power house at

Plasu. A detailed project report based on investigations was

prepared and submitted in October, 1987 having an installed

capacity of 50 MW utilizing a gross head of 95 m. Due to change of

power house site to upstream on account of high F.S.L. of Kishau

Dam, a DPR was prepared in October 1992 by the Investigation

and Planning Organization, Dehradun of U.P. Irrigation Department

envisaging a surface power house located in the deep cut with 3

units of 14 MW each totaling in 42 MW. In the revised proposal, the

firm power was estimated to be 14.43 MW. The estimated cost of

the project was Rs. 132.30 crores at the price last prevailing in

March, 1992. The DPR was submitted to Central Electricity

Authority. However, the project could not be taken-up due to want

of funds.

TIUNI-PLASU-HEP-DPR

I-6

Subsequently the project was transferred to Uttarakhand Jal Vidyut

Nigam Limited (UJVNL). UJVNL prepared a pre-feasibility report in

August 2007 envisaging an installed capacity of 66 MW with gross

head of 67 m.

(b) Present Proposal: Later on the development of this particular

project was transferred to Uttarakhand Irrigation Department in

August 2008. The present proposal envisages almost the same

layout proposed in earlier proposal of UJVNL and revised proposal

of U.P. Irrigation of October 1992. However, there is marginal

increase in the installed capacity which has been due to more

rigorous analysis of the hydrology and water power studies.

1.7 NEED FOR THE PROJECT, POSSIBLE OPTIONS AND JUSTIFICATION

FOR SELECTED OPTION

The State of Uttarakhand has an identified hydro power potential of about 15000

MW. Out of this possible generating capacity, about 3000 MW have already been

harnessed. Project totaling to a capacity of about 2150 MW are under

construction and another 9264 MW are in the planning stage by the State Nodal

Agency as well as Central Government Public Sector undertakings and private

developers. This capacity does not include the small hydro potential (less than 25

MW installed capacity) which is likely to be about 500 MW.

The Government of Uttarakhand recognizing the fact that the hydro power

potential of the state needs to be harnessed to the maximum in the shortest

possible time for the economic development of the state and for meeting the

energy demand of the country has accorded top priority to this sector. As a result

thereof, a number of projects in Central Sector, State Sector and Private Sector

are being set up in the state. A policy for private sector investment in the

hydropower projects ranging for 0 to 100 MW has already been announced on

19.10.2002. There are a number of sites where hydropower project of the

capacities larger than 100 MWs can be established. To attract private investment

TIUNI-PLASU-HEP-DPR

I-7

for the development of such projects and as a sequel to the policy of 19.10.2002,

the Government of Uttarakhand has announced the State policy in this regard.

The policy for the development hydro power projects in the state have been

categorized into three categories, namely:

1. Upto 25 MW installed capacity

2. From 25 MW to 100 MW installed capacity

3. Above 100 MW installed capacity.

1.8 ALTERNATIVE STUDIES CARRIED OUT FOR VARIOUS MAJOR

COMPONENTS OF THE PROJECT AND FINAL CHOICE OF THE

PROJECT PARAMETERS

The alternate studies have been conducted to arrive at the most desirable

installed capacity which has been fixed at 72 MW. The optimization studies for

barrage height and tunnel diameter have been carried out. Similarly, the location

of the sedimentation chamber has been determined after considering various

alternative situations.

1.9 NATURAL RESOURCES OF THE STATE

The state of Uttarakhand is rich in minerals like limestone rock phosphate,

dolomite, magnesite, copper graphite, soap stone, gypsum, etc. The number of

small-scale industries here are 41,216 and there is an asset of Rs. 305.58 crore.

There are the presence of 191 heavy industries which runs on a profit of Rs.2,

694.66 crore. Most of the industries here are forest based. In the year 2003, a

new industrial policy with tax benefits for investors was started and this led to a

massive upsurge of capital investment. The State Industrial Development

Corporation of Uttarakhand (SIDCUL) has established seven industrial estates in

the southern periphery of the state, while dozens of hydroelectric power stations

are being built.

90% of the population here depends on agriculture. The total area under

cultivation in Uttarakhand is 12,61,915 hectares. To its credit the state has an

TIUNI-PLASU-HEP-DPR

I-8

excellent potential for hydropower generation. There are a number of

hydroelectric projects on the rivers of Yamuna, Bhagirathi, Ganga, Ramganga

and Sharda, generating electricity. Out of 15,669 villages of Uttarakhand 12,315

villages have been electrified.

Land utilization data show that forest cover in the State is very extensive. It is the

largest land utilization category covering almost 63% of the area of the State.

The next important category is net sown area, which covers about 14% of the

State’s reporting area. In individual districts forest area varies from a low of 23%

(Haridwar) to a high of 89% (Uttarkashi), while net sown area varies from a low of

4 to 5 percent of the total area (Uttarkashi, and Chamoli) to 63 percent

(Haridwar).

1.10 SOCIO- ECONOMIC ASPECTS INCLUDING TRIBAL, BACKWARD

AND DROUGHT AREAS

The population of Uttarakhand is 8479562. Out of which the males constitute

4316401 and females 4163161 of the total population. In the rural areas the

population is about 6309317. The decadal increase in the year 1991-2001 is

19.34%, and the population density is 159 per sq km. The sex ratio is 964 per

thousand.

Population density in the 13 districts of the State varies from a high of 612 per sq.

The people of Uttarakhand are called by the name Garhwali and Kumaoni

depending on the geographical region to which they belong. Majority of the

people here are Hindus.

As per the Census of the state in the year 2001, the population religion-wise are

grouped as below:

Hindus : 72.12 lakhs

Muslims : 10.12 lakhs

Christians : 0.27 lakhs

Sikhs : 2.12 lakhs

Budhists : 0.13 lakhs

Jains : 0.09 lakhs

Other religions and not stated : 0.04 lakhs

It seems that about ninety percent of the people are Hindus. Most of the people

who reside here belong to the upper castes. However the scheduled caste

section of the population preceded the later migrants in settling the hills. The

upper castes can be further subdivided into two Indo Aryan groups. They are:

the original Khas tribes that arrived in the hills by the Vedic era and migrants from North-Central India that arrived in the medieval period.

The distinctions between the two groups are reduced as a result of caste

mobility. The other communities of the state are Jadh, Marcha, Tolcha, Shauka,

Buksha, Tharu and the Gujjar. The Gujjar`s are mainly cattle herders. Population

of the state include people from other states as Nepal, Bengal, Punjab, Tibet etc.

the majority of the people here are Rajputs.

Majority of the people speak Hindi. Kumaoni and Garhwali dialects of Central

Pahari are spoken by the people. The tribal communities use Jaunsari and

Bhotiya dialects.

The important festivals celebrated here are

1. Kumbh Mela/Ardh Kumbh Mela that is held at Haridwar in every

1.11 LAND REQUIRED FOR THE PROJECT CONSTRUCTION – FOREST

LAND, VILLAGE LAND AND AGRICULTURAL LAND, TOTAL AREA OF

THE LAND BEING SUBMERGED

The details of land requires is stated below :

- Forest land : 56.12 Ha

- Private land : 9.2 Ha

There is no submergence of land as such as the pondage is created within the

river valley.

1.12 POPULATION AFFECTED BY THE PROJECT AND OCCUPATION OF

THE PEOPLE AFFECTED :

The total number of families to be rehabilitated is 23 only.

The number of buildings /dwelling units to be abandoned is 33 only

1.13 ENVIRONMENTAL ASPECTS

The site of barrage power house, quarries and adits etc. have been so selected

that there will be minimal loss to forest and existing plantation. Only a few trees

of general variety may have to be removed for the construction of the project

components. The loss of these plantations shall be compensated by planting,

TIUNI-PLASU-HEP-DPR

I-11

additional trees in the project area and the surrounding area as provided by the

forest department.

Since the project is envisaged as a run of the river scheme with valley storage of

very minimal quantity, no agricultural forest or habitat will be submerged.

The project site is not lying within the migratory route of the animals in the region.

There will be some disturbance to the wild life during the construction of the

project, but subsequent to construction disturbance to wild life will be minimal

and negligible.

Downstream of the proposed barrage, commercial fishing is non-existence.

However, to provide passages to the migratory fish, if any, provision has been

made for fish ladder in the barrage. The water from the fish ladder shall be

allowed to flow downstream round the year which will be of the of order of 3.3

cumec as per the terms of reference approved by Ministry of Environment and

Forests, Government of India.

The river carries substantial sediment load during the monsoon period since the

scheme is a run of the river scheme, there is no necessity for undertaking

catchment area treatment for reducing sediment flow into reservoir created by

the barrage.

The barrage shall create a small lake causing standing water which may lead to

chemical and biological changes in the eco-system due to eutrophication. Since

the depth of the reservoir is less and located in a colder environment, the effect

of eutrophication is less likely. Hence, no remedial measures are envisaged on

this account.

There will not be any serious biological impact of the lake in spreading of water

born diseases that affects human beings.

The project does involve large scale rehabilitation of affected population due to

construction of the project. Only 23 families are involved who will be rehabilitated

as per the policy of the State Government / Central Government before the start

of the construction activities.

The project on the other hand shall provide a decent picnic spot for leisure

tourist. The reservoir behind the barrage can be developed for pisci-culture which

can cause enhancement of income for the local population. The tourism activities

will also increase employment opportunities for the local population. Thus, the

project shall catalyze the local area development in a significant manner.

The environmental impact assessment and environmental management plan has

been carried out extensively and is presented in a separate volume.

1.14 INTER STATE / INTERNATIONAL ASPECTS

The project area is lying within the territorial jurisdiction of Uttarakhand State, and

the use of water being of non-consumptive use, no inter-state problem is

envisaged.

The project site is more than 100 kms away from the International border, hence

no international concerns are envisaged.

1.15 DEFENCE ANGLE, IF ANY

The project has no significance from the defence angle.

1.16 COST AND BENEFITS OF THE SCHEME

The cost of the project as per the present estimates is estimated at Rs. 56940

lakhs. The anticipated benefit of the project is 330.36 million units of energy per

year in average year.
