3. INTRODUCTION
 Tehri hydro development corporatation was
formed to manage the dam and 75% of the
funding would be provide by federal government ,
25% by the state. Utter Pradesh would finance the
entire irrigation portion of project. In 1990,the
project was reconsidered and the design changed
to its current multi-purpose.

4. one of the first hydro electric station was commissioned at
galogi in 1907. more power station were subsequently
developed over a period of time tehri hydroelectric power
complex (2400MW), comprises the following component
 tehri dam & hydropower plant(1000MW)
 Koteshwar hydro electric project(400MW)
 Tehri pumped storage plant(1000MW)

5. HISTORY
 A preliminary investigation for the Tehri Dam Project was
completed in 1961 and its design was completed in 1972 with a
600 MW capacity power plant based on the study. Construction
began in 1978, after feasibility studies but was delayed due to
financial, environmental and social impacts. In 1986, technical
and financial assistance was provided by the USSR ,but this
was interrupted years later with political instability

6. WHY HYDROELECTRIC PLANT
 Renewable and non polluting source of energy.
 Best choice for meeting the peak demand.
 Longer useful life and help in conserving sources fossil
fuels.
 Storage based hydro-project after incidental benefits like
irrigation , flood water supply in land water.
 Help in opening up of avenues for developed of remote
backward.

Electric Overhead Travelling Crane(EOT)
Generator
Turbine Section
Governor
Draft Tube
Oil Water System

10. GENERATOR
 Water flow through
multiple gates to many
turbine-blades
generate enough
mechanical power to
rotate water turbine
coupled with
Generator through a
shaft as shown
opposite.

12. FRANCIS TURBINES
 A turbines is the vertical shaft ,Francis type ,directly
coupled to generator. The spiral casing is suitable cross
section fabricated from steel plates.

13. ADVANTAGES AND DISADVANTAGES
 The major advantage of hydroelectricity is elimination of
the cost of fuel.
 Multi-use dams installed for irrigation support agriculture
with a relatively constant water supply.
 Large hydro dams can control floods, which would
otherwise affect people living downstream of the project.
 In some countries, aquaculture in reservoirs is common.

14. DISADVANTAGES
 Due to high cost of civil engineering works , the capital
cost per KW of hydro plant is high.
Since hydro plant entails huge civil engineering works
,they take a considerably long for completion.
 hydro power generation is dependent on availability of
water. In a dry year , the power generation is very low.
