ADVANTAGES AND DISADVANTAGES
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.
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)
HISTORYA 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
WHY HYDROELECTRIC PLANTRenewable 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.

EQUIPMENT USED( E&M)Electric Overhead Travelling Crane(EOT)GeneratorTurbine SectionGovernorDraft TubeOil Water System
GENERATORWater 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.
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.
ADVANTAGES AND DISADVANTAGESThe 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.
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.
