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.

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.
