3. INTRODUCTION
Hydropower is a renewable, non-polluting and environment friendly source of energy.
Oldest energy technique known to mankind for conversion of mechanical energy to electrical energy.
Contributes around 22% of the world electricity supply generated.
Maximum benefit in minimum time.

4. HYDRO POWER PLANTS IN INDIA
First hydro power plant was constructed at Mysore in named as “sivaramudram” having capacity 4-5 MW
Second hydro power plant was constructed at Maharashtra in 1914 named “khopolo” having capacity 50 MW
Hydro power plant in India in 1947=500MW

9. THE INDIAN SCENARIO
The potential is about MW at 60% load factor spread across six major basins in the country.
Pumped storage sites have been found recently which leads to a further addition of a maximum of MW.
Annual yield is assessed to be about 420 billion units per year though with seasonal energy the value crosses600 billion mark.
The possible installed capacity is around MW (Based on the report submitted by CEA to the Ministry of Power)

Hydrologic cycle

13. HOW HYDROPOWER WORKS!
Water from the reservoir flows due to gravity to drive the turbine.
Turbine is connected to a generator.
Power generated is transmitted over power lines.

15. SIZES OF HYDROPOWER PLANTS
Definitions may vary.
Large plants : capacity >30 MW
Small Plants : capacity b/w 100 kW to 30 MW
Micro Plants : capacity up to 100 kW

17. SMALL SCALE HYDROPOWER PLANT

18. MICRO HYDROPOWER PLANT

19. CONSTRUCTION COSTS Hydro costs are highly site specific
Dams are very expensive
Civil works form two-thirds of total cost
– Varies 25 to 80%
Large Western schemes: $ 1200/kW
Developing nations: $ 800 to $ 2000/kW
Compare with CCGT: $ 600 to $800/kW

20. PRODUCTION COSTS Compared with fossil-fuelled plant – No fuel costs
– Low O&M cost
– Long lifetime

21. ADVANTAGES Environmental Benefits of Hydro
• No operational greenhouse gas emissions
• Savings (kg of CO2 per MWh of electricity):
– Coal 1000 kg
– Oil 800 kg
– Gas 400 kg
• No SO2 or NOX
Non-environmental benefits
– flood control, irrigation, transportation, fisheries and
– tourism.

22. Disadvantages The loss of land under the reservoir.
Interference with the transport of sediment by the dam.
Problems associated with the reservoir.
Climatic and seismic effects.
Impact on aquatic ecosystems, flora and fauna.

23. PROBLEMS IN HYDROPOWER PLANTS
1. huge financial requirements
2. resettlement problems
3. land acquisition
4.geological problems
5.technical problems
6.contractual problems
