  • Small hydro power in india

    1. 1. Power scenario in India► Renewable energy accounts forapproximately 18% of a total214.86 GW of power generationcapacity installed in India.► Demand for power in India hasbeen increasing due to the risingpopulation, growingeconomy, and changing lifestyles.► Despite substantial capacityadditions, the power sector isstill in shortage of energy.► Peak demand shortage averagesaround 9%.Source: MNRE, CEA & Economic survey of India 201258%9%1%2%18%12%CoalGasDieselNuclearHydroRES10.2 12.3 14.4 16.82024.5FY07 FY08 FY09 FY10 FY11 FY12Growth of Renewable energy installedcapacity in IndiaCAGR 19%
    2. 2. INDIA is capable with economically useable and viablehydro potential assessed to be about 84,000 MW at60% load factor (1,48,701 MW installed capacity)56 sites for pumped storage schemes with an aggregateinstalled capacity of 94,000 MW have been identified.(source-http://www.nhpcindia.com/English/Scripts/Hydro_Potential.aspx)
    3. 3. The Size of A Power Plant• A Macro Power Plant : > 100 MW.• A Small Power Plant: 5 MW to 25 MW.• A Mini Power Plant: 500 kW to 2 MW.• A Micro Power Plant: 50 kW to 200 kW.• A Pico Power Plant: < 30 kW.

    6. 6. Methodology of HEPP Development• Site Survey: Hydrological & geological Survey.• Estimation of Potential• Regulations & Environmental Concerns• Feasible Supply• Turbine Selection• Costing and Payback.
    7. 7. Hydrological Survey: Flow Duration Curve• To measure the flow-rate vs time at a given site.• Direct Measurement of the flow rate.• The more robust option is to find out the flow-rate by workingout the volume of water that was entering the river.• This uses the rainfall data from met office.

    15. 15. HYDRO SCENARIO IN INDIAIndia is blessed with massive amount ofhydro-electric potential , ranks 5th in terms ofutilizable hydro-potential on global scenario. As per valuation made by CEA, India isendowed with economically exploitablehydro-power potential to the tune of 1 48 700MW of installed capacity.

    17. 17. Energy Map Of India
    18. 18. India is capable with hydro-potential of about 250 000 MW.In 1998, Government of India announced"Policy on Hydro Power Development" underwhich impetus is given to development ofhydropower in the country.
    19. 19.  Present installed capacity is approximately37,367.4 MW which is 21.53% of total electricitygeneration in India.The public sector has a predominant share of97% in this sector.National Hydroelectric Power Corporation (NHPC) Northeast Electric Power Company (NEEPCO) Satluj jal vidyut nigam (SJVNL)Tehri Hydro Development Corporation NTPC-Hydro are a few public sector companiesengaged in development of hydroelectric powerin India.

    26. 26. Fund RequirementDuring the 12th Plan, 25,316 MW capacityaddition appears feasible. To achievethis, funds requirement during the 11th and12th Plans would be of the order of Rs 68,924crores and Rs 82,972 crores, respectively asper the following break up….
    27. 27. CEA Report on PFSSolar PV and Hydro Integrated Power Generation• PFS on Bhakra hydro stationFindings• Hilly terrain & Dense Vegetation• Spillways is not feasible because of north facing• Rooftop of the ganguwal and kolta powerhouse ,forebay area about 2580m² is suitable• Approximately 210 kWp capacity• Some location like guest house and NangalPower house is also good for SPV plant
    28. 28. • Recommendation for Cannel top SPV systemBenefits of Integration• Space Utilization• Easy Power evacuation facility• High Power production of SPV• Reduce evaporation of Water• Power supply for Aux. consumption• Reduce Project cost
