Power scenario in India

► Renewable energy accounts for approximately 18% of a total 214.86 GW of power generation capacity installed in India.

► Demand for power in India has been increasing due to the rising population, growing economy, and changing lifestyles.

► Despite substantial capacity additions, the power sector is still in shortage of energy.

► Peak demand shortage averages around 9%.

Methodology of HEPP Development

• Site Survey: Hydrological & geological Survey.• Estimation of Potential• Regulations & Environmental Concerns• Feasible Supply• Turbine Selection• Costing and Payback.

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 working

out the volume of water that was entering the river. • This uses the rainfall data from met office.

HYDRO SCENARIO IN INDIA

India is blessed with massive amount of hydro-electric potential , ranks 5th in terms of utilizable hydro-potential on global scenario.

As per valuation made by CEA, India is endowed with economically exploitable hydro-power potential to the tune of 1 48 700 MW of installed capacity.

Basin wise assessed Production

Energy Map Of India

India is capable with hydro-potential of about 2

50 000 MW.In 1998, Government of India announced

"Policy on Hydro Power Development" under which impetus is given to development of hydropower in the country.

Present installed capacity is approximately 37,367.4 MW which is 21.53% of total electricity generation in India.

The public sector has a predominant share of 97% 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 companies

engaged in development of hydroelectric power in India.

Hydropower Project under 12th Plan

Fund Requirement

During the 12th Plan, 25,316 MW capacity addition appears feasible. To achieve this, funds requirement during the 11th and 12th Plans would be of the order of Rs 68,924 crores and Rs 82,972 crores, respectively as per the following break up….

CEA Report on PFS Solar 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 power house

,forebay area about 2580m² is suitable • Approximately 210 kWp capacity • Some location like guest house and Nangal

Power house is also good for SPV plant

• Recommendation for Cannel top SPV system Benefits 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
