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

HYDRO SCENARIO IN INDIAIndia 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.
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.
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.
