2 CONTENTS INDIAN SCENARIO NEED FOR RURAL ELECTRICATION NEED OF RENEWABLE ENERGY SOURCES FOR RURAL ELECTRIFICATION TYPICAL CONTEXT OF POWER NEEDS IN RURAL AREAS OPTIONS FOR RURAL ELECTRIFICATION IN INDIA COMPARISION OF GRID COST(Rs/kWh), PV, DIESEL HOMER APPLICATION IN PV DESIGN EMISSION ANALYSIS

3 INDIAN SCENARIO  India-World’s 4 th largest Energy Consumer  The electricity sector in India had an installed capacity of GW as on April 2013  Captive Power plant generates additional of GW  Non Renewable power plant constitute 87.55% of installed capacity  Renewable power constitute 12.45% of installed capacity  Per capita average annual consumption in India-96 kWh in rural and 288 kWh in urban areas  Domestic sector constitutes major energy demand and its consumption accounts for 60 percent of energy used. The main energy sources are coal and oil, whilst hydro, wind, nuclear and biomass provide additional sources.

4 NEED FOR RURAL ELECTRIFICATION They are located in difficult terrain areas like forests, hill areas and deserts. The number of households may range between 2 to 200, with a majority of villages having a population below % of the villages in India have a population of 500 and under and 8% of these are inaccessible. Power demand in villages is quite low due to dispersed distribution of loads. Also rural domestic consumers are mainly peak time consumers, contributing for poor load factors of

5 NEED OF RENEWABLE ENERGY SOURCES FOR RURAL ELECTRIFICATION Both the traditional energy and commercial energy are in short supply and the demand supply gap is in increase. Pressure on traditional energy resources such as wood is continuously increasing due to growing population. Heavy dependence on commercial fuels such as coal and oil as a short term measure for meeting increasing demand is alarming in view of depleting fossil fuels and pollution. Energy supply to far–off rural areas is associated with high transportation and transmission losses of about 22.4%.
