The environmental impact of using conventional thermal energy sources for generating electricity and fossil fuel’s depletion fear are two major factor pushing world towards alternative energy resources. Pakistan is blessed with high potential of solar energy but hight initial cost and unpredictable nature of solar energy makes it uneconomical. Because of the shortfall and due to the bad geographical location, most of the rural areas in Pakistan have no access to central grid.Although some of the remote community is served by the local fuel generator for just a couple of hour at night, but increasing rate of fuel is issue which makes this system non-economical and also have harmful effect on the surrounding to emit carbon dioxide and carbon mono oxide gases. To decrease dependency on hydrocarbon base generator and cope the unpredictable nature of Photovoltaic (PV) system, an off grid hybrid solar-gas generator with battery storage is presented in this research work for the electrification of rural areas of Pakistan. Purpose of this research work is to model optimize and stable system with minimum net present cost and low cost of electricity using HOMER software.
