Techno-economic evaluation of various electric energy supply for rural areas Pakistan

A diagnostic study was carried out to evaluate the techno-economic viability of various electric supply sources for electrification of rural areas in Pakistan in present socio-economic conditions. The important influencing factors considered were: social needs, electric requirement and availability of energy resources. The electric requirements of model rural village were established at 20431 kw h per year. Prudent evaluations reveal that hydroelectric, photovoltaic and diesel systems are better options than an electric grid extension of more than 2 km. In order to become an economically meritorious energy source, photovoltaic system should attain cost level Rs. 100 per watt-peak of installed system. (author)
