Abstract-Electricity is considered as a flexible form of energy and critical resource for modern life and a vital infrastructural input for modern economic development. Now-a-days in all types of area like economies, households and companies have extensive demand for electricity which is due to industrialization, extensive urbanization, population growth, rising standard of living and modernization of the agricultural sector of a country. The scarcity of energy in rural areas of developing country like Bangladesh is acute and bears little sign of improvement for future. Energy from commercial resources accounts for only small percentage of all energy used in the domestic sector and again which is not uniformly distributed to the all peoples. Only a small number of villages have access to electricity in these modern days. Complete rural area electrification will always entail high transmission and distribution costs. Recently biomass is used recklessly. This irrational and unplanned exploitation of biomass resources is resulting in environmental degradation heavily. Bio-gas technology can be considered a partial but significant solution to electricity scarcity and also many other problems of energy which is a simple technology generally referred to as 'intermediate', and have every prospect to have an extensive use in developing countries like Bangladesh. But important fast is that, adoption of this new bio-gas technology does not only end with the construction of a plant, but also it requires some proper planning with respect to creation of social and economic acceptability apart from technological diffusion. In recent times 'single-owner' plants is very much encouraged by the Government of Bangladesh, where only a segment of population like the house having 5-6 cow, have the access to derive its benefit accordingly. But system would be much economic when larger plants can be constructed to serve a community as well as to bring a large group of population under its great benefit. But adoption of the community approach will require activities like mobilization of community supported by, awareness in building, proper supervision of credit, training among all the users regarding its operation and maintenance system and so many things. The research paper proposed a system which is able to meet the electricity requirement without taking any electricity from grid for individual house and where cow-dung generated bio-gas is used as a primary energy source for the generation of electricity.
