|Abstract:||The current model for electricity generation and distribution in Ethiopia is dominated by centralized power plants typically based on hydro power resource. Most of the substation in the country are old and needs upgrading. The construction of high rise buildings and industrial zones create an overloading on the existing substations, this problem can be solved by constructing new substation, upgrading old ones and using distributed generation (DG) systems. DG technologies often consist of modular and renewable-energy generators. By connecting to local distribution networks, energy is produced and consumed closer to the source of generation. This research is about using the waste to energy technology to generate green power for BOLE LEMI INDUSTRIAL ZONE (BLIZ) and a clean environment for the surrounding. A DG system is designed using biogas from the waste disposal pond KOTEBE Sewage Treatment plant (KSTP) at a close proximity ,around 0.3km ,from the BLIZ and a waste from wet room of the industrial shades as a renewable resource. It is discovered that a total of 66.45MWh/day electrical energy can be generated from the two resources and using only the resource from the KSTP a total of 36.057MWh/day electrical energy can be generated. Two methods of connection of the DG system is studied, HOMER optimization and RETscreen clean energy software are used to select the method of connection. And the waste to energy DG system connected to the grid is found to be economically feasible with LCOE $0.023/kWh .The DG system increases the reliability of the power system for the Bole Lemi substation (BLSS) and as a result of the biogas generation the odor pollution will be reduced and the environment for the surrounding will be clean.|
