This paper proposes method for generation of electricity using human waste. The human waste was subjected to anaerobic digestion in the biodigester which was taken to be the septic tank with little modification to enhance biogas production and collection. Biogas produced and collected was subjected to treatment to remove CO2 and H2S which were the major corrosive contaminants principally present in the raw biogas stream in order to prepare it as inlet gas for the gas turbine plant. Both single and combine cycle gas turbines were evaluated based on their capacities and electrical power output from unit volume of biomethane gas. FUTO NNDC Hostel with a capacity of 696 students was taken as case study. From the results, it was realised that a total biogas volume of 35 m3 was produced daily from the NDDC hostel. This gave a total biomethane volume after treatment of 22.75 m3. When this biomethane volume was used for electricity generation, it produced an electrical power of 5.21 KW per day for combine cycle gas turbine and 3.22 KW per day for single cycle gas turbine. The results on power usage reveals that the power generated from the NDDC hostel per day will serve the electrical energy needs of 626 households using a daily electrical energy of 0.2kwh if CCGT was used for power generation, and a total of 387 households using the same energy needs of 0.2kWh if single cycle gas turbine were used for power generation.
