By using Hybrid Optimization Model for Electric Renewable (HOMER) pro software, the process has been solved completely. The (WWTP) comprises Water Motor of 0.75kW, Reuse Pump of 1.1kW, Skimmer of 0.75kW, Blower of 11kW, Sludge Pump of 1.1kW, Ras Pump of 3kW, 2 mixers of 6kW, Drive Drum of 0.55kW, Drive Blower of 0.65kW, Drive Screen Plant of 1.1kW, Drive Horizontal screw of 0.55kW, Drive Vertical Screw of 1.1kW and Submersible Pump of 1.3kW. The region has abundant solar radiation potential with a daily average 5.19kWh/m² and average wind speed 5.43m/s. The design of the standalone hybrid system of the Waste Water Treatment Plant (WWTP) with Photovoltaic Energy Conversion System (PVECS), Wind Energy Conversion System (WECS) and Battery Energy Storage System (BESS) and the design of the on-grid hybrid system had been performed and the obtained optimum design of the off-grid was the PVECS, WECS and BESS with DG. The Cost of Energy (COE) is $0.141 and the net present cost of the system (NPC) is $150,882. The SPP is 6 year. The obtained optimum design of the on-grid was the PVECS, WECS and Grid connected with DG. The Cost of Energy (COE) is $0.0495 and the net present cost of the system (NPC) is $135,572. The SPP is 3 year. The most economic one between the two scenarios: is the on-grid.
