A standalone hybrid PV/ wind energy system is proposed to be used to continuously power a submersible water pump from a selected well out of 55 production wells located at the Disi aquifer, South of Jordan. Each of these wells has a continuously-operating water flow rate of 288 m3 /h. Excess energy, if any, is to be stored in the form of a pumped water storage at the ground level near the well. Solar radiation and wind speed data for Al-Mudawara border meteorologicalstation, which was taken as a representative of the Disi water aquifer were collected and analyzed. Energy analysis was monthly made on the basis of average daily available energy. The performance of three PV/wind power plant scenarios was analyzed through the study of the underground water pumping wells using Life Cycle Cost (LCC) method. It was found that, for one scenario, the hybridization of a 16.5 MW is produced by PV power plant and 27.5 MW by wind power plant at Al-Mudawara site is the optimal scenario which is economically and technically feasible. It was found that the storage energy covered the load after implementation of the proposed project, the cost of 1 kWh of energy produced was estimated to be 0.16 $/kWh., and the system payback period was 4.5 years.
