The significant way to support the electricity sector and encourage the consumer to use renewable resources in electricity generation in Egypt is investing energy produced from hybrid renewable sources system with the grid. A hybrid PV/wind turbine system is optimized as a core source of energy for households in Egypt. The storage battery bank and diesel unit are used as secondary energy sources. The surplus and shortage of energy are invested with the utility grid. Optimization results at interest rate of 12% indicate that cost of energy (COE) and loss of power supply probability (LPSP) when connecting PV/wind system with the utility grid are 0.024 $/kWh and zero against 0.131 $/kWh and 35.5% for gridindependent PV/wind/battery system, respectively. This corresponding to 81.7% reduction in COE. Thus, it is more economic feasibility to connect PV/wind system with the utility grid than grid-independent PV/wind/battery system.
