At the present, the problem of fresh water shortage faced by most countries is a result of consumption increase and population growth. Desalination technologies improve water quality, greatly reduce water shortage problems, and improve quality of life and economic status. Conventional desalination is based on fossil fuels, however, causing it to be Unsustainable. Desalination based on renewable energy such as solar, wind sources can prove to be a viable alternative to conventional desalination. A desalination unit powered by renewable energy sources is a promising solution for this problem. This paper presents the optimal sizing of the renewable energy power system for Reverse Osmosis desalination system at Mersa Matrouh. The optimization software used in this analysis is the Hybrid Optimization Model for Electric Renewable (HOMER). The software used to evaluate the different possible configuration options for supplying the electrical load. This includes sizing, simulation and the economic study of the system. Three power system were considered, A PV--Wind -Battery system; Wind-battery system; and stand- alone PV system. A PV--Wind -Battery based power system is economically more practicable with a minimum total NPC of $455.034and a minimum COE of $.327/kWh than others systems.
