    MainsimilarityElectricity production based on diesel

    generators

    High dependence on foreign countries

    High cost of operation Air and noise pollution

    MEDSolarprojectactuationReduce the use of fuel by using:

    PV power plants Energy transient storage systems

    Increment on power supply security Reduction on operation cost Promotion of SMEs development Increment on air quality

    4.ProposedhybridsystemsPremises:

    Take full advantage of existing equipment in considered facilities:

    Diesel generators, grid connections Distribution lines

    High modularity on integration of: PV system and Storage system Priority load management

    Solution based on commercial equipment
