    ABSTRACT: A hybrid energy system in the form of the Object structure is the pattern for the structure of options in the evaluation of a hybrid system. The Object structure is defined as: Hybrid Energy System {[production (solar, wind, biomass, natural gas)] [utilization(electricity, heat, hydrogen)]}.In the evaluation of hybrid energy systems only several options are selected to demonstrate the sustainability assessment method application in the promotion of the specific quality of the hybrid energy system.In this analysis the following options are taken into a consideration:1.Solar photo-voltaic power plant (PV PP), wind turbine power plant (WTPP) biomass thermal power plant (ThSTPP) for electricity, heat and hydrogen production.2.Solar PV PP and wind power plant (WPP) for electricity and hydrogen production.3.Biomass thermal steam turbine power plant (BThSTPP) and WPP for heat and hydrogen production.4.Combined cycle gas turbine power plant for electricity and hydrogen production.5.Cogeneration of electricity and water by the hybrid system.The sustainability assessment method is used for the evaluation of quality of the selected hybrid systems. In this evaluation the following indicators are used: economic indicator, environment indicator and social indicator.
