The purpose of this research is to produce energy simulation applications based on hybrid power plant (PLTH) bayu biru to facilitate the calculation and system analysis. Stage The making of the simulation uses the visual studio application of C # by collecting the energy data generated in the PLTH bayu biru. In PLTH bayu biru consists of two sources of energy generation that is wind energy and solar energy. Applications created on the visual studio consists of two parts namely the GUI (Graphical User Interface) and coding. In the GUI section there are two parts of data input for calculation of solar panel energy and wind turbine energy while the output in the form of graphical display and energy calculation results. For the coding is done so that the GUI display runs dynamically and produces output values and graphs. The simulation test results show the display of output and graphics values on the GUI based on solar panel input data and wind turbines.
