Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program, and a method for simulating performance of a power plant using predefined power plant models. In example embodiments, the method may include receiving user input specifying a power plant type from a plurality of power plant types. A predefined power plant model corresponding to the user specified power plant type is then accessed from a repository of predefined power plant models. A simulation is then performed using the predefined power plant model, and a report that summarizes the simulation is then generated and presented.
