A modular system for decision-making support in generation expansion planning (SUPER)

A computer system for generation expansion studies (SUPER) is introduced that in addition to traditional least cost plans produces minimum risk strategies in the presence of several uncertainties, for example, in demand growth. Signals are provided that allow a utility a proper evaluation of cogeneration options and proposals by IPPs (Independent Power Producers). DSM alternatives compete with more traditional supply options in conforming adequate expansion alternatives. Hydro uncertainties are properly modeled. Interconnection lines can be expansion options. Financial and environmental impacts are evaluated and reported. SUPER has a modular structure, a relational database and a graphic user interface (GUI). Extensive experience exists using SUPER in generation expansion studies for all types of power systems.
