Abstract: This paper summarizes a joint planning study completed in December 1988 on the economic potential of pumped-storage development. The study was unusual in water development investigations in that it specifically addressed the value of power from the utilities' viewpoint. It utilized a generation system expansion model, the Electric Generation Expansion Analysis System (EGEAS) program developed by the Electric Power Research Institute (EPRI). The model tracked the dispatch of the utilities' power plants, developed expansion plans with, and without, pumped storage using a least-cost optimization routine, and estimated the associated revenue requirements for the plans. The economic effects of pumped storage were then measured by analyzing the difference in system costs for the expansion plan with, versus without, pumped storage.
