System analyses and conceptual design of solar central receiver repowering concept using molten salt (60% NaNO/sub 3/, 40% KNO/sub 3/ by weight) have been performed. Analyses have developed various repowering levels, storage capacities and solar subsystem configurations. Economic analyses support the final system selection based on minimization of plant cost with maximum displacement of oil/gas. A selected 100% repowering level of the 115 MWe existing oil/gas fired steam plant will save an estimated 342,000 barrels of oil per year for an annual savings of $5,334,000 (1980 $).
