Abstract

An energetic model for a hybrid solar–geothermal electric power plant (HSGEPP) is developed to explore the extent to which solar thermal resources can extend and enhance marginal and declining geothermal fields. The model is developed and presented to allow replication in a 4th-year solar engineering thermal design course. The model is applied to a HSGEPP being developed in Turkey, and simulations are run using a typical meteorological year formatted data set. The solar fraction ( f s) of the HSGEPP is equal to the fractional decrease in the geothermal resource usage. The increase in annual f s with the collector field’s solar multiple (M s) is linear up to approximately f s = 0.25 for M s = 1.25, after which the rate of increase in f s begins to decay and f s approaches 0.37 for M s = 5. For M s = 1.25, the monthly solar fraction ranges from 0.05 in December to 0.43 in July.
