Figure shows that for low ORC inlet temperatures, the two optimization strategies yield nearly identical results; however, they begin to differ at higher temperatures. For example, the minimum cost strategy has a higher ORC outlet temperature than the maximum power strategy for an inlet temperature of 200°C. In this case, the cost of removing the remaining low-temperature heat is not worth the value it provides, and the geofluid is reinjected near ~70°C. Conversely, in the maximum power case, the ORC always removes the maximum possible heat from the geofluid (i.e. an ORC outlet temperature of 27°C). The lowest geofluid outlet temperature possible from the ORC is the sum of ambient temperature (15°C), cooling tower approach temperature (7°C), and minimum heat exchanger pinch temperature (5°C). When the ORC outlet temperature is this minimum value, no additional heat extraction is possible and electricity generated per unit geofluid is maximized. In Figure , the outlet temperature is greater than 27°C at inlet temperatures below 200°C for the "Max Power" case because the minimum pinch temperature difference in the heat exchanger is located between the preheater and boiler, instead of at the preheater exit (as is the case in Figure at temperatures above 200°C).
