FIGURE 50: Density and cumulative probability distribution of IRR of Equity for SF geothermalpower plant with resource characteristics: (a) Scenario 1 (27.7 MW): 300 kg/s and 240°C; (b)Scenario 2 (55.5 MW): 600 kg/s and 240°C7.3 Results for multiple resource scenarios and three power plant technologiesThe contours maps of the probability of success for an IRR of Equity greater or equal to 20%, fromthree technologies of power plant investment, are presented in this section. This kind of contour mapcan be a practical tool for decision makers in order to evaluate the profitability of success for differentexpected geothermal resources. Based on the contour lines, investors can identify the project risk fordifferent resource scenarios.7.3.1 Single flashFigure 51 shows the contour map of the probability of success (%) for IRR of Equity greater or equalto 20%, and the power plant size (MW) for an SF power plant development. The color of the contourlines is used to illustrate: black for the probability of success, and red for the power plant size. Thegeothermal resource temperature examined is between 160 and 340°C, and the mass flow rateexamined is between 100 and 1000 kg/s.In Chapter 6, Figure 43 illustrated that single-flash development had a profitable indicator for plantcapacity above 23 MW. The analysis of the data from Figure 51 suggests that the probability ofsuccess is roughly 50% for 23 MW of power plant capacity. It is important to note that there is a highrisk associated with geothermal projects. For example, 70% of the probability of success of the MARRfor equity would require a power plant size greater than 70 MW.7.3.2 Double flashFigure 52 shows the contour map of the probability of success (%) for IRR of Equity greater or equalto 20%, and the power plant size (MW) for DF power plant development. The color of the contourlines is used to illustrate: black for the probability of success, and red for the power plant size. Thegeothermal resource temperature examined is between 160 and 340°C, and the mass flow rateexamined is between 100 and 1000 kg/s.59
