In Chapter 6, Figure 44 illustrated that double-flash development had a profitable indicator for plantcapacity above 25 MW. The analysis of the data from Figure 52 suggests that the probability ofsuccess is roughly 50% for an 18 MW power plant capacity. For example, 40% of the probability ofsuccess of the MARR for equity would require a power plant size greater than 60 MW.7.3.2 Organic Rankine cycleFigure 53 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 ORC power plant development. The color of thecontour lines is used to illustrate: black for the probability of success, and red for the power plant size.The geothermal resource temperature examined is between 100 and 180°C, and the mass flow rateexamined is between 100 and 1000 kg/s.In Chapter 6, Figure 45 illustrated that organic Rankine cycle development had a profitable indicatorfor plant capacity above 25 MW. The analysis of the data from Figure 52 suggests that the probabilityof success is roughly 50% for a 25 MW power plant capacity. For example, 70% of the probability ofsuccess of the MARR for equity will require a power plant size greater than 35 MW.FIGURE 53: Contour map of probability of IRR of Equity ≥ 20%; ORC power plant61
