FIGURE 42: Allocation of funds for: a) Scenario 1 (27.7 MW): 300 kg/s and 240°C;b) Scenario 2 (55.5 MW): 600 kg/s and 240°C6.5.1 Single flashFigure 43 shows the contour map of IRR of Free Cash Flow to Equity (%), and the power plant size(MW) for a single-flash power plant development. The color of the contour lines is used to illustrate:black for the IRR of FCFE, and red for the power plant size. The geothermal resource temperatureexamined is between 160 and 340°C, and the mass flow rate examined is between 100 and 1000 kg/s.For single-flash power plants, the results of IRRs of FCFE for multiple power plant sizes suggestprofitable indicators for specific geothermal resource temperatures and mass flow rates. From Figure43, it is possible to conclude that in order to achieve profitable indicators, a resource temperaturegreater than or equal to 280°C demands a mass flow rate lower than or equal to 150 kg/s; this meansroughly 21 MW or less capacity. A resource temperature greater than or equal to 240°C demands amass flow rate lower than or equal to 230 kg/s; this means roughly 21 MW or less capacity. Aresource temperature greater than or equal to 200°C demands a mass flow rate lower than or equal to400 kg/s; this roughly means 23 MW or less capacity. Finally, a resource temperature equal to 160°Cdemands a mass flow greater than or equal to 900 kg/s; this roughly means 30 MW.6.5.2 Double flashFigure 44 shows the contour map of IRR of Free Cash Flow to Equity (%), and the power plant size(MW) for a double-flash power plant development. The color of the contour lines is used to illustrate:black for the IRR of FCFE, and red for the power plant size. The geothermal resource temperatureexamined is between 160 and 340°C, and the mass flow rate examined is between 100 and 1000 kg/s.51
FIGURE 43: Contour map of IRR of FCFE from single-flash power plantFor double-flash power plants, the results of IRRs of FCFE for multiple power plant sizes suggestprofitable indicators for specific geothermal resource temperatures and mass flow rates. From Figure44, it is possible to conclude that in order to achieve a profitable indicator, a resource temperaturegreater than or equal to 280°C demands a mass flow rate lower than or equal to 130 kg/s; this meansroughly 20 MW or less capacity. A resource temperature greater than or equal to 240°C demands amass flow rate lower than or equal to 200 kg/s; this means roughly 20 MW or less capacity. Resourcetemperatures greater than or equal to 200°C demand mass flow rates lower than or equal to 350 kg/;this roughly means 24 MW or less capacity. Finally, a resource temperature equal to 160°C demands amass flow greater than or equal to 800 kg/s; this roughly means 30 MW.6.5.3 Organic Rankine cycleFigure 45 shows the contour map of IRR of Free Cash Flow to Equity (%), and the power plant size(MW) for an ORC power plant development. The color of the contour lines is used to illustrate: blackfor the IRR of FCFE, and red for the power plant size. The geothermal resource temperatureexamined is between 100 and 180°C, and the mass flow rate examined is between 100 and 1000 kg/s.For organic Rankine cycle power plants, the results of IRRs of FCFE for multiple power plant sizessuggest profitable indicators for specific geothermal resource temperatures and mass flow rates. FromFigure 45, it is possible to conclude that in order to achieve a profitable indicator, a resourcetemperature greater than or equal to 180°C demands a mass flow rate lower than or equal to 250 kg/s;this means roughly 15 MW or less capacity. A resource temperature greater than or equal to 140°Cdemands a mass flow rate lower than or equal to 650 kg/s; this means roughly 16 MW or lessercapacity. A resource temperature greater than or equal to 130°C demands a mass flow rate lower thanor equal to 900 kg/s; this roughly means 18 MW or less capacity.52
