Figure 8.
The image shows a cumulative probability plot with net present value on the horizontal axis in million pounds from negative 60 to positive 50 and cumulative probability in percent on the vertical axis from 0 to 100. The curve remains near 0 percent for strongly negative values, begins to rise slowly around negative 20 million pounds, and increases steeply between about negative 5 and positive 20 million pounds. The curve crosses around 50 percent near approximately 8 to 10 million pounds and then gradually flattens. It approaches nearly 100 percent by about 30 to 40 million pounds, indicating a high probability of positive net present value above this range.Results of Monte Carlo analysis for NPV showing the percentage of 20 000 simulations in which the geothermal solution resulted in a positive or negative NPV
