As a result, the probability distributions for the financial and economic performance indica<strong>to</strong>rs arecalculated using the Monte-Carlo method and specialist s<strong>of</strong>tware. Figure 4.8 shows, as an example, theprobability distribution obtained for the ENPV. In Table 4.34, other characteristic probability parametersare given (in thousands <strong>of</strong> Euros and percentages).Table 4.34 Risk analysis: characteristic probability parameters <strong>of</strong> the performance indica<strong>to</strong>rsFNPV(C)ENPVReference value (base case) -71,877 259,680Mean -74,353 259,842Median -71,920 260,595Standard deviation 26,339 29,640Minimum value -159,475 163,406Maximum value -82,188 360,235Probability <strong>of</strong> the parameters being not higher than the reference value -71,877 259,680Figure 4.7 Probability distribution assumed for the <strong>investment</strong> costPr. distr.Ref. value0,50,450,40,350,30,250,20,150,10,050140 150 160 170 180 190 200 210 220 230 240Incenera<strong>to</strong>r <strong>investment</strong> cost (M€)Figure 4.8 Calculated probability distribution <strong>of</strong> ENPVPunctual probabilityReference valueCentralMeanSD uppCumulated probabilityMi nimumMaximumSD lowMedian1,000,900,800,700,600,500,400,300,200,100,00150.000 170.000 190.000 210.000 230.000 250.000 270.000 290.000 310.000 330.000 350.000ENPV162
