ECONOMIC ASSESSMENT
The economic assessment of GT, CC and ISCC power plant considersLCOE to compare between them. The economic lifetime of steam power plant and ISCC are expected to reach 30 years [18], while the GT life expectancy is about 15 years, after which the replacement cost has to be considered for both ISCC and CC [17], [20]. The conventional CC is taken as the reference power plant for the purpose of comparison. The economical assumptions and data for this economic analysis are presented in Table 11.
The investor has to calculate LCOE of power plant before starting the investment which is given in the units of currency (US dollar) per kilowatt-hour ($/kWh), and calculated according to reference [16], [17] and [20].
