4. Consider the tables below. Table 1 includes information about the fixed cost of four generating technologies, Table 2 contains information about the variable costs of the same units, and Table 3 contains information about the technical parameters of these units. Please note that OOGT stands for Combined Cycle Gas Turbine. OCGT stands for Open Cycle Gas Turbinc. O&M stands for Operation and Maintenance and WACC stands for the weighted average cost of capital Table 1: Fixed Costs of Thermal Power Plants Unit Technology Capital Cost Life WACC Fixed O&M Cost Analized [KS MW) [year] 1961 [S/MW.year] Capital Cost IKSMW year) 1 Nuclear 5333 40 7 88.750 2 Coal 40 10 35,970 360 3 CCGT 978 20 10 14,390 129 4 OCGT 974 40 10 6980 Variable Costs of Thermal Power Plants Unit Technology Variable ORM Cost Heatrale Fuel price Variable Cost (S/MWh) (MBTU MWh) (SMBTU) IS MWh 1 Nuclear 2.04 10.49 0.43 6.5 2 Coal 4.25 8.8 2.22 23.8 3 CCGT 7.05 7.81 S&S 4 OCGT 14.7 10.RS 7.81 99 4 Minimum up time Thr!
