#3. (25) Consider two power plants with the Fixed Rate Charge = 0.1 and the following parameters Capital cost $/kW Variable cost $/kWh Capacity Factor Combined cycle 500 0.05 0.4 turbine Coal steam 2000 0.02 0.9 a) What should be the price of energy for both plants if operated separately? b) Draw on one plot the screening curve for each plant c) What is the optimal mix of two plants, i.e. for what capacity factor (and hours/yr operation) is the coal steam and the combined cycle plant more efficient? (You can do it algebraically or graphically) d) For the load duration curve on the right, Demand (MW) how many MW of power of each plant 5000 should utility have in the optimal mix? (you can do it algebraically or graphically). 1800 - - - 8760 (hours) #3.
