a. Consider a coal-fired power plant with the total capacity of 200 kW, capital cost of $1000/kW, the fixed charge rate of 0.1/yr, the heat rate of 9000 Btu/kWh, and the variable O&M cost of 0.4 ¢/kWh. The coal cost is $1.5/million Btu. The capacity factor (CF) of operation of the plant is 0.6. What is the minimum electricity price that should be offered to the power grid? b. As mentioned above, the heat rate of the power plant is 9000 Btu/kWh (i.e., 9495 kJ/kWh). The utilized coal contains 80 percent carbon and has a heating value of 30,000 kJ/kg. Let us assume 70 percent of the CO₂ is filtered before being sent to the environment. Considering the total capacity and capacity factor of the plant, determine the annual CO₂ emissions of the plant in kg given that the molecular weight of CO2 over that of C is 44/ 12. c. Considering that the plant should pay the penalty factor of $0.1/kg. CO2 for the CO2 emission, recalculate the minimum electricity price that should be offered to the power grid.
