just explain (d )

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.
d. Suppose the power grid is not interested in the new offered price by the plant. Does it
make sense if the plant operator decreases the CF of the plant to address this issue? Why
/ Why not?
