The capital cost model calculates the cost of all primary components of the power plant and then determines the total cost using multipliers that account for construction, labor, etc. This bottom-up process ensures modifications to the cost of any equipment or component can be propagated. For instance, the cost of the turbine or cooling towers is determined as a function of the thermodynamic data produced with the power cycle model. As a result, when the turbine power generation increases, or the cooling tower approach temperature increases, the cost reflects those changes.
