There exists two separate models for the installation costs per turbine in a given wind farm. The NREL Cost and Scaling Model [13] provides a cost as a function of total rated power of the wind farm, as follows (1) C I = 127.4 2015 $ kW ∗ P r This NREL equation assumes that the wind farm is composed of 167 turbines.
