Given the above data tables for wind distribution at a given site (for about a year) and the power curves, estimate the energy produced during this data gathering period (about a year) for both the red (tallest) and the light blue (2nd tallest) curves. Assume that wind speed bin 1 M/S represents hours from 0 to 2 m/s, then 3 M/S represents hours from 2 to 4 m/s, and so on. What is the average or expected power for both of these types of turbines? Assuming the taller curve turbine costs 2 million dollars and the 2nd tallest curve turbine costs 1.2 million dollars, estimate how long before the more expensive turbine has caught up with the other turbine? Assume a PPA price of $160/MWh. State any other assumptions that you might make clearly. (Neglect production tax credit, time value of money, and other such complications)
