There are three different ways in which the cost of a wind energy system is commonly expressed.
They are

• Cost per rated power of the turbine
• Cost per unit rotor size and
• Cost per kWh of electricity generated.

Input:
	Turbine Rated Power, PR
	Capacity Factor, CF
	Turbine Cost
	Other Initial Cost
	Annual Operation and maintainance cost
	Discount Rate, i
	Life Period, n
Output:
	Cost of one kWh of electricity, c

Turbine Rated Power, PR		kW
Capacity Factor, CF		Tk/kWh
Turbine Cost		Tk
Other Initial Cost		% of Turbine Cost
Annual Operation and maintainance cost		% of Turbine Cost
Discount Rate, i		(%)
Life Period, n		year(s)

Cost of one kWh of electricity is, c = $ 0.04 TK/kWh
