Home or Farm Scale Wind Turbines. Wind turbines under 100 kilowatts cost roughly $3,000 to $8,000 per kilowatt of capacity. A 10 kilowatt machine (the size needed to power a large home) might have an installed cost of $50,000-$80,000 (or more).
The best estimate available for the total cost of wind power is $149 per megawatt-hour, taken from Gibersonâs 2013 report. It is difficult to quantify some factors of the cost of wind power, such as the cost of state policies.or the studies we examined, capital costs ranged from $48 to $88 per megawatt-hour, while O&M costs ranged from $9.8 to $21 per megawatt-hour. Many estimates, however, donât include costs related to the inherent unreliability of wind power and government subsidies and mandates.
