Overall, wind farms cost in the area of $1,000 per kW of capacity, so a wind farm consisting of seven 1.8-MW turbines runs about $12.6 million.
Small farm and residential turbines cost far less to build or install, but cost more per kilowatt of energy produced. The price of residential and farm turbines are based on kilowatts, and 10 kilowatts cost $48,000. You can expect to pay between $2,800 and $4,800 per kilowatt with professionally constructed turbines.The good news is there are kits that teach you how to make your own wind turbine for $200 or less.ou can expect to pay between $2,800 and $4,800 per kilowatt with professionally constructed turbines.
