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-$80,000 (or more).maller farm or residential scale turbines cost less overall, but are more expensive per kilowatt of energy producing capacity. Oftentimes there are tax and other incentives that can dramatically reduce the cost of a wind project.
1 The cost of electricity can be reported in dollars per megawatt-hour ($/MWh) or cents per kilowatt-hour (c/kWh) as commonly seen on residential electricity bills. 2  For example, $50 per MWh = 5 cents per kWh. 3  An average U.S. home uses 11,000 kWh or 11 MWh each year. The Department of Energy finds that â Among a large sample of wind projects installed in 2012, the capacity-weighted average installed cost stood at nearly $1,940/kW, down almost $200/kW from the reported average cost in 2011 and down almost $300/kW from the reported average cost in both 2009 and 2010 .â [3].
