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.
Using the new numbers, he finds that solarâs net cost is lower: $158,800 per MW per year, compared with coal. That is an improvement of $30,000 per MW per year, though it is still a net cost. In the original study, wind energy cost $25,300 per MW per year more than coal.With the new figures, the net costs become net benefits: $31,200 per MW per year cheaper than coal.n the capital cost of wind, Dr Lovins again cites the US Department of Energy, in this case its Wind Technologies Market Report, which calculated the weighted average capital cost of 118 wind projects in 2012 to be $1,940/KW. Dr Frankâs again uses the EIA, whose figure is $2,213/KW. That is 14% higher, not 100% higher.
