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.
Capital costs. A kilowatt is a unit of electrical power capacity. According to a U.S. Energy Information Administration, or EIA, report published in April 2013, the cost of building a utility-gradeâgreater than 150 MW (megawatt)âsolar power plant was $3,873 per KW (kilowatt).A 1KW power plant generates one kilowatt hour of electricity if it runs at 100% capacity for an hour.n comparison, cleaner coal-fired power plants cost upwards of $4,000 per KW, and advanced natural-gas fired plants cost $2,000 per KW. Nuclear plants are the most expensive to build at $5,500 per KW. A wind power plant, another renewable source, costs $2,200 per KW to build.
