The rotor blades of a wind turbine are the second most expensive part of the turbine, costing 22% of the total.
This technical report describes a detailed blade cost model for wind turbine blades in the range of 30 to 100 meters in length. The model estimates the bill of materials, the number of labor hours and the cycle time, and the costs related to direct labor, overhead, buildings, tooling, equipment, maintenance, and capital.
On average, wind turbines cost about $1 million per MW, or around $2 million to $4 million each. Larger offshore wind turbines can cost tens of millions of dollars. The largest wind turbine to date, which has a capacity of 12 MW, costs $400 million to manufacture and install.
According to WindEurope, the tower of a wind turbine is the most expensive part of a turbine. It costs 26.6% of the total. The rotor blades of a wind turbine are the second most expensive part of the turbine, costing 22% of the total. A National Renewable Energy Laboratory (NREL) report estimates utility-scale blades cost $150,000 or more.
The Breakdown of Initial Wind Turbine Costs. $2.6 – $4 million per average-sized commercial wind turbine. Typical cost is $1.3 million per megawatt (MW) of electricity-producing capacity. Most commercial wind turbines have a capacity of 2-3 MW, but offshore turbines can be as large as 16-18 MW.

6 FAQs about [Are wind turbine blades expensive ]
How much does a wind turbine blade cost?
The total cost of a wind turbine blade is estimated at $154,090.40. This cost breakdown is detailed in Table 26 and Figure 4 of the 'A Detailed Wind Turbine Blade Cost Model' document.
How much does a wind turbine cost?
The typical wind turbine is 2-3 MW in power, so most turbines cost in the $2-4 million dollar range. Operation and maintenance runs an additional $42,000-$48,000 per year according to research on wind turbine operational cost. See the National Renewable Energy Laboratory’s website for the most recent (December 2022) Cost of Wind Energy Review.
What is the most expensive part of a wind turbine?
Tower – steel or concrete support for the moving parts of a wind turbine. According to WindEurope, the tower of a wind turbine is the most expensive part of a turbine. It costs 26.6% of the total. The rotor blades of a wind turbine are the second most expensive part of the turbine, costing 22% of the total.
How much does a 12 MW wind turbine cost?
The most powerful 12 MW wind turbine costs up to $400 million to manufacture and install. Costs for utility-scale wind turbines can be broken down into three categories: manufacturing, transport and installation, and operations and maintenance. Researchers are constantly working to drive down the costs.
How many blades can a wind turbine produce a year?
This model imagines a wind turbine factory producing 1,000 blades per year. However, users can easily edit this value to represent their specific needs in the model for a wind turbine blade cost.
Why are wind turbines so expensive?
The values are based on typical wind turbines in use today. On the other hand, newer wind turbine technologies, such as carbon fiber, are more expensive. Engineering designs that eliminate the need for certain turbine components — such as a transition piece — tend to drive down costs.
