How much does a generator blade cost

Blades make up approximately 20% of the total cost of the turbine. The cost varies based on the materials used. Blades are manufactured either with glass fiber or a hybrid of glass and carbon fiber. While glass fiber blades have lower material costs, hybrid blades require less labor.

Overall Blade Cost. The total blade cost is estimated at $154,090.40, with variable costs representing more than 70% of the total costs. Table 26 and Figure 4 show the detailed breakout of the total costs of the blade of the IEA land-based reference wind turbine. Table 26.

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.

For short-haul wind turbine shipments, average charges are roughly $30,000 to $40,000 per turbine. At a much higher price point, long-haul wind shipments can cost more than $100,000.

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. Thirdly, the gearbox is estimated to account for 13% of the total turbine cost.

6 FAQs about [How much does a generator blade cost ]

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 rotor blade cost?

The wind turbine blade in this study has a rotor diameter of 130 meters and a mass of 14,285 kg. Its bill of materials totals to $73,638.82. The machine, which has been developed by the Technische Universität München and NREL, mounts this blade on a tower reaching 110 meters at hub height.

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.

How much does a wind turbine cost?

Even more so when you factor in taxes, government incentives, and tariffs. Large wind turbines built for onshore and offshore wind farms can generate about 2 to 3 MW, while the largest offshore turbines can generate up to 12 MW of electricity. Needless to say, they’re expensive. While costs can vary, they generally hover around $1 million per MW.

How are wind turbine blades delivered?

With wind turbines, it must be delivered to the wind farm site from the port of entry or the manufacturer. Some parts even need to be disassembled for shipping. However, the blades must be delivered in one piece. On average wind turbine blades’ size are 116 feet in length. They are still manageable for truck transportation at this length.

How long should a wind turbine blade be?

Wind turbine blades have gotten longer over time. Today, a length of 170 ft. or longer is typical for a utility scale wind turbine blade, while a residential wind turbine blade may be only 25-50 ft. long. A major reason for the increasing length is their greater energy capacity as the diagram below illustrates.
