6 FAQs about [Wind turbine blade length power generation capacity]

How much power does a wind turbine produce?

The trend towards large blades. Our formula above also showed that the potential power generation of a wind turbine is a square function of its blade length. Doubling the blade length from 50 meters to 100 meters might thus increase the potential power output by a factor of four (2^2=4), from around 3MW to 12MW.

How long is a wind turbine blade?

This equates to a blade length of somewhere around 60 meters. This is considerably less than the 107 meter long blades on the Haliade-X 12 MW offshore wind turbine. Some lower capacity onshore wind turbines feature longer blades than the Enercon E-126 7.580 MW.

Why is wind turbine blade size important?

Wind turbine blade size plays a big role in the amount of energy a turbine can produce. Simply put, larger blades equal more power, which is why there’s been a consistent trend toward bigger turbines in the wind energy industry.

How is the power of a wind turbine calculated?

Specifically, how is the power of a wind turbine calculated, in MW, as a function of wind speed, blade length, blade number, rotational speed (in RPM) and other efficiency factors (lambda). A large, modern offshore wind turbine will have 100m blades and surpass 10MW power outputs.

Why do turbines have longer blades?

Turbines with longer blades cover a larger area, allowing them to collect more wind and generate more power. The relationship between blade size and energy is exponential, meaning that doubling the blade length increases the power capacity by a factor of four.

What are wind turbine blades made of?

Forty years ago, wind turbine blades were only 26 feet long and made of fiberglass and resin . Today, blades can be 351 feet, longer than the height of the Statue of Liberty, and produce 15,000 kW of power. Modern blades are made from carbon-fiber and can withstand more stress due to higher strength properties.
