The residential and commercial reference distributed wind system LCOE are estimated at $240/MWh and $174/MWh, respectively. Single-variable sensitivity analysis for the representative systems is presented in the 2019 Cost of Wind Energy Review (Stehly, Beiter, and Duffy 2020).
The answer ranges from hundreds of thousands to several million dollars per blade, depending on size, materials, and application. But the real cost story doesn't end there.
On average, therefore, wind turbines do not generate near their capacity. Industry estimates project an annual output of 30-40%, but real-world experience shows that annual outputs of 15-30% of capacity are more typical. With a 25% capacity factor, a 2-MW turbine would produce in.
According to The United States Department of Energy, most modern land-based wind turbines have blades of over 170 feet (52 meters). This means that their total rotor diameter is longer than a football field.
Typical cost range for a single wind turbine blade spans from roughly $80,000 to $350,000, depending on blade length, composite materials, and engineering requirements.
