4 FAQs about Weight of wind turbine

How much does a wind turbine weigh?

Modern wind turbines are absolute monsters, weighing between 200-400 tons each – that's like a small fleet of commercial airplanes stacked on top of each other. The tower alone accounts for up to 40% of the total weight, while the massive blades tip the scales at 5-15 tons each. The foundation? A whopping 1,000 tons of concrete.

How big is a wind turbine blade?

Wind turbine blades used in commercial, utility-scale turbines are typically very large, with lengths reaching up to 150 feet (46 meters) or more. The larger the blade, the more energy it can capture, but this comes at the cost of increased weight. Blade Length: The length of the blade directly impacts its weight.

How much does a GE wind turbine weigh?

That's right – each one weighs about as much as a small fleet of commercial airplanes. The GE 1.5-megawatt model, a relatively modest specimen, weighs in at 164 tons, while the beefier Gamesa G87 2-megawatt turbine hits a whopping 334 tons. Let's break it down piece by piece, because these monsters aren't exactly built like your backyard windmill.

What is a 'normalised mass' of a wind turbine?

Table 3.3: Blade Mass of Very Large Wind Turbines Note: The 'normalised mass' is an approximate adjustment to bring all the designs to a common point of reference relative to any one design (in this case REpower 5M), taking account of different diameters and different relations between rated power and diameter.
