where are the blades for a generator in a wind farm made?
Because wind turbine blades are massive—some reaching over 100 meters (330 feet) in length—they are rarely shipped across oceans. Instead, they are manufactured in specialized regional hubs located near major wind farm developments or deep-water ports.
As of 2026, wind turbine blade manufacturing is concentrated in several key global regions:
1. The Global Leaders
China: By far the world's largest producer. Companies like Goldwind, Envision, and Mingyang operate massive factories, particularly in provinces like Fujian and Guangdong.
China currently holds over 50% of the global market share for blade production. Europe: A pioneer in wind tech, with major hubs in Denmark (Vestas), Germany (Nordex/Siemens Gamesa), and Spain.
United Kingdom: The Siemens Gamesa factory in Hull is a major global player, recently unveiling world-first recyclable blades for offshore wind farms like Sofia and Dogger Bank.
United States: Focuses heavily on domestic supply. Vestas has a massive manufacturing footprint in Colorado (Windsor and Brighton), while GE Vernova operates facilities across the country to serve the North American market.
2. Emerging & Specialized Hubs
India: A growing hub for both domestic use and export, with companies like Suzlon and Winergy based in Pune and Aurangabad.
Brazil: Recently became a significant player in South America, with GE and Goldwind establishing local manufacturing to bypass high import taxes.
Poland: A new frontier for offshore wind, with Vestas opening a flagship blade factory in Szczecin (scheduled for 2026) to support Baltic Sea projects.
3. Why are they made there?
The location of a blade factory is determined by three "Logistical Laws":
Coastal Access: For offshore wind, blades are so large they cannot be moved by road. Factories must be built directly on "Green Ports" where blades can be slid straight onto specialized installation vessels.
Material Supply: Factories need to be near suppliers of carbon fiber, fiberglass, and balsa wood (used for the blade's core).
Local Content Requirements: Many governments require wind farm developers to use locally-made components to create jobs, which forces manufacturers to build plants in the country where the wind farm is located.
How they are made
Blades aren't "machined" like car parts; they are "baked." Layers of fiberglass and carbon fiber are laid by hand into a giant mold, vacuum-sealed with resin, and cured in a large oven.
Note: While the blades are made in these specialized factories, the generator (the part that actually makes electricity) is housed in the "nacelle"—the box at the top of the tower—which is often manufactured in separate facilities entirely.
Where are the generators manufactured?
Because Dorset is a highly protected landscape (Jurassic Coast, AONB), there are very few large-scale wind farms actually in the county.
1. Alaska Wind Farm (Masters Quarry, near Wareham)
This is the most significant wind farm in Dorset, which became fully operational in early 2024.
The Blades: These were sourced from Belgium.
The Story: Interestingly, these are refurbished Vestas V80 turbines.
To make the project economically viable after a 20-year planning battle, the developer used high-quality "second-hand" turbines that were decommissioned from a site in Europe, refurbished to "as-new" condition, and shipped to Dorset. Manufacturer: Originally manufactured by Vestas (likely in their Danish or German plants before being refurbished).
2. Navitus Bay (The "Almost" Farm)
This was a massive offshore wind farm proposed off the Dorset and Isle of Wight coast that was famously refused planning permission in 2015.
The Factory: Had it been built, the blades would have been made at the MHI Vestas factory in Newport, Isle of Wight.
Impact: This factory is just across the water from Dorset and remains one of the most advanced blade manufacturing sites in the world. Even though the Dorset project didn't happen, that factory currently produces the 100m+ V236 blades for other major UK offshore projects like Dogger Bank.
Other Local "Micro" Turbines
For the smaller, single turbines you might see on Dorset farms (like Rogershill Farm in Bere Regis):
Manufacturer: These are often Vestas V39 or EWT models.
Origin: Most mid-sized turbine blades in the UK are imported from Denmark or The Netherlands, as the UK's domestic manufacturing (like the Siemens Gamesa plant in Hull) focuses almost exclusively on the "giant" blades for offshore use.
