Before producing electricity, a giant wind turbine must find space somewhere. On an enormous dock, inside a port capable of handling blades as long as buildings laid flat, massive nacelles, towers to be assembled with special cranes, and weather windows good enough to allow operations. The wind remains the simple part to describe. The rest is steel, logistics, seabeds, submarine cables, maintenance, and an amount of money that makes every mistake far from romantic.
Offshore wind power, installed at sea, has entered its biggest season. In China, the most recent machines have exceeded a scale that until a few years ago seemed almost like a rendering: rotors wider than 984 feet (300 meters), blades over 492 feet (150 meters), and a single turbine capable, under the right conditions, of producing electricity for tens of thousands of families. Today’s record machine is Dongfang Electric’s 26 MW offshore turbine, installed at the end of August 2025 at the Dongying test and certification base in Shandong, and connected to the grid at the end of October. It has a rotor of approximately 1,017 feet (310 meters), blades of 502 feet (153 meters), and a swept area of about 828,821 square feet (77,000 square meters), more than ten soccer fields combined.
Right behind Dongfang’s 26 MW is a new range between 20 and 25 MW, almost entirely Chinese. Shanghai Electric has presented the EW25.0-310, an offshore turbine of 25 MW with a 1,017-foot (310-meter) rotor. On paper it’s in the same class as Dongfang’s, although it remains a prototype promise rather than a machine already proven in commercial wind farms.
More concrete is the case of the 20 MW turbine installed by Goldwind and China Three Gorges off southern Fujian in January 2026: more than 19 miles (30 kilometers) from the coast, over 131 feet (40 meters) deep, with a 984-foot (300-meter) rotor and 482-foot (147-meter) blades. Here the 20 MW threshold has truly gone to sea.
Europe proceeds with a less spectacular and more industrial pace. The Vestas V236-15.0 MW has a 774-foot (236-meter) rotor and blades of about 377 feet (115 meters), and is already chosen for major offshore projects. In the United States, Vineyard Wind 1 uses 62 GE Vernova Haliade-X 13 MW turbines, with a 722-foot (220-meter) rotor and 351-foot (107-meter) blades. Smaller dimensions compared to Chinese giants, certainly, but still enormous by any human measure.
