Dongying of East China's Shandong province finished the world's largest 26-megawatt-class offshore wind turbine on Aug 29. It was fully developed using China's own independent intellectual property and provides strong technological support for China's advancement in ocean-related industries.

The turbine consists of over 30,000 components, with a fully independent and controlled supply chain. Core parts — including the generator, blades, bearings, and control systems — meet world-leading standards.

The blades measure 153 meters in length and weigh 76 metric tons, with a hub height equivalent to a 50-story building. The rotor's swept area covers 77,000 square meters, roughly equal to 10.5 standard football fields, making it the world's largest offshore wind turbine in terms of unit capacity and rotor diameter.

Under rated conditions, each rotation of the turbine generates 62 kilowatt-hours of electricity. A single unit can produce 100 million kWh of clean energy annually — equivalent to a small conventional wind farm and enough to power 55,000 households for a year. It can save over 30,000 tons of standard coal and reduce CO? emissions by more than 80,000 tons. The turbine enhances generation efficiency and supports the development of cost-competitive offshore wind power.

The completion of this turbine marks a milestone in offshore wind power development and showcases Dongying's growing role in advancing clean energy technologies. It not only strengthens China's renewable energy capacity but also contributes to global efforts in achieving a greener, low-carbon future.
