85.5 kilometers! China builds the farthest offshore wind farm connected to the grid--Seetao

On December 15, 2025, when the last giant wind turbine blade began to rotate deep in the Yellow Sea, China's offshore wind power entered a broader "deep blue". On this day, the Three Gorges Jiangsu Dafeng 800 MW offshore wind power project achieved full capacity grid connection. It is located 85.5 kilometers offshore, making it the farthest offshore grid connected project in China to date, marking the successful entry of China's offshore wind power into the deep sea. The farthest offshore distance of this project is 85.5 kilometers, far exceeding conventional offshore wind power projects. This distance poses unprecedented challenges to the reliability of wind turbines, the stability of power transmission, and offshore construction and operation. The successful grid connection of the project means that China has systematically mastered and broken through a series of key technological bottlenecks in the development of offshore wind power. A total of 98 wind turbines were installed in the project, with a total installed capacity of 800 megawatts. Three offshore booster stations and one offshore rescue platform were also constructed as supporting facilities. After being fully put into operation, it can annually deliver a large amount of clean electricity to the power grid, significantly optimizing the regional energy structure and providing stable impetus for the green development of the Yangtze River Delta region. The completion of the Dafeng project is not only the completion of a power station, but also a concentrated demonstration of China's wind power industry capabilities. It has accumulated valuable experience and verified the technological system for the future large-scale development of deep-sea wind power resources in China, and is a solid milestone for the industry to march towards deeper and broader oceans.
