On the vast South China Sea and the azure waters, white wind turbines are rising from the ground. The CGN Yangjiang Fanshi offshore wind power project will achieve full capacity operation on September 24, 2026, marking the birth of the first large-scale new energy project in China to use 18 MW ultra large offshore wind turbines, injecting strong momentum into the green transformation of the Guangdong Hong Kong Macao Greater Bay Area.

Batch landing of 18 MW wind turbines

The project is located in the southern sea area of Nanpeng Island, Yangdong District, Yangjiang City. It consists of two million kilowatt level sub projects, Fanshi 1 and Fanshi 2. The farthest point of the site is 81 kilometers away from the shore, and the maximum water depth is 53 meters. The project is equipped with 131 wind turbines, of which 33 are 18 MW ultra large offshore wind turbines, making them the largest single machine capacity in China. The diameter of the impeller of this type of fan is 292 meters, with a sweeping area of about 66000 square meters. Under full load, the impeller rotates once to generate electricity of about 43 degrees, and the annual power generation of a single unit reaches 56 million kilowatt hours. Batch application effectively reduces the layout of machine positions, saves costs on cable laying, foundation construction, and sea area occupation, and promotes the continuous reduction of electricity costs.

Cracking the Difficulty of Deep Water Grid Connection

The offshore lifting of ultra large components in deep water environments is a recognized challenge in the industry. The offshore booster station in Fanshi weighs 6168 tons, and the total weight of the 18 MW wind turbine hoisting exceeds 1500 tons. The project seized the opportunity for offshore operations and successfully completed the transportation and hoisting of large components at sea, forming a scalable complete set of construction plans for deepwater ultra large equipment. The project has also built the first 500 kV intermediate reactive power compensation station for offshore wind farms in China, solving the grid connection problems such as offshore distance, long transmission, and high voltage loss. After full capacity operation, the project will annually deliver over 6.6 billion kilowatt hours of clean electricity, save about 1.92 million tons of standard coal, reduce carbon dioxide emissions by about 5.1 million tons, and help Yangjiang become the largest prefecture level city in China for offshore wind power installation.Editor/Min Jing
