China Huadian Yangjiang Offshore Wind Farm Starts Full Construction: A Milestone in Far-Shore Wind Power

Recently, China Huadian’s Yangjiang Sanshandao Liu Offshore Wind Farm Project successfully completed the hoisting of its first wind turbine and officially entered full-scale construction. As the farthest offshore wind power project under construction in China to date, it is also the country’s first project to apply 16.2-megawatt offshore wind turbines on a large scale.

Located in the sea area south of Hailing Island, Yangjiang City, Guangdong Province, the project boasts a total installed capacity of 500,000 kilowatts, covering a wind farm area of 54 square kilometers with water depths ranging from 46 meters to 50 meters. The center of the site is 82 kilometers away from the land, and the farthest point is 89 kilometers offshore, posing high requirements for construction technology and operation management.

The project is designed to install 31 wind turbines with a single unit capacity of 16.2 megawatts. Leveraging big data and intelligent algorithms, it will realize intelligent perception of wind turbine status, intelligent fault judgment and intelligent coordination of operation and maintenance. This intelligent management model is expected to increase power generation by 1% to 2%, reduce the comprehensive failure rate by 20%, and improve the wind farm’s revenue by 5% to 10%.

To address the complex operating environment in the far-shore sea area, the project will adopt a number of advanced technologies and equipment, including China’s first steel-concrete sandwich tower, 500-kilovolt submarine cable cross-section optimization and mass application of aluminum-core submarine cables. These measures will help overcome a series of construction and technical difficulties, providing technical and management demonstrations for the construction of similar projects in the future.

CCTV News reported that upon completion, the project will be able to supply approximately 1.6 billion kilowatt-hours of clean electricity annually, meeting the annual living electricity needs of about 700,000 households. This is equivalent to saving more than 500,000 tons of standard coal and reducing carbon dioxide emissions by 1.26 million tons, which will effectively help optimize the energy structure of the Guangdong-Hong Kong-Macao Greater Bay Area.

Li Xiang, person in charge of Huadian Yangjiang Sanshandao Liu Offshore Wind Farm, noted that the project is a key practice in China’s offshore wind power development towards far-shore and large-capacity directions. Xinhua News Agency stated that China’s offshore wind power industry has maintained a leading position globally, with continuous breakthroughs in domestic substitution technologies and large-capacity wind turbine applications.
