Adhering to the mission of clean energy development, the Three Gorges Group has moved from the Three Gorges to the Yangtze River and from the Yangtze River to the ocean. The Three Gorges Yangjiang Shapa Offshore Wind Power Project is located in the sea area south of Shapa Town, Yangjiang City, Guangdong Province. It is planned for five phases with a total installed capacity of 1.7 million kilowatts. A total of 269 offshore wind turbines are deployed. The 220kV submarine cable is connected to the land-based centralized control center. This project is the first "million kilowatt-level" offshore wind power base in China, and is a pioneer in the development of China's offshore wind power on a large scale.

Geological conditions are the difficulty of offshore wind power development. The project innovatively used a variety of construction techniques and foundation forms, among which multiple foundation forms such as suction tube jacket, single-column composite tube, core-column rock-socketed jacket, and large-diameter four-pile jacket were used for the first time in China and completed. At present, the jacket foundation of the inclined pile-socketed rock-socketed sea rising pressure station is the only one in the domestic offshore wind power industry. At the same time, the project has set a record of domestic offshore wind power construction speed many times during the construction process.

It is estimated that after the completion of the Yangjiang Offshore Wind Power Project, it will provide 4.7 billion kilowatt-hours of on-grid electricity, which can meet the annual electricity consumption of about 2 million modern households. Compared with coal-fired power plants of the same scale, it can save about standard coal every year. 1.5 million tons of carbon dioxide emission reduction of about 4 million tons will provide strong support for the transformation of the energy structure of the Guangdong-Hong Kong-Macao Greater Bay Area.

Three Gorges Energy will continue to conquer key technologies and practice demonstration and leadership. In the process of building a new power system with new energy as the mainstay, Three Gorges Energy, a subsidiary of the Three Gorges Group, will actively promote the development of new energy business by focusing on "wind and wind synergy, sea and land development". The goal of "carbon peak and carbon neutral" has been achieved. Editor/Sang Xiaomei
