On the banks of the South China Sea in Yangjiang, the sea breeze is strong. On March 1, 2026, this sea area, known as the "capital of wind power in China," once again ushered in a shining moment. With the official announcement of the bidding results for the PC general contracting project of Huaneng Yangjiang Sanshan Island's first and second offshore wind farms, a far-reaching offshore wind power construction project with a total investment of over 11.1 billion yuan has officially begun. China Railway Construction Port and Shipping Bureau and China Communications First Navigation Bureau, two major state-owned enterprises, have joined forces to win this super project with a total price of about 4.44 billion yuan, marking a new era of large-scale development of offshore wind power in China.

This bidding is divided into two sections, both of which are 500MW offshore wind farms, with fierce competition and full potential. The first section (Sanshan Island 1) was awarded to China Railway Construction Port and Shipping Bureau Group Co., Ltd. with a bid of 2.23 billion yuan; The second section (Sanshan Island 2) was awarded to China Communications First Navigation Engineering Co., Ltd. with a bid of 2.21 billion yuan. Two major state-owned enterprises have successfully broken through with their advantages in technology, equipment, and construction experience, and will jointly undertake the large-scale wind power demonstration project in the South China Sea.

The Huaneng Yangjiang Sanshan Island 1 and 2 wind farms are located in the deep sea south of Hailing Island in Yangjiang City. It is currently one of the most complex and technically standardized offshore wind power projects in China. The site center is about 90-92 kilometers offshore and is a typical deep-sea offshore wind power project in China. The single site covers an area of 53 square kilometers and has a water depth of 51-57 meters. The construction difficulty is high and the technical requirements are high. The planned capacity of a single project is 500MW, and the total capacity of two projects is 1000MW (1 million kilowatts).

The project adopts 16-17MW ultra large single capacity wind turbines, covering the mainstream large capacity unit range of 14-17MW, representing the highest level in China.

The innovative configuration of one 17MW floating wind turbine in the Sanshan Island project is a rare cutting-edge technology application in China. The project adopts an 8-circuit 66kV collection submarine cable for power transmission, and shares a 2000MW offshore flexible direct current transmission project with the Sanshan Island 3 and 4 projects. It is invested and constructed by Guangdong Power Grid and is the first integrated flexible direct current transmission supporting project between land and sea in China. The transmission efficiency and stability are leading in the country.

This project is not just a simple power generation project, but also a key support for the national dual carbon strategy and the Western Land Sea New Corridor. The annual power generation can provide long-term use for cities with a population of millions, significantly reducing fossil energy consumption. The project will drive the outbreak of the entire industry chain of Yangjiang wind power equipment manufacturing, port logistics, and marine engineering, improve Guangdong's clean energy system, and provide stable green electricity for the Guangdong Hong Kong Macao Greater Bay Area. The breakthrough in deep-sea construction and floating technology provides a model for the development of offshore wind power in the deep sea across the country.

In recent years, the total scale of Yangjiang offshore wind power cluster has exceeded 7 million kilowatts, becoming one of the largest offshore wind power clusters in the world. With the landing of the 4.4 billion PC section, as well as previous survey and design, wind turbine procurement, and flexible transmission sections, the total investment in the Sanshan Island area has exceeded 20 billion yuan, forming a full chain ecology of "wind turbine manufacturing offshore equipment construction grid connected power transmission". As the project accelerates, it is expected to achieve full capacity grid connection by the end of 2026 to 2027. At that time, Yangjiang will add another million kilowatt level green energy aircraft carrier, injecting a continuous stream of "blue power" into Guangdong's high-quality development.Editor/Yang Meiling
