China's first affordable offshore wind power project has achieved full-capacity grid-connected power generation

Recently, CGN's Shanwei Jiazi-1 500,000-kilowatt offshore wind power project (hereinafter referred to as the "Jiazi-1 Project") successfully realized the grid-connected power generation of 78 wind turbines, marking the first affordable offshore wind power project in China to achieve full-capacity grid-connected power generation, and also marking the official completion and operation of the first million-kilowatt-level offshore wind power base in eastern Guangdong (including CGN's 500,000 kilowatts in Shanwei Houhu Lake and 500,000 kilowatts in Jiaziyi
).
The project provides a sample for the development and construction of affordable offshore wind power in China, and has positive significance
for promoting national ecological environmental protection, energy supply security, new power system construction and clean energy industry development.

Jiazi One Project is located in the sea area south of Hudong Town, Lufeng City, Shanwei City, Guangdong Province, is the first offshore wind power project in China to start offshore construction, the first grid-connected power generation, and the first full-capacity grid-connected power generation affordable offshore wind power project, with an offshore distance of 25km and a water depth of 30-35m, supporting the construction of a 220kV offshore booster station, and supporting the construction of CGN Houhu, Jiazi I, Jiazi II and other three projects to share the 500kV land rising voltage station, is the highest transmission voltage level offshore wind power project
in China 。 At the same time, the 35kV submarine cable of the project innovatively uses waterproof insulating bundles to replace the traditional lead sheath process nationwide, and takes the lead in using the impressed current basic anti-corrosion technology in the Guangdong Sea, which effectively reduces the carbon emissions of the submarine cable life cycle, solves the problems of difficult construction and high project cost, and provides a technical demonstration
for promoting the green, innovative and affordable development of offshore wind power.
After the project is put into operation, it can provide about 1.
5 billion kilowatt-hours of clean electricity per year, which can reduce the consumption of standard coal by about 460,000 tons and reduce carbon dioxide emissions by about 1.
2 million tons, which is equivalent to about 3,400 hectares
of afforestation.

In 2022, offshore wind power officially entered a new stage of grid parity, and the CGN project team actively responded to the new situation
of parity from the aspects of management improvement, technology optimization and process innovation.
Under the policy background of offshore wind price grid, the project construction faces multiple challenges
such as frequent outbreaks of new crown epidemics in China, complex geology in the East Guangdong Sea, small construction window period, and difficult construction.
CGNPC's project team adheres to the goal-oriented, scientifically coordinates all work, actively integrates upstream and downstream resources, works together to jointly tackle key problems, and goes all out to promote project construction, which took only one year from the start of construction in October 2021 to the completion and commissioning of production, creating a new "CGN speed"
.

CGN has made great efforts to build an integrated development model for the whole offshore wind power industry chain, and has achieved good results in the three industrial parks of Yangjiang, Shanwei and Huizhou led by Guangdong, and built the largest offshore wind farm group
in the province consisting of Daishan and Shengsi projects in Zhejiang.
Zhang Zhiwu, Secretary of the Party Committee, Chairman and General Manager of CGN New Energy Holdings Co.
, Ltd.
, said: "With the full capacity of CGN's Jiaziyi offshore wind power project, CGN's total installed capacity of new energy in China has officially exceeded 30 million kilowatts, entering a new historical development stage
