China's first affordable offshore wind power project was put into operation at full capacity

Recently, CGN's Shanwei Jiazi-1 500,000-kilowatt offshore wind power project (hereinafter referred to as the "Jiaziyi 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 completion and commissioning of the project is of symbolic significance, providing a "CGN sample" for the development and construction of affordable offshore wind power in China, and has positive significance
for the national ecological environmental protection, energy supply security, the construction of new power systems, the development of clean energy industry, and the realization of the "dual carbon" strategic goal.

Jiazi One Project is located in the sea area south of Hudong Town, Lufeng City, Shanwei City, Guangdong Province, is the first offshore construction in China, the first grid-connected power generation, the first full-capacity grid-connected power generation affordable offshore wind power project, the offshore distance is 25 kilometers, the water depth is 30-35 meters, supporting the construction of one 220 kV offshore rising pressure station, and supporting the construction of CGN Houhu, Jiazi I, Jiazi II and other three projects common 500 kV land rising pressure station, is the highest domestic offshore wind power project
with the highest voltage level 。 The 35 kV submarine cable of the project innovatively uses waterproof insulation bundles to replace the traditional lead sheath process nationwide, and takes the lead in using the applied current basic anti-corrosion technology in the sea area of Guangdong, 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 will officially enter a new stage
of grid parity.
In the face of multiple challenges such as frequent outbreaks of the new crown epidemic in China, complex geology in the East Guangdong Sea, small construction window period, and difficult construction, the CGN project team adhered to the goal orientation, started from the aspects of management improvement, technology optimization, process innovation, etc.
, actively coped with the new situation of parity, scientifically coordinated various work, actively integrated upstream and downstream resources, worked together to jointly tackle key problems, and went all out to promote project construction
.
It took only one year from the start of the project in October 2021 to its completion and operation, creating a new "CGN speed"
.

As a state-owned enterprise with clean energy as its main business, CGN actively responds to the call of the state, adheres to the implementation of the national "dual carbon" strategy, and strives to become the main force in the development and construction of offshore wind power in the country and the vanguard of the national marine development strategy
.
Over the years, CGN has been deeply engaged in the field of offshore wind power, participated in the Shanghai Donghai Bridge Project, the first offshore wind power project in China, independently developed and constructed the first "Double Ten" standard offshore wind power project in China, such as the East Offshore Wind Farm, and built the most difficult offshore wind power project in Pingtan, Fujian Province, providing the industry with technical demonstrations and standard specifications
for engineering construction, operation and maintenance management.

According to reports, up to now, CGN's domestic offshore wind power resource reserves exceed 23 million kilowatts, and 2.
858 million kilowatts of completed projects have been completed, and there are offshore wind power bases in major coastal provinces such as Jiangsu, Zhejiang, Fujian, Guangdong and Shandong
.
At the same time, CGN has focused on building an integrated development model for the whole offshore wind power industry chain, and the three industrial parks of Yangjiang, Shanwei and Huizhou led by Guangdong have achieved good results, and the largest offshore wind farm cluster in the province consisting of Daishan and Shengsi projects has been built in Zhejiang
.

The person in charge of China General Nuclear Power New Energy Holdings Co.
, Ltd.
said: "With the full capacity of CGN's Jiaziyi offshore wind power project, the total installed capacity of new energy in China has officially exceeded 30 million kilowatts, entering a new historical development stage
.
In the future, CGN will give full play to the scale, cost and innovation advantages of the industry alliance, focus on building a development community, and strive to lead the sustainable and healthy development of affordable offshore wind power to better help the national carbon peak and carbon neutrality goal be achieved
