China commissions offshore wind power, giving it largest installed base
China is moving fast in its efforts to expand power generation from offshore wind farms. Just last week, the country announced the commissioning of three new projects, including China’s largest offshore wind farm with the largest turbines, the first typhoon-resistant floating offshore wind farm and the expansion of projects in eastern China.
China’s National Statistics Administration recently announced that the country has reached 11.2 GW of installed offshore wind power capacity. This would represent an increase of 7.9 GW at the end of the first half of 2021 and give China the largest operational base of offshore wind farms. The UK was the world leader at the end of 2020 with 10.2 GW of production capacity from offshore wind farms.
The new wind farms are helping China overcome some of the challenges that limit the development of offshore wind farms. The new farms include floating technology and turbines capable of withstanding the high winds and waves associated with a typhoon.
“At present, wind farms are mainly located in the northwestern part of China, while the eastern provinces have the highest consumption of electricity,” China Institute for Policy Studies explained. energy which is part of Xiamen University. The development of offshore wind farms is seen as a critical step for the eastern regions which have limited land resources to establish wind farms.
Construction has been completed on a 300 MW offshore wind farm in the South China Sea. It is the deepest offshore wind farm in China, located in an area of ââharsh sea conditions with complex topography and geological conditions. The builders had to cope with typhoons, thunderstorms and swells. The region’s first turbines were connected to the electricity grid in January and produced 180 million kWh of electricity. When fully operational, the project near Nanpeng Island in Guangdong Province is expected to produce 800 million kilowatt-hours of electricity per year.
The offshore floating wind turbine installed in Guangdong and developed in China is designed to withstand a grade 17 typhoon, which would be a super storm every 50 years. The turbine has a capacity of 5.5 MW.
China’s largest offshore wind farm in terms of unit capacity was also connected to the power grid on December 25. In Jiangsu Province, near the city of Qidong, in eastern China, the park has seven different models of wind turbines for a total of 134 wind turbines installed. . The first turbine was erected in February and the last completed in early December. It is part of a global project located approximately 18 to 25 miles off the Yellow Sea that will have a total capacity of 802 MW.
The first phase of the Guodian Xiangshan 1 offshore wind farm project in Zhejiang province (east China) became fully operational on December 23. It has 41 6.2 megawatt wind turbines connected to a 220 kilovolt offshore booster station. This is the second offshore wind power project developed by GD Power Development Co., giving the company a total of 506,200 kilowatts of installed offshore wind capacity commissioned in the province. The Xiangshan 1 wind project, the first offshore wind project in Ningbo, started on December 25, 2020.
Wind projects are part of the country’s efforts to reduce its dependence on coal-fired power plants. China’s target is for carbon dioxide emissions to peak by 2030. The country has said it will be carbon neutral by 2060.
