The Chinese government has approved a plan by the Chinese oil and gas company CNOOC to build a 1.5 GW offshore wind park in the South China Sea, west of Dongfang city in the Hainan Province (southern China). Once completed, the project is expected to be able to produce about 5 TWh/year of electricity.
The project will be built in two phases. The first phase, CZ7-1 (603.5 MW), will be located 29 km from shore on a 60 km2 area and will be comprised of 71 turbines of 8.5 MW each. The second phase, CZ7-2 (900 MW), will involve the installation of 106 turbines, 38 km from shore on a 126 km2 area. Each phase of the project is equipped with a 220 kV offshore rising station and an onshore centralized control center.
China’s offshore wind capacity stood at 26.4 GW at the end of 2021 and reached an estimated 30.5 GW at the end of 2022. This is the world's largest operational offshore wind capacity, even if it represents only about 1% of China’s total installed capacity. Around 17.4 GW of offshore wind projects were commissioned in 2021 alone and 4 GW in 2022 (according to preliminary estimates). The country’s overall wind capacity reached 328 GW at the end of 2021 (366 GW in late 2022). China has nearly 26 GW of wind under construction and more than 36 GW under development.
