The China Three Gorges Corporation (CTG), a state-owned power company, completed many a major milestone last month in its efforts to boost the country's offshore wind industry.
Phase II of the Shapa offshore wind power project in Yangjiang, built by CTG, went into full operation on November 27, delivering green and clean electricity to power the Guangdong-Hong Kong-Macao Greater Bay Area, revealed a recent announcement.
Located in the western sea of Shapa, the project has 62 units of 6.45-MW offshore wind turbines, with a total installed capacity of 400,000 kilowatts. It is expected to generate about 1.088 billion kWh annually, reducing carbon dioxide emissions by about 442,600 tons and saving about 346,000 tons of standard coal.
CTG also announced that the H6 (400,000 kW) offshore wind power project in Rudong, Jiangsu Province, funded and built by its alternative energy arm China Three Gorges Renewables (Group) Co., went into operation on November 29. The company considers it another major achievement in constructing a GW-level offshore wind power base in Jiangsu region.
The Rudong project is also of great significance for the exploration of large-capacity, long-distance offshore wind power technology, added CTG. The project plans to build two offshore wind farms, H6 and H10, each with 100 4-MW wind turbines.
The generated electricity will be transmitted through the flexible DC transmission cable featuring higher voltage class and longer transmission distance than any other counterpart in China. "Flexible DC transmission, the most cutting-edge power transmission technology in the world, can address the deficiencies found in traditional long-distance AC power transmission," says CTG.
Additionally, CTG-owned Dafeng offshore wind power project completed the installation of all its wind turbines in Jiangsu on November 28. Located in the northern sea of Maozhusha, Dafeng District, the furthest offshore wind power project in China is 72 kilometers away from the shore. It comes with 38 4.5-MW wind turbines and 20 6.45-MW wind turbines.
The project marks the first domestic application of offshore high-resistance stations in addressing the issues of long-distance power transmission. The offshore wind power project also features the highest voltage class among domestic shore-based centralized control centers, said CTG.
