China Huadian has begun full‑scale construction of a 500 MW offshore wind farm on Sanshan Island, south of Hailing Island in Yangjiang, Guangdong Province, after installing the first turbine at what is currently China’s farthest‑from‑shore project. The state‑owned power generator described the project as a milestone in the country’s offshore wind push and the Greater Bay Area’s energy transition.
The wind farm covers 54 square kilometres of sea area, with water depths ranging from 46 to 50 metres. Its centre lies 82 kilometres from the nearest land, with the farthest turbines as much as 89 kilometres offshore. The project will deploy 31 turbines, each rated at 16.2 MW, marking China’s first large‑scale application of this model.
China Huadian said the project will use big data and intelligent algorithms to monitor turbine conditions, diagnose faults and optimise operations, targeting a 1-2% increase in output, a 20% reduction in fault rates and 5-10% higher returns.
When fully operational, the farm is expected to generate about 1.6 billion kilowatt hours of clean electricity annually, and cut standard coal consumption by more than 500,000 tonnes and CO2 emissions by 1.26 million tonnes each year, according to Li Xiang, project director for the Sanshan Island wind farm.
