The world’s largest offshore solar farm is in operation

Located off the coast of Khanli District, Dongying City, Shandong Province, Eastern China, the project spreads over an area of ​​more than 1,200 hectares, including 2,934 solar power platforms, each 60 m long and 35 m wide, equivalent to 5 standard basketball courts.

The project was developed by Guohua Energy Investment Company, a subsidiary of China Energy Investment Group (CHN Energ), and applied many technological innovations. For the first time in China, the solar power sector uses a combination of 66 kV offshore cables with onshore cables to transmit high-capacity electricity over long distances, helping to increase transmission capacity while reducing costs. The project is expected to become a model for the development of large-scale offshore solar farms.

The project uses fixed pile foundation techniques with large-scale steel truss frames in an innovative way. Zhang Bo, deputy project manager of Khanh Li at Guohua Energy Investment Company, said the “four-pile foundation combined with solar platform” structure with precisely adjusted 15-degree inclined panels helps withstand strong winds of level 11 and winter ice conditions, while reducing the amount of steel used by more than 10%, providing valuable experience for the construction of future offshore solar farms.

When fully operational, the farm is expected to produce 1.78 billion kWh of electricity per year, enough to meet 60% of Khan Loi district’s electricity needs. According to CHN Energy, the farm will help save 503,800 tons of standard coal, reducing emissions of 1.3447 million tons of CO2.
