A 26-megawatt offshore wind turbine that has been commissioned for grid-connected power generation in Dongying, east China's Shandong Province, is the world's largest of its kind by far, according to its developer.

Independently developed by Dongfang Electric Wind Power Co Ltd and fully domestically produced, the wind turbine is the world's largest in terms of the single-unit capacity and the rotor diameter exceeding 310 metres, said Yang Senlin, vice president of the company's wind power research and design institute.
