Speaking at an annual meeting of the National People's Congress, vice-minister of China's Ministry of Industry and Information Technology Miao Wei said he was concerned about the lifespan of turbines in sandy areas and how the electricity could be supplied.
Miao is particularly concerned about the huge wind project in Jiuquan City, in China's northwestern Gansu province and the country's first 10GW development.
He compares the project to the Three Gorges hydro-electric project in Hubei province. Most of the electricity it generates goes to the east of the country rather than Hubei itself.
The view is quietly shared by a number of people within the industry who suggest China's grid is not up to scratch in terms of distributing electricity produced by wind.
However, Miao's comments were lambasted by Sinovel chairman Han Junliang who said the minister was defeatist and the view that turbines could not withstand sandy conditions was misinformed.
