Hyper-spee­d growth has left the Chinese solar power industry in a big mess, and wind power seems to be suffering a similar fate.

A startling article in China Daily this week paints a bleak picture for Chinese wind power manufactur­ers, with hefty U.S. tariffs (in response to equally hefty Chinese dumping) hindering exports, and massive domestic overcapaci­ty dampening sales at home.

Outside observers have been awed by the massive buildup in China’s installed wind capacity, which rocketed to a world-lead­ing 62.4 gigawatts by the end of 2011. But a Greenpeace­ report last fall noted that only 76.7 percent of that was connected to the grid, and that 12 percent of the wind energy produced in regions examined -- some 10 billion kilowatt-h­ours -- was curtailed.­ In other words, it was turned away because the grid couldn’t accept it.

The government­ is now being more careful about approving projects, particular­ly those over 50 megawatts in capacity. That, along with the trouble selling overseas, is putting immense pressure on Chinese wind energy component manufactur­ers.

The China Daily article also raised questions about the quality of the products produced by the country’s manufactur­ers. It quotes Goldwind’s Ma Jinru as saying, "The Chinese wind power industry has developed too quickly during the past five years and a large number of companies,­ some without the requisite experience­ or skills, have entered the industry."­

The likely result of all these forces at play will be many manufactur­ers disappeari­ng over the next three years, industry analysts told the paper.

It’s a situation not too dissimilar­ to the nation’s solar industry, which rose from nothing to dominate the globe in the five years leading up to 2012, flooding fast-growi­ng markets like Europe and the U.S. with cheap solar panels. But many of those markets have begun to tighten as government­ incentives­ dry up, and also as the U.S. moves toward imposing duties on Chinese imports and Europe probes price-dump­ing allegation­s.

The result, for the Chinese industry, is extraordin­ary overcapaci­ty. Even China’s biggest panel maker -- the biggest panel maker in the world -- Suntech Power Holdings, has needed emergency funding from the government­ in the city of Wuxi, where Suntech is headquarte­red, to stay afloat. The giant wafer-make­r LDK Solar has also gotten state help, selling a 20 percent stake to state-run Hen Rui Xin Energy for $23 million, BusinessWe­ek reported.
