China's Wind Power Industry: Blowing Past Expectations

Bejing, China [RenewableEnergyWorld.com]

At the end of 2007, China's installed base of wind power totaled just over 6 gigawatts (GW), making China the fifth largest producer of wind power, after Germany, the U.S., Spain and India. As a consequence of the rapid build-out of wind power projects in China, in April 2008 the National Development and Reform Commission revised its 11th Five Year Plan Period plan for wind power development from 5 GW to 10 GW by 2010.

By 2015, installed capacity of wind energy will have reached 10 GW or more and by 2020 Gansu is expected to have 20 GW of wind power in the Jiuquan corridor.

More impressively, wind power industry statistics show that by the end of 2008 China's total installed base of wind power production will have already reached 10 GW, two years ahead of the revised plan. Some experts are estimating that by 2010, the total installed capacity for wind power generation in China will reach 20 GW and that by 2020 China's installed base of wind power will total 100 GW.

Estimates by experts in wind power development in Inner Mongolia have an even more optimistic assessment; they believe that by 2010 China's total installed base of wind farms will total 27,700 megawatts (MW) and that China will then be the fourth largest producer of wind power in the world. The Inner Mongolia experts further predict that China will become the third largest producer of wind power worldwide by 2015.

From Xinjiang in China's far west to Shanghai, wind power projects are being developed across China. Below are highlights of local efforts to build-out wind power capacity throughout China.

Inner Mongolia

Of the 230 million kilowatt-hour (kWh) wind potential throughout China, it is estimated that Inner Mongolia has wind resources of approximately 101 million kWh or 40% of the total. There are some 200 companies that already have entered or plan to enter Inner Mongolia's wind power industry.

Through the end of 2005, total installed on-grid wind generating capacity was 170 MW and there is another 962.1 MW of installed wind generating capacity already under construction. By the end of 2010 Inner Mongolia expects to have a total of more than 5 GW of wind projects operating, which will amount to 7.5% of total power generating capacity in the region.

Yet based on the announced projects, it is likely that the total amount of wind power capacity in Inner Mongolia by the end of 2010 will exceed 5 GW. For example the city of Chifeng already has entered into an agreement with the Datang Company to develop 1 GW of wind power and by the end of 2010 Chifeng city alone is expected to have total installed capacity of 1.5 GW.

Gansu Province

The Hexi (west of the Yellow River) corridor near Jiuquan city, which has been dubbed the "Land-Based Three Gorges," is the locus of development of Gansu Province's substantial wind resources. In this area there is an estimated 10,000 square kilometers of land which can be used for wind power development and the estimated capacity that can be developed there is 40 GW.

Though Gansu Province's long-term wind power development plan calls for the construction of 18 large and mid-sized wind farms with a total installed capacity of 20 GW, through the end of 2007 there were a total of 500 MW of wind farms operating, with another 1 GW in planning. Gansu's plan calls for 3 GW to be added in the last three years of the 11th Five Year Plan period, so that by 2010 there will be 4 GW of wind power in operation in Gansu Province. By 2015, installed capacity of wind energy will have reached 10 GW or more and by 2020 Gansu is expected to have 20 GW of wind power in the Jiuquan corridor.

Shandong Province

The province of Shandong is undergoing a boom in wind power development. There are five wind farms that were under construction in 2007, including one each in Rongcheng, Dongying, Zhanhua, Shougang and Weihai. In total these five wind farms are to cost 2.5 billion Yuan and provide a total of almost 300 MW of power generating capacity. Because Shangdong Province is a coastal province bordering the East China Sea, provincial officials estimate that the province has upwards of 67 GW of wind power resources; this is equivalent to 3 Three Gorges Projects.

Long term, engineers in Shangdong believe that there can be as many as 38 wind farms producing power in Shangdong. According to the provincial government's plan, Shandong will have 1 GW of wind power generating capacity by 2010 and 3 GW by 2020.

Heilongjiang Province and its capital Harbin also are making strides to develop wind power. Surveys indicate that the wind resources in Harbin alone are equivalent to 10 GW of power and that with existing technology the exploitable wind power in Harbin is ~ 1 to 2 GW. The Mulan Wind Power Plant, which was started up in 2004, has installed capacity of 12 MW.

According to a National Development and Reform Commission plan, Shanghai will build a total of 13 land and sea-based wind farms in Nanhui, Qinjian and three islands (Chongming, Changxing and Hengsha). By 2020 Shanghai will have a total of 1 GW of installed wind power generating capacity, which will be sufficient to supply power to 4 million residents. Presently Shanghai has three wind farm projects operating, including the Shanghai New Energy Environmental Protection Engineering Co., Ltd.'s four wind turbines with combined capacity of 34 MW; the Shanghai Wind Power Development Co., Ltd.'s 21 MW wind turbines; and the 13 wind turbines located in Nanhui and Chongming which produce 42 GWh/year combined.

The Ala Mountain Pass region of Xinjiang Province is one of that province's best locations for the development of wind power projects. According to plans developed by the provincial government by the end of the 12th Five Year Plan period (in 2015) this area will have an installed base of wind farms totaling 1 GW.

Construction has been completed on the first stage of the Beijing Guanting Wind Farm project. The thirty-three windmills have a total capacity of 50 MW. Based on average consumption by Beijing residents of 1000 kWh/year, the Beijing Guanting Wind Farm will be able to provide power to approximately 100,000 households. After the second phase of the Beijing Guanting Wind Farm is constructed (by 2010) the project will be generating 100 MW in clean wind power.

Hainan Province has drafted a plan to encourage the development of 13 wind farms to be located primarily in the Eastern, Northwestern and Western coastal areas of the province. The anticipated total capacity of wind power to be developed in Hainan through this plan is more than 1.2 GW; of this total Hainan Province anticipates having between 4 and 6 wind farms operating by 2010 with total installed capacity of 250 to 300 MW at a cost of approximately 3 billion Yuan. By 2015 Hainan Province's installed capacity to produce wind power will have grown to 400 MW and by 2020 will grow again to 600 MW.

The Daan city region is the location of some of Jilin Province's most plentiful wind resources; with an area of some 1200 square kilometers that region has the potential to develop as much as 6 GW of wind power. If the full potential of the Daan city region's wind resources were exploited, as much as 12 billion kWh of power could be generated from wind power in that region, which also has good infrastructure for the transmission of power generated there.

Because wind power is proving to be a cost competitive source of power for this energy thirsty nation, the Chinese are aggressively ramping up capacity wherever wind resources can be found. As Chinese manufacturing prowess is increasingly put at the disposal of the wind power industry and the cost of wind power further declines, the rate of growth of wind power installations will continue to accelerate.

Next month RenewableEnergyWorld.com will look at the growth of indigenous Chinese manufacturing capabilities for wind turbines, blades and other components of the wind power industry.

GLEN BOLTON'S wish has come true through the discovery of "whale power" by Dr. Fisher: He detected that the bumps on the humpback whales fins, called tubercles, increase the whales capabilities to make sharp turns. Wind tunnel tests have revealed that turbine blade edges with these tubercles will put out about 20% more power and create less noise. The first wind generator with this new blade design has been installed as a prototype.

I am a retired aeronautical engineer and have been enthusiastic about the
fact that wind power has finally caught on in a big way. I have thought that
there should be some further research and testing done to find one or more suitable alternate designs for large wind turbines.
With the amount of investment now going into the existing design there should be funds available to make some reasonable attempt to design large units that could take advantage of lower speed winds that exist at the lower levels on existing wind farms. I understand that wind velocity is of primary
importance, but larger slower moving turbines could concievably create a
sufficient amount of torque with the slower winds to produce a practical
amount of power that could be fed into the existing grid of the conventional
wind farm. I am working on a design that I believe might just fill the bill.

Is there anyone out there who is working on alternative large scale designs?
I am familiar with some of the vertical axis concepts, which dont seem to be
capable of competing with the propeller versions, but maybe there is an "out
of the box" design that could work.

I'm sure that all of the cold, hungry mouths in China will will work hard because they require more power and will help their country grow as a world leader in these emerging fields. Just look at what they've accomplished already, and, good for them! Good for all of the world, eventually, as these technologies do tend to spread around.

China has the brute force of the larger number of intelligent people, and we can expect a proportionate number of problem-solvers to population, and using the punchline of an old unfortunate joke making fun of linguistic challenges when speaking English, "Many hands make light work" will likely be a very huge awakening to America and the rest of the world when they've got their lights on, and we in the USA are still arguing about drilling offshore or not.
Oh, and they're holding the note on our lavish homes, too. How'd that happen? Ah... while we were sleeping...

It also seems to me that the Chinese people are still more familiar with a government that expects their participation as part of the solution, rather than one with more individuality and 'not in my backyard' concerns all the time. They seem to work together better, even if at the expense of some of their personal benefit. We seem to be more interested in 'American Idol' than the power source that makes those TV sets work in every room of the house. I'm not encouraging 'more government' (no way, too much already) but I am trying to encourage better cooperation, and a bit of a 'reality check' to those of us who work on the solutions, and getting through all of the bureacracy we already have.

Let's hope that they develop more earth-friendly methods for feeding the power needs of all of those mouths, because we all share the same atmosphere, and I'd rather see more wind power than any of the more-toxic solutions like anything burned.

Yeah, and they're also going to build orders of magnitude more coal fired capacity. Pretty sad situation if you ask me.

It's good to see the optimism and possibilities but setting low goals and blowing past them is not that impressive. China is still rapidly expanding coal power plant at an enormous rate and took over as the #1 CO2 emitter in 2007.

Well, if I remember correctly, China spent last winter in the dark because of power issues. It's in their interest to install as much wind as they can, as fast as possible.

The Chinese dragon is about to breath fire in the world of renewable energy.
They are hot on the mark when it comes to wind, solar and hydrogen and I predict they will become world leaders in these fields.

East and West needs to work together to find a way to solve our energy and pollution problems.

Mr. Stoyke,

Thanks for your reply to my comment. Using whale tubercles on the
wind turbine blades is certaintly, "out of the box" ! More power to them !
Is there any more information about the performance of the prototype?

Someone should try molding tip plates onto the blades to reduce tip losses
due to the tip vortex. Most new jet liners have sprouted winglets at the tips to increase lift and reduce drag. The large diameter propeller turbines
have rather large tip speeds, and efficiency might be improved by a suitable
tip plate extending both above and below the blade. Also, this should allow
a broader blade chord to be used in the high speed working area of the
prop. Maybe it would be too complex. Just a thought. GB

China is developing very fast. That is correct.

I need to say one thing about Co2.
China is actually working very hard to decrease emissions, and if I remember correct, then CO2/citizen is higher in US, and I am afrais that India will be the worst very soon.

About windmill energy in China

My oppinion is, that China should go for big ocean based windmills, instead of land based windmills. The impact on the environment is much lower at ocean based mills, and even that the cost is higher, the efficency is much better, as bigger windmills can be used.

This oppinion is not only regarding China. US and the rest of the world should also go for the Ocean based windmills.

Why is the cost so high for those mills ?
One of the reasons is, that the Ocean Foundation is very expensive.
That cost can be reduced very much, by using the correct suppliers.
F.ex. our company.
We specialize in lowering production cost for steel parts.

But .. it is up to the contractors to establish that.
They stil think, that quality and delivery is not stable in China.
For some parts it is correct, but if the ability to follow strictly up on an order, by being there, the story is different. China as manufactorer is abolutely ok, but it requires that a trusted person follows up on the production.

Glen Bolton,

American Superconductor and Westinghouse in conjunction with the U.S. Department of Energy are trying to engineer and design jumbo 10 megawatt turbines using superconductor technology that would make the wind turbines 66% lighter then current methods. the venture was announced october 2007.

I've read about Tubercles Technology as well. It's actually a lot better than +20%, because the technology works disproportionally better under low speed wind conditions. And those are the most common. I think +100% output in low wind speed areas will be possible, making previously expensive low wind regions very economical.
