Wind Turbines Manufacturer in China

“China’s wind market nearly doubled every year from 2006 to 2010, and domestic small wind  turbine makers kept expanding capacity when growth stalled in 2011,” Charles Yonts, an analyst at CLSA in Hong Kong, said. “They will be working off the excesses for a couple years and pushing exports, especially to emerging markets.”

China Development Bank, which offered a $6 billion credit facility to Goldwind in 2010 for international expansion, loaned about 93.8 billion yuan to clean energy and a group of energy- saving projects that year, according to London-based New Energy Finance.

Goldwind and domestic wind turbines rivals are seeking orders overseas to overcome slowing sales growth in the second-largest economy after the government tightened criteria for approving new projects. Goldwind bought two 10-megawatt wind farms in Montana this month and has orders in seven other US states. Sinovel said it expects 2011 earnings to fall by more than 50 per cent as competition at home and abroad dragged down prices.

Renewable energy is one of seven strategic industries receiving government support as the China attempts to diversify away from coal, which fuels 70 per cent of the economy.

The focus is now on increasing operating effi- ciency, resolving performance issues rapidly, having real-time control and visibility, and reduc- ing the maintenance time. Providing a compelling service solution is nearly as important as supplying best-in-class equipment, she says.

Quality after-sales services can easily add a few percentage points in efficiency gains, which result in a lower levelised cost of electricity. The Chinese manufacturers can undoubtedly deliver a cheaper wind turbine, which means lower capital expenditure; however, when an entire package is considered, they are still behind their Western counterparts.

“Even if a compelling service offering is developed in their domestic market, unfolding a large-scale after-service support in overseas markets will require a large initial investment. While Chinese wind turbine manufacturers are generously sponsored by the government, there are other priorities for them to address. It is unlikely they will be channelling significant funds into expanding their service offering in those markets, where they do not even sell much.

“Thus, established wind power generators markets in Europe and parts of the US will be hard to pene- trate for the Chinese. Certainly, a few odd orders can come through, but the Chinese presence is unlikely to reach the dominant scale of the solar energy industry,” she says.

Upcoming wind power markets, such as Central and Eastern Europe and Latin America, may find lower equipment costs attractive, espe- cially when coupled with a generous offer of providing project financing, says Bakhareva.

However, proven safety, quality, reliability and after-sales service homemade wind generator may well tilt the scales in favour of Western wind turbine producers, even though the initial investment will have to be bigger, she concludes.

Asia is now the main engine of growth for the global wind turbines industry. In fact, the Asia Pacific region will account for at least 44% of total MW added globally through 2025. With continued logistical, ecological and landuse challenges hindering the development of more wind farms, developers and power producers are increasingly looking offshore as a feasible means of building more wind farms to feed an increasingly power hungry world.

But, building offshore presents challenges of their own, and is a constantly changing field. As companies continue to develop bigger engines that are able to capture more wind, as well as improve transmission and building systems, offshore wind construction is constantly challenged to find ever more reliable foundations and designs, transmission build-out, supply chains and installation methods.

OFFSHORE WIND CONSTRUCTION SUMMIT 2012, 15 – 17 February 2012, ICC Jeju Island, South Korea, will provide you with the perfect platform to address these concerns and more! We will be taking an indepth look at the construction challenges in offshore wind farms and will wind turbine generator be bringing you CASE STUDIES from around the world to address key technological and operational issues when it comes to delivering an offshore wind farm that meets your requriements and needs.

A 49.5-megawatt (MW) wind farm has been constructed in Mouding county, southwest China’s Yunnan province, the local publicity department said Thursday.
China Guangdong Nuclear Power Group constructed the wind farm with an investment of 483 million yuan ($76.7 million) over the past 15 months.
Xinjiang Goldwind Science and Technology Co Ltd (Goldwind) supplied 33 units of 1.5MW permanent magnetic direct drive wind turbines for the project.
The wind farm, based in Fengtun on Dajianfeng Mountain, is 2,000-2,500 meters above sea level in the Yunnan-Guizhou Plateau.
Developing wind farms in high-altitude areas has become a priority for Chinese power companies and wind turbine manufacturers, as both look to exploit rich wind resources on the country’s plains.
“We have tailor-made turbine models featuring larger blades and greater capacities for insulation, heat dissipation and lightening protection, in order to cope with harsher geographical and climate conditions in plateau areas,” said Wu Gang, board chairman of Goldwind.
Other Chinese turbine makers have also shown great interest in developing wind turbines for high-altitude areas.
In November, Chinese wind generator manufacturer CSR Zhuzhou said it had connected high-altitude turbines to the grid at a wind farm in Yunnan province, and that it had orders for 400 of these specially-adapted turbines, marking the largest order in the country.
Longyuan Power and Huaneng Renewables, China’s leading wind farm developers, have targeted southwest China’s Guizhou province for wind power projects. The province is aiming for 9 gigawatts (GW) of wind capacity by 2020.

Guohua Energy Investment will pay $88.6 million for the majority stake.

Hydro’s Roaring 40s joint venture with China Light and Power was wound up last financial year and Hydro took ownership of the two wind farms at Woolnorth in the state’s north-west.

Guohua has more than 20 wind turbine generator farms across China.

The state-owned business also runs the world’s largest coal business.

Energy and Resources Minister Bryan Green says Hydro will continue to operate Woolnorth.

“The fact is that we built partnerships initially to establish the wind farms and now we’re in a position to sell down that proportion but still retain 25 per cent and, at the same time, retain responsibility with respect to the ongoing management of the site which is obviously extremely important.”

Mr Green says the wind turbines firm was chosen because of its expertise in working with Hydro Tasmania on other renewable energy projects.

Hydro chief executive Roy Adair says there were more than 30 expressions of interest and he is happy with the sale price.

Guohua also has an exclusive six-month window to negotiate a share in Hydro’s $400 million Musselroe wind farm project.

“In an ideal world and subject to agreement on the appropriate terms, and that the terms must be agreeable to both sides.”

An independent intellectual property rights, the maximum power of 2.5MW high-speed permanent magnet synchronous wind turbine in the company’s success off the assembly line. Successful development of the generator, marking the Chinese companies already have their own R & D with international advanced level high-speed permanent magnet synchronous wind turbine capacity.

Second Five-Year period, China’s wind power installed capacity of the proportion of total generating capacity will further increase, for the grid security considerations, the small wind turbine must be in the “low voltage ride through” under the protection of “Sailing with wind.” According to the National Energy Research Institute said the person, land-based wind power by 2020 the cost of coal will be flat, then wind power will be gradually out of state subsidies, reduce the cost of a wind power industry is facing the future development of the new “bottleneck.”

South propaganda minister Zhu Jianfei motor vehicle, told this reporter that the generator and the direct drive permanent magnet synchronous wind turbine generator compared to greatly reduce the volume, less weight, in particular, greatly reducing the amount of magnet, rare earth prices remain high in today, the product cost advantages become more prominent, with good market prospects. Meanwhile, the generators with high efficiency, small size, compact, low cost, high reliability, low maintenance and many other advantages, the use of full-power converter control, the unit has good low-voltage ride through performance.

In a vast prairie to the north of Hohhot, the capital city of north China’s Inner Mongolia Autonomous Region, hundreds of wind turbines stand like a vast, unbroken forest.

The turbines have created both opportunities and problems for the region’s power companies.

“I long for wind, but I also fear wind,” says Su Changyou, a manager of a wind farm located in Inner Mongolia’s Siziwang Banner (County).

“During high winds, my wind turbines will rotate in full gear, which means higher profits. But sometimes, my telephone rings with calls from power grid controllers ordering us to limit our power generation,” says Su.

Ever since Su’s wind farm was connected to China’s power grid last May, only about 60 percent of the farm’s turbines have been in operation. The rest of the small wind  turbines must remain idle to avoid overloading the grid.

Qi Laisheng, general manager of the Inner Mongolia subsidiary of Longyuan Power, China’s largest wind farm operator, says “these things happen all the time here. About a quarter of the turbines on my wind farm have to remain idle, even on the windiest days.”

Grid access has become a nightmare for Inner Mongolia’s burgeoning wind power industry. Wind farms in the region have a total installed power capacity of 6.5 gigawatts (GW), the most of any region in China.
