China Suggests Capping Wind Power On-grid Tariffs

China should cap wind power on-grid tariffs in order to bring tariffs set by local governments into line with those set through the national public bidding system, according to a report recently released that was compiled by the National Development and Reform Commission's Energy Bureau.

While the report did not propose any specific price caps, the adoption of such a system would serve as a blow to foreign developers in China's wind energy market who have relied on favorable local on-grid tariffs for small-scale wind power projects in order to generate acceptable profits

Wind generators projects with over 50 megawatts of capacity need to go through a public bidding process, organized by the NDRC, in which low power tariffs are the primary criterion for winning. Tariffs for projects awarded by local governments tend to be RMB 0.1 ($0.013) per kilowatt hour higher than those awarded through the central government's bidding system.

Beijing aims to drive down the price of wind generated power in order to encourage its use, which it believes can be achieved through such a competition bidding system as well as the localization of wind power equipment production.

However, such an approach has benefited deep-pocketed state-owned power companies that have emission-reduction targets to fulfill. Such companies tend to submit uneconomic bids in order to win the project, and then leave the wind farm either undeveloped or equipped with low-quality equipment in order to cut costs.

By going through local governments though, foreign companies can secure better power on-grid tariff rates as well as more control over key aspects of their projects, such as the location of the wind farm. Such important issues can sometimes make or break a deal, Alberto Mendez, the China general manager of Spain's Gamesa, one of the world's largest wind turbine makers and wind farm developers, said at an industry forum held in May.

At present, wind farm projects planned or awarded via tenders by the central government have a combined power generation capacity of 2,000 MW, while those handled by local governments have a combined capacity of almost 8,000 MW.
Industry insiders have long called for a premium rate for wind power that would be set around RMB 0.25 ($0.03) per kWh higher than power from coal-fired plants in order to create further incentives to attract investors.
The report also said that China should adjust its wind turbine development targets at an appropriate time as, if current trends continue, the country is likely to achieve a wind power capacity triple that of its current 2020 target of 30,000 MW.
China could even achieve 120,000 MW of installed wind power capacity by 2020 if the country's policy environment is improved, according to the report.

The NDRC currently expects over 2,000 MW of wind power generating capacity to go into operation this year, adding to the 2,600 MW of wind generators generating capacity that was installed last year.

Of the total capacity added last year, Goldwind from northwestern China's Xinjiang Autonomous Region accounted for 33.2 percent of the addition, followed by Denmark's Vestas, one of the world's largest producers of wind turbines, with 23.5 percent. Gamesa accounted for 15.8 percent of newly installed capacity, while U.S.-based GE accounted for 12.6 percent, according to the China Wind Energy Association.

Hummingbird cost-effective small wind turbines

Small wind turbine is a long-term benefit from an investment of energy products, which generally 10-15 years of life, or even longer, and in a good wind resource areas, 3-year capacity, to recover the full investment costs. After the recovery period, the remaining time for generating all the proceeds, the proceeds of up to 2 times more than investment, so the investment of the product is very cost-effective!

generation small wind turbine costs per unit of electricity (KWH) of about 0.3-0.6 million, which can be seen this value than that of the Municipal Electric electricity is also low! Electricity than the island, much lower! Lower than the oil-generated electricity more!
For example: fuel general generators (medium) of the direct fuel costs about 1.05 yuan / kWh, plus the loss of units, conversion efficiency, small-load loss and so on, electricity costs at least 1.60-2.00 yuan / degree.
Small-scale power generation units of generator fuel costs even higher, and every day with a reduction of resources is bound to a variety of fuel prices rising every day. This shows that the use of small wind turbine is the most practical, most economical and the most cost-effective and best solution to save money. The small wind turbine

This year China will become the world's largest producer of wind turbines

Last year, the Global Wind Energy Council (GlobalWindEnergyCouncil / GWEC) Secretary-General SteveSawyer said that in 2009 China will become the world's largest producer of wind turbines, which will rapidly developing field of renewable energy brought new changes. According to the agency's data, although in 2007 the global wind power accounted for only 1% of the electricity supply, but the rapid development of wind power by 2020 will meet 12% of world electricity demand, and this will go a long way to control global warming benefits.

To deal with global climate change, reduce greenhouse gas emissions, renewable energy sector has attracted more and more and more investment, especially wind power, which provides energy than solar power and bio-energy and other renewable sources of energy to many. According to Sawyer introduction to the end of 2009, China's wind power capacity from the current 400 million to about瓦提high 10 million kilowatts, is the world market of more than half of capacity. 2007 World Added 1700-1900 wind generation capacity 10,000 kilowatts, with a total generating capacity of the fan more than 90 million kilowatts by 2008, 10000w wind generators global fan power generation capacity will be more than 100 million kilowatts.

According to Sawyer said the two Chinese fan wind turbine manufacturer and Huarui Jinfeng have been made in 2009 and 2010 large-scale export scheme, there is no Chinese export fans, but once the Government to promote exports will be the rapid development of the members of this Council (more than 50 countries, more than 1,500 enterprises) on the Chinese fan impact on the world market should be prepared.

At present, the world's largest fan manufacturers are Denmark's Vestas, the other more important producers are Spain's Gamesa, General Electric of the United States, India's Suzlon and Germany's Enercon
