It is not yet ripe to vigorously develop offshore wind power

Recently, China's National Energy Administration approved the "Hebei Province Offshore Wind Farm Project Plan" and agreed that Hebei Province's offshore wind farms will be planned and constructed with a total installed capacity of 5.6 million kilowatts, including 4.3 million kilowatts in the Tangshan region and 1.3 million kilowatts in the Ganzhou region.

With the opening of the International Offshore Wind Power and Wind Power Industry Chain Conference in early June, the topic of offshore wind power has returned to public view.

When wind power on the land was basically divided, more companies began to look toward the offshore wind market in China. On the one hand, there is not yet too much new wind power for offshore development, while the related technical and policy issues have not been implemented. For China's offshore wind power, it is really "it is not easy to say love you."

The time is not yet ripe According to the Global Wind Energy Council, as of 2011, the new installed offshore wind farms in the world are mainly concentrated in China and Europe. The total installed capacity of offshore wind power in the world reaches 3,980 megawatts, of which the total installed capacity of offshore wind power in China is 209.9 megawatts. In 2011, the global installed capacity of offshore wind power was 470 MW, of which China added 107.9 MW, accounting for 22.96% of the total.

At present, China’s offshore wind projects that have been completed and put into operation include the 102 MW offshore wind power project of Shanghai Donghai Bridge and Guodian Longyuan’s Jiangsu Rudong Intertidal Intertidal Hurricane Wind Farm.

However, the tender for the first phase of China's offshore wind power concession has not yet been approved. The second phase of the tender has no news.

There are still many constraints on the development of offshore wind power. As we all know, the development of offshore wind power requires high technology, but China's current offshore wind power technology is not mature and lacks engineering and technical experience. It is understood that the manufacturing of large-capacity turbines with a capacity of 5 MW or more suitable for offshore wind power construction is still in the stage of prototype development and experimental testing. There is a lack of construction equipment that can adapt to a variety of construction conditions, and the design and construction of offshore wind turbines is insufficient. Offshore substations and submarine cables also have lower transmission levels.

In addition, some small and medium-sized private technology companies are not easy to carry out scientific and technological innovation research. A considerable part of the R&D expenditures of some enterprises are in foreign countries, and it is difficult to meet the requirement that the proportion of overseas R&D expenditures for high-tech companies does not exceed 40 percent, and therefore it is not supported by large national research projects.

Take Jiangsu Yuanjing Energy as an example. Although the fans produced by the company are recognized by many leading global wind farm developers, foreign banks have not cooperated with them before and they are unwilling to provide loans for purchasers of prospective wind turbines, leading to these international buyers. It is difficult to choose a distant wind turbine.

They hope that the government can guide financial institutions such as the National Development Bank and the National Export-Import Bank, and provide project owners with financing for the overseas expansion of smart companies.

Moreover, at present, China's offshore wind power technical specification system is still not perfect. Offshore wind power has no corresponding standard system, and it is difficult to effectively guide engineering exploration, construction and installation, operation and maintenance, and it lacks effective management of offshore wind power technology and economic risks.

“The development of offshore wind power in China is still a long way to go. Offshore wind power projects have high construction costs and high maintenance costs. They are now being piloted and are still not able to develop on a large scale. In order to develop offshore wind power in China, we must first introduce more advanced foreign experience. Then he sought innovation,” Lin Boqiang, director of the China Energy Economic Research Center at Xiamen University, said in an interview with the China Economic Times.

Before the meeting, the Chinese Academy of Engineering Academician Ni Weidou, chairman of the China Energy Association, also said: “The main force of the wind power market is still on the land, and it has not yet been time to develop offshore wind power. Sinovel Wind Power (601558) Offshore Wind Power Project Running for such a long time, from the point of view of operational effectiveness, it is also 60 points, and it is certainly a loss to give no preferential policies.

It is understood that the 100,000-kilowatt offshore demonstration wind farm at the Shanghai Donghai Bridge built in June 2010 is known as the only offshore wind farm built and put into operation outside of Europe, and the first offshore wind farm in China. The 34 3MW units installed were provided by Sinovel.

Industry insiders frankly stated that the Donghai Bridge project is actually a guise. It is forced to "drive water" by land-based wind turbines. It can't be used stably after getting up. The utilization rate is very low. It often shuts down and a lot of money is spent there. Sunbathing."

At the same time, Shanghai admitted that as the first offshore wind farm to eat crabs, the price is too high from an economic point of view.

According to the “Twelfth Five-Year Plan”, wind power on land is developing steadily. Offshore wind power is a demonstration development. In 2015, China will build 5 million kilowatts of offshore wind power and build 30 million kilowatts by 2020. And in 2020, the goal of the entire Europe is 40 million kilowatts, and the U.S. target is 10 million kilowatts.

However, Shi Pengfei, deputy director of the Wind Energy Committee of the China Renewable Energy Society, expressed concern that he said: “These problems encountered in the development of offshore wind power in China require the coordination of various provincial governments. According to the current progress, up to 2015 The 10,000 kilowatts of offshore wind power installation targets are all at stake."

Ni Weidou's point of view is similar to that of Shi Pengfei. He said: “The demonstration is that we should not be aggressive and should not have explosive growth. I think offshore wind power is 2 million kilowatts. It is not necessary to develop so fast within 5 years. After 5 years, it will be hard to say whether offshore wind power will blow out. This depends on how cost, resource surveys, and corrosion and maintenance issues are addressed. The next step is to discuss development."

In fact, in July last year, the National Energy Administration and the State Oceanic Administration jointly formulated the Implementation Rules for the Interim Measures for the Management of Offshore Wind Power Development and Construction to further regulate the development of offshore wind power. This year, the "Twelfth Five-Year Plan for Wind Power Technology Development" issued by the Ministry of Science and Technology also clearly stated that during the "12th Five-Year Plan" period, China will continue to develop large-scale offshore wind power. For this reason, during the 12th Five-Year Plan period, while China is building six million-kilowatt wind power bases on land, it will also build two 20-million-kilowatt offshore and coastal wind power bases.

"We are worried about the development of offshore wind power. Although there is no batch installation, we have developed offshore wind power equipment and have plans to accelerate the production of offshore wind turbines," a Beijing-based wind power equipment company official told the China Economic Times.

Daikin Heavy Industries (002487) also made it clear that “the offshore wind power has broad prospects and the company will directly benefit in the future. Faced with huge development opportunities in offshore wind power, the company decisively chose to establish a sea-based base in Penglai and lay out 50,000 tons of offshore. Wind power production capacity has made positive preparations for the company to actively enter the offshore wind power market."

"However, we also have concerns that if there is a lack of planning, wind power-related companies will make a leap forward, and 'staking their claims' will also easily appear in offshore wind power," said the wind power equipment company.

This worry is not unreasonable, but it has been taken seriously. According to Liang Zhipeng, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, in order to avoid disorderly development, in principle, an area of ​​offshore wind power will be developed by one entity and the right to examine and approve offshore wind power projects will remain in the national development and reform. The committee prohibits local governments from independently approving offshore wind projects.

"China's offshore wind power development is still in a period of growth. It falls between technology and cost, and it's still far behind in the race." Ma Xuelu, deputy director of the China Wind Energy Association, said in an interview with this reporter.
