Offshore Wind Power Becomes New Direction for Wind Power Development

China is rich in offshore wind energy resources and has the resources to develop offshore wind power on a large scale. Under the promotion of various national policies, offshore wind power will enter a period of rapid development and large-scale development. With the completion of high-quality wind resources on land, major power groups will inevitably turn their attention to low-speed wind farms, which will be the trend of industrial development. Some experts believe that in the future, offshore wind power and low wind speed wind farms will become the development direction of China's wind power industry.

At present, the development and utilization of low-speed wind power in China has entered a stage of rapid development. Many domestic wind farm operators are actively promoting low wind speed wind power business, and low wind speed wind power has become a popular wind power development and utilization method that can go hand in hand with offshore wind power. The prospects are very broad.

Sea wind cake seductive

After years of doubling growth on land-based wind power, the pace of development seems to have become stronger.

However, in line with onshore wind power, offshore wind power will usher in the "golden decade." After land-based wind power has been deprived of land, enterprises have turned their sights on the development of wind power to the sea. The economic development of the coastal areas and the large demand for electricity are also one of the considerations for the development of offshore wind power by the Chinese government.

After the rapid growth of land-based wind power, they all transferred the "battlefield" to offshore wind power.

Offshore wind power development is a new phenomenon in the world. In the "12th Five-Year Plan" energy development plan and special plan for renewable energy, the development target of offshore wind power is proposed. In 2015, 5 million kilowatts will be built, and 30 million kilowatts will be built in 2020.

In 2010, after the country began to crack down on offshore wind power, major developers have “snails around the sea” to divide their spheres of influence. Investors frequently approached the local government. In addition to the four companies that won the bid, developers from the Three Gorges, Chinese Hydro, China Guangdong Nuclear Power, Guohua and Huaneng seized nearly 2 million kilowatts of offshore wind energy development resources.

“Compared with onshore wind power, offshore wind power is close to conventional power load centers, which facilitates grid consumption and eliminates the trouble of long-distance transmission.” Shi Pengfei, vice chairman of the Wind Energy Professional Committee of the Chinese Renewable Energy Society, believes that the wind resources of offshore wind power Compared with onshore wind resources, its stability and adequacy are unmatched by wind power on land. Once offshore wind power breaks through technological bottlenecks and realizes large-scale production capacity, its economic benefits will be better than onshore wind power.

At present, China’s offshore wind power is still in its infancy. During the “Twelfth Five-Year Plan” period, a total development scale of 1.5 million to 2 million kilowatts will be planned annually to actively and steadily promote offshore wind power development and promote offshore wind power technology advancement in unit manufacturing and engineering design. The entire industrial chain such as construction, installation, operation and maintenance fosters offshore wind power engineering and technological capabilities to improve the overall competitiveness of the offshore wind power industry.

“Offshore wind power is definitely the future development trend. Now we have adopted offshore wind power as the company’s development strategy.” Zhang Chuanwei, chairman of Mingyang Wind Power, said in an interview with the media that it is not only purely to provide wind power equipment, but they will also provide the selection from wind power. The overall solution for the site, construction and operation and maintenance of the later stage.

However, some experts worry that this is both a challenge and an opportunity for domestic companies. China's offshore wind power has just started and has a good start. Although its development prospects are very good, its development is far more difficult than onshore wind power. There are still many problems to be solved. Compared to onshore wind power construction, there is a concept of window period for offshore wind power construction. Land wind speed can be lifted as long as it is lower than a certain speed. The sea is not the same. There is no wind today. There is a wind tomorrow. The ship goes out again and is suitable. The installation time at sea only accounts for 1/3 of the whole year. Therefore, various construction schedules are arranged according to the window period, otherwise the construction schedule will be extended and the cost will be increased.

According to the preliminary results of the detailed investigation of wind energy resources by the China Meteorological Administration, the installed capacity of wind power in offshore areas within China's 5 to 25 meter deepwater line and 50 meters above sea level is approximately 200 million kilowatts. Under the background that land-based wind power resources have been almost "dispelled," offshore wind power has become a tempting cake.

The low wind speed wind field became the "sweet scent"

“The country’s policy support for the development of low wind speed wind power has become increasingly clear. In the next few years, China will usher in the peak period of low wind speed wind power development.” Industry insiders commented on this, and wind power operators seize opportunities for development of wind power resources in low wind speed regions. Open up a vast market of onshore wind power following the large-scale wind power base.

At present, the development and utilization of low-speed wind power in China has entered a stage of rapid development. Many domestic wind farm operators are actively promoting low wind speed wind power business, and low wind speed wind power has become a popular wind power development and utilization method that can go hand in hand with offshore wind power. The prospects are very broad. At present, the area of ​​low wind speed resources available nationwide accounts for about 68% of the national wind energy resources, and both are close to the receiving end of the grid load.

Previously, domestic wind power development was concentrated in high wind speed areas with abundant wind resources such as northwest, northeast, north China, and southeast coast. Wind power development in low wind speed areas was in its infancy. In this regard, Ai Jian Securities, chief analyst of the power equipment and new energy industry, said that the wind resources in high wind speed areas have been relatively saturated, low-speed wind power market space will reach 80 billion.

“In the future, China will no longer blindly develop large-scale wind power bases, but will strongly encourage decentralized development. This means that the development of low wind speed wind farms near the load center will usher in a huge market space.” China Wind Energy Professional Committee of the Renewable Energy Society He Dexin, director, said that strengthening the development of low wind speed wind power has been incorporated into the '12th Five-Year' wind power development plan, and the policy intends to increase its proportion in the overall wind power development layout in the future.

Many wind power operators have also seen business opportunities in low wind speed wind farms. Longyuan Power, Guodian United Power and Huadian have all been involved in the development of low wind speed wind farms.

To be sure, the future will increase wind power installed capacity in low wind speed regions. As an effective complement to the development pattern of power grids outside the large-scale access to large-scale power grids, these province-area development targets for the development of low-speed wind projects are expected to increase from less than 10% to 20%, and are encouraged to be dispersedly connected to the power grid. This means that China’s “12th Five-Year Plan” put forward a target of 100 million kilowatts of wind power installed capacity, and there will be at least 20 million kilowatts of wind power development.
