The hottest offshore wind power development encoun

The development of offshore wind power has encountered a planning "bottleneck"

the author learned from the Jiangsu Provincial Energy Bureau and the Bureau of ocean and fisheries that one year and eight months after winning the bid, our province is also one of the first batch of offshore wind farm projects in China that have generally encountered a planning "bottleneck", and so far no construction has been started. The reasons for the "bottleneck" are concentrated in: the pre siting of wind farms, the laying of submarine cables, the existing traffic channels in military areas, and the overlapping of aquaculture reclamation areas. Relevant departments are assisting Jiangsu Haihai Longyuan, Shandong Luneng, Huaneng new energy and other development enterprises to speed up the adjustment of the original plan, strive to pass the national examination and approval, and start construction as soon as possible

due to abundant resources, high utilization of power generation hours, no land occupation and suitable for large-scale development, offshore wind power is the new focus of the global wind power industry, and China is also accelerating its entry into the offshore wind power market. Thanks to 954 kilometers of coastline, abundant wind energy resources along the coast, and complete electricity, our province has become the first province in China to develop offshore wind power on a large scale. According to the plan, the exploitable wind power resources in the province are 21million kW, including 18million kW offshore. So far, more than 90% of the country's offshore wind farms are located in the waters of our province, including the intertidal zone and offshore

according to Chen Yong, deputy director of Jiangsu Provincial Energy Bureau, according to the type of approval, at present, offshore wind farms in our province are mainly divided into concession bidding and demonstration projects. As of February 17, 2012, our province has gathered only four concession bidding projects in China, with a total installed capacity of 1million kW, which are located in the coastal Sheyang sea area of Dongfeng, Dongtai. The national demonstration projects are located in sea areas such as dongxiangshui. According to the national wind power development master plan, 10million kW wind power bases will be built in the coastal areas of our province by 2020, of which offshore wind power will be the focus of future development

"however, at present, the offshore wind power projects in our province have planning defects in different aspects and degrees." Li Rongjun, director of the sea area division of Jiangsu Provincial Oceanic and Fisheries Bureau, told the author that Shandong Luneng's original planned location of the Dongtai concession project overlapped with the coastal aquaculture area, so it had to adjust 10 kilometers to the deep sea, which has now been approved; Guodian Longyuan Power won the bid for Jiangsu Dafeng 200000 kW project, but the project was faced with local overlap between the wind farm and the planning of Jiangsu reclamation area and the rare bird Reserve reported by Jiangsu Province, and the commencement of the project had to be delayed. In addition, the 200000 kW concession and 300000 kW demonstration projects of Jiangsu Haihai Longyuan and Huaneng in Dafeng need more than 1 km, but the sea area involved the main channel of Dafeng port and the reclamation and breeding area, so the plan was not approved. The latest proposal is to build a 10 kilometer wide offshore cable channel along the coast of Dafeng, which is enough to accommodate 4million kW of cables. In this way, the cable can not only have enough space for placement, but also make the cable not spider like at sea, affecting shipping, reclamation, etc. Among the demonstration projects, the offshore wind power project developed by Changjiang new energy in Xiangshui overlaps with the route from Shanghai to Lianyungang, affecting shipping. This problem is also being coordinated

a report from China Hydropower Engineering Consulting Group shows that the first phase of offshore wind power project will be completed at least until 2013. In this context, the highly anticipated second round of offshore wind power bidding is hopeless to start this year. In addition to involving the planning of multiple departments, it also faces the post manufacturing problems of spring production, such as high development costs and difficult technology. Industry insiders said that although the manufacturing level of wind turbines in China has been greatly improved, there are still many difficulties in offshore installation technology, the use of relevant materials, professionals and so on. More importantly, the project involves the national development and Reform Commission, energy, marine, transportation and other government departments, and the coordination between departments is not sufficient, and the project planning is not perfect, resulting in many uncertainties in the work. In addition, the report on Marine Functional Zoning in Jiangsu Province has not been officially released so far, and the development enterprises and relevant departments have no evidence to find in the project operation, which is also an objective factor that makes the operation of offshore wind power projects difficult
