Recently, the National Energy Board to Liaoning, Hebei, Tianjin, Shanghai, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, Guangxi and Hainan provinces, 11 departments issued a circular calling for offshore wind power to declare parts of the concession tender. This indicates that, my first round of offshore wind power concession bidding started.

Notification requirements, project scope for coastal tide of multi-year average high tide line to 50 meters deep offshore waters. According to “first experiment, after the expansion,” the principle of construction, according to wind energy resources, the marine environment, power conditions, such as sending and technical capacity to determine overall project size, a total installed capacity of a single project is tentatively scheduled for 20 to 30 million kilowatts.

Project site provinces (autonomous regions and municipalities) in charge of the energy sector as a project tender people, according to the national energy program approved by the authorities to tender. The project will be online pricing, unit equipment, and construction technology as the main conditions of the tender option investors, local governments responsible for implementing maritime use, network access, market conditions, such as sodium consumption, successful enterprises on the tender conditions and the completion of the project construction tasks.

The project site should be consistent with the marine-use planning, Kamagra and there are detailed wind data, address, hydrographic survey and marine survey data to meet the needs of wind power construction projects. Construction projects must be completed before the pre-feasibility study, the marine management area has been preliminary agreed to the use and environmental impact assessment, and complete network access system design and so on.

In late April 2009, the National Energy Board once issued a circular calling for the provinces to develop offshore wind farm project planning, and in accordance with unified planning, phased construction principles, optimizing the selection of more than a few installed capacity of 1000 MW offshore wind farm sites, proposed phased construction program, and by the region’s power grid companies organizations, the establishment of offshore wind power transmission planning.

Currently the provincial offshore wind farm plan has been basically prepared. On this basis, to start offshore wind power concession bidding will help accelerate China’s offshore wind power development. Taking into account cialis fast delivery the building of offshore wind power is difficult, high cost and the laying of undersea transmission lines need to standardize and other factors, so a single 1,000-megawatt wind farm the size of more than economy.

Shi Pengfei, vice president of Chinese Wind Energy Association also believes that the huge investment in offshore wind power, a single wind farm development of the introduction of a single subject, in addition to reflect the economy, there are also beneficial to developers of investment continuum. This means that those with a strength of developers and machine manufacturers, will be more likely to be involved in offshore wind power development.

According to the National Weather Service preliminary estimates, China’s coastal waters can be installed at about 200 million kilowatts of wind power. Compared with the onshore wind, offshore wind power years, the use of an hour long, the wind speed higher than the land, the wind shear change is small, turbulence intensity is small, the dominant direction of a stable, so unit stable operation, long life and does not require a high tower frame, the energy output of a larger stand-alone. In addition, the offshore wind power do not take up land resources, and close to the load centers along the coast. The development of offshore wind power, can effectively avoid the long-range land-based wind power transmission problems are conducive to wind power sent solution to the problem.

At present, China is only the East China Sea Wind Power Co., Ltd. Shanghai Donghai Bridge Offshore Wind Power and National Power Longyuan Rudong intertidal two offshore wind power projects and power generation, including the finalization of the East China Sea Bridge project after-tax price of 0.978 Internet yuan / kWh, onshore wind power more expensive than the nearly 1-fold.

Shi Pengfei said that to carry out offshore wind power concession bidding, the introduction of market mechanisms will help to further reduce the cost of offshore wind power generation, which is China’s land-based wind power concession bidding a similar path.

In 2003, China began the first phase of land-based wind power concession bidding, to 2008 conducted a total

of five. Through the five bidding greatly reduces the cost of onshore wind power generation, and effectively promote the domestic development of fan manufacturers.

Compared with the onshore wind, offshore wind power in the basic areas such as site selection and hoisting technology is more complex. In general, the success of offshore wind farm development depends largely on five factors: the wind resource assessment, project design, policy incentives, talent pool, electricity access. According to the Pearl River Water Planning Survey and Design Company estimates, in the entire offshore wind farm project, the fans account for only 35% of the total cost and other costs from the construction, installation, prescription cialis generic operation and maintenance, and network management and recycling parts, including the construction 24% installation, operation and maintenance accounts for 22%.

Currently designed for their lack of related design experience in infrastructure design selection can not give the optimal conditions for the domestic site design, well-designed and economy has yet to be tested. In lifting, due to the lack of relevant research, China has not yet suitable for the professional installation of the sea fan vessels, only the help of a number of hydraulic units in the transformation of the vessel for installation. To carry out offshore wind power concession bidding, offshore wind power will be designed to accumulate more experience, to find out the more rational construction method.

In addition, the present, China only Huarui, gold wind and a few other companies can design and manufacture of large-scale power generation for the sea fans, through the concession tender to accelerate the building of large-scale offshore wind power will be for domestic MW class large fan manufacturers to provide greater market demand, accelerate the upgrading of domestic technical level of the sea fan-made.
