"It is estimated that by 2015, China's offshore wind power capacity will reach 5 million kilowatts, and it will reach 30 million kilowatts by 2020." The National Energy Administration or the second round of offshore wind power concession bidding will be launched in the first half of next year. 2 million kilowatts, more than double the first round of tenders. This is an encouraging news from the “Shanghai International Offshore Wind Power Conference 2011” held in Shanghai yesterday. There are indications that a feast of offshore wind power is about to begin.

The China Resources Comprehensive Utilization Association's Renewable Energy Committee and Greenpeace released the “Windscape - China Wind Power Development Report 2011” (hereinafter referred to as the “Report”) on June 16. It shows that offshore wind power has become the focus of global attention, on the one hand, because Europe The onshore wind power resources in various countries have been almost fully developed, and expansion of the wind power industry for the offshore industry will once again set off an upsurge in the enclosure. On the other hand, as the technical difficulties in offshore wind power are repeatedly broken, this increasingly mature industry gradually attracts more and more Financial support.

Yi Yuechun, deputy chief engineer of the Hydropower and Water Conservancy Planning and Design Institute, introduced at the meeting that since its inception in 2007, China has built a total of 142,500 kilowatts of offshore wind power capacity, which is initially capable of offshore wind power design, construction and equipment manufacturing. It is estimated that by 2015, the installed capacity of offshore wind power in China will reach 5 million kilowatts, and it will reach 30 million kilowatts by 2020.

The report also pointed out that in the next five years, the acceleration of offshore wind power development will be a common judgment in the industry, but offshore wind power development is technically difficult and is subject to restrictions on offshore wind power development resources and technical conditions. Offshore wind power is mainly concentrated in Europe and China. It is generally estimated that by the end of 2015, European offshore wind power will account for 20% of its cumulative installed capacity of wind power, that is, about 36GW, and China will be around 5GW. Even so, offshore wind power will only account for the total installed capacity of global wind power by 2015. About 7%.

Song Liang, an analyst at the China Center for Circulation Productivity Promotion, believes that the previous round of tender prices was generally low, and the final four items had a winning bid of 0.6 to 0.7 yuan/kWh. This price has already approached the benchmark on-grid price of wind power on the road.

In addition to the high cost, offshore wind power must also face the common problems of the wind power industry in connection with the network and weak technology. “The problems encountered at sea will be more than land, because the cost of installation, transportation, and operation and maintenance of offshore wind turbines is higher, and the operational environment of offshore units is also more demanding than land.” Song Liang said.
