On September 26, 2007, the installed wind power capacity exceeded 1 million kilowatts, becoming the first domestic wind power enterprise to exceed 1 million kilowatts.
In August 2008, the installed wind power capacity exceeded 2 million kilowatts.
In September 2010, the world's first intertidal zone test wind farm was built in Rudong, Jiangsu.
In October 2010, the installed wind power capacity exceeded 5 million kilowatts.
In May 2011, China’s first large-scale low-wind speed wind farm was built in Lai’an, Anhui.
In November 2012, an intertidal zone demonstration wind farm with an installed capacity of 150,000 kilowatts was built in Rudong, Jiangsu.
On December 28, 2012, the installed wind power capacity exceeded 10 million kilowatts.
In September 2013, we successfully won the bid for two wind power projects in South Africa, totaling 244,000 kilowatts.
On November 3, 2013, the world’s highest wind farm—Longyuan Tibet Nagqu High Altitude Experimental Wind Farm—was built in Nagqu, Tibet.
In November 2014, the first overseas project, a 100,000-kilowatt wind farm in Canada, was put into operation.
On December 31, 2014, the installed wind power capacity reached 13.543 million kilowatts.
On June 30, 2015, the installed wind power capacity reached 14.568 million kilowatts.
The investment amount, power generation and economic benefits of offshore wind power projects will be affected by many factors, such as the water depth of the location, wind speed, equipment selection, construction period, policy subsidies, etc. Therefore, it is impossible to give an accurate answer. The following only provides a rough reference:
1. Investment amount: The investment amount for 1GW of offshore wind power is usually more than billions of dollars. The specific investment amount depends on the project location, equipment selection, construction period and other factors.
2. Power generation: The power generation of offshore wind power is related to the water depth, wind speed, wind energy density and other factors of the location. Generally, a 1MW offshore wind turbine can generate about 25-35 million kilowatt hours per year. Therefore, a 1GW offshore wind power project can generate an average of about 25-35 billion kilowatt hours per year.
3. Economic benefits: The economic benefits of offshore wind power include power income, policy subsidies, carbon emission reduction and other factors. Generally speaking, the investment return cycle takes several years to more than ten years, depending on factors such as the investment amount of the project, policy support, and power market prices.
It should be noted that the above data are for reference only, and specific data need to be evaluated based on actual project conditions.
