The largest single onshore carbon fiber blade wind power project in China has been officially put into operation

On September 14th, China's first large-scale single unit wind power project using 10 MW generators, the Inner Mongolia Energy Urad Middle Banner 1.5 million kW wind storage base project, was officially put into commercial operation. The project uses a total of 150 10 MW wind turbines, of which 110 are from Sany Heavy Energy (688349), and the wind turbines use all carbon fiber blades.

Pengpai News learned from Sany Heavy Energy that all carbon fiber blades are more lightweight, which can help the unit achieve better loads. At the same time, the blades of wind turbines are farther away from the tower, which also helps improve operational safety.

It is reported that the wind turbine in this project adopts all carbon fiber blades, with a larger root diameter of 3.6 meters and an increase in root bearing capacity of over 26%. When the fan is running, the distance between the blade tip and the tower increases by more than 12%, greatly increasing the safety of the blades. At the same time, the wind turbine unit of this project adopts a 1.7-meter main bearing, which has obvious advantages in width and thickness, with a bearing capacity increase of more than 20%, and the overall safety performance of the unit has been significantly improved.

Carbon fiber is known as the "king of new materials" and is a new type of fiber material with high strength and high modulus. It has strong corrosion resistance and excellent mechanical properties. In the field of wind power, carbon fiber is mainly used in the main beam of wind turbine blades. As of the end of 2024, the annual production capacity of carbon fiber in China has reached 135500 tons, and the demand for carbon fiber in wind turbine blades accounts for about 38%.

Sany Heavy Energy also stated that the wind turbine host of the project has two additional "ears" on both sides. This is Sany Heavy Energy's innovative box type transformer side placement technology, which optimizes the load capacity of the unit. By using stronger double bearings, the transmission chain runs more stably and reliably, while reducing the weight of the unit by more than 5%.

According to Inner Mongolia Energy Group, after the project is put into full capacity operation, it is expected to generate 5.44 billion kilowatt hours of electricity per year, reduce standard coal combustion by about 1.64 million tons per year, and reduce carbon dioxide emissions by about 4.98 million tons.
