China will build a giant wind turbine as tall as a 70-story building

In China plan to build a huge wind turbine the height of a 70-story building. MingYang Smart Energy’s new turbine, named MySE 18.X-28X, surpasses the MySE 16.0-242 wind turbine under construction and the world’s largest 18MW H260-18MW from CSSC Haizhuang in terms of output and size.

When the 128m long H260-18MW blades form a circle with an area of ​​about 53,000m2then the MySE 18.X-28X wind turbine with a capacity of “more than 18 MW” The length of the leaves is 140 m, and the area formed during the rotation of the circle is 66,052 m2.

MingYang said the new wind turbine will handle the most extreme weather conditions in the ocean, including super-powerful Level 17 typhoons with winds exceeding 56.1 m/s (202 km/h). According to the company, with an average wind speed of 8.5 m/s (30.6 km/h), it will produce 80 GWh of energy per year. This amount of electricity “sufficient to supply 96,000 men”.

The trend towards building huge wind turbines can be explained by the fact that the majority of the installation costs are incurred by arranging the foundation on the seabed. The greater the output of the wind generator, the lower the proportion of semi-fixed costs per unit of electricity generated.

Compared to 13MW models, the higher capacity of the MySE18.X-28X will save the installation cost of 18 units required for a 1GW wind farm, which MingYang said would reduce the construction cost by $120,000-$150,000 per megawatt lowers. As a result, savings of 120-150 million US dollars could be achieved in the construction of such an object, but this accounts for only 1-2% of the total cost of the project. For reference, the cost of the 1.2GW Hornsea One wind farm with 7MW turbines is estimated at no less than US$5.153 billion.
