China unveils world's largest wind turbine

Last year, General Electric unveiled a wind turbines 248 meters in diameter and 220 meters in diameter (see our previous article below). A record has already been surpassed, with the announcement on August 20 of the Chinese company MingYang smart energy and his MySE 16.0-242 turbine. With a capacity of 16 megawatts, this Giant wind turbines It has a diameter of 242 meters, a feather length of 118 meters and an area of ​​46,000 square metersair, equivalent to six football fields!

« One of these wind turbines will be able to supply 80,000 megawatt-hours per year, which is enough to supply electricity to 20,000 homes.Manufacturer welcomes. It will prevent the release of 1.6 million tons of carbon dioxide2 annually and presents a Duration Age 25 years. »

There does not seem to be any limit to gigantism from offshore wind turbines. It must be said that the gainenergy More than proportional: With the rotor only 19% larger, 45% of the electricity is produced. In addition, with fewer wind turbines for the same power, installation and maintenance costs are reduced. maintenance. According to the study nature energyGiant wind turbines can cause wind energy prices to drop Navy From 37% to 49% by 2050.

One cycle of this wind turbine saves electricity for the family for two days

Haliade-X turbine from Generel Electric, The largest in the world, recently upgraded from 12 MW to 13 MW. “Its blades that are 107 meters long will be able to generate 4% more energy than before,” I assure GE Who quotes amazing characters on his wind turbines. with him mast 248 meters high and 38000 meters high2 From the surface swept by blades, the latter broke a record of 312 megawatts in one day, which means that one cycle can power a British home for two days! If we compare this figure with the electricity consumption of a house of 50 square meters in France (30 kWh), then this is 8.3 seconds of operation.

Of course, this is a record and the turbine does not operate at full power every day or all the time. This improved version of the prototype, which has been successfully operating in Rotterdam since November 2019, will be installed in the first two stages of the Dogger Bank wind farm In the UK, with a total of 190 units installed as of 2023. It will become the largest offshore wind farm in the world. Serial production of the Haliade-X platform will begin in the second half of 2021 at GE’s plant in Saint-Nazaire, France.
