Vestas presents the largest offshore wind turbine in the world: blades of 115.5 meters and production capacity of 80 GWh per year
Danish manufacturer Vestas has a new turbine, and says it is the largest in the world and with the largest swept area. With 115.5 meter long blades, the V236-15.0 MW turbine takes away from Haliade-X de GE the throne of being the most gigantic of all.
Two and a half decades ago, when Vestas started in the wind power business, it was designing 500 kW V39 units. Now things have changed, this technology has evolved so much that it produces turbines with 15 MW. Is found in a constant career of improvement with the American GE, which with its Haliade-X reaches 14 MW.
As announced by Vestas, the new wind turbine has 115.5 meter long blades and a swept area of 43,742 m2. The total diameter of the rotor is 236 meters. Intended for offshore installation, this gigantic wind turbine says Vestas is rated “to withstand extreme wind conditions IEC 1 up to 50 m / s and IEC T up to 57 m / s.”
But since the technical numbers don’t say much, it’s best to compare it in context to see what it’s capable of. Vestas estimates that it can provide around 80 GWh of energy per year. This, of course, as long as the weather conditions are right. With this capacity each turbine could provide energy for around 20,000 European households per year.
If we go to dates, the company expects the first V236-15.0 MW prototype to be built in 2022. Two years later, by 2024, they hope to be able to mass-produce them. V236-15.0 MW is designed with a useful life of 25 years.
The wind future
The future of energy used by humanity appears to be a future of renewable energy. For the first time in 2020 in fact in Europe renewable energies outperformed fossil fuels. In Spain in particular he also has the throne while in UK they consider that by 2030 all British households depend on it.
With wind power too there are the most curious situations, as for example that a season of strong winds gets reduce the price of electricity to historical lows. But if there is something curious and fascinating, it is of course how they are transported from their place of manufacture to the place of installation: ships bigger than a football field and extremely long trucks.
