Offshore wind turbines keep getting bigger

Wind turbines keep getting bigger and more powerful, making wind energy cheaper and more competitive with traditional fossil fuels.

According to WindEurope, the turbine capacity has increased on average by 16% every year since 2014. In 2019, an average turbine produced 7.8 MW, 1 MW more than in 2018.

The increase in power comes with an increase in rotor diameter, with longer and more aerodynamic blades, as well as constant improvements in power generation, hardware, and software.

Industrial leaders like Siemens Gamesa and GE already revealed 12-megawatt and even 14-megawatt models with rotor diameters over 220 meters.

Euronews visited the heavyweight terminal at the port of Ostende, in Belgium, used by Siemens Gamesa to install 58 of its 8.4-megawatt turbines at the SeaMade offshore windfarm nearby.

Jan Claes, senior project manager at Siemens Gamesa, showed us around:

“These blades have a length of 81.4 meters. The largest width is about 5.4 meters.

“We need more and more green energy. So the bigger they are, the more surface they take, the more energy we can produce.

“Power is one thing where turbines are getting better all the time, and then in the turbine itself, there’s a lot of technology, a lot of investment in research to get them better and better – meaning that there are fewer components. Fewer components are less maintenance, it’s also fewer things that can break down.

“The future, I think, looks bright for wind power. There’s a lot of demand worldwide. Today, Siemens Gamesa only – our company only – we have more than 50 gigawatts of turbines worldwide installed. And the demand is still growing. Green energy is the future for our children and grandchildren.”
