Vestas (VWS.CO) said on Friday that EnBW (EBKG.DE) had picked its new turbine, which will be the world’s biggest, as the preferred option for the 900 MW He Dreiht project in the German North Sea, which will be operated without subsidies.
Colossal turbines, which will dwarf many skyscrapers, are key for the offshore wind industry to remain profitable after countries phase out subsidies that have defined the green industry since the 1990s.
“In a time where the whole world is talking about how we address the energy transition, this is one of the important answers: that you can have a levelised cost of energy that is below gas, oil, nuclear,” Vestas’ chief executive Henrik Andersen told Reuters, referring to the cost of an installation over its lifetime divided by the power it produces.
Big wind turbines are more efficient, meaning fewer units and lower costs.
Vestas’ 15 MW turbine will be the world’s largest when it comes into use in 2024. With a wingspan of more than 230 metres, the turbine will sweep an area of 43,742 square metres – roughly the size of six soccer pitches – and have capacity to power 20,000 households.
