Vestas and its mega-machine pre-selected tenderer for EnBW’s He Dreiht
Potentially this could be the first commercial deployment of the new V236-15.0 MW wind turbine
Vestas reports that it has been named the pre- selected tenderer to supply the wind turbines for EnBW’s 900 MW He Dreiht project. If a firm and unconditional order is eventually signed, this will mark the world`s first commercial deployment of the new V236-15.0 MW offshore turbine. This means that “this highly advanced turbine type has made its mark after only five months on the market”, notes Vestas. Vestas was pre-selected through an EU tender process to provide V236-15.0 MW turbines for installation at the project in 2025. The He Dreiht wind farm site is located in the German North Sea within 85 km of the island of Borkum and 104 km west of the island of Helgoland.
“With the industry’s largest swept area and a capacity factor of over 60% from the 115.5 m blades, the V236-15.0 MW turbine will deliver industry-leading park performance for EnBW at He Dreiht”, says Vestas.
The swept area of the turbine is 43 742 m2 and depending on site-specific conditions, a single V236-15.0 MW turbine is capable of producing 80 GWh per year, the company estimates.
With the new machine, “Vestas is resolutely back in offshore wind”, said Henrik Andersen, president & CEO of Vestas.
Nils de Baar, president of Vestas Northern & Central Europe, added: “Germany’s offshore wind ambitions for 20 GW by 2030 will require ground-breaking projects and technology, such as the V236-15.0 MW turbine.”
The He Dreiht project will be operated on a subsidy-free basis by EnBW, highlighting “the

attractive turbine solution” being provided by the V236-15.0 MW platform, says Vestas. “If and when the agreement with EnBW materialises”, Vestas says installation of the turbines could begin in the second quarter of 2025, with full park commissioning anticipated for the fourth quarter of 2025. EnBW says it
expects that the contract with Vestas will be finalised by the end of 2021. However, it also says a final investment decision will not be taken until 2023.
“Ten years ago, offshore wind energy in Germany was still in its infancy. Back then, we built Baltic 1, which was Germany’s first commercial offshore wind farm in the Baltic Sea”, recounted Dr Georg Stamatelopoulos, COO generation at EnBW. Since then, turbine unit output has increased more than six-fold, he observed.

EnBW secured the He Dreiht project in the 2017 German offshore wind tender. “Offshore wind power is not only technically challenging,” says Dr Stamatelopoulos, “we have to go into the auctions with wind turbines that are not yet on the market at the time of the planning stage. There is no crystal ball here: the only answer is sound technical forecasting and knowledge of the market. And we made the right choices as project developers, as the outcome shows. We are going to use the most advanced and cost-efficient turbine technology, which means we can install He Dreiht without any subsidies.”
