Vestas 15-MW Mega Turbine: EnBW Offshore Wind Farm He Dreiht Produces First Electricity
Karlsruhe (Germany) - Germany’s currently largest offshore wind farm, He Dreiht, has produced electricity for the first time. Operator EnBW connected the first of a total of 64 wind turbines to the grid yesterday. With this first kilowatt-hour, an important milestone on the way to full commissioning in summer 2026 has been reached.
He Dreiht gathers pace: Commissioning progressing rapidly
With a total capacity of 960 MW, He Dreiht will be able to supply electricity to around 1.1 million households on a calculated basis. The 15-MW turbine from Vestas is being used here for the first time. One rotor revolution is enough to supply four households with electricity for an entire day.
“The first kilowatt-hour produced by our He Dreiht offshore wind farm marks a significant milestone for EnBW. Boasting a total output of 960 megawatts, He Dreiht is currently Germany’s largest offshore wind farm and a stunning example of how we are shaping the future of sustainable energy. EnBW has been planning, building and operating offshore wind farms in Germany and Europe for over 15 years, playing a key role in helping to meet Germany’s climate change mitigation targets,” said Peter Heydecker, Board Member for Sustainable Generation Infrastructure at EnBW.
World premiere: Vestas 15-MW turbine - internal park cabling and converter connection completed
The new 15-MW turbine from Vestas is being used at the He Dreiht offshore wind farm. “The 15 MW turbine is a world first in terms of technology, setting new standards in offshore wind power. Its efficiency and performance enable a significant increase in energy yield per turbine. Wind energy has the ability to lower power prices, strengthen energy security, and bolster economic prosperity,” said Nils de Baar, President of Vestas Northern & Central Europe.
The internal park cabling and the connection to the converter platform of transmission system operator Tennet have already been completed, allowing the electricity generated to be transported directly to shore via high-voltage direct-current transmission lines.
About the He Dreiht offshore wind farm
The He Dreiht offshore wind farm is being built in the German North Sea, around 85 kilometers northwest of Borkum and 110 kilometers west of Helgoland. With a total capacity of 960 MW, He Dreiht is the largest offshore wind project in Germany. A total of 64 modern wind turbines of the type V236-15.0 MW are being installed. Once fully commissioned, the project is expected to generate around 3.6 billion kilowatt-hours annually.
The He Dreiht offshore project is being built without government subsidies and outside the EEG regime. It involves investments of around 2.4 billion euros and is 49.9 percent owned by a consortium consisting of Allianz Capital Partners, AIP, and Norges Bank Investment Management.
