The largest offshore wind farm in Scandinavia has officially opened off the coast of Denmark.  

The Horns Rev 3 wind farm, operated by the Swedish power company Vattenfall, is located in the North Sea 25-40 kilometers off Denmark’s west coast. It consists of 49 wind turbines generating a cumulative 407 megawatts of power per year. Each of the 8.3 MW MHI Vestas turbines stands 187 meters and weighs close to 1,500 tonnes including foundation.

The project was inaugurated last Thursday by HRH Crown Prince of Denmark accompanied by Danish Prime Minister Mette Frederiksen and the Minister of Climate, Energy and Utilities, Dan Jørgensen.

The added capacity boosts Denmark’s electricity production from wind by around 12 percent, and covers the annual electricity consumption of approximately 425,000 Danish households. 

“Horns Rev 3 is the largest offshore wind farm in Scandinavia and shows our commitment to Denmark’s ongoing transition to a renewable energy system. The wind farm is a significant contribution to Vattenfall´s production portfolio and takes us one step further in our ambition to enable a fossil-free living within one generation”, says Magnus Hall, CEO of Vattenfall.

The first foundations for the Horns Rev 3 project were put into place in October 2017, followed by the first turbines which began delivering to the power grid on 23 December 2018. During the construction phase, the turbines were shipped from the Port of Esbjerg, but from 2024 they will be serviced from the Port of Hvide Sande, where Vattenfall will establish a new service hub.

“It has taken less than two years from the first foundation was built until the inauguration of Horns Rev 3. An impressive achievement of our employees and partners who now have completed the largest offshore wind farm in Vattenfall’s portfolio. It proves Vattenfall’s position as a leading offshore developer and our commitment to making offshore wind a corner stone in a future fossil-free energy system”, says Gunnar Groebler, Senior Vice President and Head of Business Area Wind in Vattenfall.

In addition to the Horns Rev 3 project, Vattenfall is constructing the offshore wind farms Vesterhav Syd & Nord and Kriegers Flak adding a total of more than 1.4 GW wind energy capacity to the Danish energy system.
