Vattenfall has opened Scandinavia’s largest offshore windfarm, Horns Rev 3, in waters off Denmark.

The opening was officiated by the Crown Prince of Denmark accompanied by Danish Prime Minister Mette Frederiksen and the Minister of Climate, Energy and Utilities, Dan Jørgensen.

Horns Rev is 25-40 km off the coast of Denmark and will consist of 49 turbines, providing a capacity of 407 MW. The 8.3 MW MHI Vestas turbines will stand 187 metres high and each weigh close to 1500 tonnes including the foundation. The turbines will increase Danish power production by 12 per cent – enough power the yearly consumption in 425,000 Danish households.

According to Vattenfall chief executive Magnus Hall: “Horns Rev 3 is the largest offshore windfarm in Scandinavia and shows our commitment to Denmark’s ongoing transition to a renewable energy system. The windfarm 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”.

The first foundation for Horns Rev 3 was placed in the seabed in October 2017 and the first turbines began delivering electricity to consumers 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 windfarm 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.

Vattenfall won the right to construct Horns Rev 3 with a historically low bid in 2015 and has since then continued its effort to deliver investments in renewables while maintaining profitability and low cost.

In addition to Horns Rev 3 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.
