Swedish energy group Vattenfall and offshore wind turbine manufacturer MHI Vestas joined with the Crown Prince of Denmark and Danish Prime Minister last Thursday to open the country’s largest offshore wind farm, the 407 megawatt Horns Reef 3.

The 407 megawatt (MW) Horns Reef 3 offshore wind farm was officially inaugurated by His Royal Highness Crown Prince Frederik of Denmark along with Danish Prime Minister Mette Frederiksen, and Minister of Climate, Energy, and Utilities, Dan Jørgensen. Vattenfall won the right to construct Horns Reef 3 back in 2015 and the first foundation was laid in October 2017. The first electricity was delivered just over a year later and it is now delivering electricity equivalent to the needs of approximately 425,000 Danish households.

The project’s inauguration was also highlighted by Europe’s wind energy trade body, WindEurope, which declared that the project will boost Danish wind energy production by an impressive 12%.

Built using the world’s currently most powerful wind turbine platform — MHI Vestas’ 8.3 MW V164 model (soon to be succeeded by a number of more powerful turbines) — Horns Reef 3 is delivering electricity at one of the cheapest prices in Europe, at DKK 0.77 per kilowatt-hour (US$0.12/kWh).

“It’s an exceptional privilege to be part of Horns Reef 3 – Denmark’s latest achievement in offshore wind,” said MHI Vestas CEO, Philippe Kavafyan. “The entire offshore wind journey is on full display right here in Denmark, with today’s 8.3 MW machines reliably producing 40 times more wind power than the first pioneering turbines from the early 90s.”

“Denmark is already a leader in wind energy. It gets more of its electricity from wind than any other country in Europe: 41% last year,” added WindEurope CEO Giles Dickson. “This new wind farm will increase Danish wind energy production by 12%. And it’s an important step to Denmark realising its goal of 100% renewable electricity by 2030”.
