DONG Energy Wind Power

DONG Energy is the market leader within offshore wind energy. Our business unit Wind Power has an extensive track record with more than 20 years of experience within the offshore wind industry. We have achieved a strong market position and developed and constructed the largest portfolio of offshore wind farms in North-Western Europe.


DONG Energy Wind Power has competences across the value chain as we are part of every step of the project - from the early steps of development, during the construction phase, and through to operation and maintenance of the wind farms.

Turning challenges into opportunities

The demand for energy is increasing, and with a growing population globally, it will continue to do so in the years to come. At the same time, there is a rising demand for clean and reliable energy across the globe. This is the dual challenge that we are facing. Wind energy is an example of how DONG Energy operates on the basis of the conviction that we can turn challenges into opportunities which - while they create value for us and our shareholders - also make a positive contribution to the societies of which we are part.

Wind Power is currently bringing row after row of new offshore wind turbines on line. Moreover, we are planning to convert three of our Danish power stations into generating heat and electricity from biomass. We are converting our production, going from conventional power production to renewable energy production with wind power playing a substantial part of our environmentally responsible energy mix. The aim is to deliver reliable and clean energy that meets the requirements of modern society.

Fish enjoy offshore wind farms

Today, reefs are rare in Denmark. Over the years, the number of reefs has decreased, which has had a negative effect on the large variety of flora and fauna that lives on and by the reefs. Consequently, Wind Power has been able to contribute in a positive way to the restoration of nature in the seas in connection with the installation of the Anholt Offshore Wind Farm in 2012-2013.

More than 5,800 large stones with sizes ranging from nearly one metre to four metres in diameter have been relocated to make space for the cables and foundations for the wind farm. The many stones were used for creating 25 new artificial reefs within the wind farm. They promote the biodiversity in the Danish waters surrounding the Kattegat.

The reefs have been constructed in cone-shaped cavitation rock formations which give optimal breeding and habitat conditions for the flora and fauna that live on and by reefs. The cavities in the reefs attract lobsters, crabs and a variety of gadidea. Moreover, various types of seaweed are growing on the reefs. Anholt Offshore Wind Farm verifies that installation of a large offshore wind farm can go hand in hand with restoration of nature. Experiences from marine biological surveys show that the introduction of small, local rock formations acting as scour protection around the turbine foundations have resulted in more animal and plant species appearing.

For instance, a survey conducted by scientists from the National Institute of Aquatic Resources at the Technical University of Denmark shows that the offshore wind farm Horns Rev1 has had no negative effects on the fish life surrounding the farm. The boulder structures also function as artificial reefs.

This provides good breeding conditions with a wide selection of food and shelter from currents, and as such the wind turbines have provided habitats for a range of species.
