"The strategic focus on maintaining and developing Dong Energy's global leadership position in offshore wind has led to a doubling of earnings form Wind Power in 2013, driven by the completion of the two large wind farms London Array and Anholt" says chief executive Henrik Poulsen.

"A further three wind farms are under construction, two in the UK and one in Germany, and these are expected to be completed in the course of 2014 and 2015."
