Speaking about the results, Tanti said: ""This has been a difficult year for the wind industry. While market conditions continue to be challenging, we have made encouraging progress. We are working on improving order pipelines the world over.
"To compete in an increasingly dynamic global marketplace we are focusing on developing group synergies with our portfolio of onshore and offshore turbines and market strengths; with our new product additions designed specially for low wind speeds we now have the industry's most comprehensive product portfolio helping us to push into promising new markets while building on our position in key markets like the Americas, Australia, Europe, India, China and other parts of the world."
