The two main European offshore wind farm players – Ørsted and RWE – literally and figuratively felt the lower wind speeds at sea during the first semester of 2021. Ørsted states that wind speeds during the second quarter were among the worst three quarters in more than twenty years. “We are building wind farms with an average lifespan of more than thirty years and have no reason to believe that this will be a structural challenge,” said CEO Mads Nipper. RWE also saw much lower wind volumes in Northern and Central Europe, compared to last year’s very high level. It reported a 22% drop in profits at its offshore unit. The weather isn’t the only challenge for companies in the windmill industry. Previously, some of the world’s largest turbine manufacturers had already referred to the high raw material prices.
