The world’s largest offshore wind developer has warned that low wind speeds are expected to affect its performance this year, highlighting the vulnerability of the renewable power giants to weather conditions.

Orsted expects annual profits to be towards the lower end of its predicted range of 15bn to 16bn kroner (£1.7bn to £1.8bn) due to very low wind speeds in June and July. The period ranked among the worst three quarters in more than 20 years.

Mads Nipper, the Danish company's chief executive, told the Financial Times that wind speeds in the North Sea had been “extraordinarily poor”, adding: “It’s very serious. It is like you’re a farmer and it doesn’t rain.”

Scottish Power and RWE have also suffered from still days in recent months, leading to a 7.7pc fall in half-yearly profits for Scottish Power's renewables business to £304m.

Normally the UK is excellent for wind speeds, as the map below shows:
