Faulty terminal strips in the cables from Horns Rev 2 have shut down the massive wind farm

After just two months of operation technical problems have forced the blades of the world's largest offshore wind farm to stop turning.

But it isn’t Dong Energy’s Horns Rev 2 itself that is the problem. Rather, there are problems with the terminal strip on the 56-kilometer-long power land cable that sends the turbines’ energy on to the grid along the West Coast.

The wind farm has not been producing energy since last weekend and Dong Energy, which owns the wind farm, is losing approximately 1.1 million kroner each day the turbines stand still.

Kim Kongstad, maintenance manager at Energinet.dk, which is responsible for the cable, said the turbines would probably not be back in operation until the end of the month.

'We hope to have all terminal strips repaired by 29 November, after which the cable can be reconnected so the turbines can start turning again and provide power to the grid,’ Kongstad said.Kongstad said that the terminal strips have been a problem since before Horns Rev 2 opened this past summer, where 24 were repaired prior to setting the turbines in operation.

Dong’s information states that the farm’s 91 turbines produce an average of 2.2 million kWh each day – energy sold on to electricity customers both in Denmark and abroad.
