Dong Energy’s 400-MW Anholt offshore wind farm in Danish waters will not transmit electricity to the onshore grid for at least three weeks because of a subsea cable fault that occurred on February 21.
Danish national transmission system operator Energinet.dk said in a statement on Monday that it has located the fault over the weekend, but it is still too early to determine the cause. The fault is affecting the cable near the offshore transformer platform that links the wind turbines and the cable, the firm explained.
Per Hylle, head of the Maintenance Jutland department at Energinet.dk, said that repairing the cable could take more than three weeks because this type of work requires “two periods of reasonably calm weather lasting several days”.
The subsea cable was supplied by NKT Cables.
This is the second time that the wind park has gone offline due to a cable fault. On September 30, 2014, the plant was shut down for seven days after the onshore part of the power cable short-circuited. Because of that, Energinet.dk had to pay DKK 9.2 million (USD 1.4m/EUR 1.2m) in compensation to Dong for the loss of profit during the period.
