The 400-MW Anholt offshore wind farm in Danish waters has restarted feeding electricity to the grid after shutting down a month ago because of a subsea cable fault.
It took over four weeks to repair the cable so that the Dong Energy-owned wind park could be reconnected to the grid, Danish national transmission system operator Energinet.dk said in a statement on Tuesday. The latter is still trying to figure out what caused the fault and expects that the investigation could take several months.
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.
Energinet.dk noted it has not yet determined the size of the compensation Dong should receive following the second fault. It had to pay DKK 9.2 million (USD 1.35m/EUR 1.23m) the previous time.
