The 400-MW Anholt offshore wind farm is operational again after the replacement of two parts of the subsea cable connecting it to the grid was completed faster than expected.
Danish transmission system operator (TSO) Energinet.dk replaced two pieces of the subsea cable, of about 4.5 km (2.8 miles) in total. The cable commenced operation on Saturday night after 24 days of work.
In early 2015 Dong Energy’s Anholt wind farm was offline for about a month due to a subsea cable fault that occurred on February 21, 2015. This was fixed, but Energinet.dk discovered that two areas of the cable need to be replaced to avoid more errors. Energinet.dk said it is too early to say how much it spent on the replacement.
The wind park located between Djursland and Anholt island comprises 111 turbines of 3.6 MW each, made by German Siemens AG (ETR:SIE).
