Horns Rev 2's location in relation to the wind farms of the German Bight

Horns Rev 2 is an offshore wind farm located on Horns Rev (Horns Reef) in a shallow area in the eastern North Sea, about 30 km (19 mi) off the westernmost point of Denmark, Blåvands Huk. When inaugurated in 2009, Horns Rev 2 was the largest offshore wind farm in the world until Thanet Wind Farm opened on 23 September 2010.[3][4]

History

In May 2008, Dong Energy began construction of the second wind farm in the Horns Rev area, Horns Rev 2. Construction was completed in September 2009[5] and was inaugurated on September 17, 2009 by Prince Frederik on the Poseidon accommodation platform.[3] For the year of 2012, HR2 reached a capacity factor of 52.0%.[2] It receives 51.8 øre/kWh for the first 50,000 hours, paid by electricity consumers.[6] The farm has had some cable outages,[7][8] and blades are being renovated.[9]

Technical description

The Horns Rev 2 consists of 91 Siemens Wind Power SWP 2.3-93 wind turbines with a total generating capacity of 209 MW.[4] The foundations are monopiles like on Horns Rev 1.

Accommodation platform

It has the first offshore wind farm accommodation platform in the world, named Poseidon. It is connected by walkway to the transformator platform,[10] and is 750 square metres (8,100 sq ft) large with 3 decks and weighs 422 tons. On-site accommodation is cheaper and more efficient than transporting service personnel by boat 2 hours from Esbjerg harbour 60 kilometres (37 mi) away. A turbine is visited 10 times a year on average, mostly for routine service, and 1-2 times for fixing faults.[11] Flying people by helicopter to turbines like on Horns Rev 1 is not possible on Horns Rev 2 as the turbines there are not built for it, although the transformator platform has a helipad.[12] Poseidon has 24 rooms of 12 square meters each fitted with TV and internet. There is a gym, kitchen, dining room, laundry room, and a study room. Inspired by Poseidon, a similar platform is being built at the DanTysk wind farm.[13]
