Sheringham Shoal Offshore Wind Farm is a Round 2 wind farm in North Sea off the coast of Norfolk. A lease for use of the sea bed was obtained in 2004 by Scira Offshore Energy (later acquired by Statoil and Statkraft), the development gained offshore planning consent in 2008, and was constructed 2009-2011, being officially opened in 2012.
The windfarm has 88 Siemens Wind Power 3.6MW turbines (total power 316.8 MW) spread over a 35 km2 (14 sq mi) area over 17 km (11 mi) from shore.
In 2004 the Crown Estate awarded Econventures (Utrecht, NL) the lease of the Round 2 wind farm site at Sheringham shoal. Econventures together with SLP Energy (Lowestoft, UK) formed a joint venture Scira Offshore Energy to develop a c. 315MW wind farm. Development work for Econventures was to be carried out by Evelop BV, both subsidiaries of Econcern BV. In 2005 Hydro took a 50% stake in Scira, acquiring 25% shareholdings from both SLP Energy and Ecocentures.
In 2006 Scira submitted a planning application to the Department of Trade and Industry for a 108 turbine, 315 MW wind farm.
The planned wind farm was approximately 18 kilometres (11 mi) off the coast of Norfolk at Sheringham, just within the 12 nm UK territorial water boundary, and 5 kilometres (3.1 mi) north of the sand bank known as Sheringham shoal. The wind farm would be located at water depths of 16 to 22 metres (52 to 72 ft) and consist of somewhere between 45 and 108 turbines. Benefits of the site included low shipping and trawling intensities; lack of any dredging, dumping, oil/gas, or MoD practice areas, and of cables or pipelines; as well as low visual impact from the coast, and outside any nature conservation areas. The seabed at the windfarm and offshore cable route consisted of mainly gravely sand, overlying chalk. The electrical power export cable was to be connected to a switching station near Muckleburgh Collection, via landfall near Weybourne Hope. Two routes were considered for the export cable, one avoiding the sand bank atSheringham shoal. The connection to the National Grid was planned to be made at an electrical substation near Salle, Norfolk via a 132kV 21.3 kilometres (13.2 mi) underground cable.
