The Scroby Sands Wind Farm is a wind farm located on the Scroby Sands sandbank in the North Sea, 2.5 kilometres (1.6 mi) off the coast of Great Yarmouth in eastern England, United Kingdom. It was commissioned in March 2004 by Powergen Renewables Offshore, a division of E.ON UK. It has a nameplate capacity of 60 megawatts and is able to produce power to supply 41,000 households. Between 2005 and 2010, its capacity factor was between 26 and 32%.[3] Its levelised cost has been estimated at £105/MWh.[4]

The farm consists of 30 wind turbines, located in water from 13 to 20 metres (43 to 66 ft) deep. Each turbine has three 40-metre (130 ft) blades that rotate around a centre-point some 60 metres (200 ft) above the mean sea level. The hollow 4.5-metre (14.8 ft) diameter steel masts that carry the turbines are piled as much as 30 metres (98 ft) into the sea bed, to provide stability on a substrate of shifting sands. These shifting sands have piled up and decreased water depth, blocking access from service vessels. An amphibious vehicle is being built to drive on the sand to gain access to the turbines.[5]

The wind turbines were designed and manufactured by a Danish firm, Vestas. Each turbine has a capacity of 2 megawatts.[6] Turbines were installed by the Danish offshore wind farms services provider A2SEA.[7]


The wind farm has an information centre serving around 35,000 visitors per year, and has become a local attraction.[8][9]
