Electricity production by the UK's offshore wind farms hit 7.5TWh in 2012, with 3.4GW installed capacity now operational off the British coast.
Marine landlord the Crown Estate yesterday published its first on the UK offshore wind farms that are operational or nearing construction.
The reveals that there are currently 20 fully operational offshore windfarms with a combined generating capacity of 3.3W. Another 100MW of combined capacity is turning on the 270MW Lincs offshore wind farm, which is under development, and on EDF's 62MW Teesside project.
Last year the industry installed more new offshore wind power capacity than ever before, with over 1.3GW coming fully online in the UK. Completed projects includes SSE Renewables and RWE npower renewables' Greater Gabbard, Dong Energy and SSE's Walney 2 , Vattenfall's Ormonde and Statoil and Statkraft's Sheringham Shoal wind farms.
In total there are four projects, including Teeside and Lincs, currently under construction. Together they represent 1.3GW of installed capacity, the largest of the four projects being RWE's 576MW Gwynt y Môr project off the North Wales coast.
Another two projects — Westermost Rough and Humber Gateway — are contracted and ready to start construction, together totalling 429MW.
Five more schemes, representing another 1.9GW of capacity, have been approved but have yet to reach final investment decisions. They include extensions to Kentish Flats, Greater Gabbard and London Array.
