London Array - UK

The wind farm site is more than 20 kilometers (12 mi) off the North Foreland on the Kent coast. It is in the area between Long Sand and Kentish Knock, between Margate in Kent and Clacton in Essex.  The site has water depths of no more than 25 m and is mostly away from deep water shipping lanes.  It is north of the shallow cross estuary channel, the Fisherman's Gat and astride of the Foulger's Gat.

The first phase consisted of 175 Siemens Wind Power SWT-3.6 turbines and two offshore substations, giving a wind farm with a peak rated power of 630 MW.  Each turbine and offshore substation is erected on a monopile foundation, and connected together by 210 km (130 mi) of 33 kV array cables. The two offshore substations are connected to an onshore substation at Cleve Hill (near Graveney) on the north Kent coast, by four 150 kV subsea export cables, in total 220 km (140 mi).  It is named after London because the power goes to the London grid.

The smaller Thanet Wind Farm is to the south.

The array is intended to reduce annual CO2 emissions by about 900,000 tons, equal to the emissions of 300,000 passenger cars.
