On April 6, the first phase of the world’s largest offshore wind farm, the London Array, became operational. Phase One of the project uses 175 3.6 MW wind turbines manufactured by Siemens and has one onshore substation and two offshore substations. Connected by cables buried in the seabed, the turbines and offshore substations are located in water 25 meters deep off the coasts of Essex and Kent. Phase One has a peak capacity of 630 MW. Total capacity of the project would increase to 870 MW if a second phase is given approval.
