The first phase of the London Array offshore wind farm achieved a critical step when it was activated for the first time this October 29, 2011.
Phase one is expected to provide 470,000 homes with 630 megawatts of energy through 175 wind turbines deployed across 90 square kilometers. 15 out of those 175 turbines have been installed since construction began in March 2011.
Phase two will be even bigger than Phase one, with an expected total output of 870MW.
The London Array was originally supposed to have even more wind turbines. However, the project was scaled back due to concerns that the massive wind farm will damage the economically-important red-throated diver population in the Thames Estuary.
The London Array wind turbine farm is a joint venture between DONG Energy, E.On and Masdar. It is located in the Thames Estuary, about 12 miles off of the coasts of Kent and Essex. It is intended to be the the largest offshore wind farm in the world.
