World's Biggest Offshore Wind Farm Switched On in Britain  

IEEE SPectrum reports that the long awaited London Array wind farm has commenced operation offshore England - World's Biggest Offshore Wind Farm Switched On in Britain.

Around a year and a half ago, the Walney wind farm in the Irish Sea started spinning and prepared to relish the title of being "biggest in the world." It ended up enjoying that status a bit longer than expected, but the London Array, off the coast of Kent, now leaves Walney and its 367 megawatts in the dust.

Some numbers: 175 turbines. 630 megawatts. Half a million homes. 100 square kilometers. 450 kilometers of offshore cabling.

In other words, it's pretty big. The speed at which these enormous projects are popping around in the waters around the U.K. is impressive, especially considering the ongoing difficulties with getting even a single offshore turbine up and running in the U.S. (Cape Wind might have one by next year! Maybe!) There are now around 20 distinct offshore wind farms around the U.K., generating enough power for 2.3 million homes; when all offshore turbines that are spinning, in construction, or planned are combined, they total 15 gigawatts of capacity—about a quarter of the entire U.S. onshore wind power capabilities.

The London Array, owned by DONG Energy, E.ON, and the U.A.E.'s Masdar, looks to keep it's world's-biggest title for a bit longer than Walney held out, thanks to its already massive size and a phase 2 plan to bring it up to a full gigawatt. And some of the other big projects underway in the region won't be able to compete with that sort of girth: West of Duddon Sands farm will get to 389 MW, for example, while the Gwynt y Mor farm off the coast of Wales will reach 576 MW.

ReNews also has a report on a new 1.2GW wind farm planned for offshore the east coast of England - Hornsea enters the fray.

Smart Wind has submitted its application for the 1.2GW Hornsea phase one wind farm off the east coast of England. ... Hornsea Project One formally consists of the 600MW Njord and the 600MW Heron project. Offshore construction on both projects could start as early as 2016.
