Vestas Announces New 7 megawatt offshore wind turbine

Vestas Chief Executive Officer Ditlev Engel announced in London their new V164 wind turbine, designed specifically for offshore wind power. Optimized for conditions in the North Sea, Vestas surprised everyone with their announcement of the new seven megawatt turbine, as the announcement was only expected to be of a six megawatt turbine.

This new turbine is designed to rise 443 feet above the waves, with a rotor blades measuring a full 262 feet. This seven megawatt turbine will far surpass the current turbines offshore, with the majority maxing out at around five megawatts. This turbine will also be the first that is 100 percent dedicated to offshore placement.
Vestas plans to have the first prototype built in the fourth quarter of 2012 and full production is set to begin in the first quarter of 2015.
Wind currently accounts for only two percent of global energy, but Vestas is hoping it to provide at least ten percent in 2020. New installations of offshore turbines surged 51 percent in 2010, but Vestas is hoping for a 70 percent surge this year, with the United Kingdom being the biggest provider of wind turbine energy.

This new turbine will be capable of producing enough electricity for 6,500 homes and will make it capable of generating more electricity that any turbine currently out at sea.
Vestas says that building these turbines at sea is understandably difficult, and given that current wind conditions are changing around the world, the construction and operation could become even more difficult. However, they also say that the biggest advantage to these turbines is that there really is no limit on how big they can get. They do believe, however, that this new V164 turbine will work to see them well beyond 2020.

    It would be nice to see a full costing. Price of turbine and maintenance. Cost of overhead power lines to bring electricity ashore and their maintenance. What would be the cost per home, given that there are only 6, 500 of them? In what wind speed ranges is it operational? Does it still shut down if wind speed is too high?

    Here is a fairly thorough fact sheet on the costs of wind power against other fuels.

    and another on efficiencies and loading factors.

    Although these fact sheets are provided by a pro-wind body they appear to be fairly professional.
