The Vattenfall roadshow came to town, well the King’s Hall, to tell all-comers about the proposed extra turbines at the Kentish Flats windfarm, 5 miles off the Herne Bay coast.
They lease the seabed from the Crown Estate, and their lease is measured in megawatts (MW) of electricity output. The proposed extension permits 51MW of production. If they install turbines that are the same size as the current ones, they will need 17 new turbines. Their planning application would allow then to install bigger turbines, but there would have to be fewer of them, to stay within the 51MW limit.
The Vattenfall guy I spoke to said that Vattenfall were just keeping their options open as to what kind/size of turbine to install when they start construction – in 2014, according to the plan. I assume their eventual decision will be guided by profit.
