Hywind Scotland, the first floating wind farm in the world, has been officially commissioned to start delivery of electricity to the Scottish grid.
The blades of five huge turbines have begun spinning on the world’s first floating offshore wind farm, located over 15 miles off the coast of Peterhead, Aberdeenshire in Scotland. The turbines stand 253 meters tall, with 78 meters of that beneath the surface, connected to the seabed by chains weighing 1,200 tonnes. This floating wind farm is capable of generating enough energy to power 20,000 homes.
These facilities can only be built in relatively shallow water. Each turbine weighs about 11,500 tonnes, using a large buoy to keep upright. The turbines also make use of new blade technology, which sees the blades twist in order to lessen the impact of wind and currents. They’re all linked together, and the energy they produce is exported to shore through a 30 km cable at a voltage of 33 kV.
