The first of what will eventually become 269 turbines is currently being transported to the area, known as the Pentland Firth, for installation, reports the Guardian. Each turbine is a weighty piece of mechanical engineering, measuring 15 meters tall and weighing 200 metric tons, with eight-meter-long blades. Initially four turbines will be installed at the site, with the rest being added incrementally between now and the early 2020s to create something that will resemble a submerged version of a wind farm.
The site was chosen for the MeyGen tidal stream project because of its particularly strong tides, with currents that can move at up to five meters per second. Those waters will help each turbine produce 1.5 megawatts of power, adding up to a total of 398 megawatts—enough to power 175,000 homes—when the farm is complete.
