The 900 tonne RePower 5MW wind turbine, being installed 15 miles off the east coast of Scotland. With an impressive blade diameter of 126m, the blades sweep an area of about 12000 square meters. The turbine operates in wind speeds of 7 to 70mph and is expected to achieve 96% operational level. 38% operational level at full power or about 3300 hours per year. At full capacity it should generate enough electricity to power about 6000 homes. Another five are planned for installation this year.
