The Gwynt y Môr offshore wind power project, located eight miles offshore in Liverpool Bay, will be officially inaugurated by Carwyn Jones, First Minister of Wales. With an installed capacity of 576 MW Gwynt y Môr is the world's 2nd largest offshore wind farm, according to developers.
In total, 160 wind turbines will produce enough power to supply some 400,000 residential households with renewable power per year. The inauguration of the more than $3.18 billion wind farm is an achievement for RWE (60 percent) and its partners in Gwynt y Môr, Stadtwerke München (30 percent) and Siemens (10 percent).
The wind farm extends over an area of some 50 square miles. The 160 Siemens turbines with a capacity of 3.6 MW each and the 160 steel monopole foundations, some weighing up to 771 tons, were installed by means of installation vessels at water depths of up to 92 feet.
Each turbine rises 492 feet above the mean sea level. In addition RWE and its contractors installed two massive offshore substations each weighing 1,433 tons and 83 miles of onshore cable installed.
