Several dignitaries, including Carwyn Jones, first minister of Wales, officially dedicated the 576 MW Gwynt y Mor offshore wind farm.
With an installed capacity of 576 MW, the nearly $3.2 billion Gwynt y Mor is the second-largest offshore wind farm and is a partnership comprising RWE, which owns a 60% stake, Stadtwerke Munchen (30%) and Siemens (10%).
The wind farm, located eight miles offshore in Liverpool Bay, is powered by 160 Siemens 3.6 MW wind turbines on steel monopile foundations.
The turbine foundations were installed by installation vessels at water depths of up to 28 meters. Each turbine rises 150 meters above the mean sea level. In addition. RWE and its contractors installed two massive offshore substations, each weighing 1,300 tons and featuring 134 kilometers of onshore cable installed.
