Gwynt y Môr (English: Sea Wind) is an under-construction, 576-megawatt (MW) offshore wind farm located off the coast of North Wales. Planning consent for the project was granted on 3 December 2008. The project has a value of 2 billion Euros, of which 1.2B goes to Siemens for turbines and electrical connections. Construction began in 2012, power production started in September 2013, and final commissioning is expected for 2014
Design and planning
As with all offshore wind farms in the UK the Crown Estate owns the seabed at Gwynt y Môr. It has agreed to lease the land to npower renewables. The wind farm will be located close to the existing North Hoyle and Rhyl Flats offshore wind farms. These projects are wholly or partly owned by RWE npower renewables, a subsidiary of German company RWE. In the case of Gwynt y Môr, RWE holds 60%, Stadtwerke München holds 30%, and Siemens holds 10%.
With 160 turbines of 3.6MW Siemens SWT-3.6-107, Gwynt y Môr will be Wales' largest wind farm. The expected output of 1,950 GWh per year is capable of powering around 400,000 homes, or 40% of the homes in Wales. This will prevent the release of about 1.7 million tonnes of carbon dioxide every year.
Construction work began offshore in January 2012 when pieces of rock were laid on softer parts of the seabed to secure the foundations of the turbines. Work began on laying undersea cables from the windfarm to the shore in August 2012. In order to feed electricity into the national grid, a substation was built near St Asaph in Denbighshire.
