Gwynt y Môr (English: Sea Wind) is a near-completion, 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 1.2 billion Euros were spent on turbines and electrical connections. Construction began in 2012, power production started in September 2013, construction phase ended in November 2014, and final commissioning is expected for 2015.[2]

Design and planning

As with all offshore wind farms in the UK the Crown Estate[3] 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[4] 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.[4][5]

Planning consent for the project was granted on 3 December 2008.[6] The project has a value of 2 billion Euros. 1.2 billion Euros will go to Siemens for turbines and electrical connections.

Two floating experimental LIDAR wind measurement stations have been tested at the site for two years.[7]

Construction

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.[8] Work began on laying undersea cables from the windfarm to the shore in August 2012.[9] In order to feed electricity into the national grid, a substation was built near St Asaph in Denbighshire.[9]

Power production started in September 2013.[10] Final commissioning is expected for 2015.[2]
