Gwynt y Môr
offshore wind farm near North Wales
Gwynt y Môr (Welsh for 'sea wind') is a 576-megawatt (MW) offshore wind farm located off the coast of north Wales. At the time of opening in 2015, it was the second largest offshore windfarm in the world. The farm has 160 wind turbines of 150 metres (490 ft) tip height above mean sea level.
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 occurred in June 2015.
In May 2020 plans to add up to 107 new turbines were submitted to Flintshire Council, increasing the windfarm by an extra 41 square miles, with a generating capacity of at least 100 megawatts. This is being developed as Awel y Môr.

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 18, 2026. The linked authority identifier is Q455472. Authority coordinates are 53.450, -3.583. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2015, 2008, 2012 and 2013.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse.
