The Rhyl Flats project was initially developed by Celtic Offshore Wind Limited (COWL) as part of the UK's Round 1 offshore wind farm programme. COWL received consent for the project in 2002, and in December 2002 the project was purchased by
Npower Renewables (formerly National Wind Power and now a part of
Innogy, a subsidiary of the German firm RWE), who were also developing the neighbouring
North Hoyle and
Gwynt y Môr offshore wind farms. Offshore construction work at Rhyl Flats began in July 2007. Foundation works was completed in August 2008. The completed project was officially opened on 2 December 2009. North Hoyle was completed in 2003, just a few kilometres east of Rhyl Flats. The Round 1 projects were intended to act as testbeds; building the UK's understanding of offshore wind, whilst in total also providing well over 1000 MW of green generating capacity for the UK. All of the Round 1 offshore wind farms were limited to a maximum area of , and no more than 30 wind turbines. The project uses three export cables. ==Output==
