Rhyl Flats is the biggest Welsh power station producing energy from renewable sources. Its 25 wind turbines will power the equivalent of 61,000 households per year and save several tens of thousands of tonnes of carbon emissions.
The offshore construction work at Rhyl Flats began in April 2008. In all, 25 Siemens wind turbines, each with a capacity of 3.6MW, were mounted in an area of nearly four square miles. The foundation piles were sunk at a depth of around 50ft.
RWE Innogy has been running the North Hoyle (60MW) offshore wind farm off the Welsh coast since 2004. Only a few miles further south, the company is planning to build Gwynt y Môr Wind Farm, which will have several hundred megawatts of installed capacity.
In addition, RWE Innogy has a 50 per cent share in the Greater Gabbard Wind Farm located off the Suffolk coast. Following its completion in 2011, this wind farm will have a total capacity of 500MW.
RWE Innogy is also planning to promote the offshore wind business off the continental European coast. In Belgium, the company is involved in building the Thornton Bank Wind Farm, the first 30MW stage of which has already come on stream.
RWE Innogy is also developing two wind farms in the North Sea off the German coast, with 300MW and 950MW of installed capacity.
