North Hoyle Offshore Wind Farm is Wales' first offshore wind farm, and the UK's first major offshore renewable power project. Situated in Liverpool Bay, it commenced operation in 2003.
The first of the UK's Round 1 offshore wind farms, North Hoyle covers an area of 10 square kilometres (3.9 sq mi), and is located approximately 7.5 kilometres (4.7 mi) off the coast of North Wales, between the towns of Rhyl and Prestatyn. 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 1,000 MW of green generating capacity for the UK. All of the Round 1 offshore wind farms were limited to a maximum area of 10 square kilometres (3.9 sq mi), and no more than 30 wind turbines.
The wind farm's 30 Vestas V80 Offshore wind turbines are each rated at 2 MW capacity, giving a maximum project output of 60 MW. At the time of installation this was the most powerful wind farm in the UK, producing sufficient electricity annually to power 50,000 homes. Between 2004 and 2010, the capacity factor was between 33 to 36%.
Independent surveys carried out for the operators of North Hoyle have shown that the wind farm is very popular among HolidayMakers and local residents. An opinion poll carried out in 2003, after one year of operation, showed that 73% of people expressed support for the project and only 5% opposed it.
