Project Components

Components of an offshore wind turbine as constructed at North Hoyle Offshore

  • One hundred and sixty, 3.6 MW wind turbines - to harness the energy in the wind and turn it into green, pollution-free electricity.  The turbine tip height will be up to 150 metres above mean sea level.
  • Subsea power cables - to take the electricity from the wind turbines to the electrical substations, and then from the electrical substations to the shore.
  • Two electrical substations - to change the voltage of the electricity from the wind turbines into the best voltage for transmission to the shore.
  • A meteorological mast - to collect wind and weather data, which is needed to design, control and operate the wind farm.

Onshore

  • Underground power cables - to take the electricity from the subsea cables to the onshore electrical substation.
  • An electrical substation - to convert the electricity from Gwynt y Môr into the form required by the national grid.
  • Overhead power cables - a short section of overhead cabling (up to 500 metres) to take the electricity from the substation to the existing national grid overhead lines.
