Around 200 wind turbines - to harness the energy in the wind and turn it into green, pollution-free electricity. Each wind turbine will be able to generate a maximum of around 3 to 5 megawatts, and could be up to 165 metres (540 feet) tall at their highest point (to the tip of an upright blade), depending on the exact type of wind turbine installed.
Subsea power cables - to take the electricity from the wind turbines to the electrical substations, and then from the electrical substations to the shore.
2 to 4 electrical substations - to change the voltage of the electricity from the wind turbines into the best voltage for transmission to the shore.
3 to 5 meteorological masts - 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.
1 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.
