Location Map Since September 2012 Greater Gabbard Offshore Wind Farm has been fully operational and exporting renewable energy to the grid. The project is a 50/50 joint venture partnership between Scottish and Southern Energy (SSE) and RWE Innogy. The wind farm, which is located 23 kilometres (~12 miles) off the coast of Suffolk, comprises 140 wind turbines and has an installed capacity of 504 megawatts. The turbines generate around 1,749,000 megawatt hours energy per year, which can provide enough clean electricity to power around 530,000 homes* each year.

The 3.6 megawatt Siemens turbines, are being connected to the grid via an onshore substation at Sizewell in Suffolk. Buried cables (~100 miles in length) connect the turbines to the substation, while three 28 mile long underground cables owned by National Grid Electricity Transmission connect the sub-station to the National Grid. A permanent operations base has been established at the port of Lowestoft.

 

* Based on site specific met mast data indicating a load factor of at least 40%, and based on household consumption of 3,300kWh a year.
