Siemens will also supply 140 wind turbines for this project, which will be constructed 25km off the coast of Suffolk in the UK. The wind farm will be commissioned in two phases, with the entire construction scheduled to be completed in 2011.

The Greater Gabbard project is owned by Airtricity, the renewables arm of Scottish and Southern Energy. The project was jointly developed by Airtricity and Fluor, which is the balance of plant contractor.

Udo Niehage, CEO of the power transmission division at Siemens Energy, said: As part of the grid connection for the Greater Gabbard offshore wind farm, Siemens is constructing two substation platforms to be positioned at sea in the immediate vicinity of the project. As well as housing the transformers, the substations will also feature high-voltage and medium-voltage switchgear with the necessary protection and control technology.

The two substation platforms concentrate the energy generated by the Greater Gabbard wind farm and boost the voltage from 33kV to 132kV for transmission to shore. The three 132kV high-voltage, three-phase subsea cables will transport the power to the feed-in point, which will be located near Sizewell in Suffolk.
