Together with Prysmian, Siemens Energy is to connect a wind farm in the North Sea to the mainland power grid for the transmission system operator Transpower, a subsidiary of the Dutch grid operator TenneT.
The volume of the wind power order for the consortium as a whole amounts to approximately EUR500 million. Siemens will deliver an offshore platform with a converter, two transformers and switchgear technology. Prysmian will provide the cable connection.
"The HelWin1 wind farm project for the turnkey integration of the Nordsee-Ost offshore wind farm into the onshore high voltage transmission grid will benefit from our expertise and many years of experience in this field. At present, we have received orders for connecting offshore wind farms with a rating totaling approximately 4,600 megawatts," says Udo Niehage, CEO of the Power Transmission Division within the Energy Sector at Siemens.
The wind farm is located about 85 kilometers offshore to the north-west of the island of Helgoland. The grid connection will have a transmission capacity of up to 576 megawatts of clean electric power and is scheduled to be in commercial operation by 2013.
