Senvion SE, a wholly owned subsidiary of the Suzlon Group, the world’s fifth-largest manufacturer of wind turbines, installed the first offshore wind turbines for Nordsee Ost last week.The RWE offshore wind farm is located approximately 35 kilometres north of the island of Heligoland and is equipped with a total of 48 model 6.2M126 wind turbines.
Each wind turbine has a rate power of 6.15 megawatts, enabling it to supply about 4,000 households with energy. After the planned completion in spring 2015, the Nordsee Ost offshore wind farm will have an installed capacity of approximately 295 MW, enough to supply around 300,000 households with power in a year. Nordsee Ost is thus one of the largest commercial wind power projects off the German coast.
Senvion is supplying all components for the wind turbines and the service platform cranes. At the moment, the hubs, rotor blades, nacelles, towers and other platform components are being pre-assembled as much as possible in the CT1 base harbour in Bremerhaven and loaded onto special ships to be transported to their destination. The installation of the turbines is to be completed this year; commissioning is scheduled from September.
For Nordsee Ost, the turbines are being erected at a water depth of 22 to 25 metres. With the turbines now installed, there are currently 93 Senvion offshore turbines in European waters. Together with the 16 turbines installed on land, Senvion now has experience with multi-megawatt turbines with a total operating life of 350 years – more than any other manufacturer.
Originally, Nordsee Ost was supposed to have been erected between 2011 and 2013; the first turbines were expected to go live in 2012. Due to delays in being connected to the grid, the go-ahead for the installation had to be postponed until now. Andreas Nauen, CEO of Senvion SE, says: “We are delighted that the first turbines for Nordsee Ost are now in the water! A successful energy revolution needs onshore and offshore and wind power in general needs reliable conditions. We consider the acceleration model currently included in Germany’s Renewable Energy Act “EEG 2.0” as reasonable compensation that financing will build on.”
