Swiss utility company, Elektrizitätswerk der Stadt Zürich (EWZ) and investor Fontavis have together acquired a stake of 24.5% in the 203MW Trianel Borkum II offshore wind project to be located in the German North Sea.
The wind farm, which will be located at least 45km from the shore, will include 32 of Senvion's wind turbines, each with a capacity of 6.15MW. Senvion received the order in last September.
The turbines will each have a rotor diameter of 152m and will be installed on monopile structures. Foundations for the turbines are expected to reach depths between 28m- 33m.
The engineering, procurement and construction (EPC) contract for the monopoles and transition pieces was awarded to Seaway Heavy Lifting in last November.
The offshore wind farm is expected to have a life of about 25 years and it can generate about 800 million kilowatt hours, enough electricity to power more than 140,000 homes annually.
It can also help in avoiding more than 290,000 tonnes of CO2 and 6,700 tonnes of SO2 from entering the atmosphere, had the energy been generated using conventional means.
Trianel management spokesman Sven Becker said: "With the ewz, we have been able to win another large municipal energy provider for the offshore commitment and expand the Stadtwerke family.
"This means that the second phase of the North Sea wind farm will also be realized by municipalities."
