For the first time, a five-megawatt wind turbine by REpower Systems AG (Prime Standard, WKN 617703) has been set up for the first time on the open sea. The first of a total of two turbines for the "Beatrice" demonstrator wind farm has just been set up on a lattice-like jacket structure, piled to the seabed at a depth of 44 metres in the Scottish North Sea, in the Moray Firth.
Unforeseen problems at the Alpha Ventus wind farm have lukewarm investors reevaluating the billions of euros they have invested in offshore wind energy. Germany's first offshore wind park was dealt a blow with the failure of two turbines due to inferior materials.
E.ON AG and Vattenfall Europe AG are among utilities leading a worldwide push to develop offshore wind power, overcoming a lack of work ships, stormy seas and higher costs to make almost twice the profit they would on land. ...While the benefits of stronger, more frequent breezes offshore are evident to some investors, the risks imply the need for caution, said the EBRD's Zielinski.
"Offshore wind is not for the faint-hearted," he said. "And you need deep pockets."
Offshore wind-energy installations in Northern Europe have lost appeal among financiers because of increased costs and difficulties in building and running equipment miles at sea, a German banker said.
Many lenders have stopped providing credit for installations that are anchored to the ocean floor, said Thiess Harder-Heun, a director at Deutsche Kreditbank AG, which has financed construction of about 700 wind turbines over the past decade.
