Vesterhav Syd and Nord to Raise Efficiency Bar

Vattenfall’s Vesterhav Syd and Vesterhav Nord offshore wind farms in Denmark are expected to have a capacity factor of 52% and increase the country’s electricity generation from wind turbines by 10.7%.

According to the Swedish energy group, the wind conditions at the project location off the west coast of Jutland are excellent and the turbines placed in rows are best suited for the prevailing wind, which in this area is south-westerly to north-westerly.

In addition, Vattenfall said that the Siemens Gamesa SWT-8.0-167 turbine model is optimal for the wind farms and there is no wake effect among the turbines.

“The efficacy of Vesterhav Syd and Nord sets new standards, both in Denmark and internationally. Overall, the North Sea is a fantastic place for energy generation from wind. But the two wind farms are furthermore designed to avoid any wake effect among the turbines. It means that wind will be utilised to the utmost extent and that the farms will make an appreciable contribution to Denmark’s green transition,” said Michael Simmelsgaard, Director of Vattenfall in Denmark.

“If one looks at another Vattenfall offshore wind farm, Horns Rev 3, this is also a very efficient farm but some of the turbines suffer from an internal wake effect. They also encounter wake effects from other farms at Horns Rev. This is not the case at Vesterhav Syd and Nord.”

Vesterhav Syd and Vesterhav Nord will comprise a total of 41 8.4MW turbines, bringing to the overall capacity of the wind farms to around 350MW.

Project construction is scheduled to begin next year, with the full commissioning expected in 2020.


NOTE: The original article has been amended to state that the turbine model to be used on the two wind farms will not be SWT-8.0-154 but  SWT-8.0-167.
