Nordex Group has successfully tested a 3MW wind turbine on a 134-metre tubular steel tower at a facility owned by Windtest Grevenbroich for developer GP Joule.

The company had previously installed turbines with hub heights over 120 metres in Europe on hybrid concrete and tubular steel towers.

This was because for high hub heights the diameter of a conventional lower tubular steel segment would be more than 4.30 metres, which would make it impossible to transport them under bridges, Nordex said.

The diameter of the lower segment of the new tower is exactly 4.30 metres, avoiding the transportation issues, it added.

“The results of the latest tests conducted already confirm that the tubular steel tower is perfectly suitable, also given the 20-year service life of the turbine,” Nordex said.

It will make the towers available from the middle of next year for the recently launched N131/3600 and N131/3900 models.

GP Joule founder and chief executive Ove Petersen said: “We are very happy that GP Joule was able to successfully complete the planning and construction of the 3MW turbine on the Grevenbroich wind test field.

“We … will now also take charge of managing operation of the turbine.”
